possibly, try it and let the rest of us know!

anyone have one for sale?

 

I am going to agree with MINES. I believe you are guessing.

 

with a test pipe total....25hp gain


My guess...

 

With testpipe, I say 20hp.

 

how high would my compression be if I do the spoon HG and shave the head a little? ideas?? Maybe even the cometics. Minimal thickness sold by cometics is .027 with bores of 89 & 90mm. What is stock thickness?

 

Deja vu?




I have no answers for you.

 

It depends on how much the head is milled...I can give you a better idea after my motor build. My head is going to get the least amount shaved off that it needs, probably only .001" I'm running 11.5:1 on the motor, I'm sure that milling the head will only change it by maybe .1 and definitly no more then .2

For you though, a spoon HG is said to raise compression by .2 and if milling the head .002" gave you .1-.2 well you'd be up .3 and probably no more then .4 so you'd go from 11.0:1 to around 11.3:1, probably only worth it if you are doing the majority of the labor.

A real way to find out is to find out how much thinner a spoon HG is then stock, and however many thousanths less it is how many thousanths must be milled to raise compression by .2 Now, you don't want to go to crazy because you might run into valve clearance issues if you do.

 

Or just buy the Spoon Hg =)

 

hehe, no. MAYBE just MAYBE if he super lucky and the honda gods allow it, 15hp maximum, but probobly not even that much. I feel I can say that having been down the same path. Ive seen this car lose 10hp from a fraction of a degree of too much cam advance or retard. Ive seen a piece of cardboard blocking the radiator make another 5-8hp. This engine is SUPER sensitive but you can make more power if you are smart and subtle about it. Understand you will not do it with bolt-ons alone. There are things going on in that magical cylinder head that take all your synapse firing on song and a fair chunk of $ to unleash, and you wont see any of it with "mad JDM tyte" parts.
