I fabricated a plate to bypass the egr valve. Hopefully this configuration will not cuase the computer to throw a cel. I have reset the codes and will test it out tommorrow.

 

What is the purpose of this?

 

another mod thats just as good as rocket boosters?

 

granted EGR spits out lots of junk... but wouldnt it have been simpler to tap in a filter or catch can?

 

a catch can would connect to the PCV valve which i think everyone highly modded should do... the EGR exhaust gas return enters else where and this too could be good to look into...

 

I did on my better performace but light on drou me crazy only using at the track

 

you drunk? LOL

 

Most people that remove the egr report less mpg and the computer can do some funky things, but it will keep the crabon out of your intake.

 

Actually I do have a filter on my pcv line. Anyway, the codes came back. I have one more idea to try and fool the egr valve.

I'm doing this becausen it icreases my boost response Greatly, sincen I'm superchargen.

 

OK, I just finished fabricating a manifold plate for the egr valve. I have the pcv valve line now flowing through the egr valve to ported, not manifold vacuum. Hopefully the computer will see enough flow and won't throw a code again.

 

Finally success! I ended up having to make two plates, a block off plate on the mount for the egr, also a plate to direct flow from the pcv valve thru the egr, to a vacuum source directly behind the throttle plate.

This is a nice mod for the s/c'er .

 

Can we see pics of this? Nice idea there Chemmech.

 

I can get pics, but don't know how to post them .

 

email them to me, I'll host them. rtatsutani@cades.com

 

Expect multiple e-mails. I have juno and they suck . The plates are just raw stock cut to fit, in a rudimentary way.

 

 

seen any increase in boost?

 

time for a dyno. there is a pre-plate dyno, right?

 

seconded ^^^

 

The egr valve is open slightly at idle and fully open at cruise speed. What has improved with this mod is my boost response. The power delivery is more cosistant and comes on immediatly as the throttle is opened . The lull in power is gone.

A few weeks ago I fixed something that did increase my boost. I re-routed my pcv valve to mount into the fitting directly behind the throttle plate, instead of onto the Intercooler. This way I no longer lose boost thru the pcv valve. This made a big jump in power all the way to red line.

Basically, I'm trying to improve what I already have, without spending money.

 

After my last dyno (low #'s), I knew there was more power to be had from the engine .

I was seeing 250 whp, which the power dropped off, like falling off a cliff, at around vtec 4800 rpm.

 

I'm seeing 6.5 psi at around 4500 rpm when the rev limiter kicks in, since I can only check it in park (I don't have pillar gauges, just a mechanics compound gauge).

 

I thought the PCV valve is a one way valve? If your is flowing both way, you need a new pcv.
