At last the rebuild is complete. Started life as a humble 1985 944 and was transformed into this 3L turbo charged monster by Albert Broadfoot. We took second in GTO in the Grand Am Rolex Series in 2000.
Grand Am trim...

PCA trim...


For years we have been trying to sell it with little interest... Well here she is again, now as a 2.6L turbo built on a destroked 3L 968 block. No longer for sale... Hopefully she will make it to the dyno this week.

Rebuild and refresh by Albert Broadfoot. Fresh engine, paint, and bodywork...

Hey, what are the benefits of the Broadfoot power pulleys?

Saaaaaaaaaahhhhhhhhhhwwwwwwwweeeeeeeeeeeeeeeeeeeeeeeeet!!!!!!!

That has to be one of the best looking 951's I've seen. Great job, and thanks for sharing.

Not 100% sure, but I would speculate that the main benefit is to reduce the speed that engine accesories spin. Probably most beneficial on a race car that spends most of its time at higher RPM's.

Gussied up engine...

Wow!

That thing is beautiful! Why is it not listed in your signature????

Surely such a monster deserves a place listed next to your GT3!

I'd love to hear a comparison of their on-track manners!



EDIT - Destroked to 2.6 primarily for compliance with PCA rules? I can't recall what the SCCA displacement limit is on FI cars...

What class do you run that in??

NZ951

Why two vac lines on the BOV? Why the shaped TB IC pipe?

The bay looks great in black!

Sloth

Your right... need to restore its place in my sig.

This car ran GT1s in PCA Club Racing... GT1 is a tough row to hoe. Dropping to 2.6L was in an effort to reclass the car to GT3 and to improve its drivability. No real comparison between the GT3 and this animal... the GT3 is a ball at the track but I still have more fun in a dedicated track car. Not sure where it would run in SCCA...probably in SPO or some other catch all group. I am also curious to know where it would class in HSR.

Sloth

Not exactly sure on either question... Perhaps one line is + pressure and the other is - pressure for the BOV. As far as the IC pipe to the TB, thats just how it is to fit to the custom TB... very little is stock on this car.

still running the balance shafts?

NZ951

What do you do for an ignition system? What coil type? GM?

Ski

That's some great work!!! Thanks for the photo's!

Sloth

Not sure, but I doubt it.

Engine management is by Electromotive, controls all functions.

Travis - sflraver

Sorry about that.. its wasn't a "if you were" but a "why are you."
There was a lot of debate on deleting the shafts and I was actually looking for a little input. From the under hood picture above they appear to still be there. I was just curious what kind of gains you had by keeping them on a car like that.

Sloth

Sorry Travis,

The logic behind the inclusion or disclusion of the shafts is beyond my general knowledge. I am not really sure if the engine is still running the balance shafts or not. I could be wrong, but I always thought that on a dedicated track car they would not be needed since the engine does not spend much time at any one RPM... like when cruising on the interstate.

Very nice!

I have been drooling over the Adel Wiggins flexible tube connectors in Racecar Engineering magazine for quite some time. Nice clean way to seal IC pipes.
