Hrm, belt driven turbo + carb draw through setup + TR7. I'm no mathemetician but Fail + Fail + Fail = Imaginary Fail?

looks more like a supercharged TR8

That's what I was thinking, I've never seen a belt driven turbo like that...

Dealer selling car. "Victory Park and Sell".
No clue what they are selling. It is belt driven blower.
The dealer knows about cup holders and CD players.

Looks like fun to me.
Also- that is clearly an example of quantum fail-sics. Eventually, if you fail hard enough, it comes back around the other side to awesome. I believe this vehicle has.

Also known as a centrifugal type Supercharger.
Vortech is a popular brand - see the bottom right of this pic...
Less plumbing thatn a Turbo, easier packaging than a Roots or screw type. These are most at home on larger displacement engines. Smaller engines will suffer from the parasitic losses of a supercharger at lower RPMs. A V8 however is a great place for one.

Thats a really old B&M supercharger kit (procharger?) that was designed to be used on Corvettes with limited under hood clearance. Its a roots-type blower NOT a cetrifugal type. BTW thats a SBC not a Rover V8 in there.

with a Vortec yes... but try a Rotrex, you'll be surprised

That does appear to be a rootes type blower. But I bet that it has a turbo boost gauge inn the cockpit.

I want to, but they don't have a kit for the 94-97s yet. How do you like it?

Agreed, it was popular in the 90s: B&M forced induction supercharger drawing through dual weber carbs. Roots type blower. If it's been setup right, the throttle response should be REALLY fast. usually they were set up for 5-12 pounds of boost. Nice sound, too. Nice sleeper look to the car: no TR8 badges all over the car. If the shocks and springs have been upgraded (the OE were too soft), it should be a blast to drive. .

1976 Triumph TR-7 V-8 Turbo WoW 5 spd trans 11 second car
Is 11 seconds how long it'll take to scatter the rear end all over the ground?

I don't believe they made the TR-8 in '76, so it is a swapped TR-7. I think the few they brought in as test vehicles were all '78's, and they didn't really go on sale in numbers until 1980.

Roots types are also known as screw type, and are positive displacement - the screw pushed the air into the engine. The Centrifugal types are like the fresh air side of a turbo, they spin the air at high speed against a curved wall which slings it into the engine due to its higher velocity from the centrifugal action of the curved surfaces. Here is a pretty good animation describing the 2 types.

That looks like a old 142 blower kit, man those things are great and they can use standard carb's.
You can fit a really really big carb one of those things, I had a 1050cfm on the cobra with the 72.

Not really. Perhaps you're mistaking a screw type for a twisted lobe roots like an Eaton.

This much discussion and incorrect info over what is a roots, centrifugal, twin screw, or turbo seems.. like it shouldnt be necessary here??
To all who dont know it yet, take a few minutes, learn it, and you're done.

man picky picky on terminology, fine, a belt driven turbo is in fact a belt driven centrifugal supercharger vs a roots, or screw type, a turbo is exhaust driven with a turbine, now is everyone happy?

That turbo looks more like a supercharger than any other belt driven turbo I have ever seen! LOL

Don't have one, but I've been following the Rotrex for about 4+ years now... the big advantage it has over a Vortec type is the Rotrex uses a planetary drive system, which mutiplies the forces quicker then a typical Vortec does

If we were really picky, we'd call the exhaust driven rigs "turbosuperchargers".
Then we'd discuss intercoolers vs aftercoolers.

Yeah but what about turboboosters and expensive torques?

In reply to Raze:
That's what I was going to say....I think we can just call it a torquobooster and call it a day.
