Hi,
A friend of mine got a drag 1991 CRX with B16A high compression pistons, NOS and stuff...
anyway, lately after he've raised the NOS jetting, he've been going lean at high rpm, so i guess the fuel pressure is going low at high rpm, he decides to go for a 2nd fuel pump....

So is it better to put both fuel pumps in the fuel rail? or 1 pump in fuel rail and the other going to the NOS selinoid?

 

I dont think u want ur fuel pump in the rail... im not sure i understand what u mean...
Usally there is one intank one inline...

 

it's a drag crx, it has 1 small race tank... i*t already has 1 MSD external fuel pump going to the rail...

o.. well why dont u get urself an intank fixture and also use the external

Dont have a fuel pump going to the NOS solenoids its unregulated if u run it like that....
You either need to open up the fuel nozzles a little soo that they dump more or tune it for the amount of NO2 ur spraying

 

I would stick to one GOOD fuel pump. the downfall to having two pumps is if one goes out you will never know at idle/cruising rpm but you will find out at higher rpm when you destroy your engine!

 

what he said ... and scrap the MSD get a walbro 255lph HP
that wont lean out....
