Well the time has come as you can see in the other post. heres the bottom line. Car is my commuter. I dont want to kill the fuel economy. If I hit the 600rwhp mark and still around 18mpg Im fine. My C7 was cool with a SI Procharger. I switched up to a TI with long tubes and a new tune. Now I stare ar 14mpg on meth. I dont want to go back down that rabbit hole. I was thinking LT4 injects and a pump whether it be aftermarket or LT4 high side I believe

I believe a Maggie 2300 with a mostly stock car will get you around 550 WHP. You wouldn’t need to upgrade the fuel system at that point, unless you want to run E85 of course... And if you start turning up the boost, then you’ll need to upgrade the fuel system. I figured it was just easier to do the LT4 fueling at the same time as the blower install and that sets the table for future pulley swap on my Whipple.

My car has LTH and RF plus the 2300 dynoed 530/550 on 91 running the 1/4 11.1@ 126mph

I would, that way you can turn it up a little and have plenty of fuel. You don't want to push fuel limits on the stock pistons.

Thanks fellas. With that said wheres the best place to get the high side pump and injectors.

I believe DSX Tuning had good numbers on the injectors and HPFP.

If you simply add the blower with the stock car it will be in the 550-575whp running 7psi. With that setup your mpg will be just like the stock car when you are cruising on the hey. Obviously if you get into boost you are gonna watch mpg drop.

No. You do not need to upgrade the fuel to run in that power range. If you want to run more than 7-8psi, you will need fuel. I think I posted details when I was going through my setup and I outlined the exact timing for fuel additions.

Just one addition, I have this exact setup at 560 whp, and Ted suggested adding the voltage booster for guaranteed fueling stability near the top of the rev/hp range. I listened to him. The car has been flawless so far.
