simple - take out engine, strap to dyno, fire the bastard up.

then see who's telling porkies.

And you think people get up to some fiddling with chasis dynos, what makes you think engine dynos are any better?

All the same tricks still work on an an engine dyno, plus you have a climate controlled room that you can play with. How much more horsepower does it make if we lower the room temperature to say 5 degrees compared to a 30 degree day outside?

We are talking especially temperature sensitive turbo cars here, with intercoolers, oil coolers and large radiators. How much horsepower does it make if we lower the intercooler temperature to say -5 degrees, mix in enough cold water to lower the water temp in the heads to say 75 degrees and keep the oil at a nice 100 degrees?

Plenty of fun for everyone

Cheers

isn't that the whole point of DIN ratings for power outputs?

conditions are standardized for all engines??

why on earth is power at the engine relevent (esp when comparing it to another car)

the only thing that matters is how mcuh power ends up at the wheels

unless they have found some way for the engine to push it along the road directly.

maybe they have those guys are pretty smart

+ 1000000000

BUT

then what number would holden put on the back of their cars... 307 sounds a LOT better than the more realistic 230 or so............ i'm just surprised they dont use hp... (411 @ fw)

    • @GTSBoy This method was able to get readings of -10 to -2, so it looks like its monitoring.  Now I need to figure out why the vacuum on the line provided isn't alternating with manifold pressure.  I went with 2 lines that an RB25 tuner recommended but I'll get a longer hose and try directly off the back of the manifold.  He may have been used to OEM intake setups while I have a DBW setup that removed the MAF and IACV.  
    • I work at a car detailing and tinting shop called Quark which gets all manner of German cars in usually (mainly due to a contract with Mercedes Benz Kita Osaka, BMW Nishinomiya and others) but every once in a while something special comes in, like a fully restored 1972 HS30 Nissan Fairlady 240ZG... The shop owner had immediately started applying film to the windows as soon as it was in the shop so the interior was completely covered in towels and plastic sheets. But I could get a few photos of the engine bay which was restored like new. Such an amazing car to see in pristine condition in Japan these days.  
    • Was going to say the car pulls up nicely everywhere, especially going into that last long right hander before the main straight. Looks like a lot of fun.
    • Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?
