What setup would I need to support up to 600whp?

 

Basiclly a Walbro 255 fuel pump, Kenne Bell Boost-A-Pump, and some 60lb injectors.. That would easily get you to your goals.

 

Do you not need a boost reference FPR? I'd like to keep it as simple as possible but how else would you compensate for boost?

 

You can compensate for boost by increasing injector pulse width. If you don't want to be running your fuel system on the very edge of it's capabilities, you can get a fuel system that works in tandem with the factory system and comes on under boost. A&A and ECS both make these systems. I am more familiar with the A&A since that's what I have. It will include a boost referenced regulator and a Bosch 420 pump and runs ~1100.00 I believe ECS system runs a boost referenced regulator as well.

 

I would add a RACETRONIX Hot Wire Kit for the Fuel Pump to this list and you will be good for a long time

Thanks,Matt

 

It was 2am when I posted. I forgot about that..

 

A/A is a very good system. it is what I also am running. Very nice and neat.

 

What year vehicle? I had the Racetronix setup and BAP and was running out of fuel well before 600RWHP. This was on a 2000 model with the filter and regulator together under the car.

 

And you did what to resolve it? Curious where people are going with these systems and solutions.

 

Mototron 60's, BAP, Racetronix Harness, and Walbro 255, have been used in hundreds (possibly more) of vehicles over the last almost 10 years. Typically they dont run out of fuel until around 650.

A secondary fuel system for 600rwhp is just not needed. Its too low of a power level to merit large external pumps, with boost referenced regulators.

 

I can verrify that 255 + KB BAP runs out of fuel at 650rwhp. I ran out at 652rwhp at 5357 rpm last summer on a Dynojet dyno.

I have the A&A system now and its much better now. I plan on attaching the BAP to the bosch pump soon since I'm after 850 - 900rwhp.

 

A&A fuel system. Now standing at 566/594 and running out of belt grip However fuel pressure rises steadily with boost increase (boost regulated fuel pressure regulator).

My changes:
Went blown, car made 480/420 with an underdrive pulley, 4.5lbs boost. Stock fuel with BAP.

Replaced the U/D pulley. Car made one pull?? to 523/480 6.5lbs boost. According to the tuner started getting piston slap over 5k rpms. The shop had just pulled heads and replaced because the timing chain they did not replace broke on the first blown setup. Also buffed out where the valves tapped the pistons etc. etc. Left that tuner only making 440/460 around 5k and was told not to go over that... No mention of fuel, no fuel psi gauge on my part yet.

Added a fuel pressure gauge and noticed my fuel pressure was dropping below 50 when the 'piston slap' started. So I made my own restrictor and limited my boost back to 4.5-5 lbs and viola!! my car revved out to 6k+ again.

Had the Racetronix harness and fuel pump installed. New Tuner BTW Different dyno 506.6/459.7 on a dynojet that reads very close to a Mustang. Fuel was starting to drop after 6k into the low low 50s, was hoping to take it out to 6600 like the original pull but tuner suggested against it.

Took it wayyyyyy out playing with a sprayed C6 That started the water seeping into a cylinder

Current setup (as stated above)- 402/D1/smaller pulley and bad belt slip 566/594 A&A fuel system, plenty of pressure still had Just waiting to get the slip fixed

 

I actually agree. I like to think my car is the exception rather than the rule, plus it is just my luck

To be fair- my BAP was used. It was hard wired for the 'full power' setting. I know it kicked on as I could see the pressure increase but I never measured the actual voltage, maybe it was weak?

I do hope to be well over 600 once the belt slip is fixed too
