Powre Lynz Tools

[mpgmike]

Occasionally I'm asked to either port head with the Powre Lynz or if somebody can purchase the Powre Lynz tools. Since I haven't ported heads for anybody in over a year, the only other option might be to DIY. Previously there was no place to buy the PL tools, but for a limited time only...

I contacted the machinist that made up my Powre Lynz tools to have a new set made. The old ones are starting to show their age with too many cast iron heads under their belts. While on the phone with him I discussed a group buy proposal, and here it is:

I need 5 sets if Powre Lynz tools sold to get the preferred pricing. Normally it would be about $230 per set, but with 5 buyers, they're only $100 for the set of three. General description:

You get 3 tools; a 12 pitch, 16 pitch, and a 20 pitch bit.

The bits are 1/4" shank with 1/2" head. The threaded portion is 1" in length, and the shank is 6" long. The head of the threaded portion is domed for access to recesses and inside curves.

These tools are made of hardened carbide tool steel. There may be a hardened chroming option available, but no promises yet. If available, it would be at extra cost, but would allow the tools to last longer.

I need all monies by August 15. Checks can be made out to Jason Mundorf and mailed to:

Jason Mundorf
13 N. Old Stone House Rd.
Carlisle, PA 17015


Be sure to specify that you want the Powre Lynz tools. Include a shipping address.

I'm sure only those familiar will be purchasing them, but you might want to post a link up to your site Mike or show some pictures so they know what you are talking about.

[mpgmike]

They are the tools that allow the head porter to put screw threads in the intake ports. They allow you to do this:

I don't have pics of my current Powre Lynz tools on this computer, sorry.

sounds like a good deal. hey Mike so you can do basically professional porting of manifolds both aluminum and steel with these

[thefitisgay]

heh problem will be getting 5 people

[turbovanman²]

Have you done any back to back tests, JUST doing the lynz? I am interested.

These Lynz tools are not for the actual porting, they allow the screw thread texture to be added after the port is shaped. They will work on aluminum forever, or do several cast iron heads before dulling. I did a couple of iron heads and that's why I'm getting a new set made up.

As for back-to-back testing, the only test I did was a flow test where a modified intake port was flowed at 10", 28", and 34" of WC pressure. Using conversion tables, numbers acquired at 10" can be converted to 28" numbers (multiply by 1.67) with remarkable accuracy. Either number can be converted to 34" also (multiply 28" by 1.1).

Having the head flowed at 10", the numbers were pretty low. The head was ported, but the numbers were really close to stock when converted to 28". However, when the pumps were turned up to an actual 28" the numbers were pretty stellar. The difference between 28" and 34" weren't very significant.

Essentially this suggested a variable boundary layer. When lift or throttle angle requires little flow, the boundary layer constricts improving velocity. Ast the engine requires more flow, this boundary layer collapses opening up the port to additional flow. My 0.100" lift numbers were always higher than anybody elses.

Other benefits that emissions, plugs, and even burn patterns in the cylinder would strongly suggest is that the Powre Lynz better vaporizes and homogenizes the fuel for more complete and efficient combustion.

Truth be told, my price on the tools is locked in as I do other business with this machine shop. As posted in the listing, this is an opportunity for other people to own these unique tools. I don't touch any of the money, nor am I making anything on the deal. I'm posting this to offer others a chance to get them while I'm having mine made.

ok, i understand now

[mpgmike]

I had response from somebocy in Canada and somebody else in Finland wanting to know of an alternative to sending US funds through the mail. I called Jason and he doesn't have a Paypal account. He doesn't buy or sell online, so he doesn't really need one. He asked me if I could use my Paypal accound to accept funds, then forward them to him, and I agreed.

If you wish to go the Paypal route, the price is $105 to cover the fees.

You must specify you are purchasing the Powre Lynz tools.

You must include a shipping address.

