Boost Issues

Alright, I found the stupid thing. Funnily enough, it was starring me in the face the whole time. There is only one hose that connects to the throttle body (before the butterfly) and its right there.
The f#*ked thing about this hose is that it goes into one of the metal lines that accompany the fuel rail (you know, on of the two that go under the throttle and over to the other side of the engine) and then simply stops, like nothing connected to it. I pulled the hose of the throttle body and blew in it (minds out of the gutter gentlemen!) and fresh air came out on the other side, I couldn't believe it. I grabbed a hose and connected it stright to the top of the charcoal canister, took it for a drive and its much better, less popping and farting. I'm wondering if this could have been making the engine run lean this whole time. If the engine gets more air than what is read by the afm (i.e. under vacuum), would this not make it run lean? Under boost I don't think it would have been a problem as boost would have come pissing out that little hose. Anyway, still no boost in first gear so I'm starting to think Evan might have been right and the turbine side of the turbo may be rooted. I'll have to wait and see. Anyone here ever use a 200sx (s14) stock intercooler before? Its 300x240 (overall) and 180x220 (core size). Will she handle 14 - 15psi? Some pics of it.
Cheer's for the help fellas.

bah that'll do 12psi easy. It'd just get heat soaked quicker thats all.

Heat soak is when the intercooler has reached (or exceeded) it maximum efficiency and juat isn't doing any good anymore.
To stop heat ingress into the intercooler pipes in the engine bay:
get some fibreglass wrap, like you see on performance exhausts in the engine bay.

Re: fibreglass wrap
yeah, it works. I've seen it on an exhaust and you can touch it after it's been running hard for a while.exanator wrote:does that fibreglass wrap really work???

The principal idea is that it's a really really good thermal insulator. And if it can keep all that exhaust heat inside the exhaust, then I'm pretty sure it'll keep engine bay heat out of your cooler piping.

Re: fibreglass wrap
understood NOW WHY DO THEY WRAP INTERCOOLER PIPING WITH IT IF ITS MADE FOR KEEPING HEAT IN??? DOES IT ALSO KEEP HEAT OUT AND IS IT PROVEN??? this stuffs pretty expensive so jst wanna do some home work b4 i invest!!!The Renegade wrote:yeah, it works.
