Hey torquie, what do you think about using the Roe blower on a stroker motor? For some reason I have a vague recollection that you held forth on that issue once a while back, but I may be wrong. Either way, I'd like to hear it again.
I like strokers to a point - and adding boost to them seems a good idea - except you need to be mindful of the maths and basic block capabilities under the extra stress of boost. As a rule of thumb as you go up in stroke you should go down in rpm - you can build around that for racing, but for durable street engines - once you go under 1.5 rod stroke ratio you're asking a lot to spin that baby much past 5500rpm - the piston speed on such a short rod ratio is huge!!!
Remember that boost is like adding more engine cc - so there is a valid argument - why stroke and boost - just build a really strong stock sized motor with good rod stroke ratio then add more boost to get more torque. That way you can still safely rpm and hold it.
There's a lot of argument over rod stroke ratios etc - at end of the day - a good ratio helps an engine to be reliable at wide open throttle and enjoys good bore life and good rpm potential. A poor ratio is ok for low end but has to be very strong to take high rpm and puts a lot of side pressure against the bores.
what have i said? not sure
My opinion is this: I'd rather build a strong motor and boost it than stroke and boost it.
I'll guarantee you I can make more power reliably from 488 or 500 cubes on boost than on 550 plus boost - the block will let go at 550 long before it will at 500 - anyone who doesn't agree doesn't understand engine maths. The rod stroke ratio at 550 cube is good for a tractor but not a 6000rpm long life street/track engine. When someone builds a 1500hp 550 V10 that can stand WOT for more than a few seconds - I'll change my mind - but the stress will be huge.
BUT - If you reduce redline to 5500 or 5800rpm max - a big stroker will sound good on the car resume and will make more torque/power at any given boost level - so you could make more power on less boost.
It could be built stronger than stock as a stroker should have a stronger crank than stock, and should have better rods and pistons - but if you spin a 543 cube V10 to 6000rpm and stay there - eventually you will be asking for trouble IMHO.
So it comes down to what you want. If you limit the rpms - the stroker will make more power. But you use a Roe SC - known for its bottom end - so why add a stroker? Why not add better rods, pistons, heads and cam - and make the hp and safely rpm to 6000? Which one rocks your boat?
