Last nite i was with some ppl and one of them had a Evo 9.... His Mods are... ( Full 4 Inch Ams TBE... MBC 19Psi.. Front Mount... And K&n Filter... Then he kind of Drove it hard... Then at the Gas Station He would Turn On then Die Out... Any Ideas Whats Wrong with it??

 

he has a 4 inch exhaust with a k&n filter running at 19 psi? is he tuned? is he nuts?

i woulnt think that oversized exhaust would cause it to stall. 4 inch???

it might be his unnecessary aftermarket fmic.

 

No his not Tuned.... His waiting for His Gt35R.... And it stalled on 2nd Gear on Him. His been haveing that Tbe for sometime now and he didnt have any problems with them.

 

well for one thing a 4" exhaust is huge for only having an air filter. Second of all the turbo on the IX is supposed to be putting out like 22psi (correct me if im wrong) so if you are putting out a lower boost and have a huge exhaust i could imagine that the car would act weird especially if it hasnt been tuned.

 

20.16 psi boost @ 3500 rpm (WOT)

 

Does he have a K&N drop in or the cone one?

 

i feel sad for some peoples Evos...

 

Lol i was thinking the same thing. 4 inch exhaust? FMIC before cams? 19 psi? No tune???????

 

What a erratic pattern of mods: 4"TB,FMIC,cone, no tunning.. no wonder why the car wouldn't start. Neither the FMIC nor the 4"TB is neccesary at those entry levels. I want to bet a 2.5" or 3" exhaust and a stock intercooler would have produce better results.

Also, I just surfed the AMS website and they don't have any 4" exhaust listed. I start to smell something here.... You guys know what I mean?

Also what is the point of a MBC if you are only running 19psi?

They do custom make them so its not impossible for him to have one, however i was thinking the same thing. Its probably the 3" ams tbe with the 4" tip

 

Yeah but I highly doubt a prestigious shop like AMS would even dare to build a 4"tb for such aplication. I doubt they would built a 4"TB for that customer with such mods. Everyone here knows that a 4" TB would hurt you more than help you on this particular case

Nope, despite what the factory says, it is 22 psi. Verified by 2 different gauges in my MR last night, when I thought the autometer was screwed up. This was a 2nd gear pull and it held it without tapering till about 4000 rpm. No mods other than an open airbox/K&N drop in. New exhaust didnt get here on time so nothing else got added.

Gauges used- Autometer Ultra lite carbon 30/30 and an Isspro 0-35

 

i thought i read somewhere on here there is no such thing as having too big of an exhaust for a turbo car. correct me if im wrong..

 

sounds like he poppped an IC hose or pebkac.

 

I concur wholeheartedly. And those diagnosing the problem as being a large exhaust on a turbo car....here's your sign.
