My OFI kit Dyno results!
extremely impressive numbers but damn that's a lot of timing for a stock bottom end car.
Mine runs in the high 11's for AFR @ WOT typically due to where i have it set in the boost enrichment table (3 bar). but mine does go rich ( high 10's low 11's) during part throttle under boost due to a tuning issue i have not corrected yet.
Technically i could move to 20 PSI yet and 25* timing or so if i wanted to. It was doing 15 psi and 18 degrees with no methanol on straight 93 wth no knock. My AIT only shows a 15 degree increase over ambient w/o meth due to a decent A2A intercooler. It stays right at ambient or 5 degrees less when using the meth.
Its not a totally stock bottom end, i basically got rid of the TTY bolts and glass-like pistons.
I drive this thing around set on kill all the time and i pound the **** out of it quite a bit... it hasnt done anything stupid at all suprisingly, and drove it home in stop and go traffic with being 93 out and never got above 200.
I got in a 3-way run from a roll, and it really was like a Jet. It was him, I and a Mustang, and intitally I pulled out then you hear this jet-like sound and he goes flying past. Turbos on v8's are badass! This was when he just barely had it dialed in with low boost. I'm scared to see what it's like now that he doubled the boost.
The Best V8 Stories One Small Block at Time
Coasted to a 12.017 @ 130.22
bogged the launch, 2.0 60' spun in 1st-2nd, hooked in 3rd and the clutch slipped BAD, (never seen over 10 psi boost till 4th) Got into 4th and the clutch bit and got up to 15 psi finally and i ran out of gear about 300 ft before the traps ( 4th taps the rev limiter @ 136) and when i was about to shift into 5th i realized the clutch would not allow me to do so, ended up caosting through the traps trying to pound it into 5th.
So time for a Spec super twin, trans freshen up and some diff gears. Stay posted for better, non supra like performance.
The exahust is an SLP 2OTL.
BTW, the 2OTL has always been one of favorite sounding exhausts out there...
Now that i got the part throttle tuning working better its not rich going into boost anymore like it was on the dyno. It makes 10 psi by 3200 now and 15 psi 3700 if it doesnt start spinning first. Where on the dyno it was rich going into boost and would slow the spool up and would hit about 4500 or so.
Got a spec stage 5 on the way, trans synchro kit and 3.42's and new drag radials ( i killed in 500 miles w/o one stationary burn out or hole shot lol)
Need to find a 2 step too yet.
I really want this to be a pull up and run right off the street 9.90 car before the end of the year.
Yes it feels WAY better than the 200 shot ever did on its best tune up. Its like the nitrous hit... ALL the time lol
Only saw about 13 psi and got a tick lean at about 12.3
Nothing really changed engine wise since the first time.
693 HP 743 Torque Got any stumps that need pullin???
It was acting alittle ghey on the dyno, but if it got a full psi and the same 11.8 afr it does on the street i would say 720 and 750+ were in line.
I will post the graph later
