BW S360 Dyno 477whp/370ftlb 20psi
 

After waiting out the break in period and slowly turning the boost back up on the rebuild from Angel Motorsports down in SoCal. I decided to throw it on the dyno when a friend came to visit Sonoma with his dyno to see what it would do. Two pulls both around 20psi with AFR's in the 10's with no ignition breakup. Everything felt good and put down 477whp and 370ftlb torque. Pump Cali 91 with water/meth injection

Now I was running the same setup with 3rd gen corner seals for a little over 4 years making identical power prior to this, but that one lost compression due to cracking rear corner seals caused by high heat? It was tuned for mid/low 11's and now it is tuned slightly richer with the new engine. Wondering if my timing maps had something to do with the last failure? Vid and screenshots of a log of one of the pulls with lead and split maps.

mate, I cant comment as Im no tuner. But this is the base and split maps I as given from haltech for a 13b. Just for reference

The adaptronic one from elliot here is similar to the haltch one as well.

I'd say your timing below 22 psi looks a little too aggressive. Congrats on the numbers though.

Yes they are

glad I wasn't the only one to notice. way too much timing. even with the meth injection that's aggressive

I didn't think that was too aggressive? I don't have an egt to tell if my timing maps are way off or not. I did have one person tell me that I may not be running enough timing combined with rich fuel mixtures that could cause high egt's. I have always went with 20 degrees lead @ 10psi and lowered timing 1 degree with each 1psi raised

Good power from an S360! The beauty of WI. If anything that timing is conservative. I've run 12 deg BTDC at 8500rpm at 40+psi with 93 gas.

silver FC, on a side note :) how do you get the haltech to do that blue tracking line? I only get the dot so to speak.

Just tap T on your keyboard. Hit the help tab and keyboard reference and you can see a bunch of different keys you can use for quick actions like F6 for start/stop logging on Sprint RE anyways

I tend to agree with you. Some of those people would shit themselves if they saw the timing I run with S4 N/A rotors and WM50 injection. Take the Haltech map and add 5+* and we're getting close to where my timing is set. And this is with more compression as well. I do tend to pull it back a little more in the high boost area's though depending on what the logs/dyno are singing in my ear

Also, you are completely correct though, or whoever told you, that running rich mixtures without enough advance will lead to high EGTS

Completely agree!
