I have put the race gas in from day 1. as you see hear the timing at 33 is about as far as you can go putting in the race gas does not mean you can bump up the timing. Most of the time my timing is at 32 I have it at 34 rt now and don't hear anything. I lock it up in 3rd gear and step on it some and listen for it so far good . this last time when I went out I bout 5 gal of 93 and put a gallon of race gas in seems ok with that. I have some lead substitute I bought of Amazon couple years ago may try some of that, got a case of it.
So are these the gaskets to use? Rock Auto has them. $9.97 a set. I bought a set of the Hookers when they were being liquidated, surprised the middle bolt hole was already notched.
I’ve used em before with iron manifolds, they work fine, this is the first time I’ve used em with headers, so far so good. I don’t see any reason why they wouldn’t hold up except if a bolt gets loose and allows the flame to burn thru, but that happens with the best headers gaskets.
Here's some handy info. Please note that using any higher of a Octane level then the motor needs to not detonate will on,y serve to cut into power levels and slow down the rise of rpm.
We use 110 Leaded race gas those numbers will be a little higher. All I can say I have used the race gas for over 25+ years with 10.6 comp 5 gal with 15 gal of gas and all has been good. Yeah you put 110 race gas in a 9.6 motor and it will go slower. When I first went out after cam change the valves would rattle if I pushed on the gas too hard, I went back home put in the race gas and that quit making noise. But that timing was too high also I had to back that off 38* back down to 33*
Race gas does not make you put more timing in it just slows down the explosion from going early. Timing usually stays the same.
When things are right It’s not a explosion, it’s a burn! At the fastest rate seen in a race motor were talking about some 120 mph. A Dynamite explosion for example is about 2000 mph.
It was the only word I could come up with in a hurry had to hit the road, jeeze. Throw a match on gasoline it doesn't burn it goes boom! explodes! really guys.
This is interesting, burn, boom, explodes, goes out. So what is pushing that piston down I'm confused.
Lolol, if you pour gasoline on the ground and light it it ignites, “technically” it doesn’t explode, BUT under compression like in an engine, it goes boom bam thank you ma’am, I’ve always heard the combustion process referred to as “controlled ignition” or something similar. Either way, I need more push on my pistons to get into the 12s
It's all just semantics. What is ignited is gasoline vapor, and upon ignition via spark plug we hope it burns rather than detonates (explodes) on its own, thus detonation. The vapor is able to be ignited and burn because the gasoline molecules are getting friendly with O2 molecules in air. Yes, one can extinguish a lit match in liquid gasoline. While doing so be careful not to ignite the gasoline vapor at the surface of the liquid as Mark mentioned. Devon
Once knew a guy who regularly put out his cigarettes in a ash tray with gas in it... 'course he was a little nuts. Jim
