Nice looking motor!! How about making an audio clip of it running on the dyno

 

... thank you, and will do, we should be on the dyno Sat. so i'll load some then ...

... this thing is super responsive, should make for a lot of fun in the customers 68 Barracuda ...

 

 

woo hoo ! nice one
that vacuum pump has struck my curiosity?
i want to know more...

 

My understanding is that it makes the rings seal better

 

makes the ring's seal better?
does it also eliminate the pressure that happens at high rpm's and the oil collecting around the crank
and 25 xtra hp how?
just by causing the rings to seal?
increasing vacuum in the block or the intake?
i have the extra belt slot on the pulley for the old air pump can that be used for one of these vacuum pumps?
i need to check this out at the summit racing and see what type of options are available?

 

Wow thats awesome power. Can you provide any info on the motor.

 

wow the price on vacuum pumps is crazy moroso has the cheapest $200 but i seen them as high as $890

 

... yeah, that's the down-side to a vac.pump set up, they are not cheap, this complete system from Jones Racing is a tick over 2K, but it is a complete system, alternator, vac.pump, brackets & hardware, hoses & fittings, HTD pulleys & belts, vac. regulator, drive mandrel and breather-tank, plus this vac.pump has a 5yr warranty also, only one on the market that has that, Jones is quality stuff ...

 

... the gaps in the rings lets small amounts of compression leak past into the crankcase, and at 7000rpm this results in a lot of crankcase pressure, the vac.pump actually turns this area (crankcase) from a positive pressure into a vacuum, about 7.5 inches on this setup, which is to be street driven, if it were a drag only deal, i'd turn it up to about 11-12 inches of vacuum, and the motor would make even more HP ... ... vac.pumps are a wonderful upgrade, if you can afford them ...

 

... here you go, it's a little loud, but she sounds sweet !!! ...