Paypal email is mpgchris [at] yahoo [dot] com

Thanks, Mike

how proven is this??

can the average joe like me port these power lynz in the head?? i have a few castings here id like to do some work too, try things out. and this seems pretty interesting

[mpgmike]

As far as "proven", I will say that there is circumstantial evidence that they dramatically improve low flow velocity (part throttle and low valve lift), fuel vaporization and homogenization, power throughout the entire operating range, fuel economy (by like a large margin), and reduce detonation. Dez put my top end on a 180k 2.5 turbo and made 430 HP at 27# boost. He blew 2 413 trannies before the bottom end finally let loose.

As for skill level, it is much easier than the porting itself. With porting, you really have to be somewhat of an artisan and sculpter. With the Powre Lynz tools, you just need a steady hand. The Powre Lynz tools shouldn't be shaping the port, merely changing the surface texture. If you have a 1/4" chuck die grinder, take your time and you should be stellar.

I did a very similar modification to the head on my Escort after cross pollinating ideas with mike on another site. Despite also doing modifications such as deshrouding and mods intended to increase valve flow 15% and other combustion chamber and port reshaping, which have increased power by at least 20% (Rough figures from timed 0-60mph pulls indicate up to 50%, only started with 88HP :D ) low end torque feels much improved over stock. Now that a strange ignition problem has recently been solved fuel economy is climbing and last tank exceeded the previous stock average.

I guess since I did all mods at the same time, no A-B on that mod alone, all that the persnickety folks will let me get away with saying is "I did it and it didn't screw up my motor." but coming from a scientific background I can say that all the theory behind the mod has a sound basis in fluid dynamics and known properties of IC engine induction systems.

Another place to use these tools would be just to touch around the inside edge of an exhaust port with the large pitch one in the area that will be on the SSR of the flow as it turns into a cast exhaust manifold. This will tend to help the bias flow turning out of the port in the right direction. Shouldn't be needed with headers. So if the manifold goes down and right, just a quarter inch inside the port on the right and bottom sides textured with lynz should be enough. I'd only consider doing the whole exhaust port if you put headers on with primaries smaller than the port opening, or in an all out N/A economy build where recovering exhaust heat into the head can be beneficial (If supported by the rest of the build)

[mpgmike]

So far 3 paid orders have been received. We only need 2 more, and we have 1 week to do it.

id like a set for 100.... anyone else?

[Juggy]

well i will get back to you with my decision b4 the deadline! i too would be one that will be paying with paypal as well. just giving you the heads up in case i do happen to join in on the group buy. will have to try and do some more reasearch. but honestly i dont think there is much to research because you should be able to tell me everything i need to know. all i see is mpgmike everywhere i google the power lynz :p

[thefitisgay]

anyone else bump?

[mpgmike]

Perhaps it would help if I covered the R&D that went into the Powre Lynz tools. Back in about 1998 I purchased a product called the Power Plate. I installed it on my already modified ’70 Duster with the 225 /6. I rebuilt the engine, did some head port work (very conventional), slightly larger cam (252 M Comp Cams), 0.030” bore with otherwise factory style cast pistons, factory exhaust manifold, 2 ¼” exhaust, factory /6 2-bbl carb with factory 2-bbl manifold, OD 4-speed, and electronic ignition. With the addition of a screen under the carb, I took the Duster from a stock 17 mpg to a best of 29.8 mpg. I bought and installed the Power Plate and immediately felt a substantial increase in power and went to a best of 44.7 mpg! (I’m mpgmike, mileage is important to me.)

The Power Plate was a 1” aluminum spacer that went between the carb and intake. It had a coolant jacket with a coolant inlet and outlet. They were “T”d into the heater core hoses. There were tapered cones under the throttle plates. The cones were 8 degrees with a 20 pitch thread turned into them. The cones extended about ¾” under the throttle plate gasket.

