Do you have the bolts for it?

Oh and I ordered it for a 04 Mach 1 Stang. There the same engines from heads to pan. Because they didn't have one listed for a MM

depends on supercharger set up..big whipple for example needs bigger tb than this and can get solid oval opening shape and not twin bore. This fits stock, trilogy, prolly vortech. Not sure if it fits eaton swap, may need a different model. Stock tb can be used on trilogy, vortech, not positive on an eaton swap
Okay, I may just wait to see what I end up doing. Probably doing an eaton but the guy who is doing the work actually is friends with a Procharger rep and may be able to get me a free or severely discounted procharger SC. But nothing is decided now. Thanks for the info!

somebody with an eaton will know. it may need a cobra one and not the mach 1 since the intake is on the pass.side. I have one on my trilogy car..They tend to add a little better throttle response compared to stock..gains in power, prolly not noticeable.
Horsepower can be restricted by orifice size. See also "nascar restrictor plate racing".
When throttle-plate restricting the american iron SBF cars for 300rwhp maximum (checked on their dyno), we use a SINGLE 50-60mm orifice between the throttle body and intake; sized/selected depending on the exact cam used. So, if you ask me, a Marauder already has a very over-sized throttle body. On an engine that is pulling atmospheric air through a twin orifice throttle body, I'd say the stocker gets restrictive somewhere around 500-600rwhp. If you want to know for sure, measure intake manifold vacuum at WOT. If it's zero; there's no throttle body restriction.
If you're a centrifugal or turbo guy providing pressurized air, you'll probably never find the limit of the stock throttle body. My blown/injected 385 series ford used a donor Marauder throttle body and I blew through it with a Vortech V7-JT. It made 1080 to the wheels. I changed it to an Accufab giant oval Lightning throttle body and that resulted in ZERO gains. In fact, I was never able to repeat the 1080 number; the best I ever saw was 1030. I sold the expensive Accufab unit to a lightning guy.

tb are the same as a Mach 1 and The Marauder I've done 3 eaton swaps and on all 3 I used the stock Marauder throttle body it fits with no problem.

And with all that said I've heard there is little to no gains with a twin blade throttle body unless it's on a boosted car. if it were me I would go with the single blade just my opinion to each his own.

single blade wont work with trilogy plenum, has bridge or web in middle so blade would hit it.

STILL N/A
Because everybody seems to have an opinion about this throttle body that I've offered for sale....
I thought that I would post this, from the SVT Performance website's discussion on the AccuFab twin 60mm throttle body being used on the Mach 1 Mustang.
(the same throttle body and the same engine as a Marauder)
George Klass's (from AccuFab) comments:
Let's talk about the 99-01 Cobra TB (also fit's the Mach 1). As many of you probably know, most of our TB's are single blade units. Unfortunately, a single blade unit won't work on the 99-01 Cobra because (as was pointed out above) the IAC port is in the way, and the center "bridge" would have needed to be removed, the car would have idled at about 4000 RPM, not a good idea. Removing the bridge on the 96-98 Cobra intake is not a problem as the IAC port is not disrupted.
Anyway, we learned alot while developing this dual-blade unit (took almost a year and 8 different versions, all tested on our flow bench).
We found out that "the size of the hole", usually measured in MM) is not as important as the area IN FRONT of the blades.
As someone above mentioned, it's not the size of the blades on the OEM TB that is the problem.
The problem in airflow is the air seperation that takes place on the OEM unit, in front of the blades.
This is what restricts the CFM, not the size of the blades.
I'm not going to bore you with these details, especially not on a Monday, so you will just need to trust me a little in this area.
I can just say that we flow test EVERBODY's throttle bodies, not just ours. We also dyno test them all, on Westech's engine or chassis dyno.
If we can't show more HP than stock, we won't offer it (which is why we do not sell TB's for the 94-95 Mustangs).
The new TB for the 99-01 Cobra has just been dyno tested, back to back with the OEM unit, and is worth about 9-10 more HP on a dead stock engine.
Slightly more if you have increased initial airflow with a cold air kit, better filter, etc.
This test will be in an upcoming MM&FF magazine since it was done by Richard Holdner.
As most of you know, Accufab is down the street from Westech and we are on the dyno 3 to 4 days a week testing some damn thing or other.
If you have questions you can email me anytime at accufab1@aol.com or call me at Accufab, (909) 930-1751. Cheers.
There is alot more to building a throttle body than just making the blades (and hole) larger.
Airflow is everything. Bigger holes are nothing.
We were just lucky before with our Mustang 5.0 TB's. With those units, bigger holes meant increased airflow. We go up to 105MM TB's for the 5.0.
The 105MM TB flows 1550 CFM.
Just to keep everything relative, the 03-04 Accufab TB's (same for the Lightnings and the "big" units for the 96-98) flow 1696 CFM.
The 99-01 Accufab TB's will flow about 1284 CFM. OEM is about 1089 CFM.
Like I said, the dual blade units for the 99-01 will not make a big increase but you will feel it in the seat of the pants.

yes you're correct it wouldn't work with a trilogy but it will work on an Eaton swap with the plenum elbow whatever you call it. And another question I'm curious about is how much horsepower would that add on an Eaton swap single blade with an elbow that's been ported from accufab?
fastblackmerc
Everything Marauder, LEDs & HI
IMHO... the throttle response alone is worth it.
Sully008
Hammering out a few details...
Not to derail the thread, but I'm using a single blade Accufab on my Trilogy with no problems. Bolted right on.:dunno:
Good luck with sale, op. Nice price!
