Procharger Dyno Just back from tuning the engine after the Walbro 340 and 42's injectors install.
Last time:
451.1 RWHP 514.8 RWTQ
This time:
474.8 RWHP 538.6 RWTQ - Unlocked
486.4 RWHP 440.4 RWTQ - Locked
But the biggest improvment was at part-throttle.
It was so pig-rich between 2500 and 6000, AFR was below the scale @ 10:1
AT 5200 rpms, RWHP was 325, RWTQ was 325. After getting the AFR leaned out to 11.8, RWHP jumped to 400, RWTQ to 400
I can feel that 75 jump.

I will be going to the 1/8 track on the 25th. I doubt I can beat my N20 times.
I am currently running 5-6#'s of boost with 11:1 heads.
When my FI heads get here, more boost.
On the last run, I ran a 35 shot. TQ when up to 595 but HP only jumped to 475.6. Is this normal??

Verdad Gallardo OT: but how is your tune with the 11:1 compression; both n/a and FI. whats your timing at and do you have any problems with 91 octane. my compression for the new setup will be 11.1-11.5 and im worried about detenation.

I have it tuned conservatively because of the high CR. Timing is set @ 19. Target AFR was 11.8 - 12.0
This was all running on shitty 91 octane
I may set it back to 17-18 on the street to be safer.

DAMN! Nice numbers, and you are pulling to 7200+ RPM, holy **** batman!! That's awesome, and it never dies off for the HP, that car must haul! That torque is incredible at 2500 rpm, tires probably don't like it much

Thanks! It run great! Half-throttle just puts you in the seat.
The torque converter skews the rpm numbers. I was running it to about 6500-6800
Heres a 35 shot. I forgot to set my Window Switch higher, so it cut the N20 @ 6300 grr...
