BMW V8 M60 and M62 FREE PERFORMANCE INCREASE

- The BMW M60 and M62 V8 Engines are used in the E31, E32 and E38 - and there are ways of increasing performance from these engines that cost you nothing - and here's how!
Did you know that the BMW 840ci, 540i and 740i have an embarrassing 0-60MPH acceleration of somewhere between 7.1 and 7.4 seconds? It's a bit sad that they accelerate no quicker than a 118i M-Sport with the tiddly 4-pot engine!
My E31 840ci does it in 6 seconds - and this video is all about the things that increase performance, and those that completely messes up engine performance!
This is Part 4 of a four part series - today we look at stuff that costs....nothing!
Timm's store: www.amazon.co....
I just found out my range Rover HSE has a m62 bmw engine and now I love it more
Good man!
Really helpful info on the fuel & battery front especially when stored for long periods
Thanks Paul!
Timm, I really appreciate the work you are doing and sharing! :-)
If you want to continue with this series, I have for you some material for part 5, that you haven't mentioned. :-)
1) There is a lot of problems in M62 with the regulated thermostat. M60 had a normal 85 degrees Celsius, but in m62 to save fuel they have made a pressurized cooling system working at 102-108 degrees Celsius, but with the possibility to go down to 85 as you floor it. Regulation (heater, socket, or cables to it) often fails (every 3-5 years I would say from my experience) and the only working part left is a mechanical thermostat that runs at 108, which is not good for performance (but good for fuel consumption). That is assuming temperature sensors all working ok. You can diagnose the regulator in the thermostat by:
a) measuring its resistance - shall be 10-12 Ohms depending mostly on the quality of your multimeter,
b) checking all the related engine diagnostic codes
c) checking the engine temperature changes at driving (Myself having OBD2 in my e38 I use a dongle with the Adnroid app TorquePro).
First what you can do is to replace the faulty regulated thermostat, second is to buy an aftermarket regulator for M62 with the lower 85 degrees Celsius temperature (they cost about 100$, so very similar to the regulated ones). As I remember the e32 thermostat is also a replacement and fits (double-check it). Fuel consumption will be lower but performance shall be better ...at least in theory, but at least it will stress out less your cooling system, which fails quite often...
2) If you are running LPG (which is 100 Octane) use as well 98-100 Octane fuel in the fuel tank, not to retard the timing. This idea came to me thanks to this episode! :-)
3) Using LPG which has a higher ignition voltage and stresses much the ignition coils, use special spark plugs with the reduced distance between electrodes like "LPG1" spark plugs from NGK (or similar like BKR6IX if I remember well - double-check). They really do the job.... that is assuming you have a very good quality LPG system working perfectly (two of two-stage very stable gas vaporisers, very good injectors with high flow rate, a good computer, ideally a self-adjusting one by reading OBD2 information), which is not so common.
4) If you are about to fix your transmission (mine 5hp24 fails every 130kkm), consider buying a hydrokinetic converter from a sport version S204A. It is a different one with higher idle speed giving you a better start of the line. It is still available from Sachs, at the price of about 300-400$, so it is worth considering when changing it.
Thanks for the info Tomasz!
Both of our E38's have the original spare with original rubber, never used! I will be pulling those today!
Good plan!
stop forgetting the sublime e39 mate!!!! I adore my M62 equipped 540i and greatly appreciate your skill and knowledge on the V8's. Now with my exhaust mods, I feel like Mad Max every time I put my foot in it here in Canada where the right angle crank still rules..... this sweet flat plane sings like a lion.
Sorry, the only reason I forget to mention the E39 is that I never owned one! Sorry to disappoint you though, the BMW V8's are all crossplane!
Interesting content! In Germany there is ARAL ultimate with 102 oct. I always use that kind of fuel and I dont mix it with other petrol. My M62B44 now has new spark plugs and new ingnition coils from BREMI, and as you told in another Video, new timing chain tensioner, new oil und filters. So, this car runs perfektly, it sounds beautiful und it makes me happy every time I start it. Now it has 327.000km on the clock and I drive it with less than 11l per 100km. Yes, that makes me really happy. Thanks for your Videos, Tim.
