Jeremy, arent you running dual intake pumps? Do you still have the stock fuel lines? Dual intanks with larger lines should support 800rwhp.

I'm hoping dual intank pumps will do it for my turbo car. Is something like the MSD voltage booster necessary or is something like the Racetronix hot wire kit adequate?

With dual intanks, you shouldn't need any type of voltage booster.

My advice. If you are spending the money to make 800 rwhp do not slack on your fuel system. Spend the money on good stuff such as an Aeromotive A1000 pump and regulator, -10 feed line, -6 return, sumped tank, fuel cooler.....etc.

What happens if you run a A1000 and it dies under WOT? Same thing. Your fucked no matter what if a pump dies (whether you have 2 or 1).

Either way, if you have a Hobbs switch wired into your ignition somewhere, you can kill the spark after the pressure drops to prevent any damage.

Is yours sumped? My biggest concern was sumping the stock tank or having to shell out the cash for an aftermarket.

You cant see my setup at all, it looks baller.

Ive even got the Twist Loc blue -12 hose to the pump, so it stands out. But you cannot see it from any angle.

Pump Mounted.

Pump and Filter

To clarify a few items...

To address Walbro failures, I have been building double pumpers for Racetronix for over 3 years without a pump failure.

As for power capability, I have replaced A1000 pumps, that could not feed the motor, with my Double pumper kits. These have supported well over 900rwhp without any type of volt boosters. The A1000 is usually good for about 800 flywheel hp when it comes to forced induction EFI applications at elevated fuel pressures.

Sumped tanks definitely have their place, but for most applications that are street driven, the dual intank setup is queter, does not require a pump controller on the street & will likely feed most cars well into the 8sec range.

Since Jeremy already has the pump system, there is no reason to change it. Add lines, rails & regulator & it should meet all of his needs.

I have a Ricks stainless tank in my second gen running two gs340 walbro pumps ,the second pump comes on only when fuel pressure drops, done with hobes pressure switch, running two 6an lines to a y block than a 8an line with 6 an return, my ls-7 has 711 flywheel hp works great
