Has anyone who is supercharged gone with larger injectors from the 410cc?
What size did you jump to?
Did you modify anything other then the injectors when you did (fuel rail etc)?
What kind of gains did you make after a re-tune?
Before or After the injector swap did you change your pulley too? 65mm or 55mm?

Thank you!

did that BEFORE I posted, thanks

doesnt matter how big you up injectors if u dont up the boost also. your not going to make any power just ____ away more gas...

m6ar2cel6oTC

Well if you searched you would have gotten at least a few post of mines cause i used to be s/c and had bigger injectors. Like Pete said if you not gonna raise the boost you don't need to.

guys stop bashing the guy.... bigger injectors wont give you more power....they will only allow you to make more power..


let me break it down... 410cc injectors are good for like 230hp~ with a 13 afr at redline... i personally dont like 13 afr for boost


if u want safety and above 230 hp i would reccomend a 440 cc injector or a 550cc but upgrading injectors also means u need to tune for them so a piggy back is a must

Thank you, that's the kind of info I'm looking for. I'm going to the dyno next weekend (to see what #'s the S/C is putting down), after that I'm putting in my eManage blue and hoping to squeeze more HP over the crap TRD flash. After that is the eventual 65mm S/C pulley upgrade at which point I figured I would be pushing the max 410cc injectors and was wondering how big to go after that etc.

^^^ lol at tuning with the emanage blue. That's one of the worse emu to tune with. Save your money for a tune and sell that emanate blue and buy at least a fic.

Going bigger on the injectors with the stock supercharger would be beneficial if you plan on racing your tC to insure that you are not using the fuel injectors at full duty cycle.

SoccerBoy_AP

If not Blue then Ultimate?
Or just not at all and go FIC?

Slow_2az

either the ultimate or the aem FIC, if u want to be able to add timing i would go ULTIMATE

but personally i would go with the FIC and tune for a 12.0 afr with the new pulley and some 440cc injectors or 550 i would probably go with 550 cc because u know u will have plenty of fuel..... and they are the same price

AEM FIC is a good alternative to Emanage Blue. I ran my previous turbo setup with an Emanage Blue and had no problems or issues. When I do my next turbo setup, I will elect for something else however, something like the FIC. I have heard some really good things about it. The Ultimate is a better comparison with the FIC as far as capabilities, but you'll spend more money on the Ultimate alone than you will with both the FIC and a harness.

bcnu_702

You can also control timing with the FIC from what I understand. The Ultimate and FIC are very comparable with respect to capabilities.

SoccerBoy_AP

Good point!

I'm not trying to go nuts with the supercharger. When I took the stock car and had it dyno'd it came in at ~140whp. I decided after that my goal would be double stock hp, ~280whp. Financially not looking to have to drop the $ to play parts swapping in the engine (yet), seeing as that needs to be done once you pass ~300hp.

I'm just investigating all the things I don't know, since my s/c warranty is gone in 6k miles, I figured bigger injectors would be needed to push 280whp.

Trying to get all the ideas together and have a game plan instead of going into this blind. Not as much of a car guy as I wish I could be...that's why I come here!

Slow_2az

if you read thoroughly i said the ultimate can advance timing.... both units can retard timing...but fic cannot advance it

soccerboy I was looking to do the same thing, just add another 30-40 hp to get it near estimated 260 range. Ill be looking to go back to a oem ecu, tune with a AEM FIC, and also add a 12lb pulley. Right now I have 9.5lb NST pulley, intake, header, HKS exhaust, TRD tune, and hks bov.

m6ar2cel6oTC

Put a 14psi pulley. If you ho 12 most likely you won't kit 12psi.

SoccerBoy_AP

Actually I was looking to jump to the 55mm pulley after I get.... a front mount IC...
Yes I know I know I know... loss of boost .. I know

That's why I want to jump to the 12psi, then after the IC I'll have around 10psi... a cool 10psi which is more stable then al/meth injection from a tank that can run out!!!

But before all that I'd need the injectors, which I will probably do the 550cc's just for expansion plans.

bcnu_702

That is true.

SciMeiji

Yes, for any boost higher 9.5lbs you'll need an IC. I think that should be the first thing u do then get the tune and pulley. The biggest area of power loss with our SCs is the blazing hot temperature of the boost were feeding our engines. On an 80 degree day the 9.5 pulley is producing boost temperatures close to 200 degrees!

Make sure u post some pics of ur IC when u do. It suprises me that more SC owners havent fabricated an IC for there car. Good luck.
