278 dyno'd HP with a 230HP TST kit?

[Dennis Garrett]

I have a 97 2500 w/auto, and it just hit 132,000 miles. Right after I bought it new, I installed the TST 230HP kit. Today there was a small TDR get-to-gether at a hotrod shop in KC. I had my first chance to put it on the dyno, & was surprised at the numbers it spit out. They tested it twice, and at 2300 rpm, it showed 278. 8 HP, and 646. 1 max. torque, AT THE WHEELS! This was done in locked-up "D". IF you figure about 10% mechanical loss from the flywheel to the tires, this thing could be hitting over 300HP! I have a K&N filter, a hollow cat, and have slid the plate forward about 1/16", but no other performance mods. Also using straight #2 fuel with no additives. After my test, they hooked up a new Ford F-350 with the Powerstroke & auto. It hit 275 hp, but only about 450 torque. It was 95. 6 deg. in the shop, it might have done better if it had been cooler. Seems like a lot from a 230 HP plate, you should have seen the smoke.

Those are some good numbers.

You think you were suprised at your numbers? You should have been there when I dynoed mine in January.

283 RWP with the stock plate slid forward, K&N RE-0880 air filter, and a 3 inch straight exhaust. We didn't have a way to get RPM's so I couldn't get a true torque number that day.

Ya can't beat these ol 12 valvers in the free HP department.



BTW, mine also had about 130,000 on the ticker when I did it.

Dan got 351hp. I'm too tired to say anything else right now.
