He said I mentioned a larger fuel line. I also recomended he move the pressure sensor to the pump outlet to test the theory it's too small of a fuel line.
But I'd probably risk over taxing the pump a bit over popping a engine. Or even set up a return system at 65psi. With the stock bypass on a Hobbs switch.
Hummm, the best of both worlds maybe? I do have the stuff for a return system with 3\8 hose at the house. But I never installed it from concerns about it.

BTW, I've never changed my distributor cap. It's probably about due but I can't find it

Just discussing it. It's a topic that concerns me a lot. I haven't had the time to head into your range yet. I'm just working on going from 8 to 12 psi at the moment. I know I have enough injector and pump, but I don't know about the stuff between. I'm trying to steal a little from yall and maybe add to it too. When I get to a point of experiencing pressure drop I'll test it myself.
It was a random thought I had as I was typing. Over drawing the pump would be a concern, but if your only doing it while in Boost than I don't think it would be a concern.
On another quick thought. If your at 40psig-16psi boost. That's only 24 psi differential across the injectors. Your losing a lot of flow from pressure drop
I think you'd be better off figuring out how to get all your psi to them then upgrading injectors. Bigger injectors will just cause the pressure to fall more.

Def agree. I don't know if you saw my previous posts but I decided to hold off on injectors until I figure out what to do with the system as a whole. FWIW I see "low" 40's at full boost, like 43-44. But yeah, still low after accounting for boost pushing back as well.
Good stuff to noodle on!

So I was wrong about which clutch pressure plate I have installed right now. I forgot the stock disc wouldn't fit with that so I put the stock pressure plate back in as well. Maybe it's not acrually worn but instead I'm just pushing past its holding ability...
Anyway... Was planning on getting a new ACT set, but figured I'd ask what others are running with high boost...

What I can tell you is that I ran an Exedy stage 11 for a few years but when i finally pulled it out , it was about to fall to pieces . The backing plate was tearing away where the springs pushed against it . I'm currently trying a locally built carbon/kevlar concoction .
I also tried the ACT HD years ago but really didn't like it at all .

I don't have enough miles to make a differance but I'm liking my exedy hyper single. It looked well built and pedal feel is stock. My wife couldn't tell a differance.

How bad is it to reuse the pressure plate and flywheel if they are not warped, just break the glaze with some sandpaper? I'm thinking of trying it with a new ACT disc while I do some research on a permanent choice...

Rx-8 clutches are weird, I have driven a few that are super stiff from the factory and yet mine and others are really soft. Then I have driven some with the ACT HD, Exedy Stage II, etc. that were everything from soft to hard. Hoss's Carbonetic setup is not stiff at all.

Well shoot, I mine was heavy as well but I thought heavy pedal was due to the HD Wouldn't anything with more clamping force be heavier? I had no noise. Until the disc went

There are def. HD clutches available with stock pedal feel.

Yep, that's what I was running previously. The pedal was definitely heavier with it for me, but not bad IMHO. I just assumed it meant it was stronger
My pedal had the typical failure about two years on that clutch and it went downhill quickly after that...

When i tore the car down it was a stock flywheel, clutch etc.
But after this install and a good pressure bleeding. I dunno to me it seems damn near stock. Maybe a tad heavier but nothing really notable.
