i have a 95 civic..with 99 jdm b20.. jrsc. walbro pump, aem rail. 310 injectors kamakazee header 2.5 piping.... the ? is how high is to high 4 reving.. timing? right now im pushing 8 lb at 7500 timing is at 25 deg!! af is good (wide band) and no detonation that i can hear.... ps im tuning with chrome rtp.. im thinking of nos?? i have a dry kit in my garage.. i want 2 run like 20shot.. u know 2 cool things down in the charger.. what r your thoughts??

 

If your running 25 degrees of timming @ 7800 your iats must be really cool and you must be running race gas or really low boost if your not getting any deatonation. Have you checked your plugs to make sure? How lbs are you running? I would definetly run A LOT less timming on that setup for longjevity issues if your going to run more boost. SCs have notoriously high iats which doesnt help when it comes to deatonation. I wouldnt rev it much higher then you are now becuase the B20 head doesnt flow very well and I doubt that your making anymore power the higher you rev. Thats just based on the dynos that Ive seen with the stock head and boosted setups...

thanks 4 the reply... i check the plugs every week.. and they look good..im pushing 8lb...25 deg pump gas... the b16 and b18 i tune timing is like 19,, this b20 just loves timing.. but i stoped at 25 deg..because it seems really high...... best run so far is just 14.1 at 100.75 mph 2.3 60ft

 

IM'd you with a question
