Anyone kno anything about supersixmotorsports.com and their stoker motors are they real and is it worth the money
Your pricing is off for some reason. Their prices are listed on their website and heads should be about a grand.I'm also interested in his 4.3 long rod stroker. I called and talked to him a couple of times about my application in an SC, and he seemed very knowledgable and familiar with our cars. Since I will not be out to be the fastest SC on the planet, I think his engine would be great with say, an MPX, or an AR. I asked Tom about theeir new block ("99-2004), whether it was compatible with the SC peripherals (AC/accessories, power steering, etc) and he says it is. Overall I think it'll make a great package. My car has 187k on iit right now, and when it hits about 210-220k, I hope to have the bucks to buy his 4.3. One thing about the pricce bothered me though. You can buy the short block for $3500 and the long block is $7300, so that means his heads are $3800, kind of high, is it not for the heads?
'95 SC auto, 187k, still strong, APTEN chip, 76/75mm TB/MAF, 5% pulley, SCP exhaust w/Kooks coated shorties.
The main problem with a nodular iron crank is strenght. They are a good peice however they cannot withstand the extra forces the SC setup produces. I'll put it in layman terms best I can.
Consider the SC crank pulley as an extension of the crank. Then think of where the crank is attatched (frontmost main bearing cap). Then think of the belt attached at the outermost set of ribs...
Consider a N/A 3.8 setup with a centrifigal where there is no second set of ribs and the SC runs off the same set as does the rest of the accesories.
At 5,000 RPM's there is allot going on where the belt meets the crank pulley. The further away from that main bearing cap the stronger the material of the crank needs to be so it can withstand certain loads and forces occuring at that location. The closer to that main cap the forces are occuring the less strenght needed to withstand them.
Thats why the SC came with a steel crank as oppossed to a nodular iron one..The extra strenght was needed due to placement of that outer belt..
Sure there are many other factors on why youde want ro need a steel crank in certain applications however power was the least of the many reasons a steel crank was used in that application.
You can use a nodular iron crank however your engines life expectancty will be greatly reduced
No, this is not why the SC needed a stronger crank. It needed a stronger crank because of the torque produced by the engine (thanks to the supercharger). Not because it needed more strength to drive the supercharger.

Lets say I have alot of experience with nodular iron cranks and the stresses roots type blower setups put on the snout because of the design of the system. I know this because when I was a poor college student it was cheaper to use factory shortblocks then buy aftermarket. Making close to equal power my stock shortblock held up wonderfully with nitrous and not so wonderfully with my B&M roots blower.
It had nothing to do with detonation although detonation will surely leed to a sooner failure. Never threw a rod or spun a bearing causing a crank failure. I have however twisted nodular iron cranks and not just one...
Not only does the pulley itself from weight alone cause extra stress but where the weight is..Further away from the crank...Then add the stress of the tension on the serpentine belt further away ...Its cumulative...
A perfect tune will not make up for inadequate engineering strenght of parts. Believe me Ford would never have spent the extras $$$ on a steel crank unless they had to. But you can always run an iron crank if ya like..Make some good power and prove me wrong.
The stress put on the crank by the pulley/belt is negligible.
Not that I'm an engineer or anything
