My Ride: E46 330ci Turbo
dyno results

McSpeed finally had a chance to dyno his car with the turbo at one of our dealers (ICS in Stamford, CT). Before we get to the numbers, some background on his car is in order.

McSpeed dyno'd his car right before the turbo installation. His results were:



Notice the power dip above 6000rpm. Obviously something wasn't right, but the problem couldn't really be pinpointed. When McSpeed sent in his DME to us for the turbo software reflash, I read out the diagnostics first. There was a lot of knock adaption stored, especially in the upper RPM range. This explained the stock dyno graph and its top-end power drop. The ECU was detecting knock (real or false, we didn't know yet) and was retarding the ignition timing accordingly. I informed him of the situation and we noted to keep it in mind going forward.

Once he had the kit installed and running (along with the electronic boost controller he chose), he headed over to ICS. They went over the install, and after installing a fresh set of spark plugs, the car pulled about 327rwhp (with 8.5psi and 93 octane). This is the first thumbnail pic below.

Notice the 'squiggly' results around 4000rpm. This is due to his stock clutch slipping. I've also printed the graphs vs. mph to help lessen the visual effect of the slipping clutch. The 2nd thumbnail is the power vs mph.

Now, while these results weren't too shabby, they were about 10-20rwhp lower than I expected. After remembering the knock adaption of his stock engine, I suggested he try some 100 octane fuel to see if the ECU was pulling timing. Thus, he filled up a tankful of 100 octane and drove the car, allowing the ECU to adapt to this fuel. Along with this, he also changed his DISA valve in the event it was the cause of knock. He then redyno'd and pulled ~340rwhp (again at 8.5psi, 3rd thumbnail pic). This was more inline to what we expected.

His final test, if he wishes to do so, is to redyno with 93 octane again. This will determine whether it was the DISA valve causing 'false knock', or whether his engine is truly knocking (higher CR from the factory maybe?) and needs a higher octane fuel to maximize the power.

Definitely. Adaptation-wise I'm thinking it was some combination of dirty plugs, a wily DISA valve and questionable (winter?) gas from a certain station before each of the first two dynos. I could actually feel it pulling timing shortly after I filled up there the second time. Now I'm back to quality 93 and things are feeling allllllll-right.

In other news: I got my grandparents to go for a ride by saying I'd keep it under 70. Nailing it in 3rd gear had my grandpa laughing and grandma grabbing for the roof handle

You can definitely tell it was knocking/pull timing in the upper range bc of the huge abrupt job. There is no doubt that you (nick G.) will set him up with a great tune!
What is the "DISA" valve??
If the motor is truly knocking.... do you think that will cause a problem in longevity?? Or the dme will be able to handle it forever?

The dealership calls it an idle control valve I think. Or idle adjuster valve. Besides whatever it does at idle, its flap also effectively alters manifold runner length at around 4K and 6K in order to generate resonance waves to produce a slight air charging effect for better a torque curve. Right?

Right. The ZHP 4k power dip was caused by the DME thinking the engine was knocking when in reality the DISA valve was making too much noise. It seems like you had a dip at 4k as well but now have solve the problem.

Great numbers! Nick, do you think it would do any well to play with the DISA maps and maybe change where it opens/closes? From the graph it seems like it might be beneficial to open it a little earlier.

Is there a way to lock it either open or closed? Seems like that could also be fairly beneficial for an F/I application.

Can you hear the spooling of the turbo just daily driving? I did not know if it is harder to hear because they are located on the undercarriage.

We had already tried the effect of modifying the DISA's transition point during initial software development. We'd done runs with the DISA on all the time, and off all the time. In our setups, the factory transition point was the best.
