Those are pretty impressive numbers for a GTX3076. Which turbine housing were you using? Did you have to increase base fuel pressure so you didn't run out of injector to hit those numbers?

The first graph is the wrong one. That's the same one you posted in the 6266 thread.

Was that 485whp on straight pump gas?
What RPM do you get full boost at? I've been wondering about upgrading from my GT3076 to GTX3076 so I'm really curious about where the powerband starts with these turbos. |

Op have you had a chance to take the car down the 1/4 mile? Curious about trap speeds seeing on mine was hitting those mid 90's idc's at the 500whp mark (stock base pressure) on a relatively similar set-up. |

Its exactly the same, my friend just upgraded only the turbo and tuned today, spool is basically identical on his setup.

3076 gen 2
That graph only shows the e85 pull but boost is coming in around 3800-4000rpm Base pressure is set at 50psi or 50 at FP differential, I don’t currently recall pressures under load. Have not had a chance to play with the car sadly, to busy on customer cars. The 485 pull was on 93, the 607 was on E60 as we did not drain the tank after the 93 runs. |

Looks good!
The gen 2 30r really throws down compared to the old 30r. |

That is a boatload of power. What boost and/or timing are you running on E85?

That's some power from a 3076 and 1300cc injectors! Would be a weapon to drive with that fat torque curve! How much boost to make the 600?

Very nice, even on 93. I have the G2 3576r with S2 cams and 2kcc injectors, and am hoping for similar numbers. Hopefully my spool isn't much later without avcs.

Full boost at 4k would be fine, that's what I get now. Part of me thinks that I should go smaller though, like a 3071, and try to get slightly better spool and slightly more power. I'm actually pretty content with the power I have now, and like you said the gtX3076gen2 is a pretty big jump. |

I was asking the OP about the drag strip seeing we have a very similar set-up but I have a gen 1 @26psi and that is a gen 2 pushing 29-30psi. Dyno's are great but if you can get trap #s it seems to be a more helpful reference point. Imo |
