61.9/155 or 74/181 - ~18psi - upgrade to the 7.00228.51.0 and get a tune - ie: no need to change filter/reg.
65/181 or >19psi and you need to go with some 550cc injectors + fuel pump + tune but still keep your filter/reg. but your hitting 400-450 bhp and 300-350rwhp
HANG ON!!!!!
Apologies, if I have put any Walbro users off side.
good prices for a 7.00228.51.0 appreciated.
I found one in Aussie for AUD$375
here a little exxie for my taste tho.
This statement isn't accurate. There have been several here with 61.9mm pulleys that have removed them due to running lean even with the Pierburg pump.
