I know for guys who are running a 100+ size shot it might be a pain to fill all the time. But a 35-50 shot through the blower should be good for some SOTP power and I'd think I could spray that 15 times before my bottle got weak? I'm looking for the cooling effect as well as octane increase. I'm sure at first I will spray more than I will when I get used to having it. I'd think a refill would last me a month or more. Get a 2nd bottle and I'm good for a couple months at a time.

About the pulley...I have a 2.75 and I am going to put it on soon. I was looking to meth or N2O to cool the charge and add octane to decrease the chances for detonation. If I have to decrease timing some then I will live with it. I was just worried that a 2.75 would shoot the boost into the 12-13psi range and I don't want to go that high on stock internals. I may have to tell the wife I need new heads to decrease boost levels....

 

I was @ 12-12.5 with a 3.00 on my 4.8 so there isn't a snow ***** chance in hell a 2.75 will put out that much on a cam/headers 6.0. I'd expect 9-10 if I were you.

 

Perfect!

 

Did you ever get the tune sorted out? How's the combination working so far, overall?

 

The tune still sucks. I still stall in reverse sometimes and once in awhile starting the truck takes 2 minutes of it starting and dying and surging blah blah. It does run pretty well once you get past that, other than the 45mph surge which drives me insane. The trip to the dyno in a couple weeks is to solve all these issues but I figured I may as well pulley down while I'm there, if the injectors can handle to extra hp.

 

Don't know if it helps anything, but I am running 6-7PSI on my Denali, and was just about to increase the boost a bit. (Check SIG for setup). So I have researched around 10 people's trucks and most agree that 10 PSI is safe on the stock internals, with an I/C. Mind you my application is turbo, not supercharger, so there might be a little bit less load on the crank etc. (Hope I did not invite a turbo versus s/c discussion, that wasn't my intention). However; most people also agree that the stock tranny/differentials won't hold more than 6-8PSI. I have a shiftkit, and mine is fine, but I am risking clutch/diff etc, by going more boost. I am using the Livernois Motorsports setup, and am very happy with it. The promo Escalade they are running has 12-14PSI on a larger turbo. Their engine/turbo setup is holding great, but they have had some issues with tranny/diffs.

For whatever it is worth...

I've had 2 motors, stop counting how many transmissions, and the motors where 5.3 to 6.0. 4 different cams. Helluv alot of Allen's tunes and I have never been able to stop the stallin in reverse. Of course I haven't bothered allen in a long time since I got a pretty good handle on tuning, but If you or anybody gets a handle on what the hell is so different about reverse in the tune....PLEASE let me know.

Back on subject...I with mj on this one...9.5 maybe 10. Those cubes will suck it all up. as far as meth or n2o, start with meth...it's the cheaper route right? And then add the 50 shot later or now...whenever the $ lets ya.

Like now for octane and cooling most (me inlcuded) usually go with a mix...70/30 or 60/40 even 50/50 with meth and water, but I'd assume you could up your meth count (90/10 or even 100%) with n2o shooting in. Your n2o would essentially replace your water. Plus the higher meth would cause a richer scenario...and that can't be bad with n2o running throuh there. Should be (theoretically) a great combo. Ofcourse staying at the small shot size. Going larger obviously would be it's own animal of issues.

 

Im sold on wynjammer myself with the boost that you want and custom tune it's a cool set up no intercooler. wynjammer.com

 

I've always run 100% meth. You lose some cooling (water is better at reducing the intake charge temp than meth), but gain more power from the extra meth.

 

I found gobs of 100% meth allowed me to run more timing which helped more than mixing. The increase in octane really helped I guess. Just to be ****, most people's meth tanks arn't going to be sealed and Methanol absorbs ~10% water out of the air, so technically if you run it straight then its 90/10. I buy 93% meth cause it is cheaper, that is what most people around here run in their race cars anyhow.
