    Bosch EV1 775 vs EV14:







    Length is identical both 'long' injectors, both 14mm top feed, I did have to swap the o-rings off the 775 onto the EV14s though, the old o-rings had a larger outside diameter than the new ones for some reason.

    Car starts quicker, idles much smoother and is more responsive at low and part throttle situations.
    Did you adjust the tune to suit or just straight swap? How much extra head room do they have over the factory units?

    Straight swap

    Car has Wolf V550 EMS and a tune to suit the old Bosch 775 bluetops which are also 24LB injectors.

    I believe the car may be cammed, I think it was sitting on 11" vacuum at idle and put out 156KW/wheels.

    I should probably get it run up on the dyno again to make sure to be safe but it drives and idles nicely.

    I'm planning some further work around January, I'll need the tune redone anyway as it's going to get a VT dizzy installed and my 8x LQ9 ignition coils installed, sequential injection and ignition.

    They can check AFR for me then to make sure it's all good.

    Very nice, how'd you solve the locking clip issue posted earlier on ? Or is this your second set of injectors?
    Sorry for all the questions but I'm about to boost my 304 and also need injectors.

    Second set of injectors - I bought a set of 19LB ones first and went to install, come across the issue of the locking clip and then put the 775s back in.

    I thought about it, then got a set of 24LB ones and just put them in without bothering with the locking clips, they're stuck in the rail bloody tight with just the o-rings holding them in top and bottom - you'll see what I mean when you try remove the injectors from the fuel rail, you've got to yank on the ****ers and twist them around heaps before they finally pop out.

    With the seals holding the injectors and the bolts securing the fuel rail to the intake manifold - they're not going anywhere, lifting or moving.

    I'm going to upgrade to these ones when I'm boosted:

    https://www.bosch-motorsport-shop.co...-injector~4308

    By those I mean I'm going to buy the same injector below but for half the price:

    https://www.summitracing.com/int/par...lu47/overview/

    Its a Ford Performance branded Bosch injector - 0 280 158 279 is its Bosch part number, its just rebranded as Ford Performance:

    You can buy from from Bosch for $830+ shipping or $400+ shipping for the 'Ford Performance' ones.

    It will be the same deal with the injector locking clips but it looks to be OK - most the other cars I've worked on don't have injector retaining clips, they just hold in with the fuel rail bolted to the intake manifold.

    Fair call. Got a link for where you got the latest ones from?
    And why not put the boosted ones in now? If your going centrifugal blower whatever you choose needs to be tunable for off boost /idle anyway?

    I've edited my post above with a link for what I'm going to use when I'm boosted, 550cc/50LB (Ford rates it as 47LB because they measure at different fuel pressure than Bosch)

    I'm not sure what power you're targeting but they're supplied by Ford for 2011-2014 5L V8 Mustang supercharger kits rated at 525hp so they're going to be fine for me (I'm only targeting 250-300KW/wheels)

    This is the link to the 24LB ones I bought and have currently installed:

    https://www.injectorplanet.com/produ...sch-0280158089

    The only reason I didn't buy and put the bigger ones in now is I didn't want to have the car undriveable with 2x larger injectors than what it's tuned for in the interim, saves me having to get the car retuned at the moment and these were approx half the price just in case they didn't work for what ever reason - they're just a test of the theory that if the EV14 injectors can be used in our cars and with their better atomisation of fuel make for a smoother running engine.

    Mind you I think with ordering the incorrect injectors first up and then buying the 24LB ones I paid about the same as just buying the 550cc ones I'm going to use anyway lol.

    Thanks mate, I'm aiming for the same power as yourself. I'm curious why you didn't get the larger items straight away though?

    You'll also need some adaptors, EV14 injectors have USCAR connector instead of ye olde Bosch Jetronic like our EV1 cars, I have a set of 8x these:

    Work a treat!

    May be available cheaper out of Summit Racing

    Great, thanks mate! What kind of boost do you plan on pushing?

    I'm only planning 10-12 PSI with a cam to suit boost, I'm hoping that will get me into the ball park of 250-300KW/wheels without making banana rods of the stock short - one of the reasons why I changed from PD to centrifugal was that because a PD blower will give you 100% boost at 1500 RPM, rather than the centrifugal which will give it at your maximum engine RPM (say 5500RPM for us stock guys), PD makes for a much nicer street car with balls under the curve but I'm not sure how a standard 304 is going to like 10-12 PSI at 1500 RPM from the Eaton M122 I had vs 10-12 PSI at 5500 RPM with a centrifugal charger, its a lot of cylinder pressure at low RPM in the Eaton M122.

    That and its easy to remove if you get busted by the police and defected, few bolts to remove it, put the airbox back in, flash the tune across to the NA one and its back to a stock 304 for road worthy purposes lol.

    When the stock short starts blowing blue smoke and gets a bit tired I'll probably get a short built, 355 or 383 with some forged rods and a forged piston with a meaty skirt to handle more boost.

    I'll be very interested to see how you go, I'm doing a very similar set up. 12psi, 276 cam, t700, water injection etc etc.

    I'll most likely use Camtech CT248 532 - first on this list.

    https://camtechcams.com.au/camshaft-...ion%5B4%5D=125

    I'll be using WMI on my setup too, I can't be ****ed trying to fit in a front mount cooler, I have a programmable Devils Own WMI kit in one of my other cars, we couldn't tune the car properly but we had it running 23 PSI with a hybrid turbo and big FMIC, even with the big front mount, with an undersized nozzle the water/methanol injection picked up 7KW at the front wheels alone from it injecting, its diesel though so the principle is different on its use for a diesel car but it works well for controlling air intake temps on any boosted car:

    http://www.alcohol-injection.com/en/...-stage-2a.html

    Thats the kit I have in my other car.

    What I'll do is I won't have the tune adjusted for it, that way worse case scenario if it fails we just lose power and have hot intake air when beating on the car, otherwise if its tuned specifically for the WMI being there and it fails it will probably cost an engine.

    How's that cam differ from the 276?
