Perfect oversteer characteristics, delicious engine in the high RPM’s that you should use it in. The rise to that area is still reasonably smooth, but you are really missing out if you don’t keep the rpm high.
Under 125k price, under 1000 kg weight and between 300-330hp in the rpm range where the engine is hanging out when going through the gears
I am quite satisfied with the car overall, I assume that is decent stats for its cost and car type considering the year restrictions (I also stayed away from the quality slider)
But! there is one issue
I always make sport engines that are very thirsty, I will gladly take tips on how to tune the six to make it more fuel efficient without making it to tame for my “supercar on a budget”
Okay here’s my tune of your engine, it’s down a bit in power but up in reliability and economy. I played around with the gearbox and downforce a bit and found that for about .1 in the quarter mile this will return 13.19l/100km, and keep your 3.5 0-100kph and standing km time.
Nice, tuning there. (I actually played around with the downforce before you posted )
What is you initaial stategy when trying to tune a turbo? That is sort of a bit of dark art for me.
Do you have any other feedback about the design anything in general you think is well executed, or are there some other glaring issues?
Your cam was way too high for a turbo car, first thing I did was lower the boost and timing and start decreasing the cam, that was the biggest economy gain, your max power was actually around 80 or so, that’s why your torque curve was so messy, your turbo spooled up before your cam so you hit boost then your cam got into it’s power band. I actually saw about 370hp with the proper cam setting before bringing it down.
As for the car, setting your front brake pads to 0 was hurting you, put them to 40 or 50 then decrease the rotor size to just enough to not incur a brake fade penalty, the rears were okay at 0, flaring the fenders out a bit more allows 205mm wheel width which helps you with grip. here are a few screen shots for the tabs.
Ah so it was the fenders that were stopping me from getting wider tiers, I did not understand what was stopping me I though they were a bit narrow for a 90s car.
And thanks for the cam tip to, I have been doing that to my NA hot engines and i didn’t fully understand the implications when going to the turbo.
It’s a good car you have there, although I don’t think it’s in the same class as an M3 seeing how in the 80’s and early 90’s they only had a 240-260hp N/A 4 cylinder. were you maybe thinking of the M1?
Haha that would be a closer fit
When I first started doing it, it was styled after the E30 m3 visually when i first built it, and the initial Idea was to sort of build it but with the engine monted transverse in the mid. But then I got carried away
Tbh it was sort of something I would like to see done irl.
Imagine something like an Elise but with a transverse inline 6 smacked up against your back (For a good example of a sporty transverse inline six install, look no further than the polestar s60)
Engine and drive train:
Volvo T6 inline six (B6304T4)
508 hp @ 6500rpm
575Nm @ 5500rpm
Max rpm: 7100
Modified cylinder head and combustion chambers
Modified inlet manifold and air intake
Special manufactured conrods
Garret 3171 turbo
Ferrita 3.5" stainless steel exhaust system
Reinforced M66C (close ratio) manual 6-speed gear box
Haldex E-LSD in rear
Haldex Gen4 XWD
Unfortunately I doubt I would ever be capable of fitting that properly in automation, but if you ask me such an install (with a less race tuned engine) would make for a damn fine mid level sports car!
