If youre talking about the 1986 cars in specific the main problem is that the cars run 3-5 bars of boost and to get turbo to spool up especially with the BMW cars means the turbo takes anywhere from 1-2 seconds to spool up. The senna throttle blip works midcorner to keep the pressure up as the engine goes from 300hp to 900hp in 1-2 seconds and that burns up the rear tires. Based on my own driving experience the car does indeed mimic how it would be in 1980s. the difference is that nowadays they can electronically spool the turbo with batteries to eliminate most of the turbolag but in 1980s the turbo would take time to accelerate since at first you have low amount of exhaust gas spinning it and it would accelerate slowly. but the more it spins the more boost it feeds to engine and it creates more exhaust gas meaning it starts to spin even faster and its a runaway reaction as more gases mean faster turbo and faster turbo means more boost what increases the gasses. but this also means with cars like BMW on the 1986 mod is that you have to apply the throttle at the apex so the turbo is working at the exit of a corner. If your engine is overboosting above the set limit that you have. you have to assign these values to it. Wastegate=(-5000,0,23500,1.0) // minimum relative boost pressure (to desired), minimum wastegate opening, max relative pressure, max opening So here the minimum relative pressure is -5000 or -0.5 bars, then the minimum waste gate opens at 0 pressure, the max pressure it goes to is 23500 or 2.35 bars and its max opening is 1.0 so it bleeds off all the gasses from that. this means the turbo boost stabilises at the max boost level. the car has since the waste gate will open at 2.35bars. This also means that even if i run similar turbo to the 1986 mod instead of the turbo going 90-130k mine does only around 75-90k BoostTurboPressure=(182500,10000) is set to be higher than that it means the engine will boost higher. its 1.825 bars and it has 6 settings on it. so its 1.925, 2.025,2.125,2.225,2.325 so the last boost level useable peaks at that value. i do have push to pass that goes to 2.525 Bars. so the max wastegate max relative pressure needs to be somewhat close to the max boost turbo pressure. If you want to tweak the turbo curve response you need to tweak the TurboInertia=2.8e-4 TurboFriction=(0.55,0) TurboStaticFrictionWatts=1350 All these values indiviually. and when you got them. you need to tweak them Here is a turbo that spools up at 7000rpm TurboInertia=2.8e-4 TurboFriction=(0.55,0) TurboStaticFrictionWatts=1350 TurbineFlowTable=(0,0.060722) TurbineFlowEffects=(1,0) TurbineFlowEffects=(1.2,0.05) TurbineFlowEffects=(1.4,0.12) TurbineFlowEffects=(1.6,0.2) TurbineFlowEffects=(1.8,0.35) TurbineFlowEffects=(2,0.5) TurbineFlowEffects=(2.2,0.61) TurbineFlowEffects=(2.4,0.7) TurbineFlowEffects=(2.6,0.77) TurbineFlowEffects=(2.8,0.81) TurbineFlowEffects=(3,0.83) TurbineFlowEffects=(3.2,0.835) TurbineFlowEffects=(3.4,0.83) TurbineFlowEffects=(3.6,0.82) TurbineFlowEffects=(3.8,0.81) TurbineFlowEffects=(4,0.785) TurbineFlowEffects=(4.2,0.765) TurbineFlowEffects=(4.4,0.73) TurbineFlowEffects=(4.6,0.71) TurbineFlowEffects=(4.8,0.67) TurbineFlowEffects=(5,0.64) TurbineFlowEffects=(5.2,0.63) TurbineFlowEffects=(5.4,0.62) TurbineFlowEffects=(5.6,0.61) TurbineFlowEffects=(5.8,0.58) TurbineFlowEffects=(6,0.52) TurbineFlowEffects=(6.2,0.48) TurbineFlowEffects=(6.4,0.32) TurbineFlowEffects=(6.6,0.26) TurbineFlowEffects=(6.8,0.2) TurbineFlowEffects=(7,0.1) To determine when the turbo starts to spool up and when it stops to spool up. It will require quite alot of trial and error to do that since the second value determines how easily the turbine spins. so if you increase the lower values to be higher the turbo spools up easier. TurboInertia=1.9e-4 TurboFriction=(0.25,0) TurboStaticFrictionWatts=750 TurbineFlowTable=(0,0.089722) TurbineFlowEffects=(1,0) TurbineFlowEffects=(1.2,0.61) TurbineFlowEffects=(1.4,0.65) TurbineFlowEffects=(1.6,0.65) TurbineFlowEffects=(1.8,0.65) TurbineFlowEffects=(2,0.74) TurbineFlowEffects=(2.2,0.71) TurbineFlowEffects=(2.4,0.78) TurbineFlowEffects=(2.6,0.74) TurbineFlowEffects=(2.8,0.78) TurbineFlowEffects=(3,0.8) TurbineFlowEffects=(3.2,0.81) TurbineFlowEffects=(3.4,0.805) TurbineFlowEffects=(3.6,0.79) TurbineFlowEffects=(3.8,0.77) TurbineFlowEffects=(4,0.74) TurbineFlowEffects=(4.2,0.71) TurbineFlowEffects=(4.4,0.68) TurbineFlowEffects=(4.6,0.65) TurbineFlowEffects=(4.8,0.61) TurbineFlowEffects=(5,0.57) TurbineFlowEffects=(5.2,0.53) TurbineFlowEffects=(5.4,0.48) TurbineFlowEffects=(5.6,0.43) TurbineFlowEffects=(5.8,0.38) TurbineFlowEffects=(6,0.32) TurbineFlowEffects=(6.2,0.28) TurbineFlowEffects=(6.4,0.22) TurbineFlowEffects=(6.6,0.16) TurbineFlowEffects=(6.8,0.12) TurbineFlowEffects=(7,0.1) Here is turbo that spools up at 5500rpm So these values should get you started on tweaking the turbo. keep in mind you also have to tweak the compressor too to optimise it too.

