We get the SVO ready to go on the rollers and see how much it makes with and without "Premium mode". We add the manual boost controller that came on the car and see how much power it has before we start making changes.
So actually right in there for power considering that oem hp numbers were only 175hp. But the knock sensor should be a round connector I think. The connector you showed is for a code reader.
We are not familiar with these 2.3 engines at all, we did the few minutes of googling trying to find which one to unplug. It will all be coming off soon with hopes to run an aftermarket ECU.
About right, I guessed 160. Would be good to know the fuel pressure on boost, I’m thinking the pumps are old or the filter is almost clogged. I’ve ran a wide ban on my 86 PE computer and it goes horribly rich with any load, like 9’s, then slowly comes back up. Check your timing with the ‘sprout’ disconnected, should be 10^ initial, for starters. The timing map under the highest load maxs at 24^ timing with 10^ initial, more than I originally thought but the compression on these are only 8:1. Tune it old school!
Forgot the 84’s had the ‘PJ’ computer with 30lb inj, which the timing tables are a little weaker than the 85.5-86 ‘PE’ computer. Look here: Rothfam.com/maf/tools/PJ_timing.jpg
Something isn’t right. It should be holding at least 15+psi and be making a good bit more torque. Excited to see what it does with a dominator and more EFI control.
Electronics is the main hold back I’m sure. A stand alone system , nice tune up, and I’m sure it could get bout 200 at the wheels with stock engine and 15lbs of boost
did you not log fuel pressure? The SVO had dual fuel pumps. They're known for failure. Filter can be plugged. Regulator can be failing. Sock can be plugged on the in-tank pump. At 16:1 A/F you certainly have an issue (obviously) and it's just not going to make any power at that a/f. That is assuming there is no exhaust leaks which would partially explain the a/f. Typically these old dinosaurs run on the rich side which is why they respond so readily to increasing the boost level. Common mods are air filter right on the end of the VAM, gillis valve, and 3" exhaust. With 18 psi and those 3 mods alone, should be easily 225hp on the rollers.
@Brett Yarborough IIRC, the PiMP is a megasquirt3 based, and the best part of it is you don't have to re-wire anything. I think these guys are going MAP only (no VAM or MAF), and I wonder if I can do that with the PiMP. I'm also thinking strongly about the Speeduino, that is also MAP only. But their results (next video) make me doubt the eecIV ECU. PiMP can do flex fuel, Speeduino is working on that, haven't checked if the Holley can.
From the factory those cars were rated at 175/210, your car is not that far off. What are you complaining about? It's a 35 year old car....a well used 35 year old car. I think this is quite a nice find a will make for a good project.
