I have both. hmm ,not sure well they get about 260hp with a m50 intake manifold so maybe guess in the 20hp more again ? but maybe with cams and rev higher might see more google it Edited November 26, 2020 by BM WORLD Quote Share this post Link to post Share on other sites

wrs 120 Report post Posted January 8, 2021 If you put M3 Evo headers, M3 Evo full exhaust, Link ECU and bored throttle body on it you should get over 300 from it. Got 298hp/220kW/344Nm from my M50B30 with this configuration, M52B32 might get more. If nobody wants it I'd be interested in the M Power cover!!

Bandit 194 Report post Posted January 8, 2021 (edited) In a workshop not far from us sits a bored and stroked M20B25 bored and stroked to 3.1 litres and looking resplendent with a set of RHD ITB's from across the Tasman...............hmmm, the problem is no car to put it in (at the mo)😟 The M Power covers are widely available off shore guys about $300 back here last time we looked. 3pedals we think your assessment of this unit is more than a little harsh. It is an S engine and remember its torque not HP that wins races😁 Edited January 8, 2021 by Bandit 1 Quote Share this post Link to post Share on other sites
leichtbau 525 Report post Posted January 9, 2021 I didn't realise Alpina was actually a ship manufacturer, that must explain why the motor was the basis for their E4 / E5 range of engines. 1 Quote Share this post Link to post Share on other sites
M3AN 4016 Report post Posted January 9, 2021 The S50B32US is the best M50 engine ever produced by BMW. It is amazing though that it was only 240hp and the N52, with admittedly a 20 year development curve, produced an easy 260hp with 200cc less capacity. 1 1 Quote Share this post Link to post Share on other sites
Bandit 194 Report post Posted January 9, 2021 5 hours ago, 3pedals said: Another myth - If it were true all race engines would be diesel dynamic power delivery and getting it to the ground in a well tuned chassis pedalled by a talented pilot is what wins races. We used to beat 6 litre v8's in a 2 litre alfa all the time - they had nearly twice the torque we had but the alfa could get it's wheezy 150kw and 240Nm to the ground a lot more of the time. And its not really an "S" engine - it's a bored 2.8 boat anchor stroked to make barely acceptable power to be worthy of putting in an "M" car . I think the entry point into this is "almost" sensible and as we have suggested a set of ITBs, linkages and complete with the lovely carbon fibre air box RHD produce it would produce the goods and a torque curve to match, after a spot of remapping. Its a good chance for someone to build a reliable engine at reasonable cost. Our American cousins love them, especially with FI now that's another ball game 3pedals........😉 1 Quote Share this post Link to post Share on other sites
Bandit 194 Report post Posted January 9, 2021 12 hours ago, 3pedals said: Yeah, my 25 year old single vanos 2.8 M52 with no internal work was last dyno'd at 168kW and 305Nm , with the same Individual throttle body addition it should see another 12kW to 15kW acording to Rama at RHD so 180kW+ . Clearly the cast iron boat anchor that weighs 40kg more and is 400cc bigger in capacity is a superior engine - Superior in holding power for a boat. At the risk of appearing a pedant, wiki motors reveals the weight of the engines we are discussing as being: S52B32 141 kg, M52B28 163kg and the common garden variety M54B30 as 163kg. We have left a hair on the table 3pedals.😉 1 1 Quote Share this post Link to post Share on other sites

The S50B32US didn't have ITB's, I have misinterpreted your post if that's not what you were referring to. But another good example of why it's inferior to the proper S50.

But another good example of why it's inferior to the proper S50. Really Dave read what's posted I'm suggesting here that with a nice set of ITBs and a Carbon fibre airbox as produced by RHD in our own back yard this engine is surely worthy of consideration.
