Drastically lowering IAT....

Is it a separate table that pull solely off rise in AIT's or the Burst Knock AIT Multiplier table that based off the name, appears to just pull the timing quicker in the event of knock. I don't tune, just like to understand whats going on with my $.

What kind of boost level, supercharger brand, RWHP, stock cubes or stroked, etc is Smoke 1LT's Camaro? Has anyone had a chiller installed on 17 psi at or near 700 RWHP?

Smokes is a LLT v6 with only 4-5# boost currently until he receives the overdrive pulley.

Turbo99 has mid 600 rwhp with his, and no matter how high of boost the system is more effective at lowering IAT's below ambient than any other type of HE, intercooler, or ice bucket system.

You are correct on the timing tables....you have a good understanding for not being a tuner! More than even some "tuners".

Still looking for a ZL1 that wants a free install!!!

click on the PDF file below what a stock IAT table looks like. Your stock tune starts to pull tuning 86*
Idle at a light for a couple minutes and you'll be in the 120's with bolt ons. Tip into boost, and you'll be at 150* in no time. That's why your car's are a dog when you stomp on it from a light before a tune.

These chillers make life easy on us tuners and make your cars better!

Question....what about the MAF? If it is still reading 100 degree air temp (low density air) what over rides the MAF reading to pull timing when you are cooling after the MAF? Would it be benficial to cool the air before the MAFalso?

[SC2150]

Have had no issues with the MAF, and the IAT's are read post intercooler so that is accurate for the ECU. Good question though.

With the front mounts the MAF is chilled also, but not the top mounts due to the location of the IC.

On the ZL1 IAT2 determines timing. IAT1 assists with the air mass calculation so it doesn't play much of a part in the ECM determining the timing selection.

Thx as always Roket!

How, if done, was the install on a camaro with a e-force, considering the coolant placement parts for the SC's system?

If IAT sensor is installed after the IC on the Maggies, the 2 wires that origionally read the IAT off the MAF have been relocated - so no longer seen by the MAF sensor. (part of the TVS2300 install instructions..... and probably Whipple & Eforce)

If still reading off the MAF, the real IATs inside the supercharger after the IC are predicted #s from what I've checked. I can't understand how they can be predicted accurately without accounting for possible high and low conditions, and then tuning based on worst senario - pulling timing when AITs aren't bad too.

On the other hand, it seems if the sensor relocate is done and AIT #s are instantly higher due to real #s, timing would be possibly pulled prematurely if tables aren't adjusted.... effectively not making the best use of the accurate #s off the relocated AIT sensor.

Our camaro systems are flexable to allow for all the top mounts, ZL1, Maggie, Whipple, Lysholm, and KB instead of a specific system for each application. It comes with pre-formed hoses and enough lines and fittings. It also has no interference from the fog/driving lights.

The chiller sounds really I'm curious about road race setup. I don't really race but take it to the track for a few 20 minute hard driving sessions.

I've read in this thread that a separate 12v compressor would be the way to go. But I'm not exactly sure I understand what that means. Does it run directly off the battery? If so, would it eventually drain the battery? Or is the alternator able to keep it charged while in use?

[SC2150]

The 12v unit is a heavy draw and adds a bit of weight. We would only reccomned it for a track only application due to the cost, etc.

We need to put one on your car for you to give feedback. The system as is works well as your not dependant on ambient air temps to cool, and even though the compressor disengages at WOT it will re-engage when you lift for corners etc, and with a 1/2 gal or so coolant resivoir there is enough reserve chilled coolant to still be effective whe in competition mode as the cabin AC is truned off and you also dont have the water dripping from the humidity removed when running the cabin AC.

Lets talk.....need to have one on a road track car car for demonstration anyway.
