Well my modified (jbweld) starion intercooler i bought from 93lsivic finally broke today. My question is, can i take the intercooler off and drive to a shop to get it welded? Would this cause any problems leaving a gap in the piping?

 

not a good idea, leaving the piping off will let the turbo over rev which is no bueno, you can however get a length of pipe and run no I/C to the shop just dont go crazy boostin n ****.

 

what broke and where?

 

I'm thinking his jb-welded intercooelr outlet broke/melted off...

 

umm if he took the intercooler off....he would see no boost...just keep the throttle low?

 

throttle wouldnt matter, its still producing exhaust gases which will (over) spin the turbo from what i have heard. best idea is to put a length of piping in there.

you will have NO problems what so ever driving with the intercooler off. You can rev it as much as you want. The turbo will create no boost because it will go into the atmosphere and all the engine will get is natural air as if it were stock. A turbo cant over rev regard less cause its always regulated by the wastegate which is on the exhaust...not the intake.

 

Wrong, the wastegate is activated by pressure, not flow. Unless your turbo is large enuf to pressurize the entire atmosphere, it will overspin and the wastegate wont even crack open.

 

*uNF*

 

if there is no pressure in the intake there will be no pressure in the exhaust. exhaust pressure is what moves the turbine.

 

There will be pressure in the exhaust, just not as much. And pressurizing air causes restriction on the compressor, which causes restriction on the turbine, which causes backpressure. Without the laod from the compressor, the tips of the ehxuast wheel will roughly come close to the velocity of the exhaust gas. I guess someone with alot of time could roughlycalcuaate all of that out with ehxuast speed and the diam of the turbine wheel. I do udnerstand what you are trying to say tho. Your theory is probably 100% correct with larger turbos, but you can overspin a small turbo doing that.

 

thanks for trying to be smart, but no.

 

if there was so much back pressure like your saying there is...to over rev the turbo...since your saying its pressurized, then the wastegate would work...like you just say it wouldnt.

Wastegate is activated by INTAKE manifold (or turbo outlet or wherever u get the vac from) pressure. I'm talking about backpressure in the EXHAUST manifold, turbos create more backpressure And while backpressure DOES help spool, I never said the backpressure overrev's the turbo... what will overrev the turbo is all of the exhaust energy going thru it w/out the wastegate opening.

 

ah what to do what to do? The pipe broke off
