Throttle body and plenum modifications should not be taken lightly. Air flow restriction in this area will limit HP potential. Stiegemeier offers port-matching to fully welded and enlarged plenums to deliver all the CFM your throttle body has to offer.
Please Note: OEM throttle bodies have the best drive ability! After-market single-blade types will almost always improve HP and TQ, but usually demand attention from an experienced tuner.

Stiegemeier's Throttle Body and Plenum Repair
* All bench flow data was measured on a Super Flow SF 600.
Bench flow data was measured @ 10" of pressure, final numbers were converted to 28" data via pressure conversion constant of 1.67.
Example of converting 10" data into 28" data: (593.5 cfm x 1.67) = 991 cfm
Throttle Body Flow #s 28 inches

Dragon 1132 cfm
Dragon welded Pl 1283 cfm
All flow numbers on a Super Flow 600 brought to you by Stiegemeier Porting.
This graph shows our latest design for the M112 Cobra Eaton Supercharger the 03 and 04 Cobra mods are: Stiegemeier Stage 5 Combo , Under hood CAI (un-shrouded), 2.76 upper pulley, .100 Idler, Gates Belt K080740, notched tensioner, NGK TR6 plugs gapped @ .038, Cat delete, Jim Stiegemeier SCT 93 Octane Tune., boost was 14#s.
The Horsepower numbers are great, but the Torque numbers speak for there self’s. 503 at 3550 RPM’s , Not much off from a 2# Lower reading. The throttle response noticeably IMPROVED in and out of gear.
Jim Stated it was the strongest upper pulley only Eaton he has ever drove on the Dyno Jet (Jim does the tuning and also drives.)
Everything going out as of mid summer has been a Stage 4+. The Stage 4+ is a great mod at a very moderate price, HP per dollar. The Stiegemeier Stage 5 and 5+ are for those who desire the ULTIMATE Eaton upgrade on Planet Earth!
