261 whp on a 287 hp motor thats nuts!

 

Just keep dynoing it and soon you'll be over 1000whp.

 

 

Something is just to fishy here, i have popcharger,5/16 plenum,utec,clutch,flywheel,test pipes,single exhaust,headers, and im making 266whp and 243tq. Your numbers just dont add up!!!

 

how are you making 266 with ALL that stuff? I couldnt see those numbers with stock ECU or a reflash but with UTEC? who tuned it?

 

nice lol. what ya optin for? SC, TT, or ST? surprisingly few guys that run cams with F/I setup that I've seen...be interesting to see your numbers. any other headwork? P&P?

 

No headwork I feel it wont need it to make around 600-700hp just same cams and cam tuning. I have the money to turbo it now but I decided to move. lol.

Able 2 fly, Dyonjet dynos generally post higher that actual numbers because there not a electrically loaded dyno. generally to you multiply 1.17 to Dyno Dynamics numbers to get a dynojet numbers. How else could Stillen state that Their stage 4 superchargers added 100hp to the VQ engine. PS stillen uses Dyonjet dyno in their horsepower exaggerations.

 

what about Dynapack? Z Mania above you apparently made way more power on a Dynapack than on a Dynojet.

 

Here's my stock 05' ( just a K&N drop-in)

 

your power CROAKS at high RPM....wowser.

 

Looks like they just let off the gas too soon.

 

Yea, apparently, the math involved in accomplishing such a feat escape the OP. I think the post by BrazenZ could explain what's happening here.

240whp probably,

250whp unlikely,

261whp

 

Pop charger FTMFW

 

Peak HP comes at 6200RPM. (it's not the rev up motor) But 251 to the pavement? I'll take it.

 

The Z that did a dyno pull just before me, (03 performance, also stock, with a drop in filter.) pulled a 234.7. -Just minutes before I pulled 251. ( I don't think it was a "happy" dyno.) I think there's just more than 287 at the crank. (It's not a math trick)

 

So you believe Nissan's engine tolerances are so outta whack then? Most companies have a set tolerance range, appears that is not the case.

This would also mean there is probably some sap of a 350Z owner with a stock car putting only 190 or so whp...

Personally, I don't believe the dyno the OP posted. It's either that or his vehicle isn't stock.

 

this is why i hate this forum.
out of all members here only one other guy believes him
only a bunch of haters. lol yah i said it. hate on that too.

however, it is factual to say the more you keep flooring it.
the better the computer learns it.
i find this true because a buddy of mine whom has a non-rev-up
got it tuned with orisis and saw almost 5whp out of his tune.
why? only 5 when there was shown 15 plus dyno pulls of change.

i believe it is because of the computer that is in our cars
it does alota learning in the NA bolt-on phase.

so stop saying its imposible and go out and drive the hell out of your car more.. but do it safely please.

show of hands how many people on this thread floor there car everytime they get in it. or most of the time anyway?

 

Another reason for the higher than normal HP numbers is air temp, humidity, and altitude, the 05 base Z is supposed to be 287 @ 70F, 30% humidity at sea level, If your close to the coast and temp are 50 degrees and humidity in the 20%, I suppose that 20hp or more is possible. With all that said, Don't take these numbers too seriously. Dyno numbers are like a bathroom scales they make not be 100% accurate, but they can tell you if you losing on gaining weight. Do a baseline run, add you modification(s), then test again on a day with close to same temperature as your base run on the same dyno.
