And is there anything else i need to make stronger for a huge shot or nitrous? They aren't welded and epoxied for strength. They are welded and epoxied to make room for the trenching that pierces THROUGH the cases with large stroker motors. Again...nothing to do with strength. The less welding you do to your cases, the better. Quote Link to comment Share on other sites More sharing options...
nitrious cub Posted January 18, 2010 Author Report Share Posted January 18, 2010 o ok yeah i knew they did that for trenching but i have seen a 4mill DM that had welding and epoxy? and 4mill is a small stroke. Quote Link to comment Share on other sites More sharing options...
J-Madd Posted January 18, 2010 Report Share Posted January 18, 2010 The case modification on the DM is because the cylinder bore is too big for stock cases; and the cylinder studs have to be relocated as well. No need to weld on yours. Just match the cases to your ports if you want, though I don't know how much that really helps on a Cub. Quote Link to comment Share on other sites More sharing options...

nitrious cub Posted January 20, 2010 Author Report Share Posted January 20, 2010 does anyone know how much HP a stock banshee case can handle? Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted January 20, 2010 Report Share Posted January 20, 2010 does anyone know how much HP a stock banshee case can handle? I've got 152hp coming out of stock cases on my 10mil twister in my sig. Make yourself a case-stay back to the frame on the stator side. Dajogejr gave me the idea on mine. Shoot him a PM and he can explain it to you in detail. Solid engine mounts are also a must if you're pushing bigger power. - Jared Quote Link to comment Share on other sites More sharing options...

dajogejr Posted January 21, 2010 Report Share Posted January 21, 2010 I hope you didn't buy a billet crank for it. I've seen more billet cranks break than forged... Since my cases are whacked to all hell, I had to make my engine stay bolt to the side cover (1/2 inch thick) This should not be TIGHT, it should move a little...

Aren't Crankworks and Twister cranks forged? Quote Link to comment Share on other sites More sharing options...
BigRed350x Posted January 21, 2010 Report Share Posted January 21, 2010 Daj, it almost looks like you have a stock petcock feeding those carbs. Good job hiding the pump. hehe Looks like your missing the rubber off your shifter. Quote Link to comment Share on other sites More sharing options...

And those front motor mounts are not stock right? Ann i am pretty sure my crank is not a billet its just a hot rods crank. Quote Link to comment Share on other sites More sharing options...
