well i finally got my evo back with my new superleggaras and i am happy with the look. well anyway i was cruisin' around and ran in to my buddy with an sti and he told me he just got a dowpipe, he had a cat back to begin with so now hes got pretty much a turboback right? anyways he says it a lot faster and now he can take me bla bla bla. i dont care to race him since ive beat him before dp and im still stock but i guess my question to you guys is without any tuning what so ever wouldnt that cause him to lose power? ive done a lot of research on the matter but i just cant figure how changing the A/F and also losing psi on an already low boosting car can do well? just curious and would like some thoughts on it.

 

no, you won't lose power. and you beat him stock?

 

yeah i beat him and he had cat-back. and yes i was stock a have an 04' RS and i ran a 13.3, 13.4, and a 13.5 nothing else. he ran a 13.4, 13.6, and 13.7 at sacramento raceway. hes a damn good driver and had the car longer. i came from an 95 integra gsr so i didnt know shiat about launching awd.

 

yes.

Not necessarily, although i am not familiar with the 2.5L Subaru motor & setup, but generally turboback systems give power without a tune. When I installed my buschur I noticed a quicker spool time and more top end power, and I haven't had a tune yet.

 

Does this surprise you? Last time I checked EVOs and STis dynoed very similiar and have been running similiar times since both cars arrived in the USA. Honestly I don't even think it's much of an argument when it comes to the 05 EVOs, they are faster and quicker.

 

I agree, good post.

 

so, off topic im getting turboback but i dont know whats the best setup. i live about 25min. from vishnu here but i dont have time to tune. i guess i need advice on a good turboback setup, either peiced from diff. vendors, or just all one brand hit me up. thanx
