I am experiencing a "dieseling" sound when I get aggressive on the gas. My boost is funky - it shoots up to 20-23 lbs and I do not have an adjustable wastegate... (I haven't touched it.)
It sounds like it's coming from that tranny but it's not (and the tranny is fresh).
Particulars:
86 GN
New Walbro 340/hotwire
NEW fuel filter
MSD 50LB
TT chip
43 lbs w/ vacuum off
stock turbo
dutt neck IC
62mm tb/matched plenum/rjc power plate
KB intake
LS1 Maf/ trans+ (not adjusted only set to base levels)
91 OCT (california gas )
I was going to add alky to "cure" the condition but I suppose that the condition should not be present at all. Also, noticed slight wobble on the turbo blades. They touch the housing so I'm shopping for a new turbo.
This wouldn't cause the dieseling noise would it???
Besides changing the turbo along with adding an adjustable WG, I should be fine, No? I don't know what else to do to fix the problem.
Any ideas?
I don't have a scanmaster yet... (soon very soon)
