I'm thinking about maxing my current gtx3076. Maybe in June 2019 at 27-30psi.. waiting till June next year because by then I'll have a new demo every month from work when I hit diamond club level. Currently I'm on stock block .1600ccs. any guesses on the power level? I'm sticking to gtx3076 because it spools quick. I'm sticking with act hd pp that I have installed.

What fuel pump? Would single fbm340 work with 2200 CC's and, stock fuel line?

​​​​​​Only upgrade I would like to consider is around headstuds. And springs and reraibers. Andy recommends supertech...

I've seen some other guy on other forums run the gtx3076 up to 34+ psi and they're getting gobbs of torque past 29psi...

 

on the stock compression/stock block you will max that turbo out way before 30psi. I maxed out my gen 1 gtx3076r on the stock block at 588whp at 21psi on e85.

 

Hot side AR and manifold will also be a very big contributing factor.

450 pump will make 5-550 on corn with 1600s.

 

I got cha. On stock compression 11:1 .What if I run a headgasket down to 8:1 and run 2200 injectors? I've seen lots of subie guys push over 30psi on gtx3076 but I think their compression ratio is 8:1.

Would it even be worth it to run more boost at lower compression or just keep 19psi at 530whp
