HTA 3586 don't really KICK until hit +28psi??
Simply CFM vs boost modified by displacement. The same mass of air goes in the motor whether its 23psi or 29psi, but the amount that backs up in the manifold is different. I have 2.0L that makes 590whp with the 3586 on pump as well but they are running the aforementioned 29psi.
Quick math (assumes VE stays constant)-
2.4L / 2.0L = 20% displacement difference
29psi x 80% = 23.2psi for the same power
I had changed cams and headwork between the 2 examples so the engine was able to make a little better power per psi than previously. Rough math and not meant to be scientific, but its close enough as a rule of thumb.

You get it.

very good on low boost, I made about the same power on my HTA3586 at 26psi as I did with 40psi on the black.. and yes like was already mentioned you're ahead of the game for lower boost power with all the VE mods and increased displacement

Just talked to FP regarding HTA3586 and they said
1- It will shine 30psi on racegas
2- It still need at least 24-26psi on pumpgas
3- It need more air really perform and wont ran good at 17-18psi

At 18psi on a 2.0L the 3586 made 390whp which means it REALLY picks up in the next 5psi (making 500whp at 23).
On a 2.4 the 3586 made 482whp at 18.1psi and 496whp at 19psi. Again it really picked up in the next 5psi since it made 588whp at 23psi, 625whp at 25psi, and 648whp at 29psi all on 92 octane (not even 93 like you have).
Switch to E85 and the 3586 is even cooler still because you can run some timing at low boost.

So did you not see the dyno graphs I posted? Of course it makes better power at higher boos,t that is a given, but it can still make 500whp at 23psi on a 2.0L running pumpgas. There is no stock appearing ANYTHING that can do that so I still am saying the 3586 doesnt need high boost to be cool.

I'm not talking about Dyno numbers.. I'm talking about spooling and boost response
Appreciate your help
With a lower boost target it comes on faster. The more boost you want the longer you wait before it appears. My car hits 21psi at 4200 on the 2.4, I'll have to doublecheck the 2.0L but I think it was on by 4600.
