    Aside from some dyno day SNAFU's I was happy with my numbers and tune. My car weight was 3140 at the scales that day and temp was @ 60 degrees. The Mustang dynamometer 1st run to 5800 rpm showed 385 rwhp and 524 ft-lbs torque something was amiss as my data log showed boost drop from 14.5 psi to 8 at 4300 rpm major boost drop on that run was a mystery as this had never happened before. Second and third run proved better as boost stayed flat at 14.5 psi. The last run resulted in 431 rwhp and 500 ft-lbs torque. The killer thing was my car made 460 ft-lbs torque at 2300 rpm. OK here goes the major SNAFU in all of this we never had any fan on the engine or intercooler during any of the runs I totally forgot and so did the dyno operator. I didn't even realize this until we had left the shop, what a bone head. My logs showed the ACT temps more than doubled to 130 degrees. Even with the belt slip and no fan I'm still pleased with how it performed total timing was 21 and my AF was 11.5 safe and sound. I hope this video works for you.

    You should call that thing the "Screamin' Squid." That sucker is badass. Make the guy next to you wet his pants when he hears that thing wind up.

    Nice I like that.....

    Here is my dyno sheet from the last run. I like the torque curve coming on at 2300 rpm. I'm not sure what all the peaks and dips are in the begging of the run, maybe belt or tire slip. Also the whole curve seems kinda jagged any thoughts.

    Here is a screen shot of the data log from the dyno pull above A/F was 11.5 for most of the run accept the end it upped to 12.2 boost stayed up to @ 14.5 psi.

    I suspect the jumps in the graph are belt slip. What's your pulley combination and how many ribs are they?

    I just did a 6 to 8 rib conversion and went with larger 7.5 inch custom amde crank and 2 3/4 blower pulley. The dyno operator thought it was more likely a traction issue on the drums with that much torque so soon.

    Looks very strong. I am sure it will looks quite a bit better with fan or meth hooked up.

    Here is a little drive video to get the sound of the KB wine inside the car. Notice any time I excelerate I'm giving 1/4 to 1/2 throttle no traction in 1st second 3rd gear, that's what 460 ft-lbs torque at 2000 rpm does. Sorry for the crappy video I used my digital camera taped to my pass seat back and the roads are bumpy too. Anyway here ya go.

    I got a solid 17.5 PSI today with a 2.5 inch 6 rib pulley and belt, and no belt dust. I just couldn't wait for the 2.5 8 rib ASP is making me. I also am re-thinking this belt slip issue with the KB's and the route I was going, I'm not sure that belt slip really was an issue for losing boost. After talking with Carbinite Racing about the massive dust and belt destruction I found after using there pulley they now want me to use a manual tensioner. They are saying I need more tension on the belt and pulley to stop the belt destruction issue. I think this is a recipe for disaster as the KB drive system is not made to be direct drive so to speak. According to KB tech the friction drive system needs to have some slip to absorb shocks from the engine loads. The rotor timing and close tolerances are protected this way. Anyway once I will get the 8 rib 2.5" pulley I can compare with the 17.5 psi I got with the 6 rib. Its nice to know that the A2A setup can tolerate higher boost levels.

    I tought I answered that. The KB and the drive system cannot tolerate the stresses caused by any system that would not allow some slippage. For one the pulley is fastened to the drive snout with one large bolt in the middle. Its the friction or clamping force of the two matting surfaces by that bolt the drives the supercharger. There is no keyway of sorts that connects the pulley to drive snout so if too much stress is put on that bolt it will shear off.

    I like the concept, and its definitly a cool idea, but seems like a whole lot of work for the ammount of power your making.

    Still, i bet its a blast on the street. Sounds alot like my lightning did
