This was a development intake I designed and built to better understand intake manifold design for a small tire no prep application. I have been forced to change platforms and have learned all I can with this intake. I was originally going to give it away but have since been advised I cannot for various reasons. This intake DOES NOT HAVE A BURST DISC AND HAS FAILED!!!!!!! I flooded the intake with fuel and tried to start the engine resulting in a catastrophic explosion. I welded it back together and still did not add any explosion protection. This is an experimental intake, when you purchase it you accept all liability associated in using it or attempting to replicate it. I built the intake off the factory 93 Lincoln mark viii intake manifold flanges and scrap on the shelf, I do not recall the thickness of the manifold and all of the parts might not even match. I used the factory imrc plates and epoxied the fuel injector holes and actuator holes closed. I used a Tps for a Holley carburetor that I will include and I hooked up the factory map sensor during testing to control the transmission and spark. the map sensor is not included. I ran a mechanical secondary Holley 750cfm carburetor during the smoother dyno pull. red is the baseline and blue is the sheetmetal intake. the weird high rpm spike in power should be negated. I believe that may have been a random torque converter lockup issue. low rpm power was down on the sheetmetal intake from a lean condition caused by a weak Venturi signal to the emulsion circuit. This could potentially be remedied with adjustable air bleeds but the carb is simply too large. I then switched to a 600cfm vacuum seconday carburetor. the low rpm power began to pick up rapidly until the secondaries crashed in creating a terrible lean spot that can be observed in the second dyno graph were the red line is the baseline and the blue line that plummets is the sheetmetal intake with the 600cfm carburetor. This is very condensed version of the testing but the results were extremely promising. I ran the tests on a chassis dyno with a 1993 Lincoln mark viii. If you purchase this intake and attempt to use is add a burst disc and reinforce the intake. DO NOT PUMP THE GAS UNTIL THE ENGINE IS CRANKING AT FULL SPEED. Fuel in the plenum without vacuum will result in an explosion. If you have additional questions or would like additional pictures please ask before purchasing, I will not answer engineering questions or provide measurements outside of whole numbers. All tests were performed at the same atmospheric conditions with the same timing the same fuel the same car and the same dyno and gained 46.81whp at 6,215rpm. I will also include the extra intake gaskets.
