I just been reading the new F1 mag, going on about the engines, and how they aged the blocks by chucking them outside for a year and pissing on the blocks lol, they also said the 1500 bhp was a guess as there dyno only went up to 1200 bhp so it could have been more or less they just extened the line and guessed. The used to plug in the "Hitler Chip" on the last quaily session and disconnect the waste gate. 50% of the time it would blow up, "the block would spilt all the way from the bottem to the head, the head was still in the car, but block would be on the road in bits" i pissed my self at that remark

the blocks were standard 4 cylinder BMW 3

Absolutely true - the blocks were 'seasoned' blocks i.e heat cycled on low powered engines then normalized by being urinated on repeatedly to relax the grain structure before being machined and run as an F1 block.

The wastegates were welded shut for qualifying - between 6 and 8 bar of boost was the norm...

Running benzine as fuel...

Great times

MAD EVO 4

we run the old mclaren f1 tag turbo cars, in race trim they have a push to pass button which takes the boost up to just under 5 bar

Thats only a carbon heatshield, there was a thread started by Stavros about it, and it turned out thats all it was, a carbon cover


Nice though!

What mag is this Johnny? Sounds interesting! lol

wasn't their some thing to do with milage aswell, 100k mile engines?

BMW motors wasnt monoblock, but some others were. Which, I cant remember.

The blocked/removed the wastegates on a lot of em in qualifying, just let the engine boost to whatever it could.

Never ran as high as even 6 bar, never mind 8 bar. Not even in qualifying, IIRC even the BMWs only ran 5.5bar max in qualifying, and they ran more boost than any of the others by far.

And yeah, most the cars ran on fuels that were 90%+ Toluol (ie Methyl Benzine)

it's nicely on a dizzy

The block is based on the M10 engine...

The bmw blocks also had slots machined into the deck face to allow the gasses to escape when the head gaskets blew, this allowed them to continue cos most of the time the water stayed in the engine!, Brian Hart was the guy who integrated the head with the block on some engines but the original design was down to offenhauser apparently.
