Twin Turbo, Super Charged, Nitroused, '69 Camaro

[The Violator]

2 turbos and a supercharger and only 14lbs of boost? Maybe that's because the turbos are plumbed into the back of the scoop, that opens in the front so all the boost from the turbos is just blowing out the front.

QFT"thumbsup"



The turbos do absolutely nothing but look interesting and maybe make some noise as they blow air out of the front of the bug catcher. I would venture to say if the actually spooled up they might even rob the engine of power because of the vacuum they would create by blowing air across the opening of the carbs and out the front.

That's an abortion for sure in the engine compartment.... Only car I have ever seen and heard run good with twin turbos and dual superchargers was rick dobbertin pontiac j2000 but that's a whole nother topic..

It looks to me like the scoop is just mounted on top of the pressurized plenum, the scoop and the turbo inlet piping is to add to the obnoxious factor.

Understandable, but how does it work with the turbos blowing into a scoop that is open to atmosphere?

Yes I didn't watch enough of the video to post my first statement. I posted how dual charging should work...as you mention this guy seems to have missed his mark. Unless he's modified that plate under the scoop no the carbs to do something magical to shut off atmopshere from the scoops. He doesn't appear that smart.

That would be hilarious and quite possible.

The turbo intake and the output are both plumbed into the scoop above the carbs. There is no way that they are doing anything but recirculating air.
The 14psi of boost comes from the blower and that's it.
The 200hp shot of nitrous does little more than cool the intake charge. Nothing wrong with that but it'd be smarter to inject it after the blower when the air is hot, not before.

Even the plumbing looks like it was done by someone who knows nothing about turbos with all it's 90 degree bends.

Show cars, ugh. :roll:


"Listen haters, we all wish we had a car like this." :lmao:
Only so I could sell it.

I'm guessing the scoop is just there for the inlet and the box under it (above the carbs) is sealed from the scoop for positive pressure.

Like Tommy said, what a waste of a car. :roll:



... Look at me! Look at me!

Ah, I can see that now, good eye Dean. "thumbsup"
Still looks to not be a very well designed system as far as flow goes.

Drugs are bad mmmmmkay......

Done when idiots can't think how to size turbos to eliminate this claimed lag issue.

Make 500whp on a sub 2 liter engine and have 50% of the rpm band be above 400whp.

Make 1500 on a sub 6 liter engine..., etc. There comes a point in the quest for power where you will have unavoidable lag.

Superchargers win on all accounts. Turbos are just cheap and easy.

That's a matter of opinion...A turbo will usually make more power. And not sure where you are getting a "cheap and easy" turbo set up but if you have some connections let me know lol. A big single turbo (88mm or so) is going to have some lag, but when it lights, hang the fack on. Twin 67's will make you whatever kind of power you want, and light almost instantly. This is based on the ls engines, I can't really speak for any other motor.

Compared to a twin screw blower, a turbo is kind of old hat**, though the blowers themselves are expensive and mounting is difficult. To me it seems more involved than bolting on a turbo and an exhaust manifold. 500whp on a 2 liter will take a turbo that can flow ~50lb/min and those hunkers don't spool up very well on a 4 cylinder. When I consider street use, traction, power needs, vehicle weight, and tire size I can't make sense of a turbo on a 4 cylinder. Sure you can make 300whp with a fast* spooling turbo, but who doesn't want 400!? What's the point of a spending a thousands of dollars on an economy import if a camaro with a cam and a chip is faster.

I can't really make a strong argument against a those aluminum chevy small blocks, so I take that back. ha. Who would want more than 500whp anyway?

*Still doesn't make the power down low a good blower will.
**Even oversized roots blowers outperform turbo's on 4 cylinders. You can make assloads of power down low with em, but there aren't many kits you can buy with such large blowers. You have to engineer and build it all, which is above and beyond my skill set.

Who cares if it doesnt spool until 4k? Its not gonig to matter if you are in the proper gear anyways. If you have enough traction to take full power on launch you can install a stutter box to build boost before launch.

They both have their place and it depends on the needs of the owner. If you DD you car, a turbo makes sense in my mind because you are not boosting if you are not getting on the skinny pedal and that makes for better MPG.

You are right about the new generation small blocks making serious power with a few upgrades. I have a cam, intake, and exhaust only LS1 that puts down right around 400 wheel, its hard to argue with that. The problem with that car in CA is that it is completely illegal and impossible for me to smog. With the amount of time it takes to swap everything out I have just been letting the car sit because I dont have the time to rip the motor apart and swap in the stock parts.

Now what I am thinking of buying is a WRX, my buddy has one and we did an STI turbo and intercooler install the other weekend in about 4 hours. He told me that there are stock location turbos that will easily make 400 wheel without any trouble. Now, if your smog tech is an idiot you could just swap back for the stock intercooler and get your smog since it is AWD it doesnt go on the dyno so there is no "road test" done so there will be no boost and it wont throw out any extra pollution. Even if you want to go back to stock it is only an afternoon job.


If I had the money to build anything it would be an old muscle car with a twin turbo LSX in it. That would be fun!
