RJC Power Plate Hot or Not?

[turbo nasty]

Is it still effective if you use a spacer plate? And do you place it above or below the spacer?

Just went through this with a friend. It goes above. Called RJC and thats what they told me

It's below the spacer plate. Though, if your spacer does the trick, would you need the plate too?

If you use a spacer, I think you change the dynamic. Meaning the RJC plate for the stock plenum/TB is designed for just that. The spacer itself increases volume a tad but not intake air distribution.

Pretty sure Jason markets this as an air distribution plate.

If you use a different plenum/TB combo, you would then need to get the corresponding distribution plate.

I have had one for years and could easily get 1.5-2 psi more before I started to tickle the knock sensor.

Well researched and designed precautionary device. For the price, you simply can not go wrong.....unless you gorilla the nuts/bolts.

that would suck since i put mines like this
1-Dog house
2-Spacer plate
3-RJC PP
4-Intake manifold

I hope Grumpy is sleeping,because I am sure he will have an opinion on this.I think Razor has one on his car also(not sure though)I called Jason when I bought mine and was very well informed.Some combos are different.

Can this be ran with the plate? Intake Plenum Spacer, Heads & Intake, HE-IPS | Cotton's Performance Buick Grand National Parts & Service
Will it be a waste? If so what thickness for street driving?

 

[turbo nasty]

Yes plate on the bottom/lower intake side of the spacer

i second the stud use. 8mx1.25. You loose 1/4" of thread contact However, If you use the bolt, hold the ratchet wrench close to the ratchet part and use one hand. It makes it harder to over-tighten. I had done this for years without issues but i eventually blew out a thread not paying attention. I use studs now.

What is the point of the spacer?

What is the point of the spacer?

To increase open plenum volume and slow the air down between the cylinders and the throttle body. There is an ideal size plenum volume for every size engine and the max operating rpm it will have. More is better than not enough suprisingly.

 

[usetaboost]

so is this one of those "if you're running 10s you might need this" items?

How about street driving? Plenum spacer and plate? Plate is on it's way as I type. What thickness plenum since a few are offered?

We run plenum spacers in our setups and have no correction to keep things in order. For the most part the PP is a pretty good part, but the end user should take steps to see it is working properly for his combination.
