Braineack's newest dyno plot (11-10-07)
 

Threw it back on the dyno after my headwork and exhaust. very pleased.

I had issues with my EBC as I got it working 5 minutes before I strapped on and didn't tune it well. It's making boost faster than I accounted for so I got a slight boost spike and it creeped a tiny bit. I was trying to keep it as close to what I've dynoed at before to be able to really see the effect of my mods. I couldn't use the same MBC as it's rendered useless now with the amount of boost creep I get with it.

but here it is, note I pulled up top because I heard ping, although no one else did. But I was playing it safe and I'll tune my spark map one of these days. I do not hear/see any ping on the street...

I was looking over the charts during the dyno day and found Phil's was very close to mine up top so I will assume this is exactly how my power would have looked at redline:

and here finally is the before and after of my work. This is prior to MS, the headwork and the exhaust. I superimposed the boost levels on the plots so you can see it's realively the same boost level. Look at that spool now!

I bet if you add some gasoleeen to get closer to 12 or 12.5:1 you'll get rid of that knock.

fuck started getting lean eh? I start getting close to 13 and I shit my pants lol.

The spike @ 4.5K on my datalog show 12.8. at 6k when i pulled it was in teh 12.5:1 area. I added a tad more fuel for good measure and pulled 2* past 4K. I dunno it might not have been ping either, but again I was playing it real safe because I'm tired of things dying and I had to drive 2 hours to get home.

whats your spark advance looking like? if you dont mind sharing.........

Real bitch how slow that S60 spools eh... Should have gotten a GT28 BB unit! LOL.

Mark

yeah great advice you gave! :vash: :gay:

150ftlbs @ 3250 = :bigtu:

sideways @ WOT in 2nd = :noes:

:skid:


not really. fwiw, it's spooling about them same as Tom's gt2554R...however he still has his stock cat on it.

oh that's RIGHT, no cat. no wonder it spools. it's not ALL head work :)

Don't hate Matt!

i'm not hatin' i'm proposing that apples are not oranges!

I think joe would agree that apples and oranges are in fact ducks!
