Twin turbo 69

[1badss]

I'm building a 67mm twin turbo on my 69 Camaro I was going to run a external pump. Ricks tank is building me a tank with twin pumps in it that's inside of the tank. So it's real clean looking and only one pump is running until the 10 pounds of boost and the second pump comes in. Selling the other pump that I was going to use

Sounds similar to my setup. What Intake pumps is it using and what are power goals?

Yes twin CTS-V pumps setups.

Funny this just got bumped. I maxed twin v pumps recently and just received my new ricks setup. Twin 525s are replacing one of the v pumps. Will keep the v for primary but at 2psi the 525s will start to flow. I’m hoping this will be enough to cover me to the 12-1300 wheel range.

Curious what you guys are doing with these cars, to make use of that power level? Definitely impressive numbers !!!

I just enjoy the power. Texas is full of long straight roads, so it gets used a lot there. I turn power down as much as I can at events like LS Fest / Autox events. My skill level and that power is a sledge hammer for a finishing nail. I put drag radials on it and take it to the drag strip as well. Still sorting it out and on 15psi, it's gone 9s @ over 150mph with plenty left to go.

The new setup mentioned in the post you quoted is working very well, no issues with fuel support now and the car is around 1000rwhp right now. I'll get around to turning it up a bit, but want to change around the WG control a bit before going much further.

You could also use a Radium external surge tank with triple 525 pumps with one small intank pump feeding the surge tank. That will support 1500rwhp on e85

I'm running dual 450 Walbros... quiet and will support well over 1000rwhp on e85. Dual 525's which are nearly the same size will support over 1300rwhp on e85

I use to fight one hole summer of vaporlock from fuel warming. Where running multiple pumps at my customer '67 Camaro. 750hp (+1500ftlbs ) 615cid EFI na -motor. Run with two Bosch 040 pumps. Then changed to Walbro 475. Can't drive highway with just one pump, starts to shoot at pipes, need to switch other on too. Then its smooth ride.

Now I'm about to turn it to twin screw charged with 4.7L Kenne Bell and custom intake. Going with Aeromotive mechanic belt pump, same as my Plan Bee.
