Subject: JDM intake spacer causes slower ETs!

Message: I purchased one of JDM's intake spacer kits. I made a lot of
passes testing this at the strip. Initially I ran without the spacer to
get a baseline. I then installed the spacer kit(fighting with the EGR
tube). My truck consistently ran about 5 hundredths slower than without
the spacer. To confirm this, I then removed the spacer, and got my 5
hundredths back. This was all done on the same day. Also, with the spacer
on, my upper intake appeared to be just as hot as it was without it, certainly
too hot to touch without getting burned.

This shows that this product does nothing for performance. It accomplished
nothing but making my wallet lighter. Total waste of money, this thing
cost about an even $100 to my door. That money would have been much better
spent with someone else who isn't making this type of bogus performance claims.

 

If your intake is too hot to touch with the spacer in place you have an EGR problem - You are flowing WAY Too much Exhaust into the intake. Normal operation of the Supercharger wont make the top section of the intake where the throttle body that hot.

Before your condemn the product - Do another test - Get another truck to run you side by side ( neither has intake spacer ) then check BOTH intake temps with IR temp guage... The other one will be hot but if yours is sooo hot you cant touch the instake you have a problem,

There is a thread somewhere about over heated intakes and broke EGR systems.

 

I second what Doug said. Reality1 recently had the same problem with his EGR system, and made his upper intake too hot to touch in a very short time of driving. Maybe he can elaborate if he see's this post.

Is that the cool thing to do? You are nothing but a band wagon tuner bashing groupie! Why don't you start with the route problem of your truck and figure out why your intake is burning? By the way, the "other" "good" tuners also sell spacers, did you know that? It has been proven over decades of racing hundreds of vehicle models that a spacer is a wise buy. I sugest you shut your mouth, sell your Lightning, and buy a Honda....and complain when your 2F2F titanium wing doesn't help you achieve 200 mph like in the movie!!!

 

Austin, call JDM... i spoke with Justin and he has a method to check and see if your EGR valve is not working properly.. I did his test and found out that mine is not working properly.. my plenum gets supper hot... but the spacer does lower ET's when the truck is running properly....it has been proven several times...

 

Not every performance part will perform exactly alike on different trucks. It appears that you have a problem in your EGR system. Just becuase it doesn't work for you, doesn't mean it won't work for somebody else. Adding performance parts is always somewhat of a gamble and some will show immediate improvement while others will show very minor or even worse times. I also find it hard to believe that your runs are that consistent that you can attribute this part to losing exactly 5 hundredths off the quarter mile. That marginal of loss could happen on any run regardless of parts being changed.

 

I called and no answer. Does anyone on the board know how to check this. Mine gets pretty hot as well. No spacer but it seems that it still should not get as hot as it does. How can the EGR be checked?

 

I had Dealer Mechanic Drive my Truck with his Star Tester connected.

This was after installing a new EGR Valve. Found the EGR valve was

not closing when computer was asking it to. I had intake temp at 150 degrees

because of this.

I think Easterisland has these intake air temps figured out. A EGR valve is about 60.00. A Faulty EGR valve can do some damage to Plugs and Valves.

austinLightning, I sugest you check your #5 plug as well

I just post what I see on my own truck. I say get rid of the egr. You don't need the extra heat from the exhaust heating up the water in the heat exchanger while cruising or whenever the valve decides to open. I calculate I have killed 1 child per 5K miles of driving due to the increased emmisions. So yes, it is worth it.

 

Okay, how about some detailed intructions on how to do so?

Thanks,
David

 

Or, a way to check it. I would imagine that places like here in Houston, we cant take it off because of emissions. Anyone know if we can run w/o it or a way to check it?

 

Isn't it a federal law against tampering with the emmision system on a car or truck? I've also heard of repair shops might be found liable also if they work on a vehicle that has had it's emmision system purposely altered and they don't report it. Each state might be different but, it's something to check into before you make the decision to go tearing things out. As I recall, the fine can be pretty hefty.

 

SEC keep trying... I know Justin is there.. I spoke with him this morning... his method will let u know if the EGR is not working properly.. or take it to a dealership and let them test it

 

Just remove it......

Cap the header/manifold where the tube connected to, also cap the plenum.

Can the EGR opening immediately before the upper plenum just be blocked off with a plate? ...meaning, I wedge a piece of metal between the EGR and plenum, and bolt it back up to keep the exhaust gases from entering...

Would that be an option? Then it still looks stock
