Porsche 928 turbosports turbocharged dyno run flames!

4.7psi dyno run, no intercooler: 407rwhp/400rwtq. Time for a stronger fuel pump, otherwise would have run higher.

4.7: car dyno'd 295rw normally aspirated, so nearly 5 pounds is .3 bar. .3 x 295 + 295 is about 400rwhp, so right on target. 14.7PSI would yield about 550-600rwhp considering the kit/fuel was appropriate for such a pull.

I don't know, there price isn't too bad, but if there is a better substitute to sts I'll be more than happy to switch to that, I haven't ordered the kit yet

@dom2471 check out my other videos: the one that starts with the front mounted intercooler & works back: great kit, fast spool, stealth, even on a lowered car (2+") it still has plenty of ground clearance. Is your's a 5-speed? Email me, I'll send you more pictures: Porschesolutions@gmail.com

86.5 car (5.0 32v US-spec engine). You'll have to run a LOT of boost to get to 400rw on an '81 car: probably 10-12lbs or so.

Hey did you do any engine mods to get to 407? And what year is that car? I'm ordering a single turbo from sts next week for my 81 928.

@dom2471 Why STS? There are turbo kits specifically for the 928 which cannot be seen, stolen, & make incredible power. Also, a mid-mount turbo allows you to run a full muffler (or mufflers) and cats if you need to.

4.7 psi? you sure you don't mean 14.7?

Wow, that's amazing, is that an early 32ver? Those numbers are damn impressive even for the 32v let alone a 16v Euro! What kind of tune was it in the first place though? I know alot of people complain about how 928's are slow/sluggish but many if not most of them haven't had a proper intake refresh for a while. I bought an 87 S4 a few months ago.

Where did you get your from? Or did you make it yourself? I'd like to get something very similar, if not the same to what you have. I like whole set up you've got going on.
