Having fun with an LS1 intake and power tools. ;) Derek @ MMS was nice enough to let me borrow a couple old LS1 intake manifolds and some porting tools to play around with. My focus isn't to "port" an LS1 intake per say, rather to reshape the port inside the intake for more high end power.
I discovered that you can easily cut a 1.5" wide x 3" deep slot at the bottom of each intake runner (basically cutting the bottom of the runner off) and wind up with a dual plane style runner. You get a 2" runner on the bottom plane the stock 13" runner on the top plane.
In addition I'm going to drill out the large support bars in the middle of the intake for a little more top end flow.
The best part of this is that if it works, its a really easy procedure. You don't have to cut the intake in half and glue it back together or anything like that. I'll post some pics tonight.

Re: Having fun with an LS1 intake and power tools. ;) It came out pretty neat. <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> I'm hoping I can get some dyno time tommorow or Saturday at MMS to test it out.

Re: Having fun with an LS1 intake and power tools. ;) Nice try, Terry. Good to see people venture out into the unknown in search of gains in creative ways. The real question is, if you saw real gains, would you share with us or would you quietly sell off your LS6 intake? J/K <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />
Re: Having fun with an LS1 intake and power tools. ;) hmm, i guess gm did know what they were doing making these intakes <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> though i admit i would have tried the same if i had the opportunity
Re: Having fun with an LS1 intake and power tools. ;) With our past experiments with modifying the LS6 intake,everything we did lost airflow\HP potential. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />
The only thing that helped was smoothing out the casting flash on the inlet floor.GM desigined the intake on the edge of turblence,and everything made it worse.
