That is sooo awesome, they should run for super city mayor, id vote for em. "Your a Firefighter? Your a *wit dude"

^Seems to have a bug with 6 cylinder engines.

Found this too, but havent played with it yet - http://dairally.net/daihard/chas/MiscCalcu...rs/DaiPipes.htm

Random volvo forum for the equations, theres references to them everywhere but this makes the most sense - Theres about 5 different exhaust diameter calcs from googling. Rethinking mine I should probably re do it for a peak of 5900 RPM to work with stock max power.

Found some equations, did some maths, and some assumptions Tuned for 5500 rpm peak, pipe sizes rounded up 6-2-1 (better mid range) Primary 16" of 1.5" ID Secondary 14.2" of 2 ID" 6-1 (better high rpm) Primary 30.2" of 1.5" ID 2.25 to 2.5" single exhaust (depends which theory you use..)

Looks like a friggin Pipe organ

Tractor manifold = Cheap to mass produce M50 Cast Manifold = Cheap to mass produce Good exhaust manifold (M3?) = Not Cheap to mass produce M50/M52 exhaust stock manifold might as well be off a massey ferguson. Most Japas have better designed cast manifolds! Pod filter aint gonna do much but make noise, noise is cool though , and many stock intake manifolds have chambers built into them to give the same effect as a tuned length intake, making more power at X rpm. Some clever fellow has worked that all out, removing that may not help performance. The whole idea is to get all the sucks and blows to help each other, so that as one cylinder sucks/blows it helps the next cylinder suck/blow. Getting all the pulses to work together at X rpm is done through the the length of the intake/exhaust. Its not just as simple as big hole in the front + big hole in the back to get the most air in/out. Turbos make the whole intake/exhaust length tuning pointless, as the turbo/compressor wrecks all the waves, and the intake/exhaust charge is getting shoved through the engine anyway.

I concur, Ive seen better looking manifolds on tractors.

Anyone got, or found, any real world numbers on M50 exhausts. What works, what doesnt, recommended diameters and header lengths? Im thinking two equal length 1" branches of 3 into 2 then a single 2 1/2" pipe to a single muffler, and likely a resonator in the middle to quieten it down. Thoughts?

Im struggling to work out who is more retarded, the clown who did that to it, or the munter who wants to buy it. Problem with situations like these is the poor E30 stuck in the middle...

Wait a week for me too bolt new one on, and you can have mine for $20, 4 spoke poverty pack job. If I can find my 22mm socket you can have it this weekend

Double post, my bad.

Cheers - I just pulled off the door trim to have a looksee, rods to both the solenoids have been disconnected (and so has the boot and gas flap) Moving the drivers side solenoid triggers a sad sounding buzzing noise from somewhere around the A pillar, passengers side solenoid feels locked solid (cant move it by hand) Is the passenger side solenoid supposed to be jammed like this? Im wondering if Ive got a flogged passenger solenoid and thats wrecked the central locking computer, previous owner obviously just diconnected it mechanically... Moving the drivers side solebnoid without flicking the microswitch might have been a bad idea in hindsight

This is my latest RW, custom designed by Mr RW for me, so im a bit of a fan Maiden flight in tokoroa with the rocket man (Bruce Simpson) so I was being gentle with it making sure nothing exploded/melted, its doing around ~180 mph. Datalogger melted so I didnt get any pitot static airspeed numbers which sucked. This one is sitting at 2.2kW, previous one smoked a bugatti veyron to 140mph with 1.4kW, so this should deal to the veyron SS!

Its getting cheaper and cheaper. I have a few ritewings, none FPV (yet...), A zephyr can be set up for $500, add another $400 for an average radio, and ~1k for FPV gear and do the same as the vids. Same as anything though, you can spend much more or less To do it "full bling" roughly double the price, but you'd have HD FPV goggles and a fricken sweet setup! NZ CAA/NZMAA law at the moment doesnt really cover FPV. "legally" you cant fly beyond visual range, and you need a spotter watching your plane and ready to grab the sticks incase it goes pear shaped. This has been around awhile, and its pretty nuts -

Im the stig.

Totally off topic, but this made me say Wow, its EPIC http://vimeo.com/14541093

Added benefit of never having to vacuum your car ever again, just hit the gas pedal

Is that a TT lexus V8? Ditch the bags/interior/wheels/pinkness and it'd be pretty wicked!

Looks pretty trick, whatya rekon? M stripes might be added to my todo list

Do E30 coupes have central locking standard? I only ask as I found a solenoid lock thing for the gas cap in my car, but AFAIK, my car doesnt have central locking, or it doesnt work

Chur thanks!, that looks swheet, wonder how it would look on a black e30 coupe, my photoshop skills are shite

Stumbled across this on realoem, and dont recall ever seeing them on an E30, anyone got a pic? http://realoem.com/bmw/showparts.do?model=...hg=51&fg=25

Might be a repost, but this thing is nuts
