how much hp and torque?
any video? |
at 1.6 bar she's around 900 at the wheels in HP, tq is around 820
at 1.2 bar which i ran for the weekend i picked her up before the triple plate tilton let go, we were at 576 ft/lbs of tq at 4,400 RPM and she peaks at 6,500 for tq. I need to get the dyno sheets, the shop was setting the AFR's for safe running. The dyno sheet I loaded is 634 rwhp at 1 bar and 605 ft lbs of tq vids of us messing around: http://www.flickr.com/photos/3329043...7621377134776/ |

Very Cannonball Run pre Ambulance! Nice work J.J.
|
such a beauty......:eek::eek::eek:
|
Been following this on Rennlist...insane! Congrats!
|
That's awesome! How long did the build take?
|
Started in July 2007 looking just to get a 935 style front bumper...they sent the wrong one that was 3" wider per side...so it all kinda snowballed into this. So just at 23 months.

Your car is pure sex! Congratulations and enjoy :)
|
cool build
|
Well i just finally remembered i did take a pic of the rear wheel that had the most slippage inside the tire...so enjoy the insanity and to quote Keith and Aaron at Zuffenhaus "Its an insane problem to have, but a problem none the less...we could always install a set of bead locs...hahaha"
Hard to see the white paint marker, but you can see it in the close up. https://farm3.static.flickr.com/2547...33159e52_b.jpg https://farm3.static.flickr.com/2583...bfdce9e9_o.jpg |
That last pic is nuts!

That's a beautiful car, and a tremendous effort in terms of the build. Reminds me of the great days of the Porsche Turbo 935.
