    Magnets are your friend for getting intake mani washers when they might have fallen into odd places. Thats a bummer on the radiator though. What kind of warranty did/does it have?

    Probably only 1 year. It doesn't seem to be leaking actual coolant...Just bubbles of air when its completely empty and under ~10psi of air with soapy water sprayed. I WAS happy with the radiator when I put it in but this makes me feel irked. Actually bought a new radiator instead of the millionth used one like the Duster.

I messed with the EARL's 90 fitting and I think the O ring type washer has failed. At first it seemed loose but tightening it did not help. I can't really add a second O ring in there but I have heard of people making giant copper crush washers..however that works.

    Re: The Holset he341 3.0L

    Because my lower radiator hose is leaking badly, just bought from Rockauto:

    BECK/ARNLEY 0394003 (039-4003) Water Pump O-Ring $ 1.08 10 $ 10.80
    DORMAN 626303 (626-303) Heater Hose Assembly $ 20.79 1 $ 20.79
    DORMAN 626302 (626-302) Heater Hose Assembly $ 16.02 3 $ 48.06
    FEL-PRO 35336 Thermostat / Housing / Water Outlet Seal $ 0.71 3 $ 2.13
    GATES 28411 Heater Hose $ 0.69 6 $ 4.14
    GOODYEAR 61469 Radiator Lower Hose $ 6.40 2 $ 12.80
    GOODYEAR 3029 (3029:P) Bypass Hose $ 1.94 2 $ 3.88
    MOTORAD 7240192 (7240-192) Thermostat $ 6.02 2 $ 12.04
    MOTORAD 7240160 (7240-160) Thermostat $ 6.79 1 $ 6.7


    The 20 dollar heater hose assembly is the transmission side water pipe. its not exactly the correct one for our cars so I just bought one. I think its one of the minivan styles. I can always cut off the extra piping if I ever use it.

    I also bought a bunch of B-Quiet sound damper product (lighter then dynamat xtreme) for the Duster and I will probably sparingly put some in the Spirit eventually.

    Re: The Holset he341 3.0L

    Mention that Rock Auto sent out those 2 lower radiator hoses and one of them is oddball and missing a bend (not made in the same factory) and after my wife bugged me I called and they are sending me another one and letting me keep the oddball hose :P Yay.

    Messed around with my Holset oil inlet fitting some more. Had purchased copper crush washers, used one, and still had a leak. I don't know if the crush washer was leaking but I still had a leak and when looking more closely I saw that the AN fitting was not tight enough to seal on the hose end. This is the connection that I normally take apart when disassembling things. Tightened that and used copper RTV on the copper crush washer and let it sit for a day. Didn't check it yet but still commuting.

    I have been thinking a bit about how my modified throttle cable cam messes with the drivability of the car. The rpms are very easy to control but it makes the car feel sluggish since 1/4 pedal barely cracks open the throttle. Its hard to get over this. I feel this less with the same modification done to a larger 65mm tb vs the ported 58 on the Spirit.

    In the future you will ask your phone how to get a better throttle cam and it will automatically translate and outsource your request to a cheap foreign solidworks designer who will email the design back to you so you can print it out in your 3d printer.

    Re: The Holset he341 3.0L

    I was going to take the Spirit to the track and make a few slicked passes on it during the NW Honda Meet BUT as it was being loaded onto the dolly the intercooler was just low enough to catch and get the bottom protection plate torn back on one side. Breaking that weld also exposed a nice hole in the end tank. Boo. Going to see if my coworker can fix it.

    I was really hoping to see if the clutch would give out as it has been giving some bad signs. That will have to be addressed.

    That's exactly how i ran a 15.2 with my 14 second 3.0 Dynasty. And a 15.8 with my 14 second turbo van although i wasnt actually DDing that one. Why not?

    Brent should tell me where the cheapest unsprung 3puck disc is sold so i can buy one for the aries and hand-down the 4 puck to my caravan and go race it again.

    Dont push the red button.You hear me?

    Re: The Holset he341 3.0L

    I would think Clutchnet has the cheapest, but I ordered a unspring 6-puck and received a sprung 6-puck... So you may or may not get a unsprung...

    Re: The Holset he341 3.0L

    The thing i dont understand is i remember seeing those discs for like $70 there in the past and now they are $159. I can buy a dual diaphragm pressure plate and run a stock disc for about the same money. A $70 disc is a no brainer but at almost $200 i have to actually think about it.

