[supra2800turbo]

Hey

I was wondering... Today when I was out crusing with a friend, looking at some girls etc , I saw this corolla which had a 1.6 twincam with modded cams etc - it was wild.. .I barely could keep up with it.. anyway... I noticed that when I hit 4-4500 rpm, it feels like I have a power loss of somekind - specially in 2nd and 3rd. How come? Im running 6 PSI on the CT26 and with FPR + adjustable RRFPR.

Is it the CT26 which cant keep up at that rpm, or am I short on fuel (running lean) ? theres no knocking... nothing I can hear at least...

you might be leaning out or the timing is not right

Install a wideband O2 sensor so that you know what the combustion is doing.... and check your timing or might as well buy a BTM so that at least lessen the cause of detonation....

Its worth paying a few dollars than blowing up an engine....

I just thought that, if I was leaning out, then it at least should give me some knocking sound.... but it doesnt.

My timing is set to 10 BTDC.

not really.... there is a point of leaning out that you wont even hear a knocking sound.... check it very well before running it again hard

hmm okay ... I'll stay below 4000 rpm's for now... and I have it dynoed in a few months -- now I first has to rebuild my brakes......