As good as it worked, I realized that most of the vehicles on the road were PFI, and the Power Plate principle would somehow have to be placed between the fuel source (fuel injector) and the combustion chamber. It took me about 2 years to come up with the Powre Lynz concept. I had LL Brown (the company making the current batch of Powre Lynz tools) make me up a single tool that had the 20 pitch thread, with a ¼” shank that I could mount in my die grinder, and a 3/8” X 1” head with a domed head. I did several sets of heads with just the 20 pitch with very encouraging results:

Dez: ’89 LeBaron, 2.5 turbo, 180k miles. Ported head, ported factory exhaust manifold, ported 2-piece intake (said porting done by me). Dez added larger turbo, injectors, FMIC, custom cal, water/meth injection, and a few other minor mods. He went from factory 156 HP, 23 mpg city, 27 mpg hwy to 430 HP @ 27# boost, 35 city, and 43 hwy. He destroyed 2 413 ATs before wiping the 180+k bottom end.

Fltcoils: older gentleman, so no power numbers, ’88 Sundance 2.2 TBI. Stock 25 mpg city and 29 mpg hwy. Modified got 35 mpg city and 42 mph hyw.

Diamondlarry: (2 heads) ’96 Saturn SOHC 1.9 L, 38 mph hwy stock, 65 mpg hwy modified. Noticeable increase in power. Done with only the 20 pitch Lynz.

Diamondlarry: ’99 Saturn DOHC 1.9 L, 34 hyw stock, 57 mpg modified. Registered 130 HP stock (accelerometer) and 165 HP modified.

These are the only numbers I received, but I had anctedotal reports of really incredible results from well over a dozen other individuals (without documentable numbers).

I did get results when I was only using the 20 pitch thread Lynz tools that under certain operating conditions, power and mileage improvements were considerable, but under heavier loads, the results seemed to go away. That got me thinking about the thread pitches and what could be done. I had LL Brown make me up a set of Powre Lynz tools that included a new 20 pitch, but also 16 and 12 pitch threads. Now I could tailor the pitch to the velocity zones in the ports. Results got much better. Higher velocity zones, such as short-side radius’ were treated with a coarser pitch, while slow velocity zones were given the finer pitch Lynz.

Benefits seemed to improve across a much wider operating range. I was definitely on to something. I’ve worked on Toyota VVT-I, Mopar 2.4 head/2.2 block hybrid, Saturn DOHC, Viper V-10, 8-valve 2.2/2.5, SB Chevy, 3.5L V-6 Chrysler, and probably others (I’m going from memory here, so bear with me). Based on feedback, I formulated what pitch was appropriate for what range of velocity zone. Some of the heads were performance oriented, and others were strictly fuel economy oriented. The more feedback I received, the more I knew I was onto something big.

I ported a 2.2 8-valve head and added the Powre Lynz and sent it up to my machine shop to be flowed. I requested them to flow it at 10” water column pressure, then at 28” and finally at 40”. Their 3-pump flow bench was unable to get results at 40” and maxed out at 34”. To convert 10” to the industry standard 28”, take the 10” numbers and multiply by 1.67 and you will get numbers very close to what you’d actually get flowing the same port at 28”. When they flowed this head at 10”, the 28” equivalent were about 138 cfm. This is barely comparable to a stock head (about 142 cfm). The one I sent them was ported. HHHhhmmmmm!!! When they flowed the head at 28”, the numbers came in at 182 cfm. This is comparable to many porter’s best work (excepting Steve Menegon, of course). The difference between 28” and 34” was insignificant (28” numbers X 1.1 = 34” numbers). Maybe it just wasn’t that much of a jump like 10” to 28”.

What this suggested to me was a variable boundary layer. Fact: My ported heads always flowed better at 0.100” than everybody elses (including Menegon’s). This was with the Powre Lynz, as I was using conventional 3 angle intake seats and 5 angle exhaust seats with mild back-cuts on the valves. It appeared that at low flow conditions; low valve lift or low throttle body opening; the boundary layer constricted causing high velocity (a good thing), regardless of the size of the actual port. As the engine demands increased, the boundary layer collapsed allowing additional flow.

