Well, the Shootout has come and past! Although I couldn't find the required time this year to dedicate to the car and had more freeze plug trouble, I did get a single dyno pull and a single pass at the track before throwing in the towel.
Dyno Pull:
I waited till literally the last minute to put the car on the dyno. Thanks to Kurt K. and whoever passed along the word that I was interested! Only minutes before that were the only real full throttle-to-the-redline (or so I thought) pulls that I made on the street with the car running very well...the engine ran amazing, so I pulled back into the hotel parking lot, right in front of the dyno. Less than 10minutes later, it was getting backed up on the dyno
It ran pretty rich on the datalogs (11.3-10.9 beyond 3k rpm), ACT's were low (less that 100F), and timing was conservative (22° advanced), so I didn't feel bad about giving it a spin on the dyno. So, here are the stats:
Mid 80's in the sunlight
Engine pretty warm from "street pulls" - 180F-190F coolant temp
Timing @ 22° max advance
Rev limiter at 7500rpm
25% OD on MPx w/abradive rotors and engine detailed in this thread...had put 200-300miles on for break-in, new 15w-50 Mobil One
Alky System on, ~5gal 93 Octane + 5 gallons 110 Race Fuel (Leaded)
Got BE logging the run, dyno operator did the pull in 4th gear and told him to aim for the max range of the gauge (about 6500rpm I figured)....engine ran well up to what sounded like the rev limiter (stock gauge was maxed out....even "stuck" on the bezel after the pull....lol)....right as the dyno operator was letting up, another freeze plug shot out and dumped the 50/50 coolant everywhere.
It seemed like it hit the rev limiter kinda fast was the only other notable thing I remember. AFR was still really rich of course.
Seemed to me like an overall crummy pull, with the low timing and seemingly low rev limit,
but still managed 387rwhp and 437rwtq (peak HP was at about 5400rpm).
Well obviously, they were done with my car after the freeze plug, so thanks to help from several of the guys, we got the car pushed back out of the way.
Looking at the dyno sheet and dyno pull log, I learned several things....
1) Power dropped off at 5500rpm (should have kept going with this motor)
2) Boost DID NOT drop off - started at 16.5psi and only fluctuated a little all the way up - so no significant belt slip.
3) car was still running rich, 11.2-10.9 or so.
4) spark advance maxed out at 22deg @ about 4500rpm - I'm thinking with the new operating range of RPM's, I need to ramp it up to it's max at a higher RPM. I had planned on going up to 28deg on the second pull.
5) AND lastly and most importantly.....I pegged my slot MAF sensor in a 4" tube at around 5500rpm!!
....That was the limiting factor! So I'll be grabbing an SCT BA5000 now.
Anyway, call me optimistic, but I feel like I could have EASILY surpassed 400rwhp, but do to my lack of preparation, I did not. Perhaps the car would not have even made it to the Shootout if I had beat on it to the point of more freeze plugs popping at home though....