Hi @trollray and @doddynco How is the progress on the mod? dont worry we have not forgotten about you two. just asking about progress so if you can tell if you have been doing anything for the mod it would be nice to hear
Hi mate thank you for asking. I'm just taking a break on the project over the summer as I don't really like being at my computer much during the warm weather. I'll be back in the late autumn/winter with the intention of finishing the project in that push. All the best for now and expect to see the big releases around the end of the year.
Does anyone know how to fix 1986 turbo issue? All three 1986 mods have broken turbos Only the recent one that has only Brabham, Benetton and McLaren have no issues with turbos
It is not functioning. 1/6 and 6/6 result in the same power. And that power is sufficient only for 140mph
Hello, if you talk about the other mods, we did'nt work on them now so only the HE edition is in our plans. I still stay aware of bugs for 1988 season but for 1986 you have to wait till @doddynco finish the rest of the cars. Turbos and sound have problems for many older mods since updates from s397. Don't know why. So , be patient for the HE
0.44.2 All cars updated to v1.18 - Fix tyre air cooling issue - Added titanium skid plate underbody protrusion - Adjusted spring rate ranges and defaults 0.44.3 - Suspension geometry tweaks to Benetton v1.18.1 0.44.4 - Fixed Benetton spring rate selection error v1.18.2 0.44.7 - Fix UI images 0.44.8 - Tyre improvements - McLaren default setup tweaked for new tyres
New update today and a new car is released. Me and Trollray have been talking a lot about tyres lately. I feel as though we have been generally moving in the right direction. It's tricky to get perfect as your perception tends to gets warped the more your are exposed to them and a sanity check is necessary sometimes. We would be interested to know your thoughts on the tyre behaviour - grip levels/speed, feel, heating, balance front/rear. https://steamcommunity.com/sharedfiles/filedetails/?id=2295224315 0.45 - Added new vehicle: Osella FA1-H - All vehicles updated to v1.2 - Tyre slip and deflection improvements - Benetton updated - diffuser ground clearance sensitivity reduced, wings rebalanced, dampers tuned - Fixed correct compounds not showing visually on Brabham and Mclaren - Fixed missing Mclaren low rev sound Known Bugs: missing turbo sounds (RF2 Error- affects all mods/content)
Ah yes the rarely heard V8 Alfa turboengine. this is functionally the second instance i know that its being heard anywhere. since seemingly it was too hard for most people to find a recording of it in the past so they slammed a V6 sound to it. The problem is that there is exactly one clip around that has tolerable audio so its lucky we have it at all! Good work! its as much of a shitbox as i would have expected osella to be! and by that i mean that its slow and has no grip since the only way it qualified was that there was not enough cars to cause people being nonqualifiers so they only non qualified on monaco LUL
Thanks for another "impossible to drive car". No, mean it in a good way. Gone try it tonight. If there are tips for setup, or for any of the other cars, please reveal.
1 2 Keke Rosberg McLaren-TAG 1:42.478 1:42.013 — 25 21 Piercarlo Ghinzani Osella-Alfa Romeo 1:56.468 +14.455 26 22 Allen Berg Osella-Alfa Romeo 1:56.959 +14.946 You know when this happens in qualifying at 1986 hockenheim you know its a shitbox! LUL I mean its a 1983 alfaromeo without really any updates in 1986. the results are pretty expected for not doing any cardevelopment for 3 years...
Well the default 'GP' setups tend towards less aero than is perhaps desirable. The teams would run the fuel-limited races like this because they needed to make the cars as efficient as possible. So if you just want to get a feel for the cars I would suggest max aero, or maybe trim less front wing than max to introduce a slight high speed understeer depending on how you want the balance of the car. Also I would run with half a tank of fuel. There is something like 200kg of fuel on board, the default setups are designed for a sweetspot (in terms of car balance) at around half a tank. If you're always on edge with the car, softening the rear roll bar will just tilt the balance towards understeer, but don't rely too much on making the car understeer in order for it to become easier to drive because when the back end does fling round (and it will fling round) having 180 degrees of steering input as you slide the fronts is going to cause very fast spins which are difficult to react to. Whereas if the car balance is neutral, you can dance the car around the center of the steering range, with good throttle inputs. Max front and rear downforce will probably be quite demanding to drive but with throttle discipline and anticipation of countersteer (from getting used to the turbo behaviour) you should get pretty used to it. I hope you like the changes in the new update, - there is more overall grip, however the rear tyres are also slightly stiffer which has moved the mechanical grip balance forwards. The update I would say improves the feel of the cars a lot but it also demands more throttle modulation. The old rear tyres were not achieving a proper slip angle, and therefore the cars were not rotating on throttle under normal driving - it was only when the rear completely lost grip did the cars actually spin.
Hi all. as another gift, i have tested some new approach for the 1988 cars. The update is also uploaded now !.(3.04) I'm pretty happy with the way it feels but thanks in advance for your feedback, that will help both of our 2 season The Ai is also rebalanced and seems to work very well in my own tests. That said, as @doddynco said to me in our late night discussions, think that the cars from 1986 and 1988 are brutal beasts and generally, the rear control is about right foot discipline. Some drivers are too modern and forget that traction control where not an option in the 80's. So a car of 600 kg with about 1400 hP and a turbo lag would be a peice of art to drive. same for 1988 but in a subtle evolution. I can promise that when you understand the technique, this is a blast to drive! And you will have a lot of respect for all those drivers of this era. (I died virtually so many times lol) Thanks for your feedback and to my Friend @doddynco for his hard hard work every night Cheers and have fun with wathever shitbox you choose to drive tonight
