I was going to ask if you had a plot that showed Throttle position. If that was all WOT I am honestly not impressed. I know it was not fully tuned and you had a catastrophic failure but a plot showing a powerband that only comes in full force at 5k rpm is blah. I will be in to see results for the next attempt with a full tune though.

As far as the spool up - this is with no VVT tuning so I could give less flucks about what the ramp looks like. Please show me a car making similar power that holds that steady of a torque curve. Please.
This is also a 3076 turbo not a 2860. I posted this because you were asking about my torque curve. It does not fall off like 99% of these cars that are on the rollers.
Again – this is not a final plot, it may not have even been a full WOT pull. Just an example of my TQ not falling off.

If you are referring to the "knee" in the 5000rpm range, that is probably where the boost controller stopped allowing the manifold pressure to increase any further, but allowed it to maintain that pressure from there on up the rpm range.

A note on Valve springs.....I had a set of 94 springs tested to compare to a set of 99 springs and at the height where the 99 springs produced 50lbs the 94 (95 is also suppose to be higher) produced 65lbs. I am sure Bryan will rebuild this to a once again badass machine built for what he likes. Personally, I want a more "civil" "street" car. My car will please me, his will please him.
Thanks for putting it out there Bryan!

I’m sticking with the stock cams. The spring package I picked up at a bauce price, I went with the Dual 74lbs springs. Should allow me to rev it out to about 8k and take advantage of that power up top.
Snagged this set (the 74lb set):
