Hot temps hurt blowers, period. Both air-air systems like yours and also water-air systems like the roots blowers have. I've been at the dragstrip on a hot day with my supercharger and talked to a modded Hellcat guy (water-air) and he told me that he was down by 8mph that day. Another hot day, I saw an air-air setup on a built motor with meth injection, and he ran 10.3, then few months later when the air was cooler he ran in the 9s. Meaning, even with benefits over your current setup (either water intercooler or methanol injection), heat still produced lower performance.
My suggestion when you race is to temporarily pull the front plate and bracket off, like the Chevy track prep manual says for the ZL1. One thing that you can do to lower MAT a little is to run the coolant at a lower temp like KingLT1 did on his own car in the thread he's mentioning. Using a lower temp thermostat and adjusting fan settings accordingly. I suggest a Katech 160 or 174 because of their quality, and definitely NOT the Mishimoto thermostat. As far as meth injection for cooling, I think that a safer setup would be a single-nozzle water-meth injection system with windshield solvent like laynlo15 was using on his blower for awhile. Reducing the amount of meth to ~35% means less change to your tune, and therefore less chance of blowing up if pump fails/tank runs dry. The high water content is good for cooling too. The concerns about fuel distribution in a manifold designed for dry flow IMO would be lower with a fairly modest amount of meth going in (like my proposed scenario) than with 2 or 3 nozzles worth of 100% meth like some guys are using in the charge tube. |

Thats all good info. Thank you. The thermostat is a good idea. I have it on the TODO list. I should move it up on the priority list. Ill have to read up more on water/meth inj to get a better idea of what i would need to do, but running lower meth % as you mention is a helpful suggestion. It sounds like a fun project, but not sure i want to go there yet. Im curious how the added humidity with the addl water being injected will affect combustion vs the cooling it (water + meth) can provide. Since im trying to stick to a no dyno self-tune that sounds challenging.... but fun. I also like 1LEornothing's suggestion of spraying distilled water on the intercooler. I think the air-air ic hidden behind so much stuff in the front end is not ideal. Was trying to think of a way to chill the intercooler. I may play around with using a meth inj kit to trigger spraying distilled water on the ic. I would think that a meth kit would contain all the appropriate electronics and hardware to trigger a pump or solenoid to spray water on an ic. May have to fab up some brackets and figure out what can spray an adequate volume of water. Not sure a meth nozzle designed for spraying an intake tract would work like that. If it doesnt work out then maybe ill be able to use the same kit for its original purpose. I drive 99% on the street. I dont need fast track times other than for bragging rights and validation of the tune. Im more concerned about doing hard pulls on the street and damaging the motor in the heat.

Right. Good point. Right up there with dripping your A/C condensation on the track for the next guy. I wondered why that wasnt common

If you want to spray the intercooler, CO2 is a dry option that will cool better than water and not get the track wet.

A quick back story. While I’m true to my Chevy roots, I help out a friend when we go to the track together and also my cousin. My friend is running a 440 Coronet (100% street trim. 10.14@135) with a 118 rear mount. Car runs good. I help him out with tuning and we go back and forth on various ideas, especially at the track. He’s battling IAT’s too and we’re 50/50 water meth. I almost called him after reading your post and it hit me. Wait, that water has to go someplace. My cousins car is a SBF Mustang with Procharger. (4.56 in the 1/8th) We are always talking about IAT’s, ice box changes, intake plumbing changes, etc. Anyway, for all of the years we’ve been to the track together, spraying the intercooler was never a thought. Keep those ideas coming. You may unknowingly help us out too.

You'll pull way more heat off the IC evaporating water than hosing it down. (970 BTU/LB evaporating vs. 1 BTU/LB running water over it.) Set it up on a timer (ex. 2 on/2 off), or maybe a boost switch, so you don't overspray the IC and drip. Even if the mist didn't quite hit the IC, cooling the air in front of it will drop the air temp before it goes through. I'm sure you'd have to play with it like carb jets depending on temp and humidity to get/keep the right balance though.

One of the guys from Procharger had a massive thread all about this a few years ago.
Wish I remembered his name. The thread was interesting. He did make some pretty big claims though...

Im interested in the results too. My car budget is low right now, or id do it. Im interested in this approach because my fueling is spot on right now, and i dont want to mess with it. Im sure spraying in the actual intake stream prob cools better, but then im basically fueling with meth.... and i want to avoid that.

A non-related question, do you have any videos of your car with the current setup?

Has anyone used a different intercooler setup? Treadstone, Garrett, or Bell? I see a Treadstone TRV259 SERIES INTERCOOLER 1300HP that looks like a Procharger stage 2 intercooler and has about the same footprint. Anyone use one of these and have better results than the Procharger one?

One of those companies probably provides Procharger with their cores. Garrett is the most efficient core you can get |
