Intake Exhaust Moving all that air in and out efficiently

Does the Cosworth plenum give any gains for N/A?

The compatibility of epoxy with a "resin" depends on the type of resin being used. And there are many different kinds of resins. Carbonfiber is typically epoxy or polyester based. Polystyrene resin is almost never used with carbonfiber.

Compatibility is dependant on the chemistry of the resin(s) being used.

But for you to say "Epoxy resin is not epoxy" is entirely incorrect.
To say epoxy won't react or molecularly bond or fuse with epoxy resin would also be incorrect. They will indeed molecularly bond and become one large macro molecule.

Do you have a background in Chemistry, composites or polymers?
blah blah blah the epoxy you were pointing him to was not even close and you can talk in circles all you want but we both know whats up.oh...i have a phd in b.s. and you are a fine study on the subject.

wow-no idea this thread was going to turn into a discussion on epoxies and resins.

Anyways, the install is finished and no expoxy/resin was used. The arc strut bar fits fine and the titan tube and arc airbox fit perfect with the Cosworth plenum. I believe my tech used the hondata manifold gasket, but not sure.

I would have had the car by now, but I'm getting tints done first thing tomorrow and should have installed pics by tomorrow night.

Ok, just picked the car up. The cos plenum gave much better clearance than the mrev2, spacer, and stock manifold for strut bars. Before, the ARC strut cleared the plenum, but was slightly rubbing the underhood cover. Now with the cos installed, the strut can be brought down more and it no longer rubs the underpanel.

Unfortunately, the dyno I use is unavailable until mid next week--so I'll have to see what changes, if any, occured after swapping out the spacer and Mrev2 for the cos.

As far as what I can tell from the seat of my pants, I think I lost some tq/power between 2-3k, but it seems to pull a lil harder from 3.5k-5k, but take that observation with a grain of salt as I have been driving a stock loaner sedan for a couple of days so dunno for sure. I also only drove the car home cuz the weather is still mighty crappy in chicago and I have never seen this many potholes before; also waiting for the tint to fully cure inside where its warmer.

I'll have a few installed shots uploaded soon.

the upper and lower plenum are still attached with the 5/16 spacer in b/w it. I was going to hold on to it until I can a get dyno comparison done and run the car a little more to be sure I'm going to stick w/ the cos, but if I part out the plenum assembly, I'll definetly let you know first.

Well, it definitely looks great. I'll be interested in some numbers.

Guess you like ARC, huh?

I should make it to the dyno next week hopefully.

Just thought I'd share some of the comments my tech shared with me regarding the cos install:

"Just wanted to give you low down on your last visit. Everything went well with your intake install. I managed to retain the thermal barrier for the throttle housing and used the new Hondata gasket. A few things needed relocating but overall it's a great fit. I used my inch pound torque wrench to torque the bolts holding the carbon end caps on as specified which is only about the third time I've used that overpriced tool!! I had a bit of an issue getting the ecu to relearn the idle air volumn value but eventually I got it. It's very specific as to the rpm range and load it will relearn the volumn of air entering the engine at idle. With all the changes to rotating mass and air flow on the intake side it's not surprising.

Your oil separator was full so I removed and emptied it. It seemed to be a mixture of oil vapor and water which is exactly what would be expected. Your oil level was fine, no worries there.

The pulleys all were tight but I did reset the belt tension. I did hear some noise from the belts and I think it's due to the fact that the pulleys are aluminum and the belts will pick up a glaze of alumimum as they wear. Aluminum is soft and will easily transfer a surface glaze. I don't think there is much that can be done. Your front crank seal was totally dry, no leaks. I made a template for your heat shield and will make it over the next week or two."

Side question - does the stock strut brace bar fit over the Cosworth plenum?

Primo8998 said the Cusco fits (any pics of this?) but he didn't think the stock one fit.

What other strut braces have people fit with the Cosworth plenum?

ok, I got the car dynoed and am going to kinkos to have the sheets scanned and put on a flash drive. I will post the results shortly.

Let me just say that the MD setup made more power overall, with a slight twist...

I'm not sure if osiris or another ems would improve the numbers N/A, but I can tell u the MD combo is till the better bang for the buck N/A.

the dynos will be uploaded shortly. Thx for the patience

Can't wait to see the dynos. So will you be keeping the cosworth plenum?
