Go big or??? Pump sizing
 

Running a Tanks Inc. tank in my 69 Camaro. Getting ready to purchase a fuel pump module for it.
I'm wanting to just purchase the largest unit they have, for future HP capability.

Question I have is, would there be issues running a large pump (PWM) at lower HP levels initially?

I'll be running a 6.0L twin turbo setup eventually (750 HP max), but am thinking about running it N/A for a while, just to get the car running. Don't really want to buy a smaller pump now, then spend $$ on a Larger one later, unless it will be an issue.

Here's the unit I'm looking at.

Also if, there is something better (there always is) I'm open to suggestions.

Thanks!!

With a PWM controller I'd think you're fine. I'll be using one of Carls Vaporworx PWM units on mine for exactly that reason. I'd talk to Carl to verify as he has systems matched to many different pumps and will give you an honest informed opinion if that exact pump will do what you want it to.

Thanks for the info and insight. I was looking at their website. Lot's of useful info there!! Controller costs more than the pump!!! But hey, quality costs money, and it's better than being stranded with sub par equipment :G-Dub:

I fully agree with Jody, what you get from Carl is a lot more than just a nice controller. The customer support is amazing.

I've been working with him on my car since the start and now have his latest upgraded controller as I went with a bigger pump configuration.

I have a ricks tank with dual CTSV to start with, and was EXCELLENT, until power turned up a bit too much and had to upgrade a pump. The low level fuel control is amazing.

I now have a CTSV pump as a primary so low fuel performance is still great, but have a Ricks module with dual walbro 525's in it, and if the tank is less than half tank basically, you can see the fuel pressure fall off. Not a big deal for autox, but drag racing and spirited highway driving, you want to be sure you have plenty of fuel.

There are a lot of options out there and Carl can help point you in the best direction for your build and your goals!

I'm not going to be anywhere near your power levels, so hopefully I won't need dual pumps, otherwise I'll be having to purchase a new tank.
I figure 750 max will be sufficient for what I want to do.
Thanks Will for the info!!

Honestly with that as a max, i'd look at using a V (or ZL1) module and replace the pumps with DW300C pumps. Get a vaporworx controller to control it all and let him know you're using those pumps. I think that would get you VERY close to 750rwhp and maybe even on E85.

Thanks, buddy. I bookmarked that page.

From a more budget minded perspective, I used the Tanks in unit with a 255lph pump with no problems. Dropping in a more powerful pump is a simple affair, easy afternoon job, and there are a lot of single pumps that will support 750 on gas.

The trade off with a bigger pump is noise, powerful pumps are loud, and you are going to cycle your fuel through the rails a lot quicker if you use a full return system.

The vaporworx system is no doubt the best way to go, but it’s 4-5x the cost of a tanks inc drop in system minimum.

Thanks for the info

Yeah, for me, swapping the pump is even easier, because I incorporated an access panel into my build.

A tanks inc 450 pump module is $340. That will support your hp goal.
+ some kind of regulator (~$150), you are about $500 in ignoring plumbing which will be needed for either option.

Vaporworx module is $430, which just controls the pump.
Not sure what CTS-V fuel pump module assemblies are going for. OEM modules look to be ~$800, aftermarket about the same.
The Tanks Inc tank won't accept an OE style module so you will need to weld in the mounting ring, ~$200 in hardware + installation.
So now you're ~$1500 in. (unless I'm misinterpreting the Vaporworx site)

There is no arguing that the Vaporworx setup is better. Really depends on your intentions with the car as to whether its worth it.
