With a recent speeding ticket and a few car repais, my budget went low for the month and so I can't go get dyno'd. That being the case, I was hoping that some of you, more experienced and knowledgable users might be able to give me a decent ballpark of what to expect.

My 2005, Base model Z was dyno'd before any mods at 235 whp.

Since then, I've addedthese aftermarket parts:

custom xpipe with magnaflow exhausts.
DC headers.
High Flow Cats.
Kinetix intake plenum (the big shiny one)
a plenum spacer
K&N CAI

i haven't yet had it tuned since adding these but i'd like to. in any case, i guesstimated that maybe i'll see gains of around 35 whp. Is that too much, too little, about right?

i'm at that point now where i have to decide if i wanna start modding for N/A ir F/I, but i haven't yet decided. That's a different thread topic altogether, though. Here, I'd like to get input on what kind of gains I should expect to see (realistically) once i can afford to dyno again. Thanks!

 

250 whp is my guess but who knows depends on dyno and other variables.

 

Do you mean after tune? Cause with all that on there you BADLY need to get it tuned... that said, with the Osiris tune you should end up around `~260WHP.

 

Sounds like a pipedream, would love to see pics of the plenum combined with the spacer.

 

id say 260+/- is a solid guess. the de doesnt respond very well to bolt on's, but your onto a good start if you plan on doing any future mods. if your serious about n/a horsepower check out sgmotorsports and talk to sasha. theyre closing in on 380+rwhp n/a

 

Its a troll dude. Or just a bench racing build that he has a hard on for.
