and is there such a thing as too much
thanks

Don't know figures, but my alkycontol kit is cranked up all the way

I am able to run 19deg of timing with 16psi

The main factor is how much of a lead foot you have

what afr do you run?
i ran 12psi at 12deg and it sucks

It's at around 11.0. If you spray a lot of alky, you need to move that AFR down a bit...

my car is like 10.5 its fat rich i hate that too cant wait to get some meth going alos need to get my eboost2 on as well
i just got HP tuner im been reading alot but i need a book.
i need to learn step by step but i dont want ot pay 500 bucks to do it any ideas
also lets try to stay on the meth subject

Do you mean fattening up the mixture into the 10's? Why?

Thanks

because meth doesnt burn the same as gas
i dont know the ratio off the top of my head can someone jump in with that thanks

With meth, I can only run 15 degrees of advance at only 8 PSI. The AFR reading goes from about 11.5 down to 10.5 when the meth is on.

I think one of the key factors on how much timing/boost you can run is the static compression ratio. My LS2 is still at the stock 11:1 comp ratio, so I can't run much boost/timing. Before the meth, I could only run 8 to 9 degrees of timing, and even then, it still set off the knock detector. (And ran like dog poo)

My personal opinion is you can inject A LOT of meth before it becomes too much. Maybe it'll slow down a bit from being too fat, but I like to err on the side of safety. Cheaper that way.

I'm running stock ls1 with t76 at 9psi maybe around 500whp. Running no intercooler and 12 gph nozzle. Just did a pull today its 85 degress outside and humid. My temps got up to 140 degrees during a two gear pull. Without the meth I'm sure I'd be way over 200 degrees but I'd like my temp down at 110 so I don't get timing pulled. I guess I may need to run dual nozzles.

Lets here from some more people, what gph nozzles are you guys running?

when the alky kit is turned all the way up with dual nozzles, aprox how much is really spraying, in like gph

(AIS kit)I have run three 14gal/hour at once to keep the iat down, that takes alot of pure alky every pass, so i went back to two, intake temps didnt really move much but it leaned out just over a 1/2 point afr
f1 maxed out 16psi 40deg timing ( that was on my bbc truck) little diff. from my goat
1 15gal/hour temps stay in low 60s on 90deg day

The stoich afr is much richer for meth, however most people can't or do not configure their wideband gauges to account for the meth. However the wideband sensor does know where the true stoich point is no matter what fuel mixture you are using, and when it sees stoich it will relay 14.7 to the gauge assuming you are running gasoline. In reality you really are running stoich but the afr numeric value shown on the guage should be reading a lower number becuase of the meth.

In summary, if you are reading an afr gauge setup for gasoline and you tune for 11.0 you will still be same percentage away from stoich (safely rich) on both straight gas or a mixture of gas meth.

^^^^^ that is correct, 99% of all widebands read lamba it dont see the difference in fuel

come on guys , we need some more feedback. what gph nozzles are you guys running and for how much horsepower? progressive? displacement? details?

BigRich954RR

iTrader: (1)

you can run as much as u want or can tune for i dont have the numbers in front of me but i think i flow 50-55 gph at 15psi of boost on a 427 on a 93 degree day with iat of 170 i could drop it down to 80 degrees iat yes it progressive 1000hp. all new kits should be

You running pure meth or a mixture, do you have an intercooler?
