Texas Speed Twin Turbo Corvette - 1040 HP!!! Just finished up a customer's Z06 Corvette. Car is a TSP 427c.i. LSX engine with Precision Race Components 6-bolt LS7 cylinder heads, HP Performance twin 67mm turbo kit, Ram Automotive dual disc clutch kit, and Aeromotive fuel system. The customer purchased the car from Florida and had it ship directly to us. It baselined at 445 rear-wheel horsepower, and in this video the car produces 1,040 RWHP and 904 RWTQ on 15lbs! I think he'll be happy for a while! 
Enjoy!

Amazing. I have to say to have an honest 1000+ rwhp street car is a car of legendary status !!
Just curious what the dip is at 3800 or 3900 rpms? Can it be tweaked to eliminate the ever so slight dip?
Great job.

Could be some tuning quirks due to the boost-referenced FPR in addition to the Aeromotive fuel pump voltage controller (low voltage to high voltage set to 2800RPM). That 2800RPM setting may be too high, everything happens so fast on these types of pulls.. I used a House of Boost fuel system with the in-tank Aeromotive Eliminator fuel pump. Very nice system actually.
