I looked around on their website (www.vortechsuperchargers.com), but could not find it. It might be 4:1?

yeah I checked their site and could not find it either. I am just trying to see how far I can stretch this blower before having to switch out to the YSI

Vortech rates the T-Trim for 825hp but I've seen 700rwhp dyno numbers here and there.

I figure I can easily break the 700 rwhp mark with an intercooler and a couple more lbs of boost as long as I'm not overspinning the blower. I'm only making 10 psi right now, so I just need to do a little math a see what I have to work with

I'm actually not sure, I've lost the sizes and was going to find out when we take the motor out this week. Before when the cog system was on the car we had it calculated with 13PSI that it would be slightly overspinning the blower.

I recall the T-Trim being okay for 18-20 psi, but you can always check with jsnee@vortechsuperchargers.com for any in-depth questions.

I think it says it will go to 26psi, but it says max impeller speed is 55000 rpm. I don't think I could make more than 12psi through my 396 and not overspin it. When we had it at 13 psi with the cog I believe it was right 55500 which was slightly overspinning it. But with some miles on the blower now I don't want to push the issue
