How to add top end power and prepare for a turbo all at once

Step 1: Save some money.
Step 2: Have expensive taste.
Step 3: Save some more money.
Step 4: Buy expensive toys.
Step 5: Have way to much free time the day your expensive toy arrives.

The result? Check it out.
16 hours, 3 friends(Mostly for company other than my buddy Alan :P), 4 different auto parts stores, many spliced wires and tube extensions, some taco bell, and a starbucks frappucino later:

Please ignore my incredibly dirty engine bay, ghetto rigged intake, and incredibly long hosing which I need to shorten...

Anyhow, finally got it all in, and it's running, it's just very quirky...

a) I can only seem to rev to 5200 rpms, won't go past that.
b) If I hit the gas hard suddenly, it makes this odd popping sound.. kinda scary
c) It surges on occasion..

So yea.. not done yet, but I thought I'd share...

You may want to angle the intake ontop of the tranny. Where it is it will be taking in alot more hot air then cool air.
When you say it won't rev past 5200, thats in gear right? If not you'll damage your engine and the engine may actually have a auto shut off at 5200 so you don't do sever damage, it could also be the ECU rev limiter.
Is the popping like backfiring?

x2.

otherwise, its hawt

are you still running stock ECU???

if so does it matter how the MAF is angled???

nevermind, i answered my own question, well at least the first part.

im still wondering about the MAF though.

[jettadude]

angle shouldn't matter. it only measures how much air by how much it cools the heated platnum wire and some stuff. its not like the A2 ones where the air moved that little door and stuff.

I fixed taht problem long ago :lol:



Anyhow, I've been talking with USRT, and they think the main reason it's running oddly is because everything else on my engine is stock. It's not surging anymore, but the rev limit is still there. I'm going to see if it's there in different gears though, cause I think it might only be in first. Either way, the guy at USRT put it like this: "what you've got there is like a genius student twiddling his thumbs in a special ed class and getting frustrated at the rest of the kids."

So I'm looking into getting a new cam right now, and maybe a temporary chip until I save up so I can turbo. Oh, about the intake, that's still temporary, I'm going to run it up behind the headlight next to the battery, I just have to get the right tubing to do that.

oh, forgot to address the popping issue. I don't really know what it is yet, but I have a feeling it might just be hitting something when the engine torques.. Definitely not loud enough to be backfiring.

with those manifolds doesn't one cylinder get more air. what makes it even. it looks like the one closest to the TB would get the most and the rest would run rich.

Don't know, ask USRT :lol:

At the moment, I'm probably running lean though, since I don't think the stock chip handles this manifold so well :lol:

So I installed a 260 cam the other day, to see if that helps. Definitely smoothed out the powerband, but I accidentally advanced the timing 6 degrees when I did the cam, so I should probably fix that. Also have a GIAC chip waiting to be installed when I get the chance. I think the chip ought to bring it all together so I'll feel the mods more, but it's sort of hard to compare my current setup to what I had since it's been running like crap for a while. There's definitely more power than before, but I haven't quite figured out where that powerband is yet.

[jettadude]

could it be the TB, its mounted on its side and its electronic controlled so maybe thats messing with it.

I just reread my post and realized I made it sound like it's still running badly.l After installing the cam, it runs great, the reason why it was running so badly before was that apparently I didn't connect the throttle body plug all the way. Stupid mistake that I found once I VAG-COM'd it. Can't wait to install the chip, but I should probably fix the timing first.
