methanol and flywheel help

[pheonix]

im going to run methanol in my 99 v6 automatic firebird and know i have to use almost twice the fuel running meth. i know all what i need to do and parts but im having trouble finding what size fuel injectors i need. also im looking for a aluminum flywheel to go along with my 3.73 and carbon fiber driveshaft to help lighten things up can anyone help me out.

Depending on how much horsepower you are looking to get out of it, it varies.
85lb/hr injectors are good for as much as 500HP NA, with methanol, with 60PSI fuel pressure. 75% duty cycle.
68 lb/hr for the same setup, making 400HP NA
51 lbs/hr for 300 HP NA.

sure about the ligth weight flywheel? it might not be what you think

[pheonix]

the 51 lbs/hr should be it its all stock except for headers exhaust drive shaft rear end and ignition. if i super charge or run nos i can up grade. so im looking at around 300 hp probably with meth and tuned. so you think this will work. and whats the best place to get these size injectors i kind of want to go venom pump and injectors.

Spec makes an alum flywheel. Its a bit pricey though.

thanks for the info on the flywheels.

what kind of racing are you looking for? drag or a road/autocrossing?

road racing and drifting

Methanol is hard on engine enternals, use care.

M85 should be availible at the pump, easier on engine internals, not require as large an injector size, easier to start on a cold mornings and still 102 octane.

Do you mean E85?

alright go for a lightweight one, but they are a little pricey, I think like $400

M85 (85% methanol) is out there. I don't know if pheonix can find it but it is supposedly available in Texas. E85 has the same benifits (even more so) over straight methanol as M85 (and more miles per tank). I do worry about the 15% being really bad gas but if the pump has an octane rating over 100 it likely is true.

If you car is an automatic then you will have a flexplate and not a flywheel. If you do have a M5 then you can get the aluminum flywheel through Tom at Supersix Motorsports. I installed the first one in my car and it works great, 11lbs which is 1/2 the weight of the stocker.

i was going to swap the transmission out but money will be a little tight after the methanol so i just decided to stay with the auto so know i need to find a good place to get a flexplate. i have emailed a few places but havent heard anything yet.
