Congrats Derek! I saw the run from the starting line, car hooked, went straight and pulled like a freight train!

Unless ATI has the diameter of the 10% OD lower listed incorrectly, you're at the limit of the KB SC speed at 7000RPM engine RPM with your last pulley combo according to KB's website. Now given the fact you aren't turning the 7000 RPM in the 5th gear. You could short shift it in the lower gears and stay under the blower max RPM limit and be able to twist it harder in 5th gear at the end where it counts.
Innovators West shows the 10% OD as 7.95" in diameter, where as ATI lists it as 7.81". Somewhere somebody has the diameter listed wrong for the 10% lower, yet both have almost identical diameters for the 15%, 8.12" (ATI) versus 8.13"(IW). But both 10% lowers are twisting the SC above 18,000 at 7000 engine RPM. I don't know how much abuse these SC can take and you may be able to twist it to 22,000 RPM and without a failure. It creates more heat, but you have the cooling system to handle it from what your saying. Van would know how far you can push the SC and tell you whether its going too far or not, I'm sure. Is a bigger blower better? A good question. Time will tell at the next event. If you can control IAT2 at the big end with the smaller blower and not worry about a structure failure of the gear drive assembly, bearings and bearing plates........I say go for it.
I thought that was the reason for the second gear launch. I figured this allows you to get to a higher road speed with a lot less drama in a shorter period of time and ground covered versus using 1st and having to shift to second. This would give you a better opportunity to reach top speed at the mile.
In the video.........you made it look very easy to do.......FANTASTIC JOB!!!!! I enjoyed watching, Thank You for sharing

Envy is a very ugly thing Derek....I don't know you, but I want to congratulate you on your run at the mile. Very impressive! Jon
Lol he went 11's at 143 in the 1/4 can't drive so he did the mile..
Nice job Derek! Any plans to see what it will do in the 1/4?
Badilac is now on vacation.
Congratulations! Very Impressive. What is required as far as safety equipment on the vehicle for this speed run?
