Euro 1,6 99-00 @11PSI - shouldn't this be more?
Hi folks,
I went to the dyno lately with my setup:
Euro 1,6 NB (99-00)
GT2560R
2,5" exhaust, metal catalytic converter 200cell
MS2 (DIYPNP) running sequential injection
EBC through MS2 - with the new 3.0.3u code @ ~10-11PSI (170kPa with 98kPa atmospheric pressure)
Weather was total crap for dynoing... ~38°C = 100°F
This is the dynosheet I got - the values are uncorrected.
The sheet shows 133.5 wheel-kW which equals ~179 wheel-hp.
uncorrected.
The DIN correction here is:
correction factor = (1.013 mbar / atmospheric pressure [mbar]) * ((273 + temperature [° C]) / 293)
Which in my case goes like:
correction factor = (1.013 mbar / 980 mbar) * (273 + 38°C / 293) = 1.097
So the corrected value should be 179 * 1.097= 196.39 wheel-hp
(Would you confirm this?)
This is what my datalog of the run looks like:
I dont like the spool-up I see - the old T25 gave me 10 PSI @* 3000 RPM - what could cause this?
Other than that I would like to here some comments.

10psi, low-reading dyno?, 100*F, 200whp sounds pretty close. Add in a 2.5" catted exhaust and it's very believable. I made 217whp on a Mustang dyno with a '99 longblock, but that was with a 3" exhaust and more boost.

I would have guessed based on your description at about 180 whp, so seems pretty strong to me.
Euro 1.6 motors tend to have very weak cam profiles. Keep in mind that the 99's over here have 239 more cc's of displacement and more aggressive cams. Sure, my car makes about 10% more power at the same boost, but it's not a fair comparison. However your power is right where we normally see a 1.6 with a GT2560r running the same boost.
