what's your guesstimate? First turbo build about to hit the dyno for tuning. What's are yalls expert opinions on what my combo will make at say 20#. It's an 02 lm7 with callies rods, weisco pistons, ljms stage 2 cam, stock heads with tooley springs and trunion upgrade, all arp hardwear, proflo intake and tb, 160# injectors on e85 with dominator fuel pump, eboost 2 boost controller, tial wastegate, big red bov, build 4l80e with freakshow turbo convertor, with a single pte gt4276 with 1.28ar. What kind of numbers can I expect on 20# |

What kind of numbers can I expect on 20# You never mentioned whether the converter is locked or unlocked. That will make a huge difference in dyno numbers. I'm going to say somewhere around 780 HP with the converter locked and a very conservative tune. |
Sorry it's a lock up 3600 billet converter |

What injectors?? 780whp |
Cool. I was shooting for 800. Sounds like I might be achievable |
860! ;) |
4l80 might soak up a little power I'd guess 740-750 |

Sweet. I might just push it till I run out of turbo. Hopefully it will impress me. I have alway been a na guy with alcohol injection. |

Screw it. I was gonna post the first start up video but can't figure it out |
get it on youtube |
Just going by similar setups I've seen Through a 60 mine made 730 at just a little less boost We have fairly similar setups engine wise, I'm using two cheap turbos, he's using one nice one. Figured his would dyno a little higher with 2 more psi, but would lose just a bit more drivetrain wise. Post up a graph when you have it done, don't see that many people use those turbos, be nice to see how it compares to something similar in size |
