RE: 1,200bhp for sale!
Discussion
1200 hp is pretty impressive, especially considering the inlet manifolds appear to be made out of the same 4inch box section that props up my workshop roof! Shirely, there's atleast an easy extra 40hp in better flowing manifolds. No wonder porsche got so far ahead!
Some may argue an extra 40hp would be unecessary. To this I say pish and paffle. The more he merrier!

Thats one of the McLaren M1B's i race prepare driven by Mike Wrigley at Spa last year, it's using a 5.8 chevy small block. Mike also drove our 5.0 M1C at donington last weekend. You wouldn't fit a Big Block into the M1B/C chassis.
The big block car we run is the March 717, thats 8.8 litre, which is the current engine size limit for supersports.
You must come say hello at one of the meetings Dinkel, your pictures are always great.

Pleeeeeeze give some details of that series! I saw a can am race at Donny some years ago supporting the WSPC 1000kms, Holy Sh*t was a fantastic noise! was sat by the curves when they did the rolling start and felt the ground shake!!
Truly awesome.williamp said:

Why oh why don't they bring Can-am back?
It was a tremendous series

well, it was until Porsche ruined it with their 917/30. Like the BPR series, unitl Porsche ruined it with their GT1.
Soit was alright when McLaren were winning every race?
Porsche turned and stuffed everybody, as always, because they are better at it than the competition.

Truly awesome.The big block cars race in the Orwell Supersports Cup, which has rounds throughout Europe. We have one race meeting in the UK this year, at Brands Hatch on 29th June to 1st July. There were 9 Big Block cars racing at the last round in Hokenheim. www.orwell-supersportscup.com/
You can catch the mid 60's 5.0 and 5.7 CanAm Lola's and McLarens etc. racing in the Masters series. www.themastersseries.com/typo/index.php?id=33 our next round for the small block McLaren's is again at Brands Hatch in just over 2 weeks time.

Hi John, will you guys bring da Macca at next Spa 6 Hrs again?

Love those cars . . .

Remember that
. . . after the Spa '06 Six Hrs finish BossCerbera and myself walked the paddocks. And after a brief and most enjoyable chat with Healey-meister David Grace we bumped into you guys again . . . still fiddling with ole orange. Great to see the car pass me at La Source the other day.

Porsche would have been nowhere without the dedication and committment of Mark Donohue. He put in hours and hours of test driving and educated the Porsche engineers on how to make an effective Can-Am car

yep, the only time i was sat down all day too. 
Look at the state of my clothes, that shockproof gearbox oil is as nasty as it comes. That was the box on it's way out, by the time i had it rebuilt with a new CWP and managed to get the gear cluster back together and onto the main casing it was 3am.
Exhausting that was as the box case was distorted when the diff tried to ram it's way out the side of the box so it had to be setup with the best compromise on preload/backlash to survive, but the gear cluster wouldnt slide in. Those LG600's are damn heavy.

After last few posts my "six penneth" feels insignificant but I've loved seeing CanAm cars running up the hill at Goodwood FoS. ..And yes the sound IS incredible. It has to be said that 1200 hp is not extraordinary when you remember the Turbo F1 cars.(quote Martin Brundle-" even then I wanted more power" ! 
) I wonder how CanAm cars compared to those in weight?
) I wonder how CanAm cars compared to those in weight? The Big Block CanAm cars with all fluids and 20 litres of fuel weigh 830Kg, they have 820BHP so has 1000BHP/Tonne. Whats most impresive about the CanAm cars is the torque they produce, which is much higher than an F1 car at 800lbft, with it having over 700lbft from 3500rpm to 7000rpm.
The earlier CanAm cars like the M1B are slightly lighter at 750Kg or so, but dont have the power of the big block cars with 550BHP. The change in technology between a 1967 car and a 1970 car is stagering, this was the period where CanAm really pushed ahead with advances in chassis design, going from tube frame to sheet alumium tubs with magnesium bulkheads, unstressed to semi stressed engines, downforce rather than lift, much larger tyres.... During that period the F1 cars were a lot slower.
These days the CanAm cars are lapping at very similar pace to the mid to late 70's pre-turbo F1 cars, at some circuits they are as quick as the group C cars. I think at Monza in 2005 our Big Block car would have been on the front row of the group C race, if memory serves me correctly.
When the F1 cars started to get turbocharging to work properly, thats when they took a big leap forward in laptimes. I know which i would prefer to drive though, those early turbo cars must have been horendous to drive quickly, turbo control and design was very stone age by modern standards.
McLaren tried turbos on one of their M8F CanAm cars as a response to the 917/30, but they couldnt make it work or hang together for a race. That car is currently running in the Orwell series driven by Michael Campaign, minus it's turbos.

I really hate that louwman museum guy for selling of all the racing cars he bought from the rosso bianco collection, this shadow was just one of many sports racers in that brilliant collection. I heard Louwman also sold of some TOJs, chevron the lot. As far as I know he only kept some of the really really old cars. Louwman collection seems to consist only of some stupid specially bodied ford T's, bentleys (great BTW) not my cup of tea!

Donohue was a great and a very talented engineer and development driver but to suggest Porsche would have been 'nowhere' without him is ridiculous in the extreme.
In 69, Jo Sifferts 917/PA had already run competetively in the series with a N/A engine and the 917/10 and 30 were a development of that car. Donohue helped develop the car certainly but Porsche had already designed and built it before Donohue and Penske came on board amd indeeed Siffert was placed 4th in the championship prior to his fatal accident in 71 in the development STP (again N/A) car.
