Max boost on 93 octane with a TVS2300

Wondering what everyone's had luck with with their TVS2300s on 93 octane. I'm currently running a 3.6 pulley in mine, for 7.5Psi of boost with my ported lower manifold. I have seen a spike as high as 8.0, but that's only at around 6300-6350 RPM. I have a 3.4 handy if I can get away with 9.5psi on 93 octane. I believe I have the fueling available to support the power. Looking for opinions by those experienced with their own TVS2300s if possible.

I run 9-10lbs on 93, so far so good for about a year now.

I assume your talking about stock motor including cam. I run 10-11 psi no problem.

I'm not running a cam, and I'm not running long tubes, just no cats on stock manifolds. The only thing holding me back is the injectors, I think i'd have to switch to 60s from the ZR1 injectors (52s). I'm at about 90% on the ZR1s, I think switching the pulleys would net another 40ish HP, but I'm not sure if I can afford the 60s right now.

14 lbs with a Centri or PD? And that's a stock lower end? Just curious.

Are you running a BAP with the fuel pump? Or just stock fuel pump?

Yeah man you have enough fuel, just might run out of injector. But you were already aware of that.

I was hoping to have enough injector to make it work. The ZR1s are supposed to be good for around 575 rwhp. I'm currently at about 90%. I wish I could get a 3.5 pulley to get it to 8.5 psi, I'd for sure have enoughinjector for that.

Just save some money and upgrade injectors bud.. Pushing any part of the fuel system can cause some big issues
