I like both setups. Im leaning towards Killer Chiller. But, I'd really like to hear what you guys think of each?

PACougar

If your meth setup ever fails or has a problem, you've just blown up your engine. I'm not saying don't do it, I'm just saying there is a very real chance it could go wrong down the line, especially in a DD.

So true PACougar. Their are some really reliable methanol kits on the market with some really good fail safes. I installed one such kit on a TT C6 and it worked flawless on a daily. Boost dependent and will automatically shut off if any of the parameters fall out of place.

PACougar

Even fail safes can fail Don't get me wrong, I'd tune for one I knew was set up properly and I trusted, but it can still go wrong.

Been using meth for a while now and there is several ways to tune with it, and in the case of failure, there will be no damage done to the motor.

I primarily tuned mine for cooling. We tuned it the following way, got my baseline air fuel to 11.5 without the meth on. Turned my meth on and did another pull on the dyno. The car picked up 16rwhp and air fuel dropped to 11.0..... Then you can also play with the meth mix, the more distilled water you add to the mix, the leaner it gets and vica versa.

I've been running meh for quite awhile now and I have never had a problem with my set up. BTW I've run out of meth on the highway and on the track (5-6 times) and there is nothing wrong wih my engine.
My nozzles are post IAT sensor and only comes on after 11psi (was running 16psi). Also, I NEVER tuned for it. Cooling only. Gained 72whp after 6000rpms by holding peak power til 7000rpms.

Good Luck!

I have both a KC and meth...

Go with the meth and log. You will be fine.

I have both as well. KC is great for those red light races and around town. Then the meth is great on those hwy runs in Mexico.

Thanks for the feedback guys.

^The guy who lowered your car is finishing my meth install right now. He should be calling me any minute to say it is ready to be picked up. Like Craig, Elliott, and Dane, I am running it for cooling. I am anticipating recovering a lot of power, especially up top with the raised limiter. A 100-degree difference in IAT is serious stuff.

PACougar

When someone says tuned for meth, that normally means adding a lot of boost(turbos) and or timing. I'm pretty sure you guys didn't do either, correct me if I'm wrong. That's how you blow up a motor. Loosing a .5 point in your AFR isn't going to damage anything.

RedBullJnky

You are correct sir! I didn't add any timing.
But I will be doing so on my new build.

PACougar

Turbo's are cool, you can build in extra safety's via the wastegate.

Max.H

Good lord!

May be a dumb question: wouldn't the ECU still pull timing if the nozzle is post (downstream) IATsensor since the sensor would never see the cooler charge effected by the meth? Whereas pre IAT, the cooler charge would be recognized by the ECU and is the only way timing and power would remain intact.

Would love to comprehend the difference. Thanks!

PACougar

Yes, the ECU is always going to pull timing if the sensor claims the air is too hot. So if the only nozzle is past the sensor you won't keep the power.
