"Our engine runs timing in the single digits Beau "
Hehe, yeah don't I know it. In some areas its close to 0, hehe. But thats the way it is with direct injection, the way the charge stratisfies, the flame front is very quick, there is no need to try and propagate it too soon. But, towards redline we would be approaching 15 degrees of timing or so easy.
BTF, about the delibrate speeding ticket comment, beautiful. I would suggest tuning to get rid of the knock if you want to sell it as a kit, but keep your current tune, and just get a better intercooler...
I don't think I can run over 18 psi, this is an NA-T motor with a TT headgasket, so I might be around 8.8-9.0:1 or therebouts.
Oh thick gasket = poor quench. Thats the reason for the low boost.
Dude IM serious me and the wife both got tickets last year cause the thing was soo quiet and with the small turbo you could dial up 20mph in 5th unnoticed if you had the radio too loud.
Now it takes a little more throttle angle in 5th to get pressure, and thats fine by me. Beleive me the motor is no slouch off boost.
Id say 4200ish about the 355kpa. I have the profec just stuck between the seat and console so I'm just guessing. It flashes the highest boost for a few sec after you letoff, when I saw the dash flatline I looked down and it was already past 320kpa.
Better data is coming soon I finnaly got that awful Sentra running. It seems it doesnt ike the modified Maf signal from the E-manage U.
As far any kit type stuff, Id wager I'll just provide the hardware and post up the .hpt that works for ME. Anyone looking to push this boost (more than 21psi) should take it to a dynoshop or at least have the hardware/software for some good track tuning to make sure your not getting KR with what you have on YOUR ride. start low and creep up a few psi each pass.
That being said when on "low" boost the only thing I had different from stock is a lightly modified MAF table for the 3" pipe it's in. all else bone stock and old gas. It got the same KR it has from the day we brought it home, light cruise and if you lug it in 5th.
I dunno man, it always happens around 70-110kpa. It's like they are delaying the PE and it preignition instead of detonation. But it always seems around 2-3deg.
I don't see turbo timers used much by serious turbo guys. New turbos are water cooled, and with synthetic oil, there's not much need. Just don't shut the car off 2 seconds after a long 20psi run.
Just as a thought. Are you going to use a turbo timer n this new beast? Id hate to see a new set up broken by after run heat.
No need Bro. Turbo timers are compeltely unnessicary on a Watercooled turbo. On a journal bearing oil cooled turbo they can be of use simply becuase there are no other means to cool it.
But the waterjackets siphons away heat long after its been shut off.

So if I am reading the map correctly @ 4200 RPM you are making some serious HP. And when I mean serious, my conservative calcs are in the mid 3s whp.
Am I way off here????
How much throttle angle before the smiles begin?
When you get that thing strapped to a dyno, you should make a NA run, just to see how the 2.0 does against the 2.4.

Im shooting for perhaps this weekend. As soon as I button up that god awful sentra.
besides I cant wait to hook my databoard up to it. Im dying to see turbine pressure,backpressure in the exhaust and pressure drop across the IC (dude it's not really that much from Bst controler to dash but after 20psi I have no clue.)
I think were going to 400whp on high boost. The top end pull it way to killer for it not to be. and Im seeing 51% duty cycle....
I get peculiar behavior. sometimes it feel super responsive off the bottom. Sometimes it feels like I have a loose charge pipe clamp.
When you look at the actual vs cmd Tps and it's pretty obvious why. Somtimes Im asking for 35% and get 60. somtimes Im asking for 60 and get 35%. Same goofyness Dave is getting with his 16g. annoying at worst. when it's cracked by hpt we'll jsut peg the whole map at 100% availible like we do everythign else.lol
