Dyno Numbers
hello,
recently i took my GN to a local dyno to get some base line runs. I made two runs on 93 octane ,which i think was a big mistake.I should of been on the safe side and run race gas. Well anyways i thought for sure the engine could easily run up to 6500 rpms.Power peaked at 5700 rpms than it Maybe missed or pinged causing dips in the hp curve(see above pics).Fuel pressure never dropped and peaked at 60 psi with boost.
1.So my question is what could cause this dip ,detonation, could it be tune, octane,plugs?????
2. Could the turbo cause this car to peak alot earlier than i expected (5700rpms instead of 6500)???surely there is more power to be gained at higher rpms, or no??
3. If i raise boost will it peak even earlier???
4. Dyno operator said AF was alot higher than he would feel safe with at 93 octane, whats your take??
Orginally i thought the turbos were 60-1 ,i was told the turbos look alot bigger than 60-1.here`s a pic of the engine bay
