It's also gets rid of heat soak problems. I spray on my Whipple and I don't think I've seen anything over 120* on my IAT making 12PSI. I've kept a eye on my IAT using a Ultra Gauge.

With that I didn't start loosing any HP on the big end and I see that as a gain.
What were the iats without the meth?

I have seen them up around 150 with 6psi boost.. After meth IAT's around 80 staging and then by end of run might hit 120 on a hot day but I also pulleyed down same time I added meth so this was @ 12psi boost and not 6psi. Different subject but now with meth and superchiller IAT's haven't topped 80 @ end of run.

We'll that's encouraging. I see the same 150 plus. I ordered a super chiller, still waiting for it to be shipped. Did you put chiller and meth on at the same time ? Or did you do one and it wasn't enough so added the other ?

Meth 1st and then later did the Super Chiller.. With both on a 70-80f day @ the track my cars IATs will be around 120 between rounds when I crank it. After a few minutes idling they will drop to around 40f and after a good burnout, staging, and 1/4 mile run they have not gone above 80 so far. Meth kept me around 120 and with both I stay around 80f.

That's crazy. I wonder how the iats would be if you pushed the blower to 16 psi?

Good question. My info is @ 12psi and no cam. Will soon see how it works with the added hp from recent cam upgrade.

I think the cam will help with lowering the boost but once you cross the threshold the iats get silly high. Question is what is the magic number.

But, the question, regarding meth with Maggie, remains....


This is my proof and results. Seeing how this thread started with lack of knowledge suggested that meth can not be safe, i rather not go into details on how it IS tuned properly Here at Lethal, i would not make a statement if i did not have some real world info to back it up. I think thats the only way to stay credible

Correct, on the dyno with the cam added the boost dropped, but the gain of the cam far out weighed the loss in boost..... By 100rwhp But, the cam did add in its own heat with now having more fuel being burnt to make that extra rwhp. Excellant info given by SMOKEDSS.

Not sure if anyone has run more than 15-16psi with a chiller yet. Of so, maybe they can chime in.

I understand what you're saying and not questioning your credibility. I appreciate your taking the time to educate I just have a hard time adding something to my car if I don't understand how it works. On a Maggie, 120 degree IAT's are OK in 95 degree weather. 120 degree IAT's in 45 degree weather would indicate the meth wasn't working and timing should be pulled starting well before the IAT's hit 120. Yes? No?

thats correct. also with 120* temps at anytime, timing is being pulled. this is why SMOKEDSS runs the chiller also
