Looking for next mod
Hi ev1! I was looking around trying to decide what my next piece would be and I wondered if anyone has tried the 25% underdrive pulleys or the ported throttle bodies.
Modern Muscle CNC Ported High Velocity Throttle Body, 5.7L & 6.1L HEMI Engines
SKU: MMHVTB
Modern Muscle's new 5-angle CNC Ported High Velocity HEMI Throttle Body was developed to help increase the flow of air through the stock intake manifolds of the new HEMI engines. AND IT WORKS! The stock 80mm throttle body has shown on many applications to be a restriction on these engines but with Modern Muscles new venturi-like design, airflow through the stock throttle body has been increased allowing even more power while being a direct bolt-on part.
Applications:
2005+ Chrysler 300C, 5.7L & 6.1L
2005+ Dodge Magnum, 5.7L & 6.1L
2006+ Dodge Charger, 5.7L & 6.1L
2006+ Jeep Grand Cherokee, 6.1L
2008+ Dodge Challenger, 6.1L
SLP Harmonic Balancer & Underdrive Pulley, 2005-‘08 5.7L & 6.1L SRT-8 Dodge Magnum/Charger/Challenger/300C (incl. Jeep SRT-8 Grand Cherokee)
SKU: 100235
New 25% underdrive balancer from SLP incorporates a number of high quality features you won't find on any other aftermarket unit and makes up to 9 additional rear wheel horsepower and 10 ft-lbs of rear wheel torque over the stock crankshaft pulley. Pulley features are a pair of extra tall belt retention walls that eliminate the belt slippage issues common with other balancers. Other unique design strengths include a 100% steel construction (other brands use aluminum), integral timing marks and built in puller mounting threads. Includes detailed installation instructions.
Applications:
2006-2008 5.7L Dodge Charger R/T
2005-2008 5.7L Dodge Magnum R/T
2005-2008 5.7L Chrysler 300C
2008-2008 6.1L Dodge Challenger
2006-2008 6.1L Dodge Charger SRT-8
2006-2008 6.1L Dodge Magnum SRT-8
2006-2008 6.1L Chrysler 300C SRT-8
2006-2008 6.1L Jeep Grand Cherokee SRT-8
Features:
Up to 9 Rear Wheel Horsepower Increase
Up to 10 ft-lbs. Rear Wheel Torque Increase
Extra-tall belt-retention "walls"-no more thrown belts!
100% steel construction
Lighter than the stock balancer
Integral timing marks and puller-mounting threads
Does not cause false knock retard or erratic power-curve dips
Note: Requires new belt - See Related Products Below For Link To Replacement Belt.
Does anyone know if these throw codes? Both parts are stocked at HHP. Thanks -Rob

Personally I haven't worked with the ported TB nor Underdrive Pulley.
From what I hear both are good mods.
A local guy is going to port my TB... hopefully next week. The Underdrive Pully is a sure 8-10 hp but takes a bit more work (I would pull the front fascia, drop radiator…).
