Drastically lowering IAT....

[SC2150]

He has dedicated DAYS to this.....really valuable, and pretty unbiased as were not part of any of the testing.

A few things we have considered that would help the1/4 mile effectivness:

When the chiller is off, the valve opens so the coolant is going through the front mounted heat exchanger and it is working in reverse....heating the coolant UP to the ambient temp. We can have an additional switch to override the valve and keep it a closed chiller circulation so the temps will stay cool much longer...through the entire run but we are worried if it isn't shut off after the dragstrip and a customer is driving around w/the chiller off....they would have even higher temps. Just an option

So far none of the testing has been tuned to optimize....were only basing all this on preventing spark knock and timing pulled. Tuned to use the cooling power woul/should yield 40-50 plus more RWHP as you can run more timing, the air is denser so carries more oxygen, and add the fuel it will crave to an optimin A/F ratio and you mat see even more gains. Remeber, heat is the reason the FI tunes have to be so conservative....take away that danger and you can tune for the IAT temps.

Chiller kept the IAT's at a constant low temp so they were going to see when the tuner arrived what they could safely tweak it to as far as gains. Every test so far has exceeded our expectations and doing this in front of the world was a little ballsy if it had not worked out as planned.

Jeremy should update with his notes later this evening.

Middle East desert area's were ready to take orders so you can get this on over there for some real acid tests.

This literally just keeps getting better and better. If this is a dream, please don't wake me up!!!

Just need to get funded now to properly be able to market it and meet the demand. Have over 20 cool products we have developed in-house and only have a few on the market due to the costs involved. :thumbsup

Anybody know how to post SCT data logs, It put them in a excel style and they are LONG

past my bedtime, gonna keep me in suspense till tomorrow..lol

I ok well I got the data off we needed, I tried to do a graph and all that but I am tired and not gonna do it now. So the dyno sheets I emailed to myself from the shop didn't work so I will go off of memory for the numbers there.

First off the A/C does kick off at WOT but comes back on around 4500RPM(we could see a dip in the dyno sheet. So for ALL the Chiller on tests we let it chill for 5 minutes between runs and just before we went WOT we turned off the A/C. Same 5 minutes were given for cool down for Chiller OFF.

Chiller OFF Data

101* AMBIENT
1st pull IAT start at 104*F end at 122*F car made 568

2nd pull IAT starts at 114*F end at 140*F car made 55? had a small amout of KR (.3)

3rd pull IAT starts at 125*F end at 145*F car made 54? had alittle more KR (.9)


Chiller ON

107* AMBIENT
1st pull IAT starts at 64*F ends at 113*F car made 56?

2nd Pull IAT starts at 66*F ends at 116*F car made 56?

3rd pull IAT starts at 66*F ends at 116*F car made 56?

Did a pulley change 3.6 to a 3.4 and went from 6psi to 7 psi and made 596 and the torque can't remember but it went up almost 50ftlbs. IAT were the same as the other runs with the chiller on.

I didn't tune for the chiller, we were pressed for time as they had 2 other cars that needed tuning and I was on the dyno most of the day doing 8-10 pulls. The tuner though we could get another 1-2 degrees of timing with IAT where they were with the chiller on but since we didn't have time to test I choose to stay where I was and be safer at the same power level. I think if your IATs are higher than 140*F you may get some HP out of this deal and be alot safer, but my car at 6-7PSI doesn't produce alot of heat.

I hope everyone is ok with the test as you can't please everyone but I did my best to keep a even playing field but temps came up as the day went on and engine coolant temps are what they are when we hit the go pedal. I will try to get some logs for the 1/4 mile but it isn't going to change any from what I have already done around here on the road and the dyno actually proved to heat up the car more than a 0-120mph run.

U can print then and then scan as a picture ?

[Turbo99]

I just got the important data and put it on paper and type on here, there is so much data on the things it would be 3 pages long and it was only a 2 minute log each but it logs a data point like every tenth of a second or so. Most were over 1000 lines long as it has from 1st through 4th gear on it then as we lifted another 10seconds before I got them stopped atleast.

The data is there, I have ZERO to gain from this so the numbers are what they are, It actually did better than I thought with the actual IATs I didn't think it would drop them 40+ degrees.

I want this on my car.

just want to clarify, you cooled with chiller , then turned off chiller b4 dyno run{ just like you would do staging at tree} then after run , turned chiller back on{ just like you would do after completing track run} for 5 minutes ...cooled down for 5 minutes an ran again...sounds perfect for 10-11 second pass. summary is it lowered iats approx 40 degrees...anything i am incorrect about?..thanks..soon it will be time for track test, any idea when you may run 1/4 and log iats there...great job jeremy...exactly what i,m looking for, something to drop my 9lbs boost iat from 185 down to somewhere around 140-150..that is acceptable..tracy wanted to clarify. when chiller is on , he is totally bypassed? there is no flow thru he? correct...so during runs i would assume that he is totally ambient temps as it is not flowing or aborbing heat from the sc..and actually daily driving you really would not need to run chiller...so this is def more a track setup to cool quickly ...noit like it would really be needed on a dd...seems consisteant starting out around 65,, and climbed about 50 degrees per run, i,m sure more boost /more heat, so even if it climbs from 66 to 150 thats a 90 degree rise , that should give me a safe cushion...way better then 185 to 220

Your summary is correct.

I plan to run either saturady or next wednesday......weather permitting.

You are correct that when the chiller is ON the heat exchanger is totally bypassed, after it has chilled and got the I/C water to to 55*F or less it has enought there that it holds the cool temp just as good as if it were still on for the time it takes to do a 1/4 mile pass(approx. 30 seconds by the the time you stage the lights and leave). I was very surprised to see that compressor kick back on and stay on from about 4k rpm on, it didn't effrect the number down low but when it kicked on up high you could see a dip (5-10hp) IIRC.

I like the fact that it runs with my A/C on for DD because my runs done the raod ALL day in 100+ weather with 55-65* IATs instead of 110* IAT, I know the dyno didn't show any gain in HP but the car feels snappier than it did, not alot but it feels like it gets through the gears alittle faster than before the chiller.

I would not be so sure that it won't get you more cooling than 40*f on something hotter as it seems the 40-50* mark on my car is about the limit for how cool it can get the IATs, then again it may only get you 40-50*F to, that is one of the things that will differ from car to car and SC brand to brand.

[mikepage0007]

sounds good, so really the he is only used by you when you actually turn chiller off for 1/4 mile run.. otherwise there would be no reason to have the he...since it never cirulates other then track use ...seems kind of humorous...i almost would not be surpised if the sc companies would not try to steal this and use it in there systems always, especially if you were to try and go up in boost...wonder how it would work in a 16 lb boosted car...i think ss should incorporate this along with his ice bucket and he could probably runn under 100 degrees iat...lol

[Turbo99]

Not really, don't forget winter, heater on means no compressor on so you use the HE in the winter.

Anyone wanting this installed on a Maggie or E-Force were taking orders for slots to install. We need your car for app 5-7 days max (should be far less as Jeremy's allowed us to perfect the system).

George gets the first KB insatllation as tha deal was made before.

PM me to set up and schedule yours in.
