Just wondering if one was ever used in a street car.
Just wondering if one was ever used in a street car.
New Alfas.
I'm not sure what the question is?
If you mean a crankshaft that does not have split pins, then yes, oddfire Buick V6s (everything before 1977) did. They had a V8 firing frequency but they skipped two cylinders. (So basically, if you want to think like Chevy, the firing order would be like 1---4-3-6-5---2. Numbers pulled out of my hind end just to demonstrate the four - miss - two - miss order)
If you mean a V6 with even firing on each bank, that is practically every v6 ever made, with a few exceptions. Given that the natural vee angle of a V6 is 120 degrees, and practically nobody (except old Alfas) did that, even firing V6s have to have split pin cranks on 90 degree blocks, or cranks that look like short 4-main inline six cranks on 60 degree blocks.
Ford's Busch V6, incidentally, evolved to have a shared pin crankshaft like the oddfire Buick, but the throws weren't 90 degrees apart, they were evenly spaced. I'd like to say they wound up with a 150-90-150-90-150-90 firing interval, but don't quote me on that. (Edited because I did a math hiccup, numbers fixed)
I am thinking if they made one with the rod journals 180 deg from each other like the newish Ford v8.
In reply to dean1484 :
That wouldn't work for any six cylinder.
The thing with a flat plane V8 is that it makes the firing order even on each bank, instead of having a 180-90-180-270 firing interval (for example) that you cannot get away from with a crossplane crank. Unless you do something really screwy (like the oddfire Buicks), V6s all will naturally have an even firing order on each bank.
Flat plane V8s are somewhat literally two inline fours joined at the crank. "Regular" V8s are not, and this is where they get their distinctive rumbling exhaust - it's the uneven firing order on each side. And it causes all sorts of weird issues that people try to fix with crossover pipes, or X pipes, or bundle of snakes headers.
Porsche put the entire 6 in a flat plane. Subi makes a few too, but I’m not sure the crank design is the same as a new gt350.
In reply to AnthonyGS :
Porsches and Subarus aren't just flat, they're boxers. That mean's they're necessarily split-pin.
Yes, lots. Buuut, only if the V angle is between 15 and 0 deg.
