E28 Dyno Database

[12valves]

This is my 633CSi, stock engine with Megasquirt and AFM delete. It made 163hp and 184ft*lbs at the wheels. It's a different dyno than the one I used for the M20, but the same one I used for the M10. Looks like the M10 was a bit more efficient at low and high RPM due to the 9.9:1 pistons I had in there, but the M30 wins the midrange on account of its higher valve lift.

update: more info

• Freshly built M30B35 with 92 miles on it
• 10:1 Compression
• Paul Burke N12 cam
• Stock 179 ECU
• AFM
• Bav auto headers
• IE exhaust

Here's a video of the 3rd run, showing just the tach and wideband, this was the best run:


Here's the final run from a different perspective :-):


Here's the graph, which includes the two best runs done with the B34. Note that it was about 82 degrees today vs. 70 when I did the previous run (and those B34 runs were in 3rd gear).

Latest results, now with Miller WAR chip; tuned.

Hello from Finland.!

Here's my dyno paper. (Sorry about crappy picture)



Alpina B6 (m30b28) engine (fully rebuild)
Holset Hx35 turbo,525cc injectors,Vems V3 ecu,etc...
@1.2bar pressure with E98 fuel.

That's the limit for that turbo and injectors.
Injectors are ~98% open and Holset is 57/60mm #12 exhaust housing.
After that just exhaust pressure start to climb over boost,so that 423hp/573nm was were we stayed.

I have bought already bigger injectors 1600cc and Masterpower turbo. (61/64mm #17 exhaust housing)

Maybe next season i also move to Re85 fuel.

Next summer well see how these modifications will work.

That thing is flat. Impressive. How does it drive?

[athayer187]

It drives awesome. I've only been able to drive it in the wet so far, but just stepping on it on the highway brought a smile to my face!

Popped off the head, got a valve job done, shaved .010" and put in a B35 cam. (piston-to-valve clearance looked to be about .09" intake and .11" exhaust.) Also converted to wasted spark.


Gained some torque over last time. 168whp/191 now vs. 163whp/184 before. It still pretty much gives up after 5000rpm. Weird.

Look at how much lower the blue line is. That was the first run, and the only thing different about it was that the engine had lost a little heat while cars were being rotated onto the dyno.

The lag is intentional to keep clutch/axles/gears alive

460/460

13psi to 16psi to keep hp up but... the m30 intake is what it is and dies at higher RPM.

hx40 (58mm),

e85.

maxed injectors
maxed pump
maxed turbo
maxed cam :P

The results.


145whp/163wtq

[tschultz]

Charlie, time to bump that one up with a low boost turbo now that you have all the other pieces in place for it!

[Shadow]

hey i re-dynoed with new ie valve springs.

if you go back and look at allot of dynos they fall on their faces alittle past 5.5k.

it's valve float. get valve springs.

480t.450h

he loaded it more on the dyno and it made 500t @ 3.5k.

Lower hp and torque run is with the stock euro 061 DME and the higher one is swapping my tune in

I believe we are at Stock B34 cylinder head limits.

Mods:
Schrick 284
IE Headers into 2.5 exhaust w/ old old magnaflow
Euro Piano Top Pistons (10:1)
My own Eprom (tuned Miller WAR and converted to 2732 chip) on a 059 DME
M5 Flywheel

Stock B34:
Injectors
Intake Manifold
Valves
Throttle Body

Bascially a euro b34 with a cam, tune and headers

TCD Stage 2, Megasquirt w/ wasted spark. M30B35 w/ARP head studs otherwise stock internals. 255lph fuel pump, 60lb injectors.
