JRSC DC5 Best Cam Angles help
Re: JRSC DC5 Best Cam Angles help
It seems right. With a stock exhaust system:
Low cam 40-45 @ 3000 rpm, dropping to 20 at 5000 rpm.
High cam 50 to 6500 rpm, dropping to 40 at 8000 rpm.
With a header you can run higher cam angles on the low cam.
Low cam 40-45 @ 3000 rpm, dropping to 20 at 5000 rpm.
High cam 50 to 6500 rpm, dropping to 40 at 8000 rpm.
With a header you can run higher cam angles on the low cam.
