AMUSE 370z puts down 403 hp 342tq
 

Saw this on the amuse FB page don't know what exact mods they have on the car or Dyno settings but numbers seem extremely impressive for NA is the 370 finally able to crack almost 400hp NA, things are looking up.

It's on a Dynapack which read high, and without a list of mods, hard to believe an NA setup that made 400 when not even the highest NA setup thats been published hasn't even cracked 350. :ugh2:

I'll just leave this here...

That explains it looool sorry didn't notice that thanx for pointing it out

Yeah that definitely explains it. That's basically gaining 60whp, which many heavily modded 370z's do achieve.

I got excited then saw it was a dynapack.... :-(

haha what a epic fail. i knew there was a smell of BS when i read the thread title. nothing against OP more just about the claim they made of 400WHP

That's a lot of torque for N/A

There is nothing BS about the gains. 70 hp and 45 lbs seem pretty good to me.

Yea maybe bhp. No way they are at 403whp. If like to see a list of mods and some proof.

I bet if it did produce 403whp only being NA a lot of ppl will go and buy the same parts that Z has lol :bowrofl:

That dyno claims a baseline of 338 ps and winds up at 408 ps... a gain of about 21%.

Most stock Z's dyno around 275-285 on a dynojet... a gain of 21% on that would put it in the 332-342 range. High, but a few have hit that with full bolt ons, tune, generous correction etc.

So... the reported values are considerably inflated (relative to dynojet numbers) and the proportionate gain, while on the high side, is not unheard of.

I'm glad you made sense of it. :icon14:

Dynapack are the most acurate of dynos compared to mustang dynos that aren't relatively accurate. since dynapacks are connected to the wheel hubs and not rollling on a roller.

If it made 403 WHp they have corrected it because the last time i checked Whp was at 389-390.

has anyone actually seen or posted a mod list for this supposed 403WHP car? maybe a video too? i mean i'm sure you can throw any car on the dyno and put the name in as a 370z then post it to a forum claiming 403whp.....just saying

...................yeah, they added another sticker on the car..............:icon14:

The photo says 'Flywheel Horsepower' so they're either running the engine on an engine dyno (unlikely) which makes the number irrelevant anyway, or they've just put a guestimate multiplier on the thing to make the numbers big.

:werd:
it's "estimated" bhp

Looks about right if they threw on, say, a 20% correction factor.

if i estimated mine i'd be at 405-418 depending on what % i used.

Has anybody found out the real whp of the amuse car??

That's not WHP it's crank horse power. If I had to guess mod list, amuse header, HFC, y-pipe and exhaust.

My car is at 318...you loose 20%+~- through trans and diff. So that puts me at about. 380off the flywheel. Use has 403 which is about 320. Interesting...

also if you have a 7AT you lose even more vs a 6MT from what i understand.

That is correct because of tq converter.

so it's like 25-35% then for a auto

makes my car seem like a monster then lol :stirthepot:

Lmao yeah thats why I will always drive a mt no matter what. Not sure of the difference but it is noticeable.

well 324 at wheels x whatever percent you want to use for 7AT+RWD = a lot more than this lol i'll take it :tiphat:

:bowrofl::bowrofl:

I think the 6spd is 15÷ and the auto is 18% loss through the drivetrain.

Nope...I read it in car and driver...its a fact.

Accuracy in terms of repeatability can be gotten on any dyno -- HOWEVER, there tends to be greater variability from shop to shop (i.e., dynamometer unit to unit of same brand) in dynapacks, mustangs, and other load holding dynos, which tend to have a great deal of variation in calibration parameters.

I personally prefer dynojets simply because the degree of variance from unit to unit is negligible. It just calculates speed of rotations of the known and constant weight of the drum (roller) and then interpolates torque.

That means (transient factors, such as ambient heat and humidity not well accounted for by correction factors, notwithstanding) a dynojet reading from one part of the world is much more comparable to findings from any other dynojet anywhere in the world, whereas the same is not found to be true for most other dynos, all of which may be calibrated a bit differently.

I'd be pretty happy with 400 crank hp on a NA bolt on Z. These things react to mods equivalent to a V8. Exhaust, intake, and tune... boom. That will hold me over until the decision to go FI.

I know this is an old thread but I saw this video on their Facebook page:https://m.facebook.com/powerhouseamuse
It says it puts down 400ps with just an exhaust and their hi-tech ROM

How legit u think this is?

Not at all.....

Seems legit.....:ughdance:

Its probably power at the crank, not the wheels. Makes more sense that way. Plus its Dynapack

BTW I think my headphones are broken from listening to that video...

Not even crank HP with exhaust and tune only. Total bullshmidt.

400 crank hp = 352whp with 12% drivetrain loss. no way is that car making 352 with just exhaust and tune. i think the highest NA on this forum was 342 and that was with a lot more than that

where are you getting only a 12% drivetrain loss? That seems awfully generous. Looking at stock dynos drivetrain loss seems more like ~18%

Wouldn't the loss be more like 18%? 332 chp stock but we normally put down low 270's. So 400chp would be 328whp. 328 is more likely.

A lot more parts but also incorrect correction factor. That 342 is more like 328 if you want to get technical.

Lol beat me to it.
