What are you seeing for top speeds at the end of the back straight?

Thanks.

But Ron, in racerspeak 131 is "close to 140" :D

Kinda like the guy who once told me he was hitting 120 through T4 at Summit (the Chute) in his then-ITA MR2....um, ok.

Come on Earl, every (non-racer) I speak to gets told that my SSM is hitting "about 148" at the end of the front straight...

But you conveniently leave out the "KPH" part? :D

CMS is ~130 MPH in a legal ITS car .... :026:

134 here and I don't think I'm the fastest. The RXs are slippery.

Agree Jeff from what others have told me in an rx7 with all the stars aligned on the perfect lap you can be very close to 137-139.

That is just an ugly unfounded rumor to get weight added to the RX7. :rolleyes:

The Rustangs didn't even hit that last year. But, this year we've got new motors and new gearing. Screw that 5th gear stuff. I'm hoping for considerably better than our last CMS outing.

Now, Steve aint talking, but I imagine he's the guy who knows the best numbers, as he crews with the Huffmasters, and has probably seen the data.

I'd GUESS they hit 135-136 down the hill

I really could not tell you with the current car. I did not add the speed sensor to the Stack system with this install. I will pull some data and run it through the gear program and see what we were doing.

With gear program and RPM it gives me 135 2 places at CMS. I would not swear to that as it only takes a small change in RPM to be off. This was also in the draft with a green wedge opening up a hole the size of a tank. :D
