20g turbo questions...

[dominick1985]

I just purchased a 20g turbo external wastegated. my question is what kind of rpm should i expect spool up?...i have 680cc injectors and a afc2.Whats a good psi on pump? I ran 18 pn my 14b with jus a rewired fuelpump and it loved it.

it really depends, on a few factors, you can have different spool up times, depending on the wheel stage of the turbo and the housing of it, the 20g comes in 2 different versions basically, the TD05H and the TD06H, you should expect spool up from 3000 to 3500. regarding the injectors, you won´t be able to tune them with an safc they are pretty big, the max to tune an safc are 650CC injectors, and people have a pretty hard time tuning them, you can expect very erratic timing curves, etc. i would go with http://www.dsmchips.com, and buy an eprom ecu if you don´t have one already, or just save for dsmlink. with proper tuning you can go 20-22 psi daily. good luck.

Depends on your fuel pump get a 255 if you don't have one and get a fpr before turning it up to 22 psi.

If its a tdo6 I would say full spool between 3200-400rpm depending on your set up. 20-22 psi on pump I would guess with a good tune. SAFC can tune 680's pretty good but a chip would help. 20g's are great pump turbos you should beable to get 350-400whp on pump

i'm in the middle of getting a eprom and a stage 3 chip from dsmchips.com u say 350-400whp i am a pretty good driver what kind of 1/4 mile times can 350-400 push out?
