Buschur 2.3L RPM + BBK-B BB + E85
I have the results.
27psi it made 456whp/391wtq
24psi it made 427whp/362wtq
3400-6500 in 4th gear...torque is pretty much above 350wtq. Then drops to 317wtq by 7000rpms.

This is on E85. Just to confirm.
Awesome result. We who use FFTec know and appreciate safe-tunes rather than Hail Mary types.
By pushing hard GST-Bryan Medway, has reached over 500whp on same (calibration) heartbreak dyno, which gives you headroom should you/FFTec ever care to explore the upper limits.
The flat torque on conservative Track Tune will be a benefit.
Hope you can post dyno, would love to see it.

This is on E85. I don't have the boost plot at the moment. When i get my accessport2.0, I will do a pull. Right now, it is lost somewhere.
Dyno sheet will be up soon.

All i know i am making maximum torque at 3300rpms for 24psi in 4th gear. 3400rpms for 27psi in 4th gear. So for third gear, I am guessing add another 400-500rpms. So 3700-3800rpms in 3rd for 24psi. And 3800-3900rpms in 3rd for 27psi. On track you never see below 4500rpms unless you see a really slow slow turn (sub 40mph). Then you would be in 2nd anyway and at a higher rpm.

In your first post, you predicted 460 whp and 410 ft-lbs at 21 psi. Always interesting to compare expectation with reality. Seems like the new motor is producing about the same peak numbers as the prior setup? Maybe the 460/410 prediction was for a different dyno?
Nah, I overestimated what a high compression motor would do. lol. I was referring to same dyno. haha I was off. If it was tuned for 30-32psi...kill mode, it would be a fricken beast!
I think this is a real-world example of properly tuned track-car, that will sustain couple of years of track-abuse.
Regardless what Zhong predicted, the BBK-B is the gating item to performance on this Buschur 2.3RPM engine: if he was willing to give up low-end torque he could make lots more.
I like to see conservatively produced data on conservative dyno.
460whp before even breaking-in the engine (I am sure it will make more once its broken in few thousand miles down the road) is great power with broad torque curve.
Zhong is out to win, and to win you have to finish. Conservative tune will finish.
In addition its my understanding this is his only car, so his Daily Driver and winning time-trial car.
Making 2x of the power what Evo X makes on this same dyno in stock form.
Up for Dyno: we are all waiting, patiently.
