How hard to get a E34 into the 200mph club?

[unesential]

An engine is capable of producing horsepower does not mean that it is. The boost fixed boost pressure only means that the capability is there. Actual output power is still controled via the throttleplate position regulating airflow to the cylinders. Yes it is possible to have a DD that is not floored to max routinely last and require a small rebuild however, if you are pushing that much power for an exrended period of time there will be more damage. This what is meant by full power hours. I can run full power for x hours or partial power for y(partial)=xhours.

i'd like to see you give it a shot. my dad dropped a stock s2000 in a streamliner and went 260. granted it was a lot lighter and more aerodynamic than an e34, but hey, i got my hopes high for you.

The only real way to know is to try, then taking the engine apart (if it's not allready done). But with a pull that long, this is a lot of heat to get rid of.
I aint saying that it is not possible but just that it need to be a serious engine. On a short pull the mass of the head and block can absorb most of the heat (when it makes his way to the radiator the car is probably allready decelarating). On longer pulls, the mass of the block and especially the head, can't absorb all the heat generated, shure aluminium have a good heat transfer but not a good heat retention and a low melting point. After a 45 sec pull, your motor may look like a pressure cooker. So to acheive this I would not use the inline 6 (and it's the one I prefer to drive) At least a V8 and if ever possible a V12, why ?? Just to spread the heat, just compare a L6 and a V12, and say you need 900 HP, well every heads have to handle 450 hp yelding better chances of staying together, add a huge flow of coolant trough the whole block oil sprayers under the pistons and on the valvetrain is definitely putting more chances on your side.
Best crank/rods/pistons that money can buy maybe it can be done without nuking the engine. Choosing the best engine for an application is the best insurance that somone attempting this can have, even if it's possible to do it with an inline 4 !! Yeah why not a huge turbo, nitrous, 4 spare blocks, a guy can handle it. It shure is cheaper to try this from a V engine, that is my personal opinion.

Fun thread by the way

I wonder if that 1200 hp M5 has ever top a top speed run?

Take some wait out of there, and then TT it

[Uriah]

but at bonneville the long track is 7 miles so you need to do it within that length And then if you go over 200 they impound you car overnight and you can only change the fluids ,injectors then you have to back up the run with another 200+ MPH in the moring to get into the 200 mph club......i know this because for the past 4 years me and my father have campaigned a 1934 ford 3 window coupe with a 572 C.I. fuel injected Hemi with 1000 Hp and 900 Lbs of torque. and do to aerodynamics we were only able to reach 191 mph but thats still pretty fast for an unchopped steel bodied 34 Ford if you ask me.

You guys know Larry? He's got the red 1998 Mazda RX7 with a Corvette engine and trans running a little nitrous. He's pretty active in the ECTA (East Coast Timing Association), and has a Green Hat with a 204 pass, and his brother ran 202. He's ran it at Bonneville, and the car he had before that was a 1979 Volvo 242 that ran 173, also with a SBC. They've the Waddell Brothers Shade Tree Racing. I keep telling him to stick a Ford in it if he ever wants to be fast...

He's evil, I work with him, and he gives me ideas.

I don't think there's anywhere in Norway that's long enough for a 200mph run.

[angrypancake]

for aero, toss on an Alpina front bumper. they've had that bitch up to 180+mph, and that was back in 1989.

the 6 speed transmission from a euro e34 m5 will match up to the m30 powered 535. if you could get 6th gear to go really long and fabricate a twin turbo setup, it's probly possible. we should do a bf.c 200mph challenge.

[540Greg]

Check out the top car on this page. It's only 198mph but that's pretty close.

they way i see it is, an e34 could easily do 200mph if it were built up enough.. im mean look at the e60 m5... 500hp, and the e60 is fucking huge! Imagine what is possible with 1000 hp and a lighter e34.

Here it is the answer. http://cgi.ebay.com/ebaymotors/BMW-A...ayphotohosting

this is true but i think after 100mph i think it goes from power to weight ratio to power to areodynamics ratio...but if a 5000lb car with 550hp can top 200mph surely a 550hp car that weighs 3500lb can top 200 its all in the gearing and differntail

you ar right, in a way , but you need TORQUE to turn those tall gears, adn especially to accelerate the car up to top speed before the start of the measured mile.

From DA Motorsport:

"S50B32 is not a "dyno queen", where we make 1.000 horsepower and then we decrease power on the road and track. 1.000 horsepower is used 365 days a year.

I hereby request a dyno vid of said engine pulling top gear at full boost at redline(or within 500 rpms of it) for approximately 2-3 minutes continuously.

thank you.


On a personal note:
I wouldn't want to run 200mph in an e34 honestly, though i have friends who can do it in their supras etc... 170 on a stock 97 TSi AWD was quite scary enough for me to puke my guts out.

[gboezio]

It seems that many 500-600 hp cars with decent aerodynamics can acheive this, for us, I think that a good 700-800 hp should do the trick

Every BMW I've owned has had a, ah, optimistic speedometer. I'm also not buying somebody driving (or a passanger) taking a pic of the speedo at that speed. On the first pic, you can't see the economy gauge needle, on the second one below it, it's like halfway.

For now, I'm gonna concentrate on running a timed 150mph and go from there.

[5271990]

1 minute @ 200mph is 3.33 miles. That's 3.33 miles to walk picking up bits of the engine then!!!

How fast does Redfive go with 335rwhp?

YES i have seen that car out there before ....does he usually go in August like us or does he go later in OCT.?

I'll ask him Monday. I THINK he's going back in '07 as well, but he normally runs in SC at the ECTA events which is where I might try it next year to get my feet wet, so to speak.

True on the speedo, and some of these have to be dyno pics, but that gauge below the tach is an oil temp gauge on the M5 and apparently on the B10...not the economy gauge on the lower-sped E34s.

I posted the link of their website, go find one. This company has been around for years... read up on it and ask some of the ///m3 boys whether or not they have heard of them.

[5mall5nail5]

I think about 500 - 600 hp with a 525tds differential will put an E34 to 200 mph

You guys are talking about adding 6 gear boxes etc. There is no reason to have a 6 speed - the final gears are not that much lower ratio than with a 5 speed. Hell, a 2 speed with a 0.90:1 2nd gear and a 2.50:1 rear end would do just fine if its a true salt flat car.

[Cacatfish]

A chip and an intake ought to get you to 200mph!

Im being facetious... but until someone proved to me that it would endure at 1000 hp for SEVERAL continuous multi minute runs (as opposed to a dyno sweep or 1/4 mile only) I wouldn't bet on it being suitable.
You don't need 1000 hp anyway... how ya gonna put it to the ground? Especially when running the narrowest tires possible?

i don't think wheel spin is much of a factor at bonneville

[Mr Project]

Actually, it's a huge problem. And the surface of the salt flats is something the racers try very hard to protect, so that's one of the reasons why you see big diesel 'pushers' getting the race cars up to speed. Traction problems at low speeds make for easy wheelspin, which is a big no-no on the flats. (ok, sometimes it's the gearing of the race cars)
