Default Dynoed the T76.

Finally got the car dynoed with the 76.
This is @ 12psi on the same tune the 60-1 was running, except I adjusted the fuel to get the A/F close, Which actually turned out very close.
Maxed out the maf at about 5000rpm so that's why it gets leaner up top. I'm gonna adjust the tune a bit throw a LS6 intake on along with a walbro fuel pump. Then i'll bump the boost to 15psi and see what she lays down.

Not bad though I gain 110rwhp and about 70rwtq just from the turbo swap.

I'm hoping after the LS6 and a cam swap I'll put down 650-675rwhp @ 15psi. Do you guys think this is possible?

Also I'm gonna replace my stock intank pump this weekend. Can I leave my stock pump in there and run it like a twin setup with the walbro? I want to be safe but i think twin walbros would be overkill.
Thanks

There is no reason why you shouldn't be able to get to 650rwhp. I am running a similar setup only on a Z06 (single turbo T76 GTS). At 14psi, I am at 650rwhp on pump gas and pretty conservative timing.

Spark advance is 16* @ TQ peak ramping up to 20*@ HP peak. IAT averaged 100*F base 139*F at the end of a pull. Kinda high but it works for now.

Nice power numbers. 110rwhp was well worth the swap.

Thanks.
Yea, It's the street kit.

I was running 12psi on the 60-1 when I made the 425rwhp 500rwtq.
Here's the 12psi 60-1 graph.
