Trans-Am Group 7A Race at Laguna Seca

Pardon the shakes. I traveled 3200 miles to see this and I don't carry a tripod on this trek. I've cut out some of the panning, but how often do you get to see these kinds of cars actually racing the way they were intended to be raced?

1997 SCCA Trans-Am Championship @ St Petersburg (Full Race in 720p HD)
Hello there, faithful subscribers. First off, before you ask, why are you UL'ing a race that is already on here, for those who do not know, BMB5150, the famous motorsports channel on here who gave us so many great CART, American Sports Car, and Trans-Am full race videos, was unfortunately deleted by the YT Copyright Hounds just a few days ago for reasons I'm still trying to figure out. Hopefully, he will come back on here soon, but that means that a lot of great races, some of which was only on his channel, are now all gone. If you can offer some perspective on this, please feel free to in the comments below. Now, on to the topic of the video, which is the opening race of the 1997 SCCA Trans-Am Championship. A season that would turn out to be a great, competitive season......that is, if you are a Tommy Kendall and Jack Roush Ford Mustang fan. But, it didn't seem that way going into the season, especially after SCCA Pro Racing changed the Fast Five qualifying procedure and made them pick lots for starting placements, hoping that would curb the dominance of the Ford Mustang the last two seasons. Seriously, tho, how TK didn't win North American Driver of the Year, even with drivers like JG, Zanardi, and Baby Smoke all dominating their respective series that year is beyond my comprehension. Just goes to show you the voters of that particular award and how massive an erection they had towards NASCAR even back then. (as I'm pretty positive JG won the award that year. Or maybe it was Zanardi. Could be wrong.) Oh, well, at least that award was still a legitimate, prestigious award back then and not the total farce it is today, where a NASCAR driver has won that award every single year going back at least a decade. Anyway, I am only posting it on here B/C my main motorsports channel still has that copyright strike from a while back due to that 1970-71 Trans-Am video that expires in June. When that's over, I'll post the rest of the videos over there. For now, enjoy!

Calculate Your Compression Ratio
This is everything you need to do to calculate your compression ratio. No foolin'. Every equation and process demonstrated. Find all your variables. Know your exact compression ratio in every cylinder. This is how you do it. Just because your service manual says your car is 7.8:1 or 8.5:1 compression doesn't mean that it is. Whenever there are casting irregularities, variations in piston height, parts that have been machined, non-OE parts, or changes to your head gasket selection, your compression ratio WILL change. It's highly probable that you're only CLOSE to spec if you've never touched your engine at all since it was "born", and that it doesn't MATCH spec. Even if it did, how would you know? This. 5 variables. V1 Swept Volume V2 Deck Volume V3 Piston-to-deck clearance V4 Piston dish cc's V5 Head combustion chamber cc's The ratio math: V1+V2+V3+V4+V5 = volume of combustion chamber at BDC V2+V3+V4+V5 = volume of combustion chamber at TDC The ratio is... (V1+V2+V3+V4+V5) ÷ (V2+V3+V4+V5) : (V2+V3+V4+V5) ÷ (V2+V3+V4+V5) or BDC ÷ TDC : TDC ÷ TDC First you fill in the variables, then you calculate volumes, then you add the volumes, then you reduce the ratio (fraction). It's that easy. Here are your magic numbers: 0.7854 = Pi quartered to the ten thousandth 16.387 = number of cc's in a cubic inch. If you divide any number in cc's by 16.387 it gives you inches. If you multiply any number in cubic inches by 16.387 it gives you cc's. Quartering pi lets you use the calculation: BORE x BORE x STROKE x .7854 = volume of a cylinder instead of... π x (BORE ÷ 2) x (BORE ÷ 2) x STROKE = volume of a cylinder Either way is right. You get the same result if you calculate pi to the ten thousandth. While I apologize for all the math, no I don't. I'm really not sorry. You actually clicked here for it whether you realize it or not. This is ALL the math, the tests, and the whole process to calculate your cylinder volumes and compression individually even if you don't know any of your variables yet. All of my numbers are present for those who want to calculate out the last 3 cylinders out of curiosity just to see how it affects cylinder volumes and compression ratios from one cylinder to the next. Why would I do that for you? Why would I deprive you of that practice? Just assume that all 4 of my combustion chambers are 41.75 ml if you do this. Clicking like share and subscribe helps a channel grow. It also motivates me. Don't sweat the camera. It's enough to know that so many of you care about what I'm doing here. From the bottom of my atmospheric dump, I thank you all! This gift horse's teeth are all over the place, but he sometimes poops gold nuggets. PS: Use ATF for your piston dish volume tests, not alcohol. Of course it's better just to use the spec sheet included with your pistons... but not everyone gets that luxury. Water is just fine for head combustion chamber tests. Dry and re-oil all parts that water touches.
