I know with all you guys out there that have the Euro-R manifold someone can help me out. I'm looking for the plenum diameter and length and the runner length from the plenum to the flange. Thanks.

 

???

 

i have one sitting at a friends house, when i pick it up im get you those specs, if you don't hear from me just PM to remind me

 

What I need is for you to measure one of the runners from the flange to top of the runner in the plenum, the inside diameter of the plenum, and the length of the inside of the plenum from the far right to the throttle body flange.

 

I should have this for you later today. sorry for the delay.

 

Thats great. Thanks guys. No one around here has one or I'd try to get them.

 

I've got one at home. I'll take the mesurements tonight for you. Question; do you think your all motor header would fit in a 97 CL coupe with a Euro-R motor? I have alot more room up front than Accords or Preludes.

 

Damn, I say your instant message but I cant reply to it because I'm new to this site. I forgot the manifold is at my friends house. We wre going to modify it to work on his H22. I'll go to his house later and get them for you. In you rinstant message you mentioned that the header came out 10.5 inches. Is that at where it comes out of the block at the top or at the bottom where the crossmember is?

 

Basically the header looks like this __] It comes off the head about 10.5" and then goes straight down and turns under. Just measure 10.5" off the head and go straight down. If there isn't anything in the way, you won't have any problems.

 

Ranta18...when you sell ur crower stage 2's let me know

 

I traded them for the Stage 3's. Great deal. He got the 3's and they were way to big, so we did an even trade.

Any updates on those numbers guys?

 

damn

 

Ok Mike, I got this Euro-R manifold right in front of me. The length of the runner is 9 1/2 inches. The length of the plenum is 11 1/4. The diameter of the runner changes from top to bottom. On the bottom it is oval shaped at 2 inches side to side and just under 1 1/2 inches high. At the top where it goes into the plenum, it's about 2 inches around. Let me know if you need more info.

 

Inside plenum diameter? Thats great. Thanks a lot. Those numbers are close to what I was figuring for a custom NA manifold, but my runners are a little shorter for higher rpm.

 

Give or take a few mm the inside dia. of the plenum is 2 3/4 inches.

 

Good stuff, I was curious about this as well.

 

Cool. Plans are a 3.5"-4.0" Dia. plenum, 8"-9" Lg. runners, same runner diameter and shape but with a "velocity stack" on the end of each runner where its in the manifold. Thanks for the email with the pics too.
