Not too bad with an air filter that has 40k and a stock exhaust with a couple of holes.

you are at just under 150Hp with a turbo? was the turbo worth it?

That's like 190ish at the crank or so?

Do you have a chart of your AFR as well Serge?

The A/F mixture is pretty crappy. AFPR is a piece of crap, half of the RPM band it's too rich, and the other half is too lean.

A couple of points:

This was a 'base' run to see how my A/F mixture is doing.

The turbo is barely making 5PSI, it will eventually be bumped up to 7-8.

The airfilter/exhaust are taking away the top end. It can be seen clearly after 5.5k. There is still MANY more horses lurking around. :)

Do I feel a difference? Hell yeah. I have almost 180ft/lb of torque at 3.0k RPM with the peak at around 3.7k.

Holly crap, your AFR's are crazy! It's like dropping a bouncy ball to the ground, LOL. Do you think it's a software issue?

Any ideas what your stock figures were like before FI'ing it?

This is the only dyno of a stock 318 that I have. As you can see, stock A/F isn't the greatest as well.

50% more torque at 5PSI is not bad at all.

I did a dyno on my previous '92 M42 years ago and the power curve was quite smooth. And from that dyno plot you posted there are so many dips in the powercurve for the stock 318. Was this dyno from an M42 or M44?

Thanks,

Didn't know stock 318's are so slow, my eta can burn that, and it sucks.

wow i always knew the stock fuel map had a big hole in it in the middle rpm range. thats running crazy rich at 4500rpm. once i put my JC chip in i noticed how bad it was and how much more accurate the JC chip was.

Umm, I think most of the people here are fogetting these dyno's are all done at the wheels (chassis dyno). It's almost impossible to get engine dyno figures without physically taking the engine out of the car.

The 150HP that Serge's untuned turbocharged 318 is producing, is more than a stock 325, so how can you call that slow? That's almost 200HP at the crank. And that 120RWHP of the stock 318 is actually 140HP at the crank. Just wanted to clear that up. I think some of you were getting the impression that Serge only gained 10HP because he was comparing stock 140crank HP with his 150RWHP, it's actually really good that he gained 20-30RWHP, that's a lot!

those are good numbers, remember too, not only do you have 150whp but your lighter then an inline 6, weight to power.

Crank that turbo up a bit get 8psi, and get that computer remapped, and 100% you can get 175whp. That would be about 210crank.

but anyway 150 is good, and tq numbers are really great pushing 180 in a lighter car is great for that feeling of power.
