      The purple car never had a sri. Had a real abv when Billy had it and stock or the gutted vgi when I ran it.

      I shifted 6500-6700 with the 262s and 268s for the other gears from what I remember.

      As Paul mentioned, I never used anything other than the Euro manifold and any track gains from that alone were highly suspect and questionable. My exhaust manifolds and downpipe were kept totally stock and untouched as well. My set up was a simple one, people often confuse what I was doing with other people's efforts; that's not directed right at you, just in general... the forum hearsay, etc., etc.

      I'm looking at it as, even with the current 7200rpm limiter, their should be HUGE gains everywhere in the band I am currently using so there is no downside. Then when I break down and get real management, it will just be the icing on the cake. I did up a head to support them, and already clayed, dry fit, and cut pistons for them, so no turning back now. Just need to get to buying another set since I lent mine out, which turned into selling them.

      I still need to make a manifold, but its going to be nothing exciting compared to alot of others setups. No protruding bellmouthes or anything fancy.

      I was shifting just before 6800 with those cams; the few times I did take it higher had me on the limiter too quick which was counter productive and inconsistent (for me). As far as management, it was already mentioned, and I agree, that just running a chip with a raised limiter is going to work well. Techtonics should have an adjusted file for these cams somewhere if you’re looking to get the most out of a chipped ECU, that being said the regular GIAC cam file I used did the job, never acted up, never ran bad, once the off throttle idle was sorted out (ISV, throttle stop, etc.).

      I just re-read this; I think I should add powerband details at some point...

      This discussion makes me wish I had the 288s in a motor with good compression. Would have broken the 12.83/198whp curse.

      Precisely why I'm going bigger pistons in my rebuild and keeping it n/a doing some headwork and throwing in DRC 268's and calling it a day. Fully blueprinting the engine though, The micrometer and bore gauge have been going non stop to measure and double check measurements a few times over before the block and head makes it over to the machine shop.

      Again, awesome Thread for everyday life

      Got question and need your kind suggestion from those who run CAI that is bent down like mine is:

      I have noticed that my MPG increased dramatically after 2-3 months after CAI Install, at first it was all fine but it seems that this K&N Filter sucks and holds too much dirt from the ground, and sometimes in the rainy day even gets wet. I don't even cry about huge puddles which may kill engine

      How do you solve those problems? and how often do you clean your filters? Maybe put it back where it should be, but with hot air ?


      This is my CAI Setup:




      You can see here a plastic screen in front, which prevents dirt from the front bumper to stick to the filter via air, and its also covered from bottom, from behind there is a plastic Wheel Shield, and still it gets dirt and wet :



      This is CAI From the top (Notice that cheap solution of the tube, im still not sure about Turbulence and stuff, pl make suggestion if u can):



      Larger View:



      P.S Sorry if the PICS are too large, I don't know how to make them smaller

      I clean my filter once a year. My vr6 isn't my daily. It gets driven to the track and on nice days in the spring, summer and fall so I don't really worry about rain or puddles all that much.

      Mine is in a mk2 but I have custom ducting feeding air from the fog lamp opening to the filter. The rest of the filter is protected by the fender, wheel liner and lower air guide attached to the bumper. Even being 3/4 covered by metal and plastic shields, it gets dirty pretty fast.

      You could always try one of those prefilter wraps that go over the filter. Jeep guys run them over their cone filters to cut back on dirt and dust from the trails clogging up the filter.

      I have an idea floating around in my head and would like some feedback from the resident VR gurus. I've been looking at Water/Meth kits (yes, I'm N/A) and thinking that running one would allow me to run the 100 octane GIAC race tune on 93 pump gas at all times.
      I realize the gains would be minimal and there are many other things to spend that amount of money on, I'm just throwing an idea out there. As an added benefit, I believe the W/M setup could really help in high summer heat. I know the VR runs hot and can take it, just call me paranoid when I look at summer water/oil temps, lol.

      Thanks in advance guys.

      Use a prefilter on the CAI. I got mine from outerwearsracing.com was about $20. Call them, tell them which filter you have and they will get you the right pre-flter. Also helps repel water. Also if you want a one piece pipe on top google 3" aluminum pipe with a 70 or 75 degree bend, 24", a bunch of turbo piping will come up, I got mine for like $30. Pic does not have prefilter on it.

      or go on ebay and search "vr6 cold air intake" they are about $30 and just change out the filter for a k&n or aem and works perfect. I have one and very happy with it

      go to www.verociousmotorsports.com
      get yourself the following:
      1x 120* 3" pipe with smaller radius
      1x 90* elbow
      3x 4 ply couplers

      you can route the 120* bend to use your maf in stock location, eliminating the stock elbow.
      then route the 90* with the piece cut from 120* and run that in the fender.

      you can always run the filter in the bay on days that it is raining to prevent from soaking the filter.

      K&N also sells a bag type deal to put over filters

      I just want to take 5 sec to thank "root beer" for one of the most thorough and useful posts I've ever seen on ANYTHING. It took a lot of time and patience to put this whole thing together, but I've found myself referring back to it again and again.

      Does the MK4 Head gasket fit 'straight on' onto a MK3 12V euro-head?

      I've got told there needs to be modifications and all, TS tells there should be no mods at all in order to fit. Free extra compesssion is always welcome

      Nothing special about "euro" heads. Drop in as long as the cams arent huge or running aftermarket forged pistons. If you have either of those, check clearances.

      I have a Neuspeed CAI and instead of using the supplied air filter, I used a smaller filter that I found on the K&N site. I also cut the intake after the air meter and installed a AEM bypass valve. Just in case. I have a euro lip with the euro lower splash shields as well to keep water from splashing on the filter. Its covered pretty well and still gets lots of "cool" air. I'll try to snap a pic and post it.

      I don't think that would be a terrible idea.....I'd dyno both setups on the same day for a solid comparison though. Also, you make it sound like water/meth is expensive.....An n/a setup only needs a single nozzle setup, and everything can be had new for $260 (see link below). Because VRs run so hot, water/meth is a great idea for preventing heat soak and generally keeping intake temps lower all the time so you get the most timing advance possible. Use this method in conjunction with the mk4 IAT sensor for the best results.

      If it would have been strictly a temps thing, external oil cooler and low temp t-stat would have gotten the job done without the hassle of having to fill your reservoir up.

      Are there significant gains to running the race gas tune? Even with an mk4 HG, I don't see how anything over 93 would be need to pull top timing.

      Wrap your exaust for lower 'hood' temps. Saves alot of heat soak also.

      Well I finally got around to reading all of this, excellent everybody

      The only thing I could think to add, someone told me fuel volume was the difference of the square root of pressure change and the square root of 5 is about 30% more than the square root of 3, not as simple as I thought. (which I've posted wrong somewhere and been off the grid for a couple..) When e85 is stochiometric it is faster and the vrs still seem to pull timing at operating temp so the gas tunes should benefit I would think.. I think it would be worth a try if even just blended with an AFPR and a wideband. I can't remember if the stock stuff holds 75psi to redline wot..
