Went along to Triple H today in Irvine to put my EK9 on the dyno and a get a compression test done. The Dyno is a Sportdyno V3.5. Compression was good at 225 on all 4 cylinders so I was happy!
For the figures on the Dyno I wasnt expecting much as my spec is just:
Stock B16B
2.5" exhaust system
B18 airbox with custom 63mm cold air feed
Spoon 4-2-1 manifold
NGK blue leads
Mfactory 4.9 FD
Mfactory Lightwieight flywheel
I was expecting maybe 170bhp at the flywheel as my car is 12-13 yrs old now and 108k miles so I thought it may have lost a few ponies! It gets regular oil changes and I look after it very well and its had a good thrash free life since I have had it the last 2 years anyway. it doesnt burn any oil too!
It weilded 147whp/177.6bhp and 116.3ft lb torque. I was happy but as you can see on the graph and from what Henry says my car is running way too rich at 11.6 I think and he said it should be 14.6ish. I dont understand all these numbers etc as I am no expert. He says it could be my valve stem seals needing changed or because of the crazy angle my exhaust has at the backbox causing too much back pressure. He said he was expecting atleast 195bhp from my set up! So I am pretty disappointed at the moment and trying to decide what to do?
Can anyone help? shed any light on why it may be running rich? give me some tips, etc?
