Hey guys, im going with a garret gt3071 turbo, aiming for 400hp with 18-22psi of boost. I've got 80# injectors and was wondering if I will need the return style fuel system? What can our cars handle fuel wise?

 

I would go ahead and get it. The fuel system seems to get lean out right around 350 hp from everything I've read.

 

I'm running a 50 trim garrett which is about a 45 lb/min turbo at 22 psi with 80 injectors. I'm running at 11.5 afr and at 7,000 rpm I'm at about 65% idc. If I had to take a guess I'm probably closer to 330-350 whp. I think you would be fine at 400 whp with just the 80's. Now I will say that I have waiting to be installed the OTT return style fuel system with the walbro pump so I can get the idle issues out of the way and have some headroom later when I go with a bigger turbo.

 

get it... its well worth the money... plus its one less thing you gotta do later on if you ever wanna get really crazy.

 

Agreed
