19103, compression test today after 700 miles since rebuild Posted by jamesman, Apr-04-02 05:53 PM
well i changed my plugs, and did a compression test while they were out. All cylinders are reading 220 psi, does this sound right for 1. compression? well, they are damn better than the 130 i was getting before the rebuild. lates james

god damn... 220 James. that is like a brand new car.
How does 10.5:1 feel at 8psi?
WE need to go Honda hunting one of these days with Mike...:P

yep 220 is great compression. That's like really high. I guess good compression ranges from 170-220 on a 420A. But 220 is really high, you running 10.5:1? Thats sounds bout right.
haha the best I could push out was 150 today :( the engine probably cooled down a bit though so who knows...

I wanna come Honduh hunting! I can keep up the smoke screen in the back of the pack, Spy Hunter style... confuse the cops :)
Whoohoo 120 on cyl 4, and another quart of oil kicked out into the engine bay on my way to work today ;) (arg)
Seriously tho, I wanna come watch. Still haven't even met u, james.

well, we run like 9.6:1 stock, and decent compression is ~160-220... with 10.5:1 compression, i would think that you would see higher compression #s..
im no engine guru tho, but i think im on the right page

correct. with 10.5:1 comp, your compression numbers should be higher than the same engine w/ 9.6:1, so u look to be in GREAT shape.

He has 8:6 compression from what I remember.

I gots 10.5:1 compression pistons, i have 220 on all cylinders. hey dave you get that email? is it understandable?. Nope haven't met you yet dan, aren't you like right near me here in cerritos, i was at road race one day and i saw a white eclipse in there getting an hrc kit put in and i was poking around and shootin the shit, and it happens that that was your car from what kaiser tells me. I think...well, i'll probably go to the next local socal 2gnt meet whenever it is an we'll all hook up. lates james

Yeah I have the diagram and it looks pretty good. I am going to do surgery on my type S BOV tomorrow. Should be fun. I hope it works and then it will be sounding and working much better. For some reason I thought you had low compression pistons. 10:5 should be pretty interesting. Let us know how it runs after the break in. I bet you cant wait to get on it.

That compression sounds perfect. I have 10.6:1 compression, and I had 220's in all four cylinders too. Most 2gnt's seem to be around 180's stock.

Marcus you have 10.6:1 compression also?
I know you had some pretty slow 1/4 times, what were they? I can't believe an auto with higher compression and headwork would still not break 16's. I have an auto too, I know the feeling.
