Strong numbers. Look forward to seeing your graph.

He made 200rwhp/345rwtq at 3k. The engine peaked at 436@6400 rpm. Torque curve is very flat. If he didn't have those heavy 315s and about 150lbs in his trunk it would have definitely hit 440+rwtq but we weren't going for that inflated dyno number. This was in 95* heat as well even though it shouldn't make any difference in SAE numbers.
#6
Baseline was about 365rwhp/345rwtq. Not sure how much that intake is holding him back but I know it was pretty heat soaked. If he had a fast 92 on there it would definitely hit 450+rwhp.

Another Typhoon 85mm intake car making low #'s sorry i hate that heavy heat soaking intake. looks good but that about it. I bet you would be about the same with a ls6 intake and 40lbs lighter

I dont think it dyno'ed low at all. I think 436rwhp is respectable, I could see if I had a set of AFR's or TFS heads, then that would be a low dyno # but this was a budget minded build. I got typhoon intake from a friend for a cheap price, cheaper than a used LS6 intake. The heat soak didnt seem to effect the dyno numbers seeing how all the pulls were very close to eachother.

Those same heads i have put in a few cars with cams smaller then yours the T2 cam and one auto car did 444whp/398trq on a mustang dyno and the m6 cars did anywhere from 450-460whp. Waiting on 2 other cars with same setup but with MS3 cam to dyno do i can get results on those 2 cars. Maybe it was the heat? How hot was it when you dynoed it? and who tuned it?

It was 94 degrees but as said above, that shouldn't have much bearing on the SAE hp correction. I'm sure on a nice cool day in the Fall, it would put down 445-450 uncorrected.

those are killer numbers, whatever the intake is!
Some plp are having hard time reaching over 440rwhp even with the FAST...just dyno numbers after all. I killed some 500hp+ cars with my crappy 387rwhp
Your mph tells you have a very fast car.
