thats exactly my point, all that and he ran 13.1 @ 108, compare that against david's car with a LS6 intake manifold running 12.55 @ 113 with comparable mods. (heads, intake swap, cam, etc) Biggest mistake people make around here is that they think buying the biggest of everything somehow translates into big power. I ran down a 04 GTO that runs consistent 12.6's with only a mild cam, headers and an intake and 3.29 gears. Still running the LS4 intake manifold. Can't wait to put some numbers down at the track and see what this thing can do, because it will expand the possibilities for me for future mods if it runs well.

you read that the track time was just with the ls6 intake he never went back to the track after heads cam and intake

Haven't found any off the shelf ones, only ones that fit 90mm LS2 tb's.

A FAST 92 is as easy a swap as any other manifold with the power steering reservoir relocate. I only had to cut off one nipple in the rear which LS4s don't use and I had to file parts of the manifold to clear the power steering pump. But otherwise it bolted up just as easily as the LS6 manifold did.

yeh i read the sticky threads, doesnt seem to be too bad, just debating about how to deal with the PS reservoir. I dont want a half mile of hose running around the engine bay.

Relocating the battery won't work anyway. The reservoir has to be higher than the pump otherwise it will back up. I ended up putting mine by my brake fluid reservoir. Routed the hose along with my brake booster hose. There is a lot of hose back there but it's mostly hidden and out of the way.

Have you noticed stock that the power steering suction line has to go up hill to the pump in stock configuration? .. it doesn't matter it's a hydraulic pump it sucks fluid and pushes it out

The reservoir is still higher than the pump. I can guarantee you that it has to be that way. I originally had mine mounted to my CAI and that's the problem I had. Did research, found out it's because it was lower than the pump, moved it so it was higher and bam problem solved.

Check your stock pics the line goes up. Your problem I can bet was how long your lines were which would be a huge problem trying to equalize the flow. The bottom of the resovoir outlet is actually lower from the factory

Post some pics of how anyone has theirs mounted. Could some kind of bracket be fabricated? I haven't looked at this at all, just wondering. Thanks

Probably what ill do is ill find a universal PS reservoir i can mount on the firewall somewhere and fabricate some hard lines to run cleanly along the firewall and over to the pump and lines.

Could something similar to this be used or would that not work?

not specifically but i could probably mount the reservoir to the rear cylinder head on the drivers side if i come up with a new style of bracket.

There just seems to be so little room behind the engine, I would think just keeping in the same general location although maybe bracket out a bit could be easier. I have no idea really , just guessing. Throwing **** to the wall to see if anything sticks lol.

lol ill figure something out, i just want it to be clean, and i want the reservoir to be higher then the pump, dont want to worry about issues with air pockets. magnasteer is noisy enough as it is.

Doesn't matter if the line goes up. The fluid in the reservoir is higher than the pump so it's still gravity fed. The pump may pull some fluid but it's mainly a gravity fed system. You also don't want the pump being the high point in the system because then air will collect in the pump instead of the reservoir where it belongs. There's a reason why on every PS system out there the reservoir is above the pump.

We got kind of screwed on our PS pump location. Other LS engines have them lower on the block but on ours it's the highest thing next to the alternator. I searched for suitable places and there's just too much **** crammed under our hoods that next to the brake fluid reservoir was the best place to put it and have it be high enough.
