I'm happy with high 80s

I think 950 hp spinning a Konrad should get you over 100

Well there are a good number of Y2Ks running around with big power but none running 100 consitantly.
My guess is that if you hooked 900HP to your XR you'd see 100 with the right conditions.
If you want to run 100 consitantly then you probably need a little bit more.
There are guys out there running 1000HP with Bravos but I don't think they last more than 20-30hours.
I think Huntington Beach is planning 1000HP hooked to a Konrad. That is going to do it for sure...

With bigger hp comes more maintenance and loss of reliability.

Come On P.e. You Can Adjust Some Valves Once And A While. Readjust Some Fuel Presure Now And Then.

Well, we touched on this subject a few times while Gary was having his engine rebuilt.
Whipple pulls 750+HP out of a 3.3L charger at 7lbs on the 525EFI.

The smartcraft may have to go though...

Just make sure you have your best driving skills hat on if you plan on running a 5000 pound V over 100 often. Especially if you like to drike rum & cokes once in awhile!!!

750,s not enough. We need to take giant steps. What if Gary where to take a blower like the one from the merc 850 twin screw type, intercool that with the cooler from the 700 only 3/4 inch higher and keep the computer and his flat hatch !!

Whipple has a 5L that would probably do it but I think a basically stock GM 502 block will come apart over 750HP...

To make 100mph consistently on the older style bottom you need 950hp w/ bravo. 1000mph with konrad.

Thats my goal to hit 100mph middle of summer lake havasu heat. Theoretically 1000hp gives you a top speed of 114.8mph using Tom's numbers when he hit 94. Subtract the unknowns and 1000hp should get you 105 consistent.

Gary, I would think 900hp would get you there whenever you want as long as that bravo holds up. Do a MM drive or a B1 and build 900hp, be nice to the drive and you'll be flying in the triple digits.

Rob, thats what I was thinking HP wise. The motor never really gave me much thought, as there a lot of great motor builders out there, many who are here on OSO, I do have a couple in mind. As in the other thread the drive is were I am concerned.
