Dyno Numbers

[En4cer71]

How does 271RWHP and 299 TQ sound. Only mods are k&N cd air, 410s and tune.

[ImpalaSlayer]

sounds high

[En4cer71]

Good! Lol.

[dohc324ci]

Good numbers!

SAE or STD#s? Dyno or mail order tune?

[En4cer71]

SCT tune tweaked on dyno.

[En4cer71]

Clarify that. SAE or STD?

Clarify that. SAE or STD?

There are different scales that can be used, some read higher than others STD is always higher than SAE (which is the number people usually think of when quoting) So some dyno places will run the numbers in STD to make the results look more impressive, also there is a trick with the smoothing which can add a bit of hp on the graph.

Well sumpthin' ain't right, HP & TQ figures are SUPPOSED to be equal at 5250 RPM...

Yep STD scale and smoothing 5, kinda figured. That's at least 10 - 15hp more than it would say using SAE, and then a couple easy for the smoothing. Sorry. prob really 250some.

^^that's only because the scale total for the tq isn't the same as the hp, not a big deal, if the two had the same max they would cross, kinda silly not to just make it the same, but such is life

[En4cer71]

I feel cheated. Can they correct it if they saved the file or would they need to dyno again?

they should be able to adjust it on the computer and print you a new sheet so long as they saved it.

[En4cer71]

Well, sent them emailing asking them for the numbers without smoothing and on sae scale. Let's see what happens. So, how do the numbers look? Low, avg, high?

[dohc324ci]

^^Nah dont worry lots of people do this; they can convert it for you as long as they saved it. or:

STD numbers = SAE when adjusted approx 2% - 4% lower. Multiply STD numbers by .98 -.96 to get SAE

If my math is right 260rw/287tq-265rw/293tq not bad still.

more likey its int he 260 range and 280 range

think i made 265/284 with tune and cai.

[RR|Suki]

in that power range usually 10hp for STD instead of SAE and a little for the smoothing, maybe a couple. That's why I said 250some since it was at 271. Not a big deal, just a silly way to make the numbers look inflated compared to others quoting SAE.

Where in The MIA did you go?

[En4cer71]

Mustang Specialties. PM me if you have any good places down here for stuff. (audio especially)

[musclemerc]

^^ Tim (the owner) is a good guy call him directly and ask.

Who was the dyno operator?

[En4cer71]

John Rollins. They were both good people.

[RacerX]

Here's an example btw. See if they'll give you your drf files and you can see them in winpep7.

[En4cer71]

How come you have two set of numbers on each chart? Blue and red? Is that before and after? Difference is not too bad on the two scales. >10

[RacerX]

I have all my dyno files since I bought the car. Downloaded Winpep7 so I could manage all the runs (add different runs to a single graph, etc.) and print them (free progie btw). The red is from the original engine with 118k on it and a few mods. The blue is the new forged sb with everything in my sig. Those are the best runs of both at the time. It has MORE hp/tq now. Been tuning it myself. ;)

[ctrlraven]

My last dyno was 289hp/313tq on STD. So lets say 280hp/300tq, running 13.63 with the trans tune being way off. Hate to see what I do when I get 300hp and trans tune being on point. lol

[RacerX]

That'll be nice to see in my mirror... :D

Currently the only thing you see in your mirror is nothing cause I am in front of you #94. :lol:

Seasoned veteran engine and no bottle feeding here. :P

[RacerX]

Hehe! (hate how that always looks like heehee! :D). No bottle against fellow na cars and granted, new forged block with ported heads and 98 cams may not be considered equal, but, I gots me sum nu sticky shooz!!! Muahahaha!!!:neener:

[BODYMAN]

That'll be nice to see in my mirror... :D

Were do you expect to be in the 1/4 with new goods? Less the bottle

[RacerX]

Realistically, about 13.5/13.4 NA and upper 11's with the 200 shot.

Stll be very nice for a N/A , what was Cruztaker running N/A If I remeber he was low to mid 13's looking at our cars going mid 13 no power adder is dam good and would still smoke a STK stang

[Pops]

About 13.24 for Cruztaker.

[En4cer71]

That's impressive. Not sure where to go next. Pullies are coming in and have the 410s, tune and K&N. Wanna stay N/A for a while.

That'll change; ask me how I know... ;)

[En4cer71]

Oh, I don't have to ask. I want it, just wanna stay put for a little longer. Lol

[Cobra25]

Sounds like some good numbers for the mods you listed. Congrats !
