Hey Dudes,
Since I have a growing interest in 928 hot-roding I have been wondering why it is that people only discuss turbo vs S.C and never forced induction vs stroker? I understand they are apples and oranges but they are two different roads to the same destination are they not? I see plenty of 'selling points' to supercharging a 928 (comparably inexpensive, completely reversible, better fuel economy(?), ready made kits, etc.) but I don't see a similar list when discussing stroking a 928 engine. Is this because people who want to stroke (snicker) simply have more of an interest and the skills needed to mod the engine, or do strokers ultimately give you the most H.P./T.Q. that is possible for this car, and price, ease of installation etc. are not factors that are important? If you supercharged a stroker would it send you directly back to 1955? I'd like to hear all opinions.
Thanks!

Hold on a second, let me get comfortable.

 

I think the reason that it isn't discussed more often is because the costs are so different. The forced induction option has been pretty thouroghly worked out and can be installed by any decent automotive mechanic or mechanicaly inclined owner. The stroker requires much more money and know how to pull off succesfully. I would love to have a stroker but it just isn't even a remote posibility for me. An S/C or turbo system is within my grasp.

Thats my two cents worth.

 

The idea that you can simply bolt on a kit over a weekend and make big power is seductive. Signing up for an engine rebuild is NOT. Adding in the additional costs for all the special bits to stroke it while rebuilding makes it rather expensive and time consuming.

 

O.k. so then why are so many people interested in stroking their engine?

 

Yea, what he said.

Then you have guys like Todd making supercharged strokers.

 

Most people who consider building stroker engine have severe case of masochism.

 

For every 100 who talk about it maybe 1 actually does it. Even those who BOUGHT the cranks often never went any farther than that. If you ever see in person and hear Mark's car or Joe Fan 's you will understand the desire

 

So stroked 928 engines are like kit cars?

Lots of people talk about building one, a small percentage start the project, and very few are ever completed. In the short time I have been around 928's I have seen quite a few stroker cranks go up for sale.

 

Sometimes same crank sold over and over

 

You can never explain the benefits of a stroker on a messageboard or justify it, especially to non gearheads on a budget without a well equipped garage.
I've built and driven many cars over the years with turbos and superchargers. Some of them were amazingle fast and very rewarding to drive. A common desire during those times was to yearn for the simplicity of a big engine.

Nothing can compare to the shear satisfaction of a big displacement engine, it's pure and always there, they sound sweet too!

 

Forced induction gives you added power at maybe 4 times less cost than doing a proper stroker motor rebuild, so most people go with an SC.

A few of us are trapped in California, where putting a blower on your motor causes endless bi-yearly headaches on making your car street legal, while a well built stroker motor can be almost indistinguishable from stock other than having an unreasonable amount of torque...

My rods and crank are ready, and the pistons are due to arrive soon...

 

I think for most stroker builders it's more about the journey, for the boostards its more about the destination.

 

Or ridden in one on the track, then you'll REALLY understand the desire.

 

Well said Adam.
