I am new to this site and it is great. I searched for some info on a pair fo turbos for my 427 sbc, but I am not sure if I am in the ballpark. This is what I am looking at:

I'm not eager to whip out my calculator and do the math here for you, since i'm not experienced enough doing that to be very confident in my results, lest I steer you wrong.

But first, some info on the motor eh?

What's the SCR on that 427? I figured it'd be impossible to get a large cube small block like that to have low enough CR to make a turbo setup worthwhile? Or will it be burning race gas?

What HP, and what RPM do you plan on spinning it to?
Pure race, or street car or...?

What camshaft are you going to be using?
Cylinder heads? Flow data?

It will be a World Block, Winberg 4.00" crank, Oliver 6" rods, Motown 23 degree/ 235cc runner/72cc chamber heads, around 9:1 comp., and E85 fuel. I am just starting the plan for the build, I have the crank and rods, and alot of research to do. I have read the turbo bible and am trying to size turbos, but I thought you guys may have some insight and like to see the build. I did not find any info on turbo setups running E85 fuel. The car will be a "street car" and will turn around 6500 RPM, and I would like around 850-950HP. I hope someone else with more turbo knowledge then me has taken advantage of this new fuel.
Thank You,
Vince

Oh, I think you'll be a ways over that power level, that's for sure.

I think you're going to have a hard time finding pistons to get down to 9:1 CR. But I wish you luck, if you find some, let me know.

You can go pretty wild on the cam there too, that's going to be flat out nuts.

Sorry, I can't help you, but hopefully someone can. Good luck!

Go with TWIN T76 and you will have room to grow if your 8-950HP goal isnt enough once you get use to it.

I think 900HP will get me in enough trouble. I would like to hear from others that have played with E85, it looks like it would love to be put under psi. Thank you for your time and I will keep you posted on the progress, may be slow as I do not like to outsource anything. This is the car it will go into.

let me find you a link over on the turbomustang site where there was/is a guy runnin E85 and boost. TONS of good reading over there also.

The description for the turbos is a direct copy of a chinese turbo AD. The engine sounds like a good durable build. It is up to you, but I would not install cheap chinese turbos on that engine. I would have no problem with them on a much lesser engine.

The turbo bible is good. Go to www.turbobygarrett.com and read the three tech articles. They will show you how to pick out a compressor. Then go to the turbos and look at what is available for turbine A/Rs. Compare your engine combo to what others at turbomustangs.com are running.

In the end, you will have a GT/HX series comp. wheel minor of 70mm to 76mm. Or a couple of GT2X, GT3X, or T04 compressors if you install two turbos. That is assuming 700 - 1000 FWHP. For a "street/race" setup you will probably end up with a 76mm or bigger inducer wheel.

My projects take for ever too. It takes a long time when you try and make everything yourself. I like that firewall. Is that alumimum? 5052 or 6061? Are you going to make your own inner wheel wells? I noticed the fenders are lightened.

EIDT: E85 is good if you can get it. Out here in the sticks it is only available 2 states away. Since you are carbed then it is about jetting. EFI needs bigger injectors....much bigger = $$$. You could also spray it with a water/alky mix. Bias toward being heavy on the alky side. My plan is to eventually try to run 87 octane with water/alky pumping under boost. It will be a learning experience and I may lose an engine or two on the way.

The firewall is all steel, as is the compleate floor and rear tubs. I built the MII front back in 1991 when I was 18yo, I think I should have tried to sell them! The fenders are stock, and I will make alum. inners when I get the turbos on. I built a truck-arm rear suspension and mini tubed it so I could keep the rear seat so we can get the groceries home . Here are some pics of what I have so far, I think every 10 sec car needs a cup holder.

Uuhhuuu! and A/C :0


Nice work BTW

You would probably have to use shorter rods.

vinnysnova

I think I may play with the cheep turbos first on my 355 in a 62 nova. That way if I smoke it I won't be out $7000 in broken parts . This engine is just a steel crank copy of the ZZ4 crate. I am upgrading the rods to scat capscrew 5.7's and Forged Speed Pro dish pistons. It has been a great daily driver so far and it will give me a chance to learn the tune on the TT setup.
This is the test mule, it has had alot of combos in it:
