Has anyone got the maximum speed the ISF reaches through the gears just before redline as the car is so fast sometimes you cant keep up with gear V speed . Normal speed not theoretical cheers.

Thank but this is only theoretical, just want real speed though the gears.

What do you mean "real"? The gear ratios are what they are. It's impossible for the car to be travelling at a different speed than that which the engine is spinning the wheels at (assuming you have traction)

The other assumption in this is that you are using stock tire size diameter. If you go to larger tire diameter you will go faster by an amount proportional to the percent increase in diameter.

178 mph @ in 6th gear @ 6750rpm 260 mph in 8th gear dam these cars are(dyno) fast may be this is right TY.

Wait, you can reverse up to 80 MPH??

I built that spreadsheet from an original by Dan Masters of Alcoa, TN. PM me if you want a copy.

I also have a basic engine analysis spreadsheet I built entirely myself, a couple of turbo sizing spreadsheets I've collected, and a piston kinematics spreadsheet that's very handy for understanding the relationships between rod length, stroke, and piston acceleration. A long time ago I planned to bring them all together for a single engine analysis spreadsheet with theoretical power and acceleration curves, but never finished the project.

Yes, indeed it is possible. Not trying it any time soon, but you could for sure.

Thanks Lowbux I would love to see the difference in speed in real time down the 1/4 mile cheers.
Just checked utube and these speeds at 6750 are spot on TY.

I will the next time I get a loaner/rental.
