YSi Install info needed please Looking into FI still and seen John post up on the YSi, but he has no PS, AC etc.. Is it necessary to ditch the PS or not? I read that the YSi can be mounted in the Vortech G trim kits bracket, and I havent seen any other pics so wanted to see how much fabbing/modification is necessary to mount the YSi. I know the fueling requirements, forged engine, trans, and rearend. Just more so for the actual dropping of a YSi into the bracket and onto the engine.
Also, how does the T Trim fit into the same bracket? Its physically smaller then G or YSi trims but is in between them in cmf discharge, and 10k less in max impeller rpm, so it shouldnt take the abnormally high rpms to max power like the YSi?
Seems less problems with the Vortech over the ATI, although the ATI/SDCE kit is rather attractive, solving the bracket flex, and tensioner....
*turbo/sc/turbo/sc/turbo/sc* ughhh.....

its goes like this. g-trim=small, no other head unit fits in that bracket. S and T will fit in the same bracket, but its not the stock one. RMCR (?) in Col. makes one...search to find members using it. They make a bracket for the up-top mounting of a YSi as well, there is a post on it in the forum right now. You can get cfm ratings on vortech's site and compare w/ turbo's or ati's stuff.
The vortech (v9 style) belt assembly is the best out there for the ls1...8-rib, good balancer/crank pulley, good belt wrap. However...its still a belt. Get a turbo if you have the choice and can get a good tune on the car.

The T-Trim and YSi-Trim will require custom brackets. You could take your base kit brackets and knock them off, and have a custom set made that fit the bigger blowers. That is what RMCR does. The downside will be whether you can fit either unit under your stock hood.
I elected to mount my YSi-Trim down there the 93-97 F-Cars mount theirs. Since our alternator usually sits down there I had to relocate that. I am not sure I could have kept power steering. I think I might have been able to keep a/c but I had already removed it four years prior. My car made 738rwhp at 6500 so it's hardly a high rpm setup.
