Has anyone checked this out yet?
340 to the wheels using only Stilled products and UpRev to tuen it...

Bone Stock: 2010 Nissan 370z Nismo
REAL WORLD this is what a 2010 Nissan 370z Nismo puts down for power..
292 (Wheel HP) x 1.25 = 365 at the flywheel.
230 (Wheel TQ) x 1.25 = 288 at the flywheel.
These numbers were taken from a stock car and may vary.
HP is now at 340 (at the wheels) which equates out to about 425 HP at the flywheel.
TQ is now at 260 (at the wheels) which is approx 325 TQ at the flywheel.
At the end of the day what does all this mean…
+60 HP increase at the flywheel.
+37 TQ increase at the flywheel.

At least they admit the skew

I thought the NISMO was rated at the 350 mark, or am I missing something?

The dyno reads high

cheshirecat · 03-12-2012, 12:24 PM

Very generous dyno. I'd like to see some trap speeds of this 350hp beast.

I have one question.. Why are they multiplying the WHP by 1.25 to estimate the crank HP?

Isn't the drivetrain loss in manual Z's estimated at around 17%-18%..?? I think 25% is a bit high..

This is pretty much my next question. Why 1.25? Where are they getting it from?

Instead of:

Quote:

230 (Wheel TQ) x 1.25 = 288 at the flywheel.

Shouldn't it be:

292whp x 1.20 = ~350hp
230wtq x 1.20 = ~276tq

Then using that 1.20 to finish out, their final numbers would be:

340whp x 1.20 = 408hp
260wtq x 1.20 = 312tq

Is this the wrong approach?

Because nothing is better than a horsepower circle jerk

jezeka777 · 03-12-2012, 12:47 PM

Why is a NISMO with the same mods of a 370z much higher in WHP? Wouldnt they be both around the same power but they are both with the same mods?

ANMVQ · 03-12-2012, 12:48 PM

EH waste of $$$ if you ask me,, I made 298 WHP and 240 WTRQ, Stock headers and stock cats in a 7spd X coupe. For 40 WHP. Stillen's dyno is very generous at best, Their" 515HP SC kit" made 440HP( 365 WHP) before I was tuned. Stillen dyno= INFLATED..

I think they cooked the books on this one.

I wish my bank account could do the same.. lol .... thanks for the reply

BTW: How are you liking the Stillen SC? Ive been wanting to get one but every one has been telling me to go TT.. Do you feel alot of power and can you upgrade to higher boost?

roplusbee · 03-12-2012, 12:54 PM

lol...........that would be nice as well!

I'm loving the kit, The car is a complete animal, Ripped on the HW on Saturday and hit 142 MPH in 5th( With lots of room left).( Yes HW was very clear) Me and one other car..I can up the boost with just a pulley change and return, But for me it us more than enough,, LOL for now, I'm looking into the GTR's pistions and rods

I think that's right and closer to the truth.

350hp (per Nissan)/292whp (dyno)= x(approx. hp @ flywheel)/340whp (dyno)
x=407.53 hp @ the crank.

Still pretty good numbers even if the dyno reads high. You can inflate the numbers, but you should only be looking at the difference from the baseline anyways. My understanding was, that the 48whp increase from baseline is more important than the actual hp reading on the dyno.

This a link on there for determining the numbers they used.

Seems kind of odd. It would mean most stock non-Nismo's should have numbers closer to 345hp at the flywheel.
