I'm currently on vacation in Michigan while the Vette is having the FI installed back in Oklahoma. While I've searched a lot, I can't find the answer so asking my knowledgeable Vette buddies if they have some input. Install is on an LS1, built A4 and ECS diff. I'm going to have tuner set rev limiter at 6500 and shift at 6400. The Novi is rated at 60k rpms (but some guys overspin em). What would my Novi rpms be with a 3" pulley and IW 10% overdrive balancer at 6400 engine rpm?

Thanks....

DOUG @ ECS

At 6,400 RPM you will be at 59,733.333333333333333333333333333333333 3 blower RPM.

u wont have any problems with a 3" pulley to 6500 rpm if thats your concern...I use a 2.75 and 10 overdrive and spin it higher than that with 0 issues so far
these ysi blowers love to be spun hard from what i seen

Appreciate your reply Doug. Your answer is slightly vague however. Could you be a bit more specific???

How many 3's does belt slip knock off

DOUG @ ECS

Easy computation;

Pulley diameter, multiplied by PIE R squared, divided by a properly tensioned belt, with ECS thrown in any place of the equation = no belt slip.

Or like this if you prefer;

3/3.14 X PTB/ECS = No belt slip.

Glad I could help
