Drove it home. Didn't get on it because didn't have vacuum line on the big because of relocating it. Didn't have issues before or after. Iats on way to friends were 5 over ambient and same on way home. Haven't done wot pulls. Was 120f before end of half mile so have to wait and see.
Yes z06 and zr1 frame bumper support etc are all aluminum and easy to weld too.

Honestly the crash bar thing is way overrated IMO. The foam piece that goes over it still blocks everything, and even if you remove that the ammount of air is limited by the opening on the grill, which is smaller than the inlet to the radiator/fmic. I think the key to keeping cool is fresh air to the radiator/condensor. I could have easily go 8-10" wider, but I wanted the fresh air to filter condenser and radiator.

Basically none. FMIC touches the end tanks of the condensor. So between the fins maybe 1/2" if that. Same as the old setup. Remove the lower portion of the cross bar just allowed me to go 4.5" thick instead of 3.5" in that position.

I wanted to cut the frame bar out (C notch style) and move the IC all the way forward to the frame bar location, almost up to the license plate..Basically leaving the stock width gap between the IC and the condenser.. (bottom feeder)
I sold the car so won't be doing it now.

I thought about that, but then IC has to be kicked way back for the upper inlet, and front/lower then gets in the way off the grill. I tried a ton of different mounting options and I'm happy with this. If it went father forward the 4" pipe and hood would not work.

looks awesome. really interested to see how this works out with IATs, etc. I've always been curious if my stock ECS intercooler is holding me back at ~900whp
did you say somewhere you had a stock ECS style intercooler in there before?

Im not sure if I would expect much change in iat especially with meth but I bet you gained some power. Considering that people at that kind of hp with a Procharger gain atleast 100 swapping to a 4.5in core. looks nice man! Who did you get the core from?

Bell core. Ordered to my spec from Bell.
IATs crusiing around at 3-4F over ambient. No difference in cooling so far but it has only been 105-106 at most. IATs under boost are -20F or so after a 2nd-3rd pull. No different that before.

E85 has zero effect on IATs.
Just hoping for more power. Will wait and see. Was logging Saturday morning and before/after no noticeable difference. ~90F outside and end of 3rd gear pull was ~68-70F. Before it was 180-190mph in 5th would creep up to 120-130F. So if it stays before 100 for a 1/2 mile I would be happy, but who knows until I try it.
Looking back, I might have just saved the $1000 it cost, but ohh well.

Unreal, how about doing some tests without methanol? Wonder if you are spraying so much you a reaching saturation point and thus getting no added cooling? Be nice to see what the intercooler is doing for cooling rather than both of and the meth...
