    Having the intake manifold (s?) Machined to say lamborfuckinghini would be next level, just saying lmao. Can't wait to hear it
    Do a ricer full throttle flyby for us please.
    You can daily a monster truck, it's still not practical.

    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?

    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.

    Always room for more power!
