ya the car is putting out 460 rear wheel hp....with just the smaller pulley, cold air intake, and cat-back exhaust, number sound about right for the mods right?

 

a wee high, but i guess its possible.

most bolt on cobras make 440-450 with your average bolt ons...

 

 

I made 465 rwhp with similar bolt-ons....check my sig...

 

A couple of comments. First, if you have a newly acquired '03/'04 Cobra you should always have the tune checked, regardless of whether the previous owner assures you that the tune is fine. It is best to not assume anything. Either go to a local dyno and have your A/F checked or use a wide band. Second, it is very smart to have the tune checked by a good tuner, and adjustments made where and if necessary. Many used Terminators come with excellent tunes. Others might not. Again, never assume anything.

As far as your numbers with the 2.80 pulley, you're right at where I'd expect you to be. With a 2.90 upper, intake, exhaust, Accufab TB/plenum and Amazon tune (excellent by the way) I made 457rwhp and 480rwtq (SAE). That was a bit on the high side of the averages. A 2.80 upper with other similar mods would likely be in the 460-470rwhp range with a similar tune.

 

what does a/f mean? you think i should get a compression test done?

 

A/F = Air/Fuel

I would get a compression test done and get the car put on a dyno asap so you know everything is good with the tune.
