HEy im new to the forums, i have a 1996 Svt cobra, im bringing it to the dyno next week and was wondering how much rwhp i should expect to get, i only have a these modes: k&N filter o/r h-pipe, flowmaster mufflers, what should i expect to get........Thanx everyone

i would say somewhere around 260-275 rwhp SAE but our dyno is low compared to others.

With an O/R H pipe you should see some better numbers... Stock I've mostly seen those things at 260 RWHP STD... You should be a bit higher with that O/R pipe.

Don't count on it, if it is stock you can plan on losing power with an O/R pipe no back pressure, Mike. If you think it's a crock, go dyno it, and then tell me what it makes. I've been playing with these things, for forty years. I had a Bassani O/R X pipe on my 96 when I got it. The first thing I did was put a set of free flowing cats on, and it ran 100% better, No Sh-t, Mike.

How did it do?
And go by SAE not STD, STD reads higher and I never go by that.
Also mustang dyno or dynojet?
