It looks very bad. That thing doesn't look like it would flow smooth or even. Stick with the stock one.

im interested in the thought process of the designer for the fuel delivery location for both the primary and secondary injectors...

The runners are both different O.D/I.D as well... most intriguing. quite.

I 'm trying to find the thread where the guy made a custom intake manifold, was super excited, and found out he lost like 20whp when he dynoed it.

Only useful for aggressive high overlap ports in a turbocharged application.

Short runners, lack of staged throttle. Not something you bolt onto a nearly stock 6 port and have fun with.

One would have to perform some calculations on runner length and volume to determine the powerband with various port options.

Obviously a standalone is required.

well i dont plan on using it right now as the engine is stock was thinking more when i port it and all that fun stuff the photos dont do it that much justice it looks better close up .. and yeah the different size runners had me wandering as well maybe more air for the secondary ports and i dont know where im going to put the injectors like what 2 runners get the secondary s and what 2 get the primary's .. i have time to think everything over wander what others will have to say on it
