Whp vs. Engine hp?

Pelican170

Lol well when i find the thread about it, ill post back...

Dizon248

You don't even need to find the thread, how the hell can 5whp give you 19bhp? that's nearly 400% increase. Like someone mentioned earlier, if i had a 300whp car, and do 400%, i have a f'ing 1200bhp monster. Yeah that sound right to you? NO!

AGAIN listen, that 5whp is probably just exhaust, there are other things that probably give the NISMO an edge ok? Engine tune would probably be one, I'm not sure of the differences between NISMO and non NISMO, it's obviously more than a damn exhaust.

You obviously have horrible reading comprehension, so let me break it down for you.

19bhp or 15.77whp difference from NISMO vs non NISMO probably includes:
(again, I'm not sure of the differences between the NISMO vs non NISMO in terms of what gives it that extra 19bhp, if someone can chime in on that, it would solve a lot of problems)

engine tune
exhaust
other crap

the 5whp YOU got is just from non NISMO + exhaust, you're missing 10 whp, and that is probably from the other crap + engine tune. GET IT?

Does this work?

Assuming 332hp @the crank & 275hp baseline @the wheels.

332 bhp x Y (whp gain)/275 whp= X (bhp gain)

Example 1:
20 whp gain

332 bhp x 20whp/275 whp= 24.15 bhp gain
Total bhp @ crank: 356.15 bhp

Example 2:
5 whp gain

332 bhp x 5whp/275 whp= 6.04 bhp gain
Total bhp @crank: 338.04 bhp

Unless you find an example of a NISMO and a Sport run back to back on a given dyno, your numbers will mean nothing. From what I've been able to read, I've seen a larger difference in HP. The only post of a 5 hp spread I've seen back to back was between the standard and the automatic. Generally (since every dyno gives differnt numbers) I've seen non-nismos usually hit in the 275 range and nismo usually hit around the 290 range just going from memory. That would yield a 15 hp diff at the wheels and about an 18 hp diff at the crank assuming an 15% drivetrain loss.

Well, thanks for the a**hole remark up above lol. Other crap on the nismo?? False. You obviously are the wrong person to be chiming in lol. Its just a discussion, settle down there chief lol

You are looking at it wrong......even though he is wrong too. Your view is correct, a 400% increase, but when looking at percentages, a 400% increase is not reversed as a 400% loss, it is on roughly an 80% loss. Big difference in numbers. But still, his math does not add up.

THANK YOU!!!!!!! You got it!

Dizon248

I wasn't looking at 400% loss, I'm looking at it at 400% increase, going from 5whp to 19bhp is about 400%, 380 to be exact, and yes I know 400% increase =/= 400% loss. That's why I corrected the other person's equations in page 1.

Cooo!! I didn't see the post above by the guy that did the proper math. He is spot on.

This is a good point....

Pelican170

Yes this makes sense. Obviously what i read about the 5whp diffence from 19 bhp was incorrect, which is why i was curious in the first place...

Geez.

NISMO 370Z (2009– )


2010 Nissan 370Z NISMO
The NISMO version was introduced for the 2009 year model. The engine produces 350 bhp (260 kW) at 7,400 RPM and 276 lb·ft (374 N·m) at 5,200 RPM with revised ECU settings and exhaust setup. Transmission choice is limited to a 6-speed manual with Nissan's new "SynchroRev Match" function. Handling is improved via stiffened springs and stabilizer bars compared to the 370Z Coupe. Other equipment includes 19-inch RAYS forged aluminum-alloy wheels with Yokohama ADVAN Sport Y-rated tires (P245/40ZR19 front, P285/35ZR19 rear), 14.0-inch front and 13.8-inch rear vented rotors, NISMO Sport Brakes with 4-piston front and 2-piston rear aluminum calipers, and a fully integrated chin spoiler.

Taken from Nissan 370Z - Wikipedia, the free encyclopedia

So the thing that is causing the differences between a NISMO and a non NISMO + exhaust is the ECU tune, which was what I said earlier. That is why the guy with a non NISMO + exhaust was only getting 5whp, he is missing the ECU tune that the NISMO has.

And Pelican, sorry about earlier, I just got a little heated.
