Just dynoed my m30b35... not pleased.

[bumpstop335i]

I know, I have seen the light.

[george graves]

its an engine design from the eff'ing sixties, what do you expect?

Rolling eyes - oh man - newbi with lots to learn...

[george graves]

May I offer my 2-cents of advice?

M30's are *not* about pure HP numbers (espically in a e30) - It's all about the feeling of getting thrown you back in the seat. It's the TQ that makes it an awesome combination to a e30.

You'd have to drive one to know it...few have.

Remember guys - HP makes you a F1 car, TQ makes you leave the traffic in the dust at the stop light.

A M30 is NOT a S14, nope! And its not just a bigger m20 - wrong again!

It is a m30. Legenday in the BMW world (just ask an oldtimer). Smooth reving, big inline six. Tq curve that looks like a picnic table, and plenty of Hp to boot(or boost...LOL)

300k mile motor(if not more), tons and tons of TQ - and is very happy getting redlined all day long. I'm sorry? But, can you ask for more?

Again, I've had a e30m30 longer than anyone I know on any fourm - so maybe that add a bit of weight to my advice. But my 2 cents anyways...


HTH...

Hey, I'm new here, but not new to the M30. I have a M30B35 (I drive an E34) with a MAF conversion. My dyno results were 196whp/218whtq. Dyno graph is http://forums.bimmerforums.com/forum...d.php?t=686399 Anyways, I thought you might find it helpful and I'll be lurking around the boards to see what other knowledge I can soak up.

I use 'Super' 98 octane fuel, which I believe is the equivalent to 93RON. I'm sure that helps a little :D

One good thing about Lebanon, all they have is 95 and 98 LOL.

[bumpstop335i]

What grade of octane are you using?

Got to hear that it is alive!

[Mike325]

Good too hear man. Let us know what you run this time.

[MrK]

Air filter, fuel filter, o2 sensor...plenty could be wrong.

I'd start by dynoing again with A/F readings. I think doing without is useless anyways.

I don't have the luxury of dynoing with A/F readings. I was lucky enough to find any sort of dyno at all in this country LOL.

Update:

I have an SMT-7 piggyback installed in this car, but I hadn't really touched it until a couple days ago. Using the datalog feature, me and a friend of mine compared +2, +4, +6 etc degree ignition advance. Surprisingly, the beast took up 8 degrees advance over stock with no issues. It also took 10 degrees, but that caused a performance decrease. In combination with richening the mixture slightly after 4.8k rpm, the car has gained some serious pep. Time to re-dyno!

With or without a bridge?

2 ramps....

[StereoInstaller1]

i like tracks that look like 8

[e34john]

[blueapplesoda]

That is what I'm trying to make clear. Is it a 1/4 mile drag strip or a track? Because tracks average 2 - 4 miles in length, and they loop.

I agree.
to some people, track means this: |

imho thats not really a track........i call that a strip...i.e., litmus strip, strip pole, Listerine strips, etc.. they are striaght
in my mind, a track looks like this: S
so whatever floats your boats

[Jean]

lol, i think it's pretty obvious he meant 1/4 "track".

lol. yeah, if you can't get to 90mph on a 2 mile road/course then your car has other problems :hitler:

[92 mtechnic cabrio]

Not true, you only have a 1/4 mile to run and a lot of cars won't even break 90.
