Cartek's Research and Development program is what keeps us producing cutting edge performance that is second to none. This is shown through our constant progression toward newer, better, more efficient combinations that keep us, and you, ahead of the competition. Research and development is our biggest asset; our in house machine shop and porting area in combination with our fully automated flow bench allow us to continue to squeeze more and more out of the many custom tailored combinations that we produce. For example flow bench testing on cylinder heads is more than meets the eye here at Cartek, using velocity probes to empirically ascertain the real gains in a port by mapping it out as opposed to using the old school "we'll hog it out to make it flow better" approach. Bigger numbers don't always mean better, just look at our track results. Our on track performance speaks for itself; the proof is in the pudding.
