Player's M20 B28 with dbilas inlet and 6 branch etc is doing 260bhp, i'd guess that lot would see you with at least 10 bags in the engine once it's mapped etc
How did you manage to get 265bhp out of your B31?reggid wrote:Was 'only' 226bhp!
Dbilas:looks nice but doesn't do much, it is still only an off the shelf part. Is better to have a system that is designed to work with everything else

Bmw got 320hp out of the group 2 e21 323i, kolb motorsport in Germany do a 300bhp m20. Tuning engines has not changed since the 1920's when Sir Henry Ricardo wrote the book.
It's just a big HP m20 is going to cost as you would have tyo pay some one like Owen to do the r&D dyno time and make the parts

To be fair though, tuning for racing is easier than for a road car as race engines don't need any power at all below around 4000rpm. Tuning an engine for road use while keeping it tractable and generally useable is more tricky. Look at F1 for example. 1500bhp from 1500cc's, or 1000bhp/litre. On a road car anything above 150bhp or so/litre is an achievement.e21Jason wrote:Bmw got 320hp out of the group 2 e21 323i

The DBILAS is not as much gain as many think..
bolt on ,,, the power is minimal,, you have to tune in the ECU and so on,,
if you use a sporty camshaft,, performance headers,, good exhaust system ,, higher FUEL-pressure and so on you are maby seeing 220 ps..
oem M20B25 airflowmeter can just make 240 ps as far as i know, but with M30 airflowmeter ,, you can go further
i am facinated about the M20 ITB solution but to get real horsepower,, the engine must be well tuned ,,
i have heard of a M20B28 in Germany that has a lot of extras and output is 260 ps with high cost .. but the engine is really pulling

that 226 is at the wheels, crank measurements are very different.
if you want a quantitative measure of the engine, do it at the crank
if you want to know how much gets to the road then do it at the wheels.
better if you know both.

Just checked my old magazine articles and I was a bit they only got 290bhp out of the 2.3 m20 in 1982, Hartge built engine based on the work done for the 323i rally cars which won there class in the European rally championship.
The engines were built for Alessandro Fracastoro for his European Mountain Race group 5 e21 which took one first place and one second that season
Off course m20 race engines lasted one event, ran race full and were very peaky back in 82

290bhp from a 2.3L 12V M20 is an aweful lot, would need to be spinning 9000rpm+ to make those numberse21Jason wrote:Just checked my old magazine articles and I was a bit they only got 290bhp out of the 2.3 m20 in 1982, Hartge built engine based on the work done for the 323i rally cars which won there class in the European rally championship.
