tuning guru's chime in
Well today we had a dyno day. at a local shop i have a b16 .20 overbore 9.0cpr street tuned my self 15 pounds on lo cam high cam 20. my first question is the dyno when we did a pull i only could boost 17 psi. but to my suprise i pulled off 301.9 hp and 194.6 tq the only thing that has me thinking is my max hp was at 8150 i redline at 8800 and tq was at 7600. I think it maybe a timing problem but im not positive my af at peek hp was 10.7 i know that is pig rich but i like to play it kinda safe. What can i do to get more mid range power.

tire/rim size, gearing, more tuning, better cams, timing, etc, etc...

20 pounds makes B16s fun. |
Re: tuning guru's chime in
thats another think my car has a boost creep when vtec ingages i creep 20-22 psi but on the dyno i only got like 17.6 then boost fell off i added more timing to my map today the car spools faster and pulls a lil harder i think ill go back to the dyno to clean up my tune a lil more def need to fininsh my det cans though

20 pounds makes B16s fun. HP=(Tq x rpm) ---------------- 5252 You do the math, only reason b16's can post high hp numbers is due to high rpm capabilities. :P |
Re: tuning guru's chime in
Dude a 300wtq Honda engine is going to be making like, 500whp.
I'm not hating, just saying when you throw enough boost at them they make fun street engines. I tuned an 84mm B16 with a 57 trim on it at 18-19psi a few weeks ago that is a rocket ship, even if it's not making a ton of torque. |
