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.... |

Brett, I had you in mind as well when I did the testing..
I'm gonna play with a bunch more combosand I just found my 4" stacks a few minutes ago while looking for my spray gun to paint the interior of the new shop! Damn place looks like the OR at the local hospital! Its so bright inside that I'll need shades to assemble things! The decks are super glossy epoxy and the walls are 3 coats of the same paint used on the underside of Delta aircraft.... every bench is stainless steel.. Its bitchin! BTW, I guess no one noticed those NOS foggers in the manifolds..... You should see what it did when I sprayed the juice to it! |
