egr block off

[Boost_Lee]

yea at WOT, doesnt the egr system disable?

OK! but I'm not arguing the fact of the basic functions of the EGR. I'm saying temp and other factors has too be better, there for it was almost better for HONDA to maybe figure out something better than a EGR since they didn't use it on all there engines, Whats the factor with those.

[Shadow1]

right now im just trying to figure out if it would be better to just take off the EGR since its not really needed and put on the block off plate.

You take it off if you have emissions be prepared for your car NOT to pass. Your NoX readings will be higher than normal. They have other options for cooling a phenolic gasket in between would be one. Another thing Honda EGR systems are not really efficient. Main cylinders that get the exhaust gas is 3/4. 1/2 get some but its not an equal amount. If you clean out the IM and such then yea. And EGR does close at WOT.

What if you bypass it and then have ur car tuned, wouldn't that be the best way?

[NAiL05]

Most likely.

The egr is there to help recirculate exhaust gases, and the main benefit from it is to improve emissions and fuel milelage, I know that an EGR also lowers the combustion chamber temperatures as well. But i dont know how early the EGR was introduced, and really how efficient it really is with our CB7's. I am pretty sure if i had a EGR on a new car i wouldnt take it off, cus it seems like that would be bad, and i am sure they are way more efficient and important everyday driving, and engine life expectancy

It doesn't do it at idle though, that would stall the car. It has to be a high enough engine speed so it won't kill the engine. And I believe it does disable at WOT, the car goes into its "balls out" mode if you're WOT, ignoring its fuel efficiency measures.

in my opinion i would take it off. Especially since i am going to go with a chipped p28 anyways so its going wether i want it to or not.

I'm not going to be polite so sorry.

The egr does NOT increase combustions chamber temps...it does the EXACT opposite!

The egr REDUCES the combustion chamber temps guys...you should really learn about what your cars parts do before you start messing with them.

Taking it off will increase your risk of NOx and knocking.

It will not increase horsepower by any percent AT ALL.

The egr does not operate at WOT.

The egr does not operate at idle.

The egr ONLY operates when you are cruising at higher speeds.

It puts a minor amount of exhaust gas into the cylinder which reduces the combustible amount of gas...giving you a lessened bang...thus decreasing the temp.

This increases fuel economy.

But it only does this at idle...the INSTANT you raise your rpms...it stops doing this.

This is a pointless mod and not worth being done...so undo it...quit wasting your time with it.

Another pointless mod that I put in the same category as this is taking the vacuum line off the fuel pressure regulator. Make you dump excess fuel even at idle.

Please learn what you are doing before you do it...you are wasting your time and reducing your fuel economy.

The best advice for you on this...is undo it...and put it back the way it was. Even if your egr was clogged...get one off a junk yard and replace it...knocking is not cool.

very true. but if that is the case why is it not on b series???

[accordaffair]

They didn't put it on sportier engines as far as I can tell, just on more economy-minded engines.

[bcjammerx]

I'm no engineer...but this engine was designed with it in mind BUT...I guess it is possible it won't do any harm...but there is no hp gain since it doesn't operate at wot...imo it's not worth all this trouble
