There is no way for you to make a "ram air" and keep the ac.. The condenser is in the way..

It looks like all three pulleys are right in line with each other. If that is the case the belt will only touch maybe an inch of the balancer pulley on the top and at the bottom. That won't be enough grip to spin the 2 acessories. Maybe i'm looking at it wrong or something though.
Since the LT1 uses a pigback style under drive pulley you can run a belt off of each of them. So there will be 2 really short belts.

Ah I see. That makes more sense. Each belt would wrap around the crank pulley quite a bit.

Bingo! I am also able to just run the alt. if I wanted as well by just taking off the power steering belt.

on the PCM issue, it would be ideal to use factory computers so we can keep all the tuning options open. like the 411pcm without the eficonnection cost.

More info on an oil pressure saver? I know it has something to do with the drive under the intake, but how does it work?

it will bolt on top of the oil pump drive, with the tabs to lock it in place. So if the composite drive breaks, the drive will not be able to pop out of engagement with the oil pump shaft. I will get a quote from the waterjet guy on monday, 12ga steel should work nicely.

I'm upgrading the stock PCMs to handle the additional RPM, it'll be an easy 5 minute swap

+1 on the roots blower, all the prototypes have fallen through. I think a drop in LS1 lid swap would sell as well. Maybe an affordable alternative intake besides a single plane connversion, something between stock and the miniram. I remember seeing a post about a TIPS 383 being tested with a stock ported LT1 and a Miniram and the Miniram made over 30 more at the crank, so roughly 25 or so more at the wheels. Im sure if a proven design could be made for $4-600 it would sell.

How about a ready to go, bare 8.8 housing w/ TQ arm mount. For those of us with no welder or fab skills. Make it ready to swap into the 4th gen, with all mounts. Just have the buyer purchase axles, carriers, gears, bearings, etc....and the buyer can have it assembled locally.

Let me know when the oil pressure saver and coolant crossover are ready.

more info and pics on this. I noticed the underdrive pulley being capable of being used when I did my alt. relocation. But what power steering pump/mount bracket/pulley? I'd really like to do an old school type of pump with it's own fluid container, instead of our remote fluid container.

I like this option. Then, you'd be able to run a SR engine, w/o having to run an aftermarket PCM..That would be enough, to make me switch my top end over, to a solid setup

Keep the good ideas coming!

Modified 7000+ RPM capable PCM, possibly with low-Z injector capability

AFFORDABLE 7500 RPM Capable Hydraulic Roller valvetrain package


Any suggestions, or things that you would like to see brought into the dying LTx aftermarket? Like previously mentioned, this isn't my road to early retirement, but I do enjoy R&D and seeing useful products come to life so lets hear it

*AN coolant crossover*
*over the radiator for T/A bumper*
Glad to see someone showing anitiative for the ltx scene...Been following ur threads since the day i seen ur car up close, in action...Keep us posted!!!!
