I think Jeg Coughlin made a pass at Zmax in the Napa car. Low 10s@130ish is what I seem to remember.

The one's I've seen, and I've seen a couple, ran low twelves. I really don't think a NASCAR car out of the trailer could run a ten second time slip.
Don't forget, they are not set up for it. The motors do not make a lot of torque...they do make hp. It's apples and oranges.

thats why I ask. As I know there are no R5/P7 powered drag race car out there? I know there are one turbocharged R5/P7 truck but this is not also for 1/4mile
Just want to know or see vid clip from some pure dragrace car ( not dragster ) on 1/4 mile.
Here is lot of discussions :"how, I quess etc." but no-one what I heard have been in quater mile in real life.
Just that I have now 845hp/555TQ R5/P7 motor and Iam searching light body for that ( around 2400-2500 lbs total weight )
Why I still ask "how much it would run" is that one guy say R5/P7 dont have enough torque for low 9 or even high 8 seconds, second guy says - no problem at all just good converter and correct gear it will fly....
Also guys told to avoid "big rear wheels" and stay with 10.5" slick. But those two rollers what Iam watching right now is with narrowed rear end and with "big slick" ( 32/16-R15 )

You have to remember that your tracks are nowhere as good as in the US, maybe you don t need 16 inch slicks but 10.5 are to small for you a small low torque motor need to be launched hard, you can t do that with small tires on a lousy track

If you have 845 hp with a 2400-2500 # race car all you need is the right converter and gear and you should make it into the 8's. I also agree you will need a big tire to hook.

Right converter and gears and it will go just as fast as an equal HP big motor. You just have to keep it in it's power band. HP is HP you just have to multiply it with gearing to get the TQ at the wheels and TQ at the wheels is all that matters An over the road diesel from an 18 wheeler might make 1000 ft lbs TQ and 300hp but still would not be any faster than a 300hp gas motor in an equal weight dragster if both combos were optimised.

Those cup motors do not work well for drag racing. If you notice, you can find them on ebay pretty cheap, around 7g. There are guys who've tried to make them work in comp eliminator, in dragsters and altereds, and they have given up. They've tried different camshaft profiles, converters, etc, but the design just does not lend itself well to the drag strip. The reason you can buy them cheap is that they are for one application only.
It takes more than horsepower to drag race. Those motors have a real short stroke, short deck, and make no torque or mid range power. They make 800+ power at 8500 rpm, but you don't run a drag car 8500 rpm beginning to end. The torque and mid range is equally important.
It's just a matter of application. Those motors are built for what they do, and they do it well. They run wide open for long periods, and make good power. But, they do not lend themselves for drag racing.

Thought there was already someone on this board that had a P7 motor in a dart that was going in the 9's, IIRC.

I'm not hammering it into the ground....I'm just stating facts. Those cup motors are specifically designed and built for wide open laps around a super speedway for extended periods. That's is the reason for their existence.....that is why you can by them very reasonable. The market for a used one is very limited.
It's apples and oranges.
