How much wheel HP does our Street Hellcat make on our Dyno?

[ostmike]

How much power do you think our street Hellcat makes? This is the "before" hit for our header test.
Important info:
Car has gone 9.3 at 147 with this pulley combo on the tired stock shortblock.
We switched to a 426, 11.5:1 compression, and Thitek Bear heads. Everything else is exactly the same. Spinning to 6700.
Video with the answer and header results coming out soon. Let's see how close you can get.

Every dyno different so hard to say. Fairly close to my car- best is 9.12@149 with a whipple at 22 psi on e85 at a weight of 4685 so will be cool to see

It makes way more power than my car. Now do I win the prize for guessing correctly?

I made 905 stock everything except e85 and a 5” pulley (the biggest one) on a “safe” flex tune (4.5 whip). I’d expect this car already make more than that running 9.3
