ECS 1500 and HIGH IAT Temps

It's the stock pulleys that came with the basic kit. 3.33" I believe? I was at 7-8 psi at the top Saturday. That is with restrictor in place.

What was the outside temp like?

[TornadoSS]

69 degrees DA of 2660'

OK, I logged (HP Tuners Scanner) the temps from a cold engine, scanned key on engine off (no start since Saturday) Here is what I got -

Intake Air Temp (SAE) 54 degrees
Ambient Air Temp (SAE) 45 degrees
Engine Coolant temp (SAE) 50 degrees
Radio Display temp 51 degrees

Thanks for helping me out guys!

Those numbers are fine.

I agree, there doesn't appear to be any huge discrepancies between these sensors.

Looks like maybe I need to try some different staging lane tactics and try again soon.

[grocerygetter]

Agreed...looks fine. Try what I said. Keep the car as cool as possible and let it cool down between passes. Do your burnout and Go stage first beam. I let the other guy stage second beam first by just a split second, that way I'm not sitting on the rpm waiting for the lights to drop...that makes heat too.

Make sure engine fans are running at a lower temp than factory. Put in a cooler thermostat maybe, will help if fans are running.

What were your 1/4 mile times?

[TornadoSS]

Fans are tuned to come on lower than stock, but that was with the na tune, can't remember if we messed with them after the blower tune. I'll look into that further. 160 tstat installed. I am looking at adding the manual fan control harness if I can figure a way to run it on accessory switch, shouldn't be too hard.

Lol my first pass was 11.91@120 60' - 1.83. It fell on its face that pass because it dead hooked, tires and rxt clutch, lol I only launched at 4000. Leaving at 5000 helped but didn't improve times with the heat issue. The other runs were 12.0's@118.
I just need to start addressing one issue at a time and get that et down.
I'm just new to the centri so I was just looking for what is normal and what's not normal as far as temps go.

I have a pre blower Mr Freeze meth kit, using a fairly small shot, and still see 160 IAT at the end of a 1/4 mile pass on a 60 degree day. Blower is overspinning just a touch at the very top of each gear. I am seeing 13.5 psi at 6250 Rpms. I think once you start spinning these blowers near their max they make Lot of heat, and the ECS intercooler doesn't help a lot when the post blower temps are really high.

Although the pre blower water meth doesn't help the IAT a ton, it does add cylinder cooling and octane so you can run higher boost, leaner mix and more timing even with the high IAT's.

I also cut a hole on the front of my plastic inner fender to help let air in and I think that helps. Any airflow helps.

I have a manual fan override switch/harness on the way. I'm hoping I can use it to help keep the car cooler in the staging lanes. This is just one step of many, I think, in the right direction. A meth kit is planned just need to make some money first....lol

I see the high IATs at the end of the run because I'm pushing the blower at and a hair past it's max. Never saw high IAT's at the beginning of the run. They always start low and climb. Might see them drop a little after a shift, then climb back up as the Rpms go up. I'm guessing you had the blower and intercooler really heat soaked. Fans running should help. Minimize the idle time, make sure the A/C and the defroster is off as they both put heat into the condenser up front. Consider making a nice size hole or removing some of the DS inner plastic fender at the front inside of the wheel. Lets cool air in right in front of the air cleaner. I think that has helped me the most.

Thanks for that info! I also left my ADM air scoop in place hoping that would help get fresh air into the engine bay also. Can't hurt.
