Water meth

[2010_camaro]

Ok so I'm fighting bad intake temp issues.
Twin turbo built LQ9 ls3 heads Holley sniper intake custom air to air intercooler. 25lb of boost full E85
Currently running snow performance meth kit with dual #6 nozzles. Biggest they offer.
Correctly running 100% methanol.
At the track on trans brake I'm seeing 95* iats at the end of the pass I'm seeing 197*.
Snow says its because im not running their boost juice. Seems more like they want me to buy more stuff from them.

Am I actually better off dropping to a 50/50 mix or keep on the 100% methanol?

I want to avoid air to water because I street drive this car alot.

Water cools better, I run boost juice...

A/W is better in every way, even street driving. Just run water in the tank and you're golden for street driving.

Sounds like you need a more efficient A/A intercooler though. I'm seeing like 120 at the end of the 1/8

what happened to your other thread? You are going down the wrong path, mathanol isnt goign to fix this , you obviously arent running enough intercooler. Lets see what you currently have.

I told you in your last thread , when heat turns water into steam the molecules expand over a 1000 times. That reaction reduces heat tremendously. Meth is only to add fuel and reduce predetonation...

[davidscamaro]

Meth no make heat go bye bye,

Water make heat go bye bye

Just a little joke ^

Just trying to say meth is only a fuel , it would be the same logic that increasing your fuel injectors output will cool down your boost , and we all know that does not work

Okay so methanol shines during combustion. Yes your iats may be high but the methanol is doing its job. Plus you're not using enough methanol to drop iat significantly.

If I was in your shoes, I'd run 15lbs worth of nozzle at a minimum and pull some fuel from your table

Also is your iat sensor after the nozzle to actually show the drop? But I'd for sure stick with 100% methanol

Water is good at cooling things and putting fire out, so while it will lower IAT's, massively reduce knock, allow more compression, boost and timing on lower octane fuels. It does all of this at the cost of horsepower because it's neutering the combustion process. That is useful for getting an unstreetable race engine to be usable on the street with pump gas, when you don't need to make maximum power and don't want to use race gas all the time.

Whereas methanol both cools very well, and is a race fuel that is highly flammable. So it it will lower IAT's, massively reduce knock, allow more compression, boost and timing on lower octane fuels. It's does this all while helping you increase power. Even on E85 cars that don't have a hint of knock, we still gain power from the cooling effects.

Better turbos, better intercooling, better engineering, better design/ application of everything should all be done before just dumping loads of meth into an engine to bandaid these shortcomings. Meth sprayed before the throttle body into an LS3 shape intake manifold mostly goes into Cyl 7&8 and very little into #1&2.

tested and proved.

Yep, didn't that screw you pretty bad?

I've seen that soooo bad that turning the meth completely off gains a bunch of power. The car is basically running really well off the front 6cyl. and the rear two and dragging you way down.

We spray about 2 feet before the throttle body. But I have no idea about the dispersing into each cylinder.we also spray from the middle of the tube and not the side.

I am going to guess that OP doesnt have an intercooler at all.

OP has an intercooler......

I pulled the intercooler and ran a test pipe. Intake temps dropped significantly in a pull. I'm either out flowing the intercooler or something inside it is clogged up. I cant remember the CFM the core was rated for.
