Hey all,
First off, let me just say how thrilled I am at the job Prime Motoring did. It looks clean and like “factory”.Im very happy.
Secondly, I didn’t get too much driving in today, but first impression is WoW. It’s a completely different car. The clutch is definitely firmer but it’s still comfortable to drive. I got used to the grip after only a few blocks. The throttle on the other hand, is taking a little more to get used to. The car just wants to go go go!
Hopefully I can more “break in” tomorow.
Hey guys… I’ve been having trouble bring my car over 4600 rpm. At first as soon as it hit 4600 it felt like the throttle just closes. We opened up the intake hose to check the reenforcement, it was there but it spun out of position. It was reinstalled properly.
It’s still dying out up top but not as violently. Could it be a defective hose? Anyone have this problem?
How do you know it’s pinching shut? or that is what your guessing becuase it isn’t coming off?
The throttle body does close at higher RPMs to limit your power, but if you truly think there is an issue I’d contact Jake@JHM, Prime, and go out and get some good logs for them to take a look at.
Euros is correct, we start closing the throttle body in the upper RPM range to protect the engine. If you feel something is still off kilter, take it back to prime. They are a great bunch of guys and they can figure it our or get us the correct information we would need to solve this issue.
if the metal brace is there, and installed correctly you should not be getting any collapsing .

You also need to understand that JHM protects the customer from themselves. Whenever the motor gets too heat soaked the ECU will protect the engine by cutting power big time. Like Saki said, if it is hot and humid and your tearing around with back to back pulls…guess what, your going to feel down on power. It won’t feel like it somtimes does when the car is nice and cool or has optimum air temp/density.
The other guys said it as well the hot humid days eat top end power. Go look at some of the recent data from the NA RS4 guys posted here. Even the na RS4 starts to struggle in hotter weather vs the colder morning weather.
Can you take a picture of your engine bay. Make sure you have your cold air intake from the front of the car over the air filter. That Maes a big difference. Between that and the fact that JHM needs to limit the power of the motor to keep it alive (as our motors are very weak) your going to be experiencing the throttle shutting in the upper rpm. Last if prime reset the ecu it will take a few days before the ecu adapts.
