The definitive spoolup thread
#42
y8s need to run more boost like yesterday! That turbo is looking HOT. I just bought a Borg Warner S256 that I got an outstanding deal on. I did not pay anywhere near the $1300 MSRP, and yes it is brand new. It is supposed to be equivalent to a GT3076R with the same spool characteristics, but without the ball bearings (It is rebuildable in other words.)
But alas I am getting the topic.....off topic.
Everyone needs to run more boost, NOW!!!!

When I wired mine up, I ran new wires into the cabin instead of grabbing stock wires by cutting them at the diag box and moving them at the ecu. I wanted my wiring to be "cleaner" than what the FM manual instructed me to do.
I did grab +12v for the boost solenoid from the appropriate pin at the diag box, but I opened up the box and made the connection inside it, then closed the box back up. So it all looks factory, or psuedo-factory at least.

Theres no polarity on the boost solenoid is there?

i'm teasing. but wtf is with that bottom scale? can't you make it 0 1000 2000 3000 4000 5000 6000 7000 or does it have to be all wack like that?
fix that and i'll let you keep the "i'm cool like matt" statement.

not with my 2.5" > 2.75" > 2.5" > 2.25" > (2) 2" exhaust....
5th gear pull was a 4th to 5th shift...just showing how the EBC is working for me. I see full boost at 3800-4200 depending on gear/load

T25/28 on a ported and polished 1.6L with a megan manifold/dp and cherry bomb exhaust. WG starts opening up at 6.4 psi and 3471 rpm to keep from overshooting the 13.5 boost target. Would probably be much better spool if I didn't worry about boost spike.

OOPS, sorry... Working night shift and was pretty tired. Here is a graph from my Link ECU. It doesn't come out too well when copied to the clipboard. I just reformatted my computer but as soon as I get it all put back together (getting my FTP program loaded) I'll upload a graph to my website and post it here with boost pressure vs HP/TQ.
13.6 @ 4681
13.8 @ 4934
13.9 @ 5289
13.9 @ 5539
13.8 @ 5896
13.9 @ 6239
13.6 @ 6756
12.9 @ 6957
12.9 @ 7035
You can see on the graph that the WG opens fully @ 7035. I really need to pull the turbo and port the WG opening a bit. I kill my boost trying to keep my pressure from getting out of hand.

working on mine, need to tune my solenoid better, had my targets off, opening too soon, I meant to keep it closed to the point where I make full boost. But still this log is showing 14.5psi at 4300rpm.
