MOTORDYNE ART pipe NISMO--DYNO RESULTS!!

sixpax · 01-11-2012, 05:11 PM

I am just trying to learn here, so put the flamethrowers aside for a moment.

I have been confused about how come stock and on the sticker when I bought the car it says 332 HP ... and then convos like these where a Z breaks the 300 mark with aftermarket bolt ons. I don't get it.

332 is at the crank. Dyno numbers are at the wheels. I dunno what the drivetrain loss numbers are on the manual & slushbox, but they're usually 15%-18% on most cars. You can always get crank numbers by pulling the engine and putting it on an engine dyno vs. a chassis dyno.

Cool thanks ... +1 for explaining and not burning.

Cars lose power thru the drivetrain. All wheel drive cars lose even more. Our cars dyno like 250-260whp on a mustang dyno and 270-280 on a dynojet. The Nismo dynos 15-20whp more usually.

I was also at this dyno day, my car put down 287hp with ARK cbe and K&N typoon, no tune. This was with the 7at in 4th gear, tried 5th on the 3rd pull but hit the speed limiter at 6800rpm. Made more torque in 5th so it probably would have made a little more power if I could have gotten that extra 700 rpms.

Those numbers sound great and legit. I dynoed 310hp/256tq with berks hfc's, k&n typhoon and nst pulleys (Nismo model). So with the test pipes I can dig it. Great job op!

As far as I know, dynojets don't have calibrations. They are set the way they are from the day they are new. The only thing that comes to mind are the rollers might be a little worn. Outside of that, you have a few options: SAE correction, STD correction, and weather correction. There are no other modes or correction factors like on mustang and dyno dynamic dyno's.
