Quaoting from a Dave Butler ("dangerous") thread:

"it ran 10.93@122 with 220hp and 1785 lbs of weight"

That was RWHP, so with and extra 115 lbs weight you would need something around 250 RWHP; oh, and about ten years of chassis and gearbox development, together with lots of light practice.

I just tried several online calculators, which gave wildly different results from 280 to 400 RWHP to run 10.99 with 1900 lbs.

yeah heaps cheaper I do 10s on the 1/8 mile with my road registered oval with everything in it with 68hp.
& even a 9.6 on the 1/8 mile in my old 54 still heaps of fun at not the huge expense

10s on the 1/4 I'll leave that for the serious drag racers.

This one has now changed and shows much higher power than I have found in the past,
but it is an easy way to work it out.

It important to note that it is easy to run the MPH if you have the power,
but to run a 10 second pass easily, will need a lot more power,
unless you can get off the line well.

As an example, you really need to be in the sixes ay 97+mph on the 1//8 mile with 60 foot times in the 1.4's.

Thankyou everyone for your replies... How much drivetrain loss do we expect in a vw sedan when converting from flywheel power to rear wheel... Many different sites claim as a standard from 10% to 20% .... which would you say would be more likely for our vehicle type
