ok so today i went to a local dyno its a mustang dyno and its off by like 20% or so everyone says its not the greatest dyno in the area but the only one i could make an appointment for but i made 270hp and 288 tq is that bad numbers with my mods which are

sct2 programmer, mac fenderwell intake,accufab 70mmtb an plenium, 1,5'' intake spacer, bbk u/d pullies, ford racing shorty headers, magnaflow catted xpipe, slp loudmouth catback, 4.10s.
bad numbers or good numbers?


also i have waiting to install are crower stg 2 cams with patriot spring kit and a motoblue bolt in cam gear kit how much do you guys think i will be looking at gaining in hp after they are installed?

 

oh ihave a 2001 mustang gt, auto (forgot to mention)

 

Those are good STD numbers. What are the SAE numbers?

 

Those are not bad numbers considering a stock GT only had 265HP at the crank

 

Autos put out around 220rwhp stock on a Dynojet, that would be a better comparison then comparing his dyno numbers to stock rated crank #'s.

 

I'm saying those are good numbers considering a stock car only pumps out 265HP at the crank OR 225RWHP

 

those cams should definately add you some power...plan on doing any work to your heads?

 

i wasnt really planning on doing anything to the heads right now, but the bullit puts out 265 at the crank a regular gt only puts out 260 but on a dyno wouldnt it be like 210 or something on a stock car ? the guy at the dyno had me do second gear pulls i have a b an m hammer shifter an he had me leave it in second for the hp results i didnt understand that so if i put out those numbers at the wheels how much would i be lookin at the crank? isnt it more at the crank i get so confused sometimes with dyno numbers to the wheels crank etc

 

i felt pretty good bout those numbers from what i see people putting down im gunna try an go to a good dyno instead of this one once i get an appointment but after the dyno i raced some kid in a new sti with exhaust an some other stuff an beat him pretty good so my numbers are ok is what you guys are saying but at least i can still slay imports lol

 

those are great numbers... quit yer sniveling. It is not possible for a dyno to be off by 20%.

Factory ratings are BS... Ford has been stung by over rating their engines in the past so now they're underrating them. Cams will make you a good bit more. Be happy.

 

Thats wrong, he doesnt know what hes doing. Many tuners dont know WTF to do when it comes to autos. They need to be locked up in 3rd, you do that with the SCT software. Your numbers arent right.

 

how can i be locked in third with an auto i mean i have the b an m which has 1, 2, then drive ? j/w and would my numbers be more or less than what they are? what do you think my numbers should be around?

 

by turning off the OD button?

SAE is a correction factor. It adjusts for weather so ideally your numbers should even out (for the most part) from STD to SAE correction factors... not identical but VERY close.

Normal numbers for the mods you have is 230-260hp and a little more tq... like 280-290. A factory freak with 270 on your mods isn't unthinkable. I'd like to see a backup run in 3rd for confirmation though.
