My Ride: PTG2001 E46 M3 GT V8
PTG 2001 E46 GT V8 / Race Ready again

Just wanted to share.
In May of 2012 I purchased Chassis 004. PTG 2001 E46 M3 GT V8.
One of 6 cars built by BMW of North America and PTG. One of 2 V8 cars. A Carbon Fiber body powered by an E39 M5 5 liter motor. This is the first V8 BMW M3 to Race in North America and the predecessor to the GTR.
For those of you that have been around for a while this is the Bell Motorsports Car. Built specifically to beat Porsche in Grand Am racing. In it first season the car and team garnered 3 wins, 1 overall at Lime Rock, 5 podiums and 9 top ten finishes. Finishing 2nd in points for the 2001 season. Drivers, Hans Stuck, Boris Said, Terry Borcheller, Toney Jennings.
Just completely refreshed for Vintage racing by Tom Milner at PTG. This was the last car out the door at PTG. Finished as they closed their doors for good last month.
Setting up test days in April at VIR to shake down and do set up
Not enough room to tell the whole story here. Ill keep you posted.

Good question. I'm told the car is in the 2,450lbs range empty. Thanks to the carbon fiber body as well as components such as magnesium rear control arms. This was an early car and originally came with aluminum control arms. However over the years it was converted to magnesium. Lighter yes. But. Additional matinence due to potential electrolysis. We will scale the car at the track. I'll be happy to share data.
Next logical question. RWHP. Currently running unrestricted. 538 RWHP 389 torque. 6 speed Hewland Manual Gearbox. When this car ran Grand Am it was heavily handicapped. Carrying additional weight and air restrictors. Two engines were on hand. A "Mild" and a "Wild". Each used depending on the track. Even handicapped the car was still able to win.

The air restrictors Grand Am required took out approximately 90 RWHP.

Great car! I've seen this once or twice at Sebring at the HSR vintage races in previous years, and it was always one of the quickest BMWs participating! Awesome job on the resto, thanks for sharing!

Here is an old video. A fellow Club Racer out of Wilmington, NC. Danny Alvis used to own the car. This was filmed at their shop several years ago. It gives you an idea what the car sounds like. Honestly watching this video is one of the reasons I bought the car. Every time I got cold feet. I'd play this.

Turn Up Your Volume!

Hi,

I am very curious of how you get the alleged
538 ''RWHP'' which in English equates to
''Rear Wheel Horse Power'' from an S62 Motor ?

Assuming 15% for Drive Train loss then are
you seriously suggesting that the S62 makes
near on 600 BHP at the Crank N/A for an engine
that eats shells when revved past 7500 rpm ?

The BMW P60 B40 engine which was the genuine
ALMS 2001 V8 engine, and when run with the
32mm restrictors, as run, they made around
460 BHP, circa 500 ish without.

P60 B40 was also Flat Plane Crank, and was
very special limited edition Race engine that
would rev to 9000 rpm + and had
its origins from the Swiss Mader factory etc.
All the P60 B40 engines were recalled back to
BMW MS/AC Schnizter, hence why the S62 V8
sits where some P60 B40 use to.

Is your car minus the rear Subframe version, ie the
RTA's and Diff are effectively mounted directly
to the rear of the chassis/mono couque and you
have the 320 STW [e36 Super Tourer]
rear suspension with the suspension Rockers
and the blade/ARB set up, with the Mag Front struts
sat on the Grp A rod ended front arms ?

Great Cars, not sure about the S62 though as
the heart of the 2001 ALMS car was the P60 B40.
You could always do an ''Edlinger'' and fit an
Indy Racing Leagues 3.5 V8 converetd to
run on Petrol not meths !



Regards,

The Gorilla.

Hello
Thank you for your questions and comments. I'll do my best to answer what I can.

Let me start by stating that this car never raced AMLS and was never fitted with the P60 B40 engine.

The car was specifically built to run in The "Rolex Grand Am" racing series. Classified as a GT. Not an AMLS GTR which ran the P60 B 40 that you mentioned. As you know all of the engines were returned to the factory and are not available to the public. This car has "always" run the S62 from new. Which makes it much more attractive to me as the car owner as parts are readily available at the moment.

This car was an effort of 6 cars from PTG and BMW "North America". 4 of which ran S54's and 2 S62 V8 cars. The V8's were built specifically to beat Porsche in Grand Am GT class. The car you see here is one. The other V8 car is somewhere in Australia. I'm told it may have been destroyed in a wreck at Bathurst. Not 100% sure.
Somebody should start looking for it.

As for the horse power. I am simply a repeater of data that was provided to me by PTG engine builder and tuner after dyno runs. As for how they get that type of performance. They will not share their secrets with me. Note that the engine is currently running "unrestricted" a luxury not allowed race teams under various sanctioning body's. Also note that this car ran 2 different engine set ups while professionally competing. A mild and a wild engine. This being the later. Estimated engine life I'm told is 30-40 hours before tear down. The block can be torn down twice from new. Then its scrap. Typically the block will fail before the 30 hours mark on the second rebuild.
I am also told the drivetrain % loss may vary as the result of the Hewland 6spd straight cut gear transmission and the selected gear set. The car came with 25 different sets of gears.

As for the suspension and rear sub-frame. There is a difference between the GT and the GTR. The GTR being more developed. I am told that they share some similar components such as magnesium rear control arms etc... As for suspension. I'm told that it was specifically designed for this car. I thankfully have a large box of spares in case of an off track excursion. Beyond that I'm unable to answer your question without calling Tom Milner.

I am not an engineer or technical guy. I am however an enthusiastic car guy and driver. I truly like this car and find its history interesting. What I have attempted to do is refresh the car as though it was going back on track in. 2001. But. Taking the liberty of max available horse power. Why not enjoy the ride. As this car is currently a Vintage Racer it is not bound by any restrictions. Hopefully I have answered your questions

Dave
