Big Block Twin Turbo 7.0L Cadillac video 1

Ive built a custom big block twin turbo 7.0L Cadillac, with a blow thru carbureted system, and twin intercoolers.
I installed two T3/T04B on upside down headers, with twin 38mm waste gates.
I have installed three RS Type BOVs and running the stock distributor with Proform 50k coil HEI ignition HOT upgrade, with 16 degrees initial and a check valve inline with the Vac advance. The Carb is a Holley 600cfm with mechanical secondaries, and nitrophyl floats. I set it up with a square delivery, and replaced the primaries with a Percys Adjust a Jet. I increased the PV restrictions by 135% area.
On the tail Ive got twin OBDII Catalytic with Bosch single wire O2 sensors.
The build is a 1935 Chevrolet.

I apologize for not posting any more Videos, It's hard to get a video, when your' driving your beast around town. I'll have someone take one soon, so I can post, it's getting close to complete...

where in oregon are you?

If youre nearby id like to see this.

And no your 10 bolt wil not hold up to that kind of power!

@psychotikpaisano Friend, I can't post my location on the web... Too many looki lues already... I'll be at the Portland Roadster show in March, I just hope I've got all the body work done by then!!

the turbos r really small

[twinturboengineer]

@HSVboy2c Thanks man, but the new Hybrid turbos spool faster, and produce more boost... 25psi!!!! these bad boys spool as fast as the engine revs!!!!!!! that's INSTANT BOOST

A GM 10 bolt could'nt handle the torque of a Honda motor

thats so cool hahaha. love the end part of the vid :D

[twinturboengineer]

@christiondavid Dude they are RIGHT... What happened was the fuel was slapping the back of the bowl, and pushing through the opening at the top of the carb, see there's a slosh vent, on the primary you've got to remove, when you install the second metering block, so there's no slosh protection... you know what happens with the fuel, when you rop in the Big Cad, TORQUE the fuel was spewin right over the tower!!!

@twinturboengineer i have a question on the percys Adjust-A-Jet, over at the mustang turbo forums website people have asked abought useing the Adjust-A-Jet and they say they dont use them because they leak under boost just wondering if you noticed that with your setup ????

Dude the 10 bolt works great!

This thing is a screemer!!!

I see you've got a twin turbo too...

The engine fan pulls air based on rpm through the radiator, with the area of the intercoolers this is ideal, because thehigher the rev, the more heat transfer.

I've driven all over Portland Oregon, doesn't over heat.

I'm running twin waste gates, because the turbos will over produce without.

This thing spools instantly! I used the smaller turbos, to get the instant boost!

At 5000 rpm Boost is 12
