Redlined Posted March 9, 2005 Report Posted March 9, 2005 I run LL100 and have for years. See mods. You can run it in your Raptor and anything else you like. You are not getting everything out of the higher octane, in you raptor, but it won Quote
fastbanshee4u Posted March 9, 2005 Report Posted March 9, 2005 [i have run av gas two years,even up to 210 lbs compression with no problem.And yes the fellow at the airport told me would equal 110-115 octane in a car.So you fellows keep paying big bucs for race gas ,while I save loot . Quote
CowboyBanshee Posted March 9, 2005 Report Posted March 9, 2005 Runnin av gas is dangerous and borders on stupid...due to burn...it burns cool, and causes your piston to actually shrink in relation to the cylinder, leading to fragged skirts..seen it a million times on snowmobiles, happened to me a couple of times even...running a race gas is much more safe, less chance of sending a piston to the wild beyond..I am not really sure on why it does it, but it leads to problems Quote
banshee76179 Posted March 9, 2005 Report Posted March 9, 2005 I run 100LL av/gas in my shee...20cc domes/175 LBS @ 600 ft and I have had N.P. with it... just my .02 Quote
ledofthezep Posted March 9, 2005 Report Posted March 9, 2005 I run it in my buggy, stroked VW motor w/a little Marvel's Mystery Oil...I have ran it in my banshee, noticed no power gains, just a gain in running temp. If you can run pump gas, do it. Quote
yfz450ss Posted March 10, 2005 Report Posted March 10, 2005 well dont let the fact that it works ok in a plane make it ok for your quad! planes are able to adjust there air fuel mixture in flight Quote
MotulMonsta Posted March 10, 2005 Report Posted March 10, 2005 AVGAS is the only fuel allowed to be run in aircraft. Type Certificate data sheets provide the range of gas that can be used. Granted the only AVGAS your gonna find is 100LL. Still AVGAS is a HIGHLY regulated fuel. It is expensive to make and petrol companies are loosing money plus the demand isn't all that great at small personal airplanes are the only things that have to run it. The worst thing that's gonna happen with AVGAS in the lead bromides are gonna make you sick and lead deposits are gonna accumulate in your cylinders. That's it. It's all about detonation. High octane prevents detonation. Airplanes can adjust the mix in flight because they have to. Air at sea level is ALOT different then the air at 10,000 feet. Airplanes cannot leagely run race fuel. FAA will take the pilot's licence away. Now there are stc's out there to convert the older planse that run 80 to pump gas. But pumpgas is unreliable. AVGAS is consistant from batch to batch. It's all about safety and reliability in the air. Also, Airplane engines are outdated relics with magneto ignition, it has points, like old 1970's yugo or VW bug. It runs at 2300 rpm. Nothing fancy on em' Your 1999 chevy 350 is a more advanced engine. Quote
Animalman294 Posted March 10, 2005 Author Report Posted March 10, 2005 So from the sounds of things I can probably run 100LL AVgas and be fine, but if I can run pump gas I should. Like I said I only checked into it not to run it all the time, but when I drop to 200' elevation and I get the 20cc domes and advance the timing I don't want detonation. When I am 1000' and higher I can run pump gas, and if I want to be on the safe side I could run 50/50. Quote
05bansh Posted March 11, 2005 Report Posted March 11, 2005 I just stick with my 50/50 mix of race fuel and pump gas. Quote
