2300 Heartbeat pulley options
The Zo6 upgrade kit comes with 80mm which produce 12psi. The next option Magnuson offers is the 70mm which increases boost additional 2 - 2.5psi. My search results of forum is about half the 2300 folks install the optional 70mm. For only $79 it seems like a great easy upgrade. Why don’t more people go with 70mm? I understand it will generate more heat and cooling upgrades may be required. Is this the only downside?

Magnuson does have a 75mm pulley (Part# 57-03-08-075-BL)
To answer your question, I would guess that the stock LT4 fuel components will run out of fuel with 70mm pulley, unless the car is supplemented with Meth injection or running a cam with bigger fuel lobe

I have a bunch of experience this past year on my LT1 Camaro. I upgraded the fuel system to LT4 fuel system (hpfp, in-tank, and injectors). I also added a JMS voltage booster and added the e85 sensors. Finally, I did add the cam with increased fuel lobe and long-tube headers.
The LT4 is lower compression, so you will have to run more boost to make the same power, but will give you a reasonable idea. I didn't complete my testing/tuning because we ran into winter, but this is the info for now:
Everything running pump e85 (about e70) in my a8.
85mm - 8psi - 715whp
80mm - 10psi - 745whp
75mm - 12psi - 775whp
70mm -14psi - low pressure and high pressure looked good. The fuel injector pulse width was out of room and we aborted.
At this point there are a few options:
1. Get the FIC injectors and run pump e85 to the mid 800's.
2. Add alky to mid 800's
3. Keep it where it is on the street and come up with a race tune wirh race fuel to mid 800's.
If you don't do the voltage booster you will run out of fuel on the low side first. If you address the low-side you are going to be good until around 800whp. . .then you have to address the injectors.
A couple more notes, I dynod on a load bearing dyno so the results will be conservative. Also, I have an automatic, so a manual will be a bit higher.
i can do aome research, but I believe you will be limited to around 650-750whp on the stock cam.
I used Ted Jannetty at Jannetty racing to go through everything and as it relates to the Maggie, the guy is an absolute genius. I'd recommend giving him a call because he fan answer any question about this subject easily.

Since my Vette is the daily driver, I am not going to do anything to make the exhaust louder, I will add the Maggie or one of the other blower setups, but that’s it. So the Lt1 fuel system will cap out around 575-600whp. That’s going to be it for my Vette.
On the Camaro I will tap out as soon as I have a 9sec slip for the vert. The Camaro is already a heavy car, but the convertible adds another 300lbs. . .so it’s right around 4000lbs. I think that with the drag pack I will be good for the 9’s as it sits with pump e85 and 10-12psi. If not, I will up to 14-15psi and make it with no problems.

Thanks again hogurt. I took your advice and reached out to Ted. He is very nice and knowledgeable. I certainly appreciated him taking time out of his day to answer my questions. In short, it's going to be difficult to achieve close to 700whp on the stock fuel system and pump gas. 12-13 psi should be safe. I will use the 80mm to get boost level and have the 75mm in reserve.

I think that belts belts will require some testing regardless (to make it just right on your car).
