XCR1250 Posted April 3, 2018 Share Posted April 3, 2018 Race Fuel doesn't make more HP. Quote Link to comment Share on other sites More sharing options...

If you have a massivly high compression engine you need to match the fuel and octane rating to it. Using a lower (non race fuel) can cause problems and result in lower HP output. For engine efficiency and power, higher compression is desirable. Neal Quote Link to comment Share on other sites More sharing options...

Pete Posted April 3, 2018 Share Posted April 3, 2018 My bro in law runs 3 circle track cars. all 10:1 motors. Could easily run pump 93 but they are forced to by Sunoco race fuel. huge waste of money Quote Link to comment Share on other sites More sharing options...

Indeed, but you can't get the same HP out of a engine designed for 110 octane using 87. It will produce less. The high compression engine will be more efficient.

MiSledder Posted April 3, 2018 Share Posted April 3, 2018 The oxygenated fuel we ran in my son' 2 stroke dirt bike sure seemed to make a seat of the pants difference, it was crisper, rev'ed quicker, hole shots got better Quote Link to comment Share on other sites More sharing options...
XCR1250 Posted April 3, 2018 Share Posted April 3, 2018 When cars were forced to pass emissions compression ratios were dropped and mileage went way down, so it's true they produced less pollution but used more fuel so where was the benefit? My 1968 Pontiac Executive 400 cu.in. got 23 MPG and was a huge boat. 3 minutes ago, NaturallyAspirated said: Indeed, but you can't get the same HP out of a engine designed for 110 octane using 87.

Neal Again that's obvious, my point was some folks think using race gas or premium in their street cars or trucks will make it faster/quicker and that is simply not a fact.

NaturallyAspirated Posted April 3, 2018 Share Posted April 3, 2018 5 minutes ago, ATOMIC PUNK said: octane is for detonation period.. it doesn't make more power.. Incorrect, it can/will make more HP in a engine designed with higher compression. The energy content in the fuel is the same, but the efficiency in extraction of that energy matters. Higher compression engines (as a general rule) are more efficient. Neal Quote Link to comment Share on other sites More sharing options...

XCR1250 Posted April 3, 2018 Share Posted April 3, 2018 (edited) After compression ratios went down I had bought a 1978 Riviera with a 403 cu.in. engine, it got 11-12MPG, 1/2 of what the much higher C.R.Pontiac got.

Neal Are we talking fuel or engines? Because I thought we were talking fuel. But if you want to talk engines, then just turbo the fucking thing.
