Electronic ITBs for your classic air cooled Porsche engine! Computer CAD designed and optimized, custom CNC 6061-t6 aluminum adapters with electronic throttles. Includes ID1050x injector set, electrical connectors for throttles. Hand made and tested water to air heat exchangers with 12an hose fittings. High flowing 2.5" welded inlet plenums with 2.5" y-pipe connector. Made with super high quality BELL intercooler cores. Cores are all leak tested after assembly!
These come assembled and ready to bolt on your engine! Available in 2 bolt intake style or 964/993 engine 3 bolt intake.
Inner and outer intake runners are CAD modeled to be 99.995% equal in chamber volume.
These are made to order, please allow at least 30 days after ordering for production.
Lower manifolds are now BLACK anodized. Additional coatings for the intercoolers and plenums available - Just ask!
Lower intercooler plenums now available CNC aluminum for extra cost.
New upper boxes and inlet adapters are 2.5" and allow more clearance. No loss in flow! 2.5 inlet adapter available in CNC aluminum for extra cost.
The prototype setup made 300whp and 300ftlbs (around 350 at the flywheel) on a stock internal 1975 2.7 engine at ONLY 0.7 bar (10 psi) boost! Intake air temps stay just over ambient even with hard driving or repeated dyno pulls. No air to air intercooler will come close to being this effective! This setup should easily flow whatever boost you throw at it. Inspired by Porsche 934 / 935 style turbo water to air intercoolers that have been proven at over 750whp.
Complete setup weighs at just 12.5lbs per side!
Recommend CWA50 or better pump. Heat exchanger in front and 1 gallon water tank.
Comes completely assembled as pictured.
Also includes:
Full set of stainless steel installation hardware with jet nuts for lowers
New Injector Dynamics ID1050x fuel injectors fitted to throttles and fuel rails
Wiring instruction for throttle motors
Fuel quick connect adapter info
Basic settings for EFI settings
Electronic ITB advantages:
* Large 47mm throttles (ALSO available 49mm) can be tuned to any engine size
* No linkages to adjust, maintain or install. Cleaner, less crowded engine bay
* Works with any modern programmable EFI (Recommend Motec)
* Far better driveability over cable ITB or throttle
* No idle motor required
* Easily add cruise control
* "Soft" Rev limiting
* Torque reduction traction control
* Rev match, launch control, flat shift, and sequential gear box integration
There are no disadvantages over a cable / mechanical setup. Get some modern tech with vintage flare and sound on your air cooled Porsche!
These should fit any air cooled Porsche engine. Please ask if you have any questions. May not fit with some AC compressor without some changes (seems to fit early, measurements available on request)
Will require turbo style engine lid. Please check measurements with me to make sure it will fit your lid! The total stack height can be shortened if desired by 2-3 inches

CALIBRATION FOR MOTEC M1 SERIES ECU:
MoTec M1 Throttle calibration procedure (without disassembly):
* Key on
* have throttle pedal already installed and calibrated
Open initial setup 2 and open throttle settings tab
Change power save delay to 10000 sec or some long time
enable throttle test static test (throttle test window at bottom of throttle tab)
Press throttle pedal to exit power save mode
Drive throttle position with test to 0% (you may need to go to a different value first then back to 0%)
Quick calibrate (q key) Throttle position sensor main offset
Drive throttle position with test to 100%
Quick calibrate Throttle position sensor main scale
Drive throttle back and forth to 0-100% to check operation.
Now we need to force the throttle motors to go as far as possible! This is critical for idle etc.
Take the LOW (main offset) value and go LOWER to try and move the throttle further closed. So if it's 0.5V, try 0.475
After you make the change, you'll have to reset the ECU, and then touch the throttle pedal again to get out of power save mode.
Drive the throttle to 0% again. See if it reaches the specified LOW value. You can watch the value at throttle position main voltage.
Continue this procedure until you get the value for the throttle totally closed. Enter this value as main offset. Drive throttle again to 0% and it should read 0% position and your value. Press Q key on main offset to auto calibrate the value and apply it to the tracking values.
Now, do the same procedure with the full throttle setting (main scale) this time driving to 100% until you get the highest number possible. Again, after you get that, quick calibrate to apply to tracking values.
Repeat for the next bank of throttles.
After you're done, power up and check that throttle aim and position tracks pedal input for both throttles.
This should be done BEFORE any throttle balancing or idle tuning etc. Left and right banks should have pretty even lambda reading when running.
*****
Alternatively, you can do this procedure easily manually if you have the filter / inlet assembly off.
Manually move the throttle completely closed with your hands, quick calibrate main offset, manually hold completely open, calibrate main scale.
