actually i have been considering altering our blueprints to accomodate triple. The entire problem with this is the displacement of the surge tank. It doesnt serve its funtion very well if its full of bracketry and fuel pumps taking up all the space, and you only have just over 4.0" diameter opening to work with... cant wait to show you guys what we got going on

How will haveing a decreased displacement in the surge tank affect the car?

If you are gonna do a triple, i would be first up for that, you keep teasing me, lol

We have tested dual Walbro fuel pumps on a Toyota Supra up to 990rwhp.

Seen multiple Supras with 900whp+ with just dual 255 pumps also.

I have been around my fair share of high horsepowered vechicles, and have seen as well as heard of stories of the walbros giving out. The supra guys are pretty stuck on them and usually find out the hard way when one of the two fail, you end up maxing out the injectors thinking thats the problem, only eventually finding out one of the two pumps are gone. A buddy of mine is having great success with the denso line of pumps, which are also drop in units. Just putting in my 2 pennies, and hopefully helping someone out in the long run.

Actually I agree with this. The walbro pumps are pretty much the most popular due to the size and cost of them. An in-cabin fuel pressure gauge is an ESSENTIAL when using two of them.

The bosche pumps (such as the stock 300ZXTT pump that can handle 600rwhp itself) are nicer and more reliable, but cost more money and are physically larger, making it more of a chore to use.

I have been looking at the denso/bosch pumps too but didnt know if it was a viable option b/c of the size. I have seen the walbro failures first hand and would rather use the denso/bosch pumps if possible.

i believe we have space for 2 bosche with the way ours is laid out... however the cost needs to be researched. twin walbros is definatly cheaper because everyone already has 1.
