Don Terrill’s Speed-Talk

This is in car video from customer Larry Larson's quickest pass to date, a 5.95 @ 245mph in Las Vegas at the Street Car Super Nationals.

Larry's truck is based on a Chevy S10 pickup, built specifically to the rules of the Drag Week event, so it's licensed/plated/insured and covered 1400 miles on the street (pulling a 2800lb trailer, logging 9.5mpg) with ease.

Engine is a Proline-built 620cid Chevy with a pair of 98mm Pro Mod 2 turbos from Precision. I can link an article to the build if anyone wants to see it. Meanwhile, here is a pass with some data.

Interesting to see how slowly the boost builds, doesn't hit 50psi until nearly 4 seconds into the run.

Sure...link the build article.

Wonder if thats intentional

It is intentional for sure, bringing the power on gradually to avoid overpowering the tyres, as well as just using enough power to win the race.
