I upped the pulley combo to a 8.25 and 3.400 so at 6500 rpm it should be putting the Novi at 55k impellar speed or the max the blower is rated at according to paxton.
On the dyno it was only able to get 14lbs @6000 before the tires would spin and smoke on the rollers which still produced 641 rwhp at 6k. I could really care less about the dyno numbers but I am concerned with the boost. It did have 10lbs at 4500 rpm. Little to no belt slip as I have a 10 rib with brace and the belt was freakin tight!
I figured it to be more in the range of 16 to 17lbs and now it has me questioning the air filter, intercooler effientcy, and cam as some where something is restricting the boost or is this the max that the novi can produce?
Set up is a 393 with canfield heads, super victor efi, 90mm t-body, 2" kooks headers. 6" diameter K&N cone air filter, X02 water to air intercooler and cam specs below.
Hyd Roller
116 lobe center
.603 lift with 232 @.050 intake
.578 lift with 250 @.050 exh
Any help is much appreaciated
