+1

 

still playing a little with it but here ya go .. 25psi at 3500rpm tapering to 19 at redline

11.7 at peak boost tapering to 11 at 7k .. if i push it up to 11.4 at 7k i get about 20 more hp.

 

What fuel are you on?

 

93oct, 3.5 ets intercooler speed circuit cai 3port and test pipe

BTW this is at sea level too with an occasional 1-2 knock count

 

i'm no expert but it seems like you should be able to run 4 to 5 degrees more timing pretty much the whole way.

 

If I go much higher I start getting some knock I could try adding more fuel but typically I was getting better power up top with leaner fuel then more timing but hey I'll try it out this weekend

 

heres my timing map, a little improved. 93 oct, mods are Perrin Drop-In - UR UICP - Tomei Expreme Catback - TopSpeedPerf 3" Test Pipe - Walbro 255lph - GS3port EBCS . peak boost 25.7 (for now) tapering to 22psi at 6k and 18psi at redline. AFRs being 12.5 spool, 11.5 peak, tapering to 11.3-11.2 at redline.

 

Depending on the quality of the fuel, he could run 2-3 more degrees safely

 

Wow. Thats some of the lowest ignition timing I've seen for 93.

 

Man that looks WAY different than my map. Mine is for e85, but even cruise/idle stuff is way different.

 

added more timing last night. around what timing numbers should I be running?
still workin out some knock at the moment.

 

do you have any datalogs that go along with that timing map?

 

There are multiple factors that will determine what is safe timing for your car from spool to r/l. What I've seen is 15-20* around top of band depending on mod's and psi on 93. Weather is also a factor.

 

Anything over 17* at 7k is too high for 93 on the stock turbo IMO

 

You can't drop a blanket statement in there without qualifying it, lol. At what boost... And mixture? 15 psi & 11.0:1? 17* would be far too conservative a finger-in-the-wind target to have in that specific situation...

What boost/load level do you have in mind for that 17* ?
