Default Can we start a FI LT1 specific thread?

There is SO much good information on here, its overwhelming! But i have an LT1 and it really gets to be a hassle trying to sort through everything and figure out WHAT can be used on an LT1. So i was thinking, with all this wealth of knowledge, can we all work together and make a thread for LT1 owners to use as reference? I would REALLY appreciate a truck manifold walk through. But anything DIY or homebuilt etc. If you paid to have your turbo done, post it up as long as you have pics and can walk us through it. But the goal here is to have reply after reply of LT1 turbo builds. Please only reply if you can walk us through, step by step, your build. If you have an LSx car, i dont mind you posting up as long as you can explain what to do to adaot it to an LTX car. So please guys! Lets get it going!

Here is an LT1 build we just recently completed, using a ProCharger F-1A. A lot of what we did on this car would also work with a turbo. Bob

I agree. It would be very beneficial for the LT1 specific FI enthusiast to have such a knowledge base, parsed to have only what is LT1 related.
I have a lot of my build up in my sig's link. Pictures, dimensions, sources, hassles, setbacks, triumphs. I'd be glad to contribute.

On my link, you really need to go to the link, then go to the bottom of the page and work your way up to the top. The bottom links have the pictures, part numbers(where applicable) and then the installation related topics.

Sorry, I meant beating the unbeatable Lsx. Not Tiago power, lol...
1000rwhp? I barely can get what I've got to the ground and not tearing up hard parts. No need for the Max for my street car. Just enough to beat the other street cars.

never been on a dyno, but i've been running 24psi through a GT4788 LT1 383 for about a year pushing approx. 1200hp worth of fuel through it (95lb injectors at 87%) i think it's ultimately all in the tune.
