Forced Induction SystemsDetailed discussions regarding cold-air intake systens, superchargers, turbo chargers, and other induction systems for your vehicle.
This is a discussion thread titled "JBA Headers.", within the Forced Induction Systems forum, part of the Technical & Vehicle Assistance Forums category.
Just so you guys realize, The DT's give power all the way through. For light to light or drag racing you want power in the low to mid to give you the holeshot. That is why racers put low gears in. To give them the takeoff advantage. If they wanted top end then they would put in 3.00 gears to give them max speed but it would take awhile to get there. These engines run best at midrange to the bottom of the topend but you have to have power to get there.
Just got off the phone with JBA corporate who states their headers are 20hp at the wheels and 32 pounds of tq. I am still leaning towards DT because their customer service seems to be a tad bit better also they have offered to do a head to head competition that JBA backed away from.
Also I dont know if this means anything but JBA said they had to do their dyno pull in 3rd gear due to the truck being automatic or something like that and that they would have the graph up on their website soon.
I know there was a big post about this earlier and it seems that in a race the only time u would be at 3krpms is in first gear where im spinning all the time as it is. the six speed makes gear changes usally not occur under 4krpms so thats y im thinking the jba's r for me, although i appreciate the quality and reputation of your product nick, i just think i need the top end power more than somebody that would do alot of towing. while i think the DT headers are a great product i just dont think they are for me in my application

I don't know how the JBA's perform on the 5.7 ,but I had a pair on my 4.7 and the DT's that I just installed lined up perfectly wokman ship was top notch. To me the install was easier than my 4.7 JBA install. It took 3.5 hours start to finish with two people. Let me say I am not affiliated in any way with DT but my personnal opinion is these headers pull from down low all the way through. The reason I went with DT is because I wasn't impressed with my JBA's on my 2000 Tundra. I have the ceramic coated headers on for about a month. Their is no discoloration on the headers it looks just like it came out of the box.
I know that. Atleast the board will have an unbiased report done. There is a member down in Sandiego that has stepped up to pay for dyno time in exchange for an install. I am working on getting it approved by the people in charge.
I am putting in a Call to JBA tomorrow with a copy of these boards to see if they want to play ball but something tells me they dont want their headers any where near a dyno that isn't theirs.
I have a set of JBA headers sitting in my RCSB right now in San Diego, does anyone know a place where i could get it put on a dyno and see before and afters at a reasonable price.
What Part of San Diego? I am In La Mesa so Santee is pretty close and thats the dyno shop I am planning on taking the Thorley headers I got a quote of $104 for 2 back to back runs.
Since JBA isnt going to step up maybe you,me,and Thorley can make it happen by ourselves. You and I can take our 2 trucks there before and after???????
