IMO around 300 Ish with proper injector Duty. It's forced induction so they like a bit richer, my DSM cars would be approx 300 to the crank with 550's max should be very similar. Here you can see what different flows can support, approx.

interesting, so when you do move to a BVH, and you want 80% duty cycle you do want the 550's

Any time a BVH is installed its recommended that you run larger injectors. The big cam and valves is when you need 550+ simply because of how lean your making the car. Only reason I tried to persuade user against is because there is no mention of that here or in future plans. Why spend the extra money/time for something you can't max out. If your doing a BVH you have to pull injectors anyway.....so put in the 550 then....

Considering the Bosch injectors are the identical ones used on the Shelby GT500, and some of those motors are putting out 750 HP on stock injectors, I'd say the injectors are good for close to a 100 HP per.

Maybe fulley maxed in duty cycle but......generally not going to happen. You can't take injector rates for a high CI /VE car and divvy them up into eighths then expect it to come out the same

Plus as I ststed previously Forced Induction like to see 10-15% more duty cycle compared to NA engines.

Both mini and mustang are SC ....one is just massive CI comparatively

I'm pretty sure if the OP goes with 550 he will have room for whatever I just find it pointless unless BVH is present.
I'm at 85% on 2150s on my EVO because of planning not guessing how much room I'll need. Duty cycle and corresponding percentage amounts are far more important than people give them credit for

Agreed. And I know zero about Mustangs so sorry about my post.

Fin,
It just so happens that the mustang he named is one of the few limited edition ones with a supercharger...most do not have this so it's not entirely common knowledge. Plus you get good cars where you live....no need to mess with Mustangs when R33s and EVO V/ IVs floating around

Also recently added the AEM Methanol kit.



I installed the pump under the passenger seat and the tank right behind the passenger seat because I wanted the weight center of the vehicle. Plus I don't have a back seat.

Nozzle is driver side horn.
