Default Went to the Dyno to get a decent baseline

So I hit up the Dyno yesterday. It was Mustang dyno btw.

Info-

00 RS 5 speed
125k motor
Top end rebuilt 15k ago, Decked heads
Borla header
Custom Cat back 2 1/4 to 3 inch Apexi WS ( big muffler, Not a N1)
93 octane
Brand new knock sensor


135 WHP
145 WT

Not to bad I guess. The car is kinda FS right now, But If I keep it Im gonna do some Deltas and a EL header or test pipe on the Borla.

Well, how decked are your heads? How much of a compression bump did you get?

No need to be a *******. Its not like 135hp is something to brag about anyway and not everyone has access to a scanner.

I am unsure, I am thinking just a standard amount since they were being rebuilt. I used OEM headgaskets for my car, So they should be stock thickness.

watchunglava is right. the #'s by themselves are basically meaningless as far as comparing power/tq between vehicles unless they were dyno'd at the same time on the same dyno with all the same settings. Dyno #'s are more important when used to see changes made on one vehicle... and one should at the least use the same dyno when testing for gains.

I will, If I plan on keeping it EL headers and Delta Cams are going in.

I just love all that trq from 3-4k, Right where I spend most of my time on the highway.

Pretty sure hes not on here bragging about power just posting what he got. And for the arses who keeping giving others crap about there hp readings. Dynos are for seeng your gains. Thought that was fairly comon knowledge amungst tuners that all dynos read differently but will generaly give the same amount of gains. One might read 135 base then after mods and tuning read 150. Same setup on a different dyno may read 145 base then 160. For having to see the plot chart to believe someones putting out 135 is plain retarded.

Common among tuners? Probably! But people have to be reminded or those new to this kind of info that it is more important to look at the difference in mods from a baseline rather than comparing dyno numbers of different people. I used to think that a dyno was a dyno and the numbers were written in stone. No matter what car I read about, they all could be compared to each other, even on different dynos. Kudos to those of you that are trying to educate those on the truth.

In the meantime, the curves look good. No drastic shifts in power and it looks like your hp curve is not falling off too soon. Looking forward to seeing more plots in the future, if you decide to keep the ride.

Oh...is that last graph the air/fuel ratio curve? I can not say that this is normal or not but I have never seen an air/fuel ratio start off rich, go lean, then go back rich again like that. Not saying anything is wrong with that but keeping the air/fuel ratio linear can help with power delivery. I am not a tuner though. Just a street tinkerer who likes to play on dynos. From my own personal experience, I'd shoot for an air/fuel ratio of 13.0:1 throughout the entire RPM band while going WOT. Just a thought!

i dont get it though. our cars are like 105whp stock (well the 2.5i's are), how do you get such a big gain of hp with those mods? is the top end something big?
