Potential HP Gains
5-12 whp (Average seen is 5-8whp)
* Gains will vary greatly due to many factors such as engine health, other modifications, weather conditions, etc. These numbers are estimates and not guaranteed. Our proven dyno numbers can be seen within the product photo's
*Please Note, all orders will usually take 5-10 business days to complete the work and ship the item.
Our HalferLand Performance "Venturi" Stage 3 PnP Throttle Body is like NO OTHER! You will find many shops or aftermarket part suppliers will focus on "Capacity/Volume"....that is the wrong approach! We have been able to obtain amazing numbers on what most consider a "small displacement motor" by adhering to our methodology "Velocity over Capacity" (316whp/262wtq, J32a3 NA, 93 Pump fuel, then the same J32a3 boosted on only 8-9psi around 560-580whp & our old J30a5 275whp/232wtq NA on Stock cams & 93 Pump..then 350/340 on the same J30a5 with 100shot of nitrous for 100k miles) . Our setups/engines/parts have been proven time and time again, not only on our own test vehicles/Daily drivers, but also on many of our customers vehicles.
If you're unsure what a "Venturi" is, we suggest looking it up. A "Venturi" is a purposeful reduction in piping/inlet/outlet diameter, this is done to increase the air's velocity, such as a "Velocity Stacks" (Ran on intake's, Ram air, and Turbo's). The reduction for a brief period will drastically increase the air's velocity (again... VELOCITY OVER CAPACITY!). Engine's are essentially an air pump, the more air you can get into the engine, the more fuel you can pump in = MORE POWER!! The reduction in the opening/outlet diameter a "venturi" implements should not be confused with a real "choke point". A Real Choke Point is usually a longer 1-3'ft section/run of smaller diameter piping/tubing that truly causes a "choke" in the motor and slows the air down. A Venturi effect is only for a brief split second/very short distance, then tapers back up immediately to the normal/larger diameter.. This is a quick reduction in size, then immediate taper back to the large opening, and that is what increases the velocity of the air and ultimately allows your motor to pull in the most air possible.
* Great Alternative to the expensive 3.7 IM and 3.7 Throttle Body ($850+).
Knife Edged Throttle Plate Option
Newly added....we are proud to present our "HLP Throttle Plate Knife Edge" option .This is one of those options where "All the small things in the end add up to big power". All of our HLP (HalferLand Performance) engines don't make the awesome power they do by adding huge mods, it's when every small detail is matched and optimized down the line do you see the best results and gains. Our HLP Knife Edged Throttle Plate is yet another step you can take to get to your ultimate power goal. Though the gains will be minimal In the scheme of things, knife edging the plate allows the air to transition smoothly into and through the TB, with the throttle plate literally slicing the air in two and allows it to flow smoothly around the plate, where in stock form it would hit a flat wall/surface (though small) and does effect the overall flow and velocity of the air. As we always say,, all of our PnP work is in place to gain or maintain velocity and with that comes added volume or capacity, as the faster you can get the air in the motor, means the more overall flow you have or can achieve, which is how we can take a stock 68mm TB, open it up to 70mmx68mm and have it gain the same, if not more then a 3.7l TB ???? (With proper tuning of course).
