600hp & TOO LOW Tire Pressures on BMW M340

[@samsonian]

Misha, sounds like it’s time for a checklist and/or a form you give to the owner with all pertinent info or online so they can fill it out ahead of time.

U definitely need to do a disclaimer. Instead of these guys wanting to be seen on KZbin, they need to make sure the car is in safe driving conditions.

[@r.d.9399]

Tire pressure should be tested before you set out on any track or high speed roadway. Edit: Great disclaimer 💪

[@agnttgr]

​@@r.d.9399 that's why modern cars have pressure sensors (direct sensors or through ABS system), but this BMW just has it turned off

[@Niko-xz5lk]

@@fonkyman I'm not sure. I know that the car sensors correspond within a few fractions of a PSI to my airline, so it's close enough for me. I use mine to give me an indication of when I can open her up with risk of lighting up the rears, it's been very useful since the tuning.

[@povilasrikteris]

Misha, could you maybe make some videos about tire pressures, how they affect understeer/oversteer, something about coilovers or adjustable shocks overall - how to adjust compression and rebound, how it affects cornering, understeer/oversteer, etc.? I believe that would be interesting for everyone and also must to see thing for those, who want to give their car keys for you to lap the Nordschleife.

[@The11HD]

I would definitely watch those vids!

[@unhuz]

and also how different types of tyres are happy with different pressures.. it's a neverending list of variables, but the more in depth you go, the better we can prepare.

[@pacoflyer]

I'd watch a basic track tip video explaining hot/cold. I've tried to keep mine to stay at the door levels hot, but it seems a bit lower is ideal? Misha help us new people!

[@tristanmayor6302]

That car absolutely rips through the speedo! 60-120mph so many times, that is definitely a legit 600hp. Also the H&R ARB pairs have a relatively very stiff front one, which may actually be the main understeer culprit, possibly more so than the tyre pressures. To be fair to the guy, the pressure issue wasn't out of negligence, just been given bad advice

[@skrypka]

Agree on this, Anti roll bar effect is very little known, especially on the Nuerburgring - maybe they are not required here.

[@Friendroid]

How is it not negligence if he's the owner and he's on the Nurburgring? Maybe acceptable if he had just taken his driver's license and was driving his dad's car to the supermarket.

[@Gobbbbb]

@@Friendroid More ignorance than negligence it sounds like.

[@stoneeh]

First and foremost you can't just randomly throw mods at the car and expect them to work harmoniously. You have to know what you're doing, which effect which mod will have on the whole car / setup. For example with an ARB you might then have to adjust suspension and tire pressure.. or maybe it will not improve driving behavior at all. I have thrown out mods in the past, because they just don't work with the car or setup. Mods need to be an informed decision - they need to be planned and tested!

[@Alexander-bk1se]

Agree on the anti roll bar. Only a few people understand that a stiffer anti roll bar gives less traction on that axle. It's nice to put a stiffer one on the back for more oversteer but still drivers preference. At yhe end the owner said he added the anti roll bars because of the car rolling. The car rolls more because of the lowering springs. If you lower a car and keeping the same spring rate the car will roll more. I am curious if this knowledge known by others. This is how the car manufacturers develop their products. If you lower the car the angles of the mcpherson will increase the distance from the rollcentre and the center of mass. If the rollcentre is equal as the center of mass the car will slide before warning the driver.

[@poligraph666]

[@rogerrubas6260]

Running harnesses on a kbrace is so risky. They’re literally just bolted down using rivnuts. They wouldn’t take the force of the harness pulling them in an impact. Spends all the money on performance and skimps out on safety!

[@Gouranga552]

great driving with the low pressures. i think something to mention is that not everyone will push the car as hard as Misha and it may seem "fine" to them for the driving they do.Given Misha has much more experience than even some who are regulars at the ring. When they ask Misha to drive their car, they are getting one of the best on the ring and their car will suffer the wear and tear of the ring that much more in his hands, this isn't a fault it is just a fact. Misha should not be the person testing the car to its breaking point, you can tell he does everything he can to respect the car and its owner, he's there to drive the car for pleasure not as the guinea pig . I 100% agree with the contract/agreement to be signed, dont need to leave things in questions if something goes wrong.

[@xZiMinDaveyy]

Misha next time take your responsibility and went off halfway of the track, mid exit…. And add some pressure at the ARAL and do again a lap…. Not only for you but the car/ the passagier/ the tires….

[@TheTechnoaddict]

If it was cold pressure it wasn't really 2 low cause they would reach higher pressure pretty fast with some heat in them. Think the understeer was mostly generated by the stiffer arb in the front together with lowering springs without changing the camber. Lowering springs can really have a bad effect on the geometry.

[@CL9k24a3]

Most of people dont play with this stuff so have no idea on how sway bars and chassis bracing affect handling.

