Refining the performance of the '98-'99 300's - PeachParts Mercedes-Benz Forum

Why is everyone always concerned about the lag when punching the accelerator to the floor? Do you guys really take off like that every time? Mine does the same thing if I punch it to the floor but under most conditions I find the turbo to be quite well behaved. I don't drive like a little old lady mind you, just not WOT except when it's really needed.

And, in the $3 + a gallon time we are in a lighter pedal will result in higher MPGs too, a nice fringe benefit.

PS - I actually drove the speed limit over this past weekend setting the cruise at 65 MPH and drove to NJ and back on a single tank...over 600 miles until the reserve light came on. The car turned in 34+ MPG on 80% highway/20% city, the best I have ever achieved. I might just keep driving it this way as it was very nice not to have to watch for the cops all the time and just let the world pass me by for a change - smiling all the way to the pump.

Only problem with the 606's design is that it's turbo is a tiny KKK K14 so it's already maxed out at stock power levels.

What can we upgrade it to?

Not much without fabrication thanks to it's proprietary exhaust flange. Pretty much anything, even a T3, would be better.

T3 had an upgrade to a T3/T4 hybrid. Can we do that?

With the right T4 wheel and some ECM tuning for more fuel, I'm sure that would be a sweet combo.

I saw a turbo from an '05 CDI on eBay a few months ago that looked like it had the identical exhaust flange - I think it was a VNT Garrett. It looks like it uses an electronically controlled wastegate

Fun factor.

Less fun factor. Gotta pay to play.

In a "theoretical" drive at 85, I got 33 with 99% highway.
