еще раз Hello

stock is 160 lph

255 тебе хватит с головой

Привет.А Caroll из Blowerworks говорит,что надо ставить 2 по 255.Один в бак,другой снаружи.Для чего два?Давление или объем топлива недолжны измениться.А длячего тогда?

I don't know what that says.... but I saw Blowerworks....255.... and some symbols.. if ya talked to Greg.. you are on the right track.. also Brand-x is a phenominal guy to deal with.. can't say enough about either one of them when dealing with blowers..

ps.. for the max of the intank 255, I was able to squeeze 514/570 out but she was going lean very quick at the end.. this was at 14.5 psi and fuel pressure was I would not feel comfortabl;e running more then 500rwhp with a single intank 255 and nothing else. you may also look into the kenne bell boosta-pump which I have seen guys use successfully to 600rwhp.. but again.. when it comes to fuel......... after all my ordeals.. I would rather go overkill and have room left over a few hundred rwhp to grow then be right at the max output and run the risk of it going lean and detonating.

а тебе на 42-ых да 15 пси одного 255-ого ЗА ГЛАЗА. ПОВЕРЬ.

...а так с-дуру можно и десять насосов поставить - хуже не будет

один 255-ый = 600 нр
