hey guys im turbocharging my ser in the next month or so. right now all i got is enough for 370cc bb injectors and either a bb ecu or an SAFC. would the 370cc injectors be sufficient(for now) for the t3/t4 turbo? what is the horsepower limit for the 370cc injectors with race gas? thanks in advance
370cc/min injectors will be sufficient for a t3/t4 turbo, but it depends on goals...if you're looking for 400 hp, then those injectors may not do the job. You may want to tune your fuel map for 4 bar(~57 psi) of pressure instead of the stock 3 bar(~42 psi). You will need a tuned ECU and an FPR for this. The limit for 370cc/min injectors is probably somewhere in the mid 300's. The pulsar injectors are 440cc/min, they are better for more power...I think 50 lb/hr, which is approximately 450cc/min, is sufficient for low 400's hp.
IMO if u are goin for big hp, use the stock 3 bar and 72lb injectors. that setup can take u up to 500hp. that way if u ever decide to make more power u wont have to upgrade the fuel system again.

The 370s will top out under 300whp and that's at 4bar. I'd definitely go bigger if you plan on running more than 12psi. I have a t25 and S3 cams and I was topping out the injectors around 9psi with 3bar psi. And you really don't want to go above 85% duty cycle on the injectors. I'm hitting 90% with around 12psi right now with 4bar and the 370s.
jgycustoms.com he is them for $80 a piece for the 72's and $60 for the 50's. he also has the fuel rails. hes cool just call him up and he will answer any questions
