Eps big bore TB's

as far as why we didn't use a 75mm throttle body for the base kit. simple... we tested it, religiously. if tapering down to a stock bore behind it, (and lets be honest, thats most of you), there is no appreciable advantage to the 75 over the 70, especially considering the loss in throttle resolution, and added difficulty in attaining idle stability (particularly on HR cars that dont have the ability to shrink the cams and limit airflow at idle)... combined with an even more difficult packaging nightmare. while i can assure you all that there is a 75mm throttle body based product coming from eps, it will more than likely not be designed with the intention of bolting it to a stock plastic manifold, even if it CAN. hogging out the inlets of the plastic manifold to 4" and putting twin chevy 102mm tbs on it isnt the future of na vhr performance. YOUVE GOTTA CHANGE THE SHAPE/FLOW CAPACITY OF THE RUNNERS! our focus is on bringing you guys the right products that actually work, and have been documented to work, not stuff that sounds cool but doesnt do anything.