Greez from Germany, Till
Thanks Till! 102 Octane, it would be nice to use that! I notice that Shell V power is 100 Octane in Germany where we get 99!
Wo hast du deine Steuerkette machen lassen?
That e31 is so lovely car. So nice you drive it daily and make the world better place to be :) Top knowledge as usual, thanks for the video!
My pleasure!
Nice one Tim. Those puny little corroded hidden ground straps on the engine and exhaust are often neglected on BMW's. The voltage drop can lead to slow battery recovery and anomalies of many varieties.
Thanks for the info Jason!
Good video. Maybe too deep in technical details for somebody but i found it interesting. Thanks for this lessons. Regards from Spain.
Thanks!
Love this guy, understood everything and took away a few tips, thanks🙏🏽
Great to hear!
30-50 HP loss from a "cone" filter???? NO WAYYYYYYY that's accurate. Plus the sounds literally transform the car!!!!
All sorts of great tips. I have a 95 740 il , 140,000 miles. Won't start, now it won't even crank. I tried your flooded engine tip, and I think I scorched the starter. Either that or somehow the EWS won't let it even crank. Have replaced just about everything I can, CPS, fuel pump, coils on and on. Am about to throw in the towel,,,,
Did you check grounds?
Super m60b40. 👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼👍🏼
Can't beat the M60!
What would you recommend for a m62TUb44 engine between:
1) Shell VPower 91 Octane (I am in Canada) no ethanol
2) Petro 94 octane but has 10% ethanol
I wanna make more power but am not sure if introducting ethanol will cause issues. 2001 BMW 540i
Great series!
Content creating while headed to work? Efficiency
I'm also overtaking inferior cars at the same time!
Timm, I’ve got all the boxes ticked when it comes to getting all I can out of my M62. After a while, a steptronic m62 leaves something missing…. Perhaps a manual s62 is the answer but the M Comes with caveats I suppose…
Any car with the M62 (E31, E38 and E39) is old and will never be as sharp or as fast as a modern car - and sticking an S62 (although the obvious choice) may make it go a lot faster but the chassis will not keep up. I drive a 650i and an 840ci and I prefer to drive the 840ci even though it is slower and less precise it is of its age!
"its like having a fat person in the car" this made me chuckle way way more than it should have tim :)
I really shouldn't have!
Great content you the man!!!
Thanks 😊
Great video as always. Do you know if the different fuel octanes make as much difference on an E39 (M54b25) or am I wasting money on premium fuel. Also I noticed you shifted the wrong direction at first at the start of your video. have you considered switching the gear up/gear down to match your 650i and all newer BMWs? I've not done it do an E31 but I did the change to my E39. It Just consists of swapping around the two centre pins, purple and blue, on the purple gear selector connector.
Thanks! Yes, I should swap the direction - but it's something I never seem to get around to - could do a video on it! Yes, Octane makes a difference since around 1993
Lol. High octane is the correct fuel for a high compression motor. Learn a little about how compression and combustion works
Just watched all 4 videos and thankyou kindly, was very interesting. Couple of questions, why did the X5 4.6is and alpina b10 use the m60 inlet manifold on there performance m62's and is it more practical to run a catch can setup rather then constantly checking up on the pcv? Thanks again.
Putting a 4.6 m62 into my 1983 320i and these clips are proving to be very helpful.
The M60 manifold suits the larger capacity and engines that are tuned to use it - also where smoothness of idle isn't so important!
tim would pulling the battery cables off reset the ecu/ignition map
Yes, but back to fully retarded!
Great Vid as as always Tim. Quick question, I noticed you are trickle charging your car from the boot and not the connector at the front trunk - is there any particular reason or benefit - I've always done mine via the front but to be honest I can't remember why! Thanks
Thanks! Charge from the front or back it really makes no difference - it's easier to hide the charger in the boot though!
What are “HT plug boots?”
All explained here: www.meeknet.co.uk/E32/Plugs/Index.htm
Still doesn’t explain what “HT” means. I assume you mean the o-rings on the ignition coil pack boots at the spark plug end?
