rb25det off limiter bogging

[RYanR31]

sometimes, well most of the time i have it flat stick or slight throttle it bounces off the limiter and bogs down, missfires and slowly looses revs and power, its like what happens when your spark plug gap is ****ed...it was doing it with a gap of .8 then i went to a .7 but still does it. if i back off and back on the throttle it will sometimes get better but once it hits the limiter again itll bog down, missfire and loose revs even with foot flat or slightly, its like as if its surging out. this is mainly halfway through a slide (off street). all i want it to do is bounce off the limiter cleanly for peace at mind.

whats a solution? should i close or open gap more or is it something else? timing perhaps? i got no idea

cheers.

It's the way the limiter functions you must be hitting it hard enough to cut both fuel and ignition. Your true solution is to stay under the limiter

Learn throttle control.

WERD!

Same thing happens to me especially with a new H/duty clutch as it does not "pop" out anymore.

Agree with the boys above. Less throttle or After Market computer

The R34 will happily bounce off the rev limiter all day.

It used to be a slow pop pop pop as it hit limiter and then dropped spark then picked up again, but now with the light flywheel, its like a machine gun!

Nice.

Could be coils if it starts happening before you get to the limiter - mine starts misfiring at around 4500, and I don't usually see more than that because it feels terrible.

I understand that the car isn't running properly, but why do you want it to bounce off the limiter? If you're accelerating, hitting the limiter is costing you time, if you're doing a burnout, backing off the throttle a fraction should make bugger-all difference to smoke output, and if you're trying to drift, hitting the limiter generally means that you either have no throttle control or you're doing it wrong.

Learn throttle control - your car will thank you for it, and you'll be a better, quicker driver.

its not that i bounce it off the limiter often, its just the satisfaction that it will run cleanly if need be. all these people are sayin learn throttle control, learn throttle control, when clearly its not about that, i must explain a little better, as SOON as it hit the limiter, no bouncing off it, even without WOT, it still does it, sometimes doesnt even need to hit limiter, it just goes BRRRRR, looses revs and power and sometimes backfires hard. always when its under load.

sorry to confuse the subject but yea im not one of these 'lets just flatten it around a corner' style drivers.

[RYanR31]

also, it wont stop bogging down until i let go of throttle, could go as low as idle if i wanted to..so does the fuel and spark limters bog it down that much? it would eventually pick up again if it was the limiters.

Hate to bring back such an old post but did you ever figure out what the issue was? My RB25 is doing the exact same thing and I can't seem to figure it out

[Manuel Kasko]

It's not missing is it?

That would explain why it happens in higher rpm and feels like it's bogging down. What sort of power are you making and what coils/plugs?

[johndanyal]

It's a completely stock rb25

[Manuel Kasko]

So the engine bay in your picture is not yours? Because that has a front mount intercooler which isn't stock..?

Only reason I ask is because the clearer picture we can make the more help we can be.

[johndanyal]

It's all stock except the intercooler.
