Timing?
I'm curious to know if I'm on the "safe" side of things...
I'm running just an S5 13bt mild streetported with cleaned up exhaust ports... Turbo is just a T04B comp. housing and T04B V-trim wheel on stock turbine. I make full boost (11psi) by just under 3700rpm and it holds all the way to redline (7500) Now since I don't understand how to use the print screen buttom (I'm stupid), here is my timing as best as I can do: Timing vs RPM: idle = 10* idle - 3000rpm = gradual rise from 10* to 28* 3000 - 7500rpm = 28* Timing vs Pressure: 25” - 5" = (0*) - (-2*) <~ "0degrees to 26degrees" 5” - 2psi = (-2*) - (-6*) 2psi - 10psi = (-6*) - (-14*) 10psi - 14psi = (-14*) 14psi+ = (-18*) - (-20*) Since I haven't dynoe'd yet, I don't know where my peak torque is. Overall, do my figures look alright? |
Here is a 2nd gear datalog that shows a bit of my timing... does this look ok?

i am also going to be workin on my S5 with an e-manage and i will too have the timing adjustments
Biggest issue i have is that i do not know what the stock setup is and the rpms increaase and weel as how the timing retardsas boost goed up |
Aren't you having Dave tune your car? Dave should have a good idea what he's doing ;)
|
ill let him try , but only if i concurr on what he is doing and why.
|
No worries, Dave is awesome and has a pretty good idea on what he's doing. Be sure to ask for a ride in his half-bp 62-1 FC (assuming he has the motor in there already)!
