Went to hrp yesterday and got 2 runs in the whole day lol.
First pass was the best even though I spun a little. ET Streets were @ 15pounds....will try a little more air next time. New PB & this was n/a as well.

60...1.801
330...5.363
1/8th...8.387
mph...81.14
1000...11.044
1/4...13.315
mph...99.14

Also, if anyone has an idea as why I am losing et and mph up top let me know. Seems to be 2/10ths & 2mph slower compared to the 1/8 et & mph.

 

Nice times! and your losing on the big end BC its a truck, My old silverado went a 7.71 @ 90mph in the 1/8th and a 12.04 @ 114mph 1/4 where as my camaro went 7.76 @ 92 mph in the 1/8th and 11.84 @ 117mph in the 1/4. And both were 60' in the 1.7s. Aerodynamics own

 

good times bro!

how much gas did you have in the tank?
when i run at the track i have at least 1/4 tank of gas, if not it bogs on the top end.

 

Well, if you calculate out your 1/8th mile 7.71x1.56 = 12.0276 and mph 90 x 1.25=112.5 seems you are right on...even a little better on the mph.

Mine was 8.387x1.56=13.08 and 81.14x1.25=101.425. I know the calculations arn't perfect but they tend to never be a couple hundreths off.

 

a little more than an 1/8th...hmmm that might be it.

 

here's the vid...It's the first race...also 05FAMILYTRUCK is in there and a couple other cars and that ard truck.

I dont know if im just talking out of my ***, but didnt you say you are on stock manifolds? and if I not mistaken you cam/heads on it? with stock manifolds Im pretty sure you are hurting your top end? if you do have LT's then just ignore me!! lol..

 

No feels fine in the upper rpm. Recently changed fuel filter and pump.
Yep, still stock manifolds...stock heads though. What you are saying is definately a possibility.


Next time out I will try to keep more than a 1/4 tank and see if that helps.