HT = High Tension (referring to the high voltage at the coil-over-plug unit boots)
I am tuning a 3.0l M60 with megasquirt and it keeps wanting more timing. I am used to a ford or chevy small block v8 needing 38 or so degrees total timing advance but I have this m60 up to 41 with perfect afr and it's still lacking some power. I would love to know what the maximum total timing advance is with the stock ECU tune.
Hello Drew, I had an M60B30 for years, max advance was 24 degrees at full throttle and 5500 RPM. 218 BHP was standard
@@TimmsBMWRepairsandInformation Thanks for your reply! Wow! That's a ways off from 40 which is where I found the peak power to be. Our best fuel here is Chevron 94 which I hear lab tests at only 87 octane. I found the engine to be lazy and a dog down low until I changed the timing curve. Spark plugs look perfect, no knocking! czcams.com/video/QPrNI1NKe7U/video.html
Hi, Excellent video. I have a 650i which I have owned for 3 years. Not changed the spark plugs yet. Which make and type would you recommend?
It's quite a job Michael, give yourself a bit of time - here's how it is done: www.meeknet.co.uk/E64/Timms%20BMW%20E63%20and%20E64%20Ignition%20Coil%20and%20Sparkplug%20Replacement.htm
Nice insight about octane number and retarding timing in M60. In my e38 with M62tub44, that I am running on LPG, it seems I shall use Vpower as well as the car starts and runs the first few km on petrol. Do you know what is the mileage in M62TU, that timing changes?
Really good information, but does all this apply to the E34 3.0V8 M60 models aswell?
It does Julian!
Greetings Timm, with the price of petrol, I'm now more interested in whether running 87 octane (in the US) is safe from the dangers of pre-ignition (detonation), then I am in outright performance gain of the higher octane. I have stuck to the lowest recommended in my manual, which is 89 octane, but I'd like to take advantage of the approximately 15-20% lower price attached to 87 octane, if at all possible. Do you think it is safe to run 87 Octane consistently? Thanks.
Hello Francis, 87 octane is good for lawnmowers, not great for the V8's which need the minimum of 89. 87 is likely to damage the engine...
@@TimmsBMWRepairsandInformation lol, thanks Timm, duly noted.
All engines sold in the USA since odb2 can use 87 without damage. It’s federally mandated.
Another great video!
Thanks Kelly!
Do you have any video on the secondary air pump problem on the M62tub44
The E31 with the M62 didn't get that system - but from experience on the E38 the usual problems are the pump itself and the vacuum-controlled valves
Hey timm, the 850i and 850ci are a lot more common in the states. I was considering getting an e31 and was interested about the common issues, and the preventative maintenance that could be done to prevent any major issues down the road. How much do you think I would spend on maintenance a year for a well maintained car (surprisingly most of the ones on the market here are well maintained but usually with a bit higher mileage).
Or should I just avoid this Bmw coupe and look at a different one at the same price? I really want one of these.
That's a difficult question - the E31 can be hard work sometimes and you really need to wade in and do a lot of the work yourself to make it financially viable. I spend very little - I think the biggest expenses this year was £300 to get it through the MOT due to a broken rear coil spring. However, the E31 is unique and well worth the effort!
Loosing 30hp from putting the blower on, or 30-50hp for a cone filter! What an absolute load of dribble! I was willing to listen to you waffle on about knock sensors but again a load of twaddle. Knock sensors are designed to retard timing, in the event such as bad fuel causing pre ignition, they're no designed to advance it, nor do not have the ability to advance the timing further than the DME/ECU's ignition maps, which were Tailored to the fuel available at the time. So pretty much any fuel these days will be more than sufficient enough to allow the engine to run as much advance timing as is programmed.
I will refer you to the owners manual regarding fuel specification: www.meeknet.co.uk/E38/1997Manual-7Series.pdf#page=26
"Fuels with higher octane ratings will
provide enhanced performance and
lower fuel consumption, while the use
of fuels with lower octane ratings will
have the opposite effect."
