built supercharged t/a almost finished few ? Hey everyone I have a 97 trans am that i have been working on for the last couple years. The car has a fully forged 9:1 355 with trick flow heads, comp 224/236 cam, headers, 3" exhaust with cutout, 58mm throttle body, ported intake, egr and a.i.r. removed, vortech s trim pullied to the max (have been told that it should make about 14lbs?)front mount intercooler, mondo bypass, single walbro 255lph with racetronix harness, 60lb injectors, in car fuel pressure guage and wideband and a mail order tune from pcmforless.com. I just finished it hasnt been on the road yet. I just have a few questions before i get it dyno tuned to save me multiple trips. Will the single walbro be enough or should i upgrade before i bring it up? Bryan from pcmforless said he made 600rwhp with a single 255, what about a kenne bell boost a pump if it isnt enough?( just seems easier than dropping the tank again and trying to rig up another walbro, and have heard that needs an aftermarket fuel pressure regulator beacause of increased pressure.) I live in dover delaware the two shops close enough that i would trust tuning this are f body central in baltimore and jds auto repair in PA (bryan herter from pcmforless would be doing the tuning) anyone have experience with? A lot of you guys have similar setups in here are there any other problems you think i might run into before i make the trip to the dyno. thanks a lot - brian
You will more than likely be out of pump. I would spend the money and get an A1000 from Aeromotive and their regulator. Take a look at my build in my sig and that may give you some ideas.
Good luck!

fuel system will definitely not like that set up, should invest about a grand more and make it right the first time...then if you go with a bigger blower in the future you'll be set. A1000, Aeromotive Regulator, Rails, Either Cooler or Electronic Controller (or both) and the plumbing...you'll honestly be over a grand but it's very nice stuff (both beautiful and functional) and you'll be kicking yourself in the *** when you have to do it anyways.
Ask the shop tuning the car if you need more pump...which you most likely will. Sounds like your going to max out the SC so you'll need more fuel than a 255 can pump...Why not just to 2 - 255 in tanks?

I will be in a similar situation when I install my new engine. I did a lot of research on the subject, including the external pumps and the boost-a-pump mentioned in this thread.
I have decided to bite the bullet and go with a dual Walbro setup, either like the one MightyMouse built in the sticky in the Fueling forum (my preference) or something like Lonnies Performance sells.
I just don't like the added cost and complexity of the external pumps, and the boost-a-pump only increases voltage to the pump and is expensive to boot.
The aftermarket regulator you mentioned is called a boost referenced regulator. Do a search in the Fueling section and I think you will find lots of info.

ok
dual walbros- $100 for the extra pump probly around 50 for the rest of the setup. And doesnt that need an adjustable regulator? theres another 100. plus all the hassle of either taking the tank back down or cutting a hole.
aeromotive- $350. tank sump $?. filter $? fuel lines and fittings $?
kenne bell boost a pump - $200. Whats wrong with it? Its what they sell with all there supercharger kits. (750rwhp gt500). Says theve never had a failure? I found a website where a guy has a racetronix 255 with the boost a pump on a corvette thats supporting 800rwhp.
am i missing something?

I think these systems are running over $1000, more than I want to spend, and I don't like the idea of running all those extra lines. More things to go wrong, but again, that's just me.

The first two options do not do this, and it seems to me that it would be safer for the pump(s).
I just downloaded the price list from Kenne Bell's web site, he lists one for 230 and one for 250, depending on the current draw of your pump.
So for about the same price as the BAP, you could have a dual system that, IMO, would be much safer on the pumps. You run on the first one all the time, and the second one only comes on when you need it because of the Hobbs switch.
It's your car, do as you want. Best of luck.
