2001 Cherokee 4.0
CR from 8.8:1 to 9.5:1
Mild custom cam
Mild port work
Relocated intake air temp sensor to air box tube
Muffler bypass (bypasses factory muffler when intake vacuum goes away, then through a cherry bomb)
Just drove it to town for the second time. It runs smooth but thus far I'm underwhelmed. Not the kind of throttle response and power I was expecting. Some say I should try bigger injectors and throttle body. And reprogram the ECU. I'm probably close to the point where I need the injectors.
Did not get a chance to really monitor O2 sensor data, the little I tried, it did not seem to lean out under moderate acceleration.
Still have some minor things to finish.
The Nova 230 project has not made any progress, it runs ok, I drive it once in a while, but next steps would be HEI and adapting a 2bbl on a stock intake. Need to make an adapter, I have a spare intake/exhaust manifold to work with.
That engine too seems less powerful than expected, but some of it comes from the single barrel bottleneck, as well as stock torque converter.
