Depending on the route you go fro 900+ horsepower, I'd say anywhere from $20,000 up to $40,000+. Depends on the parts you use and how deep in the motor you go for reliability.

MPD S475 single kit
dual fuelers
100% nozzles
airdog 2, w/ airdog upgrade
stage 2 valvesprings
ARP studs
all billet suncoast internals, suncoast HD TC

914 HP on fuel, never got a torque reading
Track times would have put that number higher, but I had bad PW issues.

I bet that thing is a monster on the track.
I'd venture to guess, track times prove more then 900hp!

Thanks Shone. Best time was a 11.3. After every pass we did times kept getting slower and slower. Craig found that the PW was only maintaining 1.74 on Extreme Race. Definitely had 10's easily.

Very nice!! So if a S475 will make 900, wonder what a compound kit with an s480 would make in a compound kit, with the same fueling.
