Quench pads are nothing new. Ever looked at a GSR engine? Your timing theroy has little to do with those quench pads and more to do with the cam timing. Y8's aren't hard to tune either, so please don't give people this impression.

 

i thought it was 90 ft lbs of tq?

 

The quench pads in a D16y8 are nothing like what they are on a GSR. I also never said the vehicle was hard to tune. I said it was DIFFERENT than most other Honda engines and you can't assume them to be the same. A D16z6 can be tuned the same way as a B18b1, GSR, B16, h22, or f22 plus or minus vtak. D16y8's in standard OBD1 editors requires some end user knowledge to tune correctly.

 

resurface the head check timing and if you dont have a breathing system get one

 

Felpro shouldnt be used either. Stick with OEM or a Cometic or similar.

 

stick with oem only cometic gasket are no good ether we see them fail over and over oem is the best gasket you can run

 

Your statement was:

"y7/y8, have a lower base timing and have quench pads unlike any other Honda engine."

which is incorrect. You said nothing about how these pads were "different" then a GSR head. Care to explain to me how they are different? This should be interesting...


If it takes you 2 hours on the dyno to figure out the small difference in a Y8 then perhaps you shouldn't be tuning cars to begin with. I am using simple P30 inigition maps followed by a simple edit of the idle section on the low cam maps. Works perfectly fine, 0 issues. I don't see how the timing difference in these engines is anything special or why it would require the extensive amount of time to solve like you have stated. It sounds like you are stating what you have HEARD from others and not what you actually know for a fact to be true. Thats all I am saying...

 

Well I never checked back on this thread, but it was the radiator cap. Still boostin it daily and no problems with the fel pro gasket and apr headstuds.

 

70 is the rec. torque for arp mains and head studs.
