I asked Scott to PM me the info on the tank. If its Aussie only maybe we can put Paul on it.

From what I've seen it's very expensive. If I can add a second pump to my existing tank for significantly less then I would like to go that route.

I am working with company now that is doing a billet fuel hat to run dual walboro pumps for our Camaro. I know for a fact that INTENSE performance has some experience with it in one of there cars, your best bet would be to call INTENSE and talk to them.

how far will a simple boost a pump take a g8? if stock is over 500rwhp i would think a boost a pump would get us close to 700rwhp.

I'm pretty sure that Wreckwriter ran out of fuel around 500 with a BAP and his Pro-Charger.

today on a dynojet with 6-7psi i was at 485hp and 11.5 a/f ratio. not running out of fuel at that point. no meth, no boost a pump.
3 days ago i was running a set of 60lb injectors at 70%dc while holding over 50psi of fuel pressure.

Thats what I had for my car in fact there is still one I bet sitting at Harrops place here in Michigan. Long story short I kept getting the run around as to when it would be here and then when I pretty much was deciding to stop modding the car poof it showed up in the US with no warning at all. If any of you want to try it I can work with you and Harrop show you what needs to be changed ect I'm sure they would like to get rid of it and I'd be glad to help!

I have in my garage a second stock fuel tank that I got to have a fuel system built. I thought that the plan was to run 2 stock fuel pumps that would be good for around 1000hp. Anyone know if the dual stock pump idea would work? Obviously you would need extra lines and such. Looking for guidance on this.

I'm actually not out of fuel right now. I have a little room to grow but not enough for me to feel safe. I don't want to keep Magnavolting(new verb) my fuel pump.

What size is your current pulley Nate?

Mine was out of fuel with a KB BAP with a 2.9" pulley. Plus I'm on my forth fuel pump. One thing to note when N/A is your fuel system doesn't have to fight the boost pressure and their isn't any supercharger drag on the engine. So you will run out of fuel first on a boosted system.
My supercharger can "drain" 100HP from the motor just to turn it. That 100hp is lost but the fuel is still used. And 10 psi pushing against your injectors isn't helping either.

My charger is effectively sold, so no need to keep it quiet anymore.
As far as reliability of the twin pumps; 3 weeks no issues. No fuel starvation, no low level issues, and no pressure drops.
VegasNate

What size is your current pulley Nate?
3.6" front pulley, overdriven rear drive making 8lbs of boost. I have yet to see the fuel pressure drop below 60lb so far.

I am looking at getting a twin pump tank for my Commodore,but i'm not sold on the idea of 1 pump per bank.If 1 pump dies,then that bank dies,especially on a blown car(which mine is).
Am looking for other alternatives from the US right now.Any help would be great.
ulakovic22

All the twin pump setups I've seen Y in the tank and deliver to the rail. I don't think I've ever seen a "pump per bank" setup before, mainly for the issue you stated above, there is no room for error.

Mine runs forward then splits into 2 lines with one return as well
ulakovic22

My BBC T/A runs in parallel as well. One line to the front then Y into the rails, then to regulator and single return.
I contacted VCM and they want ~$2,000 plus freight for that tank. I'm looking at it, and wondering, is there some reason we can't just cut a hole in the stock tank and add a second stock fuel pump to it? It looks like it would be pretty straightforward to me, and a heck of a lot cheaper.

Its closer to $2600 actually there are some changes that need to be made for the G8. Harrop had to modify and create parts to get the second sender into the tank unfortunately its not that easy I've seen the CAD for all the changes.
The G8 variant is now available from VCM, and has dropped in price.

With both pumps being internally regulated, probably so. Aftermarket pumps dont like the factory style spring regulated bypasses
hmm, that would be bad ass. i wonder if it uses a 2nd stock fuel pump modual.
Yes ... it uses the original pump plus a duplicate.
The tank is machined out and an aluminium insert fitted to simulate the OEM module seat/interface, then a couple of items are mounted to the aluminium for holding the second sender etc, an additional internal link-tube installed, then the second pump module is mounted, and an additional feed tube and special loom are added.
It is tidy, quiet & safe ... and conforms to Aussie design rules.
There are a couple of ~1000rwhp cars using this solution.

Would both pumps work all the time or is one on a hobbs? If both are on all the time, would it affect gas mileage or just higher fuel pressure?
Are stock lines going to support this or are we talking all new lines?
Both pumps run constantly. There is no effect on milage as the tune/calibration controls the usage of the supplied (constant) pressure ... the pressure is not higher but is maintained throughout the rev range (one pump will typically be unable to maintain pressure at higher rpm).
The usual practice is to install an additional OEM fuel line (cheap & good) that fits parallel to the original & joins to the fuel rail with an OE flex, thus doubling the supply capacity and looking OE.

Gotcha thanks for the info.
I was quoted $2400 plus freight about 6 months ago when I was looking. I'd still really like it, but I have a feeling freight is going to be murder...
parish8

Pretty much. Kind of a bummer, I like that much better than the options we have stateside. Less moving parts, cleaner install. Such is life.

I can only comment on Aussie pricing at this stage due to the fact that we've not looked at freight pricing to the USA on this product.
Indeed, supplying to the USA would possibly be prohibitive as our pricing is based on a changeover basis.
In any event, the cost here is AUD$2400 and includes all parts required for the system to bolt directly up to a Harrop (or other) positive displacement supercharged engines. If used on an NA engine billet fuel rails are required.
Any further info needed, drop me a line.

Everyone,
I was in a situation when I had the DOD valve train eliminated and upgraded the cam where the stock fuel pump was inadequate. The speed shop that installed my D1SC and cam did some very similar research and found that the stock fuel bucket can be modified to accept a single Walbro high output fuel pump. If you want more info you can talk to Tracy Scott at CincySpeed.com. The cost was less than half that of dual pump systems and is also less complex. I'm running 574rwhp and no problems with fuel delivery. See my sig for the build up info.
