Anyone know where I can find some all motor d-series dyno charts? There are tons of b-series charts floating around the net but not that many for those of us who want to see how far we can take the d16a6.

only aaron, sean, and tyson are d16a6. cooper is a dx-mpfi. the rest is an assortment of LS, B16, S2000, greddy turbo Z6, and a crazy turbo'd EW.

There is some good information in those charts. Tyson, is there a writeup anywhere on the web (or that you could send me) of the mods to those cars and what things you were tweaking at the dyno? I noticed you were using a fuel pressure regulator (assuming that's what FPR on the chart is).

Thanks!

 

just go to http://www.norcalcrx.org and there is some chat about the day in the forums.

basically i started with a PG7 ecu, with stock timing. my engine has about 40K miles on it (from factory) and i raced it last year so i was just taking a baseline before i put another rebuilt engine in. but we played iwth the timing and got up to 111hp by advancing as far as we mechanically could without modifying the distributor, which is only about +5-6 degrees. then we added the stock PM6 ecu. basically, what we learned is that theres is no difference in the supposed fuel and timing maps between the two ecu's, PG7 just adds 300rpm. the 114 blip at the peak is not real data. then we put the PG7 back in and used a Z6 FPR. it made it richer, but no difference except at the bump around 4.5k. i am surmising this bump at 4.5 is due to the AEM CAI where the "tuning" kicks in and creates a resonant velocity stack funneling more air in, but only at that rpm, which leans the air/fuel out and the extra fuel from the Z6 further increases the HP.

now aarons intake is a focuz intake with a weird air chamber before the throttlebody and just a short ram. it seems to work better as it doesnt lean out and the gains increase for another 500rpm or so more than the AEM.

also, cooper's graph which models mine pretty closely, just lower, is a dx-mpfi and also has a CAI copy, and gets the same results as mine. just goes to show the cheap ebay kits are just as effective.

i am considering buying the focuz intake if i can get my hands on it. but it should go onto my new engine, which i plan on dynoing excessively aftwer i put it in.

 

Thanks for the link. The pics are kind of hard to make out peak numbers, though. Maybe it was just the computer, who knows.

This isn't getting me very pumped on building the d-series, I have to say. 120whp isn't shabby by any means (I'm not trying to knock you), but I have to believe the d-series is capable of more. A very sick b16 will make 120whp. I'm aiming for 145whp or more with 11:1 CR, lots of headwork, cam, cam gear, portmatched IM, and of course bolt-ons (maybe a Bisimoto header, maybe not). Am I expecting too much?

 

there are consistent results of getting 135whp, ive heard on report of building 170hp at the flywheel on a engine dyno, all with stock cams and pistons. just gotta know how to build em.

 

That wouldn't happen to be a black hatch would it:greddy turbo Z6

 

no, a white EG.

 

I'm actually working on a write up on the page. I'm collecting the mods and should get around to posting it in a couple of days. Check checking back the same link. Tyson the avatar is perfect.

 

170 at the fly is only 145 at the wheel?? you can get 10 hp out of a freak motor

 

you need to check this place out, promise me though you'll search before asking questions http://pub143.ezboard.com/bhondadseries
mini-me's put down some good #'s, last one I saw was 130whp and 111tq

 

Thanks for the link but I've already been there. There aren't enough people to make a great source of info.

 

the 170 flywheel number is another engine than the several other engines that i know were built to make 135 at the wheel.
