It's nice to see we're getting lots of cars out into the hands of the buying public! Along with that comes the excitement of getting on a dyno.
It seems we're getting an awful lot of posts regarding dyno numbers and I think it's in everyone's best interest to keep these consolidated.
So future dyno results should be posted here. If they are posted to a new thread I'll let them bask in their glory for a few days and then move them in here,
saleen dynoed my shelby.there # on the first run was 460-rear wheel,and as the roots blower tended to heat up it lost between 10/20-rear wheel Hp.So they up graded the roots blower to a saleen twin screw blower. I'm waitting on the new #s.
481 rwhp & 472 rwtq BONE STOCK, inside for #'s w/ JLT CAI
i brought my bone stock shelby over to RWTD in mobile on saturday and we had scheduled to do a custom tune JLT cai and 2.6 upper w/idler, well the idler was on backorder so it was just the JLT cai and tune. well we strapped the car down and the first run put down 470 & 462, neither of us could believe it so we made another pull and she spit out 481 hp & 472 tq, with NOTHING done except i had already cut off the stock mufflers and replaced with just pipe. i couldn't believe it, we then decided to put just a tune in her and she spit out 496 & 483tq. these numbers were all SAE corrected, hell uncorrected she put out 509 on the stock run. we then put on the JLT CAI, (the blue carbon fiber which looks awesome by the way) then she spit out 522.42 hp and 494.86 tq. James w/ RWTD did all the tuning and really knows what he is doing and took the time to do it right, after the jlt install we made a total of like 6-7 pulls just to make sure the air fuel was spot on and it is 11.8-12.0 across the board. This car is now so much better the throttle response is so much better and just plain hauls ass, can't wait to put on the 2.6 pulley next month. the car would have even made more but at around 5600-5700 we started getting belt slip, the hp curve flattens out and the maf counts started to fall off, so we are going to try and put the idler on with the stock pulley and see what it will do.here are the graphs.i believe this is the most powerful stock shelby to date.
these are the uncorrected numbers, they are just plain crazy
so if i take my cats off, no mufflers, and run no filter just for a dyno run i can get the highest hp stock shelby too
what are you talking about all i did was cut off the mufflers and put straight pipes, everything else was left as it was from the factory.still had filter and cats. there is hardly no gain from axleback exhaust on these cars.

i am sure cutting off the mufflers had some sort of effect on your power output. Stock is stock, and your car wasn't stock. Still sick numbers.

changing mufflers will have little or no effect. taking the mufflers off will make it easier to breathe. the reason race cars do not use mufflers is becuase the muffler will restrict exhaust air flow reducing power. great numbers regardless.
I do not mean to be the ass here,but dynojet has been proven to be higher than anyother dyno out there.I mean any with the rollers,not counting the type that pulls the wheels off.I know this for a fact as I listened into a conversation with a dynojet salesman....He plainly stated "we show higher #'s than superflow,mustang, dynameter and all other roller dynos.We know that higher #'s sell better and we want you to have more customers."
That is my first reason for saying that,my second reason is this......We pulled my car on a dynojet and got 491 corrected rwhp and 480 rwtq,then we pulled it on a superflow and got 444 corrected rwhp and 435 rwtq......This is not an opinion,but a fact as proved on my car....I dont want to be flamed for it ,but that truth is the truth.......so then when we done the stage 2,we got 565 and 560 on dynojet,went back to superflow and got 526 and 517 so there is a big diffrence......This was on the same days,temps,humidity and all conditions/factors were the same......Dynojet is good for bragging rights and thats pretty much it.......So that means by the dynojet #'s I have the highest bone stock/with stock mufflers to date......Dont mean to piss on anyone but this is proven.....

