I have a question about the hahn stage 2 turbo...my buddy got his car dynoed at 193 hp at 10.6 psi intercooled on his eclipse rs....he has the front mount and everything with an exhaust...does this seem about right...also what is the max horsepower on the 420A stock?????

thats a gain of about 76whp. not bad.

but doesn't that seem a little low for 10psi, i know the 16g is smaller then the turbo that comes with the star kit, but wouldn't you expect breaking the 200 mark with 10psi?

i honestly know nothing about hp gains from turbos depending on size and psi though so idk, is it tuned well?

auto or manual tranny?
IMO you should be a little over 200hp with the manual tranny.

what kind of dyno? mustang,dynojet,etc..??

mught just be poor tuning or no tuning of the fuel.

youre just about on the money to be honest.

it is a automatic tranny and it was dynoed on dynojet...also what is the maximum wheel horsepower on the 420A???? thanks guys

do you mean on the stock motor? Probably around 230whp depending on how good the motor is, and thats probably pushin it.

thanks buddy helped me out alot...:)

I get 202whp off 7psi with a star kit, I wouldnt expect the smaller turbo to be than much lower.

now those are the numbers i like to see, now when i get a set of 330's and a way of keeping the boost from going past 7psi after 5k rpms i can get mine tuned and dyno'd..........to bad that's about forever away

I remember somebody posting 200WHP on the hahn kit only boosting 5psi. Search around its here somewhere and his car was stock with exhaust etc.

i hit 222whp and 219 ft/lb of torque at 7 psi
about a year ago now
it would have been more but i was running way to rich
