Buillitt, is't the tune/cai, gears, or both.

gragra73 · February 23rd, 2008, 05:45 PM

An 08 buillitt will do 0-60 and 1/4 mile about 2 tenths faster than a stock 05-08 GT. What is the main factor? The 3.73 gears, the CAI/tune or a combination of both? Does the 3.73 give it 1 tenth and cai/tune the other tenth. Sorry if this has been posted before.

07stanggt · February 23rd, 2008, 05:53 PM

yes. My car with the same power package they are putting on the bullitt dynoed and 296rwhp, 316rwtq, ford is rating them at 319 but as you can see it is underated

Add the 3.73 gears, i thought the bullitt had 3.55s but you could be right, and there is the difference. And really those things should make it more of a time difference.

06RedfireGT · February 23rd, 2008, 06:00 PM

Another thing is that the magazine drivers has proved to not be the best.

IronStomach · February 23rd, 2008, 07:05 PM

The Bullitt also has a 6500 redline, some of the reviews I've read of recent owners have said that makes a difference in shift points on the 1/4 mile.

It's got a stiffer suspension than a GT (not as stiff as SGT) and apparently the tires help too. And that dash has gotta be good for at least 2/10ths a second. ; )

It's also got a tiny bit less weight - no spare tire.

gragra73 · February 23rd, 2008, 10:32 PM

I never thought of the shift point.

07 STROKER · February 24th, 2008, 12:39 AM

do the bullits have the same cams as a GT....if so would they not have the same power band? what good would a higher redline do for it? maybee im confused.

CobraR · February 24th, 2008, 12:42 AM

the bullits do have the same cam. they just changed tune to raise the redline

07 STROKER · February 24th, 2008, 12:53 AM

so they arent done making power at 6250 ?

IronStomach · February 24th, 2008, 01:32 AM

February '08 issue of Mustang 5.0 dynoed the '08 Bullitt. Power peaked at 5,500rpm and tq peaked at 4,400 rpm. At 6,400 rpms the car was only making 10 less hp than peak, but almost 80 less tq than peak.

What they found on the strip in 1/4 mile testing was interesting. The extended redline meant they didn't need to shift into 4th. They posted a best run (the last run, number 9) of 13.48 at 101.79mph. I don't recall environmental variables other than temp being in the 90's.

07 STROKER · February 24th, 2008, 01:40 AM

okay...but is it just me or is that not a smart idea...to leave it in third out of its peak hp tq range...rather that power shift to 4th and go? i dunno im just rambleing...dont know why u would want to take your cams so far past its peak?

IronStomach · February 24th, 2008, 01:48 AM

I've never drag raced, only power shifted on empty highways... but when you shift up to 4th your rpms drop way below peak output (down to 2k?) check it out next time you shift from near redline from 3rd to 4th. That time spent below peak output doesn't put out as much power as the time spent above peak output.

It's generally understood from the replies I've read on the subject, that if you don't have to shift, you're better off not shifting if time is your goal. An upshift kills time.

07 STROKER · February 24th, 2008, 02:05 AM

Get 4.10s. when i shift my rpms go from 6000 to 4000 right in the meat of my peak tq

IronStomach · February 24th, 2008, 11:35 AM

Argyblargy... damn transmission. I'd love to go out and check those shift points right now... if it wasn't ten feet off the ground with the transmission out of the car. Sniff, sniff. Nice video 07 Procharger, how on earth did you mount the camera?

And yeah, 4.10s are going in immediately after getting a CAI/tuner combo.

The new 08 Bullitts also have a ECu allowing for higher octane. The spark ignition system allows for a higher octane in it. Some people actually think their cars will respond to a higher octane in a GT but it will not. The Bullitt is actually setup for higher octane and you will actually gain power from using it.

gragra73 · February 24th, 2008, 03:36 PM

It seems like it is a combination of many factors, but not a single one i.e. intake, gears, advanced timing make a big difference.

what does the ecu do ....advance the global spark to acomodate the higher octane?
