How much Power does our 152,000 mile E92 M3 really make? - Dyno runs + Spark Plug Change

During the first drive Imran said the car felt a bit flat to him, and having driven hundreds of different E9x M3's over the years he tends to have a pretty good feel for them.
So before we get started, lets put the car on the dyno and see just how much power its making!

WOW, For 152K miles, it did really well, shows how good these cars are when they are looked after

Dang man, you just spoiled the result for me right from the first second of the vid Nevermind though, cuz I love this car and this engine as well

[@pabloemms]

So interesting explaining the relationship between ignition settings and power made, and what difference such a simple change makes.

[@hojnikb]

I'm actually surprised that such a drop in ignition timing on the top end (10* almost) didn't result in much more of a power drop.

[@dearuoas3467]

I would definitely be interested in the 102 octane comparison, having used it during my last 2 trips to Germany. My car felt much stronger after an extended run on the autobahn.

[@vab120]

For a 11 year old e92 m3 it’s more than decent

You da champs for not splitting this into a before and after vid. Although it'd be interesting to overlay a dyno run from your other E92.

Weird cause the S65 is known for making less hp than claimed.. in reality they had 400ish instead of 420

Excellent video and info. Got me thinking how long since my plugs have been changed on my E92 M3 now. Can you do a follow up with a Evolve tune added too please.

[@EvolveAutomotive]

We will tune it in good time, but are focusing on the suspension/maintenance first,

Props for the less tangible aspects of your channel. No unnecessary footage, good music, clear info and a dope intro.

[@hirojj.1723]

Awesome! This is amazing data and I've got very interested in this evidence. Spark plug is crucial parts for engine performance isn't it. As far as I know BMW recommends spark plug must be changed every 37kmiles. What is your recommendation for spark plug change interval?

[@EvolveAutomotive]

If wanting peak performance every 10k miles

[@iankaye9801]

I predicted 398 earlier today and mentally after the spark plug change 406, so 411 was a bit of a surprise, I suppose the bottom line is that if one spark plug gets oiled up you need to keep an eye on it

[@treeightoh3003]

Great video! Shops around my area were asking 400-500 for spark plug changed! Ridiculous anyways seeing a few videos and especially this ones confirms its not that hard of a job except the 2 far back plugs in the back near firewall! Nice video I have a high milage m3 as well looking forward to more content!!! Would u change the coil pack in the e92 or just wait for It to fail??? The 200 price per coil is draining on the wallet lol Thanks!

Please explain why car prices have gone up, I don't understand it

[@samcourt6228]

@@ip7590 it appears to be a combination of things; no new cars on crazy cheap deals flooding the market like normal, new cars on crazy lead tunes, people not eating out / going on holiday and not really commuting so treating themselves to something tasty. I had been looking at swapping my M140i for an OG M2. Before COVID, a decent AUC was about £26k for a decent spec’d car. The same cars now are over £31/2k. Sod that. They’re older, with more miles for more cash. E9x M3’s have firmed up too. WBAC etc are offering crazy money for cars; the offer for my 140i was too good to turn down sonics gone. I’ve bought an old 130 for a bit in the hope that prices soften a bit.

[@Peanutdenver]

@@samcourt6228 Here in the States used M cars like an F80 M3C for example are almost 30% higher pre-pandemic numbers. Chip shortages are also creating an uptick even if it doesn't directly affect that particular manufacture as perception is reality with the car market. It's suppose to normalize come winter 2022ish, so most people who understand the issue and do not absolutely have to have a new or used car are waiting. I've seen 2017/2018 M2s with 20k miles on them selling for $55k/40k pounds...its crazy.

[@samcourt6228]

@@Peanutdenver yup, it’s mental hence why I’m sitting it out for a bit. Buying now seems madness. If I bought that M2 that I’ve been hankering after, I’ll end up taking a massive hit when I eventually get bored and my head is turned by something else. M4’s were plentiful pre COVID a d at similar prices to an M2, looked great value. Now the only cars in budget are the earliest examples whereas I’d want at least a 2016 car due to the revisions made. I’ve been surprised at how much I’ve the old 130 so far though. I don’t miss my 140 in the slightest.

