That's a decent time! However that's an absolute insane amount of ignition timing, must be very low compression for that to work at normal AFRs/Lambda values on regular 98ron especially with the high sulfur content like in most eastern countries 🤔 How much were those pistons machined down? I have like 16° less timing than that on regular 98ron at ~1345mg/c top end😅

@@ArturssonEngineering stock piston, T5 but they are from 92-94. So they set it up for me, without the interior it turned out to be 10.95, there is a video in the profile

​@@ArturssonEngineeringAfr values were in range 11,2-11,5. Leaner mixture with lower ignition is next step)

@@agressor9593 This definitely explains the ignition timing as the 92-94 long block pistons lower the compression by quite a bit then adding to that running fairly rich. The b2x5 cylinder heads do have a few CC larger combustion chambers aswell 😄

@@ЕгорПервов-и5я It does a lot of good balancing that out at a lower ignition timing with leaner mixture! Excessive amounts of fuel is the number 1 enemy of the engine. It actually boosts the knock scenario in the end as residual fuel gets trapped. All about finding that balance.

It mostly comes down to personal preference, but I think this FM57 gearing suits wider range of usage and had a very positive effect on fuel consumption! Especially with a car that has higher torque it is more usable as you can stay within the torque curve for longer. Previously on FM55B10 4.05 i had to shift at 160kmh in 3rd gear on the speedometer, now with the FM57B11 3.82 I can shift within 170-175kmh instead

@@ArturssonEngineering Sounds like the difference is there. Thanks!

3rd gear, have a bit longer 3rd gear due to the 3.82 final drive gearbox

@@ArturssonEngineering Is the 3.82 final drive weaker than the 4.05? I thought that I read somewhere that the 4.05 was stronger, but I'm not too sure.

I have experience of tuning G25-660 0.72/0.73 having full go at 3400rpm on petrol so the G25-550 will be even faster spooling. The compressor wheel is kind of weak and has low efficiency in really high rpm. So one has to help them to stay efficient and not have so much restrictions that pushes against it. So take the 0.73 housing, because if tuned properly it will still come alive low 3000rpm🤌 Valve float starts happen at 3.2+bar exhaust manifold pressure on original valve springs at 6000rpm and chokes badly making terrible power while wanting to knock. But 6600-6800rpm is definitely safe in most cases max 1.4-1.5bar boost, not with higher boost levels than that😅

@@ArturssonEngineering and what sort of Nm or HP will it push with said G25 turbo? and ofc the supporting mods needed like a 3.5 inch exhaust minimum

@@rubeneeltink8607 3.5'' exhaust and adequate tuning I see no issues in making a decent 500bhp/650nm, maybe more if the scenario is truly optimal! Hard to tell at current moment!

E85 can be very very tough on engines. Especially when tuned rich and inefficient, not sufficient ignition timing which everyone does and just cranks up the boost pressure for no good. Engine worn out in no time.

Exactly that, the petrol has higher initial cylinder fillage due to a lot less disturbance of the intake port flow. E85 has more mass taking space and tries to be atomised disturbing the airflow. So petrol spools slightly faster and most often has even slightly higher torque output or similar to the E85 depends on a lot of factors. Energy density and more intial flow. The low end is really nice and more responsive on petrol while also having a much more stable power curve up top which only drops like 5-8bhp when running past the cams efficient range. E85 is only good on the top end up until it starts choking slightly and then immediately looses 30-60hp as the flow starts to struggle because of exhaust mass. This is why im more and more oriented to running petrol nowadays, I dont see the purpose of E85 personally

@@ArturssonEngineering Well, with those kind of results e85 is quite pointless. Only point would be the psycological lower filling price! 😂

​@@J1I9M7M4YPretty much it 😅 Low load on E85 is rubbish aswell 😂

The 400nm is only the transmission case rating in terms of earliest stage it may start to flex and nothing else. It is a underrated torque number to keep them safe in all conditions. The gear sets have tremendous strength and the tripod design of having 3 axles stabilising the whole thing makes it even more capable of withstanding flex. Always being stable and no misalignment with the gear teeth as things starts to flex. It is like the F35 transmission casing is rated to even lower numbers, but the gear set alone is rated to max 700nm. But its down fall is the two axle design which doesnt help the casing withstand torsional flex. The gear set of the F40 even higher, saab engine lab used to run 700-750nm through these F40s in various projects. My sources are former Saab/GM drivetrain/engine lab employees. Also in relation to what I have noticed myself how strong they are with the correct treatment of proper tuning and sensible driving.

@ArturssonEngineering Thank you for time answering.

This is tuning done by me

@@ArturssonEngineering nice,would love to have more power in my 9-.5 but i cant afford it,and well maby a day my dream come true.. u really have a angry 9-5 there...

100-150km på ca 5 sek och 100-200km/h ca 10 sek mätarfart. Det är inga 600hk i denna bilen. Så tunga är dom inte . Välkommen så kan vi köra den i bromsbänken nån dag så slipper ni fara med osanning

the wagons are a hell of a lot heaveir than the sedans, probably part of it

acceleration has nothing to do with horsepower.... you can have 150 hp and 700 in torque, or 700 hp and 200 in torque

Stämmer det, inställningar jag provat fram specifikt för min, fungerar möjligen inte på annan med mindre modifikationer osv

I went to these as the NS2R didnt perform at the level I wanted. But it is a decent in-expensive entry level tire. Whenever in slightest wet or the tire is a bit too warm they spun immediately even in 3rd gear for me

Unfortunately there are too many clueless people out there with nothing but opinions and very little sense for basic physics.. I find it quite funny when people with 700hp rwd cars spin their wheels in severals gears and legit struggling. It is not that hard to get it to hook even with a FWD as previously show with my old 700+hp car.

The SMP 846cc have better allrounds function in all RPMs and different fuels, these Bosch ev14 870cc I strongly dislike in low load on petrol/gasoline for example. On E85 with longer opening time they work better. The spray pattern is a bit too wide and too fine so the high pressure spray mist actually wants to clinch to the port walls in low rpm and even partially on low midrange. So there is a jump in 50-60nm for me in 3700-4500rpm. But great efficiency rpms above that! The SMP 846cc has basically extremely minimal wall wetting with fuel so they work everywhere and make the car responsive and fuel efficient everywhere. I would say in most scenarios the Smp 846cc are still top dog 😅

Only 205/55r16 tires and open differential. About 600nm and still no wheel spin. Good tires and wheel angles is what matters, narrower tire width increases contact pressure for acceleration aswell. But there is this balancing act ofc. Like I have managed to get 700hp to hook with full traction on 235 width, it is not that hard even on a fwd, all about balancing the car

FM57B11 transmission instead of the FM55B10 so I get the longer 3.82:1 final drive which affects all gears

No and the catalytic converter will be destroyed

Because the launch control, it is a controlled misfire on purpose so its giving a false signal
