Did you get any check engine lights after these mods?

 

I can't speak proper english, so i can't answer your question J/K

i will dyno tune it next weekend, maybe i can prove myself wrong about the spool up rpm. i will bring back the dyno chat next weekend. Stay tuned

 

no check engine light.

here is my current mods

apexi intake
JIC exhaust manifold
Helix o2 housing
turboXS downpipe
utlimate racing highflow cat
Megan racing 3" catback exhaust
vishnu xede with FP ( next weekend )

 

I thought a stock EVO got to full boost by 3,500 RPM's

 

Noticed the exhaust manifold is thermal wrapped. How important is that? I'm installing a borla manifold which is ceramic coated and it looks sweet. I had planned on wrapping it before I got it, but now that I have seen it I don't want to wrap it. Can you only wrap one tube? Like for cylinder 4, so that you keep the radiator hose cooler?
Thanks for the pics.

 

my car start pulling from 2.5k rpm. Full boost is around 3.5k rpm

 

I like the idea of wrapping the header but whoever did yours didn't do very well at all. I also don't think that ceramic coating AND wrapping the same part is a good idea. Do one or the other. Did you put the O2 sensor into the new housing before you installed it to make sure the threads were good?

 

i did the wrapping myself, i know i did a poor job on it. my mechanic put the o2 sensor into the housing before he installed it.

rpm-evo:
The reason for the wrapping is to lower the engine bay temp.

 

Oh, sorry Dave, I didn't mean to offend!

 

The wrap will also decrease time to full boost...

 

Boost is not the only way to make more power on the topend. Boost with less restriction means the turbo does not have to work as hard to make the same boost and thus has lower compressor discharge temps, forcing higher density air into the engine and making more power.

Who cares about his spelling!

 

why would ceramic coating AND wrapping the same part not a good idea? Thanx

 

HAHAHA.

You go correcting people and look at what you wrote. forgot or you meant forget, people are a trip in this place, always downtalking someones grammar.

Who care's if he mistyped, he got his message across and that's all that matters.

 

don't worry about it... even my mechanic said i did a Sh*tty work of the wrapping. Long as it works, that's fine for me.

 

well i used to use this header also and i noticed it pulled beter to redline also, i dunno about how much it helped get spool faster but it was definatly noticable that it was spoolin alil quicker! btw i got a used thermal coated JIC header if anyone is interested = / in perferct condition!
