I allready have 550/720 setup and a walbro 255lph, RTEK 1.7 and a SAFC-II.

Can i boost like 12 psi with this setup and the complete GREDDY TD06-20G kit?
Bigger injectors??
FMIC??

How much HP can the 550/720 combo support?

I WON'T BUY A EMS YET!!! but can i get like 300 reliable HP untill i do?

 

mmmmmm Don't quote me on that, but 300 is maybe a little too much for 550/720 combo. I read somewhere that your fuel setup would be good to something around 250-270 RWHP. So it depends on the fact of wanting 300BHP or 300RWHP.

I'd rather go with 1000CC's, so you're gonna feel safe, the % duty cycle won't be maxed out, and you'll still have plenty of fuel of you wanna tweak the boost later.

12 PSI on TMIC is pretty much the limit, unless you start spraying water on it or something like that. For every project of over 10 PSI, a fmic is almost a must and you can buy a used old school HKS or greddy kit for maybe what, 500$, which isn't really expensive when you think of the price of a rebuild.

you do not need a rebuild if you boost over 12psi on the tmic
330+rwhp have been managed with just 550 in the past

 

550/720 is only good for about 275whp @ 85% duty cycle, assuming 40psi base, with a 10psi rise
720/720 300 @ similar settings
550/1000 335
550/1600 440

 

doesnt the kit come with an e-manage? most of the turbo kits do.

 

no...this kit was used!
FMIC and 4+720cc it will be then!
