Heath, saw on your site you are selling a lot of oil by pass systems, which system do you reccomend for a 99 dodge 24 valve with 265k making just under 500 hp on dyno?

 

Hey there, sorry it took so long to get back...camping weekend.
For the 1st gens, there are a couple options. You can either go with a single bypass filter mount that utilizes your existing full flow filter or you can go with a dual mount(both full flow and bypass on the same mount).
There's adv. and disadv. to each.
The single takes less space and is less expensive. It's easy to get the oil to the filter, but you have to find a place to return it.

The dual it bigger and therefore is installed most often on the frame somewhere. It does make it easy to change oil with both filters right there. The oil is received and returned with the adapter you screw on where your current filter is.

On my old 94 I went with the single and returned the oil to the oil pan. It worked.

ONe other thing that you might consider but SHOULDN"T be a factor is the dual is feeding both filters. IF in the event something went wrong with the filter or mount, with the single mount, you can unscrew the oil feed and put the plug back in and go back to running on your old system. I have never heard of this happening but I've always had it in the back of my head.

If more interest, let me know. I can send you install instructions to look at for both as well as pricing.
