Those are some great numbers Demon. What your torque at from 2000-2500??
The 3L (Yamaha) can not mount to the MTX-75, neither can the 3.2L (Yamaha)
The 3L "Duratec" can.
About the Tourque...
Not only do I never drive below 2500rpm, I definitely didn't dyno that low... This is afterall a DOHC engine.
Dyno graphs starts around 2600rpm with a pretty flatline 168 until IMRC (3300-3500 range) Then of course it drops noticeable (down to 150ish) Climbs to 160 by 4800rpm and stays above 160 until about 6000rpm) Then slowly drops off until stock 7000rpm redline. Not too shabby at all for a small DOHC engine IMO... Have to love the SVT cam profiles.
HP hits 150 at 4900rpm, 160 at 5200rpm, 170 at 5550rpm, 180 at 5950, 185 at 6500 and flutters until redline (all above 185 - either too much advance or too little fuel or too small upper intake???)
With a higher redline the HP will just remain flat until about 8k according to the computer models. Not that you would take it that high (safely anyway)
