an ice bag did nothing for intake air temps by the 330' mark.

i wasn't logging my passes so i don't have a clue what my temps were
If I'm weird and everyone else is weird, does that make me normal?

Clyde you ran a 2.4 pulley with no alchy? I can definitely feel when my sc gets hot, Ill see 7-8psi when its like 60 degrees or below but in this heat I barely see 5psi.
My set up maxed out at 7.5 PSI. MAT never got over 150-160 while under power. I tried using alky but it didnt help any. I did however use it on the street for normal driving because it made me feel a little better. If I were to rebuild the S/C engine I would deffinately put the alcohol system back in the car.
70-75* temps here...
2.6" charger pulley, and a OS crank pulley (2.8 charger pulley ran the 13.7). M4 Nozzle, 100-125 PSI pump.
striate water, from what i read, it is better at taking away heat.
I'm TELLING you, if you want to be quick with this setup, water injection is a MUST

Along with modifying the program. I was never able to while I had the S/C. If I can pull the money out of my ass I want to try it again. I know I could have pulled of a sub 14 sec pass with some program work.
Chris, did you do any internal work to the engine, or was it all stock?
Nothing was done to it, it was a bone stock 13X K mile Z24, not even the 95 LO cams. hell the water pump was OE. other than the pulley setup, and exhaust, the Tuning I had (Took Ron's tune for Wade, and "played" with it.) really took it to the "next" level. but still, i had no wide band, just looked all the info on the scan tool, and KR. went from there.
IMO the best set up would be, HO cams, (or W41's) OS crank, 2.8 charger, water injection, 2.3 oiling, Flat top pistons, and a nice long tube 4-1 header.
that would be what...230 Hp

you always mention something with the OE water pump, i know they go easily but are you claiming that a bad or old one actually requires more power to spin it or something?
no, its just another throw back to 03 when every Quad 4 was @!#$ becasue of how often the pump went out.
and for everything that the car did, and how many times it was raced, i never had to do ANYTHING to the motor.

HO cams, ported head, 2.4" pulley, 2.3 oil pump, 10:1 CR, OBX 4-1 header, exhaust dump, stock program (reflash), and 310 injectors came out to 226.5 to the wheels at 6500 RPM. Needed a lot of tune work, also didnt help that the S/C had been broken and welded back up.
meant to say, 2.6" charger pulley,
(thats at the max of rotor speed.)
ya..... 310 injectors were maxed out with the stock pulley and HO cams ALONE, never mind everything else....

hot temps outside? alcohol/methanol/water injection will make that SC nice n cool.
coming soon hopefully. also, i do take out the stereo equipment when i take it to the track. I managed to do a 2.3 60" with the rims too

it helped out alot with me , the s/c case would cool , and was able to keep it cool from the burn out box to the end of the pass , and never went over 100 degrees
if i didnt ice the s/c down i would see the temps climb once i left the starting line
I got my coolingmist kit in now, sc was very cool after running it realy hard
And the 2.6 pulley sure does make it whine.
water/meth injection was a great mod for my car when it was s/c'd. (m4 nozzle)

Yeah, 15.0 @ 96. Hot day, only went down the strip twice. Couldn't get traction. Next weekend, got drag radials, again only went down twice, couldn't get the launch right, ran 15.4 @ 92 or some @!#$. Only saw 5 PSI. At night I see 9-10 PSI along significant power bump.
So I turbo'd. @!#$ this non-intercoolability of the MP45. Methanol didn't even do anything on hot days. Worked great at night, but it just can't keep up with the massive heat generated by the supercharger. Ideally we would need to spray post-blower for maximum cooling effects. Spraying before the blower makes it try to cool down the supercharger, and it just can't overcome that.

I should have some times real soon.
As for meth not working on hot days. Well you aren't using a big enough jet then. It helps, day or night.
FU Tuning
Of course it helps, if it was sprayed post-blower. Can't really do that on this setup. On turbocharged cars and others with remote mounted blowers it helps immensely because you want to cool down the charge air, not the supercharger. By spraying it before the blower, it just can't overcome the heat generated by the unit itself.
I was using an M5 nozzle. Worked GREAT at night. My temperatures went down the longer the pull was.... during the day, my IATs couldn't be quenched.

I'm running it. I'm in Florida with some of the hottest temps. MY IAT's will only climb roughly 6 degree's from where they are in a run. This is day or night. This is using a TB spacer.
I do not know what nozzle I'm using. I wish they were clearly marked.
FU Tuning
Yeah, that's really weird. It could be an 80*+ day out, and my IAT's were rarely more than 10* above normal. I was running the DevilsOwn kits through an M5 nozzle in a TB spacer. 50% pure methanol, 50% distilled water.
