i purchesed the ebay turbo back....i like it its nice and all.....i dotn knwo if its normal.....i installed it.....not even the check engien light went on....everythign was fine....than the light went on as expected....but thats not the problem


problem

when i drive and gun it.....goes faster.....but on diffrent gears on diffrent rpms like 3rd and 5000k....i hear a pop....stops speedign up and just pops once.....limiting the acceleration....,..something is deffintly wrong and its not normal......sounds like a back fire idk.....just i dont want that......cant race with that...


kinda like....a rev limiter sound....stops at some high rpm and pops!!!


anyone any feedback.....


thank you very much

 

knock maybe? i dont know any of this stuff but ive heard thats what knock sounds like. a turboback exhaust will lean out your engine and even though most evos run rich from the factory, some dont and it could be that you are running too lean and getting detonation. i dont know though im not an expert

 

what is the cel? and did u connect the o2 sensor back in the mix?

 

what is ebay turboback i think is the real question here . is it a reputable company at all? maybe its just a peice of garbage ? who knows

 

maybe i run lean...recommend a tune?



cel...i dont know lol..yes....the sensor is connected back in the pipe...


any suggestions what else could that be......running lean makes sense...it does sound like a detonation.....

 

there was a reveiw....xs power...or osemtihng...its that exhasut.....its good.....its not the exhasusts....fault i bet.....idk....i get that POP!!! on some rpm and thats the problem ,....screws everytihng up....cant accelrate properly like that....this has to be fixed asap....i know its not good

 

It's piping, you know like every other exhaust out there including the expensive one you bought. Geezzz

 

Do you have a MBC? Installing a TBE sometimes give you higher boost, sounds like you may be hitting a boost cut. Try lowering your boost, or better yet get it tuned.

 

I agree with Dan. I bet you're hitting boost cut. ^^^^

 

Could it be a loud DING instead of a POP? a ding could be your exhaust hitting the subframe/steering rack.

 

Boost cut is my guess as well

 

I dont think u have to install a mbc for a tbe. Is the clearance of the TBE right?, i mean it's not touching the acd and stuff. If its a pop, maybe the TBE is hittin something. Check to see if everythin is installed right and looks smooth.

The ebay tbe i heard someone had it in the forums and with that he rans low 12's with the supporting mods of mbc, flash, and etc. So its not some crappy product- hoopefully :/

The o2 sensor is that in? Cause thats the reason for the CEL usually.

 

It sounds like boost or fuel cut; you just need a tune.

 

If it was just hitting something why would there be a sudden stop in accelerator as he clearly stated in his first post, its boost cut. An MBC should be installed to adjust the boost accordingly.

 

Holy spelling checker Batman!!! (just had to get that out of the way).
Now does the exhaust you bought have a cat or HFC?
I would assume not. The "pop" you are hearing is most likely backfire from unburnt fuel racing out of your exhaust if you don't have a cat. You are most likely shooting out fireballs out your exhaust.

Do you have a boost gauge?
You need to check your boost to make sure you are not experiencing boost creep. That is when your boost steadily rises with your RPMs instead of going up then down. Then you would most likely be experiencing boost/fuel cut, which would account for the sudden loss in acceleration.