About 2 years ago I had my new (to me then) 3-piece Powre Lynz tools made up. I offered a group buy, but without even 1 taker. Since then, I quit porting heads for the general public. I received way too many requests for head porting that utilized the renouned Powre Lynz. I repeatedly turned the work down, as my day job doesn’t afford me the time to spend on such things anymore. I recently ported my IROC R/T head and realized that my PL tools were getting pretty dull. I contacted LL Brown about having a new set made up, and thought of the several people that requested either the tools or the porting work. I decided to offer a group buy. I have my price on my Powre Lynz tools and that doesn’t change. The group buy offers the PL tools to any takers at a reasonable price (individual prices comes in at $230 per set from LL Brown). All money goes to Jason at LL Brown. I don’t receive any profits from this group buy, it’s just a favor to LL Brown and the community in return for the favors shown me over the years.

I hope this helps.

i was gunna put a screen under the carb in my truck but i forgot which angle you told me

[mpgmike]

Hold the screen straight upright, then spray Brakleen across the screen. Slowly angle the screen away from the can (top away, bottom stationary. When the spray disappears, that's the angle you want.

Mike

[mpgmike]

We now have 5 confirmed orders. The rest is icing on the cake.

[moparloper]

I am very interested now that I've finally seen some reported MPG improvements. Can I assume from the ALLPAR article that the roof gets the 20, the sides get the 16 and the SSR gets the 12. The pictures only show so much, will you be willing to supply more info on exactly where to apply the grooves? Or do they extend all the way from manifold face to the seat?

[thefitisgay]

Thaks.

There will be an instruction sheet included with pictures to help you make the most of your Powre Lynz tools. I have to spend some time at the bench with grinder in hand. I will be making up the instructions with my old tools, so some of the pics may not represent the tools you will be receiving.

[thefitisgay]

thats just what i was hoping for sweet

[moparloper]

Payment has been sent through PayPal. I want to be sure that recipient for the payment was "newlifeforu", is this correct? From this point what do you think the ETA will be?
Also thank you for all your work in this area and for sharing that info!

[mpgmike]

NewLifeForU is correct. My wife picked that one. Jason will commence manufacturing early next week. It takes about a week to finish. The baking process alone takes 2 days. Delivery should be in about 2 weeks from Monday, give or take a little.

BTW, we now have 8 paid orders from my end (Paypal). I don't know how many checks Jason has received. I tried calling him this morning, but got his answering service. I think a new movement is about to begin!

Mike

[mpgmike]

As of 8 PM EST, Saturday, August 15, 2009, we have closed the Powre Lynz Group Buy. We have 9 paid orders received via Paypal or cash, and so far none received by check/mail. Thanks to all that looked with interest, and especial thanks to those that participated in this program. I assure you that there will be much hoopla on the net about Powre Lynz as these 9 people experiment and report their results.

Just wanted to give everyone an update on expected ship date. I didn't realize the time fame would be so long, but here is the quote I received today:

"...I'm ordering material today. It's probably going to be a couple of weeks until I get it fit in.

Thanks for the update, :thumb:

[moparloper]

Any word on when these might ship?

[mpgmike]

I've been told the Powre Lynz tools will be shipped next week (week of 10/19).

Mike

[mpgmike]

Official word is that the Powre Lynz tools were shipped today, 10/23.

Mike

[Reaper1]

Nice to hear from you Mike! I hope you're doing OK...last I heard you were fighting a pretty crappy battle.

[thefitisgay]

got mine today

[Jack's Dodge]

I cannot believe I missed this!

Anyone interested in reselling? PLEASE?!

Any possibility of another group buy?

[mpgmike]

Jason decided to give enough time for the folks that have already received their tools to use them and get the head(s) on the road. Once positive feedback starts coming in and new interest is generated, he plans to do another run. Have no idea of time frame, though.

Mike

[Jack's Dodge]

From a financial perspective, Jason's position is understandable. Why he did not return any of my phone calls 5 months ago about having this made are still a mystery. Lost his number when allpar.com reformatted the site. Mike, I spent plenty of evening listening to your ideas, methods, and the visit to your old place are all the proof I need. If additional funds cannot sweeten the deal, could someone post pics of the tool so I can have them made? This have some projects to complete before I can get back to my own.


Oh, will to trade some of these items for said tools:
