Would you say that the volume of air produced at 6 psi from a t3 with a .60 ar on the compressor side is equivalent to that of a JRSC at 6 psi on an h22a1? How bout at 9 or 10 psi?

i would think the t3 would have more since its more efficient than a roots style blower...but im not positive

Well, in the end, 6psi is 6psi. The difference that you're speaking is is how it's generated. All depends on what you want..

I'm just wondering cuz 6 psi is not necessarily 6psi. It's all about the volume of air and I'm wondering more in terms of that cuz if I were to compare 6 psi from a t3 and 6 psi from a t3/to4e or further off, 6psi from a t4, the other two would produce more power than a straight t3...or at least I think!! hahahaha

Hrm.. That's interesting... I'll be watching to see who has more information.

very true, its all in CFM... I dont think many of us know how much JRSC can produce... Plus you have to take intercooling into consideration, since the charge air would be less dense.

well, the reason that I'm wondering is cuz I'm using this t3 from a merkur on my h22a with a jrsc fmu and I just want some other opinions if this will be enough fuel for my h22a1 with stock injectors and an inline.

I think you should just sell me that turbo, and find something bigger ;)

Nah, you should be ok with that turbo, its one of the biggest factory t3's

Oh, that was your question? The FMU? I have the JRSC FMU.. It's adjustable. At least.. yours should be. There is a nut on top, that you use with an allen key to adjust the ratio.

At least all of the ones that I have seen work like that. Maybe it's al old model if it's not adjustable?

Here's a pic of mine..

I'm pretty sure that they are all the same fmu's but from what I understand, the only thing that is adjustable is the idle fuel pressure and not the rise rate, so it will stay at a constant 5:1 rise rate. I'm pretty sure that I should be alright for fuel running my stock lude injectors (310 from what I read) as well as my inline. But if it were a t4 compressor then I think there's more air than the t3 so I'd need more fuel...does this make sense to anyone else?? hahahaha
