If going to go bigger injectors would an upgraded fuel rail be necessary?

 

Not unless your going for huge power. Like 450hp and up. I'm sure someone knows the exact magic number. Put that money towards an up or downpipe. Or both.

 

I'm running 1000cc Injector Dynamics on stock fuel rails.

 

If you are running ID1000's out here, there must be a purpose. I have perrin top feed V2 rails for sale if you are interested, PM me. I'm also running ID1000's, I used the perrins for about a month and a half, they worked great. I'm using cosworths now, for different reasons but the Perrins worked great.

 

Im just upgrading to 750 and always heard of people upgrading injectors and but never heard or read anything bout the rails.....im only going for 325 whp and im just waiting on my shipment t to come in lol did I mention I hate waiting

 

Stock rails flow enough for 500+hp, all you need to do is bump up the psi a tad. However, there are other reasons to run fuel rails, but most are detail stuff that wouldn't be important for such a mild build.

 

Right on ty all for the education .... that's why I love this forum
