2400 even, thats all you can get out of a BSP s2000. If i spend another 7 grand(which im not), i could claim 2350 from brakes and alternator plus two or three carbon pieces around the intake side. Note that this is fully fully prepped and with a quarter tank of fuel (no it doesnt starve anymore at that level)

How are you countering fuel starve, Robert?

stock tank. not stock fuel pump, nor stock number of fuel pumps... may or may not be a few check valves in there also...
All carefully within the rules

Just curious. Luckily for me, the Z can run on 1g of gas with the stock tank and not starve (except on concrete where I run around 2g).

Good Job Robert! I would absolutly love to see a full master list of everything you did you reduce weight! Thats a great number! About 150 LBS lower then the STR build!

My XP car was 2116 lb at the Blytheville shootout this year. The change to 16" wheels and bias plys should net another 30 lbs or so. Bryan can confirm this number.

I would love to get my car close to Bryan's 1900 lb.. But, with the cage and supercharger bits it's not likely.

The new larger supercharger should make up for the weight though.

I will try to get some new photos up to show progress.

Very impressive Robert. Now lets add a few more carbon pieces and supercharge that thing to take on Carter and the rest of the FDs in SSM.
