What do you guys think? I might even coat the bottom of the collector with swain tech to keep the heat from the engine away.

 

ooooooh so shiny... mine's supposta get in today.. we'll see.. it's been 2 weeks since i ordered it!!!

 

wow nice and shiny. how much hp/tq would it give.

 

I dunno, Tony from Motordyne said it cant hurt,that it would do nothing but good, so i figured what the hell, why not..

 

Looks good. Now someone just needs to try this on the same car with the original MREV2 and then the polished version. Did you get the inside of your upper plenum polished as well?

 

How much does it cost to polish it?

I'm still waiting on mine.

 

Holy Krapola!

Now thats a polished plenum!

 

HOT HOT HOT!

was that a DIY project? Or did you send it out to get polished?

 

+1 but it's supposed to come in today so we'll see.. btw you missed a good meet.. you should check the TX forums once in a while.. we have meets lined up.. from now on, we'll be having a meet every 2 weeks. PM me if you want more info on it

 

Sent it out to get polished. It was like $150.

 

Tony. I had the whole length of the runners polished too, but now im reading this:

From The Science of Horsepower: Porting & Matching Heads & Manifolds, Larry Carley, Underhood Service, November 2001

"As for polishing, Mondello said a smooth finish is great for exhaust ports, but a rougher finish flows better on the intake side. He recommends using 300- or 400-grit paper followed by a Cross Buff for polishing exhaust ports, and 50- or 60-grit paper for the intake ports. A slightly rough surface texture in the intake ports and intake manifold runners creates a boundary layer of air that keeps the rest of the air column flowing smoothly and quickly through the port."

Does that mean i should not have polished the whole length of the runners? Maybe i should have just left the inside of the runners how they were?? Is what Mondello is talking about "boundry layer turbulance" talked about underneath??

The inside of the runners in an intake manifold can also be coated. A single layer of a dry film lubricating coating (DFLC-402, DFLC-404 or DFLC-401), also known as ?fluid retaining coatings? treates the fuel/air mix as it passes through an intake manifold on a carbureted engine as a "fluid in motion" and can reduce fuel drop-out by creating boundry layer turbulence. For maximum gain, first apply a thermal barrier (TCD-201) to the inside of a runner, then a dry film (DFLC-404) over it to not only create the boundary layer turbulence, but further reduce the amount of heat that does enter the fuel/air mix.

So would a layer of Dry Film coated inside the runners be beneficial? Help Help Help lol.

 

I don't know about the coatings or what they will do. But, I do feel a little skeptical of coating claims in general though.

But like I said previously, Rickdogg and I pre/post dyno installed a polish of the runners and it had little effect. It only produced a 4 HP blip about 500 PRM wide, convieniently at the HP peak.

You can search for his post for more information.

 

I cant find it! He has over 4000 posts and has started 215 threads...Did he start the thread? Do you remember who did? Do you remember any words that were used in the title of the thread?

 

If you can imagine a water flowing through a tube, the friction on the surface of the inside of the tube cause the water to be very turbulant on the surface, and the center obey's the rules of laminar flow while being constricted by a layer of turbulent water. Thats what a "boundry level of air" is.
I'm pretty sceptikal (spelling...lol) of that claim. I'm also skeptical that polishing would make a huge difference, unless you're nitrous.
