trickdaddygreen305 Posted January 20, 2010 Report Posted January 20, 2010 I have 5 gallons of this laying around and i was wondering wether to put it in my stroker banshee or in my fully bolt on 135i. I was thinking of using it for the banshee this weekend but i see most you guys are using c12 and not many using c16, i was curious as to why ? The compression of the banshee is around 200 per side. Any help would be appreciated, thanks alot guys. Quote
KlotzBanshee Posted January 20, 2010 Report Posted January 20, 2010 This is right off their site www.vpracingfuels.com - C12™ The best all around racing fuel made. Recommended for CRs below 15:1, satisfying the needs of 75% of today's race engines. One of the winningest fuels in racing history, including AMA, NHRA, Modified Tour, GNN, D.I.R.T. and Indy Lights, as well as other local and national championships across the U.S. and around the world. TYPICAL VALUES • Color: Green • Motor Octane: 108 • Specific Gravity: .717 at 60° F C16™ Used in turbocharged engines, blown engines and nitrous applications with CRs up to 17:1. Recommended by the top nitrous oxide companies. Spec Fuel for NHRA Comp Eliminator. TYPICAL VALUES • Color: Blue • Motor Octane 117 • Specific Gravity: .735 at 60° F I think C12 is a better choice for your banshee, but if you have to use the C16 you may want to cut it with some premium grade pump fuel to bring down the octane level some. But 200psi/cyl is alot so you will need some high octane, but not 117. What do you have going on to have 200psi? Quote
trickdaddygreen305 Posted January 20, 2010 Author Report Posted January 20, 2010 basically, its 80 over bore with a vitos 4mill stroker, ported, blaster pistons, cool head, cut domes, 35mm striker carbs. thats out of the top of my head lol. last time i checked compression was around 180 each cylinder.

Race gas is a waste. Cost too much money and doesnt make much more power that premium in these sized motors. Unless your racing and dont want to convert to alky, I would do a new compression check and make sure you need it, if you are lower than 150 use premium. If your too high, I would look into getting new domes cut for your stroker (unless you use a plate) and run it on premium. Just trying to save you money and if your 80 over i'd definitely look into getting some new cylinders... or at least re sleeved. Quote
wacko2000 Posted January 21, 2010 Report Posted January 21, 2010 what pipes are you running? What size jets are you running in your airstrikers? I have the same carbs and they where a pain to jet Curious on what sizes you ended up with Joey Quote
