does anybody know how much rwhp the lonnies dual pump system can support....I think the system is twin 255's and I have 100lbs injectors..
I have seen people say 1000rwhp but im not understanding how that's possible with what looks like a -6an supply line and a -4an return

comments?

I've got the Lonnies setup on my ride. I am not quite to 1000hp (probably 925ish) but pretty darn close and I am not having any issues. Also, I have a -8 feed and a -6 return I believe, feeding ID1000's. Lonnie is a little bit difficult to get ahold of as he has a day job and I believe this is just a side gig, but if you need his number shoot me a PM.

left him a message ....I measured my line size and no way its a -8 and its from Lonnie's kit....

FWIW I have -6AN lines on my car. I made 940 WHP and could easily get more aggressive with the tune and make 1000+ WHP.

-6 lines really do hold plenty of fuel.

Mike, you really only have 1 6AN feed line? It costs practically the same to run bigger and have less restriction on the pumps

Spoke to Lonnie .....told me the twin 255 will support 1000whp.....and recommended I move the vacuum line from the brake booster to ahead of the throttle body...also told me to crank up the pressure to 75lbs
As far as his lines they are -8 but look smaller due to being Teflon liners instead of rubber liners....also avalible is a upgrade from a 255 secondary to a 340... Cheap ..like 125$ for an extra 100hp headroom
