Boost weather goes bye bye :angrys00ls:

Car gets warm quick when it starts getting close to 80. I got one pull in before the car pulled 8 degrees of timing......:trump:

Need a killer chiller

Do you have a post intercooler temp reading? I was seeing 112 after driving around 100 miles this afternoon

Meth is a bandaid. Car is on E85. It is the IAT's post blower. Onboard readings show 125 degrees idling in 85 degree weather, but my datalog shows actually 140. The car will start pulling timing at 140.....

I have a big 3.5" heat exchanger sitting in my garage that I'm finding time to put it....the killer chiller is the ultimate plan, but I'll try to combat it for now. I'm working on trying to isolate my filter a little better too from the engine bay heat to delay the rise from sucking hairdryer temperature heat. The benefit we have here is......March/April and Oct/Nov.....

Sounds complicated. I'll hop in and beat the fuck out of car and I don't even have any gauges, not even oil psi :lmao:

Meth is not a bandaid.
Sure it is. I compare it to running a boost a pump on a system that actually needs more fuel.

If your meth "pump" decides to quit. You go lean, and then bad things happen. It has great benefits and cools the intake charge excellent, but my paranoia would always be worrying. There are guys that use it to make big power on pump gas.

No thats not how you setup or use meth.....

You use meth as a failsafe to prevent bad shit from happening like pulling timing in this case NOT tune the car on meth and ADD timing.

In that case then yes meth would be a bandaid. Without the drug in this case the meth the engine would not be happy and likely eventually become suicidal.

LOL.

Class dismissed.

I really enjoyed having no gauges in my Cobra. I’m sure if I did I would have just worried more often about fuel pressure and wideband readings. Hell I just figured the pulley combo was supposed to be about 20psi, never took a boost reading :jg:

At idle it would be high it should drop when driving, if you watch the sensor when you get down on it it should drop a bit at first with the rush of outside air then start rising fast as the blower heats up, the big exchanger should help, I run a 7 gallon ice box the added capacity helps a bit as well

Yea it drops always, but not enough for my liking.

Once that blower gets warm it's hard to go back. The Killer Chiller uses the cars A/C to cool the coolant. Seems like the ultimate way to go to not lose timing between hits in warm weather. Guys have seen IC coolant temps down in the 30's-40's, which drastically improves the air charge post blower. It's liking driving around with a frozen blower.

killer chillers to me are more of a bandaid than meth is if we're taking votes.

So the way you describe using it, you would be ultra rich under WOT, but cooler intake charge? I'm guessing you wouldn't gain a lot of power, just safety?

I like [MENTION=917]1quick[/MENTION]'s idea of a big ass ice box personally...

It’s worth it. Especially now with the TVS. I’m going to order the remote bypass for even more cooling. The heat exchanger becomes a heating element to the killer chiller once it gets beyond 90f.

Not at all. It uses the cars own system to cool down the coolant. Ice boxes are good, but you need the cooling factor to make them work well.

The Demon uses this system, but they have been around the aftermarket for years. Allows you to hot lap the crap out of your car and always make full power.

Yea that's the issue I had with my previous cars that had PD blowers ,on the other hand I don't have this issue any more now LOL .If it was 80*+ outside it felt like car was making 100hp less. Last year at 1/4 mile track my buddies CTS-V was hitting 150-160* , 96* was the highest my car saw that day . . I logged couple passes last year at 1/2 mile event , IAT never got above 100* during a 1/2 mile pull [up to around 165mph] . It was hot and humid 80-85* outside that day too

Here is my 1/2 mile log

Most tuners will set it up so that if the AIT rises past a set temp the ecu will add fuel and pull timing. Sort of a fail safe. It isn't the best option but beats losing a pump and the ECU doing nothing.

What are you talking about? That isn't how the rest of the world uses meth kits.

The Killer Chiller works great. But like Johnny said, it can be set up better. I would say that it is a great option for a street driven car.













Water / meth injection works great when sprayed after the air is compressed. When used on a positive displacement blower and sprayed before the blower, the cooling effects are reduced. Due to the compression of the air increasing the heat of that air again. But if the air going into the blower is cooler than ambient air, it still helps.

Also, the cooling effect comes mostly from the water. If you are worried about a tune being more aggressive with the water/meth mixture, and losing the pump, just run water. You can also have it tuned to run on just water and then run a small percentage of meth with it for track days and what not. A little added insurance with the added octane. The a/f will richen a little but if the mixture isn't extreme it would still run fine and not cause issues.

Water / meth injection can be a band-aid if you are using it just to increase your lacking fuel system capacity. But it is also an option to add levels of efficiency and power potential.
