Finally installed the SLP 25% underdrive pulley and vararam
some of you might have noticed me abusing the forum with questions pertaining to the slp harmonic balancer and the vararam. so here's my chance to add some info regarding the two.
i finally got around to bringing the vette in to get them installed this week, and man, what a difference. the new balancer and intake makes the car feel so much more responsive, the car now idles really smooth and feels nice. sotp meter say's about a 15% increase in power
the only thing I'm not too happy about is that the balance makes the car just a little quieter at idle. and battery voltage with all lights on dropped to 12.7 vs 13.2.
for any one looking to do the powerbond/slp balancer the belt sizes are 77.5" for the main belt and 41" a/c.
as for the vararam, the quality fit and finnish is pathetic, but it does its job well at sucking in air and thats all that matters. would i buy it again? HELL YES!!!!
so all in all, this project cost me $1100 out the door(parts, labor etc.). a little steep if you ask me. but it wasn't an easy task, and the balancer was wobbling really bad and had to get taken care of.
also would like to thank Dennis at DDMODS for the parts and great price

i am going to put one on sooner or later but it is going to be with a cam. figure the shop quoted 900 for a cam install and the balancer is part of that.

so i got around to washing her yesterday and just for the hell of it i stuck my hand in the intake opening to see if any water had been collected, and man was i surprised. the was allot of water that had pooled in the ducts. i thought the Vr-b2 was supposed to have a water out air in design? this car will definitely not be driven in any rain after seeing and physically feeling the puddles of water in both duct openings. scary stuff i tell you. imagine at the rate of 65mph how much water would or could be sucked into the engine. i do not recommend this for daily drivers. luckily my car is a nice weather/weekend car only.

Water issues
I installed a VaraRam on my last C-5 and it did make a notible difference I also had no water issues even after heavy rains or washing. I'm in the market for another VaraRam for my current C-5. Should have removed the one I had on the last "5".

As DBL98COR did, you could install an overdrive pulley on your alternator and have stock amps. Another alternative would be to upgrade to a hi-output alternator, but they cost $550-750 bones depending on the amperage. However, if you are not running much extra draw from stock, you will probably be just fine.
