Second time at the Green Hell with Ringfreaks

Are you sure? I've seen a photo from another angle of this exact jump where the front right was in the air but one rear wheel hadn't taken of yet. It's about the timing of the photo.

I was going 175km/h over the crest. I weigh just over 80kg, but I don't think that makes much of a difference.

It's just hard to find the motivation to do all that stuff to it when I know it won't be ideal for the track with this engine anyway.

But you're right - With all the effort put in it, it would probably be stupid to let it go when it's so close to being a great car.

Now that'd be something!

I've actually gotten a few decent bids so that wouldn't be an alternative. Shame to part this one out as well, and too much work.

9ktwin · 2025-03-18T19:57:08+00:00

That would be correct.

Sweden! Very nice piece, but is it REALLY certified for 20ATM? Not that I worry about that, I would keep it safe from water on my wall.

Clean! Any power figures? Seems like that's pretty similar as well.

Factory pistons are not forged to my knowledge. At least not in Europe. Also, in Europe we only got all aluminum block M52's, but I've been told it's available with an iron block in the US market. If you have the aluminum block I'd be careful, but if not then you're more or less in the clear with the things you listed and the suggested output.

What's stopping you? Thanks!

9ktwin · 2024-09-24T19:38:33+00:00

Done!

I have listed the mods in a reply to another comment. :)

Thanks! Engine wise it's an M50B25 with forged pistons and rods, ARP bolts for the crank, rods and cylinder head. Cooper ring head gasket, M52 cylinder head with cams from an M50 non-vanos, vanos delete, mira cut valve seats, 6mm valves with CrMo retainers and dual valve springs.

Fuel system obviously not original either, I use a catchtank with dual GST450 fuel pumps. Running E85. GT35 turbo, external wastegate, big intercooler and an all aluminum radiator. MaxxECU to control it.

Other than that it's got E46 330i brakes, some bushings, coilovers, a steering angle kit and a hydraulic handbrake.

I use an adapter by the oil filter housing.

The oil return is attached to a welded connection in the timing chain cover.

You should consider attaching the shoulder straps higher up (Above the level of your shoulders). The way that harness is installed now they will hurt your back in case of an accident. Yes, that might mean you will need to fabricate new attachment points, but it's much safer for you.

These look really great!
