I have seen posts before about everyone posting their times.

I am curious as to some of the numbers. Most important, the MPH at the end.

Mark.

Without the intake mods, stock suspension, and 2.73 gears I ran consistent mid 13s at about 101 mph. Haven't been back yet to try out the new combo.

I find your timeslips interesting. Your 87 Formula 350 13.94@96.67 and 98 Z28 1LE 13.15@107.59. The MPH is way higher in the 98, rather the MPH is low in your formula.

This is kinda what I was after as far as numbers.

Is it safe to say your forumla has lots of low end power, and kinda weaker at the top end?

That is correct. The Camaro has a pretty flat torque curve and revs easily to 6200 rpm. But it has a stiff suspension and I had problems getting it off the line. I haven't dyno'd it yet, but the Formula makes loads of torque down low and also has a flat power curve, but it dies at 4600-4700 rpm. The mods on the Formula so far have been to get the most from the car (traction & ET), then I hope to start adding more power. I figure when I'm done the Formula will also be running ~108 mph, but running 12.7 or so. The other night at the dragstrip the Bird beat a newer LS1 WS6 Trans Am. It was an 1/8 mile track. I hooked well with a 1.98 60', to his 2.45 60'. He could not make the difference up and I won by a couple car lengths. Of course he would have pulled me in the 1/4. Here are the 2 runs side by side. You can compare the times going down the track and see how the runs went.

It was 100° the night I ran the 13.15 in the Camaro and about 40° when the Formula ran 13.94. There are 140 some runs in my Formula documented here

all of you guys with 90 model cars you have the 10 bolt. I know my 90 iroc has the 10 bolt and i heard they al swiched over to it. Then agian i have the 12" rear disks on my car too. my times are in the sig. I should run much better than that when i run agian. I have pulled some cars up top that ran 103+ in the traps. so i should get some better times and trap speeds.

"best corrected" ?????? what elevation are you at??? what are times before correction?

 

i think that pass was a 14.21 or 14.31 @ 96.XX. I am running at 3500 ft. I have been told that the track i run at is the slowest track in texas. it is never preped they just open it up and let people run. i did not correct for calculated air density. if i had done that the time would have been a 13.2 i think and i really don't think my car is capable of that. I think that 13.62 is representative of what my car is capable of at sea level. I have run a 13.23 on g-tech while at sea level.
