I just mocked up a SB and BB in my F body Aspen. SB is no problem since they came from the factory that way. I've got a bare block w/bare heads sitting there jacked up from the bottom. Looking at all the space issues. This car will be a street/strip car with emphasis on street. Bolted on the passenger side a reversed factory exhaust manifold and a trashed turbo housing to show much room I don't have. I know it can be done but I hate all the disassembly that would take place to service just about anything in the engine bay. Can I run the turbo just off the passenger side of the motor and the drivers side run off a header straight to the exhaust? If a 4 cylinder can make a lot of HP from 200 cubic inches, can that work the same with a one sided turbo'd 440? Putting out some low end torque N/A with the other bank spooling up.

I have no idea, but I sure it can be done, biggest issue i would think would be a split cam timing (custom) for L &R right banks, since exhaust back pressure/scavenge would be vastly different, and not sure how firing order would add crank longevity the different power pulsations. bump


Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

No, the fueling and timing requirements are going to be substantially different between the two sides of the engine. it would be impossible to tune effectively.

I have to admit that I did try this. First time trying a turbo. I built one header that fed an old mack truck turbo. No wastegate. It would make about 1 lb of boost, and would overheat the intake like mad! I had an old CH4B intake with the exhaust cross over still opened up. That path through the intake was acting like a wastegate. After figuring this out, I put a valley pan with the heat cross over blocked. That got me to a max of 3psi boost. I finally plumbed the exhaust on the other side into the turbo. Ended up making 9 psi boost with no wastegate. Very poorly matched turbo for the application.

Why can't you flip a set of exhaust manifolds or shorty headers, custom fab a crossover pipe and put a turbo flange somewhere towards the center in front of the engine.

A/C might be needed and as I had stated, how much stuff would need to be removed to get to the basic maintenance as a daily driver. When I look at all the s*#t that has to be removed to service my crown vic interceptor...well I just give up and drop it off for service. This is not the way I like to do things. All the race cars that I had were built on the premise of easy maintenance. Burning hands/arms ans busted knuckles are what I did in the old days. Not anymore.

What exactly do you expect to remove for "daily driver maintenance"?

I can change plugs on mine right after a run no problem. Valve covers come off easy, and I've even had the head off it without removing the turbo.

All that said this is with a pretty big turbo, there are lots of smaller options them what I have.

If you take your time, you can make it all fit pretty easy.

Manifolds don't HAVE to be flipped. Just run the second pipe where it needs to go.

The turbo from half the cylinders has been done for sale to the general public, by Volvo. They called it "light pressure" turbocharging.

It was on a transverse 6, they used 3 cylinders to drive the turbo and got single digit boost which was all they wanted.

Of course it was fuel injected.

For a carb I'd suggest using a blow through system feeding all cylinders. Cam the engine to maximize the turbo output.

Compressing the air does raise its temperature, it's called adiabatic heat of compression.

Problem with doing this is that it will make backpressure to drive the turbo. This backpressure will effect cylinder fill on that bank of cylinders. I would think this would be a tuning nightmare.

If I could type with any kind of speed I could keep you entertained for hours! The area I'm most successful in is failure.

LOL... I love the fact that you actually tried that. It's like trying to feed a big block, with the exhaust volume of a 4 cylinder... just doesn't work too good...

You two are definitely pioneer's of the mopar turbo stuff... so glad that you both share your knowledge and failures!

You should write a book, Trendz. I really appreciate you sharing your experiences!!!

haha me too !!! i have often told my wife i should write a book about the things i have done that were a flop. laugh2 the sad thing is, i still accomplish failures almost weekly, if not more often ! it seems the older i get the dumber i realize i am..... biggrin

I don't think it'd be that difficult. Cam for the turbo. Use a decently high compression ratio. Yes, the different cylinders will fill differently, but they both take the same air/fuel ratio.

Back in my youth my cousins introduced me to a dirt track racer named Vern. He wasn't rich and it hurt when he broke his motor. No money for a different one. So he put together a motor out of what pieces he had lying around and in the end there were three different compression ratio pistons in the engine. I think the cylinder heads were different as well. We went to see his first race and he was competitive. He finished mid-pack, where he normally ran. It taught me a lesson. Engines are, in the end, an assembly of greasy metal parts. They aren't nearly as complicated as we make out.

Another unseen lesson their may have been that to go fast you need good parts put together properly and you need a good chassis to win in oval track racing, correct? work
I use to help a roundy round racer that would normally qualify really well and then proceed to race his way to the back of the pack in a very short time during the race work
His brother was the opposite, he could, and did, advance his position during the race work My message is it ain't just the car or driver, it is the total combination shruggy
