420a 20g turbo dyno chart

[Rage-Tek420a]

I have a 95 eclipse 420a with a Hahn Racecraft turbo kit. With a 20g anyone know how much power these things can hold?

I have made so far 395 HP. With built bottom end, 22 intake and 24 exhaust cams, Megasquirt, 750cc injectors, 3inch Exhaust, Pump gas.

Dyno sheet comming soon !

theres no exact or even real ball park number for turbos, it all depends on your tune, engine efficiency and supporting mods, really you wont know numbers until you dyno and tune the car

The boost spiked to 22lbs and fell right away to 15 then krept back to 22... We have not had the chance to finish the boost control settings.... It was late =)~ simple fix but went home.

Do you have a dyno chart so I can compare.

500 hp is the upper limits of the 20g

Not bad at all. Did you log the run with MS by any chance. It would be nice to view that also.
