Working on it.
With rbc 33 with ips 22Great numbers!!
Do you recall the cam angles past 8K w/ the RBC and smaller t/body?
Funny you mention that because the head combustion chamber is 55cc comparied to factory 50.5cc which lowers my compression. So because of this my compression is not true 12.5 it is somewhere in the 10.4 to 10.0 range maybe even lower.When I do compression test it only reads 175 across the board I did leak down test and motor is still in good shape. So I took my head off and we took a mold and I sent to get custom pistons made. But this is what I am working with for now untill my pistons come in.Nice power for 12:5 compression~!:up:
Good cylinder head,tuner and the whole set up is working well together.i dont get it, how are you making that much power on that compression?
You could be right I am not to sure about exact compression 12.5 with a 55cc combustion chamber but 11.5 compression should make at least 190+ with a compression tester and I read 175 across the board and the motor is fine during leak down test.shouldn't your compression be around 11.5 with a 55cc combustion chamber.
that head has some good work done to it
good numbers by the way :up:
Intake valves are 1mm oversized exhaust are stock sizedThat mani made power everywhere, im sure the extra midrange is nice...
Nice addition to the setup!
Are the valves stock sized?
Are you serious knock it off already. Why don't you sell you k swap and get a single cam to match your civic.I already said the same thing.. Skunk2 manifold to match the rest of the engine set-up..
Stop stressing manifold alreadyWhen you sell yours to match your civic...:hammer::hammer:
Gee thanks manifold is working for me. But not as excited as when your single lobe cams came in.I hate to answer for him , but he seems happier than a *** with a bag of dicks.
it's a nice manifold but not for ppl like me.
I use what works. I tiped tuner I told him don't eat egg salad if he plans on riding the bus.Great choice in parts. How did you come to that choice in parts, research?
I hope you tiped the tuner.
The VTC was 36 degrees and is now down to 21 degrees up top with this manifold.My fuel pump was shot so at 8500 rpm the fuel pressure went from 60psi all the way down to 20psi thats why you see drop in power after 8500 rpm af ratio was around 13.0 and at 8500 shot up to 16.0 so we stopped tuning did not want to damage anything. I changed pump but have not had a chance to go back. I need to back to finish tuning.We did not tune anything below 5000 rpm when I go back I will and I will see were vtec cross over will end up. This car is a daily driver.Looks good. that VTEC point looks nasty. Thought about moving it lower? This is probably a drag motor so I'm guessing no. Ever thought about running the K10s? From the dynos I've seen the K10s don't show as sharp a falloff in power after 8k+. The first dyno I saw of the K10s with the IPS manifold held power to 10k rpm. :wow: Any idea what you could change besides the cams to extend the powerband into higher rpm?
How did the cam angles change once you got the IPS manifold on?
EkShould be interesting to see what the setup can do on a full tune...
What kind of chassis is it in?
Intake 235Jeff, do you have any idea what valve relief your pistons have on the intake side?
