This time of year is great for dyno Queen conditions ( nice and Crispy cold in the dyno room)

 

The timing between the two pulls was the same. I dont know why the variation was like it was, but the car was consistently at 370whp and did 371-377 on no less than 4 occasions. I have tuned enough stock cam cars at this boost level to know where the rpm peak would be, so I do not hesitate in saying they are stock. I also advanced MIVEC at idle to known levels that should have made even an S1 lopey like a Cossie and it didnt do anything. For the record it was 12* should anyone want to try it.

I have only ever seen one other stock cam car make this power and it was on an AEM meth kit and about the same boost at peak power, it did 371. Eric made 357 on stock cams on a stock turbo on a 29psi spike and somewhere close to that PSI out the top. If I knew what his exact license plate was I have the graphs with me.

Ryan.Kauz made 357 on SD as well and was also on stock Cams. He had one blip at 357 and was averaging 352 or so.

When you look at the corrected numbers it is only 11whp more than the highest I have seen previously which is right in line with the change to SD. I typically only see gains in the neighborhood of 8-11whp from that. All in all I think everything is normal.

 

Regardless those are some damn good numbers. Hell some of the first FP greens were barely going over that (at similar boost of course). Boost seems to hold well as also, that EBC seems to be working good. What was the peak timing, I assume probably 11-13 degrees? It is nice for power in the cold, my logs love the extra airflow but my a/f changes in the summer so I have to adjust it some.

Also curious about your thoughts on "winter" blend gas. I notice my A/F will fluctuate quite a bit more with this winterized gas. I assume it's because of the higher ethanol content in it. It does run like a raped ape though in 30 degrees.

 

It was 13-14 out the top, peak power was 12 as I recall.

 

great numbers!

 

Yay for cold weather tunes!
