WTM V2 hits the dyno, again!
Well since I was at the shop last night and couldn't work on the T/A we decided to starp the Ol Formula to the dyno and see what my simple mods made power wise. Last set of #'s was 134 RWH and 231 RWTQ and it ran a 17.38@80 at the track since then I added a K&N filter and lid, a new standard muffler, changed the plugs to NGK's, wires, cap, rotor, and coil to MSD stuff and replaced the distributor and module with a stock unit. I also changed the tranny fluid and filter. The dyno was just re-calibrated, WTM was the first car on it. Had to do all my pulls in 2nd gear because I can't wind out 3rd because of the governor. Also it was 22 degrees warmer then the last test. Anyway when all was said and done I ended up with these #'s
138RWH
227RWTQ
also there was a BIG gain in midrange, roughly 10HP acrossed the board, although peak remained roughly the same. So anyway we brought up the 1/4 mile program and the first pass I made in Drive and it ran a 15.6 @ 84 MPH. Next pass I shifted and it dropped all the way to 15.2 @ 87 MPH. After a cool down period of about 30 minutes I made another pass and got a 14.98 @ 89! Probably a bit optimistic but the T/A was fairly close with a 12.18 when I 1/4 it on the dyno so you never know. 3 more runs were all between 15.0 and 15.2. Hopefully I can get out to the track for a couple passes to try and back it up with some real #'s. I'd expect somewhere in the 15.2-15.5 range. Either way much better then a piddly 17.38. So with some fix em up stuff and a lid/filter and by shifting on my own (most important here, stock program shifts at 4000 RPM) I dropped roughly 2.4 seconds in the 1/4 mile and gained 9 MPH. Next up is the track test and then we are going to install a Throttlebody spacer and a fuel injector spacer and do it again.
