11% correction factor is pretty far out there. lol. STD and smoothing factor of 2 don't help the cause either. That would equate to 470 uncorrected.

If the correction factor is accurate, you should be trapping 133+ mph in the 1/4 mile.

Either way.... power drops kinda fast on the top end for a ported MSD. 13.1 AFR is fairly lean for E85..... it's not on the verge of blowing up, but I would definitely keep an eye on that.

Take it to keystone and see what it traps.... if it's below 133 mph, then that dyno might be a little generous.

I wouldn't expect a legit 520whp car to trap 133 full weight unless it's at Cecil county in November....and even that is a stretch. GPI's Heads SS4 cam full weight car trapped 127 on 20's and it was cold out.

Dyno is a tool for tuning. Track ets and mph are the true test of how much hp it makes. Don't get to wrapped up in that but it looks good on the dyno sheet. Have fun with it and enjoy the new found power you spent your money on. Congrats.

Meh... I trapped 127 mph at OPs track with 460 rwhp SAE (470 STD) at full weight. That's with a converter, which soaks up about 2 mph/20 rwhp.

525 rwhp - 490 rwhp = 35 rwhp. Would an additional 35 rwhp and it being an a10 over an a8 pick up 4 mph? I'd think so

Humidity is 78% in Miami...right now, according to my weather app

Actually the real numbers in SAE are 502/489.
