New Twin Turbo Big Block Buick Build

my goal is to drive in on an ET Street Radial, drop the air pressure, run an 8 in the quarter and drive back home. I know the block will probably split in two, but there are too many parts still needed for the TA block and I want to see if that thing lives before I plunk down 6k.

 

Is it at least girdled and filled?

nope. I am just going to roll the dice on this baby.

 

Maybe you should at least put a diaper on it...if it splits in half at the track, the oil will ruin the day for every racer in that lane afterwards.

Awesome project and looking forward to updates.

Cool beans. Glad to see you still have the bug and are building some more new and cool stuff. Are you avoiding EFI on-purpose?

 

I have so much money wrapped up in this thing I just want to get it on the road. I am probably going to have 50k in this thing before paint, body and interior. Probably a FAST XFI when I can afford it.

 

Real nice setup your building there and I can understand the cost issue we wound up spending almost 45k on just the engine for our custom car. Its a Twin turbo T66s, they make some big steam!! Made 700hp with only like 9psi boost level and non intercooled. WIth a SBC

 

Did you see the setup that was for sale on here? A GREAT deal if Chris still has it. It was Kerry's, who passed-away; Kerry had plans for a similar engine combo to yours. I can't remember if it was for TE or SE heads.

 

More pics coming soon

 

Great build! I wish I had those heads, they leave WAY more room for the plumbing than the regular style heads. Well, that and they certainly flow better. No love for the 350's though.

 

I am more than satisfied at this point. manifolds going to machine shop to clean up flange and then the piping for the twin intercoolers will begin. Parachute probably going on this weekend as well. Wilwoods for the front coming next week and those are going on as well. Car should be done in 2 to 3 weeks and engine going to builder. Tranny be here next week as well. Car should be at track this year. Hoping for 5s in the 1/8 on radials.

 

dont paint it David itd be sweet without being painted.

 

Yeah, with the suspension it has, it should hook really hard on a narrow radial. Should be able to squirt off some sub-1.4 60' times. What size are your primary logs? Also, never heard on the wastagate outlet plans. Dumping the WG's or piping back to the DP's? Looks tough on the driver's side to tie back into the DP.

Kick ass project! Just a tip on the manifolds, stainless turbo headers tend to crack right where the pipes meet the flange at the head. If you weld a small triangular gusset from the flange to the top of each primary pipe, about 3/4" away from the flange, it makes a big improvement in strength at the flange, and could save you some headaches. Stainless doesn't tolerate the weight of the turbos and DP's with heat cycling so well.

Love the dice rolling approach. My style totally. My stock cast bottom end is still kicking after a $150 PAW rebuild kit and 10psi, 87 pump gas, no intercooler with 34* timing!

 

Will be tied back into the downpipe in terms of the wastegates. I don't plan on revving it too high so I hope this thing holds together halfway decent.
