about 275, which seems 100 down from even the lower end. the stock exhaust wouldnt restrict it that much.
just did a comp check, 240 psi across all cylinders
id1000s, sos rewired walbro 255lp, 93 pump
80% humidity, 100F ambient, 115F IATs (sensor in manifold not charge pipe)
using NGK Iridium BKR8EIX
compression #4
compression #3
compression #2
compression #1

Bought a used kit and in the middle of an install here. Stumped on the injector install as it seems all my parts are not here and the instructions are vague. Do the new 1000c gram injectors require fuel basket in the rail? For the assembly of the injector going into the manifold I have it adaptor ring (plastic), stock injector cushion then o-ring on the tip of the injector. Does this sounds right? Installed the injectors into the rail and manifold and seems nice and snug but I'm just not sure as I'm missing the other 4 pieces from the injector kit. Are the four pieces I'm missing just replacement for the stock injector cushion??

anyone with a c38 willing to measure their inlet outlets to confirm numbers?
i'm seeing 76.xxx mm on the inlet OD and 63.xxx mm on the outlet OD
that makes it a c38 right?

Just installed my V2 kraftwerks kit on my AP1 with AEM EMS, 1000c grams injectors and kit fuel pump. Bought the kit used from a local who claimed he pushed 420whp with an Evans tune. Just got mine tuned Friday with same bolt ons and same everything and only pushed 358whp at ~14.5 15psi , 93 octane on a "dynomite" hub style dyno. Do you guys think it could be the dyno reading so low? What the craps going on? Car drives and performs great just not the number I expected. I guess this tuner also did a kraftwerks Miata that had similar results not pushing expected listed hp.
