Yeah just an experiment. I know most haven't tried it but the damn turbo and crossover bake the **** out of the upper intake piping. So I know header wrap is designed to keep heat in but thought I would try it. I wrapped the piping in regular header wrap and then in 2000 deg reflective insulating wrap. Hoping to reflect alot of the heat off the pipe and then cold air (especially under meth) should keep the air inside the pipe nice and cool. Might not be able to see in the pics but the meth jets are just before the reflective wrap where the pipe comes up from the intercooler. Will see more when she is under boost how well it works. I can say that the carb intake heat soaks quickly but also cools off just as quick soon as you open the throttle.

THanks to all for the compliments...

Running a spec 4 from last year. See how long it holds. The 6spd is alot of fun on the interstate but an auto would sure be nice at the track. Would have to go 4L80E though...couldnt deal with 3 gears LOL!!!

It looks nice. How large of a DP do you have? What's the rest of the exhaust setup? How high do you plan on revving it? I'm just asking because I feel you might run into some back pressure issues.

Well, it doesn't take a brain surgeon to say it's ridiculous to wrap up anything that is trying to dissapate heat. There is no way that wraping up the cold pipes can help. Let them breath as much possible.

Dp is 3.5". It is going straight into a 3.5" dynomax bullet just after the trans on pass side and then a turn down well before the axle. Back pressure with the huge exhaust housing and abbreviated exhaust shouldnt and has never been an issue. Especially since it never goes over 65-6800. Usually shift well before 6500.

I don't think "needadvice" understands that the wrap is highly REFLECTIVE. And that especially when under boost and meth (when it counts) the cold air coming from the intercooler and jets is QUICKLY cooling the inside of the piping. I can tell you after tuning today that the wrapped piping certainly doesn't seem to be hurting anything. Temps are high at closed throttle but with the IAT mounted in the back of the elbow they are going to be no matter what. Crack the throttle and they plummet rapidly. We were starting the runs at 100-105 IATs and ending at 95-99. 15.5 psi with meth. Not too bad if you ask me. Especially on an 80+ degree day. Much better then the IATs from last year that would end at 120-130. And that was with the IAT mounted right after the meth jets!

But then a meth nozzle elbow started leaking very badly so we had to call it a day. Do some more tuning maybe weds after I get some new meth fittings.

Prob dyno late this week.

That front shot of your car is pure sex, OMG

The opposite will happen. He's losing power by wrapaing the cold piped, period.

Yes off course you know all just like in every other thread you ever post in. I'm seeing the IATs and am convinced for now they are as good or better then with the hot turbo baking the unwrapped piping. The only way I would lose power is if the IATs were higher then they could be. Not the case so far. Period.

Thanks. I will post some more pics of the exterior when I get a chance.

I've been trying to hold my tongue on this issue for a while now, but I'm glad someone finally said it.

LOL yeah luckily ive seen enough of his dumbass flaming remarks in other threads to just ignore anything he says.

Once we get the meth fixed and the tune finished I will try to get some video up

Setup looks good. I'd highly suggest going bigger on the DP though, maybe run a Y and a second 3.5" pipe. You may not have backpressure issues yet but I would bet a wooden nickel you're giving up a good amount of power.

What are you baseing your information on?

Mr.MartyStone

iTrader: (12)

You have a 427" motor with an 85mm turbo, it's a no brainer. You're leaving power on the table with a single 3.5" even on a N/A build. There are a lot of results of guys picking up power everywhere when going bigger on the exhaust.

I would agree that bigger is usually better as far as turbo exhaust systems are concerned. Joel offers a 4" dp also. But it is so tight where my 3.5" dp is under the drivers header that it would be tough fitting without hitting anything. Had to modify the 3.5" some to keep it off the steering shaft.
Supposedly the 4" fits somehow but I'm not ready to try it yet. If I don't make the power I want or should I will def consider it. Its almost an open dp setup now as it is. No catback at all.

I'm sure its choking it off a bit but think its still good for close to 1k rwhp. Power and boost arent dropping off at all by 6500 rpms. 15-16psi run so far. The higher the boost and rpms desired the more chance of backpressure being an issue. This is really 90% street car so doubt will be running much over that boost wise.

How is plug access. I want a kit like this for next year. Looks great!

If you're not seeing an issue I wouldn't be worried about it, just putting an idea in your noggin. I dig the dp though, minimal is my middle name
