Ask David and Farrar: Technical Questions and Advice About Carbureting a DeLorean

[AdmiralSenn]

Thank you very kindly, sir!

I'm not doing the engine thing yet, I've too many already apart in my shop and I like the engine in this one just fine!

Have you any thoughts on a smooth bore butter fly carb minimum diameter to make 180 horsepower, using IR and six throats?

Do you know if the stock runners will flow enough to make 180 horsepower?

I think they just might and I'd like to know the maximum they are able to flow, without being touched.


I noticed a plenum with runners cast integral on ebay that looks very much different than what came on mine.

Mine does not look like this. Do two styles exist? Could you point me to a picture of the other style if so and when where they changed?

Unless I'm missing something, that looks like a standard K-Jet (or EFI for some of us who don't have access to later PRV EFI engine parts) manifold.
