L28 Turbo AFR + Timing

[Zed2k]

Just thought I'd start a thread on L28 Turbo 's for abit of research before I head back to the rolling road, If we can post

Boost

Air fuel ratio under boost,

max timing acheived

and water/ meth yes or No

intercooler, yes or No

This might give people and me an idea of what can be expected at which boost level etc , bhp (if known)

 

11.0 Afr

24 degrees

water/meth yes (but not tuned for yet)

Intercooler yes

15psi 315bhp

 

Thanks.

Simply look at the Megasquirt Map sharing thread. You can see target AFRs and some timing maps, all of which are plotted across RPM and manifold pressure.

 

Are you running an AFR of 11 at 5 psi? 2 psi? If not, then when do you switch?

 

What ratio of water and meth? 50/50? 80/20? There is more to this than simply Yes/No.

11 at 15psi and water/methy 50/50 but I will checkout the map sharing threads just thought It might be clearer on a seperate thread if not don't worry..

This greatly depends on the turbo used. For an example, for me 15 psi is around 350-360 rwhp.

compression ratio would be great to know also...

My compression ratio is 8.8:1
