From what I've seen you have several options.

Run them in series or parallel.

If you run them in parallel you have a good bit more work ahead of you, but most people run them in series (inline).

Basically out of the Wally, into the 044, and into the rail and back.

Up to you to figure out the lines/etc needed.

Hence, why to me the BAP seems like a much better idea.

 

Buy the BAP direct from Kenne Bell ... they are very good to deal with and will ship it right away.

Well maybe I am misunderstanding this but it seems that the Walbro/BAP combo is still only good for around 80-90psi (with a modded walbro pump according to Tony) Jeff said on Jacko's car he rewired the walbro with a seperate relay (which i already have done) and at 590whp at 50psi base fuel pressure he was at 75-80% IDC, according to this dyno graph of Jacko's Car

he made 580whp at 19psi on a 35R (or 69psi overall fuel pressure), so im thinking to hit 650whp thats another 7psi of boost (using 1psi=10whp estimation) which would make it a total of aprox 76psi of overall fuel pressure, which might be pushing the single walbro to its limits, you may have the flow capacity, but it seems like the pressure isnt going to be enough .... maybe i have this completly backwards...

I dont want to ever disrespect or second guess Evans-Tuning, he is my go to guy for tech questions, but i just want to grasp this concept alittle better....

 

W/o arguing over numbers I'd think it would be more like 15whp per psi in the upper limits of that turbo.

So you would would have 10psi to play with. In that case Jeff is right in saying it would take the 35r past it's limit and still have a few % to go on.

700whp may be a pipe dream on a BAP + Walbro, but it's a great alternative to most setups while still making 650whp-675whp.

I plan on seeing what it's capable of this spring.

 

granted, i will HARDLY ever be running the car at 650whp, just for dyno numbers,bragging rights, and weekend fun (rarely) but is the 10% window something that is safe? dont you want alittle more safety cushion?

 

It's all about knowing your limits.

When tuning you can watch fuel pressures, afr's etc.

Say the car makes 675whp at it's MAX, back it down 10% and call it a good day.

Thats what I'd do.

 

It's funny...a few months back I was talking with my cousin and we were discussing the BAP setup, but quickly dismissed it as it wasn't a "common" solution with Honda's. Now it has come up again and I figure WTH, I'll jump on the bandwagon and see what happens.

I figure if it gets me north of 650whp I'll consider that a win, especially for the price and ease of installation as compared to dual walbro's or adding a secondary external pump w/lines and fittings.

I spoke with a buddy who has an 03 Cobra. He's been running the BAP for some time, and has been happy with it.

W/that said, he pointed me to this site and said he bought his from there, the price seems ok, and he said the customer service was top notch, so I'm sharing it here with those that are interested.

I'll be sure to do a writeup when I get started on mine in the next few weeks.

There is a pin you can push in on the Walbro pumps to bypass the relief valve (you must know which pin to push in though as to not mess the pump up) but the max fuel pressure you will ever get out of a Walbro pump is roughly 85-90 psi. The max fuel pressure, no matter how many Walbro's you run will always stay the same but the volume of flow will increase.

 

Thats what I've heard, but I haven't seen a diy on what needs done.

I found this.
