Which M42 engine version is this? You have the late model front timing cover on which allows you to run the more modern alternator and belt assembly. The older timing covers only allow for the older style v-groove belts. OR Did you fabricate a way to mount the newer style pulleys on the older timing cover? 🤔 Either way, this is really cool to see. Can't remember if I've ever seen a running m42 out of the engine bay haha
BMW M42 from 1993 e36 318is. I believe all e36 M42 have serpentine belt. E30 M42 are V-belt. I built the running stand with chassis side engine harness connector. It has switch box for ignition switch and fuel pump. Just need the remote fuel reservoir which is hanging from the ladder.
Stock Water pump, 75C Thermostat. The fancy metal tube is just a tube in tube heat exchanger to take the place of the radiator so I can run and tune the motor for long periods. Engine reaches and maintains normal operating temp. Stock throttle body, and Stock head, porting, and valves. All the "magic" is in the cams, airbox and runner size. 100+ hp/liter. ~200 hp at the crank.
marginal gains. The stock "bundle of snakes" intake (long and small runners) is made for low and mid-range torque. Look at the stock dyno graph, the torque drops off steeply about ~5000 rpm. This is mainly because of the long and small cross section runners.
Custom Intake, stock throttle body, Special small injectors from a new/modern BMW, custom ground cams & solid lifters. In this video, I am tuning the factory ECU = *note, the 282 WOT fuel map cannot be tuned. It is hard coded. I am running and tuning the 175 ECU from e30 which allows tuning changes to the WOT map. I am now switching to a plugNplay LINK standalone ECU for easier tuning and more control, should be more power running Speed-Density (no flow meter). Currently making ~180 hp - we race against 2.5 e30 and e36 and are equal in power.
@@Testa11 Cams and ECU are the big expense items ~$3000 for both. I fabricated the intake = there is nothing like it on the market. Engine makes ~140 lb-ft of torque from 5000 to 7500+ rpm. It is over 200+ hp with 7500 rpm limit. It can rev a lot higher. 8500 rpm would be close to ~226 hp but the injectors run out of duty cycle. Big injectors can rev higher.
Thank you for the comment. The motor makes the same power as the 2.5M50 6 cylinders we race against. I am now switching to a standalone ECU for easier tuning, and to run Speed-Density or AlphaN.
translated = what control valve? I don't understand what you are asking about. Custom cams with solid lifters. Now running Link ECU for BMW e36 for full control
Custom Cams, custom intake, stock throttle body, LINK ECU. Solid lifters and Supertech springs. The head and valves are stock. No porting. Intake is specifically designed and fabricated to match the cams. This yields ~110+ hp/liter
@@kylemcfarlane4274 no oil pump issues. Latest build I shimmed the oil pressure spring for increased pressure at redline for better oil pressure and flow for more bearing protection.
thats gotta be the fastest Hardwood Dolly in america

One fast ladder
What’s the cooling setup for all this extra power ?? Electric water pump, thermostat temperature, etc. ?? Nice clean effective mods ! Love it.

Hey, if I use a lightened flywheel, chip, and change the cam and valves and lifters, what hp would it push roughly?

@BMWontrack Okay, thank you! I didn't know if I'd get any noticeable gain in my drift car with those mods because for a similar price I can turbo it
Yes!!!
Now still tweaking the tune to get the most reliable power
Nice. What’s been done to it ? Cams and tune ?

@@BMWontrack What is the cost of engine parts alone, and how much hp can it handle?

all that work and you still runing on that ancient vane type afm? just get speeduino or something more recent

I did switch to a Standalone ECU running Speed-Density, or Alpha-N. Motor is now making ~200+ hp at the crank, or ~177+ hp at the wheels.
Que comando de válvulas é.
translated = what control valve?
I don't understand what you are asking about.
Custom cams with solid lifters.
Now running Link ECU for BMW e36 for full control
What is the complete setup?

That's amazing. So it's roughly 250hp
@@kylemcfarlane4274 110 hp/liter at 1.8 liters = 198+ HP. actually ~203 hp at the crank
How did the oil pump perform?
