I should have done that, when I installed my cam. Have you had a chance to go back to the track since your rebuild?

How long have u had your D1SC on the car? How many miles? I've been reading people complaining about prochargers on the street leaking oil at the impeller seals. How's yours been?

I have never heard that. I have had mine for two years and about 12,000 miles daily driver with no issue. I Love it.

Nice. Glad to see u enjoying your procharger. By far my favorite blower but I'm only used to using there race blowers. F3's and bigger. Built motors and crew chiefed for my buddies pro street mustang. Small block ford on alcohol making 50 pounds of boost. Best we managed was 6.50 @ 212 MPH. Retired from racing and now I want to play on the street!!!!

Can't decide between a procharger D1SC, Vortech YSI or Maggie 2300. The catch is, which ever blower I get it has to be able to run a cog drive reliably with a manual transmission on the street and not blow belts on violent gear changes. I've been told with the centri blowers running a cog on the street with a manual transmission really depends on how sturdy the brackets are. If there's lots of movement you'll blow belts all the time on hard gear changes. So far the Maggie is looking like the most reliable with a cog drive. I gotta have the blower whine sound!!!!! Need to find some guys with centri blowers and cog drive and find out what the real dealio is??

I hear some have ran the YSI with a cog on the street. Not sure about the belt life. How much power are you looking to make? Ysi will make over a 1000 no problem.

Just to clear this up...gpi ss3 VVT cam gained 110whp no pulley change and saw 10.7 psi at shift of 6400 before and now see 10.6 psi at about 6800 rpm shifts. There was no pulley change needed. A proper spec blower cam will do what u ask it to do. The cam was spec'd to not bleed off much boost...also steering midrange power since its a centri. U need specs up front on a cam before you buy.

For now and probably the next 3-5 years between 600-650rwhp. Then when I have more money saved and I feel I am bored of the power I will up the boost. Then if I blow the engine I can build a new one without any down time. If I'm content with 650rwhp for the street I will just save my money

Anyone else use VVT cams with a blower? It seems like the night fury and JRE blower cams make the most power but I don't see why VVT can't do the same

Milkman...I gained 110 on a VVT cam...that ain't too shabby...lol. I don't see gains like that very often especially with a VVT cams power band advantage.

CMS (Cunningham Motorsports) Custom grind cam for me!

The guys at PFAFF Racing Engines (who built my engine) were so impressed with the power it made they now specify something very close for their sand rail engines. Makes awesome power, but equally importantly, excellent torque across the rev range.