Another great video Imran , Plugs make a world of difference, especially after 40k miles, I have a 32 yr old Volvo and it was sluggish and so i did an oil change with plugs, rotor , distributor cap and air filter with a fresh tank of 97 RON fuel CDN GAS SUCKS , i didn't gain any power it just ran smoother and i now get almost 50 more miles to a tank of gas, so it was beneficial and it all cost less than $ 100 🏎

Do you think the plugs would make a big difference in a E46M3….???..& grant video loving the informative information that you give… KEEP up the good work…

[@EvolveAutomotive]

I don’t think you’d see a difference like this because it does not use ionic knock detection. But a fresh set of plugs can never be a bad thing.

[@ataorkunoguz5451]

Awesome video guys as always, I predicted 400 after the change of spark plugs, 411 was a pleasant surprise. I have a question by the way: If you had increased the rev limiter to 8600, would it make additional power without changing anything besides rev limit? Have you ever tuned an S65 with Schrick cams before? Thanks

[@hojnikb]

I don't think you'd gain much from that, look at the torque figure on their graph. You need better breathing before you can get any real power from more rpm.

[@EvolveAutomotive]

You would see a small gain just by raising the limiter yes. In our Software we can raise the limit if the customer wants, to see a little more top end.

[@activemonkey7325]

Who the hell goes to a DYNO and gets "flywheel" horse power. What did it make to the tires! This is like measuring from the base of the balls instead of the top of the shaft. By this way of thinking, by B5 S4 made 465bhp & 542tq (349awhp & 407awtq / .75) when it was on a mustang dyno. I mean it sounds WAY cooler, but it's anyone's guess on the drivetrain loss.

AFR before and after was the same as the ECU is targeting a certain value, so is adjusting fuelling as necessary.

[@Omegaman1969]

@@EvolveAutomotive How many maps does the S65 have for fuelling ? A couple of part throttle closed loop and a WOT fixed value map ?

[@hojnikb]

@@Omegaman1969 It also has ITBs, so that complicates maps a bit too, since low load/throttle will get inaccurate data from map (not sure how it is with MAFs).

[@Omegaman1969]

@@hojnikb True it has ITBs but all 8 share a common plenum and it doesn’t have a MAF, I’m pretty sure it’s Alpha N with map compensation . I’m just curious as to why timing is closed loop ( plug monitored ) at WOT if the fuel is a fixed value . There shouldn’t be any need to vary the timing if the mixture is fixed .

[@hojnikb]

@@Omegaman1969 I'm surpised that a modern engine like S65 doesn't use MAF, but i'm sure there's good reason for doing so. As for timing at WOT; plenty of reasons why you want to still adjust timing. Bad fuel, high IATs, poor plugs etc...

Would the car benefit from me ignition coils? How often should they be changed as a maintenance item?

[@chrisg4rr377]

They aren't classed as a maintenance item. Typically you would change them if you started developing issues. But at that mileage it wouldn't hurt to change them apart from the cost. You would be more worried about an injector failing and dribbling too much fuel into a cylinder

[@EvolveAutomotive]

Generally with an ignition coil they’re either working or not, wouldn’t expect to see a performance increase like we saw here. It’s the kind of thing you could change for peace of mind, if you were about to do a big trip etc which would be ruined by a failure etc

[@TheChrosty]

[@johncreedon1833]

How often would you guys recommend changing the oil on an e92 ? (Daily driver - never tracked)

[@EvolveAutomotive]

Every 10k miles but realistically can never do it too soon, so just what you think.

[@jgripen969]

If an engine’s had its oil changed regularly, it should actually produce MORE horsepower as you rack up the miles. The cylinder frees up and become smoother and smoother as the piston travels up and down.
