    Update:

    I had my fabricator create a non-merged system. Sounds so much better and now has instant throttle response.



    Then Valentino Balboni signed my car.



    Then it hit 30k miles



    Then I went to the same dyno inside a wind tunnel where my previous set up put down 611whp



    Then this happened . . .

    Why do we not get a sound clip of this? Also, excellent numbers

    50whp for some ebay headers? not bad at all. How much were they?

    Will get one soon. Thanks!

    Power gains were much better than expected, it also gained 62wtq. Cost . . . about half of the Viper's purchase price.

    Damn, what a gain for a NA engine!

    Need some sound here

    Better than the guy who let Balboni drive his and Balboni proceeded to crash it.

    That's a big gain from one single modification... you sure there's no magic going on to get to that verrrry particular power figure?

    Well, it's not really 'one single modification' and the changes are drastic. Tubular headers with very tight radius bends were replaced with tubular headers with long runners that are .5" larger in diameter; new collectors are designed to not have turbulence; the muffler section has changed from 2.5" to 3" and removed two y-pipe. Also, this is a 6.5 litre V12 that spins to 8000 RPM, allowing the engine to breathe and exhale better makes a big difference.

    Wish there was footage of my response after the 666 pull.

    Duly noted (I know it's a big job, wasn't tryin'a belittle your work - longtime listener, first time caller). I know less about N/A engines than turbos - do you think that the displacement or high redline plays a larger role in the effectiveness of a full exhaust upgrade like this, or do they work in tandem?

    You've got my response after seeing that figure, hahah. If it were mine, I'd have a hard time adding more power

    They work in tandem, so it's a large displacement engine that makes power at high rpm, so moving a lot of air/exhaust and the least restriction to and from the engine makes the most power.

    For comparison, my Viper is 8.0L but only two valves per cylinder, so it isn't efficient at moving the air/exhaust, upping the throttle bodies from 60mm to 70mm has zero gains because the stock heads cannot flow more. Viper's powerband is basically flat from 5200rpm-6000rpm (redline) and Lambo gains about 100whp in that same rpm range.

    It's a pretty good number, no need for more.

    Lambo:
    No updated sound clips, but the 60-130 time, with two shifts, dropped to 7.31 seconds.

    Viper:
    I always ***** the ROE Racing red smooth tube intake tubes in the engine bay and K&N filters were not looking good after their last wash, so I refreshed the intake. Ended up having a collapsed filter.







    Slight 'clunk' putting it into first gear from a dead stop and was a PITA to put the trans in reverse. Prior to a 200+ mile day trip for work I stopped by my buddy's place to change the fluids. With the car up in the air he found the 'clunk', it ended up being a failed u-joint from a loose u-joint strap/bolt. Easy peasy fix right? Nupe, the u-joint took out the differential output stub. While the car was in the air, we kept inspecting it and found that those new motor mounts I put in two years ago had completely failed. After we pulled the rear bumper we found out why the exhaust was always crooked, snapped mount (looks like from when it kissed the ground) and one of the tips melted the bumper cover. So the Viper got some work.

    Long tube headers;
    Modified Mopar/Borla mufflers to 3" inlet;
    Repaired crack in driver's side muffler;
    Repaired snapped exhaust hanger;
    Motor mounts;
    Modified trans cross-member;
    Skip shift eliminator;
    Reverse lock out;
    Spark plugs;
    DEI spark plug wire heat shield boots;
    Battery cut-off switch;
    Raised the car a tick;
    Slightly used rear differential;
    U-Joints, straps and retaining pins; and
    New fluids

    headers vs. factory tubular manifolds


    blown out motor mounts vs. new




    that u-joint damage




    old diff out


    exhaust stuff




    I removed the chromie valve covers from the previous owner, god they were ugly. Magnesium valve covers without paint are much better:

    The answer is always long tube headers

    Changed the beetle's front springs from BC standard 9k to Swift 6k for a bit of a better ride:



    Missing piece of road resulted in three bent HRE's. Sending them back to HRE for a rebuild:




    Oh, and I did a thing. . .

    You did a very good thing
    Excited about seeing what you do to it. I suggest 88 hp per liter?
    Always love to see your updates
