That's exactly what I needed.... thanks! So it's intermittent. I can hear it sometimes and not others..... I'm thinking about replacing the pump with a gt500 pump. Not sure yet....
I have never been able to hear mine at all. Only way I know it works is because iat2 levels are fine and when heatsoaked after parking, they drop like a rock when I start the car.

Thanks! It actually made 779 but they only did one conservative pull, up in the mountains. Back at sea level now should make more. Whipple Gen 5/132TB/3.625 pulley/E85/Long tubes/OPGS/1050X/Fore Dual Pump kit/Lund tuned.
Man, that is nasty! Car must run so good.
Must pull like a train!

With this A10/3.15 gear it’s crazy. Traction control was lighting up on gear changes at or near triple digits (with Michelin Pilot 4S’)!

Just ordered a VMP tune for my 2015 w/ Phase 2 kit! Already has boost-a-pump, X pipe and Roush catback. It's a manual with 19" SVE 350s and Indy Firehawk 325s on the rear. I'm hoping after VMP is done that I'll have at least 625 whp, ideally closer to 650. Original owner's dyno sheet with install showed 580 which seems wicked low for P2, but know things can vary dyno to dyno so didn't think much of it.

Original plan was to replace the fuel injectors but my less exciting daily driver seized on the freeway last week and is likely FUBAR'ed and out of warranty, so not willing to drop another grand on injectors at the moment given that fiasco. =(

From what I can tell I'll be still unable to hit high 10s on perfect launches without injectors since I'm not an A10, but after putting in some seat time this summer I'll be giving it my best effort around August! Maybe with slicks though...?

So wanted to pick the brains of the guys running the p2 for a bit now. Here is my dilemma. There's a 20 gt non pp prem available at a local dealership. Priced very well especially with the 0% offers they have going. After a Roush p2 added to it I would in theory be out the door with a lower payment than my current 18 gt prem pp1. Current car is pushing 516whp/454wtq running e85 with lth, flex tune etc and support suspension/ other mods. It has been a working mod proj but dd for its life. Primary 3yr warranty is up in a couple months. Would the 3.15 in the non pp car on the p2 tune with 91 feel a little sluggish out of the gate in comparison? Here in AZ not only do we have heat but best standard pump is 91. We have e54 flex fuel in some areas with real e85 at only a couple places. If I went with the new car, I'd stay warranty friendly mods during the build at least at first. So all factors considered, and with all of your experience with the p2 (who knows when the new cal they are coming out with will be available) what path is more appealing? Keep modding existing, or start from scratch with the boosted option? Running 10s full weight would be appealing, especially with full warranty period available.

I've been squeezing the hose to test.... but without the car running and the key in the on position, I can normally hear it. When it's not working, I can't hear it...
Mine never runs unless the engine is running. With my temp sensor in the HE, mine only runs when the engine is running unless the PCM senses too much heat. I have NEVER heard it run without the engine running and then there is too much noise to hear it.
