380cc inj good for 400whp
Is it possible to tune the T-NETICS kit with the UTEC to 400 whp using the 380cc injectors? My car is currently at GT Motorsports getting the UTEC and map sensor installed and tuned so I was wondering what to expect the final numbers to be. Do any of you have any ideas.
Thanks

ya cutting it kind close but running the fuel pressure around 55 should be ok. minimum 42lbhr injector for 450hp (crank) at 43psi fuel pressure is what the injector calc. comes out at.

Well I am doing a basic fuel return, just like the APS fuel return. I also am also staying with the stock 380cc injectors unless I am told that they are maxed out at the power level I want. Like I said D350Z10 on here took the stock 380cc injectors to 450 RWHP before they were maxed out. I am shooting for low 400 - 420 RWHP. I guess anything over 400 RWHP that can be made safe. If you want to be 100% safe or want extra room to go even higher later then the 440cc would be fine.

The denso core 380cc injectors are good for 400whp. Anyone that says otherwise is just tying to sell you something.
I personally don't see the point in going with the 440cc injectors unless you're planning on breaking 420whp without planning on ever building your motor.

Here is an interesting page to do some calculations:

Anyone who tells him otherwise is walking the line...

There are various ways to make power....with differing levels of safety. Oftentimes, there is more than one answer to a question, and then the customer has to decide based on their comfort level.
We sell all the RC injectors here, if you need anything: http://www.forgedinternals.com/store/home.php?cat=251
We also strongly recommend a return fuel system as well, as its the only way to get stable differential fuel pressure at the injector nozzle.
