Anyone come across these?
Seem well priced for the flow. I havent checked the impedence yet. I would want them reconditioned and dead times measured first do The1 would be the man for that! Look like a good cheap upgrade for my mates car.

Ive already set the reg to 45 psi (fixed) would going higher affect the opening times?
Car has upgraded lines Walbro intank pump and adjustable reg with standard rails.

like you say assuming they are the right impedence then they should be right.... I'd say they will be.

mates car is only a 4cyl? Yes pressure will change deadtimes a bit and usually flow rate to. All depends on the injector design

chuck a set of 36lb ones in, there $199 flow matched. Could turn them down to 43psi which would drop them to 32lb or so. Or just run at 51psi if it's a MAF model you can play with the EOI delay to get some nice mix higher up.

Thanks mate, you're saying you could sell me a set of 8 36lp for $200?
It's running 12P with BPC of .13 peak VE is at 95%

They are rated at 51psi is that what pressure the super 6 ran at?

yes they run 51psi or 3.5bar from factory. Yep flow matched sets on my ebay. though there sets of 6, i could do a set of 8 for a little more if your keen.
