Alright, I am getting my Kooks LT with catted x pipe installed on my 05 gt (auto) next week. I am then going to finally get it dynoed....what numbers with the rest of my mods in sig below should I or could I expect to put down. I know it varies by dyno etc...but just ballpark

silverstang06

well, look at my mods, very similar....dyno'ed 331 rwhp/320 tq

cheftjpeck

cool...we will see what my numbers are and how they compare.....your numbers are going to go up quite a bit soon after your SC is installed...

I would say that you should be around 315 or so with simliar tq.

Silverstang, how do you have high flow cats with an O/R X?

silverstang06

Ah ok, I was gonna say lol.. Didnt know if you got an O/R pipe but then customized it by moving the cats further down the line or somethin lol. [8D]

What Dyno was that on? Numbers seem a bit high for CAI and headers, or do you have other mods as well? Just wondering...I'm still working on learning the difference between the Mustang Dyno's and the Dynojet's. Thx...

Yeah, I'm no expert, but don't these numbers seem high?

~250 at the wheels for stock auto + ~25 for CAI/tune + ~20 for headers/midpipe = 295 RWHP?

Plus hp can't be added that way. CAI 25+headers 15+ UDPs 8 does not equal 48hp. It's actually very difficult to determine the true hp gains of mods unless you get on a dyno. Yes, a CAI by itself will give you 20-30rwhp gain with a good tune, but adding headers advertised at 25hp gain will get you about 15-20hps. My list of mods adds up to about 70hp as advertised, when in reality I'm probably sitting at about 305 - 315rwhp, depending on what my stock baseline was.
