Our new Pontiac Crank mandrel drives are
custom CNC machined to our specifications by Aeorspace Components out of 6061 aluminum.
The mandrel includes the following features:
Mandrel bolts directly to harmonic balancer -
You use your stock crank bolt to bolt your harmonic balancer to your
crank. You no longer need to use mandrel systems that use 5 to 6 inch
balancer bolts. Your balancer is now reliably retained by a separate bolt.
Some harmonic balancer manufactures will not warrantee
their balancers if you use such a crank mandrel system.
Works with ALL Pontiac harmonic balancers
with standard BBC or Pontiac 4 bolt patterns AND crank
triggers!
Three 3/8 - 16 bolts not pictured but are included with the kit
Dual pulley bolt pattern – has both conventional 4 bolt Pontiac pulley pattern and the 3 bolt big block Chevy bolt pattern. Comes with cap screws to fit both 3/8-16 for BBC pattern and 5/16-24 for the standard 4 bolt Pontiac pattern.
FULLY ADJUSTIBLE!! 4 different locating spacers help with belt alignment. We can also custom machine spacers for you based on your spacing requirements. - Call for details
The standard Pontiac crank mandrel drive system
comes with the mandrel, 1 - 3 inch deep grove pulley, 4 alignment spacers, snout cap
and bolt. 4 inch pulleys , gilmer
pulleys, and additional spacer kits are also available separately. See
below....

We
offer four NEW complete kits at Tin Indian Performance.
One kit features the Aerospace Components Vacuum pump and the other three
feature the Moroso pumps (3-vane, 4-vane, and 4-vane enhanced).
All kits are designed to produce crank case vacuum
improving ring seal,
preventing blow by and leaks. The
system also helps reduces intake charge contamination as well. A must have item on any high horsepower race engine.

Moroso 3 -Vane Vacuum Pump Aluminum, Black Anodized - pulley INCLUDED!
These vacuum pumps are manufactured from billet aluminum and feature a precision-machined shaft, rotor, and bearings that will withstand the rigors of racing. They work by producing high crankcase vacuum, which increases power by improving ring seal, preventing blow by, and detonation. The pump also allows for the use of lower-tension piston rings for less friction. These positive pumps are much more consistent and effective than header-mounted evacuation systems. This pump uses -12 AN fittings. Pump mounting bracket is not included. Use part # TIP-002.

Moroso 4 -Vane Enhanced Design Vacuum Pump Aluminum, Black Anodized - pulley INCLUDED!
This pump comes with all of the hardware pictured above and allows for the most flexibility for adjustment when used with our Tin Indian Performance Crank Mandrel. Adjustment swing for the belt tension is a bit small at 1.7 inches. You just need to be fairly close with your initial belt length.

Frequently
asked questions:
Q: Why don’t you guys sell a cheaper system with a Ford style smog pump?
A: You get what you pay for! The Ford style pumps don’t pull near the vacuum nor do they last as long as the Aeorspace or Moroso units.
Q: How fast should I spin the vacuum pump?
A: Optimum speed is approximately 50% of the engine speed. (2 : 1 ratio). For applications below 8,000 RPM we recommend running the pump at 66 % ( 1.6 : 1 ratio). Using the 3 inch pulley provided with the standard Tin Indian Performance Crank Mandrel System will drive a vacuum pump with a 5 inch pulley at 60%. The 4 inch mandrel pulley would drive the pump at 80%.
Q:
Where should I plum the vacuum pump?
A:
We recommend attaching the pump to the front of the valve cover via a
threaded bung. This should provide
you with the best vacuum and best lubrication of your pump.
The outlet of the pump should be attached to a catch can that can be
periodically drained. Never attach
you vacuum pump outlet to your dry sump tank or to an exhaust collector.
Q:
How much vacuum do I need?
A: Most engine builders concur that maximum power gains are noticed in the 13” to 16” on a wet sump application
