Yes, I do have the solenoid, it's on the firewall beside the windshield washer tank.
Update: look to the immediate left of the tape measure in my picture, the solenoid can be seen in the picture.....
I also have the 2.5 gallon tank in the trunk.....

I think he's talking about how some windshield washer fluids contain 50% methanol (HEET makes one too that I think they sell at Walgreens). You can also use HEET gas-line antifreeze (I think that stuff is 99% methanol) and mix it with distilled water.

Complete waste of money.
Until you are running 12:1 compression and 20+ PSI of boost with 20° or more of advance, you don't need anything like that.
The "fuel value" of the methanol is a complete waste - you are better off just tuning a bit more rich.
The cooling value *might* be useful since you guys are using a BBQ to compress your air, but probably not.
The water is really doing most of the work. The meth is added benefit.
Any power increases you see above what water alone gives you could be created by just running more fuel (and timing).

About the heat on a Pettit S/C:
Before I had methanol, I could still lay my hand on the S/C outlet after running it hard.
Can you do that with a turbo?
/don't hate me; Just stating a fact.....

Can you lay your hand on your exhaust manifold? No?
Same goes for the hot side of the turbo.
Oh, wait. I can lay my hand on that too. Copper-impregnated heat cloth FTW.
It all depends on where you live, though.
I can't even touch Phil's hood after a hard run.
BTW - the air coming out of my intercooler is ambient. How about yours?

new wheels? or same wheels?

Same. They were just getting a bit ratty, so I stripped them and polished them.
They look brand new now.
I also had the tires flipped (since I can't rotate them with the staggered fitment).
Well, he didn't understand the fundamentals of what he was insinuating, so I redirected him.
Fact is, the output of the twin-screw is an order of magnitude hotter than the turbo and it only goes up as the RPMs rise, unlike the turbo where it stays the same no matter what.
Then, the A/W gets soaked and heats it even more in the mid-range, so you need the water/meth just to get back to where you started.

well at least now with the w/m system we can go below ambiet if we want. matter of fact if anyone with a spercharger wanted to, you could set up a system where an intercooler would not be needed---period.
Phil was getting that hot huh? damn.

On the cold side? Yes. Easily. It only gets up to whatever the temp is in the engine bay. That is the equivalent part to your S/C outlet plenum.

The really fun thing is we can argue over turbo vs S/C for years.....
/and never solve a thing.
