Helping a member on his V-12 Jag project that will have Twin Turbos and a Doug Nash 5 speed (might be a Richmond 6 speed) in his special body XKE Jaguar.
This guy is a FABRICATOR. AMAZING WORKMANSHIP! Boost system will be the easiest part of the whole deal he has been working on.
Has his Pontiacs but this is a special toy with boost. Assuming +1000 HP for the V-12. Believe it is a 6 liter engine (366 cid or so).

Redoing mine but it's purely street. Nothing like some of these guys. More of a freshen up but changing quite a few things I knew were wrong from day one.. I have another project I just picked up but it doesn't have its place here unless anyone's interested in an 88 RX7 LS single turbo swap?

Not exciting, but changing my oil.

changed my rear cover today: Saved the Redline Shockproof because it looks new ( probably re-use it in the 95 Lincoln Towncar).

Brought my 10' manometer home from work, need to hinge it at the 6' level for practicality.

Maybe get back on the on-demand boost. It'sa 2- Stage jobby, jusy above hobo level.

My 79 Trans AM with EFI and a turbo has been sitting a few years now, got side tracked putting LS engines in two mustangs I have. I have too many projects and need to slim the heard.

Anyone interested in a PHS documented 1976 Black on black 455 4sp car with a rear console? I may sell that one to fund the other projects LOL.

Research and nothing else. I’d like to build a single setup, but I’m too afraid of windowing a perfectly good block that has near stock internals.

Trying to work out if I have the energy to build a set of manifolds to run a BW S475 T6 1.01 on my 400.... ATM it's a quite healthy street car at 11.7 @ 115 @ 3700lb, so i'm torn to pull it apart as I can drive it anywhere as it is now but boost is the worst drug on the market today.

I have taken a break from my 74 after hurting it at Norwalk. Apparently 25 psi was more than what the stock mains wanted.

But I have been playing with my lemans wagon with the gt45 turbo and bone stock 350. At Norwalk I ran a best of 15.3 with it on 7psi. Since then I added meth injection and turned boost up to 14 psi. First outing with the boost up it went a 14.2 but it wouldn't rev over 4k rpm. So I threw newer stiffer valve springs in it and that seemed to fix that issue, next time out it went 13.5. It was missing out a little at high rpm. So I updated the stock hei with a 6al box and a hotter coil, along with building a 2 step to launch on more boost. That seems to have fixed the miss and I can launch on boost now. But weather has not permitted me to go back to the track. I also put in an exhaust cutout to test the difference between super quiet turbo muffler and open exhaust. Hoping for a 12 my next outting if weather holds! Junk stock engines you don't care about are a blast to beat on. I have a good running spare 350 for when this one kicks the bucket I got for free!

Swapping from Blow-Thru to FAST EFI. I get to start the tuning process all over again.

Also trying to fix all the little things that broke this year that I just put a "band-aid" on. Its amazing how many little things need minor attention after a year of beating on this thing.
