Hey everyeone,

I love this site to get help.
So I installed K&N 69-1211TTK Typhoon in 2009 Accord 2.4L last weekend.

Everything was installed properly and securely. After the installation, I started the car and accelerated to check the RPM. I found out the RPM cuts off between 5000 and 6000....or I couldn't accelerate above this on the parked car. Is this normal.? Is this how it suppose to be.?

The other thing I found out that the provided coolant bypass hose b/w
the throttle body and thermostat housing gets really HOT. Is this normal?

I have checked all the connections, No leaks and did a road test. Everything looks perfectly fine. Runs great, gained some horses .

Can someone please explain.?

Thank you

 

I moved your thread to the general tech help section. Please read the forum rules and do not post help questions in the DIY section.

 

Sorry about that.

I have occasionally heard stories about a lower rev-limiter when the VSS isn't measuring any actual road speed. It's not real good to run up to redline without any load.

In other words, try again in 1st or 2nd gear actually driving down the road.

 

It isn't just Honda engines; most modern OBD-II engines won't allow "revving" beyond a certain pre-programmed point when there isn't a load on the engine. I'm actually surprised shan5 got it above 5,000 rpms; 3,000 is far more typical.

 

I talked to one of the K&N Engineer. He said the car can only take so much. Temperature hose does get hot.
On the freeway, it was going above 5000rpm <6000rpm when accelerated. For normal smooth driving, gears were changing <=3000rmp. I'll really accelerate soon on the freeway to see how it reacts.

When these two things happened, I thought I did something wrong. I checked the steps again but looks like everything was normal.

Thanks guys

 

Jim and Shipo have it.

The '07 Pilot (bone stock, you know me ) is the exact same way. I forget the exact point but in park it will only go to ~4k, then the limit kicks in.
