Bruce,

thank you for your explanation, it is appreciated.  i can see where you would be coming from when a person asks a broad weight question such as this as it would equate to HP and this does as well.  i like formulas and check the dream wheel quite often crunching numbers.   even with all the added seemingly unnecessary junk on the car, i can not see a blown 426 using kb block alum heads etc safely making 1100hp ( i know there is more to it then that general statement).   where figuring it will have to be underdriven a bit (12 to 15lb) to get the number. this of course is assuming the tune is correct. one nice thing is im a bean pole and only weigh 200lbs so money ahead there :D

Bruce, how much boost are you putting to your small block, rpm, etc.

mine was less driver--but it was a fun number

If I fill my chassis and tires with helium will it be lighter ? I just could not resist !!!

1100 hp wth KB block and aluminum head is nothing.Same engine use to be in 8000 hp TF car.   Same thing alky cars ran for years with 2500 to 3000 hp. My injected  TFX92,BAE heads should be very close to 1100 hp. and that bracket race combo. I would not  think twice about 2000 hp with that combo.

Depending on air conditions, my blower only sees 22# of boost whether the OD is 5% or 21% , it just cavitates at that point---which is good because its consistent, re-striping it takes time to settle in and become consistent and you wind up chasing the tune-up.  The only thing OD gives you is when the blower comes up to full boost, Lots of OD the boost comes in quicker where as low OD numbers you are further down the track. Lots of time gets eaten up during the start of the race and is the point of course adjustment to get down to the index number or slow down.
 Using a 33 x 12 x 15 tire and a 3.90 rear gear -- trap rpm is around 7800 @ 200mph with a converter
