New PB

I've been racing my whole life with DOT legal cars and today I ran my PB ever with our '72 Chevelle. I've had this car more than two years and have been cruising around town and attending car shows. Since I didn't build the car I've been making minor changes and getting to know it better. It was the first car I've ever owned that I didn't build but it was built so well and the price was right so I couldn't pass it up.

A quick run down:

'72 Chevelle, all steel, 3420 lbs. Forged 383 pump gas engine, solid roller, Dart heads, single plane, Holley 950, MSD ignition. Engine made 500/500 on an engine dyno.

TH350, 10" ATI 4500, 12-bolt, 4.10, Strange axles, Wilwood brakes, NOS Big Shot, Weld wheels, MT ET Street Pro drag radials, 4" single chamber race Flowmasters, 8-point cage.

We drive the car and have zero issues taking it anywhere. The only track open today was Xtreme Raceway Park in Dallas which is an 1/8 mile facility.

Our best NA pass was 7.61 which felt lazy. If you believe in conversions that's about 11.80. Race weight is 3800. I guess that's respectable but nothing to write home about. Where the car really shined I thought was on nitrous. With the smallest jets for that system (190 hp) it went 6.84 @ 101 with a 1.54 60. Again, for what it's worth that's a 10.60 pass. Also, the air was decent today with about 400' DA. However, it was so cold that I could only get the nitrous bottle pressure to 600 which us far less than optimal. I think with some small tweaks here and there, more seat time, and optimal tuning and air there is a 9-second pass in it with DOT tires through the mufflers and slightly larger nitrous jets.

Overall, we are pleased with the day. Car left the track under it's own power so that's always a good thing!

That's text message and Farcebook lingo. Most of the under 40 ones communicate in acronyms and pidgin English, with minimal punctuation and capital letters. I don't comprehend much of it either.

Re: New PB

Sorry everyone. I'm definitely no where near 40 (that was a LONG time ago) but I frequent racing web sites a lot and assumed everyone knew that PB was personal best. My mistake. Carry on ...

Re: New PB

The term "PB" or "personal best" is used everywhere - at the gym, the race track, sports field, classroom, etc. I don't view it at all as text-speak or facebook-speak.

Thank you. I didn't either but it's funny to me that this post has turned into an indictment against my grammar vs. comments on a pretty good running Chevelle. Oh well ..
