What about the dead area between the two intake valves? (The dead area between the valves and the cylinder wall is probably even enough to make no difference)

Or the cheap cams because the SOHC head is basically the same thing that BMW has used since the 60's and cams are relatively cheap.

And that raises the next point - why not just use a 2.0l engine to begin with? They made a bunch of 'em and you don't have to fuck around.

Pete, ever seen the combustion chamber on those damn things?
WIiiiiiiiiiiiiiiiiiide open.
How do you make compression when the chamber is so huge?
A shit load of their engines had substantial domes just to make 9:1
We really want to get the static compression higher than 11:1 so there something left over when we use a gnarlier cam with longer intake closing.

That's the thing with the 16v things, the chamber shape means we can get pretty high cvomp with just flat tops which are enormously detonation resistant, and with modest domes, again very tolerant when the plug is so directly overhear like 99% or 16v motors.

I'll buy that.

Since California is all funding this and funding that why don't THEY have a state sponsored rally program? They have a free pilot school, why not driving?

This is probably not the best time to ask them why they don't support a hobby that turns gasoline into redneck yodels, y'know, what with global warmifiying, and all.

Can't you stick in later things?
Look what BMW says of their latest thang:
http://www.totalmotorsport.com/Features/Cars/Display.asp?ID=28
The BMW P45 provides the powerful heartbeat of the BMW 320si WTCC. By contrast to the BMW 320i, the new car is fitted with a two-litre four-cylinder engine. As Theissen explains: “Our rivals in the two-litre class have always used four-cylinder powerplants, and that’s made BMW’s six-cylinder something of a special case in the WTCC. Now our aim is to show that we can also play a decisive role in the championship with the four-cylinder engine.”

The four-cylinder is lighter and shorter than its six-cylinder forebear and develops considerably greater torque from its maximum 8,500 rpm (as dictated by the regulations), without any reduction in output. The BMW P45 engine already delivers 275 bhp, putting it on the same performance level as its predecessor. The powerplant is mounted further back in the car, which again helps to improve the centre of gravity of the BMW 320si.

Okay, where to get good cams?

Looking into it more I guess I was wrong - they stopped using the engine I was thinking about in the mid 80's and started with something else. The older engine was the basis for the M3's engine and the later DOHC are of course different.

Which engine are YOU talking about? (And where to get good cams etc.)

A 325is just feel into my lap. Ex autocross car. Fenders cut for big f'ing slicks, and he was going to sell the bucks-up suspension and then just scrap the shell 'cos he got tired of blowing up the 6 cylinder engine (he was running one of them twirly things in the exhaust). Picking it up for the shell's scrap value.

So I'm now interested even more in this thread although I think the correct solution for the rear suspension is going to involve Sawzall, Millermatic, and a bunch of 16 gauge. I figure, do the chassis mods for the Escort style rear suspension, and if I screw it up, well the price of scrap is only going up, and it's just a BMW so I don't care about it. And if I don't screw it up, then there's a FUCK of a lot more room for a rollcage in a E30 than there is in an RX-7.

Check out Tim Taylors strut turrets. Still requires the sawzall and Miller, but you don't have to worry about the 16 gauge.

Found this on ebay today, I think I saw some heads also.

Some 1900 DOHC thing, short luttle bugger 'bout this long <---->.

I had somehow missed this article/link you posted for the new BMW 320. I think it may be possible to do an engine swap with a newer motor to an older car. I wonder what the powerplant would cost, and its availability. One thing I saw that from a personal perspective I liked a lot is the shifting mechanism and controls:

"Integrated strain gauges in the gearshift lever trigger a power signal. This quick-shift system cuts ignition during gear changes in line with the chosen configuration, removing the need to operate a clutch."

I would like to figure a system out for this type of operation. I have seen a "duck" clutch mechanism for shifting but never the type mentioned in the article. I wonder if this is a syncro or straight cut dog box that is necessary for this type of clutchless shifting?

Wouldn't straight cut gears be too loud for a beamer owner?

I guess it would depend on whether the beemer owner was using the car for street or track.

Here's video of that BMW World Touring Car in action.
It's a bit made for Roadfly
There's no cheezy commentator or cheezy music. Just the car.






Directions for consumption:

If you're in a big hurry and only have 30 seconds:
--FastForward to about 7:30. (Thats where the good action is.)

Watch the beginning if you want to see
--the engine dyno and in car dyno tests

The middle is test and tune at the track...

7:11 to the END is all business as its blasting around the track.

It's A. Zenardi's new ride! Sweet. I would like to get a set of handcontrols that he has. The Duck clutch and the throttle on the steering wheel. Although he can still use his right foot for braking. I will have to set brakes up on the steering wheel also for driving with both hands on the wheel.

Gear noise, what gear noise?
