gsr injectors
 

im am helping my friend tune his car right, he doesnt want to be homemade on this so no dsms for him. when getting a set of rc injectors, do i need peak hold or saturated? and would 440s be ok on the gsr with around 10psi and uberdata?

Re:gsr injectors
 

Well, if he doesn't want to wire up a resistor box because it's too "HMT", You'll need the saturated injectors. And yes 440cc's will flow enough for a GSR running 10 LBS. I've read dyno results of 300whp+ where there setup consisted of a set of 450's. Thats cutting it close to maxing the duty cycle, but I'd bring those 440's to about 275ish max to be safe.

its the same price to get 550s so i might do that just to be safe and not max those things out

Re:gsr injectors
 

id say get the 550 jordan, the RC have a disc instead of a pintle like the DSM, makes tuning part throttle and idle much easier i hear :)

Re:gsr injectors
 

750's aren't that much more either I don't think.

Re:gsr injectors
 

Going big now huh? lol. I too would go a little bigger than the 440's if at all possible. I mean, you could acheive your goal with the 440's but just for peace of mind, and the room for more fuel if you ever wanted to crank up the boost ;)

well it was a sad but funny day, he blew the motor, see my post in GD

Re:gsr injectors
 

WTF!? >:(

Stupid fuckers blowing up GSR motors makes me angry...

Re:gsr injectors
 

damn, that was quick... how many psi? and did it go lean or something? ???

the kid doesnt know aynthing about cars and just bought in last friday, he was running stock ingnition timing, fmu with stock injectors, that explains why the motor blew