okay well i guess i stand corrected, did you post up any of this info before because i don't remember reading it. i had never heard of a shelby dynoing any higher than like 450 or so. can you post up a pic of your graph for me so i can check it out. i am aware of the differences between the dynoes but it's enough that we argue over correction factors, so to argue over dynoes is getting too much. i guess we can't trust any of them. but i have no choice on which one my tuner decides to use. that must have been?a long day for you to be switching dynoes that much, was it the same shop?
Q1. didnt post before because I wasnt a member when I first done it.
Q2. Yeah I can post a pic,what do you want the dyno sheet? I didnt get a dynop sheet of teh dynojet run,because I was told it was just higher #'s for bragging rights.I do have the prinouts for the superflow,do you want a scan of them?
Q3. Hold on, I dont want to argue with you.but as a fellow GT500 owner,I dont want you misinformed either.That was the reason of my post.I've been told by many people that the dynojet always runs higher.It is not just me saying it.So to prove this "theory" we talked to a rep from dynojet and was told what I mentioned above.Then we dynoed my car with the 2 diffrent softwares(dynojet and superflow)and also had it dynoed at Evolution when some work was performed there ,but it was after the work was done.
Q4. yes it was at the same shop,done with the 2 diffrent softwares loaded....
Now just to prove my intentions were good,You do this.......it will prove I'm not just saying/slinging crap all around.....Go to someone who has mustang dyno or superflow, get you car dynoed there,and if its as high as the dynojet,I'll pay for your dyno session.That will be stone cold proof.You will actually see the diffrence, and its not just to doubt you or your tuner.....I hope there is no hard feelings man, but I was just trying to help ya out a little.
03,You are right.People mostly use dynojet because it is the most popular.I was just trying to let him know that they are off some.Thats it nothing else.And yes they are good #'s, I didnt say they were not, I was just saying they are a little high and not as accurate as most dynos...
wow this thread turned for the worse in a hurry.
Guys, his car put down awsome numbers. Shut the F up and quit whinning and saying yours made more or you know someone that made more.
A dyno is a tool for tuning a car, not bragging rights. The 1/4 is for bragging rights.

no hard feelings,just looking for info myself, and yes i would have liked a pic of your dynojet sheet to compare to mine but since you don't have it i guess that is not possible, i appreciate your info but at the same time would have liked proof.dynojet is the most used from my prospective and i guess they do put out "higher" numbers and maybe that is why because isn't that what we ultimately want and it is repeatable.
I do not mean to be the ass here,but dynojet has been proven to be higher than anyother dyno out there.I mean any with the rollers,not counting the type that pulls the wheels off.I know this for a fact as I listened into a conversation with a dynojet salesman....He plainly stated "we show higher #'s than superflow,mustang, dynameter and all other roller dynos.We know that higher #'s sell better and we want you to have more customers."

1. Bull shit.
2. Wonder why most NASCAR and CART shops use Dynojet?
3. Have you ever heard a salesman that knew the difference between his onw ass and a hole in the ground?
4. These dynos you listed measure dyno in different ways by how they apply resistance. A Dynojet measures HP from the inertia to accelerate a known mass. Do you think a G-Tech works? Ok, it may not be perfect but it's close. It uses the same math equations as a Dynojet. These equations are laws of physics. That's a hell of alot better than "bragging rights". The numbers I see on a Dynojet are right on par for what the cars run on the track. There was a dyno sheet of an 03 Cobra that was put on an engine dyno at the Romeo truck plant at it dynoed 425 HP SAE. Is that anywhere close to the 365 rwhp we are seeing on boenstock 03's. Hum, 365/.85 is, well, 425 HP.
These other dynos are using eddy flow resistance and water type on with starin meters. They all have different conversions. A Mustang Dyno is eddy flow and it's factor is close to 27% so it will dyno less than a Dynojet. They all have different conversions. But, when they are converted they should all be close to the same numbers. All I have to say is NASACAR uses Dynojet.

fears-I will see can I get a dynojet p/o from the tuner...
See in the last few sentences you plainly stated that dynojet throws a higher#.When dynojet is corrected stp or sae it is still higher than the other dynos.You say bs.....are you saying my car didnt do what I say it did?I was right there and seen it.The dynojet puts down a higher # anyway you look at it,and thats what I was saying.And I dont know why they use dynojet,maybe they want to see higher #'s just like everybody else.Maybe they want the highest #'s for the moneyt they have spent.Maybe dynojet has contributed the most money and thats why they use it.But I bet if they used another dyno it would be lower #'s.....
I'm not trying to say my #'s or fears #'s are better ,I was just trying to let him see the diffrences.Yes his #'s are great no doubt,but just like mine or anyone elses,they will show lower on just about all other dynos.That was just what I was trying to say.And I'm not here to argue,but sometimes debating is the only way to learn somewthing that I may or may have not been wrong about....
Explain this to me then,because I dont understand......My car right now puts 565 and 565 on the dyno at Evolution performance, but on a dynojet it puts down 630 and 635......
not calling bs at all just asked/wanted to see the sheet on it, that's all. see if the shop can email it to you, would just like to lay yours over mine to see how it looks in comparison.
Along with that comes the excitement of getting on a dyno.
