First, kudos to Mike (Orlando_87GN) for being there last night to lend his expertise and support.
After months of trials and tribulations with coolant leaks pass ARP studs and fuel pressure that had (still has) a mind of it own, I finally felt comfortable, make that less nervous
, enough to test the car. Only change to the setup was a Max Effort 16-pos for Blues.
The PTE-51 spooled up nicely in street trim but was an absolute dog in race trim. I could barely get 2# boost on the t-brake and those that know the car commented how sluggish it was off the line. Encouraging thing is that it got a 1.76!. Started out with very low boost, 17# and the car running extremely fat. There were a lot of strangeness in the cockpit and I was so tense I never glanced again at the boost gauge after seeing 17# in the early run. I am sure no one else has had that problem
.
I upped the boost 2 turns on the rod and saw only a 2mph difference. Upped it 2 more turns and the car went from 12.26 @ 113.33 to 11.73 @ 118.6. Finally came to life but I have no clue how much boost and the laptop lost power before I could save that buffer. Fuel pressure was supposed to 48#, but it had dropped to 46#, so I reset it to 48# and made one more pass. This time I had 0, nada, zippo boost at the line and ended up with a 1.89, 11.90 @ 118.53. Checked the fuel pressure after the run and....surprise, 50#. DS showed the O2s up in the 840-855 range.
Disappointing but not unexpected night with encouraging signs. Despite the car being a dog off the line, it was only .13 off its best 60'. Despite the O2s getting up to 855 and running what I would guess is about 20-21# boost, the car was only .2 & 1.91mph off its best (only ran it once) with the PTE-51. Despite the MPH being 1.91 slower than the previous best, last night it gained 2mph more in the 2nd half.
Hopefully I can get the fuel pressure problem solved soon and improve the spoolup. The Max Effort showed such a dramatic spoolup improvement in street trim, maybe there is something that can be done to improve spooling in race trim.
You listening Steve?
