Exciting! Great video (My GoPro shakes a lot). Any idea how fast thru the uphill "S's"? Was 173 mph at top end of gearing or cld you have gone faster if you'd had more road?

Why sell?

Thanks Guys.

 

The video link still works from my computer. ??

 

Speed in the area of the uphill esses was about 140 at max. I know this because the engine was just touching its 7000 RPM rev limiter on the best laps. The video does not show this because I was sometimes lagging back to avoid traffic. I've temporarily lost the datalogger files because my office PC died. We do have proper backups but are still struggling with getting business stuff reloaded on the new system.

 

The car has over 500 lbs. of downforce because of the wing, belly pan and extended rear diffuser. It is actually quite stable when going fast. The camera was mounted on the roll cage above my eye level. From where I was sitting, the hill at the end of the fast straight was plenty big. I could not see the braking zone placards or approaching corner until cresting the hill. I admit it took more than a couple of laps to avoid lifting until over the blind hill. The location of the camera makes that hill look much smaller that it appeared from the cockpit.

 

My tire compound selection was way soft for the ambient temps. After about 1/2 lap they got very greasy. Think I'd have been quite a bit quicker with a harder tire compound. That was the first time I had raced with Goodyear Radial slicks. Liked them a lot (for the first 1/2 lap) but the R430 rubber was not up to the 100*+ air temps and sunny heat soaked track temps.

 

Top speed with current tires and gear is about 180 and limited by the 7000 RPM rev limiter. I could probably safely increase the electronic rev limiter without hurting the engine but max HP is at around 6000 to 6200. Shifting at higher revs would hurt acceleration and I've not found a long enough straight to use it. I've actually thought about trying Bonneville or the Texas Mile without the wing and much larger rear tires. Don't know if 200 MPH is possible but it would be fun to try.

 

This car is now For Sale. I've done about everything I can think of to improve it and it is time for a new challenge. Please check out the For Sale section of this forum and http://www.photobucket.com/stalkerV8
