I am currently running a single (not stacked) twin turbo headgasket. What is the maximum amount of boost I could run safely? Thanks.

tell it starts to detonate. ;)

what injectors do you have, what turbo, what fuel system, what ignition

its about 9:1 compression. with a good tune 20 or so psi on race is very possible. mabye 25, with a really good tune

16-18 might be possible on pump with a very good tune. otherwise i wouldnt do more then 14 on pump, cource im running 14 on pump with 10:1 compression

Thanks! I just wanted to make sure I could run my 1 bar spring with no issues. I am running the following

60-1 Turbo
Walbro fuel pump
Single tt hg
Stock injectors
VPC
Emanage
I will be installing my 550 cc injectors once i get everything else worked out.


Would I be safe at 1 bar on stock injectors for now? Obviously I will tune it/dyno it first but I want to be sure I even have a chance. Thanks for the help.

From what I've been reading and the na-t persons I've been talking to, 1 bar of boost on stock injectors and stock fuel pump is NOT a good idea :sadwavey: .
