Spool Helix HPFP overdrive system Spool Performance is really excited to introduce our latest product offering to the N54/early N55 community, the Helix overdrive unit. We have been testing this for almost a year now and here it is finally in a release post. We’ll try to structure this post in a...

PI wins out every time vs. overspinning your HPFP or adding additional HPFPs. It is a no brainer when the stock injectors are ultimately a limit. PI also washes your valves and is less expensive than overspinning in almost all cases.
Injectors are not the limit as they are rated much higher, the fuel pump flow is the limit and hence why Porsche has a six valve pump vs our 4.
It could be adapted but the shear cost of the pump itself will make most cringe and you still would need some kind of adapter to run it.
Marty is right to a point. I’m still not out of stock injectors with the PFS Pod. Rail pressure still is good as well.
ultimately
What is the highest dynojet dyno DI only 100% E85 whp number that is not a vendor or very closely associated with one?
Either way if you want to make real JAM PI is the way to go.

1+ curious what the fastest / most powerful di only car is. Curious if I can beat said car
At the time, I didn't know my actual ethanol content when I was direct injection only, but I am also getting about e60ish nowadays from the pump.
Either way, there is definitely more headroom with port injection and the reflex makes it all worthwhile.
The Di injectors are only limited by the current di pumps and overdrives and with the lack of investment into something better we will never see
what they max out at or if they do.
The reflex Pi is by far the cheapest alternative, but we ran into some issues which I'm trying to work through on my mate's car.
The engine was never designed to run pi and the only true best way is to run it of a standalone.
If you're not aiming for big power I would stick to Di only as that's the cheapest and most reliable option, you can have all the power in the world but you still need traction which these cars dont have in lower gears due to IRS.
