The HPFP is a 36% increase in fuel capacity over stock, and the Big Bore (BB) HPFP is a 47% increase in fuel capacity over stock. Last night I saw a @nostrumhp Instagram video where they mentioned the BB HPFP will good for over 1000 whp and the Nostrum injectors good for over 900 whp, both on regular pump gas; they mentioned Ethanol blends will be lower. Unfortunately, I do not have the video handy for the precise numbers they stated (nor do I know how they formulated those estimates).
Long winded way of saying: ask AMS for their recommendation based on your goals.
If I had to guess, the regular HPFP should be fine for 600 whp targets, but beyond that you will be looking at the BB HPFP.
Definitely. The Nostrum HPFP will handle stock turbos and/or Ethanol. No need for Big Bore HPFP if you do not intend to go RA600 or higher. I know that the stock HPFP is a bottleneck, even with stock turbo, but Nostrum's HPFP is a huge upgrade over stock.
As I am slowly piling up some parts, I will be doing the HPFP, LPFP, and injectors are the same time -- for this, I am leaning towards going with the big bore HPFP to have it done and out of the way, but I have not purchased either HPFP just yet, and I plan to ask AMS for their recommendation based on my goals once the time comes.
So I been driving my Q around alongside with my old Accord.
I'm starting to notice that every time I step on the gas, I'm getting a .5 or a 1 second delay for me to get a "response" and that burst of acceleration hits me at all at once. It feels like there's not a gradual acceleration.
I recently hit 30K miles with my 2015 Q50 Premium AWD and am looking into changing out the fluids. I would never pay anyone $200+ to unscrew a bolt, drain, and fill. I honestly do not know how a dealership can rationalize charging those kinds of prices for fluid changes (it doesn't take anymore...
I just wanted to kick this thread off and let you know that the development for our Q50/Q60 air-to-water heat exchanger is underway!
With the RS400 in our shop for final catch can testing back in March, we evaluated the VR30DDTT's intercooling system and decided to add our own...
so, long story short...i pulled my 2014 q50 out of the garage to pull my other car in. i left the q50 running so i could pull it back in the driveway and forgot...6.5hrs later (at about 2am) i realize that i forgot to pull the car in...the heater was at 90 degrees, both seat heaters and...
Been poking around the internet on tuning kit for my 2015 Q50s hybrid. Found nothing, so figured I post it here to see if anyone know. I already and exhaust and cold air intake.
Thanks in advance.
