Took my Rotary Lotus out to WSIR. with Speed trial. Advance group only have about under 15 car or. So still some Traffic. but is not as bad.......

Today I also Rent MAXData Data Log system... Why ? Because My VBox Mini is not here yet..... Two thing really suprise... First Is my Top Speed....... Can you believe I only have 110 top Speed........ From Turn 6 to Turn 1. I am in my 4th gear between 7500RPM-6000RPM. but it wont get any faster no mater how hard I try..... Mbe this is A Down side when you own a car only have 160HP and have CD(drag coefficient ). that is mre then 0.5.....

Sec is How fast I can turn into Turn one. I just need to tap the brake, dont need to down shift. My Enterence speed is about 89 mile , and pull 1.30G...

 

The data log... really help me a lot. the two session I use it... I pick up 1.5 sec....

 

My best lap time today is 1:34.xx at moring. and 1:35.03x( althought I feel I drive a lot faster but I think the weather and track condion. prevent me to go any faster.

I think 1:35 or so is a very respectable time, especially with a 160hp ride. Some of the better drivers I know did around 1:32 in a NASA Enduro but with maybe 200+ HP.

 

As for the 110 mph on the very long straight in Willow Springs....it does not sound right and your GPS datalog may be in error. My only comparison is a GPS log that I took at the Cal Speedway with my (un-dynoed) approx. 180 hp Birkin. The top speed was there 129 mph (@6100 rpm in fifth) at the end of the NASCAR oval portion. And that even with the air brake (windshield) in place.
