    probably not! performance numbers inside

    from my archives, a Motor Trend road test review summary from March '94:

    '93 740i- $54,000; 0-60=7.4 sec; 1/4 mile=15.6 sec/ 93.6 mph; MPG= 16/22

    '93 750il- $80,900; 0-60=7.7sec; 1/4 mile=15.8 sec/92.2mph; MPG= 12/18

    I have a Road & Track (3/93) with the whole write-up of the 740i, their numbers are as follows:

    0-60= 7.0; 1/4 mile= 15.2 sec/95.5 mph; all other numbers are the same.

    Unfortunately, I don't have numbers from R&T for the 750, nor do I have any for the 740il. I believe the difference in weightfrom the i to il is 100-200 lbs.

    must be something wrong somewhere

    extra hp and torque along with a slight weight disadvantage the difference 1, would not be that greatand 2, if anything the advantage should be the other way around, perhaps it is in the final drive ratio

    But Consider this....A M70 engine can be installed

    with a Twin-Turbo (This was from the Dyno war in VA) to produce enough power that the V8 will have a hard time reaching (Unless an obscene amount of Cash is available). But this was only with a 7PSi boost and will go up soon to 12PSi. Believe me...after all the mods are done...there won't be any Ferrari, Lamborghini or AMG to touch this.

    BTW This is the wheel hp and torque and the 0 to 60 will be measured soon. The 0 to 60 measured with 5PSi boost was 5.4 seconds but that was because the stock wheel & tire setup had a lot of wheelspin and would not launch correctly.



    Now who want's to race this one?

    Uh Yeeeah, I think we're talking OEM here...

    This definately goes with my statement "Emotionally the V-12!" I don't know how much cash you poured into this thing. but It's probably more than most on this board care to drop into a car. It does sound impressive, but I bet it's more than the $600 it'd take to put a 3.64 diff and a dinan chip in a 740 to increase the margin by which the stock 740 already out performs the stock 750.

    Most amature race organizations would put you in a very different class than we stock people. You would be in a different class than those Ferraris, AMGs & Lamborghinis too.

    At 5psi your running the same 0-60 time as a Subaru Forester XT. That's a long way from the high 3's. Keep us posted, I'm curious about the future success of your project, and longevity of your engine. I hope you have very competent people doing this work.

    Good Luck!

    Yes..Very true...Plus the M60 can be Supercharged

    to 7PSi with no other mods to the engine and a 3.15 Diff will bring the 0 to 60 down to mid 4 seconds.

    I have seen this done but on a 840 with the same M60 engine.

    1991 750il numbers from Motor Trend Jan 93 issue

    0-60= 8.1; 1/4 mile= 16.0sec/91.8 mph

    That's a long way from 6.5 & 14.8! I don't know where the Ford Super Coupe Club of Iowa got their numbers, but they are so different from "the experts" that weather probably wasn't the difference.

    I can confirm the 1993 BMW 740i 6.8 15.3 as being from Car & Driver.

    And you confirmed that at least in the years they were both made the 740il had the same performance, and the 740i out performed the 750.

    But deep down, I do have some emotional (illogical?) lust for a V-12.

    Those numbers make a huge difference....

    on the year of car you are looking to buy. It looks like there might be an e38 750iL in my future after all!1988 735i 210k

    It's not a slight weight disadvantage

    It's rather big, actually. Put a honda 4 clyinder in your mind, it's heavy. now add your V-12's ignition systems, there are two as you know. the 740 has distributorless ignition. There's more of every thing actually. The 750 has separate systems for each cylinder bank, plus it holds more coolant and oil, all add to it's hefty weight penalty.

    As far as the differentials go, according to Dinan, if you use the 3.64 diff from the 750 on the 740, the 740's perfomance improves! As I said in another post on this thread, BMW purposly handicapped the 740 with a 2.92 differential, so they could continue to sell 750s at a $27,000 price premium. Who'd cough up nearly $30 grand extra for the same car with lower performance numbers?

    I wrote more, and gave evidence in a post above called "as I said, logically the V-8"; I included the url

    that makes the 750 as fas as the M5-IT'S NOT!

    they probably crossed numbers! Motor Trend has a 1991 M5 as follows:

    0-60= 6.5; 1/4 mile 14.9sec/ 97.5 mph

    they list a 1991 750il as:

    0-60= 8.1; 1/4 mile= 16.0 sec/91.8 mph

    Those Iowa Ford guys are a bit sloppy.

    my 740iL has leather all over the interior

    seats, door panels, handles, armrests, console, everything. I haven't seen a 750 with any different leather than what I have. Mine doesn't have power rear seats, but has everything else except the extra 4 cylenders.

    Certainly you can find highline or special build ones that will have refrigerators, double glazed glass, etc.

    I think the point has already been made, but all E32s 735, 740, and 750 are the same cars except the powertrain and drivetrain. Each of them could have been bought with any number of options. Many here have window shades and power rear seats in 735s. George Mann's former 735 looks just like my 740, other than his rims and tuned suspension. Mine is stock.

    Cheers

    larger valve area

    (1)they still have 12 cylinders
    (2)smaller lighter and more agile is it not what you were after

    (3)what i meant was with more cylinders the availiable valve area is greater for a given capacity, ie a 2L four will have less availiable valve area than a 2L six

    (4)engine weights m60 146kg M70 155kg 9kg= about 20lbs big penaly no

    740i Saloon M60 1690? 169? ? Disc/Disc ABS
    740iL Saloon M60 1750? 163? ? Disc/Disc ABS
    750i Saloon M70 1782 168 3.15 Disc/Disc ABS
    750iL Saloon M70 1900 158 3.15 Disc/Disc ABS
    where does the extra weight come from in the 750il over the 740il same body motor not much different could it have that many more options standard?
