Does anyone happen to have any performance data regarding the Vortech S/C aftercooled kit for 99+ Civic SI's? I've seen enough horsepower claims but was more interested in track numbers as opposed to dyno figures. Any input will be appreciated gentlemen. Thanx.

There's a user on here ClubSiRacer I think is the SN, he's webmaster over at ClubSi I think he went mid to low 13's??? Check for his username, and look at his old posts

Thanx Clayton.

I'd say at least .5 sec slower et than a turbo car with the same peak power. Centrifugal blowers don't make any midrange power!

 

It's just the intrigue of doing something a bit different from the rest that interests me. However, if I was looking for ultimate output, I would definitely go turbo.

we had one at our dyno day put down 234 at the wheels. Completely stock except for the s/c.
