Bullitt Swap Results

Slapyo · Aug 9, 2005

BEFORE: 239 RQHP / 283 RWTQ
13.85 1/4 Mile

AFTER: 252.3 RWHP / 288.1 RWTQ
13.60 1/4 Mile

Those numbers were done on a Mustang Dyno.

The problem we ran into is that it's sucking in alot of air, but the stock GT exhaust isn't pushing it out fast enough. I need to get an exhaust for it now to help with the increase of air coming in.

yes, wondering the same thing.... and is this just with a new MAF or what?

my question would be why get a extrude honed bullitt intake on a stock gt? Did you purchase from a friend or something? I like the intake but you may have been better off using that money on other things then getting an intake later after you have the mods to support it. It is your car and if you like it thats all that matters.

Updated my first post to show before and after.

I got everything I needed for the Bullitt Intake swap very very cheap.

How does the car feel? Any big SOTP gains? I know the bullit intake alters the torque curve.

Slapyo · Aug 9, 2005

It does feel better. Now we can scratch the tires going into 3rd gear. The 1/4 mile time dropped. Actually let me post that under the original post as well. It pulls strong though.

i would love to have a bullit intake manifold...that would help me so much right now....good numbers for n/a

AirWolf87 · Aug 9, 2005

sounds like you got the same gains I did with my PI intake swap. pretty cool. I was thinking about oing with a bullit intake, but i worried about it not fitting as good since it is alluminum.

Justin03GT · Aug 9, 2005

i want a bullit intake not for the power, but because with nitrous its A LOT harder to blow up the metal intake than our cheap plastic one...,.

Do you have the before and after dyno graphs? Id like to see the curves, i'm in the process of doing a p&p headswap/vt stage 1 cams and the bullitt intake was curious how the curves change over stock, but it definilty looks like that intake helped you out great results.

I forgot to bring over the printer driver last night. I am going to go over there tonight with the printer driver so we can print the results. I will post a new graph when I get it tonight. For an old graph you can look at the one I have on my cardomain site. Link is in my signature.

How much did the swap cost you total Slapyo? I've heard it's like 1,500.

If that's the case, it makes more sence to me to go with the Fox Lake P-51 Intake.

I'm not ripping on you either bud.

Slapyo · Aug 9, 2005

Well some Ford dealers sell the complete kit and I heard it was like $3000+ for the kit. I got all the Bullitt stuff from a friend for $1800 and then the Extrudehone, Accufab TB, SCT Chip and minor parts here and there needed to finish the swap was another $1800. Plus it was dyno tuned as well and that's pretty expensive. We spent from 5pm yesterday till about 10pm.

I only spent $1800 on it because the Bullitt stuff was a Christmas present from my parents.

It's all time and patience man, you can find em used on modulardepot for 800-900 for all the stuff you need. Me personally I bought the upper and lower and the upper plenum and some of the gaskets brand new in the box for $465 shipped, and then I paid another 300 or so in install parts, some stuff I bought used like a cobra throttle body and cobra intake tube and a used continental alternator.

madmatt · Aug 9, 2005

Man, 3600 bucks for an intake and tune though, come on man, thats a mongoose kit. But I guess its all about what you want to do.

Heh I would rather have gone with a supercharger ... but I had to work with what I was given and that was the intake.

I see. Wow. That's a lot of cabbage for only 13 RWHP. Again I'm not riping on you, but for what you paid for that the P-51 swap makes more sence to me and you'd have money left over.

For the price difference of the P-51 kit, and to get more power out of it than the Bullitt intake swap, the Bullitt swap doesn't make any sence to me and isn't even an option for me. Yeah the Bullitt intake looks good, and some people don't like the way the P-51 intake looks (I'm not one of them), but so what. Besides the fact that the P-51 kit costs less and makes more power N/A, the real gains you'll see from the P-51 once you slap are Centrifigual on it.

Again I'm not trying to rip on anyone here, just trying to say what's more logical to me.

Slapyo · Aug 9, 2005

Heh yup yup. I know what you're sayin. But it was given to me. I spent $1800 myself. I'm saving up for the Bassani exhaust next ... so we'll see what kind of power that opens up since it will be less restrictive than the stock exhaust.

the composite intake isnt that cheap. They are pretty strong and lots of cars, icluding LS1s, use them. Its just that the bullit has a better design. If you run enough nitrous to blow your intake, then the rest of the engine wont be doing too good. the only occasions that ive heard of this happening is when a solenoid leaks and pools nitrous in the intake, either way, this will damage both intakes.
