I've had the VibraTechniques in my race car for 6 years and no problems.

Dang Vaughan, you're not making this easy for me to ignore....procrastinator that I am.

New cams always wake up other gremlins!

With me it was fuel pump wiring. I believe that in H-Prod we can go full Mega-Squirt and solve both fuel and spark issues. And make it easier and quicker t ...

For external diagnostics before tearing into an engine, the leak down tester is THE tool. Put a piston to top dead center, inject 100 lbs of air and read gauge. Anything less than the mid to high 90 ...

Bent valves will give you that type of lack of compression. Hard to believe that all four cylinders didn't seal unless you only had the head bolts finger tight.

Last winter I pulled my IT-B engine after 5 years or racing. I stuck in the H-Prod cam to run it last season in the new class but no other changes to the IT-B engine. It ran fine to the end. I'll g ...

I just looked through all my stuff from Dema and can't find a recommended valve lash. I seem to recall back when Hayes did the first grinds that he said to use stock lash. That's what I've been doin ...

Since you have gauges, buy a couple cans of refrigerant that has UV dye in it. Put it in the system and run it quickly. The UV dye will leak out wherever there is a problem. Also buy a little black ...

Mike, Wow, another weird one. In 46 years of racing I've had some strange things happen but never had the dipstick pipe (and dipstick) disappear, usually a corner worker will retrieve the errant par ...

Thanks for the ideas...since I MacGuivered the car at the track and that part held, I might just go with a larger catch tank. I'll leave the AccuSump closed, drain the oil from the engine and put bac ...

Compression is 11:1 on the new engine. I'm thinking vibration more than blowby to kick out the tube in the block. Otherwise the dipstick would have just risen up or been pooted out.

I ran the race weekend at Summit Point this past weekend and discovered an interesting failure after qualifying and racing on Saturday. At impound, they asked that all engine lids be opened so that t ...

Vaughan,
The only fitting I was able to buy was at the top of the fuel distributor. Every other conversion fitting I made was cut and splice via silver solder. It has worked for a year now but.... ...
