Engine question.

Do the holes on the bottom of the engine have to be lined up? I've seen different answers on this. I didn't see it in the stickies. If so, does lining them up help with anything in particular? I know this has come up somewhere but I didn't see it.

I currently have my SC Engine tightened down & it seems to be cycling fine. But I've only put a few bags through it. I may have to wait until June or so before I can test it either way as I have to pay for my new board & grips before I spend money on paint.

If you do not have the holes in the correct place then they will not line up with the channels in the body that supply the engine with the needed air.

The holes won't prefectly align, but they all need to be facing down-ward(pointing to the frame)

What specifically does it help with performance-wise? I have shot it, a tech shot it after installing my new board & a few of my fellow refs shot it.

I will say that it appeared to not be cycling super fast with a Z2 or my hopper. Around 17 bps peak according to my Yakuza. PSP & full auto uncapped. Would the increase in flow be enough to help my efficiency? LPR is at 80 psi, HPR around 190 psi (I believe) & dwell at 6 ms. Shooting in the 290s.

Those holes are important because they are air passage holes. If they're blocked, or not properly orientated, your LP air will not travel properly and can cause low FPS

Will it shoot much higher than it is now? It's already in the 290s.

Sounds like they're lined up properly, then.

You'll be able to lower your pressures some, but you are probably aligned correctly.

I just lubed up the engine as I am potentially playing this week. The air passage holes are not lined up. There should be three correct? I know there was a picture somewhere from years ago.

Mike said something about slightly loosening up the engine helping with something in his Marq 6 maintenance video. I think it was for kick or consistency. I don't seem to be having this issue. I can check it again on Thursday.

Do the SC Engine poppets need frequent lube? I haven't even looked at the poppet itself since installing the kit.

I may be playing tomorrow. So quick help is appreciated.

Every time I cleaned my SC engine in the Victory I would make sure the poppet had a little Dow 55 on the o-ring. But I would think you are fine if it is not leaking.

I believe there were two air passage holes facing down. They were not perfectly aligned with one another. This engine shot super nice on PSP 12+ in the 270s. So I assume it's fine as it is. Unfortunately I put less than two bags through it.

The summer is young & I am looking forward to putting more & more paint through this beast.
