I have looked and looked and have not found anyone yet running a Whipple or Radix making it in the 500rwhp group. When I dynoed 442 with the stock 6.0 I thought 500 plus shouldnt be that hard to achieve. Looks like it may be harder than I thought. I would like to hit 500/500 or more when my truck goes back together.
Anyone do it with a stock displacement engine, 93 octane gas and no help from nitrous?

whitt1 hit over 600rwhp with his stroker and the Radix!

Look at my WCCH thread, there is a truck with a 6.0L Radix with WCCH heads and a very mild cam that hit 471rwhp.

have you seen my sig we are birds of a feather it would seem

Yes, it seems we share the same goal for 2005 I hope we can both make it

Has anyone made those numbers on a stock displacement engine though???
I have seen some make it with the help of some nitrous, but what about charger only?

brian at Magnuson has some data on this I believe. Might ask him

sorry, I mean BlownChevy

i think todd@prodyno did with his little blue truck. i think they sell a power pack that is supposed to be making 500

6.0, heads, cam, 2" headers,80 mm t body, 8lbs Radix = 540 rwhp

holy ****!

I think he sold his truck before he ever hit the numbers. I may be wrong though, hard to keep up with what goes on around here sometimes

Todd WANTED to hit 500, but couldn't do it.

I think I'm close to 500/500+. No dyno though. In this Texas weather, I doubt I'd make it now, but who knows. A couple of months back in cooler crisp air, I'm pretty sure I had a shot at it.

540 rwhp = 11.70 123mph 1.52 60'
