Sorry, I wasnt trying to be mean. It just makes me wonder about our cars with teh same computers. I dont know wheather to believe Harry or not since he has already blew up 2 motors now??
Since it dont look like we will get our cars back before thr tracks close (we are getting rollcages put in for like 6 months now!!), I just want to know who is right so we wont blow our cars up too.
But we are FOR SURE using racegas anyway! No offence but since premium gas is like $3.40/gallon, it seems pretty dumb to not spend $1 more and be safer. Even if it was $3 a gal more it would still be smart with an expensive motr wouldnt it?
We have been reading about your car for a long time cause thats how fast we want. But why have you changed motors and heads and computers so many times? Shouldnt you pick something and stick with it until it right instaead of always trying other stuff without ever fixing the old stuff first? I am just thinking out loud.
Thanks for all your tests though, I'm sure it will save lots of peopel in the longrun.

steve, if you got video you want to post, then post it.... but make sure you put the good run on this video too so it wont be all bad.

even though that might be......... this is the area i hang out in........ of the 4600 posts i have i bet 4000+ are in here so alot of these guys i know very well...... Esp. Dave.......
Sorry again dave. Ill let people keep running there mouths about trying to run pump 93 and in the end they will see..... its just to much $$ to play with anymore.

chris the motor started with significant blow by on the third pass of the ls1 tech race, the pass after i went 147.97mph on pump gas
the bs3 you can set up to correct for a lean condidtion, but if the fuel system would be maxed out then it could not add anymore fuel no matter what. i dont think this happened.. i think it just detonated from not enough octane (or the meth not getting divided equally in the cylinders)
motor is getting fixed now at wheel to wheel

We had Harry at Precision Turbo put the Big Stuff system on our cars and he said that we can't go lean. Don't know if thst's true or not, but that's what he said anyway.
He also said dont trust pumpgas with a expensive motor. He said race gas is cheap insurance. If we had your money, we could throw our money away.
What are you going to do now? Build it up more ro fix it?

Not sure What Harry at Precision Turbo you are talking about?
Maybe my clone has been out making trouble.
Let me know what he looks like , will ya?
If he (clone) was putting this stuff on your cars, maybe ya have pix ?

Don't let this disuade people from running meth, it keep your motor safe. There is a limit of course. I personally run meth and have been able to achieve 15psi on a stock motor with just 91 octane gas in 100+ weather. It's just single gear pulls and I did it just to see how well meth worked while closely monitoring the engine. It's good stuff, but be smart with it. I normally only run 10 psi on 91 and then spray a little meth on top of that for extra safety.
When I beat on the motor I usually put 100 or higher into the car.

Ya i aitn saying ya dont knw0o what ya are doin MM bt somethign went wrong. Forged units dont get that f'd with out alot of help. I know 900 hp is alot but those look liek the had alot of detination. I dunno. I just wanna see ya stick with teh meth. Its cool to think that that is exactly the same way ya drive to and from teh track. GL man

Wonder if distribution on the meth was "the" or "a" problem. One reason i think a single plane intake would help when shooting alot of meth. The ls1-6 isnt meant to flow liquids, the single plane is.
Even with that said...... i believe now David will use a higher grade fuel at the track from now on..... its just to much to risk and he showed us all how much it can really cost you by not spending the extra $40-50 on a couple gallons of race gas compared to $5k+ worth of damage.

I just smoked 3 motors in 1 month trying to run Methanol at ~20 psi and 93 octane on a 383 LT1. The first 2 were just broken ring lands on one piston each time. I was able to swap pistons without pulling the motor. I thought the Methanol wasn't coming on consistently, which I thought I traced back to a bad connection and thought I fixed the problem.
After the 2nd broke piston, I got it together and it ran great. I set the A/F ratio to 11.5/1 and went to the dyno. The car had already made 680 rwhp before the previous round of mod's, so I was expecting ~740 rwhp this time. It made a whopping 590 rwhp and melted a hole in a piston - while running 14/1 A/F ratio. ON THE DYNO PULL, I WATCHED THE METH ACTIVATION LIGHT COME ON, AND WATCHED THE KNOCK RETARD, WHICH NEVER WENT OVER 4*. Now, I hear of people having trouble with the Shur-Flo pumps degrading due to damaged diaphragms. Just wonderful . . .
So, Methanol, which is supposed to keep the engine safe, is responsible for 3 blown motors for me.
Mighty Mouse, did you ever figure out for sure what caused your incident?

I personally don't think that Meth alone will support 700rwhp or more safely all the time.... And if someone wants to counter me fine, but show me what mph you run at the track.

im thinking that you just cant spray a lot of it evenly, or consistently or something..
i know a little helps a lot, but i dont think a lot helps a lot more.. follow me?
im only running race gas over 17psi for now.. period.

i think you can ran as much hp as you want if you run enough meth BUT at some point distrabution becomes a problem. isn't there an article about twin turbo motor with no intercooler using only meth as a fuel dynoing at 2200fwhp?
for a race car i agree runing race gas is the only way to go but for those of us that like to drive it on the street all the time swaping out the fuel and running a lower boost is a kind of a pain. i can run to 11psi max on pump gas, 16psi max with my standard meth kit turned up most of the way and have been over 20psi with the meth and 114octane.
my question is if you did set up a duel fuel set up(staged injection) with 16 injectors would you be better off running meth in your 2nd stage or c16. i was thinking a nice twin turbo set up with no intercooler and 8+160lb injectors spraying meth for my staged injection would be bad *** and some little 42's or whatever running pump. turn off the pump injectors as the meth injectors turn on.
