I've got too get up there tomorrow and take my carb off and re jet and change fliuds n such!
Pretty good stuff in this thread. What will "NEVER WORK" for some is because people don't want to think and research for themselves, just go by what others have said. I'm on the verge of deciding what fuel to run for '08, and IF I could make 1000-1100FWHP on a single set of 160s I might just try that to start with, so I dont have to worry about driving another set of injectors. I had to get rid of some weight this winter, and the intercooler and stuff was the only logically way to get it at this point!
The only thing that "bothers" me about going to methanol is that I only have 9.5:1 motor.

I run NGK but the Autolite has a cross over number for it and is about .50 cents more..
So NGK it is... Now all this I posted is for a Forced Induction....Running a warmer plug on an reg alky set up will still work fine... LS1 Tech Stories

Too all my Brothers on here that I haven't met in person but will talk too you the same on here as in real life...You can run Alky on the Street and love it...
We ran a SBF down here with a Ron Toilet Injection and was vary street Friendly in a 13:1 motor and had a plate uder that but never needed it!
Befor you say about it burning 2x as much...Almost yes but not quite and averaged a little less than 116....Going too town and back was great...Long drives,no or had too have a follow vehicle with extra fuel carried...
This car ran great with it!
heres a pic of the Rons ....

No they don't but do great on the street and works good with a plate!
Now thwe one on my car is a Blow Thru Carb on alky from C&S and will work but cost about 7-800 more.....
Since you said something about spark, should I run a hotter plug than I've been running? What about the gap?
Frank,
With a 9.5 static compression ratio you most likely won't have to reduce the plug gap at all. On Methanol you could most likely run as much boost as your turbo is capable of. The key to Methanol is it will reduce your intake temps approx 3 time lower than gasoline is capable of.
The biggest issue I had was supplying enough fuel to feed the horse power levels I'm shooting for in the future. With as rich as a 4.5:1 afr, mechanical fuel pumps are almost an absolute. Conventional regulators also have a hard time returning enough fuel at low rpm with EFI. In my case I run a 7 gpm Waterman mechanical pump with an additional poppet valve set 10 psig higher than my regulator to control fuel delivery. Traditional blown alcohol guys don't typically run regulators and use restrictors and bypasses to control fuel delivery.

ya he bought an aeromotive belt drive, I cant remember the reg. part number but its a tall skinny one. Thanks for your help on things, we only have 1 efi (methanol) guy here local to talk to. and he stays busy.
14.5:1 Compression single 106MM on alcohol. Views, thoughts, Ideas?
Before anyone says it can not be done I have a friend running 13.5:1 compression and running twin 76's with carb blow through alcohol setup. Power comes on so crazy its unreal.
My thoughts on this is instant spool.
Cheaper cost. No Intercooler needed, No water Pump needed, No Radaitor needed. Cheaper fuel cost: Alcohol is 4-4.50 gal vs 7.00 gal race fuel.
Ci would be stock bore but with a filled block. IE All water passages filled with block cement.

We are trying to locate who was vid taping during the 3 pulls. I was busy watching the bowls and made sure they were staying full. Another one of our friends was watching the AF meter and Billy was doing the pedel and watching the boost gauge. TEAM WORK
