MAC headers w/D1SC
MAC headers w/D1SC How does everyone like their Mac headers with their ATI kit?
Also did anyone switch from Mac's to LT headers w/3" y-pipe? And if
so how much did you gain in the whole power band? I'm not just interested
in just peak hp & tq. I'm looking for people that switched and made more power thru out the whole powerband.
Thanks

There are not many people running the mac mids they are old school. I do know EPP got almost 700 rwhp and a D1 using short tube headers so you could do the same with the right combo.
Damn 700 horses....I'm only looking for 550rwhp at most because i'll still have
stock bottom end. These are the parts i either have and others i need. Here's the list.
Parts:
Procharger w/D1SC and twin intercoolers
SD Concepts 8-rib belt tensioner
GTP Stage 1.5 6.0 heads with 2.02 intake 1.575 exhaust valves
TR Blower cam
Mac headers or Dynatech Supermaxx headers
Magnaflow muffler
85mm MAF
Stock ported TB
Upgrade to 3.42 gears
Sphon torque arm
Boxed rear control arms
Front upper&lower control arms
Interior gauges
beefed up A4
BMR weld in box subframes
And other stuff that i'll need
Vig.3200

now i wanna install my GTP 6.0 heads and my D1SC/twins kit very soon. And
i was going to just get a set of SuperMaxx's which replaced the FLP's but they cost a lot even though they are stainless, and i can get a new set of
Mac's with y-pipe both ceramic coated for half the price of SuperMaxx's.
And the money i save on the Mac's i can put into the SD Concepts 8-rib
tensioner system. Like you said, alot of my buddies had Mac's and they went
fast with them. Thanks i think u helped me make my descision.

Back in the day I switched from MACs (modded collectors) to FLP long tubes with a P1SC and gained absolutely nothing anywhere. Granted it wasnt huge power and had a stock engine but it was still a 10 second car.
The MACs are pretty decent headers for an FI car really until you start getting into bigger power/RPM.

I am going to switch mine out here soon but I did put down 500rwhp/490rwtq on EPP's dyno with my MAC/Ory stuff. That was with a D1SC at 6.5psi. I am going to a 6.0l and pushing more boost, that is the reason for the change.

Thanks KP and ChevyChad...Looks like i can't go wrong with the Mac's and off road y-pipe.I'll take a dremel to the primaries to open them up alittle. Plus i can use
the money that i'll save going to the Mac's over the LT's for upgraded parts.
I know i could make more with LT's but i'm not shooting for that most power
i can make. I'm just shooting for something around 530rwhp to 550rwhp
since i'm still running stock bottom end.

Now my next descision...a cam. I like the TR Blower cam, or MTI's Stealth cams,
and even the SC1 from Speed, Inc. looks promising. Want a good cam that will
go with the GTP 6.0 heads. I think the intake runners are 215cfm or 220cfm...
i've had them awhile and i don't remember their size

i've had them awhile and i don't remember their size
with the GT2-3 cam, or the GT7 cam, and the TR Blower cam. I ran
a small cam in my T/A and i loved the torque it made. Just for ease of
tuning i'm looking at either one of the Lingenfelter cams or TR's cam.
The SC2 looks like a ordinary N/A cam. The other choices i listed seem
built more for FI.
