Great stock numbers "Dillo Dave". So let's see after conversion to flywheel 275.5 Hp and 324 Tq with a broad curve starting down low and some laugh at us for buying the "underpowered Bullitt"???? I borrow the quote "he who laughs last laughs best" and boy am I ROLMAOL!!!!

looks good Dillo!

thats right at 275 crank hp and 323 crank tourque with a 15% drive loss.

BTW..what kind of oil are using? regular or synthetic?

Right now using Motorcraft dino oil. It's due another change in the next few hundred miles. I think I'll keep putting in Fords dino oil until Mobil 1 comes out, then change to it....

And actually, the guy doing the Dyno says there is closer to an 18% drive train loss in the GT 5 speed, so, if he's right, that gives numbers like 286 HP and 336 TQ......

Concerning drivetrain loss, I too was told 18% by an individual over here but I didn't believe him since nearly everyone else says "about 15%." Any Ford types out there able to tell us for certain just what the drivetrain loss is for a stock Bullitt i.e. stock wheels/tires, driveshaft, and gears?

well, I'm not really sure. 15%? 18%? I guess it doesn't really matter.

The rw number is the most relevant measure no matter how you slice it.

But hey, I like my stock numbers even more with the 18% loss:

291.8 hp (239.3 rwhp)
335.7 tq (275.3 rwtq)

My window sticker said "265 hp". Looks like Ford didn't cheat me one bit.

Thanks for the post Dillo Dave. Those are very refreshing results. I'm looking at that torque curve and it is great! It's really what I feel like I'm getting, too. I really appreciate your post.

Hmmmmmm! So where does that leave me at a miserly 223 HP? I guess the Va. dynos are a bit slow. Will be testing again next week,at the same place,to check a mod.

Might have helped that the place I went has a climate controlled dyno area. They block off 1/2 hour to do each dyno. They warm the engine up to operating temp outside, then pull it in. They then open the hood, hook everything up, and wait about 20 minutes to let the temp stabalize inside again, then do the run. Unfortunately, just before my run one of the guys was rejetting his NOS, and someone left the garage door up. Temp soared to over 85* inside. My run was done at about 80*. Still, I'm pretty satisfied...

The experts who designed the car expected 275+hp. These guys KNOW what they're doing. It was unexpected that the cars they checked where only getting 265hp. Seems to me THAT number might be the misstake! The numbers guys are posting here are not hard to believe; they're actually closer to the original expectations of the engineers!
