During a full acceleration run from a stop, 60F ambient, temps without meth are around 120F-130F, with meth, its 80-90F IATs at the top of 4th, around 130mph. with stock intercooler.

Hmm seems a little high I think mine were 90 degrees when it was like 80 outside and I was logging....

Ya i doubt iall be in that range if it was summer.

And to the poster on the 1st page yes the pump is gravity fed.


So iam pretty much seeing about 10F more than your logs hotrod. Prolly a pinched line.


Please stop with the failsafe comments guys, Either way i know their is a problem the failsafe would just tell me something i already know.

Its good when a fail safe tells you something is wrong, its even better if your going WOT and something goes wrong it protects you. Let us know if you figure it out!

I don't see how people are running such low IATs! I just posted this in the Vbox thread, but I will post it again. On stock intercooler + DCI and running a modest 12-13.5psi average, you will see my IATs run from about 70-125F in a qtr mile run. This is of course without meth, which would have lowered it to about 90F. With is a huge 35F or so reduction in IATs. And this was around 50F ambient temps. IATs would certainly be even higher at higher boost levels, and higher ambient temps.

You dont think its bc you are running a STOCK fmic? From what I have read this is a key part in lowering your IAT's. Specifically if you do back to back qtr. mile runs....or repeated high speed pulls on the interstate lol like me.

Supposedly your supposed to be right at ambient with meth and below it with meth+FMIC.


I cant see to believe that at this point but i cant rule anything out yet.

Wrong, it will drop quickly below ambient and creep rapidly on stock fmic + meth on high boost

It will flatline at ambient or below on an upgraded fmic with same conditions. I posted numerous logs showing this.

can you post that thread? I would love to do some reading on that

Here's Former_Boosted's DIY for a methanol kit install. Scroll down to the bottom of the OP and you will see the curve for for a multiple gear pull on a stock FMIC... I think. I know a stock FMIC + meth pull will have an IAT curve similar to that depending on boost level.

Here is my dyno run thread. 4th gear pull resulting in flatlined IATs.

and below is a picture of a 2-3-4 pull in maybe 80 degree ambient temps during the summer.

Listen the IAT thing is cute, but I would be more concerned with how the motor is accepting the methanol.

IGNITION LOGS are more important.

IAT is only a small piece of the puzzle.

If I started my car in the morning cold, and went to the highway, with no stops or red lights, my IAT were extremely low in comparison to sitting a bunch of redlights and daytime traffic, heat soaking the entire engine bay, doing a few pulls in the afternoon AND THEN logging IAT and Delta changes. Point being.... whats important is how the engine is taking the methanol and that is ignition.

Jon, dont take this is hating on you, I'm just pointing out to people reading the IAT are only a small piece, and that ignition values tell the ENTIRE story of how healthy the car is performing. (and how safe).

Please not feeling any hate at all. seems like useful info to me.



The thread is just to check in with other guys that are running meth with a stock FMIC and to see where their AIT's are at just to make sure if my meth flow is good.

From every one else's logs it seems that meth is flowing fine, next stop is logging ignition/timing with a friend of mines CT. If the motor is taking the meth good then iam happy.


Thanks for the advice brotha.

[GotBoost?]

i'm gonna take a log tonight to see where i stand john.. will post up later,

also keep in mind i'm running a aftermarket fmic with a dual injection setup, with 100% meth

I will post my logs with the stock intercooler and meth when I install the kit soon. I also have some video showing the temperature progression. Let me see if I can find it.

hotrod, for all the testing you do, one would think you'd test out the difference downpipes and FMIC make

I didn't test the downpipes till after the meth installation. At that point, the gains were negligible. And then when I removed them, again, not much difference in testing. Terry said without meth, I would have noticed more of a difference with the DPs. However, they clearly had quicker spool-up, throttle response, if not absolute speed.

I am still amazed how i was running 122mph+ (124.5+ Sacramento) in the coupe with stock downpipe, catback, intercooler, etc). I wish I could freeze all the car readings when it was running strong to replicate it.

What mods are on the car for this run?

JB3, DCI, 50% Meth, pass seat removal. Probably a lower map, as the car has run up to 123mph with the same mods when it was running optimally.
