Question: how do I make my Porsche faster?
Answer: how much money do you have?

Surprisingly, the 928 does have an option to increase HP. The aftermarket has developed a supercharger for the shark. I know nothing about the details - if you just slap it on or if you have to do a bunch of work on the bottom end to beef it up for the extra boost. And I don't know how expensive it is. There are several threads about superchargers on rennlist.com in the 928 section.

Speaking of RL, there's a several page sticky note for 1st time owners that goes thru a lot of issues with the 928 and provides links to vendors. Worth spending the time and reading it all the way thru.

The biggest issue when buying a shark is knowing the timing belt age, mileage doesn't matter. 5-6 yrs is generally considered the useful age of a timing belt. If it needs replacing, it will be around $2500 USD and it's a complicated job, not your typical timing belt job. The one item in your favor if you buy an older version of the 928, those engines are non-interference engines so if the belt breaks it won't cause catastrophic damage. That's not the case with the 32 valve engines - if the timing belt breaks, valves will bend and quickly escalate the cost of the job.
