Just did some research.. No wonder... The stock Speed 3 put down 216/243 torqe... the SI put down 180/143tq...
Huge loss in power from the speed 3 compare to the SI though.. % wise.

Nice find, but one thing about most mazdas is this.... No cool air going down the road, ECU kills the shit out of timing. If you were to look at the A/F ratio, I garunteed it would drop well below 10:1. I bet when they tested it, it was during the middle of the day. I think Sport Compact car did a baseline dyno run on a stock '06 Miata. during the day when it was nice and warm, it could only put down 133whp. They didn't know why. They tested it again later in the evening, and due to the cooler temps, it put down like 145ish whp. I even had that problem on my old 4 banger. My A/F dropped to 9.6:1 and I only made 106 whp/128wtq, and it was real humid in the shop. I don't know what it would've made if the A/F were the way it were, but it would've been alot better. Besides, how many times have you heard of an almost 3200lbs car running a 14.0 flat with 215whp?Originally Posted by Julio
K series 626. That's right. It's got a K in it.
