AWeb80 Posted January 11, 2006 Report Share Posted January 11, 2006 Chris, I thought the 3.4 only weighs like 50-75 lbs. more than a 3100...? Quote Link to comment Share on other sites More sharing options...
chadz34 Posted January 11, 2006 Report Share Posted January 11, 2006 my ass dyno showed that my LQ1s still had more bottom end then the 3100 in my cutty did My ass dyno is very unaccurate. I rated my Z34's horspower at 319.4 @ 6126 rpm and 323 ft lbs. torque @ 4670 rpm. P.S, my only mod is me being the driver. 8) Quote Link to comment Share on other sites More sharing options...
gp90se Posted January 11, 2006 Report Share Posted January 11, 2006 The 3.4 has gotta outweight all the 2.8s-3400 motors, cam carriers, 4v cylinder heads, the bolder with holes they call a plenum and I think the exhaust manifolds weight more on a 3.4 then a 3.1 for whatever reason.

TeeJay3800 Posted January 14, 2006 Report Share Posted January 14, 2006 Too bad we dont have any dyno graphs of a stock 3.1 to compare to a stock 3.4. You would see that the 3.4 has more low end power than the 3.1 does. I have a factory 3.1 crank dyno chart. It's in a 1990 Olds Cutlass series catalog. It shows the 3.1 producing 175 lb-ft of torque at only 2400 rpm. I doubt the 3.4 is producing that much at only 2400, but we won't know unless someone produces a 3.4 factory graph.

birdman Posted January 14, 2006 Author Report Share Posted January 14, 2006 i would have to agree, it really dosnt seem like it does good below 3k, but then again we've proved that my car sucks so what do i know. Quote Link to comment Share on other sites More sharing options...
joey b Posted January 14, 2006 Report Share Posted January 14, 2006 and that chart is for the MPFI 3.1, not the 3100. Quote Link to comment Share on other sites More sharing options...

I will, but its pretty small, so hopefully it will still be readable. There's also a lot of other stuff on the same page, so I'll have to edit all that out before I enlarge the dyno chart.
