Run the right elemnts and maintain them so you wont have to monitor it. Plus when you going that quick who the hell can look at the gauges anyway. Real fast cars don't have gauges they have dataloggers/dashes with very bright warning lights or ecu's setup to do the same.
When I saw your broken apex seasl the first thing came to mind was that it was not detonation but was excessive seal growth from either too lean or tight clearances like they would be in a stock motor. You can tell that often from the color!

That's crazy though, for someone to go through all the trouble and effort, and money and time for a small peice of paper to gernade the motor in sec's what took him/her hours upon hours time, sweat and blood to build is just crazy stupid.

Man allen keep you head up man you going to get that **** up in running again in due time my friend

I didn't know what i was looking at but you are correct, all the little pieces that came out were blue like they had got very hot. I didn't know that was abnormal. On one of the side housings on the plug side there is a little gouge that looks like it was made by a very sharp pointed object contacting the iron.

I have been doing a great deal of research and one of the things i have been looking at is seal clearances. I have found a lot of info from Judge Ito on other forums. Care to reveal any secrets as a new year gesture?

Allen is a quick learner and smart enough to listen to those who have been there and not to question experience. He's going to be even much quicker next time out.
Nobody knows it all. It's a learning curve for everyone. Some have just been there allready.

You learn that in a hurry with big nitrous shots. Ever seen the apex seals turned into little molten *****? I have!

It took falling down a couple time to figure that out.

Correct me if im wrong but if you have ethonol content high enough and premix with like caster oil it will coaugulate! I know it does with methanol! Like you said cris experience.

You gotta balance the positives with the negatives.
Castor is the most forgiving lubricant that exist. The greter the friction and the more heat the better it works. Totally opposite to other lubricants. It's just keep on giving.

Very interesting articles now i have more questiones than before i read them. But for race engines caster oil will alow for the best power and protection but with some side efects. Synthetic will give ok protection and burn cleaner over the long haul. Do i pass cris or do i get the pointed hat?

That slime isn't the chemical liner that you used to seal your aluminum fuel cell breaking down is it? Maybe it's not compatible with C 16 and castor?

I've never heard of using compressed air to backflush a fuel filter. In fact, a soaked paper element should act like a brick wall if you try to force air thru it, considering the tiny pore sizes (surface tension), and high flow rate of the compressed air. I would expect this to rupture the filter and destroy it.

Have you done this before with different results? Were you monitoring your fuel pressures?

The easiest way to check for a restricted filter is to blow trough it (with your mouth). I was just trying to dry the filter out so what little fuel was left wouldn't turn to varnish while i built the motor. Even a fuel soaked filter in good condition should flow as freely as a dry filter. I monitored fuel pressure on the dyno but not after that.


Thats the first thing i thought Chad. I stuck my hand in the cell and the coating was still hard as a rock.

What coating are we talking about here and what type of fuel cell also?

It is an epoxy (2 part) coating that said it was safe for all types of fuel (including methanol). I bought it because i had a small leak and also was worried about running methanol inside a bare aluminum fuel cell. I think the brand was caswell or something. It dries clear and is hard as ****!!!

I heard from a birdy that for turbo/no2 applications- apex seal to rotor housing clearance- .0015-.002", apex seal to rotor groove-.002", sideseal to rotor groove-.002", sideseal to corner seal-.003"

ps. I would listen to REne about not using the paper filters.
