Turbo-Bitchin' Thread. Was: What's the target power to weight for STU?

[Chip42]

no dog in the hunt, but no, he didn't use whp. he used 120 hp/l which you just stated was the estimated chp/l for STU. you assume a 15% driveline loss and you could just as easily have said 102 whp/l (120*0.85).

weight to wheel hp numbers following Greg's math (which is correct):
120hp/liter x 0.85 x 1 liter/1000cc x cc/1.1# = .093 hp/#, or 10.75 #/hp

And FWIW, 102whp/l is much more in line with STL, I don'thave a clue what one might actually see in STU

Be careful: "he" made that post in January of 2011, which may have been prior to "his" inclusion on the STAC. Or damned close, so a newbie.

[Chip42]

doesn't change the math. what "he" calculated in 2011 matches what the cat killer quoted as expected chp/l. I was simply pointing out that chris' assertion about the math was incorrect based on his earlier posts, dated 2013.

and THIS IT guy might think the options presented by ST look like fun but this IT guy has NO desire to see IT made into a "national" class.

I think the only reason any of 'us' would want IT in the National program is if it was managed the way it is now...by the Ops Manual. If it was to take the typical 'Prod Style' or now 'ST style' comp adjustments, I don't know anyone who would want the CRB screwing it up.

Granted that there were other records broken that weekend, but not in all classes. But, the STU record was set exactly a year ago by the same car and driver. So, if the reset weight to TIR chart was used, and he still broke the record, it would indicate that the same gap between turbo and naturally aspirated cars at the runoffs still exits as the N/A car's hadn't and anything done to speed them up.

A lot of the new lap records that weekend were in new classes, or classes that had been sped up. T1 and T2 are now both faster classes, and T4 and BS didn't exist a year ago. As for STU:

Jan. 22, 2011 Hoover set the STU track at AAA Speedway at 1:53.897
Jan. 22, 2012 he reset the STU record with a 1:50.115
Jan. 27, 2013 he reset it again, at 1:48.792

Looks like those STU turbo car adjustments are working.

That's why the Prof left STU and is now rolling EP
