I feel dizzy, do you have any pictures?

Thanks,

Polo is a 4 cyl engine roughly based on the 911, and uses 911 parts including the heads. Pretty cool motors.

May I ask what exhaust system you have installed.
Thank you

That engine is a beauty Jeff.

Jeff, if you don't mind I have another question, what size valve did Bill install on your heads.

Thank you
Ralph

50 mm intake w/8mm stems; 42.5mm ex. W/8mm stems

The confusion is understandable. The motors are from Dean Polopulos hence “Polo.” Do yourself a favor and Google “Porsche Polo” and check out the videos…and turn up the volume. The sound is pure nirvana.

Wow, looked it up, it's a pretty involved beast, could probably spend weeks reading and still only scratch the surface. Very cool indeed.

Go to www.polomotor.com
The Bahama Yellow 912 is mine. It makes maybe 190 hp. It's quick. Jeff's 912 will be a rocket.

Message I get, hopefully they paid their bills.
