HKE pump gas 445ci with TFS 235s lays down 574/482 We got our new HKE 445 assembled and LMR installed it this past Friday. Joe at LMR did our base tune to get it idling strong and to keep us safe until it could be tuned at the track. The tune was safe with a max of 27* timing.
We weren't really shooting for huge dyno numbers or we would have pulled the mufflers, ran a solid street tire instead of 30" drag slicks and really got aggressive with the tune.
The car put down a best of 574/482 with pump gas running through a powerglide and 4800 8" stall converter. That's with slicks and mufflers. We were pleasantly suprised to say the least. In the same trim we headed straight out to the track and ran 9.50s @ over 141 mph with a soft launch. The first 1/8 mile pass was a 6.00@114mph with a 1.31 60ft.
The car weighs 3150#s and it's a HKE 445 hyd roller on pump gas.
I just thought we'd share the info with the dyno guys. It'll run some low 9's once we get her to go straight and get the tune dialed in and figure it would dyno a little over 600rwhp once we drop the exhaust and get everything tweaked just right.

HKE pump gas 445ci with TFS 235s lays down 574/482 So you can make higher dyno numbers with a street tire verses a slick? With the street tire won't you loose traction and spin the tires on the dyno?

Yeah the flat graph is characteristic of a loose non-lock up converter on a dyno. It would have shown higher numbers with a high peak with a real tight or lock up TC.
We are still running the Fast 90/90 intake/TB. The cam is a 258/262 custom comp grind. It's not a big secret really. Erik and Greg selected it specifically for this combo.
We are using an L92 aluminum block.
A stiff tire like a drag radial will generally produce higher numbers on a dyno. That wasn't our intent for this dyno session. We just wanted a good safe tune and we got it.
