@ Danzzt231 I used to have a Honda S2000 in 2002, so I know what you mean. I also used to have a Clio RS, which had a much flatter torque curve, and it was much easier to stay in the "good" power band. This engine seems to give you enough torque to have some guts while driving slow in high gears, but it's nice during spirited driving, so instead on concentrating on filling the "valley" we should think about incresing horsepower in the upper range.
This has revealed to be much harder than we thought, unless you work on the headers there's no way you get more than 3-5 hp.
I'm also really skeptic about intakes, on our tests they usually give less power than the stock setup, especially on NA cars. |
Lol, I'm trying to bring the thinking process on this out into the open a bit more, not 'testing' you. Different perspectives help me, too.
What about wave transfer from exhaust to intake during overlap? Also, low pressure returns during exhaust valve opening can help pull out more spent charge even without overlap.
Changing the exhaust primary lengths is what moved the dip lower in the rpm range. And the stronger drop is from wave transfer during overlap, since the AVCS haven't been adjusted to reduce overlap in that rpm range.
In my non-professional opinion.
