I have little etch marks in the case that nobody knows about!

 

Wow, I didnt think the motor was making that much power. I was thinking more in the 350 range. I knew there was a reason the car felt faster than my 996 TT.

 

What exhaust system, intercooler, and turbo are you using on that?

 

Would you mind emailing that to me?

930turbo@mindspring.com

Thank you

 

Joe can you email me your excel file. TIA

 

Not everything you requested but will be of interest to all.

The exhaust is factory stock 89 930, intercooler is a fullbay Powerhaus unit and the turbo is a standard K27.

 

the 3.0 is a great starting point...I really need to get mine dyno'd if your's is putting down those numbers. I'm assuming your running it at 1 bar or less?

 

1 bar according to the tach boost gauge.

I think your right about the 3.0. I was told that 10 years ago by a guy that built an identical car to mine. However, he had EFI'd using the Factory Motronic from a Carerra. I remember the ride in the car........it was so damn fast I couldnt believe it. I had an 89 at the time with CIS, similar mods and a G50 from a Carerra and it didnt quite accelerate like the 77 3.0 did. Also, when I look back at the IMSA 935's that used 3.0 motors they were making as much power as the 3.2 and 3.3 motors as well.

 

Joe, if it isn't too much trouble can you email me your excel file too? I'd like to compare it to what I calculated for my SCCA SPec Racer Ford. TIA, Jim Parker

isnt that a record for CIS esp with a 3.0 litre engine? Seems mad! What about the a/f ratios at the time?

 

Joe, is it possible to send me a copy of your Excel sheet as well?
TIA...

 

Heya Stephen,

What does the car have on it to get those numbers. That's already impressive for CIS on a 3.0. Also, the stupid morons that "rebuilt" the motor before I on my 79 motor decided to use a a 3.0 intake manifold. Why I don't know? I then suspected the motor wasn't a 3.3 and a 3.0 instead. I'm pretty dead cert it's a 3.3L because of the case and we measured the stroke and it checked out too. I'm not complaining since I bought the car for so cheap and the body is impecable. However I wasn't too amused when I went to install the Kokeln IC on there and um.. heh.. let's say that didn't work too well now did it. I found a 3.3L for 400 bucks with the TB and other stuff so I'll use that. Sigh... Either way if a 3.0 can be made to do that with just some bolt ons- that's impressive. EFI will nuke some of that lag tho eh

 

You have to pay attention to the details. Head work is a big bonus here. This is where you can pick up free HP. Also the cams that you use. All the little things add up. It is like when we add 3.4s Ps and Cs. It doesn't add much, but overall it adds TQ down low and a broader band.

Yes, the TB of the 3.0 is at a different angle then the 3.3

 

Hey Alex......the 3.0 liter is my car......Chet here in California with the black 996TT. I didnt know you had a 930 turbo. Call me if you still have my number. Did you ever pick up the stock 996TT suspension parts from my car over in Campbell?
The angle difference I remember measuring when I built the motor originally was about 11 degrees tilted toward the flywheel direction. I think that it may also contribute to a better transition of the incoming air into the manifold below the throttle body where the air has to make a 90 degree turn toward the cylinder banks. I could be wrong but that is the reason I elected to keep the 3.0 manifold and have the neck modified on my intercooler instead.
