2404ever · 12-29-2008, 09:38 PM

does any body know what inj size on the vq37VHR engine (yellow) color.

3,696 CC... in all.. so to find size per injector.. divide by 6...

3696/ 6 = 616 each .

i got new ones. 4000 cc. wide range . meaning when i boost. i can move them to be bigger.. but all motor...

-full racing headers
- stillin gen 3 intake system
- stage 3 intercooler to keep the car running between 150- 170 dagree.
- test chip (35hp)
- type S ams tune
- 3 3/4 inch exhaust pipes.

thats about half of all motor

dyno proof
wheel hp : 396.889
torque : 362.1

give or take 4 hp & 6 torque . . 3 dyno runs.

Uh...i'm pretty sure ^this guy has no idea what he's talking about

Engine displacement does not equal injector size. there is no way each stock injector is over 600cc. People that go twin turbo upgrade to 600cc for > 500HP.

Stock injectors are 380cc at most.

100 whp and 100wtq from bolt ons? NA? No way!

Full of BS, they dont even make 4000cc injectors.

Post pics of your motor and dyno slips

soaka1 is smoking some of grandmas premium stuff.

Bring your 370Z with "396" RWHP to Texas and I'll show you what boost is. LOL

I agree. And your right about the injectors. I don't know what size the stock injectors are on the 370Z but I do know the 300ZXTT runs 370cc stock injectors. So it's gotta be close to that.

Hey guys, I need your opinion on injector uprgrades... I'm planning to raise my rpm rev limit to 8000 rpm and some dude at my local track keeps telling me that I have to get a larger cc fuel injector for the job. I have already installed better pistons, crankshaft, con rods, new valves and springs, but I don't know about fuel injectors... I'm not very knowledgeable in fuel systems, but I know that larger injectors are normally needed for forced induction and high horsepower applications where more fuel in needed at a given time. Someone told me you could divide the cc of the fuel injector by 5 and multiply that number by the number of injectors to show how much horsepower it can handle, but what do I know. If I get the injectors, I'm only planning to go around 440 cc for injectors from GTM and I might get fuel rails, but I don't think it's necessary. In theory, shouldn't 370 cc injectors handle like 450 hp and I'm not doing forced induction or anything like that. I just want to know if this enlarging fuel injector is necessary for raising the rev limit....Thanks

P.S.: Feel free to laugh at the stupid things I've written through my tiny knowledge of fuel injectors. There probably is something that I've written that sounds completely wrong, but hey I don't know much...