    Re: The Holset he341 3.0L

    Right now they are 10% off and the price includes shipping (so $143, shipped). Strangely, the 4 and 6 puck clutches are cheaper...

    Re: The Holset he341 3.0L

    Hey, I really like the 6 puck and my experience with Bansheenut's 6 puck was that they alternate rivet directions and that (or some other factor) actually caused a difference in wear. 3 pucks on each side were tearing up the most on a slipped clutch (weak plate that when replaced with a better one made the clutch hold high rpm VHT soaked 24.5x8 MT slick launches).

    I posted picks of this someplace but I am actually thinking about a 6 puck if I can get somebody to rebuild the old +40% real TIII plate that I have in storage which has a few thousand miles but bent straps from a misshift. Bansheenut seemed to like the engagement of his 6 puck a lot and I figure a +40% TIII should hold a LOT more on a 6 puck then a 4 puck combined with a billion mile OEM equipment T1/3.0 plate.

    The 3 puck is bad to the bone but Kyle (Billet PT6262 powered 3.0 Acclaim) says his engages fairly roughly. Mine works great. Can't explain the difference. Stock material flywheels are definitely better.


    BTW this intercooler never had any provisions for bolting to any structures. I might be changing that since the damage in the middle of the tank and fins on the backside is from wear/vibration against the chassis.

    Man, it's a shame you never have gotten to drive my Daytona with the TU Purple Plate and 6-puck disc. I think you would like it.

    Looking at the intercooler, I guess it might have been a small blessing in disguise that it got damaged. The damage caused by the vibration was going to cause some issues eventually, too.

    Yes. The damage in the middle would have been nearly unrepairable if it went through.

    Re: The Holset he341 3.0L

    Funny thing, I guess my coworker did a leak check and actually welded 3 of the tubes AND the location in the center that was damaged. Then found a lot more small leaks. I don't think he had fun because he said he sold his high frequency box years ago and that lets him do nice pretty welds whereas he was just "scratching" this one. He wants me to buy a new one next time I wreck this...or build something so he has an excuse to buy another high frequency box.

    I reoriented the intercooler higher ~2" and added some zip ties to both lift and pull the intercooler forwards. Also added rubber to some locations where it will or can hit steel. The Evo endtanks are a real pain. Had to remove more material from my driver's headlight frame and I shimmed both headlights outward slightly. Passenger headlight already had direct contact between the bulb housing and IC piping (already cut out all the headlight frame in that spot).

    Re: The Holset he341 3.0L

    Had to replace the fusible link that powers the OEM ASD (auto shutdown relay) and ecu and coil and fuel pump relay and alternator field. Not sure why Dodge wanted to have so many things powered by one fusible link or why they have to splice it at so many different locations. I had the first 30 amp fuse blow out right away when I turned the key "on" (didn't even know it was the correct fuse) so I went through all the systems, disconnecting them all and looking for a short to ground. Only ground was where the various power wires hooked up to the ecu (not sure why that is). Anyways I finally got the guts to put it all back together system by system and the fuse didn't blow.

    Then for fun,

    I tried an audio recording of knock on my wife's a670 Spirit and in the cold weather it made noise but I couldn't say it was knock compared to recordings I took last summer (I might have taken the timing back from 15 degrees to 12 base timing). Those also had an audible knock but on the program Spectrogram version 5.0.6 does not show the same loud knocking sound or any sound at 6200hz. I had turned the recording volume down a little so I don't know if that made a difference. The audio recording sounds clean compared to what I actually heard in the earbuds "live"

    Then tried a recording of the He341 Spirit and it did not make the audible knocking sound during light load driving. I couldn't make a 3rd or 4th gear pull because its damp and the tires just spun. I was going up a giant hill to help add load and try to make it knock. Spectrogram did not show any knock. That makes me feel a LITTLE better but I need to get a recording with traction and full boost. It doesn't knock during spoolup before it spins so I feel good there. I think the stock timing map is actually very good for a moderate to large turbo because timing is pulled after 2400 rpms which is when the turbo spools. Timing doesn't come back to what it was at 2400 until over 4500 rpms.

    Re: The Holset he341 3.0L

    Glad you got it fixed. I was actually going to suggest that you start taking away circuits until things quite blowing. You got there before me!

    Also good news about the knock recordings (well the good things that came out of it anyway). We could always hook your car to my truck and then let you car try to pull my truck up that hill! Then, if it brakes we already have a towstrap and a tow vehicle!! :deal:
