intake mods

[shadow88]

This has been my winter project. I figured bigger's better, so .......enjoy! I goofed it up a bit, so start at the bottom. ok? cool.

Looks good, Wonder how it will perform? are you only changing the manifold or a bunch of stuff?

[shadow88]

I plan to use a tbi style exhaust, 255 fuel pump, afpr, new clutch, and upgraded turbo. The intake has a few small leaks that have to be patched first. Then I'll add to vacuum ports.

After that I have to guess the power output at 19-22 psi to properly choose a turbo and clutch to match. any guesses?

It has a 58mm tb and that really is the smallest part of the intake track.
This morning I was testing cold start injectors to add the additional fuel.

On the upside, this cost countless hours and about $210. And It MUST be an improvement over the stock intake. (as seen in the 3rd pic from the bottom).

I really would like some inputs on the estimated power #'s

Before the manifold swaps it had around 230ishhp and around 280ish torque at the flywheel.

Any guesses would be nice to hear.

[shadow88]

Damn, again, start from the bottom. I spaced out and forgot to bring a torque wrench, so it should run monday evening (for my neighbours) it only has about 2 1/2 feet of exhaut tubing on it. Next up is longer pipes for the turbo/intercooler, because it's set back a little more. enjoy!

For that type of setup, I see no reason not to go with a hybrid turbo, and a 4 puck ceramic clutch. Call chris at TU, and he will be able to point you in the right direction. That thing should scoot. Although I would try to do some thing other than an extra inj. set up, as the rest of the parts are pretty nice. Why go with some thing that is less than ideal when putting that much time and energy into a project?

i think its pretty sweet and good to see new ideas popping up!

on another note to go with that shiney intake...

POLISH UP THAT VALVE COVER!!! haha good luck!

[t3rse]

i thought about doing the exact same thing. ever think about using velocity stacks? looks good, now i will have to get mine going, feel left out now!

[Dave]

That looks great! I'd like to see some flow bench comparisons actually.

About how long did that take you?

[shadow88]

on tuesday night, it ran for the first time in months The fumes from the exhaust are too much to allow me to stay in the garage to bleed the cooling system. It seems the 10 degrees or so the oil return tube is on is sufficient, no smoke.

crodes, when it's running well, it'll go to a dyno and THEN the proper turbo will be purchased. As for the 5th and possibly 6th injector set-up....I have a 3 bar controller from Dean Stillie and although it's great at the strip, it's kind of on or off for normal driving. This IS my daily driver.

lynx853, polish? you don't know me very well, I work on something for function over form, when it works right i stop. But I do have a SHELBY valve cover to go back on.

t3rse, pm me with any queston you may have about making your own. By veloticty stacks do you mean just longer runners? never seen velocity stacks on a boosted car.

Dave, I do not have access to a flow bench so, sorry, no numbers, but I'd venture a guess it's capable of flowing more air than either 1 or 2 piece manifold. It took 4 months of late nights at work after work. Sorry to sound like a jerk but i made it to flow on a car, not a bench.

Thanks for the inputs and keep 'em coming!

3/4 down the page or a better picture of a different intake...

quote from above page: "Velocity stacks to go on the end of the runners were shown to improve airflow by 19% on the flow bench over straight tubes"

Nice work!

How are you going to do your velocity stacks? Stephane posted this link in another thread: http://www.rossmachineracing.com/uni_intakeparts.html

edit: I can't get the link to load now, but I remember it being awesome.

[LynX853]

The S is silent... that link dosnt work... just lettin ya know

It looks like they changed the name of it...or I just suck at posting. Either way...here's the real one.

[LynX853]

that site is AMAZING! thanks!

[shelbyplaya]

hows the car drive with the new intake? and up-dates?

WOW, I could easily drop a few grand there,

[shadow88]

Yeah, actually, I do have some updates.

This thing's a beast. Turbo lag has seemed to increase about 150 rpm. I suppose that's due to less port veloticty. But when she comes alive this car gives a new definition of TORQUE STEER!!

I have the exhaust completed in 2 1/2" pipes with a cut-out that's capped right now. Still no leaks and it's briefly been above 25 psi.

It seems to produce just as much power at 16 psi than it used to at 21 psi. I'm waiting until the weekend to plumb in the cold starts and reposition the fuel lines (very close to the swing vavle).

I'm sorry to say- work keeps me busy enough to not have enough time for my shadow. But soon enough, it'll be ready for a trip to the dyno and eventually to the track. - sorry Ontario guys who may be reading this- it's just not ready for this saturday at st. thomas.

Thanks for showing intrest in my frankencar.

What did you use to weld the flange onto the TBI mani? How long have you been running it, and have you had any cracking problems? I like the intake, I want to build one and yours has made me think outside the box!
