Ported intakes

-
pick up Vizards intake manifolds book. He got a stock Q-jet intake to flow better "than anything available..." not my words, his. But if you want to drop $1500 on porting work on a Low deck M1, I think your polishing a turd when you can get a custom SM one fabricated and flowed for $2000 out the door!

That name sounds familiar, I think I'm following him on FB actually. Facebook has become pretty useful in the past couple years for networking with car and engine builders but you have to be careful because there's like 1000x more BS to slog through than even forums to find the legit people who actually know what they're doing.

Again, I don't want to ruffle feathers--actually IDGAF because that's what's wrong with the world these days is people "biting their tongues other wise known as being PC" --Be careful looking at flow numbers--there is something wrong with his bench and I have mentioned it to him in the past. His numbers @ low lifts do not JIVE whatsoever. Also to get back to the topic in this thread--porting manifolds. Porting a manifold is FAR more difficult and time consuming. To do it right the manifold really needs to be cut up and welded back together. The good news here is that most manifolds and applications do NOT warrant actual porting. In fact if the manifold is selected and applied properly--hold on to your hats for this---Porting will often produce less power and result in slower acceleration ie.- slower ET's at the track. IMO porting a manifold is warranted when the manifold is grossly undersized (wrong) or it is on a Nth level build looking for that last few HP. J.Rob

Agree 1000%. Find something else to spend your money on. I guarantee at the level of the vast majority of enthusiasts operate at money spent on porting an intake can give more value (better results) in terms of power by being spent somewhere else. Port match it. Maybe blend the plenum on a SP. Otherwise leave it alone.

Man sometimes I just don't understand your thinking. Do you race or is this all DYNO testing. Cheese and rice if you aren't seeing ET increases at the track after porting an intake you better lay down the grinder. Give me a break.

Ok I gotta ask..... Cheese and Rice?
 
Didn't mean to start a great debate by recommending Larry. I wish I could tell you how much I gained, but my trip to the track last Friday was a wash. I screwed up the only two runs I got.
I am extremely happy with the work he did, from the feel of the car on the street. I won't quote what I paid, but I feel like I got a lot for the money. RAMM, I fully respect your opinion, as well as Moper's, but I am still happy. Don't worry about ruining my day one bit.

When Ryan @Shady Dell ported my W2s I asked about intake porting and his response was it might gain me 15 hp... I am sure that gain number would be dependant on the specific application.
That being said I did port match and blend the plenum of the NOS Victor I got. It turned out the manifold runners were a bit mis aligned from drivers to pass sides so it was a good thing I did the port matching.
 
I see Jim Laroy's ( IQ 52) name has been dropped in this thread. Maybe he will chime in, I'm sure he has some useful information on manifold porting. I think he should be back from chasing elk. Hopefully he got one. I didn't.

Actually I misquoted, meaning to say RAMM. Sorry bout that.
Not to say it wouldn't be interesting to hear an opinion from IQ52.

Lets not talk about elk season.....urghhh
I did limit out on 16oz BPRs though.
 
Sorry I need to clarify, my intake was only port-matched by Toth... I got it second- hand because it was a good deal, I just wanted an RPM manifold for cheaper than brand new

I feel my intake, reworked by me, w/ a little guidance from an expert, is a step in the right direction. It took the runner scatter from over 40 to around 25 cfm diff., and raised it around 30ish cfm.
Definitly needs a taller manifold tho, it`s still a choke point for my heads.

I am just giving what I see as friendly $$$ saving advice. Your stuff runs 9's which is what I would consider a serious looking for that last bump in HP build--You also posess a flowbench as do I. Most of the world doesn't. When a customer asks me for intake porting and I quote him $1200-$1500 for a cut and weld job-most decline. I've also done it for EMC testing and often the AVG power gain is nil or negative.

I'll give you a break--put me on ignore so you don't see my posts. J.Rob

When I stopped porting for others I was charging 150-200.00 to port intake manifolds. That included flow testing bolted to their heads. Yes I have seen before and after testing done on the track where it counts and never had a customer that wasn't pleased with the results. I didn't cut them apart and unless it was an intake like the LD340 there wasn't a location on the intake I couldn't work on. In most cases with the intake bolted in place on the head and flow tested I would see a 3-10 cfm loss (max) instead of upwards of 40 plus cfm on some intakes. I used to enjoy cranking up my favorite CD in the shop and sitting there porting. Now not so much but I hope to again in the near future.

Cheese and Rice? lol.
From my perspective...
I'm not a track racer. I did spend years with a Stock Eliminator racer for a mentor. A racer that Ford gave a car to, multiple class records over decades, yada yada yada. He owns his own bench and an home shop that makes many pro shops look half-assed (or call it "burger and fries" in the Great Lakes area lingo? lol ). He spent thousands on tenths. It's his passion and he is successful in about 50% of his experimentations. The fun is the personal pursuit for him. The trophies the recognition by the rest of the world. I'd imagine a like yourself from what I've read on the sites over the years. I have tremendous respect for people like you.
That being said - I am a street racer. A learn-by-doing street rat and I will say very successful "in my day". Success in that area needs the same drive and commitment, but in many cases (at least in mine) the value is what matters most. If you spend $1, you need to gain that performance. One simply doesn't spend $100 without getting something for it. From that perspective - intake manifold porting is simply not enough return on the investment. Not paying a pro, not paying Hughes(who I don't consider a specialist in this area), not buying a bench to static test. I'm not saying there's not improvement possible. I'm saying the best result you might get (assuming the racer actually is good enough to notice such a gain with their package) is not worth the cost. The BEST ain't worth it. So realizing any gain isn't worth it to me. Given the participants on this board, I think I'm in the majority here.
 
I have been toying with the idea of having a manifold ported. I would consider my combination one of the “if I can pick up 10-15 hp” it would be worth quite a bit to me. I have a spare stock 68-69 340 intake, I’m just not sure it would be better than my current home ported intake with the divider cut down and the transitions rounded, its also port matched. Add to that most people don’t really do that much stock casting porting anymore. $1300 is a lot for Wilson to basically send me the same manifold I’m currently running with the “t” junctions cleaned up.
 
FS - in every case the individual would need to talk to Wilson to see what could be done and potential increases. I don't call 1hp/1$ spent worth any effort. But IIRC you race FAST and similar class restricted packages it might be more worth while. Call and ask them. IMO it prob worth extrude honing first and see it that helps. If it does it could point to potential gains from high end porting.
