M52 hp?

[mtlbloodshot]

Trying to find out how much HP a M52 will make in a E30 with some minor mods. Rough estimation. Can someone help me?

- M52
- 21.5 LBS/HR INJECTORS
- S52 CAMS
- ODB1 (intake manifold / MAF / fuel rail )
- TRM TUNE
- Stock M52 HEADERS

from what ive seen its usually 200-210 but id be interested to see dyno charts and actual number.

They mention that just with S50 OR S52 cams (assuming a tune) will provide 200 WHP.

I dunno how much or if the the odb1 conversion adds any power.

I have this exact setup and have read it should be somewhere around 210-220 whp. I haven't dyno'ed mine yet so I don't know the exact number I'm getting.

The obd-1 manifold is good for 15-20 peak hp, at the loss of low end torque.

with those numbers it seems like a great alternative to the s50/52 considering the m52 is generally half the price.

I dynoed 194 hp and 177 ft lbs with everything you listed above except stock m52 cams. My friend with his e36 328is and same exact setup listed above, made 217 whp with s52 cams

[emmanuel.dlc]

mine did 210whp with bad tune, aiming for 230+ when properly tuned.

So if the average is between 210-220 WHP.. What would that translate into it HP?
I read that from the crank there is a average 18-25 % loss to the wheels with a RWD.

crank would be 250-260, but bhp is a pretty meaningless number
