Yep,
Remember the posts about URY and his "too tall" stacks?? I decided to post the data from my latest engine combo as i try to find the perfect stack arrangement for it.. Guys wanting a cheaper, reliable TIV engine will love this one because it has a ton of torque and awesome smoothness. It does NOT have ported heads, so its almost 1,000.00 cheaper than some of its bigger brothers and makes torque very similar, but does not have the RPM range.. Ultimate daily drivin, short shiftin, 901 abusin power- plant.. Anyway, look at these plots and descriptions for this engine here http://www.shoptalkforums.com/viewtopic.php?t=80579 I plan on replicating this exact test on the next 10 engines I dyno and see how port work and cam changes effect the results. The results from this engine do not follow suite with my earlier findings, but almost all those tests were done on high revvin engines.... |
