Alright my exhaust is 3" mandrel bent piping 3" carsound and a 3" magnaflow. Its not restrictive trust me.

I had it tuned but with some difficulty. The hondata stuff was acting up. We couldnt get the datalogging to work so we did the best we could getting the fuel right. I'll post up a dyno graph in a sec so you guys can see whats up.

Here is the dyno graph. Will tuning it better bring out 50-80 more horses?? Let me know what you think is the problem. Thanks

ok im not too sure, but 12.1 maybe a little rich on the fuel. maybe with your set-up 12.1 a/f ratio is safer, but just something to think about.

what is your timing set at??

Anyone else have opinions? What should I check? What would be a better a/f ratio to run?

OK people I know I should have more power. The only mods are whats listed. Those are the only ones that matter. Could something be wrong with my motor? It has 47K on it. It runs smooth and clean. No smoking or anything. Any ideas?

no cams, no gears? how do your spark plugs look? did you leave the ac on when you dynoed? lol lots of people go to the track over here and say they left their ac on, but then again they could be ashamed of their of time.

for the a/f ratio; try something around 13.1. any leaner might cause some problems.

also, what do you have for tuning aside from hondata??

good luck

Timing is whatever my tuner set it at. (not sure) My spark plugs look good.

NO my a/c was'nt on Click the image to open in full size. Click the image to open in full size. Click the image to open in full size.

I don't have different cams or cam gears.

I'm not sure what you are talking about when you ask "what do you have for tuning aside from hondata??" What else do I need???

You guys think if I lean out my a/f and advance the timing a bit I will pick up alot more horsepower?

Can someone post up a dyno sheet of a turbo b18b with similiar setup so I can compare. I'd like to see the difference in power curves.

Another thing people, I'm using the wastegate (tial) with I think a .45 bar spring in it to regulate boost. Its the silver Tial I received from Max-Rev. Could there be a problem with the wastegate? Why the hell is it pushing 10psi??? Or is that normal?
