umm im sorry to say this but that dyno is off by A LOT

your car is completely stock and your pulling harder than a lot of people with a lot of bolt on's and tune

generally 6mt should read about 235, GENERALLY, and 5at about 225, but dyno's are really used for tuning purposes, and its the gains off the baseline that really counts, none-the-less, thats one healthy g35! great job!

edit: just saw your other thread, is this with your non revup upper and lower plenum and 5/16 spacer?

 

Yea my other post is with an entire non rev up assy. I snagged a non rev up upper, lower and intake manifold had them port matched to each other and cleaned up the casting marks a bit.

The dyno runs in this particular thread are bone stock, revup upper (no diff in the revup vs. non-revup) and revup lower.

The first run is because the car probably wasn't fully conditioned for WOT use like all the tips on dynoing recommend. (Make sure you do a few full WOT runs to tell the ECU its time to focus on max performance before you start your runs). The 2nd run is pretty monster, but to be more conservative, runs 3 and 4 would be decent runs to look at on the safe side and it shows a pretty awesome engine nonetheless.

at 297 rated hp, the car would have to suffer 21% drivetrain loss to hit 235 whp... and at 15% (what I am just assuming is possible, chime in if someone knows for sure), it is 252.45 whp. Either way that engine is strong, simply because it is doing what its rated at!

 

Thanks for stepping in white. I can understand the skepticism, my car did read freakishly high which everyone can see, but what I am most interested in and wanted to share was the delta gains from adding a non revup lower and a spacer on a completely stock setup since most of the dynos I've seen always include some sort of additional modification (exhaust, test pipes, intakes, etc). Take the baseline at what it is, it's just a baseline. It's the delta we should all be interested in!

Now if more people would ring in on the other thread...

don't get me wrong, i love my coupe to death. but whats the deal with the VQ? i know it won like motor of the year a bunch of times but how? with all the oil consumption issues and then looking through some of these stock dyno runs 230-250whp when the motor is rated at like 298hp. that sounds like some killer drivetrain loss. did nissan overrate the motor? or is all the VQ glory and praise based on the non-revup motors?

 

Drivetrain loss has to be fairly static, so really its just the motor. The problem with these machine built motors is there is a wide range that peoples motors can fall in. I think what happens is they rate motors that are just "ringers" and then post those numbers similar to what is speculated about the GT-R motor specs. So if 298 is what a machine is capable of but only happens a small small percentage of the time, then who knows how low the average is. The only thing you can count on are gains from mods rated on the same dyno and 1/4 mi/0-60 "real world" times.
