Sound Performance Fuel Injectors

[crazysupra2JZ]

has anybody used the SP 780cc injectors. They're $55 each. it's cheaper than getting RC 550cc

SP 780cc Injectors


Theses fuel injectors are flow checked, individually scribed, hand selected and then carefully matched to within 1% of each other for optimum performance in your vehicle. All horsepower ratings are calculated at 90% duty cycle at 43.5 psi upon a BFSC of .50. Compatible with all known aftermarket drivers.

i figured getting slightly bigger would be better so i don't run the 550's too much

What kind of power goals are you shoot for? If it's a little more than 500 HP (but no more than 575) I'd go with the 6xx cc injectors as they will not be as hard to tune as the 780's .

would these injectors be overkill if you pushing a tru T4? i am loving the price could you post a link for them?

bingo. no point in GROSSLY oversizing inj....unless you're running standalone.

heh. yet again, a "tru T4" can be anything from puny to HUGE.....that's like saying you drive a car. yes, what WHAT kind of car? WHAT T4 are you going to be running?

 

[starscream5000]

The injector will pump out as much fuel for the HP they are rated for. A good rule of thumb is 1cc per 1HP of fuel with like 20% fuel flow capability left in the injector .

Exactly what I was thinking, but I thought I'd be polite and just answer the question .

i am aiming at the jt61

 

[starscream5000]

That's nice, but what are your HP goals? Find out what your max HP is that you want, and then go from there with choosing the right sized injector .

here's the link to all the injectors SP offers

http://www.spracingonline.com/default.asp?action=product&vehicle_id=2&category_id=66

i am shooting for about 600 rwhp... i just don't want to keep the 550's running at high duty the whole time. i do know that getting too big injectors isn't good either as they will not give a good flow of fuel at lower rpm's when i'm not demanding power.
so you guys think somewhere in the 600's is good for roughly 600 hp?

 

[starscream5000]

The 680cc should be fine .

yup, something over 600cc should be fine for 600rwhp.
