    Hennesey tunes the Mc Laren MP4-12C

    Click here to enlarge

    The first tune for a Mc Laren is here.
    Hennessey makes the MP4-12C HPE800 Twin Turbo
    Besides some extra body panel changes, which should produce more downforce, and a new exhaust there are not many external changes to be seen
    The list of mods:
    HPE800 Twin Turbo Upgrade Includes:
    Upgraded intercooler system
    Upgraded air intake system
    Upgraded ball-bearing turbochargers
    Hennessey titanium exhaust system
    External wastegates
    External blow-off valves
    Upgraded fuel and engine management system
    Upgraded transmission cooler
    Upgraded transmission clutch system
    Custom dyno-tuned engine calibration
    Hennessey Warranty

    Well, I do not to be too critical, but Hennesset warranty ... Dunno if that's an upgrade.

    I think this is just a proposal to tune it. This is nothing more than a daydream and I don't understand why this is getting front page posts on major blogs. It is likely only because of grand claims and Hennessey's name being combined with the McLaren.

    It doesn't actually exist.

    Who in their right mind would give him this car and say let's see if you can make it happen?

    It is ridiculous nothing more than some claims on paper are news as if he really did it.

    Exactly, they might as well claim to be tuning nuclear submarines.

    Bah hah hah hah hah

    I don't think anyone is going to get a "tune" on an MP4-12C without McLaren's permission.

    McLaren makes all of the control electronics in the car, and if they have them locked down, nobody is getting into them. McLaren makes the spec ECU for F1 cars for reference.

    Why would McLaren grant permission to steal their market share in future MP4-12C upgrades / new models?

    It doesn't make any sense to me.


    Edit: I hear McLaren takes security even more seriously than Oakley...and they are known for having bathrooms you need a pass-card to get into! Seriously...I have a family member that has done consulting for Oakley.

    Well, one thing is for sure, that body kit looks WAY better than the original! To me at least. I don't care about Hennesey because they are a JOKE when it comes to pricing. Sometimes even for bolt-on $#@! that they don't even manufacture....

    I give it a 15% chance they will get a tune on it and get it to run right. As PEI said Mclaren doesnt $#@! around, they design their own engine management systems and this is a half million dollar car with a special engine. I know they have tunes for a bugatti, but this is a whole different animal.
    Some people live long, meaningful lives.

    Other people eat shit and die.

    I'm not racist, I hate everybody equally; especially fat people.

    I kinda doubt they spent the effort to make the ecu difficult to get into though. There isn't a high enough likelihood of many people trying. Not like the GT-R where everyone knew people would mod the $#@! out of it. And look what happened there, Nissan says uncrackable, 3 days later, Mine's cracked it.
    Never thought I would see the day...

    Jphn has a very good engineering team...just look at the venom.

    John has really cleaned things up and with Dave on the scene they are putting out quality product.

    Hennessey and his pipe dreams he rarely if ever produces what he says he will or when he says he will. I wouldn't let him tune or touch my cars ever...

    if someone wanted to crack the MP4-12C's ECU it will be done no doubt... i just dont think Hennessey will be the one to do anything to it...

    Ever sat in or driven the Venom? I have and it is unbelievable. John did the headers on my black series and those were some of the cleanest welds you will ever see.

    I have seen it in person but no rides, its a great looking car without question with impressive performance. After he screwed up two Vipers for a friend and a family member I would never rock with him. Hennessey is still bum however!

    Joe - it is truly one of the most beautiful cars you will drive. I would compare it to something but quite honestly I can't. When you step on the go pedal it is the most violent thing you could imagine but is civil otherwise.

    Like most I thought it was simply a rebadged lotus but nothing could be further from the truth.

    What is interesting is the car is now road legal in the states.

    I pretty much considered it a stretched Exige with a ton of power thrown at it. Seems it may deserve far more respect.

    I'll reserve judgement until I hear your impressions from your delivered car.

    I am sorry to hear about your experiences.

    I think in the older days Hennessey no doubt had management issues but with Don on the west coast and David in Texas things have changed. I will have to find the pics of my headers being assembled. They drop the subframe and build the the headers while the engine is still in it. It makes for a very tight fitting and good design.

    All the prototype testing was done by Ben Collins (old Stig) and it is truly a go kart on crack.
