[QUOTE="Robert M, post: 10493381, member: 9628"] Bill - I don't know if this is true, but I have heard and read it on several occassions that the centrifical blowers and the roots type blowers do not put out the same horse power numbers lb. per lb. of boost. I do not know the reason why? maybe volume differences?, not sure......... I can say that I have seen Vortec centrif's that do spec at 1000+ hp but the S/C's I have seen are larger units and they were far from being street or emissions friendly. What is your Vortec unit rated in boost, size, etc? The blower in the upper right of this post is the 3.6LC KB. It is rated at 800 rwhp. and 900 flywheel according to Roger at Shelby American. It is a step up from the Super Snake 2.8H that is at 725-750 (flywheel) and way larger than the Eaton that originally came on my car at 500 horse.<<All of this with OEM cast iron exhaust manifolds (no tubed headers) and still meeting emissions in the 50 states. Going beyond emissions, SA Motorsports is now building a 1000 hp Super Snake. One of the 1000 hp was recently sold to a buyer in the mideast. I can say that currently, even with my 2.8H level @ 725-750, the hp drops off quickly as the heat rises. When I install the 3.6 liquid cooled I am also going to install the Shelby Upgrade Cooling System which includes a new/larger radiator, I/C, dual fans and other associated parts. Without a correctly sized intercooler system, the hp is short lived when things get hot. When I was at the 40th, I stopped at the Vortech vendor tent and noticed that a 2000 Cobra R was on the cover of their brochure. I asked them if they made a kit for the 00R, they said no, but they had a 3rd party vendor who did. This was the brochure back in 2003............. [ATTACH=full]163368[/ATTACH] I must admit that a 2000 Cobra R would be much more exciting at these higher S/C'ed hp levels, but there is also something to be said for having these higher hp levels and pinning yourself back in the seat with the A/C blowing............
