Well just wondering, I can use this as a reference the next time I get on the dyno, but whats the norm for IATs on the dyno with about 11-13PSI of boost doing a flat-out 4th gear pull, taking into consideration that a 4th gear pull on a Z06 would go up to 165mph.

Mention the ambient temps as well, boost level and type of FI.

Thanks.

Last trip to the dyno ambient temp was 86*, procharger, 11#'s. Highest IAT's I had was 118* this was through the twin 4.5 coolers from procharger.

i'd like to know as well , as i think i'm outgrowing my intercooler outside temp was 70 and iat were around 220f @ 20 psi !

When I did mine at 13psi the outside temp was low 80's and the IAT's usually got up to 111 - 117 depending on the pull. This was with a Procharger D1SC through my horizontal FMIC.

i run carbs, but inlet temps should be same deal, above the carb
with temps in the 80's, my last dyno test (LS engine)was a little over 105 after the 3 core sheetmetal i/c, around 12 lbs boost, large fan blowing on it
a while back, i had a gen 1 engine i did some testing on, around high 80's, at the track, with 18 lbs boost, i had a reading of 330 degs out of the supercharger, 189 after the i/c, going into the top of the carb
i never took a reading under the carb, surley would have been cooler
where are you guys taking the readings on FI cars? before/after the throttle body? prob would be the same, since the air wouldnt hit the fuel untill right at the cyl head
i never had an engine related problem with the gen 1 engine at the high temps, prob some advantage with the hot air/fuel mixture right at the carb
the i/c on the gen 1 setup was underneath the car, not the best setup
on the LS engine now in my chevelle, its right in front, prob much better airflow, so reduced temps
