sorry been here for nearly 3 yrs and i still dont know how to post pics

this last weekend noahk hosted a norcalcrx dyno meet at Race Prep Eng.


my set up:
-1990 CRX DX w/ jdm B18C AUTO stock usdm OBD1 P72
-stock internals
-Skunk2 IM
-Comptech Header 4-2-1
-custom bent 2.25" hi-flow cat and exhaust
-CM stage 3 clutch and lite fly
-"15 azenis

1st run: (blue) had stock intake and paper filter
2nd run: (red) pulled the intake box-just tube-how i run at the track
3rd rungreen) adv timing +3 degrees and no intake box

between second and third run i lost peak HP of about 6hp but i sure gained alot midrange...Noah told me that it was well worth the loss in top end for the mid range gains...wonder if it would help or hurt me on the track...

what do you guys think?

i know its not the best baselines from a b18c but i sure have seen worse...

Ryan<---next mod JRSC!!

p.s. you get the homie of the day award if help me host this

 

whoa, bitchin' midrange gains with the advanced timing

damn...i wish i coulda gone to that too...wanted to see how much power i'm puttin down...but anyway, i think you may do a little better at the 1/4 track...depending on which tranny you're using...i'm thinking about .2-.4 seconds difference assuming your normal racing conditions (launch, temp, traction, etc)....

use this: http://crx.honda-perf.org/math/index.html to look up where your rpms will drop to when you shift...if you fall within your powerband, you'll (theoretically) improve your times

CLICC916- yea the dyno meet was cool....drive to chico was hell in my crx...you going to sacraceway anytime soon?


JAMinCiViC- thanks HOMIE...i appreciate it

 

yea i was up in chico too, but i was at an education conference...long boring ride to chico...unless you're topping out your speedo on I-5 ... might go to wed. nights sometime soon...maybe within the month or so before it gets hot and before i have to mess with my car for smog...grrr

 

go on the 26. EFs represent!

 

the 4rd run (green one) is def. better as you don't have a nasty vtec dip in there. the hp curve is pretty linear which is good.

 

so your timing was a 19degrees ?? good to know what u get when u advance timing.

 

yea it is at 19 degrees right now...im wondering with the increased power in the mid range i probably going to have even more trouble with traction at the track...i usually have problems keeping the tires planted from 3.5k to 5k which is also where i gained...looks like i need to spend $$ on radius rods and some drag radials...

 

i think that incorrect ground location got u

 

what tranny are you running?

 

does that say auto? as in automatic? is this a jdm type-r or gsr engine? im guessing if you are running a P72, that means its not an auto, but what does the AUTO mean? BTW, good runs if it's a gsr (guessing it is since you've got a skunk2 mani) i'm also guessing it used to be an auto. good luck with it, mang. any dyno vids?

 

he has automatic cams inside his motor.....
o yeah i have my gsr cams here wuhung lol i forgot about you...

 

yes the motor was originaly and automatic in japan(came with a auto tranny and auto P72)...it is now mated with a Y1 in my crx...its also now using a usdm P72...

XtraFastCRX- yea man remember we were suppose to play some baseball with my cams when i got em out...hehe

...and Rob, my ground was just fine the way it was damit

 

no, u still stink
