I guess i forgot to mention my walbro is intank dont have an inline pump. I will be using meth with a dual nozzle setup.

 

meth will help a lot. i got right at 500rwhp before pressure started dropping. 4.8 12#boost and no meth.

 

Mine took me to 11.22 @118.7 last night.

 

Wow congrats! If i ever get mine that far ill be completly satisfied. I talked to a friend yesterday and he made 440 rwhp on stock injectors stock fuel pump with just meth went 12.0 1/4 mile so i figured the walbro should get me to 500+rwhp

 

My in tank walbro pump works fine for me.

Im around 600 rwhp in the cool weather .

You will be fine.

 

Congrats Bud!!!! Thats movin!!

 

return system will probably get a lot more out of it.

 

im 650 with a intank walbro hot wired and meth...works great for alot of guys

 

Ill be using a 255 racetronix kit with my 5.3 and 70mm. Going to start out at 8-10psi and eventually down the road 12-14psi. Like the others have said, a RETURN style fuel system is key for these to work well.

 

Just remember, if u go lean, you go boom. It takes milliseconds.
