Beginners question on Dyno run results

He was confident that there were a few more horsepower to be had. The motor is my stock block with all forged rotating parts. Callies 4" crankshaft, Mahle pistons and Eagle rods. The hydraulic roller cam is a special grind devised by Julio; the specs are confidential. The headers are 1 3/4" Kooks stainless and they are coated inside and out. The engine utilizes anti-friction and reflective coatings throughout. The motor was built to run strong N/A but to live indefinitely under a healthy shot of nitrous. I'll be racing it this season with a 150 shot. My DragSim computer program predicts 10.77 at 130 (all motor) on a typical summer day and that is allowing for 1/2 a second between shifts. Here's a link to the initial before and after dyno numbers. Don't be fooled by the peak numbers; the gains throughout the power band are very significant.
Thanks again to Dave, Julio, Roy, Rich and the rest of the Cartek wizards.

Just getting into the tech part of owning a Vette. Have completed th standard first mod of Vararam/Headers/cats/x-pipe and Magnaflow catback.
Stupid question on Dyno run -- I believe I heard Torque and RPM's equate to HP, how come the torque continues to climb yet the HP begins to drop? Also is there a site or thread were I can read up on this?
Thanks and enjoy the new motor

If my memory serves me correct I think John Carters 382 Drop Top only had a 200 shot on it and it went Solid into the nines.
It even won the Vett / Viper shootout at Atco beating another Cartek Car. Since Cartek built this car and built Carters car I see no reason why this car cannot do the same. JMHO

Both of John Carter's cars are in the 9s but they're running automatic transmissions - much easier to get the power to the ground. I wanted to go with a nitrous fogger system but Dave thinks that I'm already on the margins for a 6 speed car. That's just another reason that I do business with Cartek, they don't try to sell me things that I don't need.

Ruby6spd,
Best get that information directly from Dave. The Cartek web-site has prices for the short blocks but the coatings are optional.

Thanks Vince, I followed your posts with great interest when you were going through your build period. If I remember correctly you were looking to sell - whatever happened to that? It's hard to get back anything close to what we invest in these things, no matter how good they were built.
I'm going to re-post soon on my motor; Cartek has it up to 511/452 and it's making good power now all the way to the 7200 rpm limiter setting.
