Not trying to stir the pot.Just started working on the next project that will come after the 72 camaro.Started designing the suspension for that car.So I need to plan on how much HP we will be needing.Kevin and I are wanting to build a real nice car that will run close to the front runner's at these event's.

Woops, my bad What year car? Real nice PT or race car? You've installed subframe connectors before right? Subframe connectors will take some of the flex out of the body.

A quote from one of my heroes Mark Donahue-

The Porsche 917-30, whose 1100 horsepower, the SCCA bitched, was killing In the Can-Am series. Donohue disagreed. “We’re far from having too much horsepower,” he asserted. “My definition of too much horsepower is when all four wheels are spinning in every gear.”

If you can control it is not too much HP. I would say there is a point of diminishing returns. The new blower engines are like big DC electric motors. Torque on demand. I have driven big twin turbo engine on tracks and the turbo lag can be tricky. I really like the power delivery of my blown 427. It is very linear and tractable.

I modeled another 100 HP in my car and was only worth 0.3 of a second at Spring Mountain Ranch due to the size of the track.

With all due respect,

Keep in mind, I dont think many of us could hold a candle to Mark Donhue's skills. On the same note, tracks like Thunderhill love the high horse power but tracks like Infineon and Buttonwillow would probably fare better with less.

Before anybody decides to go big horsepower, it would be best to be sure you are effectively using all hp that you currently have.

It takes a lot of time and tuning to get our cars to drive effectively on a road course and then you have the other variables such as tires and aero.

It should be a real nice (PT/racecar.)I do know what sub frame conector's are.I have seen photo's of them being installed on DSE's web site.There coverage is great.

DSE makes a great set of subframe connectors. I really like the straight through design. I bet this next car is going to be very cool. When you going to spill the beans?

I honestly believe an LS2 with a cam headers and a tune from speartech would be capable of being pretty competitive if you really wheeled the car hard. although the LSX 454 or LS9 would be really cool an LS2 with top end work and headers would be capable and help keep the cost down.
