a while back i dyno'd my mustang, the more i think about it i think my #'s were low. the guy's at the dyno (dynojet) said the #'s are going to be low on their dyno compared to other dyno's. i will probably re-dyno soon to see what the outcome is. i see guys with same mods make more than what my #'s show, and guys with less mods make what i did. it was like 103* inside the shop, one of the more humid days of the year, and i drove 3 hrs there, then they immediately strapped it to the rollers. those #"s make me hate this car even more

You of all guys should know it isnt about the hp numbers. . .

[SWEET2KSTANG]

i know, but its just disappointing

dyno's are a tuning tool, alot of people are so fixed on HP numbers they fail to relise that a real car has a usable power band and good TQ, heat plays a large factor in final numbers. and every dyno reads different. I tuned a built 03 cobra running a 78MM turbo and a built motor on 22PSI and it made 880WHP. he went to a dyno day a few weeks later and put down only 750WHP, everyone was like WFT??? just so happend it was wicked humid out, temps were well over 10deg's hotter and the dyno is well known for reading super low. the owner knew the car flat out hauls and is 100% happy with the setup so the numbers didnt bother him. well others though different ans set up a race between a car that put down the exact same numbers(750) as him a few days ago on a diff dyno. End result was my customer destroyed the other car and then some. all while the other people bashed the numbers it put down for what was done to it...

As long as you know that car performs the way you want it to dont worry about some number some computer tells you

i hold the bar high on this car. i personally dont like it, but after owning this mustang i give them a lot more respect. i wasnt looking for some off the wall hp#, but was looking for 13-15 more hp n/a. the weather has cooled and the humidity is down, i think i will be able to get what i was expecting, maybe a little more. but it does run decent for the little power it does put down. and now the ignition is on, it revs a higher and a lot better 4500+ rpm's. and the 422ft=lbs is nice. i will up the shot soon and see what my motor will handle

try doing cams in a mustang with full bolt-on and only getting 255rwhp

[Blackblurr_00GT]

yes thats what happend to me but the car does haul ass. Its funny though i'v beat cars that i probly shouldent have. could be driver or my car could just be faster idk.

god i guess i am not getting cams now! i think they lower your numbers the real question is what do you run in the 1/4

Are those guys pulling 12.01@114? I think its safe to say that you can get 11s and a 11second car is a 11 second car.

+1 I had an newb tuner tell me that turning adaptive learning on causes less hp. I said no it doesn't, unless you butchered the tune and set everything up wrong. Then i find out that there was only a 10hp difference on a different day. I asked him if he knew the ECT, IAT, Timing curve, Air temp and humidity, etc (nope). He had no idea that small variations can cause different readings. Something small that many people can overlook is the oil temp and dif fluid temps. Those can have fairly large effects on the hp. With the right combination of temps you could easily see 10% differences in hp from best to worst.

ding dng ding

i am still trying to find another dyno shop that is fairly close and dont charge out the wazoo for a few pulls

[Trick Tuners]

Just go back on a cool day with low humidity (in the morning), let the car cool for 1hr + before the dyno with the hood open and a fan on it and you will probably see 20+ hp. Dynojets are inertia dynos and there is little that can be done to make them read low if the LC is not used.

[SWEET2KSTANG]

the dyno is a dynojet 248c according to their website.

At the end of every dyno tune I do, I print out 2 charts. 1 chart that has real world corrections, such as temp,baro,humidity and so on. I do not skew my number at all!!! the other sheet I offer to the the customer as a bragging chart, which will be uncorrected. But I still give him the 1st chart with corrections and load factors. I can make a 500WHP car read 550WHP. its all in who and how they set the dyno up. Load type dyno's will always read low, they are a real tuning tool in my opinion, considering tuning timing on a non-load or "intertia" dyno is much more time consuming then on a load type dyno. The increase in time also creates heat soak, thus giving you the low number read-outs. the best thing to do is jump around from dyno to dyno on dyno days. depending on who set the dyno up you can sometimes notice anywhere from 6%-18% fluctuation from dyno to dyno. Thus the reason I tell all my customers not to guestamate HP using another car as a reference. My goal when tuning on a dyno is solid A/F and perfect timing maps, as well as a usable power band. As long as your motor is in good shape, and your tuner knows what he is doing. your car will/should make the power it was built to make. It might now show it on a dyno like you wanted, but it will prove it on the streets. Personally I try and only run on Mustang dyno's as their load design is top notch!

[SWEET2KSTANG]

me and doc has done all the tuning on the car, and we think the heat and humidity killed the hp mark i was looking for. there is a mustang dyno not too far from here, but they are pretty expensive. i am looking around a little more for another dyno, but everything seems to be a pretty good drive away.

That sucks, there are quite a few dyno's in our local area, and most of them will let you do 3 pulls W/ A/F for under $60. evry shop has a different dyno too. Mustang, Dynojet, land&lsea its cool, I guess you have a choice as to the dyno selection

[SWEET2KSTANG]

we have a crappy dyno jet locally, they charge something like $85 for 3 pulls, and another 5 for printouts and charge also for afr readings if i remember right. plus it takes forever to even try to get in there. these guys told my neighbor with a 97 v6 camaro with cai and chokemast muffler, 277/25x. then the next closest place is 75 for 2 pulls, another 10 with afr readings, etc. then i have to drive a couple hours minimum to the next closest.
