Yesterday I had a new L air intake and 68 mm tb professionally installed and when I tried to run the car past 3500 rpm, the fuel cut out and did not resume until below 3000 rpm. This resulted in a violent rocking of the car during the stationary test. So far the German mechanics are at a loss to explain this. If any of you have had similiar problems and know of a solution, I would really appreciate your imputs.

About the Air Intake/TB Install. I was informed by the mechanics at the local Chrysler dealership that the American cars have a stationary/parked governer on them. When the car is parked, the rpm's will not exceed 3500. I am told that when car is in motion, the rpm's will exceed 6000. I will let you know this weekend.

Thanks

That's exactally what it is, if your in Park it'll cut the fuel at 3500RPM. If you have this problem without the car being in park, you DO have a problem.

I got to drive it home from the shop and it functioned perfectly. I am looking to run it sustained in the 3500-4000 rpm range this weekend on the Autobahn. Thanks for the input, it is good to hear that from more than just the local dealership mechanics.

why is it that they have that cut out? is it to prevent serious damage if you do a nutral drop? (rev in nutral and drop it into drive)

The local mechanics here did not know why, but I would be very interested in knowing that as well.

not usre if this is the same or not, but on my old SHO the ford mechanic explained that the RPM limiter happens due to the fact that the speed sensor sees zero MPH and is trying save the car by limiting it, in other words, if your speed sensor broke you could still drive the car, but only a limited amount.

Not sure how true this is, but bottom line is don't get worried unless you are moving over 5 mph and it happens.

I really haven't had a chance to wring it out yet. I will let you know this weekend. I am thinking of taking it to Oktoberfest.

Hey there Chief Brian - when you finally do decide to get on the go pedal you will indeed hear the TB opening and the sound! ...reminds me of the "old" 4 barrel carbs of years past. You will now hear the change from the low RPM intake runners to the high RPM runners, sounded to me like the K&N filter had folded in half and was being sucked into the intake!!! LOL You'll see, the 1st time you hear it you will think that something ain't quite right and let off of the gas. Good ol' Steve didn't tell ME about it, so when I Emailed him, he musta laughed his @$$ off.

Don:

Is the sound of the intake noticeable while driving at highway speeds?

Thanks

Nooo, it sounds quiet as the stock setup even at 70 something. I'm fairly sure it will always sound like stock even at higher speeds. BUT when you nail it above 3,000-3,500 RPM, that is WOT mind you, then it really screams. I guess I should also tell you that during normal driving, as in away from a light, it is silent as stock.
