That is wha'ts interesting. When it was listed last time I asked about a dyno sheet and again, no go. Takes a 1/2 hour to get dynoed. Hmmmmm.

3300 lbs and does the 1/4 mile in 13.6 @108 with 5.2 sec 0-60. Do that math and see what you get. I'd put my faith in real world road test data before a dyno sheet. Do you lose the race and then pull out a dyno sheet from the glovebox and say "see I win, I have more peak HP?" Dyno sheets don't tell the whole story...for example take a centrifugal car and a turbo car making the same peak HP...4th gear cruise at 60 MPH....no downshift, drop throttle...turbo's compressor comes on full tilt NOW, centrifugal is waiting for the redline to make the boost. Go further, allow the CS car to shift down to 3rd and hammer it. By the time you get in into gear and start making the boost, the turbo car is already out on the horizon. It is totally possible the two cars in this example could be making the same peak HP. I've explained this at least 20 times on here. We have also already seen how much faster my 4.5 liter 3-spd auto on 10 psig is compared to a 5-speed CS intercooled car running 9 psig. It was like .3 sec on the 1/4 mile...give me a 5-speed and I'll widen that to 0.6-0.8 seconds difference. Here in KY we call that a whoopin' (recall I just live here, I'm NOT a native
Need I remind you of the analytical lesson someone got when I posted the Callaway's numbers? He was wrong, totally wrong. You are skeptical of the power...come to KY and get a ride. I'll even give you the spare bedroom for the night. This individual was skeptical until my Callaway made the total power level I said it would then he became very silent...so don't trust me if you wish. Would you settle for a MAF voltage reading through the laptop? "The Individual" didn't believe that was accurate enough either...but it was.
Yes it only takes a 1/2 hour...more like 1/2 a day by the time you are through...a half a day that I don't have right now to mess with. There are only a handful of people even on this board who really totally understand the relationship between torque-speed and HP anyway. So, are you all just stirring the pot or would you like to place a healthy bid? I'll throw in the Goldmember action figure and official Goldmember DVD with behind the scenes footage if the price is right!
What is wrong with two K-26 units? The Callaway will make over 400 WHP and a boatload of matching torque with those small units running just 12 or so psig. I don't need an oversized turbo to make the amount I want to make. You don't use a sledgehammer when you need to drive a finishing nail, right? It is about proper matching and I see the K-26 as a nearly perfect match for the 4.5 liter 928 with 5-speed.
BTW...Might end the auction early...have a guy in VA interested and I've given him a reasonable number! Who knows, I just might surprise you guys...

Think of the Dyno sheet as an independent 3rd party to verify your claims. I believe you, others believe you, but the majority of people on Ebay are not here, and just because you claim it has 400+ hp desn't make it so (but I believe you). There are a lot of false claims made on Ebay, so unless you have something to back it up, it's just noise. Think of a dyno sheet as another tool in your quiver of marketing arrows. If it doesn't sell this time... Get it Dyno'ed. Good luck.
