Totally different experience from the ‘club sport’ spec clio to the full on e46. Rear wheel drive is so much more engaging and rewarding but a much bigger challenge. Clio feels nippier due to the shorter wheel base but the e46 is much more planted and the grip is next level. Compared to the laps I was doing in the clio vs the current e46 laps there’s about 10 seconds a lap in it around Oulton Park but my driving has improved some what too. If I had to pick, I’d always have the e46. But have another clio for the weekends again.

I’m actually 30 minutes from Oulton Park despite seeming to spent a lot of track time at Cadwell! Good to see more and different e46’s around. 👌🏼

Custom logger based on Arduino/Teensy logger to collect data from Canbus. Then edited in Race Render.

Cheers! Yeah, Exhaust Gas Oxygen sensor from ECU. Not quite driver EGO! No longer needed on the data now as it’s changed to a STFT rather than instant fueling corrections.

@@Just_A_330ci nice, you have done everything you could to it at this point for reliability 🤞 how’s it feel?

Wasn’t sure it was going to be saved initially!

Even with a baffle it does drop here and there. Improving the baffle design would be a benefit. At least the ‘lower’ oil pressure is when the engine isn’t under load.

Snapped the oil pump shaft it’s self. Needs new bearings and a bottom end rebuild along with a few other damaged bits I’ve found so far.

@@Just_A_330cihave you tried the tensioner mod for m52/m54 with the pump nut mod or was the engine stock ?

@@joseverdejo9010 This engine has the oil pump tensioner fitted. I was hoping it was going to be the fix as it’s been reliable for a couple of years now.

@@Just_A_330ci I was hoping it would be the fix as well, with the tensioner taking slack out of the chain and the nut tied on I’m really curious why the shaft still snapped

@@Just_A_330ci oh yeah they snap shafts too, the facelift engines have an updated harmonic balancer which helps with vibrations

The cams make a big different to the engine, previously it was out of revs at 5,500 but now revs nicely to 6,800. If you've seen the build threads online there a plenty of dyno graphs on there for comparisons.

Initially reading it off the Canbus on the standard ECU. Now I log all the data through a Canbus logger through the ECU Master Black. Same principle just different ECU.

Thanks for the reply. Sorry I'm an amatuer at these kind of things but in my e46 m3 I'm seeing the standard oil temp gauge rise to 3/4s of the way round on track, is this normal as I back off and cool down once it reaches those temps and do you know how accurate the standard gauge is to the electronic readings you're getting as I've heard it reads high.

Would defo recommend doing something! I’ve had 2 failures, upgraded the standard shaft… VAC motorsport kit came loose. VAC motorsport kid lock wired just chewed the shaft and the gear. Back on standard shaft and nut with double lock wire.

Still on the AR1’s. Maybe got one more day left in them now.

This is m50 inlet with Schrick Cams. S50 exhaust manifolds on ECU Master Black.

@@Just_A_330ci Did you ported headed the engine for the m50 intake? I what some Schrick Cams too but theyre expensive as fock 🤣

@@JoeAhmedx Just had a good watch! Should have stayed out longer in front but had been out a while and it was the passengers first time in a car on a circuit as a passenger! 👍🏼

Cheers! Glad you’re enjoying it, check out the build threads if you’ve not seen them.

That’s possible on some dyno’s. But not on this one.
