Fbo 1le 530/495
Been doing alot of testing with my '17 1le with the hi ram. Added a ati ud pulley and speed density tune from Dave Krysienski @ EFX tuning and some minor modifications on the hi ram since last i was on the dyno. Unfortunately i didnt get a baseline when my car was stock on this dyno. Final numbers are 530/495. Now to get to the track...timeslip coming soon!
Mod list - My ported holley hi ram/95mm tb E85 Speed engineering 1 7/8ths headers Speed density tune by Dave Krysienski Velocity stack on hi ram Ati ud pulley https://youtu.be/qLL20wdFVXE |

That’s bad ass.
Have you seen how much power drops with heat soak with the aluminum manifold ? I’m guessing this pull was not heat soaked |

Stout numbers sir, looking forward to seeing them timeslips.
Their is still quite a bit of pump and injector window left at that power level.

NA can go a long way on the stock fuel system being the fueling demands are much less then FI.

So uh, are these numbers really high or am I missing the mods that are adding almost 130whp over stock?
I ask because I think I need all these things. |

The limiting factor for power range on these engines is not the valvetrain, it's the shitty stock intake manifold. Thanks to the C7 the 6th gen had to suffer as well. With VVT, we can still make good use of the added rpm the high ram adds.

With no baseline you can't even really say anything about the numbers either way, it could be a super happy dyno and started at 430 rwhp. Trap speeds will tell the tale.

Dynojet sae corrected is usually pretty accurate at most places. But I guess you never know
I’ve seen other hi ram bolt on cars over 500 too. One of PRAY’s cars did 505 with an a8 still in 5th gear. |
