doesnt the p2p ecu have a rev limiter of 7400? My mini me only revs to 6800.. any suggestions?

 

its prolly not a vtec ecu thats why. non vtec ecu is 6800, vtec ecu for sohc are 7200

7000 rpm for a Y8, 7200 for a Z6

 

?? My y8 revs to 7.4 easy.

I bet your tach is inaccurate, especially if it is the OEM unit.

Stock tach is bullshit. Per the HELMS manual, fuel cut off is 7000 rpm on a Y8.

 

yeah my fuel cut off is at 7k even though the tach says about 7400 with my y8

 

Hell I wouldn't trust going to 7,000 RPM with stock valvetrain. I don't know why some people want to go up so damn high.

hey my ecu is chipped to rev up to 9800 and i'm gonna rev my stock *** VT up to it and watch my motor blow up

just because an ecu can rev up to a certain point doenst mean its safe to take up there

True That!! the reason for lots of blown motors, lowsy power gains, and pretty much a soon to be ruined ride.

 

oh yeah
my LS will rev to 7200 rpm and i take it there MULTIPLE times a DAY and i have done so for the past 9 months. I say if you wanna rev the **** out of your engine by all means do so. oh and did i mention that my engine has stock valvetrain

Are you serious??? If you really think that, please sell your Honda and get a Chevy!

 

stock y8 valvetrain is good to 7800. (with a stock cam of course)

Ok there buddy. I didn't say I shift at 5,000 RPM. If you can safely rev that high without wearing out your valvetrain substantially then why do most SOHC VTEC and NON-VTEC motors have their redlines anywhere from 6,200 RPM to 7,200RPM? My Honda Accord EX (F22B1) SOHC VTEC redlines at 6,200 RPM and fuel cut off at 6,800 RPM or so. D15B7 has it at what, 6,400 RPM? I say take it to redline, that's it. If you're trying to pass your redline and be m4d tYt3 s0Hc vTak jDm y0! then go ahead and further wear our your valvetrain. If you have upgraded cam(s) and valvesprings and some block work, go ahead and go to 10,000 RPM. If your **** is stock (internally), have a nice day.

Oh, and I do rather have a Chevy than a Honda, by all means.

But 7000 rpm is the redline on a Y8...and yet earlier you said...

Pick one!

And a F22 needs a lower rev cut since its a 2.2 liter engine, and the more displacement you have the less it wants to rev higher. Kind of like comparing a small block chevy's revving capability vs. a big block chevy. The big block doesn't want to rev like the small block since the internals are heavier.

Its not rubbish! And yes, I know what I'm talking about. I just didn't get into the other aspects of things, like bore and stroke combinations.

My personal favorite engines I worked on only had a 1.75" stroke, 2.65 liters, and reved to over 16k rpm.

Then you do know what you're talking about, my apologies - so don't make generalized statements, they cause confusion.

Next thing you know, some newb will be repeating it elsewhere and making themself look like an ***.

That's not always true. Some of the big time V8s rev past 6,000 RPM.

I was talking about the D16Y8. Saying the redline is 7,000 RPM and trying to shift at 7,400 RPM is not a very smart move.

BTW, how about the H22? It's a 2.2. What's the stock redline of the H22? 7400 RPM is it? More displacement doesn't necessarily have to mean lower RPM.

 

i never actually shifted at 7400, but once or twice to warm up the car real fast
i revved the engine very high and both times it hit 7400 (according to the tach)
with no cut off. I shift at 2500 normally.

 

i just read this whole thread and its just a big pissing contest...jesus christ...

[QUOTE]

no one even said that, damn learn to read, they said their stock tach says 7400 at redline, then it was mentioned that the stock tack isnt accurate and even though it says 7400rpms the engine is at 7000.

 

By the time I got to the end of this thread I had forgoten what the original question was.

After rereading the question I have one for you guys.

If his redline is 7-7800(depending on who you ask), why is he being cut off at 6800? The helms says his engine cut off is 7k. If he's showing 7400 and you guys are right about the tach being off 400, then wouldn't it mean he's actually getting cut off at 6400?
