I will probably have a 2.5 DP and have a full 3" exhaust. Stock d16y7 w/vtec, activating at 4400 rpm?

 

how is anyone suposed to know the answer to this question?
not being mean, but your question is pretty open, it has allot of variables. But its a small turbo so, fairly low i would guess......~2500?

if your asking this then please tell me why you are buying a turbo?? do a little more reading and maybe you might be able to answer the question yourself

im not trying to flame you but man you need to study up on some things brotha.

That estimates definetly way too low. I've got exactly that Turbo on my B18b1 with a full 3" exhaust, and I don't reach 8psi until about 3500rpm

I'm going to say that you'd probably spool up to 10psi on a D16 at around 4000rpm, but that too is a very rough estimate, and it's more then anything going to depend on you're overall setup

 

I have seen flow charts and I have studied. I want personal expierences.

 

i have the same turbo on my car with 2.5" turbo back exhaust and vtec at 5200rpm. i hit 8-9psi by about 4000rpm. i've ran 12 for a lil bit and it seemed to spool just as quick.

 

my saab turbo on my hf manifold dont reach full boost till like 3500 or some ****..i mightt have tiny *** exhaust leaks, but thats about it..reall tiny i think maybe its the small *** runners or whatever on the manifold..those cant flow much i'd imagine...soo small....

 

my friend has a clipped .42/48ar he is at full boost around 3000 on D15b7
