Here it is guys!
Its not pretty sitting there all naked and bare without it's Gelcoat on, BUT at this point it just has to function and be proven. It still didn't turn out too bad considering it wasn't made in a mold! http://www.aircooledtechnology.com/r_d_914_dtm.htm Nevermind those pics of engine parts- Charles goofed up when he loaded them in a jiffy for me today. (those are a newly designed piston for a wild chamber Len and I designed and a 66x100 bore size) We finished the mock up over the weekend and its ready for the dyno next week! This shroud is the first one and it is set up for guys with full external oil systems, full flow and accusumps- like my car. After I make this version work it will shed some light on what I need to modify to physically go further with to fit into the 914 and still utilize the factory oil cooler. I have two possibilities of that at the present. The other design locates a small efficient cooler normally used externally in the sheetmetal just forward of the engine toward the cockpit of the 914. This version will blow air into a duct we are making now, through the sheetmetal and out the bottom where another duct will be that has a venturi effect to help pull air through the cooler even faster as speed increases! Its amazing that I have gotten this far with it with everything else going on here!!!!!!!! For those that are not on my list but would like to be email the Mad Scientist at productdevelopment@aircooledtechnology.com |

All that velocity stack info is highly proprietary! I posted some tests a few weeks back but after my last round of tests and the results I won't be doing that anymore!
The power gains with certain stacks with certain manifolds on certain combos with certain exhaust systems is AMAZING! When I see people running huge stacks on a TIV now it just makes me laugh! To answer that question directly... "The short stacks and short manifolds compliment the engine combination when coupled with the Tangerine Racing Header" BUT I'll be testing the hell out of this combo with various stacks and manifolds for sure because this is MY engine for MY 914! I'm not afraid to wear it out on the dyno... As for a Horizontal fan system- It is worthless- This set up has beat the shit out of everything I have tested and ran in every application- Period. MORE AIR DOESN"T MEAN SHIT! You must direct that air to the pertinent parts of the engine that run hottest, the DTM does that with no sweat. Notice that Velocity stack on the rear of the shroud?? Tht is the artwork of spunone- a member here. I had him make it to try and muffle the whirr of the cooling fan which can be pretty loud in a beetle, yet alone a 914 where the engine is right behind your head. I am going to test it with and without the stack to see if it impacts cooling and sound. As for cost, this version will be about 785.00 +/- for the shroud and air sealing tin to seal it up like factory.. Yes, the DTM does away with ALL factory tin and you can drill it for 1.7/8 or 2.0 spark plugs! |
