harmonic balancer's

[redneck zx]

Alright so here is my story I have a 91 TT, this is my 3 300zx but with this car i decided to do a full build take my time. my goal is to have the bottom end completed in 2 months so now i pose a few question's which harmonic balancer and pulley set should i run i want to keep my A/C but belive i will be running to much power for the factory balancer, im looking at 2 options right now and wanted to see what people have to say and what you guys are running.

I would imagine my car's bottom end info will be a factor so far I've got 87.5 arias pistons with eagle connecting rods, RPS Billet Aluminum Segmented Flywheel and ARP head studs. Once I get my pulley's figured out my block will go to the machine shop and my Rotating Assembly will be balanced. I would like to see around 600-700hp upon completion of engine. (also many other mods already done to car more to come Info upon request)


so my 2 options are

This should do it. I would n't cheap out on this if you plan on the build you said.

Ok so question for a balancer noob (8% overdriven AC and H2O/Alt pulleys and 6% overdriven PS pulley) can you explain this to me will this ware out the power steering, the A/C, and alt?

That small of a percent, not as fast as you think. They do make pulleys to change that so it is back to normal factory rotation.

Lets put it this was if you engine is running at 2000 rpms, the accessories will run at 2120 and 2160
3000 they will be at 3180 and 3240
When you are running 700hp, those are going to be least of your worries at 6% and 8%.
