Took off early from work (actually snuck out ) to check out the A/F ratio on the Predator tune since the pulley install.
454rwhp/476rwtq SAE
The top end actually hit 10.0 at one point. It was in the high 10's low 11's in the entire top end (10.0 @ 5000 to 11.4@6400). Needless to say, I'll be getting James at RWTD to tweak the tune. The mid range needs to drop a hair (typical Predator pulley tune) as well.
460+rwhp should be doable, especially with a cool engine (all runs were made with the engine starting at 80 degrees C on the trip odometer readout.
It's nice to punch it at 50mph and get sideways.
Mods:
K&N bigmouth
MAC O/R h
MAC 2 1/2" catback
2.77 pulley
Predator pulley tune
Question: Once the gas is let off at the end of the run, I got a nice puff of blue smoke. Has anyone else noticed this after getting outta boost? Is it sucking past the PCV? It wasn't a lingering smoke, just a good thick puff and then it was gone. Just wondering.
