I just went and did 2 back to back runs, had a new fuel map to try, so figured while i was doing it i would play with the timing map a bit too. so i took the first map and just changed the timing map a little and saved it under a different name.

Red line is the first run which is the lower timing one, Blue line just had some fueling changes, Green run is my previous run before today.

i think i took to much timing out of the middle, but up top seems about right.

that was on 12psi?
2012-06-14 23:53:54
yep, all 3 runs were on 12-13psi

I dont know if that first run was a fluke or something, but so far with this program the numbers have been pretty consistant. I think if I add back a little timing it'll get rid of that dip. Not to mention it holds out power pretty well, I might have to invest in some s&r's, But I think if it comes to that I'll do it when I build the bottom end and maybe even run some different cams. I haven't really decided how far i want to push it, I want to build a 400whp car, but only really run 250-300 to save on transmissions an such lol

Nice, keep going. You're getting there.
Hmm remind me, you have a gtir t28 turbo right?
2012-06-15 01:38:38
PTE-5128 aka GT2871R but with slightly different wheels and a 35r style comp housing. .86 on the hot side.
2012-06-15 01:41:44
Ahh, What's the compressor map like? You may be able to make 400 whp on it
2012-06-15 01:42:25
Mmm i am almost erect seeing GT2871R, I think that's the best t28 flanged turbo to use

not sure tbh man.. I think its good for 425 but is suppose to have some better characteristics over the normal 2871, they come in several flavors though, some will do 475, some 450, some 425. I'm really only lookin for about 300whp and I think I can do that on this engine, but I dont expect it to last along time lol.

One thing I know is the intake and exhaust wheels are 51mm even, most of the 2871's have mixmatched wheels, not really sure on the effects of all this lol.
