what plugs are you running in the accord? also, what gap. there is a good chance thats your problem if the tune is good. the tune could also be your problem though.

the accord engine cant handle much more than 200whp on stock pistons. putting some h beam rods and forged pistons in there would let you get away with just about anything. the sleeves will pose a problem eventually, but considering the questions you are asking, i dont see you maxing them out anytime soon.

 

I don't know I was just reading somewhere about a n/a accord running over 300+ hp on stock internals. Thats not boosted, so I thought then maybe it was because of the detonation from to much compression with stock internals. I've read the f22a1 can not take over 12psi. So I kinda thought water/methanol injection could surpress detonation allowing more boost to be run to make over 200 hp at 12-16psi. It only has a base map tune. I have not had it tuned yet. I still need to put in the fuel pump before I get it tuned. I was hoping to go this week.

Anyways the plug gap is a little wide. I ment to gap it at 28 and I'm pretty sure I gaped it at 38. I had thought about that this morning. But have not got around to fixing it. But I bought new plugs. Ngk platinum lasers. The ones that are in are just ngk copper plugs. Just what stock calls for in heat range . I keep trying to find colder plugs but the auto parts stores are not helpful.

 

just ask for the bkr7e's. there realy isnt anything better for a boosted honda. stock plugs gapped to .038" could be your problem, but if its an untuned basemap, i would be leaning more towards that.

detonation is always an issue to be concerned with, but even with no detonation cylinder pressures can break ringlands. i would just see what kind of hp you can get from 10psi on the dyno and call it a day.

 

sorry it took so long. these are pics during assembly. I am running 12 pounds of boost.

 

Ill get upgraded pics soon. these are old and unfinished

 

Are you just gonna boost off the wastegate? WG dumptube, or just right there?

 

this pic is old. the exhaust is all done. ill get new ones today

 

12 pounds of boost

 

these are from today. I am now running 14 psi and it runs great on 93 octane. with my other base map. its running rich anyways. I actually found a local tuner. which is amazing. But I accidently cut the tendon to my right middle finger. so I am kinda laid up at the moment.
