1/8 mile racing
 

Go to http://www.wallaceracing.com/accel-calc.php . They have a free calculater to predict it for you. I put in 3200lbs,465hp,and a 28inch dia. tire and it said 6.99 in the 1/8 mile. Check it out and I hope it may get you close.

Re: 1/8 mile racing
 

One thing you may be failing to realize, is that, that formula is rear wheel HP, not engine HP. There's no way a 465 HP engine can put a 3200LB car thru the 1/8 mi. at 6.99. There's between 15&25% HP loss in the drive train, realistically it take about 600HP to run that ET in the 1/8 mile, and a lot of other factors are also involved, tire slippage, trans slippage, 60' times, etc.
An 465 Advertised HP motor would be lucky to run 7.80 in a 3200LB car.

Fact ot fiction

Zip.

That is a good point. Now I realize why the numbers were always off. Thanks for pointing that out.

hi guy's, i'll throw my 2cents in also- i have a 68 chevelle 3385lbs w/driver-383 flat tappet -536-560 lift cam-power glide-4.56 gear -30x9 in tire -footbrake. best 1/8 good air-6.95@96mph-best 1/4 mile -good air 11.01.06.-120.85mph we guess hp to be 490-510 -w/ decent air. 5-900 ft above sea level-air up to 2000-2800 ft et falls to 7.15-20 1/8 mile-11.15-22 1/4 mile conv- stalls@low 5-s just another example to throw in the mix. thanks jim

1 horsepower= 33000 ft/lbs per minuete. or 550 ft/lbs per second. No more, no less. Just some horses make more horsepower than others.

dparker what does your s10 wiegh? i ran mine last weekend didnt run what i think it will. im going to fatten up the carb and try again it was running scary lean. i pulled the plugs and they looked like they hadnt been run. i havent had a chance to put mine on the scales yet. a 496 on 92 octane ran 6.82 at 100 mph breaking up all the way. i guess it did pretty good but i think it has more still yet

I recently traded my s-10 for a mono-shock dragster. It ran anywhere from a 9.08 151.21mph in the 1/4, and on alcohol to a 9.60 on gas at 7000ft adjusted altitude. Best 1/8 mile was 5.72. What compression are you running?

what about a 1.50 60ft 6.30 1/8 @115mph....... :lol: can anyone guess what happened??

looks like its spinning to me...a very sluggish 60ft for the mph and et

thats what we thought to start with.. but the track was good that day and had already been 1.40 on the 60ft..just befor that, when i got back home i was looking over every thing and decided to check the throttle cable, guess what!!! the thing was not opening up all the way. it had a lokar braided cable on it which was less that 6mths old and already streached. i took it off and threw it in the trash, made me a rod with rodends and now the pedal moves half the distance but opens up every time... dont know how long it had been not opening all the way,,, just need to get it back to the track to find out the differance..
