I agree with Sinan, I was very disappointed with the day and somewhat embarrassed till he went. I thought I had a bum motor or something. Either other people have been setting their dynos to read high or something else is up. I know the shop owner of extreme and he's a stand up guy, can't see him trying to setup anyone for failure. all I know is what people have been posting for stock results and both of us hit well below that..... I dunno

all I know is I want answers. I was expecting to hit in the 280's and got 255.

 

Any graphs we can see?

Dyno's cannot be arbitrarily set to read high. The factors that need to be taken into account are the "correction" (done by the tuner) and atmospheric changes/variable (temp,altitude, air density, etc).

I've only seen numbers vary that greatly on 1) FI cars and 2) when corrections are made.

 

Your higher numbers are uncorrected and the lower numbers are SAE. Now normally uncorrected vs SAE wont vary that much on the same dyno but given the different dynos and different CF explains the difference primarily. I had like 292 uncorrected and got all happy till they corrected the numbers, lol.

 

thestereogod was suppose to get my graph. he can post it up.

 

your sig is saying 283 whp. i have test pipes and an exhaust. doesnt my 258 seem too low then? could i really lose that much power?

 

here is my earlier one from altered:


And here is the one from extreme (smoothing = 3)

 

least you didn't get a 160whp pull in 3rd gear. I did 4 pulls in total, two in 4th, one in 3rd, and one in 5th. the 5th gear was the pull was the highest and the 3rd gear was the lowest.

 

the one thing I can say is atleast we have steady straight graphes. goofball, what'd you make?

ps. I'll send you some pics that my parents took of you dancing in a few days.

 

not necessarily. conditions, the difference in our exhausts and the dyno's themselves could account for the 25hp difference. and from the 07 dyno's I have seen so far, 283 has just been on the upper end of the spectrum so I dont think yours is that low. My thoughts are that trap speeds and 1/4 mile times are much better indicators than a dyno. If you can consistently trap 105 or higher I would say your right there with most of the other HRs.

 

where did you dyno at rkemp1?

 

hey bros, i made 253 whp...did 3rd and 4th gear pulls..both read exactly the same...253whp...216 torque

one point i did 21 whp! it was awesome! my car sounded soo sexy on the dyno

 

does that sound about right for you?
and yes it did. really sexy

 

well with the cams and full bolt ons (minus plenum spacer), i was hoping to get 280...around there

 

so... you are missing just about the same amount of hp i am too haha. i was hoping to break 280 as well...

 

my car sounded the best, but you slackers weren't there yet. :nod:

I dunno, we'll figure something out soon. what'd the other z that dynoed make?

 

lol it took me like 10 minutes to explain to him that the 07 had a NEW motor. he keps saying... YEAh.... the rev up.. and i was like nooo the HR. over and over again.

i dont remember his numbers though. i think he was around 250

 

gator? the silver Z with carbon fiber body kit etc? he made 239 whp


we should all get our cars tuned and dyno'd again! let me know if u guys wanna meet up and dyno...we need to get that 280, 290whp locked down

 

yeah that one. his car looks really good. im not a fan of the back up camera but yeah.
He was with me when we were trying to hook up my car without much success..


im down to do that. im not happy till i see that number haha. i actually pmed dave at function tuned about dynoing there. when he replies, ill ask about a group dyno. i want to do it there because i want to get a third shops number.
if there is any other shop that you would like to dyno at, let me know (preferably closer than F:T lol) . i dont know of any other dynos around here.

 

i just found out theres a performance shop in columbia..dobbin center called BRZ performance, they said they have a dyno there

 

cool. well any day is fine with me as long as its after 6 weekdays. i get off work at 6 all week days.
did they mention pricing?
