Alrighty I have a sb350 crate motor totally stock however not sealed. (Freshened rod bearings/0-gap rings and new replacement valve springs etc). On top of 1 race season, There are probably a few thousand additional HARD miles on the engine after small refresh listed above. Ran 3 race seasons total of circle track with this engine at 50 laps a feature and never skipped a beat. I swapped this engine Inti to a 91 2door swb gmc sonoma pickup. It has a 750 4 barrel with a blow through hat. Haven't messed with jetting since a/f ratio on boost is where I want it for now. Not running an intercooler at the moment. Turbskies are off of an early 90s? 7.3 Powerstroke one on each home made exhaust header, so it's a twin turbo set-up. Max boost is set at 7psi at the moment. Timing is around 22 degrees(no controller) and it's running a steady 11.9-12.2 a/f ratio at full boost. Now, at higher rpms the timing seems to retard itself about 4 degrees or more and I can only assume the cause for this is the non functioning alternator for which ive kept for the ease, but I'm using a yellow top gel cell and run all over town with no problems. Been running 93 from the pump mostly but filled up with 110 at the track so roughly 80% in the fuel cell is 110 right now. This is all backed by a turbo 350 that's had some work done. (Shift kit for sure maybe drilled and refreshed/Maybe mildly upgraded internals not sure). Tranny is holding fine (somehow) with radials and a 10" 5000 stall with aux. cooler and showing no signs of letting go. Out back is a ford 9" narrowed for radials with cust. Strange 33spline axles and 3.73 gears with a true posi setup. Removed all but 1 leaf spring leaving a half 2nd leaf for layover and threw on some homemade track bars. Cam is hydraulic flat tappet with stock spec lift at .435 Intake/ .460 exhaust and 212/222 duration @ .050 with 112.5 lsa. Factory 1.5 ratio stamped rockers and stock valve spring rates. Comes in crate with a dual plane high rise Intake and vortec heads of course. Crate come with Hyperuetectic pistons and powdered rods. Running mechanical fan directly with no thermostat, and aluminum radiator.(have to double check size) When I install working alternator I'm going to install an e-fan to a switch for the gains, response and to cool off between runs. Anyhow, ran it at the track last night at a 1/4 mile track and made 3 passes 1 being a full pass and 2 1/8 mile. No issues at all and 1st pass ever at a track (being the only full one of the night) and ran a 11.81 @115 mph with a 1.87 60' foot and 7.80 something 1/8th mile but when I stalled up at the tree the boost powered through the brakes and I just barely hit A red light before taking off. 2nd run in the 1/8th was a 1.67 60' foot and ran 7.67 et @93mph. Only change between first and 2nd run was removing air filters on turbskies. 3rd run was quickest with a 7.43 et @ 95mph with a 1.62 60' foot. Not bad for first run ever. Anyways this post is for advice and not to tell my story but I thought some info on the setup was in order for further advice. Air/water intercooler is coming soon along with alternator and e-fan. Also considering heat blankets for exh. Side of turbos.? Hopefully that will help overall heat soak in the engine bay and Intake side of turbos maybe?? And timing controller is top of the list. Considering everything I've listed what kind of boost do you think I can push safely with the current setup I'm running? Any advice on JUST tuning that would allow higher psi safely? Also plan to expirament with either 3.42 or 3.23 final drive because the 1/4 pass Resulted in roughly 6k rpms at the finish and I assume that with the stall and boost it will pull the lower ratio no problem. Comments and advice are welcome!
