Power FC Single Turbo Tuning
Single Turbo Tuning
First let me says thats for emailing me the famous tuning notes, it is excellent. Now I have been finally cruising aroundin vacuum tuning the car,so far so good. I have three questions before I go into boost on the dyno:
1. At 12psi, pump gas, with a T76, what should be a good average rwhp? I need to know if the tuning is okay so far.
2. At 12psi, pump gas, what is a good knock average and maximum?
3. I have the timing split safely set at 15, how low can I go at 12psi?
Thats ot folks..no maps need, just some honest experience one word answers. I will forward to results after a couple days of response.

1. At 12psi, pump gas, with a T76, what should be a good average rwhp?
A. Depends on other mods that affect intake and exhaust flow. Over 300whp.
2. At 12psi, pump gas, what is a good knock average and maximum?
A. Varies for every engine but I never like over a max of 60 on a quiet engine.
But then some engines are noisy even off boost which then invalidates this.
3. I have the timing split safely set at 15, how low can I go at 12psi?
A. 10 split. Search on my recent post with a display of split on this forum.
No need for 15 split below about 6 psi boost.

Thanks Chris you always help...thanks again
THanks..i will check out the post. I notice alot of people have zero spilt in vacuum. Can I change that now?

Exhaust has not Cat, 3-inch downpipe and piping, Aftermarket airfilter. I will use to get an idea of how healthy the motor is.

Okay..I have yet to see over 30 knock so far.

If you find my post that I mention, it shows all.
Who do you recommend to purchase plugs, wires, etc from on the forum. And what plugs would you suggest for my setup?
NGK B9EGV or B10EGV plugs which are gap adjustable and non resistor also work towards a hotter spark. (requires the thin wall socket or enlarged hole in the rotor housings) Most motocycle shops carry the plugs.

I have seen knock values as high as 50 when just below positive boost pressure (usually when starting from a stop), but have seen about 7 psi thus far and the knock values while in boost average about 30.
A quiet engine/car is one that you can drive around from idle to low boost and knock levels are below 20.
Mine is a little noisy due to the diff I think. But once on boost and all drive train slack is gone, knock(noise) is below 10.

I did a 10 psi run today and didn't see any knock above 20, but like I said below boost I see upwords of 40-50...I guess that could be drivetrain slack or worn out motor mounts.?
