Re: beaterX project thread

Instead of powder coat you can just spray paint it with that rubbery spray I sprayed my piping with (forgot the name already, same stuff TKR was using on his engine bay). Then when it gets a little scrape or something, just spray a little more on and it blends in fairly well

Re: beaterX project thread

Does your upper pipe not have a flex section on the pipe for the engine rocking back and forth ? If not that could cause that pipe to crack from flexing on accel and decel. A suggestion would be to add a flex section for the engine "rock" right where it cracked and have the tube flanged on both ends. That way you don't need to re-powder coat.

Re: beaterX project thread

Hump couplers work quite well on single piece UICP's allowing for enough movement. That's how my Nisei and the Cobb piping kits are setup.

Are the Cobb and nisei setups one piece construction or welded together aluminum pieces to form a single piece?

One solid piece, no welds.

Re: beaterX project thread

Quite the fun last few weeks with this thing.

Before the cruise, I did a boost leak test and found a few cracks in my POS UICP. It came on the car, I'm surprised it lasted as long as it did...I patched it up with some coupler material and clamps and frankly I'm surprised it didn't break in half on the cruise.

Instead, the car ran 110% perfect for the first 175 miles or so and while passing a car from a stop sign (legally!) I grabbed second gear and thought I hit a bunch of gravel....turns out it was my accessory belt eating itself!



I shoved my wife into another car and then buckled down and with the help of my friends put that shredded belt back on! Limped the car 30 miles to Ashland and found a belt that was 103 5/8" (stock is 103 7/8"...that's like 8.5 feet, 1/4" should be fine eh?) and put it on in the hotel parking lot. Note to self emergency kit in my trunk does not have a 16mm wrench needed for actuating the tensioner. I did a few rips after and the car ran great!

Next morning the new belt ate itself after 40 miles but in a delightfully awesome way...one of the six ribs shredded off, leaving 5 full ribs. I actually drove the car for about 450 miles like this:


When I got back, I ordered up the Hyundai 4b11 pulleys that apparently fit....and are METAL NOT PLASTIC! Effing plastic pulleys, seriously mitsubishi? Reading online, it seems everyone commenting on these things failing is right around 40k miles, just like me. Effing silly.



Look how freaking worn those pulleys are! The one actually had a goddamn groove in it. No wonder the belt was walking off! So I put these on with some spacer washers as Shawn (simulatedwoodgrain) suggested per Murlo's car, but the belt was hanging off the inside edge...so I removed the spacers and left them as they came out of the box (but with the mitsu bolts) and swapped pulleys around to put the best plastic one on the tensioner. I'd love to put a metal one there, but I don't think it'll fit...will order up a new plastic one sometime here and have it handy.


Work has been extra-insane the last week but I managed to stumble across this deal on evoM:
http://forums.evolutionm.net/evox-sa...5-shipped.html

I LOL'd and brushed it off, but then thought to myself, fuk it! Easy fix for my UICP...instead of just welding mine and getting it re-powdercoated, I'd get a new one! So a few bucks later this is at my door:


Came with t-bolt clamps and nice couplers, even a nice long reducer for the turbo outlet:



Dyno day saturday so no time to get this thing powdercoated...slapped it in tonight:

(note, after taking this pic I got the pipe to sit lower and closer to the radiator support by pushing it down into the hump coupler more, fits perfect!)

I must say, the old pipe must have been leaking a LOT because the car feels freaking awesome! I'm excited to see what she puts down on Saturday!

Re: beaterX project thread

I ran my car with an entire rib missing for like 500 miles as well. I didn't even notice for like 250 miles. Silly system.

Glad to see you have gotten your shit straight! Can't wait to see it on the dyno. I'll let you max the EF4, I am going to play it safe

Nice, that reducer coupler has a nice transition who made it?

EDIT* I checked your other thread, nice price compared to the other guys!

That transition coupler is really nice, I like it! No mounting brackets on the UICP though?

Hah don't expect anything crazy, I don't plan on pushing it...I'll be running my usual 30psi as my fuel system is at its limit anyways.

Dunno, it was just in the box.

Yup it's a nice piece! I'm actually not even using it on my car yet b/c my car came with a modified turbo outlet pipe that transitions to 2.5" on its own. It's not very smooth but it doesn't appear to be holding me back yet I'll probably sell it with my (soon to be) fixed old UICP.

No brackets, that would just add cost I guess and I don't really think they are necessary. I kinda like not having them actually, lets the pipe move more when the engine rocks. It would definitely 100% eliminate blown I/C pipes but other than last night (forgot to fully tighten t-bolt on intercooler) it has never ever been a problem for me on this car.

That being said, this car drives *amazingly well* with a blown I/C pipe. On a DSM/CT9A maf-based evo you would be hard pressed to make it anywhere...I actually drove several miles back to my house and just fixed the car in the garage, no issue...just light throttle.



Oh, and in other news, my LTFT's decided to start working again! Checked this morning, right at 1.5%

Re: beaterX project thread

New pipe looks nice. I always use hump couplers at the very ends now a days as well to allow for some flex.

Re: beaterX project thread

Well, the car is missing about 25-30whp IMHO but that's how my luck rolls with cars I'm fairly certain I have gunk on my intake valves again, need to run some pump gas/injector cleaner through this thing and see if it improves...should have done it before yesterday but meh, life's busy.

MitsuStyle.com spring dyno day yesterday! We were a little down on car count so we put my car on last and Shane @ DB Performance tweaked it a bit since it's been a year since it's been really dyno tuned. First pull was 467whp, final pull was 499.7:

This is a 1.0CF Dyno Dynamics dyno.



Walbro 400 + BAP + boomba rail + FIC 1680's are doing their job pretty well!


Still some taper, but we had some odd fueling issues so just left boost like so:


and dynojet/shootout numbers:



Got it on the road and afrs went a little leaner....so I realized last night that I need to really finish/re-engineer my air filter heat shield situation. I have a small shield that I made temporarily out of my stock exhaust manifold shield but the stock snorkel bypasses this and blows right on the filter....I have the primo intake and the maf sensor is placed right by the air filter, at the end of the pipe...I haven't looked at other manufacturers, but IMHO they should be moving the sensor back a good 6-10" from the filter inlet to avoid what I'm seeing.

I love having fresh air blow right to the intake but I guess it's causing problems. On the dyno afrs are rock-steady in the 11's, but I hit 13's on the street. Last night I had a eureka moment with all of this and I temporarily blocked the snorkel with my temporary shield and AFRs instantly dropped to where they were on the dyno.

So I ordered one of these:
http://www.ebay.com/itm/370609679924

We'll see how well it fits and how functional it is...if it's all good then I will get it and my new UICP powdercoated wrinkle black.
