Side draft intake on a 6.7 - Competition Diesel.Com

bigsexy7.3 · 08-17-2017, 11:50 AM

I'm in the process of building a new motor and having a head gone thru for it. As far as head goes is worth the cost to have a side draft done? I'm currently doing bigger valves and port and polish. With the stock motor I was putting 900hp 1900ftlbs in the dyno and my new goals are 1200 on fuel and 1500 give or take on spray. What benefits have guys seen with side drafts?

I would like to know myself I have made 1200+ on the stock intake with a mild ported headed I wonder what all else it helps also

I have heard of problem with side drafts pushing open the valves on 3&4 because the air is rushing to one area of the head. The intake plenum by D&J that Lavon uses helps distribute the air along the entire head first before going into the valves. I am not an expert this is just what I have heard.

One benefit is you can port the intake side of head.

Looks like I'm going with the side draft. Next project will be figuring out how to mount the fuel plate and other things
