It was fun while I used it but only made good power in the upper RPMs 3500-7000.
I made these pulleys
the smallest one was made just so it would boost down low, but I had to limit the engine RPM to 4000 RPM, anymore than that, it would over spin the blowers max RPM Of (IIRC 42,000RPM) which I did one time (forgot I had the smallest pulley installed @ the time
), then I sent it to Paxton for a rebuild of about $500.
I later sold the blower & brackets to a guy in Australia through Ebay.
My car was really more enjoyable to drive & had tons of low end grunt when I had 12:0 compression & 3, 48 MM Weber DCOE's
With the Paxton blowing through the same 48 MM DCOE's, it made a bunch more top end power, but the low end suffered because the Paxton could not produce enough boost down low & was limited by being only able to spin to 42,000 RPM.
With todays blowers, they can produce too much boost if need be.
One thing nice about the planetary ball drive Paxtons & early McCulloch blowers is that they were super quiet as compared to todays gear driven compressor wheels, (you can hear most all the newer style blowers even @ idle, my Paxton, you could not hear it @ idle.
The Paxton combo was enough to get my Camaro to run low to mid 12 second 1/4 mile times.
The 12:0 engine w/3 48 MM DCOE's was good for 13 second times & when I ran a single Carter AFB 400 CFM Cliffold intake & headers 10:1 4 speed w/4:10 gears was good for 14.30's.
All w/a 250 CI inline Chevy inline 6 .
The lightest I ever got my Camaro to weigh was 3000 LBS, normally it weighed approx 3300-3400 LBS
I miss driving my Camaro, one day though, watch out
