Some say go six, some say stay four or go BIG four.
At what point does the SIX take over? I run a 90 hp four and have been told that my 'lil SIX will make me slower with my 130+ hp. PO says 245hp. Won't truly know 'til dyno day. Which may sway me. What kind of weight increase are we talking about? Will I enjoy the car more on the street with the SIX? Because let's face it I run 1-2 a/x a month compared to my 200 miles street driving. a/x season is coming to an end soon. I'll finish with the four. My project will be during winter. If the SIX is bogus I'll put the four back in. (IMG:style_emoticons/default/confused24.gif) Only my time with my car hobby has been spent.

QUOTE(trekkor @ Aug 15 2004, 09:43 PM) At what point does the SIX take over? at the point on the dyno curve when the six starts producing more power... stroke and compression being equal (which they mostly are on the 1,7/1,8) a big piston will produce more torque than a little piston. a 2,0 4 will produce more low torque than a 2,0 6. the 6 is starting to get into the meat of its power curve about where a D-Jet cam is falling off the top. on the road - plus or minus a little - the crossover point is around 70-ish -- this is why 4's tend to be quicker at AX - where the speeds rarely exceed 70 and the 6 carries more weight. no matter what you do - there will always be SOME engine that makes more power and goes faster than yours. enjoy what you've got and learn to drive it - this includes keeping it in a rev range that's appropriate for the task at hand. |
