Great work, given me a couple of ideas for my vh ls1 turbo build

Not to much to report

just been plumbing the catch can and smoothed the rocker covers (removed the coil bracket mounts) and painted them wrinkle black.

Got a VR V8 long range fuel tank, cleaned it up and painted it, had to modify one of the VR tank straps to suit the VK.

Went with the VR tank as it has the return line built into the pump/sender unit assembly verses directly into the tank on other models, and I had seen quite a few where the internal return hose had perished and broken, so returned fuel would not be helping refill the intank bucket.

The plan is to fit a Walbro intank pump to feed the surge tank.

Ignore me if im wrong here but wouldnt you be better with a low pressure  lift pump in the main tank if your running a surge tank there wouldn’t  be a reason  to run such a big pump prior to the surge would there afterall youll have a pressure pump after it.

wouldn’t  you be running the chance  of aeration in the  fuel inside the surge force feeding it on start up and when the main pickup gets air

^that’s the way I understand it also, in fact with mine at first I (wrongly) ran a nice Holley billet pump as the lift pump.  It died after a little while as it was basically sitting there running flat out the whole time trying to pressurize the surge tank, it got hot and crapped itself.  Actually you only need a low pressure pump for the lift.  All its doing is quietly sitting there keeping the surge tank nice and full all the time, but not under any pressure, its the main pump that does the work when you step on the gas.  Great build btw, not criticizing at all, just trying to share my stuff ups to save you from them

The intank pump will have no regulator, so in effect it will have low pressure and high volume and returns via the factory fuel pot which from my understanding creates a venturi effect to further fill the pot. So as long as the main tank doesn’t get too low it shouldn’t be a problem.

Its gonna need a reasonable volume to keep up with two 044s feeding 1000hp.

I have a similar setup on my VX, but only run the factory intank pump with regulator disabled, to feed a surge tank and two 044s, seem to work fine.

I guess the factory VR pump would be enough to keep the surge tank topped up, but being a used unit of unknown miles, I would prefer a new intank pump.

I’m always happy to here what others have done, that’s the beauty of these  forums, we all learn from each others builds.

I totally agree, to me this is where forums shit on fb.  Unfortunately on fb you get anybody commenting, and you really have no idea their experience.  At least on here you are only getting those of us that are interested and (hopefully) have half a clue.

Certainly nothing wrong with making sure all of your fuel system is 110%.  Especially with a turbo car, last thing you want is it leaning out and going pop (touch wood).

Just remember though that lets say you have a 3L surge.  Even if the lift pump failed totally, you have 3L of fuel in the surge to draw on.  Its not hard to calculate out even at wot how long that will run the engine for on that.  Prob enough to do a quarter run.

Having said all that there are a million different opinions on fuel systems.  If you are chasing a genuine 1,000HP (like I am one day), I would suggest you chat to someone in the game like Jack Hayek at Earls in Qld, (but I am sure there are others), but Jacks great.  A fuels system for a boosted 1,000HP car is a key part of the puzzle and because of what happens if you don’t get it right is something worth spending some time on imo.

My VX is making around 950hp flywheel, the fuel system works great, so I’m sticking to a similar formula, but will be running bigger fuel lines -10 feed and -8 return plus a 2000 hp capable Turbosmart FPR2000 regulator just incase I add a third 044 on a hobbs switch and convert to E85 down the track.

Nice, I mean if what you have is proven, why change it.  This things gonna be a weapon.

Progress has been slow, but just had some custom coilovers built by Suspension Tech.

using Koni rebound adjustable inserts, soft setting should allow reasonable weight transfer for drag strip, and hard will be plenty for powercruise style track events.

450 lb springs and heavy duty adjustable top hats.

Heaps of tyre clearance now for the 20s as well, so ticks all the boxes.

The feed from tank to surge is low pressure. Need big lift pump

nice fab work looks good. shame there is no better pic of the new lower radiator support. i assume you made it with some rectangular section around the 10mmx30mm?

Car is at panel beaters at the moment getting a few bits tidyed up before paint.

will get a pic when I can, but I believe it is 50 x 25 with a tube back brace.
