Fuel injectors for EFI engines

[John Broughan]

I have been told that Magnas have massive flow fuel injectors. I put a query on the TOYMODS forum, and got this reply.

I had a look at the injector specs and the 6G74 (3.5L V6) injectors were about 600cc/min. But my surprise was VR4 injectors! They are 900cc/min! Get some of them, or EVO ones they are about the same as VR4. But they still wont be a bolt in fit.

900cc/min is massive. About the same size as the supercars run.

I asked by FI guru, Choco and this was his response.
They are pretty big injectors. I suspect they are peak and hold (P&H) injectors. At 900 cc/min (divide that by 10.5 for lbs/hr, which is about 85lbs/hr) these injectors will look after a 500HP V8. Refer to my articles in ASR for the formula and ratings.

actually those injectors will look after a 1400hp V8

900cc injectors are huge!

Gonna have to check these out, what is the part number of these injectors?

[John Broughan]

I don't know about the part numbers, i am not even sure if the above is actually true. Trying to finds definitive info about ths sort of stuff is very difficult. I ended up using Toyota injectors from a larger engine.

If you can get me a bosch part number I can tell you what it's capable of, I've got an entire bosch injector listing here somewhere. Perks of being a journo
