Im looking into building my head for some higher revs. Im curious as to what is possible with the stock pumps. Are their any mods i can do to improve them? Where does the Y8 pump lack?

is 8,500 or higher reasonible?

 

bump

 

what pump are you talking about in a cylinder head?

 

not in the head, im talking about the oil pump. whether or not it can keep up with the high revs

 

the y8 oil pump was the worst oil pump that ever went into a honda, go with a z6/a6 or get one from endyne

 

i have a z6, will it support say 9k rpms?

also what can i do about my dipstick?

 

what about your dipstick?

here's the link to the oil pump, it says higher rpms, pm earl and ask him

Y8 dipstick is on/goes through the oil pump. Z6 pump doesnt have a spot like that for it.

Anyone know what those pumps have done to them?

 

look around on the site, he tell you exactly whats done to the lil pumps and why

 

yea, that didnt help much. anyone else have info?

 

1. Never give credibility to anyone who mentions Endyne or posts a link to their site/products.

2. Raising the powerband essentially depends on two things - the cam and intake manifold. It's possible to make power up to 8,500. Is it practical? Well, no. The point of a D16 isn't higher revs, it's higher torque at lower revs. If you keep pushing for a higher powerband, you're going to loose all your low end and overall output will decline.

3. There is nothing wrong with the y8 oil pump. This has been discussed a million times on this board - oil pump failure is related to harmonics and vibration. Realistically, with a good cam, a ported head, and a short-runner intake manifold, you'll make power to about 8,200. The oil pump will handle that no problem if you (a) make sure you have a fully balanced rotating assembly and (b) for extra protection, use a fluidamper.

 

what is a fluidamper, never heard of one.

so 8200 is realistic with appropiate headwork?

 

it's not the failure of the oil pump, The y8 doesnot give enought flow. not enough oil
=spun bearing(s). the pasage ways are smaller.

he asked about an oil pump, i gave him an oil pump, what do you have against endyne?
I feel the same way except with people who mention full-race

You are absolutly right on the damper.

 

what could you have against full race? what the hell is the damper?

 

a damper take the place of you drive puly,
