dyno tomorrow, really lost?

OK... so I'm running the following setup now... at 5psi. have my WG controlled by a vacuum line to the intercooler since there wasn't a nipple on the turbo. Mods are as follows:


FD fuel pump
720cc secondaries
550 primaries
Apexi S-AFC
3" DP - 2.5" MP - 2.5" duals
3" - 2.5" turbo inlet - cold air box - K&N filter
secondaries removed
s5 TII shortblock
T-04B V2 trim compressor, stock s5 TII hotside, mega ported wastegate
TurboXS MBC (installing it today... lol)
stock s4 TII ecu
stock IC

I'm going to the dyno tomorrow, they are tuning the car...

how much boost do you think I'll be able to run on 91 octane? 94 octane?

WTF do I do with timing? I don't even know if you are supposed to time with the mark on the left or right.
what target AFR's should I be looking for?
I guess they worry about all that so I don't have to but just incase they don't....

you have larger injectors and the safc to control them, so the stock intercooler is really what is holding you, you should be able to run 12 psi (prolly even 15) with out trouble if you add enough fuel and dont excessively heatsoak the intercooler on the dyno.

timing > https://www.rx7club.com/showthread.p...ghlight=timing

your in introuble if you afr's are above 12.5-13, keep them at 12 and under

i say at 5lbs and your setup youll make 185 hp

???
What are you trying to do? Retard the timing from stock for extra safety? If so, then go the left of the mark.

If not, then time ON the yellow mark

Make sure they tune you richer than a piston car. You definitely want to see mid 11's by about 5-6 psi, especially since you need the extra cooling supplied by the fuel to compensate for your the higher AIT's from your TMIC.
