Do you want me to pick it up and test it for you?

I would also like to know. I am considering a stage 3!

I don't remember reading in the rules anywhere that decisions we make about our performance cars have to make sense. It's all about passion!

I've really been thinking about adding a roll bar or 3/4 cage. I still want to be able to drive it on the street, so full cage is a problem.

Any engine needs refreshing after 'x' amount of track/race usage. 40 hours is on the prudent side as pistons no matter who makes them only last so long. Many engines can go longer depending on the driver's habits but it's much cheaper to refresh it than to replace it.

I see a street only driven Katech engine lasting longer than you'd probably own the car (assuming the driver is checking oil levels, changing the oil and not stomping on the accelerator 2 seconds after the car starts while the engine is cold).

I don't have a pic of the power steering pump, but it looks just like the production pump on the outside. It doesn't come with a pulley.

We do calibrations on the engine dyno and Vector Motorsports handles the in-car side on the chassis dyno.

These are some pretty good answers. Thirty hours is our bogey for piston replacement in professional race engines. As duty cycle goes down it an be pushed more as you see, but 40 hours is pushing it for a car of this caliber and use. This car had a suspected cracked block because of coolant consumption so that was the initial red flag to bring it in. We're seeing our most hardcore road race customers crack LS7 blocks so that is another reason to go with the RHS-equipped Track Attack LS7 for the next engine.

Werks, 40 hours of road racing is like hundreds of thousands of miles of street use. If you drive your built engine on the street only and maintain it properly you should see well over 100,000 miles before complete overhaul.

If everyone starts getting Stage III cams I will have to move to the Stage IV (or maybe I will skip the IV and go straight to the V).

Thanks for all the congrats and I feel much better knowing that Mike has already shown the car around Autobahn. Maybe when I show up for Track Attack I can nap behind the wheel and let the car show me the line ☺

Looks like all the questions got answered. Tomorrow I drive up there and ill be waiting at Katech's door when they one Monday. A week from now I'll be on track again terrorizing the Audi and Porsche guys.

Here's a little on track video from her maiden event. This was at Summit Point main yesterday with the Audi club. All I can is WOW that motor is strong!

For comparison the head instructor had a tuned 997 GT2 on slicks. He was the only car faster out there but even after slowing to give him a point by on the main straight I was able to accelerate and match his pace for the rest of the straight. He was also a MUCH better driver than me so I tried to keep up as long as I could to watch. I'll try to dig that video out later and post it.
