The latest and greatest - like the Flow Force 640, these are unmodified Bosch OEM injectors, flow matched to +/- 1% at idle and wide open, and with all the bits and pieces to make them fit in a Miata. Those bits are top hat fuel rail adapter, bottom hat head adapter, bottom cushions, o-rings, and harness plug and play patches. Dead times are almost identical to the 640cc units. They will go up for sale for $449/kit, but right now I'm looking for one or two folks to join Sonofthehill and Miataman00 as testers. So for you - $400, on the condition that you install them and use them in short order, and share your experience with me. You would also be more than welcome to publicly shame or praise me as you see fit.

 

I would LOVE to tune a car with these, and would be willing to give a discount on e-tuning if anyone is interested
Tuned dozens of FF640's and want to try this new flavor from Nigel

 

 

Interested in the E-Tuning. I don't mind the price for the injectors either! I'll get back to you.

 

Thanks for making these Nigel! My car runs great and I made a 12.3 second 1/4 mile pass with them supplying E85 at 114 MPH. They don't idle quite as smooth as my original Flow Force injectors on gasoline, but still idle 14.7. The idle difference may have more to do with the fact that I gapped my plugs down to .015 again, I need a small gap right now.

I don't think I used more than 70% duty cycle on them yet with E85.

 

Awesome, thanks SOTH!

 

The roughness also might be due to your ms2. Not sure, obviously, but that's definitely a possibility. I'd love to try these on ms3+
I've idled everything up to 1300x on ms3

 

If these are still available, I will take them.

 

You got it. I've got 2 sets for testers

 

I take it back, I must have chatted with my friends neighbor in SF, idling for at least 10 minutes this afternoon. He kept mentioning how nice the car ran, and that it seemed like it was totally stock to him. The idle was solid the entire time, I think I am just finally getting it dialed in.
These injectors idle just fine, I am totally happy with them. I do think my ms2 leaves some to be desired, in many ways. I think the only thing I had working better with the small injectors, was when my cooling fans come on. I really just need to play with it some more, been focused on boosted cells mainly.

 

SOTH, I deeply appreciate your erratic approach to spending money one your car. Roll bar? No way. Totally badass built motor? sure. Ms3? Naw. Top of the line coils? Sure. Suspension? Nope. Fully loaded fuel system? Definitely. Tires? Definitely not.

I wonder what the all seasons quarter mile record is for a Miata.

 

 

Thanks guys!

I honestly don't think too many cars are faster on all seasons. People talk about my car at the track all the time, with the inevitable ending of, "and it's on street tires?" Just wait until next week well, if it doesn't rain anyway.

 

What are these injectors out of?

 

A v6 Renault engine. As far as I can surmise, they use the same valve as the gt500 injectors, just in a slightly different form factor and with higher flow.

 

First set is gone. One more tester set is up for grabs.

 

 

I'm interested in a set, if still available. The first chance I will have to install them and provide some feedback is the first weekend in May, if that works for you.

 

The last tester set is yours if you want them thelarva. Can you send a friends and family paypal to nigel@flowforceinjectors.com and I'll send them in about a week.

 

Awesome! Payment sent, thanks much!
