First and foremost Extrudabody is NOT like any other Company! We innovate and do not follow convential rules.
Trumpets and Plenums: Trumpets protruding into a Plenum is not the way to make power...... air entering one end, center or the other WILL TAKE the path of least resistance filling 1 cylinder over another unless the plenum is huge, sonic waves back into the plenum further disrupts this flow reaking havoc for cylinder to cylinder balance! The slight increase you get from a colder air charge is NOT offset by the Plenum embalance from cylinder to cylinder. If you want cold air induction Isolate/segment the engine bay and feed cold air to it!
Now factor in the fact that most ECU's are batch fired injectors, which means all are spraying the same amount of fuel, with each runner flowing different amounts of air this means some are rich and some are lean! Ok for the rich ones, not so good for the lean ones! The ECU's that are Sequential or have Cylinder to cylinder Fuel Trim still requires a Thermocouple or O2 sensor in each exhaust tube to tune the trims.... and this starts driving costs way up
Trumpets: What you don't see you still get! Do Trumpets make power or does the Radiused edge that rolls the Airflow into the Body make power? Most all ITB/Weber trumpets have a small 1/4" to 5/16" bead or rolled edge. we used 1/2" with the 45mm and 48mm Taper bore ITB's. The Velocity stack is built into the ITB Body!

Here's a bone stock VK5.6ltr V8 from Nissan that made 401hp @ the Wheels with 45mm Taper Bores, Jim Wolf Cams and Headers! This was a MAF Sensor based Buggy build. Wolf wanted to run stock electronics, hence the size of that Plenum, you still do not see Trumpets protruding into a plenum, as it's hard enough to get high velocity air to turn, imagine trying toget it to make a 180 degree turn around the LIP of a Trumpet!

Extrudabody Electronics is not Based on MS, but an OEM Based ECU from Europe with over 20k running examples!
Here's a tickler: M50 Sculpted 3D CNC Billet manifold! The Plastic SLA piece below costs$1000 and all it does is check fitment! As you can see R&D Costs are quickly eating profits to the point most companies do not make a DIME on the first 15 to 20 systems they sale! This is just part of the business!

By the BMW! That Filter Housing is Nice and Conveinent for changing oil, but it's a PITA when trying to get ITB's to fit under a Hood! :)

Guys we will help anyone get to where they want to go, but in the end we have to make money to stay in business. With 100% USA Manufacturing we are not the cheapest in town, but if you want Quality on your car Extrudabody can offer that at a reasonable cost, with innovations no one else can match.
And forgive me in advance, but we simply do not have time to tune into the forums on a daily basis! I've also divulged lots of information hope it's seen as what it is an explination of what a developer goes thru to bring a product to market and not a SALES Grab!
Check with Levent of the M10/M20 stuff!
Thanks
