Meth kits are not just benificial for adding more boost it also helps with heat soak, problematic with a 112. Personally I've got a 3.3L whipple waiting to go in. While My Iat Temps aren't going to be a problem with a whipple, I still want to go with a Killer Chiller for when I do push it. I have major plans for my build and a KC or even meth kit if I choose instead, will fit right in.
If I had a maggie I'd probably still look into something to keep IATs down regardless.
He's talking about only doing street driving, though. Do they get heat soaked from a single WOT blast? Or is the included intercooler not that great?
Meth is good for IAT and an octane boost, so you can run a lot more timing. The timing thing is a big issue because your screwed if the Meth fails you might get knock. So I wont get into that unless the OP (or someone else) asks about it.
Don't put too much stock into the octane numbers of Meth. Pure Meth is over 100 octane. But you have to take into account that most people don't run 100% Meth, then you need to figure how much of that is mixed with your fuel. In short, you will be running a higher octane (for more boost?timing) but not too many people know what their octane rating really is.
Alky control has the best rep hands down. If I remember correctly, their kit was around $500. That said, I have a cooling mist kit that cost me about $300. It works off boost and I can control how much I'm spraying as boost increases. I guess I've had it for two years. No issues with the kit. Only problem was a wire got loose, my fault.
Heat soak: When I first got the Maggie, my IATs were as just high sitting in traffic as they were at the track, in the 140s. And it's worse if you let the car sit a while and start it up again. Without Meth, the temp will not drop much on a hot day. Driving through the infield at Pocono, after two very long straights (long periods in boost) I looked at my gauge to see my IAT at 114. This was on an 80+ day.
