how much power can i achieve with my stock evo 8 turbocharger? anyone know any true numbers? not just guesses.

 

All you are going to get is guess work with your question. Why?

Because, is your Turbo a 03-04 9.8 hot side, or an 05 10.5 hot side? That would make a difference.

Also, you don't list any mods, . How can anyone tell you what power you are going to make without this information, never mind true numbers.

Certain parts make more power than others. An Exhaust System with a Cat will make less power than one with a TP.

Too many factors, Boost?, Fuel?, Cams?, brand of Parts?, Etc. All will change the outcome of the final numbers.

Not a good question with the information given.
True numbers can only be get by taking the car to a Dyno. Even then, people still argue about them.

And you don't want any body to guess?

 

well i should of mentioned that my car is basically stock besides a kn filter and a invidia catback that i will be installing in a few days. also how can i tell what type of turbocharger i have?

 

oh wait nvm ive got an 03 so im assuming the 9.8?

 

Please don't ask such vague, newbie questions. Be specific and ONLY make a thread AFTER you've searched the topic. This topic has been discussed countless times. Also, there is a newbie forum for newbie questions...

 

You can make a lot of power on the OEM turbo. Your best bang for your buck will be to get a 10.5 hotside, port it out really nice, get a SS o2 housing, and then a ported exhaust manifold. There's lots of other things that can be done before upgrading the turbo, port the intake manifold and TB, alky injection w/ more boost, etc etc.

I'm at the point where I am at the limit of my OEM turbo, but I'm just goign to upgrade to a stock IX turbo, probably my last chance for true cheap bang/buck whp gains.

Real numbers: on E85, I have a friend with an IX putting down 350whp on dyno dynamics (400+ on dynojet).

My car puts down ~335whp with ported exhaust stuff, doing ported IM&TB + IX turbo to shoot for ~375whp on dyno dynamics.

 

Also, as warr says, search search search on this topic. There's lots of little power gains to be had on the oem turbo setup.

 

+1!!!!!!!!!!!!

Also, it depends on the dyno you use.
Look in my sig. at my power with an viii turbo/10.5 hotside
280cams/alky/tb exhaust/BR race fmic w/ pipes/etc.

I don't think you could pull much more power to the wheels without changing the turbo.

 

Max power will all the boltons and a right combination of parts and meth or race gas you can see 400-420whp. It won't last for long though, the hp that is.

 

Alky/meth Ftw!!!!!!!!!!
