Sorry I couldn't post the graph it wouldn't let me.

[ARCANGL]

what kinda compression... because no offense i thought it would make alot more than that.
My car made those numbers with more tq with just bolt-ons. Although STD

[JoeKelly]

10.75 or just a little over. To be honest I thought it would make more then that also.

[BULLITT1992]

Id like to see the graph if you can figure out how to post it. Do you have the file or can you scan it in?

[ARCANGL]

wtf.. 10.75:1 compression.
damn... im in the middle of going to those heads/cams. Id be a little upset if i lost 15 hp and 2 ftlbs to my VT2 only car!!

it should be finished before school starts again in Jan... we are def gonna have to compare numbers/setup

[BULLITT1992]

Wonder how much of that is the tune or if there is some restriction. I dynoed -18 hp and -2 tq short of that with only a canned tune and o/r h-pipe. Like ARCANGL, mine are STD not SAE

[JoeKelly]

I have the dyno sheet saved on my computer but its in a PDF file and it wont let me post it.

[modularmustang]

what kind of dyno? mustang dyno reads a little lower then a dynojet dyno. Something to keep in mind.

[win98nogood]

heres my numbers on my 02 GT
2002 GT, Motor has manley forged pistons .30 over, manley rings, Scat H-beam forged rods, Stage II ported PI Heads with oversized Ferrera valves, manley nex tec springs, bronze guides, Custom grind Comp cams installed, Built & Dynoed (have sheets), ED Clark custom tune for NOS, 70mm throttle body, Ford Focus Fuel pump installed for the NOS, UPR Cold air intake, CompuCar Adjustable NOS installed with a 90 shot (have jets up too 175) Kooks long tube headers w/ BBK X-Pipe & flowmaster mufflers, plus more!
The numbers are all motor- 284.98 rwh with 294.54 tq this is with the rev limiter set at 6k, stock injectors, stock mass air meter, Now on a 90 shot we all were pretty impressed with 399.21 rwh with 433.76 tq on 93 octane

[JoeKelly]

they use dynojet dyno's. I figured it would be around 280-290 hp on the motor myself

You can send it to me if you want and I will take a screen capture of it and send it back to you. That should do the trick. If you want to do that my email is MississippiBullitt@gmail.com

[JoeKelly]

sent to you

[ARCANGL]

hope that works... id really like to see the graph.

How do those cams sound BTW?? Im hoping not to lose much chop over my VT2's but these have a lot less exhaust.
And how did it rev? Where did the power start to fall??

I'll post it up for him

[ARCANGL]

well power is def fallin off faster than my VT2's did... nice plateau of tq though

[BULLITT1992]

Over 250 lb/ft from 3000-5750 probably feels pretty good on the street. Guess it depends on what you want. If the cam profile moved the power band over more, you'd have higher peak rwhp but then you would lose some low end. IDK. What intake are you running? Your sig says its a 98, but I assume you are running a PI intake.

[ARCANGL]

i think thats a safe bet with PI heads.

but i wonder what his other bolt-ons are... like tb/plenum. Also notice he's on shorties not LT's which is hurting tq across the board and top end power some.

[D.K]

You've got a problem somewhere. Your HP shouldn't plateau like that. My dyno graph was similar after I installed P/P heads. What valve springs are you running?

[02gtfromky]

seems low to me, with just bolt ons and a mail order tune i put down 279/311

[JoeKelly]

I'm using a PI intake stock 98gt TB and Upper. The valve springs are Pacaloy performance valve springs good to 0.600 lift.....I'm not happy with the outcome of the dyno at all. I feel that I should have much higher HP. As for the sound of the cams they have a little chop to them but the car doesn't sound like its going to tear the would apart, from what i have heard on youtube the VT2's have alot more chop to them...I'm thinking that when they were tuneing the car they tried to calm the cam down which I believe is the reason I'm down on power....Hopefully Nick will chime in on this.

[cinch02]

where in southern indiana are you. im in clarksville. my car with u/d, o-r/x, catback, cai, and a tune put down 270/295

Not dumping my CMS Stage II's quite yet.

[2burnouts]

pushrod power ftw

[ARCANGL]

^^ yea whatever

yea... hope im not regretting here soon. I doubt ill keep the 2P cams long anyways... prob go to something more rev happy since i went edelbrock

damn man, you are crazy!

[ARCANGL]

yea i know... but it really depends on how they act. I def wont be keeping them if they dont perform well with my setup. Thats why i dumped the VT2's

[JoeKelly]

all the KY people who have had thier cars dyno'ed where did ya go?

[ARCANGL]

also... 91 or 93 octane??

speedy dyno in owensboro or lee blankenship in shelbyville.
both really good

Well I have learned in the last year that some dynos read high, some read low, and some read just right. IMHO the dyno at ModularDepot probably reads correct and if anything slightly low.

There is some talk behind the scenes that some dynos and/or their operators are slightly inflating numbers. Reason they would do this: to make a happy customer every time. After paying hundreds for a good dyno run if the numbers are not expected then the customer many times will say the tuner did not do as good as a job. Another reason, the dyno itself is out of calibration. I saw a stock V6 Mustang make 300RWHP at SCT’s dyno when I worked there, we all know that is obviously incorrect.

With this exact combo of Stage 2 heads, cam specs nearly identical to the Stage 2P, no pullies, C&L plenum, and longtubes I have seen a car make 290RWHP through an automatic with an unlocked converter on a Mustang dyno. That would equate to around 300-305RWHP with a 5 speed car. I am now thinking this number is inflated slightly.

Another car with the same Stage 2 heads and the Stage 2.5 cams, same NPI shortblock, longtubes, and zero other bolt ons made 295RWHP *untuned* on another dyno with only 12 degrees of spark, then after tuning only made 288RWHP on ModularDepots dyno (it was 270ish untuned). Customer called me asking why it would lose power, I said most likely it didn’t, but you can get the idea.

After seeing the exact same parts (and cars) make significantly different power numbers at different locations I removed the dyno results section from my website until I could learn what is realistic. On a local Dynojet we started using it appears we maxed out 24lb injectors at 285RWHP and had to go to 30lb injectors (our Stage 1 heads, Stage 2.5P cams, 12:1 compression made 308RWHP on this dyno) This caused a ton of confusion as nobody could believe that 24lb injectors could max out that low. Well who knows what this 285RWHP relates to but IMHO injector size needed is probably a good indicator of how much power you are really making.

Back 3 years ago people were running mid to high 11’s from NA 2V with 270-290RWHP, but today people are making more power according to the dyno and not running any faster. IMHO – use the dyno as a tuning tool and let the track and weight scale show you just how much power you are making. If you want higher dyno numbers go back on a colder day and don’t correct the results (many graphs I have seen this done also).

BTW - not trying to give excuses, just stating what I have been seeing reported back. Same car, different dynos, very different numbers, I even posted a page with some good threads on it.

I have seen up to 10RWHP difference at ~250RWHP between the different correction factors depending on the conditions that day. If you have the raw Winpep files you can download the program to view them with the various correction options.

STD just about always reads higher than SAE for some reason.

You need more cam fa shizna between the intake and the compression.

[ARCANGL]

^^ yea i know... but i already had teh 2P cams when i bought the intake. So i'll give em a whirl till i get notched pistons.

and i dont totally disagree with the long post... different dynoes def read diff. SAE numbers are just about always lower than STD. He's not full bolt-on, yada, yada, yada.

If the car rapes on the street than be happy... the dyno is pretty, the street is the truth.
