i got a d16y8 and ive heard a lot of different rev points
my tach goes to 6900 rpms
i heard lots of people say take it to 7100 or even 7400
where should i shift to get the most out of it w/o losing power?

props_honda85

on my y8 my vafc read 71** as my rev limit in neutral and i think i a lil higher when i was in gear but never really checked it (hit it a couple of times but on accident but not really sure, it felt a lil higher than 7100) i always shifted right before 7K like around 6800-6900

i used to think mine hit around 7200, but i just found out recently that i can shift at like 7400 w/o hitting the limiter and it doesnt feel like im losing any power

According to the tach in my 97 civic ex, it's set at 6900. I don't know, don't care. When I boost and dyno I'll still shift at 6900

mine bogs out at like 7,200 or 7,300

the d16y8 rev limiter starts at 7200rpm if that answers your question...

Rev till you hit the limiter or untill you feel the power band drop, then you wut your limit is.

dyno it and find out where your power band stops increasing

not smart, tachs aren't always 100% accurate :-\ Especially at higher RPMs

like for example, I've brought my D16Z6 to 8k on the tach a few times..but I doubt it could do that because as far as I know the ECU is normal and rev limiter is 7200, so obviously there's some tach error there - and wherever u shift around there u'll still be in the power band no problem..

Redline and rev-limit are two different things.

EJ8kid

im not sure but i think the powerband stops around 6700 so i normally shift around there...

SCCrules

mine always kicks in around 7200rpm.

Jorsher

Right, redline is the safe place to stop and rev limit is for idiots that think their stock engine will keep getting more power as the revs go up.

LowSlow93Sol

for the y8 and the z6 the powerband peaks at 6600. Dont dare run it to the rev limiter. fuel cut at high RPMs = blown motor

boosted civic 2k6

wtf are you talking about. the rev limiter cuts off fuel so u get the bouncy tach. unless your downshifting and over rev, your not gonna blow a motor by hitting the rev limiter a bazillion times (figure of speech). so the powerband peaks out at 6600, some people take it further so when they shift they're in the appropriate rpms for that power. geeez.

Jorsher

Well, you can shift at the redline, still be in vtec range. Or you can go past the to the limiter, lose power, put extra wear on the engine. There's no point to going to the rev limiter, but like they said it's set at 7200.

6600: peak power
6900: redline
7200: limiter

speedysohc

so i get peak power @ 6600 rpms thats what i wanted to know thnx for everything guys

speedysohc

thnx 4 breakin it down 4 me

Jorsher

No problem

ekcivic9

is the d16 even making power up there?

speedysohc

you'd be suprised that little motor gets up

ive rarely drive it up there cause it just gets loud and it doesnt feel like im getting anywhere?

Jorsher

No, I really doubt it's making power up there. It peaks at 6600 then starts losing power... If Honda engineered it to still be making power at that rpm, the redline would be higher...
