safest whp for race gas?
i know you can get some pretty high numbers with race gas, but what do you think a high number would be safely that would last a little while? only talking about running race gas at the track maybe once a month. thanks

people push race gas to 800+hp so you can safely run 800hp on race gas.

sorry i guess the post was pretty vague, not a noob just dont post much. the motor is a stock b16, do you think 400 whp is good with c16 at the track

NO, race gas is going to reduce the chance of detonation but will not stop your pistons from melting. Race gas gives you a hotter more efficient burn. That on top of your stock cast pistons and 400hp leads to a blown motor. You should not go higher then 300HP on a stock motor and even then it's not going to last you very long.

we dont need more tards on h-t im doin us a favor, race gas has a higher octane rating, burns slower, more resistent to pre ignition/detonation, some race gas has specific gravity and others can be very oxygenated. The purpose of race gas was not a hotter burning fuel with a more efficient burn lol.

First off I never said it was the "purpose" of the fuel but it certainly DOES burn hotter AND more efficiently. Anytime you raise the octane rating of fuel it is going to burn more efficiently. Not one thing I said was inaccurate so GFU.
Oh and please tell me how the gas itself is more resistant to detonation. It's the way it oxidizes and burns not the gas itself.

straight from sunoco race fuels
Most people think the higher the octane rating the hotter the fuel burns. It's actually the opposite, the higher the octane rating the slower the fuel burns. Thus enabling the tuner to lean the fuel mixture down because they are now dealing with a more controlled burn rate. Thus making more power. Also, each motor requires a different ratio depending on modifications. So you don't always have run straight race fuel.

Re: (quicksilver1689)
Yes it takes longer to burn and requires less fuel. But when COMPARING it to a lower octane rating fuel, the same amt of the lower octane will produce a lower temp compared to the same amt of higher octane.
Simple test, take a cap full of gas and set it on fire. Fell the amt of heat that comes off of it. Now take a cap of Jet A (jet fuel) and light it on fire. Let me know which makes you feel all warm and fuzzy inside. lol

Re: (White Smoke)
jet fuel... that is the mad tyte jaydeem racer fuel huh.... jet fuel make u supa dupa fas... 
also when you say race gas burns "more efficiently" or burns "hotter", I asume you are trying to reference the energy volume of said fuel?
EDIT: correction, typing fast at work and owned by misuse of word.

avgas is basically 100 octane leaded fuel - ive used it with a mix of 91 in my car before with good results. However, these days, avgas is really no cheaper then 110 octane race fuel and therefore no point to use it. If you do though, make sure if you use 100LL avgas ie the low leaded version, which still has a ton of lead, but less then the other stuff.
All you ever wanted to know about avgas and more: http://en.wikipedia.org/wiki/Avgas
Ah the days of $2 a gallon avgas...

There is a local kid (chime in) making 407whp on a stock B16 and has been running pretty good for a couple months 11.0 on slicks 11.8 on street tires PWS trim
i think this was on 50% race gas 112 and 50% pump

Re: (liam821)
I am a bit familar with it, thank you.
For reference I was refering to actual aviation fuel and should not have used the term avgas. White smoke refered to Jet A for his proposed test which is kerosene/ paraffin oil-based based jet fuel and what I was basing my comment on... good for turbines or maybe deisels but not gasoline piston engines.
I will correct my post, fast typing at work owned me... I stand corrected.
Though I will add that actual avgas is not the best source for a race fuel/ octane increase either imo, and I would say it is more like leaded gas from 1960 than anything. The octane is not rated by the same system that rates automobile fuel (although it is somewhat similar)... so 100LL is not quite the 100 octane you might believe it is. You were basically just adding a **** ton of lead with very little octane increase by a automobile standard of rating fuels. Also avgas has high levels of aromatics which result in poor throttle responce generally in piston engines, which is not a major concern for a plane but is an automobile. It was formulated for high altitude so low altitude use results in a lean condition without some added fueling compensation. Avgas has different lubricating properties and additives that I could go on about boring you but I will just cut to the chase and say its better to seek octane elsewhere imo.
If you want just add some tetra-ethyl lead to your fuel and you can achieve higher octane ratings with the same 1950-60's approach that is used for avgas... but fair warning it is highly toxic.
I know someone will say well I used it and it worked... well congrats, that does not make it good.
Sorry seems I am straying off topic... back to it.

Thank you for saving me the trouble of typing it. I work in aviation for a living and get so tired of hearing people refer to "jet fuel" like it's something special. More like dirty diesel.
