Went to a dyno day on Saturday and with the new injectors and different turbo I wanted to see what it would do @14psi. The first run was at 10psi then the rest was at 13-14psi. There is probably more in the setup, but I'm just using a map that I made from using other peoples base maps and from reading around the forum. The AFR's where around the mid 11's. I still have to get around to leaning it out some around 4700 rpm and richening it up a few points at around 5400 rpm

Nice Numbers!

You've proven 350hp can be done w/ rtek 2.1!

Here come the 11 sec passes...

 

very nice, i only made about 310whp at about the same boost, same basic mods except for a bnr stage 3. my fuel correction is maxed above 6k rpm and it still runs leanish (mid 12's AFR), max d/c about 80%. What fuel correction are you using and what d/c are you seeing

 

The correction for me at 14psi is 13.2+% 5120 rpm's and above. At 12psi its 8.2% at the same rpm's.




@ 6512 rpm the duty cycle is at 85%. Above 6888 rpm its in the 90's. So I'm about maxed out right now.

 

nice, your airflow is way higher than mine, i mine never gets above 700.. which may be why i run so lean. softer afm spring?

 

No I don't think so? Did they make different springs for the S4 cars? The AFM is stock.

 

Very nice graph, you have ample area under the curve and a pretty flat torque curve as well. I bet that thing feels like a beast on the road.

 

nicely done!

im really trying to figure out why we can wire up cobra mafs?? or try something along the line of a speed density set up?

also im going to try out a 300zx tt fuel filter and put my walboro back in a retune for 15 psi but i need to recheck my timing

could you gimme a break down of what your timing looks like above 3500 and above 6 psi ?

 

Brush up on your understanding of speed density systems and you'll understand why it's not as easy as swapping sensors..

Though replacing the MAF with another type that puts out the same type of signal would be a bit less involved.

 

i know this set up is quite new to me just a friend with a dsm was telling me about it and its sounds pretty good so thats why i asked
