LOOKIN GOOD

 

Seriously how are u doing this safely on straight 91 octane? At the same Dyno as you Shawn church dynoed my stock f20 to 450whp on 91 octane and 507whp with my build 2.4l on 91 octane. On e85 it makes way more power but how the hell are u making 550+ with a supercharger and only on straight 91 octane? Are you running water/meth injection?

 

Another reason why he might be able to run 91oct is because he isn't seeing full boost until redline since it is a centrifugal supercharger.

 

Nice numbers!

 

Looking good like usual! Keep it up!

 

Nice! I bet if you lower your VTEC to around 3600 rpm, you may be able to get that dip out. Have you played around with moving the VTEC either way to see how it does to correct the dip?

 

The fuel was one year old Union 76 91 octane and after the first 10 minutes on the dyno it was pinging. We couldn't get past 4000 rpm with out the ping. I added one gallon of race gas to the full tank of 91. It was the equivalent of 92 or maybe 93 octane. No methanol.

 

Impressive numbers!

 

Alright, gotta be completely honest. I've looked at that dyno graph maybe 15 times since it was posted, first out of curiosity, then mainly astonishment at the numbers (especially given that the highest rpm and the most power is not represented. besides one year old pump gas.) This morning I look again and notice the torque climbs right along with the hp without flat-lining or dropping off somewhere in the middle.

How?

 

Less cam overlap with plenty of boost is my guess. It does require rubber shorts when the tires start spinning at 90 mph.
