5.9 Magnum Dyno - Cam and Intake
Hey guys, thought you might find this interesting. Here's some dyno results for my 1998 Grand Cherokee 5.9.
1. Lowest curve is the baseline run (stock other than k/n intake and cat back)
2. Middle curve is after intake manifold swap and headers (converted an rpm airgap, basically making a hughes copy)
3. Highest curve is after swapping stock cam for a 222/226 0.545/0.555 110 LSA unit from hughes.
Although the total power isn't very high. The gains sure are noticeable. Engine has 201k miles and runs so sweet. I've probably made over 60 dyno pulls on this poor thing and it just loves it.
Next step will be heads. Maybe some day they'll be some good ones in stock somewhere...
