CarNRacer's Apex Motoring Alpha 16 - The DYNO!

December 11, 2014 0 COMMENTS 120

Well - it was the end of the season - but we got here. The tunes for these cars are tricky as we were again blazing a new trail in the modding world – at least in Canada.

From creating a smooth start up to ensuring the proper timing and power, there was much to tweak.

To say I was happy with the results, as early into the tuning phase that we are, is an understatement

With only limited timing and just under 27 PSI we hit 1117 awhp  with 802 awtq. That was more awhp than my R1K on GT3071R’s at full boost.

Even at this “lower” power level, the first signs of slipping on the dyno began to show.

Increasing slowly, and still without much timing, we hit 1345 awhp, but at only 889 awtq.  This was at 39 PSI.

Slipping on the dyno started to get out of hand, and we continued to try to weigh the trunk down with whatever we can find (and all of us).

Adding some additional timing and we hit 1383 awhp and 1029.66 awtq also at 39 PSI. Amazing what additional timing can add.

By this point there was major slipping now, no matter how many people or weight was added to the trunk. You can see the actual dip in the one picture in the gallery. Extrapolating the curve smoothly without the "spin sag" seems to show the top number closer to 1500+ awhp.

For the last pull for this session (and this year) was at 40 PSI;

1402 awhp and 1038.47 awtq. The "spinning sag" in the curve is even worse (it was actually present since about 1150 awhp) and we call it a season. Same extrapolation with a smooth curve seems to show the true top number around 1550+ awhp (this would turn out to be conservative as we eventually were able to add fresh tires and well get over 1600 awhp – but more on that in later Blogs…