[@R56TurboCharged]

Tyres will overheat faster if they are under pressured because there is more movement in them which generates more heat. Correct pressure when cold will give the best contact and performance as FULLY TESTED by the MANUFACTURER.

[@tbrowniscool]

I know it's so fucking stupid putting 24/22 psi in this car. Think he knows more than the manufacturer

[@gldgti]

Dude just wanted an excuse to buy new rims... Seriously though. If he was seeing 10psi increase over the lap, it's because there was so much tyre deformation and so much heat gain. You can start higher and have less tyre deformation and end up at a similar pressure but lower tyre temp. Those poor tyres. I run 18psi in the back tyres of my Ibiza 6k track car... With no interior at 50 series tyres 🤣

[@MrTchou]

With such low pressures you get in a very high risk of the tyre simply blowing up.

[@wk278]

[@bazzmundo]

Misha this is your business you need to have a checklist and a disclaimer/ contract between you and the car owners. You should get a lawyer to check it over first. Please do this to protect yourself and your career.

[@sebdavid]

That's not THAT low. I start off at 1.7bar cold on the M3 and end up around 2.5-2.7 hot. But of course I don't go barreling into the first corner either, I take a little time to warm them up. And Nankang sidewalls are pretty stiff. I think the understeer has more to do with stock suspension with stiffer springs and rollbars, that's what I've found with Bimmers usually.

[@tescolonggrain]

There's so much misinformation in these comments. And surprised by the blanket statement "never go below 30psi" like what? He's on semi slicks, he should be starting at like 26psi or 24psi, he will reach 32psi within 5mins. I run R888R and on my 1050kg car I have to start at 21psi and I will come back in, and after at least 5mins of waiting in traffic in the paddock before I reach my pit location, and check pressures - they are at 30-31psi, that means 33+ "in the moment" on track. Too much still. Road tires are different, but you can still reach 7psi gain during a hot lap. Only soft tires like PS4 are supposed to be running 38psi+ hot and that's to make up for the appalling soft sidewall. Semi slicks are usually 30-31 hot, 20-24 cold. I'm not entirely sure how much this changes when you apply it to a 45,000,000 tonne BMW but for "most" cars in my experience this is the case.

[@LawrenceTimme]

Big difference when the car weights so much more. You car at 1050kg will be fine on 20 odd psi. For a big chungus BMW like this it's not a great idea at all. Should do a lap on a higher pressure then take some out after they've warmed up. If you think about it that car is 60-70% heavier and had a very small side wall.

[@tescolonggrain]

​@@LawrenceTimme big chungus lmao. The guys on AD08Rs which are a borderline semi slick, very close to road tire. He prob shoulda started at 27/28 since the Ring is immediately fast but not very corner intensive for a short while, but even in this video you can see they've come up to near 30psi by the time he reaches the Swedish Cross and then after that I heard no more complaints, and very little tire squeal ...cos they weren't too low for long lol :x

[@elevatedperformance]

The lowest I’ve ran is like 28psi and that was on my z06 which wieghs 3000lbs He ain’t too light either lol gonna destroy his rims It’s not just understeer. It’s also a safety thing. He is compromising the wheel structure.

Money does not buy knowledge that's why accidents happen, let's see we all have mistakes but if you are going to build something with 600hp and not know what tire pressure to use it seems irresponsible and risky for everyone

[@rjac001]

What I learned at a trackday was to start of with normal pressure, then as the tires heat up let some air out to maintain the correct pressure, most guys at the track will have a pressure gauge, then when your finished pump them back up at the nearest gas station

@@RiasGremoryS54 No stock E36 laps the ring in 7.10😂😂😂 An E46 CSL was in another league to any E36 and that only laps in 7.50. A 997, GT3 laps in 7.40 and that's a chassis in another universe compared to the E36 and when we say Laps, there are a few permutations, BTG is generally the trackday guys but manufacturers get a full lap but doesn't include the GP circuit, which makes lap times difficult to compare.

Why would you go through the sacrifice of gutting the rear on a sedan to set up seats, but only install lowering springs instead of actual proper suspension? For the type of tire it is fine to underfill a bit but 22 psi? goes through the PITA to install sway bars on this platform but doesnt do camber plates... 600hp but no LSD

[@slipstream1]

probably should have cruised round for a lap and sorted out the pressures after being advised they were so low, typical hindsight etc (only superlight cars like caterhams run in the 20 psi range typically) that said pushing on and showing the behaviour probably will save some repeating the same mistake but wouldnt want to get involved in an incident on track once you have doubts on a cars track worthiness.

The tire pressure isn’t the main problem here. You can see troughout the lap that the ‘way the car understeers’ remains the same when the tires get up to temperature. I’d guess its a wrong ride height and setup of caster angle 📐 that makes the rear so planted, the front isnt getting the chance to grip properly. Seems like its setup for stability.
