SVO blower is a good blower for those that know. It won't produce max numbers like a centri(Paxton,
Vortech, ATI) or Lysholm screw(Kenne Bell).
300-320 rwhp is possible with stock non-PI heads and proper other parts. This is where most centri blowers fall flat as well.
Aftermarket fuel pump, aftermarket MAF, 9 or 12 lb pulley, headers w/offroad exhaust, ported blower intake, cams and tune will hit 300+ rwhp no problem. All this can be had with a used blower for < 3000$. (My blower is for sale, I also have a Pro M 80mm race MAF + some of the other parts )
Ported PI heads and cams will take the SVO blower to 350-400+ rwhp.
Roxanne Shepard, 2 Cam Sam, and others have made these numbers with the SVO blower. I doubt there is much left in the blower after this point.
It also looks kewl, and is different from the rest of the centri clones.
Keep in mind, Roots/screw blowers make streetable horspower. Off idle to 3500 rpm will beat a centri any day.
SVO blower is based on the M112 Eaton blower, same blower size that is in the 03 Cobra and Lightning. These cars make 390 hp.
Yep, the SVO's intake manifold is a drawback as well as not having an intercooler. The intake can be opened up by porting companies, and the temperatures can be lowered with a proper cooling system and water/methanol injection.
When I ran my blower, I ran TR6 plugs, Royal Purple Purple Ice, 160degree thermostat, and I never had a problem in Dallas heat. Temperature gauge was lower than stock.
