Bullitt Dyno Results

[Frazier]

The numbers are right on the mark for an 18% drivetrain loss (all stock) but I was a little dissapointed that they weren't better since alot of other bullitts are getting about 15 more hp and tq.

Mod plans are magnaflow x-pipe, magnapack cat-back, mass air system. Have thought about going with longtubes but not sure if the cost for parts and labor are worth it.

I am hoping to have a supercharger by next summer.

Any opinions/experience on mods - please reply...

Those numbers *do* seem low... especially from a Dynojet.

Are you sure your Bullitt is running right? A/F seems damned rich for N/A (everywhere except between 3.25 & 4.25 PRM), which could cause the lower power.

And how come your HP graph shows clearly LESS than 200 HP peak, but the numbers superimposed on it indicate higher?

Something is definitely not right. What mods do you have?

No mods.

The graphs weren't showing right all day. Everyones printout was wrong. Took a look at the laptop while they were doing other pulls and the software showed the graph correctly, just didn't print out correctly. The guys said that the #'s were right though. They explained that the a/f was a bit rich from after 4000 rpm's. The a/f on the first run didn't start reading right off which is the cause of the drop in.

There were a couple fox cars there that only had a cat-back and they pulled about 205-212 hp. A couple 99-up GT's with an x/h pipe, cat-back, and maf pulled about 225-235.

numbers do seem low. My 04GT with drop in filter and bbk hiflow H pipe netted 229rwhp and 270tq SAE corrected. My a/f was rediculously fat 11.4-11.8 throughout.
