I am going to lift the head off of our 225. Looks like the header is going to have to be used with the sheet aluminum intake. I am going to mount the header to our car for test fit before I ship it to Ron. I may make our header a little different. Also I am going to make the wastegate come out towards the back so it will be easier to run to the exhaust. The t4 should be good for 30 plus lbs of boost if anyone dare do that. This combination should be capable of putting down around 500 hp to the rear tires easily. Once we install ours it will be chassis dynoed to see what we can do. I am sure the engine will expire if the boost is ran to high but that is a chance we are willing to take with our car. We still have to half tub ours and install a cage before we are ready, so it will be few months.

Are you thinking about running a girdle or some billet caps on this? It seems the bottom end might become an issue. You must know this already, but I will say it anyway. Some engines under boost stay together just fine at high power levels as long as there is no detonation. A little whoops with the boost or fuel supply and the bottom end explodes. Aside from the damage it can really hurt someone. It is often blamed on the crank, since it gets broken, but is often the caps flexing or breaking first that lets the crank go. I suppose you would be on your own building these parts as well. I would just keep an eye on detonation.

I just got done looking at all the photos of the header. I guess I don't have anything to back up what I am going to ask you, but I will ask the question anyway.

The collector area looks wrong to me. It looks restrictive or maybe that better word to use is not smooth. It looks to me that the exhaust gasses are going to have to make a 90 degree turn to get into the turbo.

Is smooth exhaust flow as important in a turbo header as they are in a N/A header? Is my concern just?

I don't intend to put down your work, I am just looking at the pics and there is something that just doesn't look right to me.

We are going to do a lot of r/d work on this setup. Hopefully to have a decent priced turbo intake and exhust system that can be used on the street. Some of the componpnts i am going to use are 2.2 forged turbo pistons. We will put or race cylinder head on to start with it has been highly modified by Gary Bruner. Even though this head has been machined down 125 thousand of a inch I beleave with a deck that has not been machined but will take some off so it is nor straight and with 225 rods i can achive my compression ratio . Im shooting about 8 to 1. One thing about my home track usually on race day I can make as many passes I want. We want to use pump fuel and we have a pryometer in our car so we will be watching boost psi and exhust temp close. Maybe start about 6 lbs of boost and go up until we blow the 10 inch slicks off. Then we will do some stock clyinder head runs and see what happens. Im excited about this project and people are helping me on this but i still need advise so what are your thoughts. Thanks Ron Parker :D

Post subject:  detonation
Detonation is a real factor with a turbo. It is just like nitrous or a high compression engine. As long as the octane level and the timing is not advanced to high we should be alright. I have put levels as high as 700hp through foggers without hurting engines although they were not slant sixes but the principals are the same.

If you can give me some tips on how to build a smooth collector in such a small area I would appreciate it. How would you suggest I do it?

It was not my intention to cut you down, please don't be offended.
I was looking at pictures of turbo headers in a book at home. The race header I saw looked like a pile of noodles. I'm sure they had all of the tubes equal and tuned which I don't think we need to do.
The V8 turbo headers I have seen seem to mimick a upside down block-hugger header. Of course we don't have the option of having the turbo up high.
But in both cases there were never any sharp transitions. Maybe it doesn't matter??? Maybe it does, I was just hoping you would know.

Take another look and see what you think. I have revised the collector and it is a lot smoother. I also raised the turbo angle for a tighter clearance. I still need to intergrate the wastegate. Working with 304 stainless is a pain in the neck.

That is cool work James. we are going to buy the turbo next week. Also need some ideas about fresh air induction from the headlight opening and air filter ideas. All ideas will be welcome this is a user friendly project. Thanks Ron Parker :D

Yes we do, There is more then one slant, running with a high mount turbo. Here is mine.

It does look better, but I would not stress about it too much. I have seen really fast ls1 cars with nothing but and exhaust log feeding a single turbo. The expanding hot exhaust gasses are what drives a turbo, not the velocity of the exhaust.

I noticed your pic of the MT radial under the duster - that stance looks kill'r. I want to knock my valiant down a little to sit over my tires a little more I have 275/50 radials under it now and I think I could go to 295's without tubbing it (I already relocated my springs).

Post subject:  A Bodies
I must have had a dozen a bodies, some I have tubbed some half tubbed and some I have left alone. If you notice all the cars I build set low. As you know the old cars are not aerodynamic at all. As far as the header I know it does not mean a whole lot with the air turning 90 degrees when under pressure but I have the means to change it so I did. If you think about it the air has to turn like that entering and exiting the head. I want Ron's car to run at its best. As soon as I am done with his header and intake I will be starting on ours.

James, your son's Duster looks really cool. My first Mopar was a Duster from '72. The neat thing about them is the space you can get for bigger tires, and the better aerodynamics the
Duster offers over my current '69 Dart. Keep up the nice looking work. I hope to see it run some day.

Check out this video. It has the gray cuda and the blue nova in it. It is some of the racers from Louisville area plus it shows how much power you can get out of a turbo. The gray cuda was in December when the temp was about 30 degrees without any burnouts or vht to help traction. I have spent years working on getting cars to hook on the streets without adding weight. Watch the nova and the mustang. The nova leaves like it should and the mustang pulls a big wheelie wich is cool looking but not the fastest way down the track.
