    Dinan testing their race prepped S62 for the Rolex 24 Hours in Daytona January 26-27

    Think they can win it? I love that they are racing the S62. I wish Dinan took this same approach to some of their street stuff, as in, building it to the highest level:

    Any guesses on output?

    SWEET!!! As my research goes I have found my new love
    I think they will see over 700 hp but will use maybe only 550 or so.

    700hp n/a is impossible...

    550-580hp it will have in reality.

    Why is 700 impossible?

    Already did in 2011.

    They have the best shot every year, since Ganassi runs their engines.

    I already posted my estimate.

    I know one S62 that has more than 600hp,and that has a custom made block and new cast heads as well as custom crank,so not really a S62 anymore.

    Why do you think 700 BHP is not possible remember the motor is not atached to a drive train, so they can scope just what power they are dealing with..

    I think you are confusing this with wheel HP somehow.

    This is not a 700rwhp suggestion by Dinan, it's crank HP. It's on an engine dyno which is measuring crank HP as it's attached to the crank.

    A stock S62 is 394 crank HP.

    over 300 crank HP on top is simply a bit .... OTT. Unless of course as S62SR says, it's basically no longer really an S62 anymore especially with regards to the combustion chamber and crank etc.

    Now you know what a graph looks like where the engine is really making an extra 80hp over a stock motor and it's flywheel calculated.

    Now, someone care to draw a graph to show what the graph of a 700hp motor would be expected to look like?

    Then, when you convert that majic number and put it into graphical format suddenly you see what is and is not possible.

    The Dinan Stroker S85's are claimed to make around 620hp. However, when put on an independent dyno where also many other M5's go, they make ..... wait for it.... 500rwhp
    BUT, our cars with just headers, tune and a pair of air filters....make 500rwhp on the same brand dyno's

    So... are we making +120 hp from our upgrades? No... on our dyno we gain on average 50-60 and our dyno calculates flywheel figures very close to what it should be based on the fact that stock cars read about stock flywheel calculated.

    So, you get where I am going with this...

    and just to add to that,

    We all know what stock cars do on a dynojet on average. 430-440 approx. Talking about S85 here just to make clear.

    Dinan engine comes along quoted at 611 HP according to their website which is relevant to the stages which have been independantly dyno tested and they barely hit 500rwhp

    So the rwhp gain is on average at best 60rwhp. Convert that to a flywheel gain.... that's around 70 flywheel.

    Now 507 + 70 = 577. Not 611. A massive 34hp short.

    Take also the Dinan E39 S2's. They made around 370 rwhp. Stock car makes about 320-330 on the low side even.
    Our cars with stage 3 make anywhere from 375-390rwhp.

    We make more power yet quote much less final HP.....

    I actually like Dinan so don't think I am hating or anything. Just I get a little curious at the real world vs quoted HP comes out of some companies around the world and because I do not like HP to be devalued I choose to point out just the facts and therefore patterns.

    Dinan just does super conservative tunes and they don't even address the cams.

    So how the S62 in the Ascari A10 makes 600hp? Is it a completely new engine?

    I always wondered how...

    Here is one of our VAC M6X series engines, pre-shipment, equipped with several of our custom parts, and our M6X ITBs. In this state of race tune it generates "well over 600 HP" N/A in reliable and competitive form.

    http://store.vacmotorsports.com/vac-...nes-p1448.aspx

    You would think the S62 can make more.
    Honda CBR 1000RR, Superbike Supply, Arrow, HRC, BMC, Lee's Cycle, Galfer, EBC, Revzilla, AXO, Dainese, Scorpion Helmets

    Honda Grom, most fun you'll ever have on 2 wheels.

    It likely doesn't make what they claim but the S62 can be heavily modified to get close or meet that number.

    Mountune Racing who used to build the S62s for Ascari is apparently a big name in UK and has done some nice works. I don't think they are making up numbers, that would hurt their image.

    The big Euro names seldom back up their numbers. I really don't know. They need some dynojets in Europe.
