injector sizing

[VB242]

Thanks everyone!

I assume your making more than 300whp? 1300cc seems like alot for 300whp.


i've used a few of these but they all give different numbers, and I'm not sure who is and who isn't including ethanol in their calculations @ 15%,10%, or 0% idk. so I'm more interested in what CCs people are running even on an 8v application. But it seems like around the 850cc range is what i'm shooting for?

I'm running EV6 Siemens 800cc on my B23+T, I had an engine failure from the shitty EV1 connector pins getting loose and pushed out. I got them from Yoshifab special order. I've had it up to 28psi boost, no dyno so no idea of HP but it was still under 80% duty cycle. This is on E10 93 octane pump gas. I don't think there's enough head room to run this kind of boost with E85.

injector wire connectors are important. What you can find on the market are usually junk. I imagine Yoshifab selling the best he can find but are still ? Probably doesnt matter but how do you know connector blew your engine.

I think you misunderstood, I switched to EV6 injectors/connectors from Yoshifab after the engine failed running lean on the EV1 injectors/connectors that Volvo used oem. I found the fingers inside the EV1 connector pushed back on the cylinder that blew.

okay thanks sounds like 800cc might be on the larger side then, but I think that will be close enough how's your idle?

I'm using microsquirt setup for speed/ density and no amm so it idles fine.
