I was wondering what is the "MAXIMUM" redline i can safely take my B16a2 to???.... i hear that B16's and B18c1's have the same valvetrain.... dual intake. single exhaust? .... i have a JDM small P30 ecu.. with what i believe is a Type R program.. the Vtec Kicks @ 5800//// and redline is around 8400-8500.

stock redline is 8000 for b16a2.. but i was wondering if i can take it to 8500 w/o doing harm.. thanks

also...i doubt i can take it that far and make power... i just dont want to float a valve if ya know what i mean

would 8200 be safe and still make power?

THANKS FOR THE INFO!



btw:: engine mods include

AEBS Intake Manifold
Hondata Cooler Intake Gasket
AEM short Ram intake
Comptech Stainless 4-2-1 headers
Tanabe G-medallion catback
B&M Fuel Pressure regulator
NGK Iridium sparks plugs

 

I took my old b16a sir2 to 9,5k daily never blew ran like a champ. hit the rev limiter acouple of times to rev set at 9,5k. vtec came in at 5k. stock valve train.

 

fuck....i used to take my ls up to 8200 daily. i have seen b16's in the upward 9's but they generally stop making power around 8100 or so.

The p30 program only pushes total timing of 26.75 deg with a revlimit of almost 8300 rpms & vtec activation of 5875 rpms.

I recommend a chipped ecu with better ignition timing & a vtec xover at 5600 rpms, revlimit where ever you wish i.e. 8900 rpms.

Concerning where a b16 stops making additional power you couldn't just assume every motor peaks at 7500 rpms. Every motor is different

 

thanks mtber for the info... hmm.. i guesss i was wrong about the p30.. i guess its just stock haha. So if my p30 is stock...... and the p30 was MADE for the B16's... that means i can take it to 8300 w/ no problem right??
or does the JDM spec P30 and the USDM p30 have somehting diff since JDM has 10.4 and the USDM has a 10.2 compresion ratio?
i just dont want to float a valve lol...

thanks

 

haha reminds me of my old b16 hatch.. took that bitch to 9200 daily, no promlemo. had jun valvetrain and ctr cams, don't know if that made any difference. haha, good times

 

ive seen them taken to 10 all day long but how long your motor will last doing this is beyond me.

 

i took my b18c1 up to 9,200 at the track and didnt notice till i looked at the tack...lol i got a modified skunk2 ecu with no rev limiter..i gotta get a shift light soon..anyone has a set of headers for a b18c1? im me..
