Yesterday, I had the awesome opportunity to have some free dyno runs! I was attending a car show down in South Florida at JM Lexus, and as part of only a $10 entrance fee, show cars were allowed free dyno runs and food! In short, the best 10 dollars I've ever spent on my car.
This dyno was done with only Berk Technologies HFC and HKS Hi-Power exhaust. Everything else is completely stock. First pull was in 4th gear, and second pull was in 5th.
For comparison, here is my 100% stock dyno sheet I had for my car. Again, first pull in 4th, second in 5th.
From what I can tell, I got an increase of +19whp and +11wtq! Of course, I know these are different days, temperatures, humidities, and dyno companies, but, hey, can't beat free.
Something I would like to note though - I ran my car on the other dyno, and it happened to be the same dyno shop that ran my bone stock dyno! However, I was put on the dyno at about 12:30 in the afternoon, and the air temperature was extremely high. I peaked 297whp on that Dynojet. The 305whp run was at 3:43pm, where the temperatures dropped.
I'd be interested to see how much power I can put down when the temperature drops to about the same as my stock dyno was. A difference of 13 degrees could be very noticeable.
