7 second Buick T-Type build

[dsmawd350]

Rigid Race Cars has been doing work on a few local Grand Nationlas and T-types for several years now with much success. Both Dave Fiscus and Tony Gomes have Rigid Race Cars built turbo setups on their class leading TSO buicks. both have been 7.9x's @ over 170mph. We were recently contacted by another local buick racer who decided he was tired of other shops cracking, leaky turbo setups and wanted to run with the big dogs.



Bobby Don dropped his pristine Buick T-type at the shop with instructions to make him run with Dave and Tony. He wanted the same turbo setup and more!

when he dropped the car off it was sporting

T/A Aluminum Block
Stage II heads
precision pt-88 Turbo
Boost - 25 psi (more left)
precision Front Mount Intercooler
CPP Sheetmetal Intake
ATR / CPP Headers
CPP 4in Downpipe
Weldon Fuel Pump
400 trans w/4800 satll
and a 9 in Rear End

The car is getting a 321 stainless turbo kit starting with SPD CNC machined stainless flanges and 321 stainless collecters

the PT-88 is being tossed in place of a garrett GT47-88

the old mild steel 4'' dowmpipe and 4'' exhaust will be replaced by a 4.5'' to 4'' aluminum downpipe to a full 4'' aluminum exhaust

the precision intercooler and cast end tanks will be replaced with a garrett 28x13x5 bar and plate core with custom fabricated sheet metal end tanks as well as a completely redone aluminum cold side piping

we will also be making some modification to the sheet metal intake on the car in regards to the TB flange and its current mounting angle, to allow for more room for piping.

Here's the car as tear down began

The pile of old hotside and cold side parts, as well as the Pt-88. You can see the sheet metal intake there too. changes will be made to move the tb angle so its straight out and not angled down.

Got the turbo Mount all fabbed up. goes from the head to the turbo flange. Ill get some pics of it tommorrow. The 47-88 is all mocked up now and ready to start building around it. We also spent some time today cutting up and changing the intake manifold. Got it all done just needs some final welding.

The intake manifold is completely welded up and finished. ready for re-install.

We've decided to go ahead and get rid of all the stock type rubber coolant hoses and worm clamps on the car and replace them all with Aeroquip braided SS lines and black hose ends

Heres the radiator and water pump with the stock slip on outlets cut off and ready for the -16 male bungs to be welded on. all the bungs, lines and fittings will be here tomorrow from Summit.
