I am assuming you are using the "shut-off" solenoid on the nozzle in the picture? If not, siphoning could be taking place, especially during deceleration.

 

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 thought you might have but I wanted to make sure. The next thing would be to reset your e-shaft profile.

 

The brake pedal dance?
My car runs badly until it builds trims....

 

Yep. May not help but it won't hurt to do it.

 

when you say you re building trims of 7 at what load, rpm and speed does this occur

Hey guys. Are you buying your water/meth anywhere other than Snow??

 

Walgreen's. Sometimes the gas station. Wherever it is on sale.

 

Okay, i'll bite. Where in Walgreens??

 

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.

 

I use the cheap stuff. I think its 5% - 10% or so (depending on where you live), premixed with distilled.
$1.30 a gallon.

 

Here I am buying RC Car fuel for 28 dollars....
77% methanol, 33% nitromethane.



/I want M5 from VP Racing fuels.

 

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).

 

That's it, I can go to BubaLou's for Psycho sauce to inject....

 

If gas goes much higher I may convert to methanol.....

 

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.....

 

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.
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?

 

MM why are you not watching Top Gear?

 

1) I'm busy stripping the clear coat off of my rims and polishing them
2) I DVR it for later viewing
3) I already got it on BitTorrent

 

new wheels? or same wheels?

 

Oh snap!

 

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.

 

i just wanna express how much i love the interwebs

 

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.
olddragger

 

So you needed to cool the exhaust from the blow-torch/hair dryer?


Florida is hot, and humid 97/97 is the normal these days.

If I have been on it, about 10 to 30 degrees below ambient; that's pretty good considering you and I both have been running methanol.

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