Just don't get it on anything else! Hahah

I will try this when I clean up my plenum pre-installation

never said it was a big deal. maybe took 4 hours total. better than paying a bs shop 200+$$ hard earned money. oh having a 20 gal compressor doesnt help, try 80gallons.

Alright guys! Finished my lower runners tonight! Took some pictures with my cell phone; First pic is of the heads' side, second pic is of the lower plenum side; third pic is a close-up of one of the runners to the head; and fourth pic is a close-up of one of the runners from the lower plenum.

Very shiny! But trust me, it's not super smooth. I didn't smooth it out too much, just polished with some aluminum polish and I will clean the whole thing off with some of that airplane paint stripper before I paint it!

Some pictures to keep folks entertained:
























I'm about to tape off the lower plenum right now to prepare for wrinkle coat on the exterior of that as well. I will post more pics when I get it painted, and when it's installed / comparison to the old one that's on the car now.

looks good, very smooth... I dunno if it makes a difference but I left mine slightly rough because I heard if its too smooth it actually does worse since there isn't enough turbulence to mix the air and fuel before it gets into the cylinder.

Theres 2 sides that will argue for days on that.

I heard the same as well Rob. But I've also read that it really only applies to carbureted engines, and only in parts of the engine where the fuel mixes with incoming air. So I'm really hoping that it being too smooth doesn't affect it in a bad way. I just sprayed the lower plenum exterior last night, so that's drying all day today and I will be installing everything tomorrow. I also just installed my single exit exhaust Wednesday, so I hope that combined with the exhaust, I really feel some improvements tomorrow.

If it at least sounds better, post up a vid.

Hahaha yeah exactly, that's why I figured I'd just go for it and smooth it out. I only went up to 220 grit.

Either way, it should sound freaking sick, especially because I'm doing the upper plenum (which is also cast flashed and polished) and the 3/8" spacer. I'm really excited to get it all on.

^- your work looks very, very good... I did the same thing to the lower plenum minus the runners below... didn't have the necessary tools to get in those tight spaces :/ I did however smoothen it out as much as I could by hand sanding but not extensively... oh well maybe every little bit can help

any thoughts on dynoing?

Looks awesome.
what tools and accesories did u use?
and roughly how much time put in?
Pix of items would be appreciated

Pfregeolle would have to do a before any after dyno one after the other within a relatively short period of time so that all parameters are roughly the same.

Pfregeolle would more than likely have to pay for 2 sets of dynos as well

Im sure all of us would be interested in those numbers though

I got a lot of interest and people asking for me to dyno before and after, but I just didn't feel like taking the time to go up to a shop, have it dyno'ed. Then sit there in the parking lot and install everything then re-dyno it hahaha But I'd love to know how much it makes now. It's been kind of raining lately in my area so it's hard to really get on it. But it does feel like it's pulling harder, especially in 3rd. I think I might disconnect the negative terminal and reset the ECU just so it can re-learn itself with the whole new setup.


Tools I used included a sander and some REALLY low grit paper to take the front two runners down about 6mm. A dremel tool with some 80 and 120 grit flap sander bits for getting into the runners. And some aluminum oxide sandpaper from 60 grit up to 220 grit, and a little of 1000 grit in a few spots to really smooth it out. Honestly a majority of it was done by hand, which REALLY SUCKS! I probably would never do this again. If I did, I might do the Intake Manifold (lower runners) again because that was the easiest part of the whole process. And maybe try and sell them or something. I put way too much time into all this hahaha But I guess it's worth it. Overall this has been a year-long project. But you have to remember I flashed and polished both the upper and lower plenums and the intake manifold. So probably a good 60 hours or something retarded like that. I just installed everything yesterday, I have a few shotty cell phone pix from my Facebook, but I also took photos during the install and I will post up the good ones tonight. In the meantime here are the cell phone photos:

Looks sweet.

When u say FLASH AND POLISH, what is flash?

I was just about to post a link for you haha But did you find out what the casting flash was?? If not, refer here:

http://www.aircooledtech.com/casting_flash/


Basically just getting rid of all the excess aluminum inside the runners from when the plenums and manifolds are produced. Less air flow restriction.

ahhhhh gotcha.

I know what you are talking about now. Just wasnt familiar with the term FLASH

where is this number coming from? I've heard differently.

I measured the difference between the MREV2 and a non revup lower plenum.
I measured with a measuring caliper.

LoSt

I picked up a non revup lower plenum to port out a bit. How much should I take down the front runner? Two posts up says the mrev is shaved down 5mm, is that the 'best' or optimum amount?

Work from pfregeolle above looks awesome. Might have to buy a dremel now, was gonna tackle this with a grinder, files, and sandpaper.
