Re: NHRA 283cid Stocker Engine
I saw on one of the posts what I assume to be dyno results up to 8000, any idea where he shifts and traps at? I have a theory and am curious how close to truth it actually is.

meanwhile , you might be interested in this new "old" year 2011 NHRA ProStock info i just received
on Shift and Cross RPMs ... a decent Run for 2011 ... Qualified in lower half of 16 Car field
RacePak Data every 0.001 of a second :
NHRA ProStock
Year= 2011
6.640 ET at 209.20 MPH
every 0.001 of a second
1st-2nd Shift = 9968 RPM falls down to 8344 RPM
2nd-3rd Shift = 10627 RPM falls down to 9171 RPM
3rd-4th Shift = 10488 RPM falls down to 8805 RPM
4th-5th Shift = 10456 RPM falls down to 8468 RPM
10461 RPM Cross
somewhere around these Trans Gear Ratios : ???????
2.6099
1.9396
1.5539
1.2560
1.0000
the Geometric Progression Trans Ratios would be :
Geometric Progression Ratio = 0.78676319
Gear 1 = 2.610
Gear 2 = 2.053
Gear 3 = 1.616
Gear 4 = 1.271
Gear 5 = 1.000

On a side note What I've done is use my old version of et analyst as an et predictor for bracket racing works great.
