3 way air manifold drilled inlet to 11/16 and tapped 1/2" NPT (for -8AN) $6


Some minor work inside to unshroud the ports, it was originally intended as a splitter not a collector.

I know I said I wouldn't but I did the trap door mod on my own ws6. I went to pull the tank and my TRZ anti-roll system is welded in the way!

Here is the set up donated from my formula, twin walbro's untouched in like 6 years got the car to where it is now.

Out with the old..In with the new! 3 brass 1/4npt to 5/16 barbs $6

3 gss340's from New Era Performance $300 shipped.


The fit.. no tighter than the twin pumps.. doh! Fun to get the level float in tho.


The results.... in [SIZE="4"]HD[/SIZE]

 

That looks serious!

 

That is insain! Are the three pump setups more for a backup? You need two and having three is incase one fails, or do you need the flow from all three? Just curious.

 

not at all, failure has nothing to do with it. they are good for about 600hp each and i plan on making more than 1200 so had to go with 3 this year.

 

Are you going to run all threee all the time, or have them on a window when fuel pressure drops the next one kicks on.

 

You don't want fuel pressure to drop before the pump kicks in. They will be TPS referenced. Some also reference boost to turn the other pumps on.

 

Very nice, to bad you go through alll that work on such a nice triple and then butcher the **** out of the car with a friggin trap door ..

Takes 30 minutes to drop the tank if your flying solo people.. dont cut the **** out of your cars body because your too lazy to take 30 minutes to drop a heat shield and take out a few bolts.

 

if you would of read he said he had suspension welded in the way...

 

scrolled right by it when I was looking at the pictures, sorry missed that..LOL
All is good then! trap doors are my pet peave...hahahaha

 

its honestly not a problem when your modifying the car like this... its not like its a collector type car anymore...

 

true very true but still thats about as hack as you can go

Seriously.. cuttiing a hole in the body to swap a pump up is as butch as it gets.

If you dont have choice like MM you gotta do what you gotta do... but otherwise its just stupid to do that IMO. You can also make an argument for safety reasons as well if you wanted to but I guess but to each his own.

 

thats looks good MM. is there any change on the electrical side of it?? i was wondering because of one more pump=more load.

 

Thats what i would like to know also! Fuses would have to be changed but what about the wiring? and such...?

 

Looks ok for a guy who doesn't know what he's doing! ha

 

do you have a plastic or metal tank?.. it looks to be a 98 tank to me...

 

where do i get the manifold thing

 

eatlead i have been doing hackjob work on my LS cars since 01. you shouldnt be so surprised I know my left from my right and removing a metal tank is a 2hr job on these cars without bars welded in front of it.


the 3 way manifold can be found at most tool or home improvement stores. or google 3 way air manifold. reminder that it comes wtih 3/8 npt inlet which i enlarged.

the car will run on one pump as usual out of boost. when i floor it the other two will cut on with tps as current.

the second pump relay will be upgraded from 30 to 40amps and the third pump will get its own wiring over to that relay and a fresh ground. fuse will probably go from 15 to 25A

this is a metal tank car.

 

here's the rest of the job

avk threaded inserts may be a newb move so please excuse the butchery






the trz issue... slight possibility a plastic tank could make it out.

 

Thanks for the writeup, after seeing that pic, I sure as hell don't blame you for doing a trap door. Besides almost every car made today (especially European) all have trap doors from the factory.

 

Sweet, i wonder if this could be done with a 02 tank (plastic)? I did my own DIY double, the best I recall, it seams like I would have to remove the entire bottom of the plastic bowl.
