They're also installing a trans cooler. I'm going to the MMRA race in Bradenton to possibly pick up some new mods tomorrow. UPR has some drag springs and possibly more I'm considering.
Solid black bullitt 20x8.5's and 20x10's are also on the way with nitto invos..

lets try an actual 5.0L mustang magazine article(for 05-10 mustangs):

http://www.mustang50magazine.com/tec...ooker_jba.html

JBA gains, 3500 RPM 9.3, 4000 9.9, 4500 13.0 5000 14.77, 5500 17.41, 6000 26.3, 17.82 average gain
Kooks, 3500 RPM 7.31, 4000 9.06, 4500, 12.82, 5000 19.39 5500 19.11, 6000 40.76, 23.59 average gain.

The important part is the 4500-6000 rpm range since thats where you are when racing. Kooks makes the best headers on 05-10 mustangs and I believe for 11-12 as well, although there isn't a comparison like this out yet for the new 5.0.



for the rest ill list min/max gains and avgs
jba, 9.3 min, 26.3 max, 17.82 average
Bassani, 8.41 min 33 max, 17.39 average
BBK, 7.17 min, 33.61 max, 17.39 average
hooker 5.61 min, 28.08 max, 14.57 average
kooks, 7.31 min, 40.67 max, 23.59 average
mac, 6.43 min, 42.13 max, 22.52 average
Stainless works, -11 min, 35 max, 12.78 average

I have over 3,000 posts and a member for over 4 years.. i've done research. as far as peak power jba is the least gains, average worst are hooker though. and I'm not including that stainless works header issue, they said they had to cut stuff and no mid pipe so they had to fabricate something? so something wasn't right with the kit they received, those numbers seem way off although still much better peak numbers than JBA. on the 11-12 mustangs people report stainless works as good fit/finish and good gains.

also note that those mac's that performed well are their expensive mac ceramic line, not their cheap $600 set.

So what you are saying is that a supercharged 4.6L 3v mustang made more rwhp with larger diameter Longtubes tubes? Test the 1 7/8" JBA LT's against any other 1 7/8" Headers and lets see the difference.

I thought EVERYONE knew that larger diameter headers will make more RWHP. With a blower for sure!

Just wanted to share some great news to Mustang members. BTW I have used Kooks and others before but the difference in price is not worth it in my pocket book.

The macs and the stainless works were 1 3/4, so an extra 1/8. The rest were all 1 5/8
