Vortech head unit change
Steve,
I am thinking of upgrading from the V-2 T-trim to a V-7 YSi on my new SBC 434. I am going to run a solid roller. Any recommendations on a cam? The heads are the new AFR 235's, CR is 8.9:1, 1 7/8" longtubes, single plane MPFI with 72lb. injectors. T&D shaft rockers, 1.7intake, 1.8Exh. FJO Racing meth injection as well. Idle quality is important as this is supposed to be a sleeper 4DR sedan.
Also, could you PM me your best price for a V-7 YSi head unit, CW, straight discharge, satin finish, and a 10-rib retainer kit, please?
Thanks,
Jim

Because I will be switching back and forth from the YSi to my Whipple 3.3 setup which really likes the lower compression with the low rpm boost tip-in. If it were YSi only I would have gone around 9.5:1. I figure with those cubes even the YSi won't lack for lowend, maybe just give up a little crispness.

This is all I could find at the Vortech site: "V-3 Superchargers are not "universal fit." Each V-3 supercharger is configured for a specific vehicle. Installation of the wrong V-3 unit for your car may lead to a false dipstick reading which may cause under/over-filling of fluid in the unit. Either situation will likely cause unit failure. For each model, the remote oil drain hose port location, the dipstick port location and the actual dipstick length are specific to the physical orientation of the unit when installed in the vehicle."
I'd call.

I have a 427 and a A&A V2 Trim Charger with 6 rip belt and 3,4" Pulley.
On 2000 turns, I have only 0,5 PSI and about 400nm Torque, at 3500turns about 4PSI and over 800nm Torque.
My question is, if I upgrade to a 8 Rip Belt System with a smaller pulley, get I more torque an lower turns per minute or will be the torque chart the same, only with higher numbers?
I want at lower turns more torque, is this possible with pulley change or only with an ohter champer?

Thanks Steve found it. I checked the oil and it goes a third of the way up the dipstick, about 2 inches above the crosshatched area. Am I correct in assuming this is overfilled and that it why it is blowing oil out the breather?

I did not do the install myself, the shop did add a remote drain line, so I am not positive that they didnt add some or not. At any rate I am going to drain it and fill it up again to the proper level. On another note, is the bottle of oil in the kit a 4oz bottle?

I have about 550rwhp, thatīs Ok, but under 3000rpm to less and I want more power from earlier rpm.
This is my testsheet:
Do you say, with a smaller Pulley the torque-curve goes to lower rpmīs?

Max RPM for the impeller on an S-Trim is 50,000.
With a 3.2" pulley, 7.33" crank, shifting at 6300RPM.. you will be at 52,000RPM on the impeller.
