Ok, I picked up an accel DFI gen 7. I am looking to use it instead of my 8 injector setup. However, I have heard you can use it with the 8 injector setup. Which do you think would be the best way to go about this? I was thinking get some bigger injectors and nix the 8 injector setup. If I did do this what size injectors could I run. I would probably wan tto go pretty big being the car will eventually be a track car. I am currently running 17psi daily. Also any advise on how to hook it up and tune would be apprecieated.

best time so far 14.3 @ 101.1mph

Id use the DFI as the controller for the 8 injector setup, its supposedly got some awesome features/great controll over extra injectors, something about ramping up the injectors /better duty cycles,etc..

No point in using the Gen 7 to control an extra 4 injectors.. that's like buying a half million dollar CNC mill to build billet horse shoes. A complete waste of potential.

Buy some 625cc/min peak&hold injectors from a 1g guy, and a trigger wheel for the Gen 7. Then you'll just have a standalone, and you can ditch all this piggyback crap.

Or sell me the Gen 7 for real cheap.

Well I wish I could sell it to you for real cheap but I think im gona use it. I actually got it for $1015 it is like 4 months old. A guy had it on a race car but is now parting the car out. How much HP are 625cc injectors good up to??

I agree with Dino.. use a single set of suitable injectors..my game plan is to run a trigger wheel and an old school distributor set-up with the Gen 7 in my basement.


boosted 420a and ej2o..(my 2liter v8 eaters)

ill buy your lower intake.

what's a trigger wheel? is it like a flying magnet crank trigger type deal?

probably more than you'll ever make. Someone did the math once, but i can't remember. i seem to rememebr roughly 400wHP being possible.

Those of you with the DFI how long did itr take for you to do the instal?? Just wana know how much time I am looking at.

Actually 625's are good past 400hp and thats what you will need after you ditch the s16g. Good luck.

Wasn't Greg making close to 350 HP with 625cc injectors and a S16g?

How much wiring is involved? Is it complicated because there is no harness or is it pretty straight forward? I am looking at doing the gen 7 as well after I learn more about it. I am sick of the sfmu and safc piggyback. The gen 7 is also capable of pulling timming correct? Off topic but does anyone know when hahn is comming out with their 7 and software?

Anyone have an estimated install time?? Also I am running a T3/T4.

Install time is about 5-6 hours--that's with the HRC 420A wire harnesses, installing the Crane ignition, and swapping in the 625 injectors. This was with two guys working on the install. If you know your way around the engine and ecu wiring, the install time will be shorter. The connections itself isn't hard, it just takes time to route the harnesses through the firewall, placement for the DFI unit, and locating the right wires.

OK, great thanks.
