where is the sweet spot with this turbo? I have it at 22-24lb now with alky.
With stock heads and cam over 30psi.
guess I need to do some more tuning and turn this sucker up.
What are you running with it at that boost level in the 1/4 or 1/8?
bought the car in Oct. Will race it the 25th in Dallas.
Cool. Please post results.
ran an 11.91 at 22lbs. 1.76 60'. 112mph.
Thanks for posting. I'd think you would mph a little better at that boost level. Are you using a wideband?
I'm at 112 mph @24lb looks like I need to work on my tune, one pass at 114 but 1.5 KR so I pulled the timing back
I suppose those are ok mph's. I looked at some old slips and I didn't do much over 115 @ 25psi on my stock longblock.
I believe it's like an old 49...
Bison is spot on. I ran my 49 in the 28-30lb range daily. With a 3200 stall, that thing flew to 28 and it was awesome.
The cea wheel will work better at a higher pressure ratio than the old t04e 60 wheel. Under 25psi on an engine that flows under 45lbs/min there probably won't be any gain at all.
Just did a 206/206 flat tappet and mild port on the heads. Will it still need the high boost?
You should be able to hit almost 60lbs/min with that turbo. The junk engine in my blue car reached about 60lbs/min at 30psi. The engine had heads with cleaned up bowls and a good valve job on stock valves. I ran a low lift cam with 212@.050 duration. The car trapped about 128mph in this configuration and tune. So I wouldn't expect to have 10 sec power below 26-27psi with a good tune. The bowl cleanup definitely helped the straining 60-1 in my combo. Porting isn't worth anything if the bowls and valve job aren't addressed.
