Reliable 450whp fuel setup
Hey guys i had a question? on my 88 TII, my fuel setup is:
800cc Primaries
1600cc secondaries
Stock Fuel rails
Stock Fuel lines
Stock Fuel pressure regulator
Walboro 255lph fuel pump
what out of this setup, would i need to change so i can support 450whp reliably? i'm probably going to be pushing about 17 psi out of my masterpower T-70 to make this kind of power, but i want to make sure i am Squared away with my fuel setup.

for me a reliable set up with growth for the future in the mind, just incase you want to surpass 450 in the future... wich everyone always does.
dual walbros (one pump per rail -6 lines or -8 single fuel line)
850 primary
1680 secondary
and adjustable regulator
E85

Out of curiosity, at what hp level does the fpr have to be upgraded? Under the conditions of walbro, stock rails, aftermarket injectors. I know this may be a retarded question because that's what a fuel pressure gauge is for to find out.

i dont trust walbros.
they work fine but ive seen 3 pumps on 3 different cars go out for no reason. they're kinda hit or miss in my opinion.
I personally use this one:

kinda of an upgraded walbro. its a drop in replacement too.
Ive had it in 2 different FCs(same engine) with no problems. Its pretty reliable.

however, the age factor is something to think about. not necessarily for dirt and grime but for old fuel turning into varnish and the hoses cracking and leaking.

for -8, yes. or get a -8 to-6 barb fitting to make the -6 slip on the stock fuel rail.
or you could just get aftermarker fuel rails, use AN fittings and not worry about leaks. more expensive though.

^+1 but not neccessary IMO unless your keeping further upgrades past like 525whp or more in your mind. then again, if your goins as far as 450 you then there really isnt anything stopping you from buying a 044

No they are not. Stock is 5/16"
Yeah, maybe if the car is sitting unsed for years at a time. Everytime you turn the key fuel is flushed from the lines. Seems like kind of a moot point.
Whinebro's are the LEAST reliable pump on the market. Go talk to a bunch of guys that have been in the business for YEARS and worked on a TON of different cars. Not just some kid on the internet that bought one pump, drove his car for 10k miles in 10 years on the same pump.
This is a fact.

Im no kid buddy. i have ran over 11 different Walbro fuel pumps, inline, and intank on my personal cars alone. Not counting all the ones i installed for people. Never a problem. Maybe its you...
