Long story short, thinner rings were worth about 7 HP on an moderately tuned SBC V8. So realistically, on Rei's V6 they might be worth 3-4 HP. That definitely doesn't justify buying a whole new set of pistons and rings. But it's something to consider if you're in the planning stage of a new build.

I will definitely take that in consideration for my 8000RPM Supernatural!

Are you guys familiar with a product called MotorKote? I watched a YouTube video where a guy tested it, and got some really impressive results. I'm thinking of putting that stuff in my Fiero, to keep the cam and lifters happy.

Side note: on his YouTube channel, he tests a lot of other engine additives, as well.

That was my co-driver's first road course race and you can see that he backs off several times just before the main straight, making it much harder for the Fiero to out power the other car. He also overrevs the car on his downshifts; memory tach read 6600 rpm, fuel cut was 6300 rpm and shift light was 5500 rpm. After seeing the video and a short conference he worked hard on getting that under control.

And this is the middle of a run at the Ridge. That was where the MAF was causing extreme lean conditions, engine backfired hard and broke one engine mount and also the exhaust. This is after chaining the engine down and welding up the exhaust. I called it after pulling a spark plug and seeing some pepper on the insulator.

Same driver, still downshifts too early and drags the engine rpm up past the 5500 mark but not as bad. The worst was a rental driver that missed a downshift and spun off into the gravel at Laguna. Memory tach read 7600 rpm after that one. We had the fastest lap of the weekend but couldn't seem to stay on track for more than a couple hours at a time from self-inflicted issues.

I have more video but haven't put it up. I think there's another of my other driver but he was pretty slow.




So, you rent to individual drivers?

Indeed, very impressive!

Only to local drivers that I know quite well. As you can expect, I have a lot of time and money tied up in the car and I have a hard time letting someone else drive it.

I completely understand! There are 3 things I don't let anyone borrow and this is the order: My car, my tools and my wife!



Going back to the driving, this passed weekend I became officially a performance driving instructor. I spent the entire Saturday from 7am to 5pm from classroom to the track. It was in Summit Point, West Virginia and the track we use was the Shenandoah Circuit. I been to the Main racetrack many times but this was my first time in this one. That is an awesome and busy track, it is like a mini Nurburgring. It even has a "Carousel"! It has an uphill straight leading to it and right before the carousel there is a BIG dip! Every time I went through there with my Abarth it went airborne. It hit the rev limiter and at the same time I realized I'm off the seat and then back on it! It was awesome! It was a 10 hour drive back and forward but it was worth it!
Can't wait to get the Fiero ready to take it there!

Thanks for understanding, and congratulations!

I did the Ross Bentley instructor's clinic a couple of years ago at our local track. I was paired with an established instructor who had several years of BMW schools and such. He brought his Black Series C63 and I had my son's '99 C280 Sport. We only did a few laps in my son's car then spent the rest of the day in his car.

I think he was pleased that he was my "instructor" because by the end of the day I helped him drop 5 seconds off his lap times!

Thank you! Same thing here. My instructor was this old seasoned veteran guy in a 2009 Corvette, that old man can fool you! He drove like a computer, and he was fast! When it was my time to drive and him on the passenger seat, going from a Vette to a tiny Abarth was scary for him. The only thing I told him I was a Kart racer and he was like "Damn, is this how it feels like to drive a big Kart?" He didn't last 2 laps! He hated going airborne!
He did tell me that I did a fantastic job on the driving but the clinic was about the student and my safety, a lot of psychology involved.

Very cool!
