what's needed for a 500-600whp setup?
new fuel rail, what size ID?
FPR
Change stock fuel lines?
walbro fuel pump good enough?

 

Don't think a walboro 255lph will work for 500-600whp. If you change your stock fuel lines, you may as well get an external pump such as the SX Performance or the Aeromotive A1000 .

are you sure about that?

 

For the walbro you need the high pressure one. Most places only sell the low pressure 255.

You need the walbro 255 HP, new fuel filter and 1000cc injectors and you should be good to go. I made 603 whp on that setup

 

double post

Where you limited by fuel or turbo?

 

It was the head and it was on pump gas so it wasnt pushed to the point of destruction

 

buddy of mine made 575whp on race gas with 950cc injectors and a 255lph so it can be done, but I dont recommend it. he was also at 97% duty cycle.

 

i made 620 on stock fuel lines and a walbro hp...

 

585whp , 1000cc XS regulator 8an lines Walbro 255HP 10guage feed to pump via a relay , held pressure w no problem. Over 600whp would be smart to run a bigger pump, injectors, feed/return line not saying it cant be done- just my opinion.

no aftermarket fuel rail or FPR?

 

612hp, walbro 255hp, Precision 1000cc injectors, AEM regualtor, stock lines, Edelbrock Rail

 

what kind of #'s are people making with the walbro 255 low pressure?

 

bump for the same question myself.

 

there is no need outside of ricer ******ry for an fpr or rail under 600+whp
got cash to blow? do it
otherwise stock system + 255hp with a direct 12v and 1000cc injectors = it

 

im supprised nobody made 500-600 hp on 750cc or 800cc injectors.

 

530whp stock fuel lines ,stock fuel rail and fpr,single walbro 255hp and rc 750cc injectors with 91 duty

 

The normal walbro 255hp can be used. All you need to do is simply add another relay on it. I'm sure a few guys on here know what I'm talking about and can help you.

sorry thats just not possible with 750s at stock fuel pressure.

500 to 600 can definately be done on 1000cc injectors with the 255, if you really want closer to 600whp i would invest in a good sumped tank fuel system.

 

Is there a bigger intank fuel pump than the Walbro? I heard Endyn makes a modified Bosch pump that fits in the tank.

 

alright akira, stepin up the power level!
have fun

 

it can be done, but at that level, why skimp?
