I think I know why I made less power than I thought with my head swap.

My previous dyno sheet said I dynoed in 102* temps yet it was March 22 and I remember it being 60*. Well std numbers correct back to what I should be making at 60* So it adds hp to my final numbers. The program thinking it was actually 42 degrees hotter than it really was added a lot of hp. I probably would have only put out around 470-480 if the program would have used the correct data in figuring out the std numbers.

I mean it did put out 516 at 12 psi on stock heads and intake which is unusual.

This time the temp on my dyno sheet said 86* which was accurate so it used the right data to figure the correction, So it actually made 520 this time. Which is 40 -50 hp more.

Here's the run conditions of my previous dyno when I did 514/452. Correcting from 102* even though is was only 60* skewing the numbers


Here's my last dyno sheet from last Tuesday. Here the temps recorded reflect the actual temps. So there wasn't as much correction as the previous time.


So basically the time before the numbers were over inflated and this time the numbers were corrected correctly.

I also broke 500 before 6k this time and it took to 6200 the previous time.

Here's both complete dyno sheets

I wish he would have turned a few more rpm and worked on the drivability a little more.

I also whooped me a cl600 coupe tonight. He pulled beside and asked what I have in it. I just told him a Sc. then the light turned green. He started a couple cars ahead. When I started getting on it and race was on. I ended up about 8-9 cars ahead of him by the end of fourth. He was cool and gave me the thumbs up the.

It just feels alot stronger up top to me. About like it used to in cold dry air even though it was hot and muggy tonight.

Yeah I feel a lot better. I kept wondering why I had so much fuel left at 515 when I was only running 42lb injectors. I mean I was at like 85% duty cycle. The reason was I was not really making the hp as I thought I was. Thats about where it is now with the 60's

My car has a good bit of weight removed. probably 300lbs or more. Now I need some weight reduction.
