i wanna upgrade my vortech s/c, right now i have stocks so want to upgrade to RC 750cc injectors, so will work out with my SS box? i heard that has scaling problems, so anyone can let me know if does? thanks

 

upgrade to your power goals, but I was told it can control bigger injectors. 750cc is huge, you may wanna go standalone if your going crazy power

 

yeah? because i search about this topic but i can't find the answers, as my cousin is selling me his 750cc RC injectors and clips brand new for only USD$250 dollars, so wanna be sure of it.

 

NO---the SS box can not scale injectors that large . Some say they have done 440's . I sent my ECU in to Technosquare and had them flash it for 550's only . Then use the SS box to tune for the Vortech SC

 

wow that is bad news for me then...... so i must have the turboxs? right? or send my ecu to re=flash to 750 cc right? mm hey what you guys recommend me?

 

750cc injectors are over kill on a vortech I have 600cc And there not even close to being maxed out. I only hit the 50% column. I know SC take more fuel but they only need so much. The larger you go the more problems you will have unless you go with a standalone. Just my opinion..

 

thansk frankie ! for your advice, so i should go with 550cc something like that? so with 550cc can i scale with ssbox? or have to buy the utec?

 

Or you could get Osiris Tuner. Shipping next week.

 

I'm not to clear how the ss box works. I was procharged at one time and used the 255 walbro in the tank and utec to scale injectors.. I ditched the FMU that came with the kit there junk. How much power do you want to get out of your vortech? And it's still early let wait for some more Vortech guys to chime in. Listen to Sentry and Bogger they know there sh*t.

 

thanks for your advice i think i'll keep on my stock ones

 

how much is dat?

 

You can always go with some 380cc that come with the TN kit you can find them used on here all the time. It also depends on how much hp you want. When I had my procharger I maxed out my stock injectors, 98 percent duty cycle at 5200 rpms, I was using a Utec for ems.

 

hey thanks for you advice, the problem is does 380cc can be scale using my ss box? or in a word what is the maximum injector that can scale using the ss box? thanks again

 

We run 440cc injectors with the SS box all the time. You can run 550cc too.You can run 720cc with the SS box but you wil get cold/warm hard starts and that sort of thing.

 

I am interested, can you pm me some more info

 

IMO I would purchase a UTEC and drop the SS box. 750cc are a overkill, but you will never run out of fuel. Depending on what power you want to make in the long run with the S/C, keep the 750cc or buy at least 600cc like Frankie945 said. What other upgrades do you have?

 

thanks for you advice, so i can run with ss box using 550cc injectors, so thansk a lot man hehehe because i want more power now in my Z thanks hey any of you guys has any base map for 550cc for ss box? thanks

 

thanks, right now i have only the vortech s/c full kit using 3.12 pulley , ATC 6 spring clutch , lightweight flywheel, so that's why i want to upgrade the injector to get more power with a good tune

 

The SS box is a pretty simple piggyback , but from my understanding of it . It cant fully control fuel and timing unless you are at WOT . I dont know crap , but I tried and tried to scale the 550's with not much luck . The cars ECU always wants to re-adjust the fuel trims to compensate for the changes I made . Maybe there is a way around that....dont know .

Good luck with it !

 

thanks a lot man, i think i might go with 440cc injector as i saw lots of threads that people have no problem to scale with ss box. thanks a lot man
