you can do it yourself.....a dremel will do it....nothing fancy....just take care of mold flashing and do a port match....i spent 2 weeks doing my fast 92.....really needed it !!

 

 

Do you have a Mamo ported intake?

 

 

I was referring to what ( minor stuff ) you could do yourself....with a dremel.....what tony can do.....is another story

if you can afford tonys stuff ....go for it !

 

I do. Save your money.

 

Russell,

Thanks for posting that link for me. Its from 2010 (believe it or not) but the info posted there is just as relevant today and the pics clearly show the improvements from the porting (opening of certain cross sections of the runners) that allow a ported intake to significantly out perform an out of the box manifold.

All of the multi piece composite intakes (FAST, MSD etc.) are pretty rough in out of the box trim. If you have the time and inclination than doing some of the obvious blending with a dremel is very effective but if you want to get the most from the swap that's a different story entirely

Its really all about your goals and the budget for the project you are working on. I cringe at the thought of installing one of these multi piece composite intakes out of the box....they just leave too much airflow potential and performance on the table.

Another big issue never talked about that I have the opportunity to see over and over is the large difference in fitment issues in out of the box trim. Some intakes are worse than others as it is a stacking of tolerances and some luck (good or bad) when these intakes are friction welded together (its not an exacting type of process). That means some guys see more or less HP than others in unported trim but once properly ported, you remove that large variable regarding how the intake was originally constructed. In fact I have returned some brand new intake cores that were so misaligned I knew there would be a good chance I might grind a hole in one side of the port wall trying to open it up to where it really needed to go to work effectively.

"Experience" is everything in most industries but especially so in specialized processes such as this. For the guys smart enough to value you that commodity you know where to find me

Russell I look forward to working with you shortly on your MMS 220 project.....thanks for chiming in this thread on my behalf

Regards,
Tony

 

man you're really wasting your time with a dremel. Way to much material gets removed for one of those. I don't even own a dremel. They're pretty much useless. I love seeing guys do stuff themselves and learning tho. With that said you can turn these things to junk.

 

I did my fast 92 with a dremel AND a air grinder with cartridge rolls....takes a steady hand and a good eye for either tool.....I ended up with a pile of shavings as big as what tony gets.....I am no novice as I do motorcycle porting too.....if you don't feel comfortable with the tools do not attempt and turn a $$$ intake into a worthless pile of plastic

I think the 92 without porting is a missed opportunity as there is so much room for improvement......jus sayin

 

I use different size/shape carbide bits to rough in the shape i want then go to cartridge rolls/drum sanders to finish them off. All with air and slower speeds.

 

 

If the difference between the best porter around and the 2nd best porter is only 2 rwhp, I won't lose any sleep over it. The main question was answered here, porting an lsxRT is worth it.

10 extra rwhp from the 2nd best porter would be satisfying enough if that is the reality, on top of the gain from an unported lsxRT intake manifold (15-20 rwhp over a tbss intake? Just guessing and hoping).

I don't even like referring to the other porter as #2 as it's not a CNC job, so the "#2" ported may be the true #1 porter on a few intake manifolds that get more time spent. This isn't to say Tony Mamo is #1 and Doug ( HioSSilver ) is #2, it was just me saying that a 2 rwhp porting difference between the 2, in either direction, would probably not be noticeable at the track through my unlocked 3800 stalled th400.

Thanks guys for the do it yourself info but I felt more comfortable sending it out for porting. I do my own tuning and exhaust systems but send porting and diff related jobs out as I know what I'm good at and not good at haha.

 

 

Doug is the man!!

 

 

I'll be able to say the same soon, he's shipping out mine now 🎁🎂

 

 

yes. this man, wise he is.

 

Just wanted to see whom is doing the porting on the MSD Atomic and the FAST 102 LSXr intake manifolds. I'm building a 427 with a Lingenfelter GT21 camshaft. My LS7 heads have been CNC ported by Magnatron. They flow 395 cfm at .700 lift. Lingenfelter says that they have had great results with the MSD Atomic intake. I'm thinking a longer runner, like that of the FAST 102 would work better (ported, of course) than the MSD. For the porting gurus, which is easier to port and which one flows better overall? I'd most likely have it ported, professionally, by someone who knows what they are doing. Thanks in advance for any relevant and good input.

 

The consensus seems to be that if you will be spinning the engine to 7500 rpm and higher, go with the MSD. HioSSilver ports the Fast intakes as well as the MSD ones. He's in this thread so just find his username and private message him, he will accommodate your porting needs.
