Kevin.pk Posted August 31, 2008 Share Posted August 31, 2008 I posted this in my project page but i'd like to get some additional input. I searched and didn't really see anyone with a super victor intake under the stock hood. I thought I'd share that it does fit. My car is using the JTR mounts and jtr frame spacers. Super victor intake #2925 The real limitation is the air cleaner that will fit. I am currently using a Mr gasket filter part# 1486. I am actually just using the filter directly on the carb without the base plate. Its a 6.5" filter with ~5.25" inner diameter. It is 1.5" tall. Clearance to the hood is ~.25" with filter installed Here is a picture of the filter installed: (sorry for crappy cell phone picture) The real question is how much do you think a filter of this size is restricting? Would I see much of a power increase from a larger filter etc. I think I read an article in car craft that did a comparison of filters and the conclusion was that the size didn't really effect horsepower by more than 2-4 if any. With that said, this filter is slightly smaller than any of the ones tested and is also not the k&n brand that they tested. I am currently debating on whether or not the cost of changing to a larger filter is worth the added expense of either a cowl induction hood or a scoop added on my current fiberglass hood. Thought and comments appreciated, Kevin Quote Link to comment Share on other sites More sharing options...
HarrisonTX Posted August 31, 2008 Share Posted August 31, 2008 I wonder if they make a drop base bottom 5.25... I havnt seen one. I wonder if a drop base 14'' would work for you. i dont know, because it would extend about 5 inches further towards the front of the car, as well as drop down... http://cgi.ebay.com/ebaymotors/AIR-CLEANER-14-DROP-BASE-5-1-8-CARB-FLANGE-K-N_W0QQitemZ110282726133QQcmdZViewItem?hash=item110282726133&_trkparms=39%3A1|65%3A1|240%3A1318&_trksid=p4506.c0.m245 Quote Link to comment Share on other sites More sharing options...
Kevin.pk Posted September 1, 2008 Author Share Posted September 1, 2008 the Carb has a 5 1/8" opening. The filter is slightly larger on the inside but seals to the top of the carb fine. I actually tried a drop base already and it does put the tallest point too far forward and it hits the hood considerably. I think I might have tried that with a 4" tall filter though. Either way with the 1.25" drop base and the 4" filter, it held the hood up about 2 inches if I remember right. Might be able to get a 2 filter with the same drop base on it... not sure. An oval filter may work, but it wouldn't be much larger than what i currently have. The downward slope in the hood is killing me.

bjhines Posted September 7, 2008 Share Posted September 7, 2008 You can get a short 14" round filter element from Summit or Jegs. I think 1",2",3",4" are all available. http://store.summitracing.com/partdetail.asp?autofilter=1&part=SUM%2D239317&N=700+4294925239+4294925170+4294925169+4294891681+4294744163+4294791516+4294791303+115&autoview=sku or MrGasket part #1480A http://store.summitracing.com/partdetail.asp?autofilter=1&part=MRG%2D1480A&N=700+4294925239+4294925170+4294925169+4294891681+4294744163+4294791516+4294791303+115&autoview=sku K&N offers an open top filter lid in a 14" dia. That should allow plenty of airflow into the carby. You have to consider that the choke horn will come very close to the aicleaner lid. That will cause the air to make a very tight 90degree turn and obstruct flow to the primaries. For this reason I would suggest an open top element like the K&N one.

grumpyvette Posted September 7, 2008 Share Posted September 7, 2008 ID POINT OUT that your NOT limited to the standard round air cleaners, and that this is another case where owning a decent welder, or careful shopping for less comon air cleaner designs makes the solutution very simple. the first place I generally look is here http://www.ramairbox.com/kits.html http://www.ramairbox.com/models.html http://www.knfilters.com/Racing/customcarb.htm but theres NO reason you can,t fabricate a custom air/box with a remote filter location or visit a salvage yard and get the vast majority of the parts for a remote air filter location set up from a EFI equiped car and connect it to an air/box on the carb with 4" tubeing Quote Link to comment Share on other sites More sharing options...
91_4x4runner Posted September 7, 2008 Share Posted September 7, 2008 Disclaimer: I don't know anything... Don't they say that a longer intake increases net torque? Or at least an airbox setup... Quote Link to comment Share on other sites More sharing options...

I think your just a bit confused, a longer intake runner in th e intake manifold, between the head and plenum,( PROVIDED the cam and compression MATCH tends to increase torque) not the intake air filter length track Quote Link to comment Share on other sites More sharing options...

I do have access to a welder and such. I have just been going back and forth as to whether I feel like doing the glass work on the hood to mold in a scoop or /cut/weld/fabricate. Basically I need to get off my @$$ and just do something. Thanks you for the links. It definitely opens some options up. The current filter is absolutely a temporary solution as to get the car on the road. I knew y'all would have some good ideas. Kevin Quote Link to comment Share on other sites More sharing options...
rustorbust Posted September 8, 2008 Share Posted September 8, 2008 If you say that you have 2.5" as it is now than you should definently be able to run this base......http://store.summitracing.com/partdetail.asp?autofilter=1&part=PRO%2D66808&N=700+4294925239+4294839057+4294755992+4294756359+4294739245+4294745026+115&autoview=sku.... with like a 3 inch filter and have no clearance problems. And it will flow alot more air than that small filter you have now. James Quote Link to comment Share on other sites More sharing options...

And it will flow alot more air than that small filter you have now. James Well as far as I can tell I have about ~2" of clearance from the front of carb flange. The issue I run into is that the hood really starts to slope around the area in front of the carb. The other issue I have is if I change to a drop base like that, I may have to change my throttle setup as well as move the pressure regulator/gauge on the passenger side of the carb. I'll try and reach up from underneath the car to take a pic to show the clearance i have and hopefully that will shed some light on the situation. Its looking more and more like I am gonna have to fab something up or find something like grumpy said about an remote air filter set up from a efi car. Or at least that is what I am currently leaning towards at this point. Kevin Quote Link to comment Share on other sites More sharing options...
jbk240z Posted September 8, 2008 Share Posted September 8, 2008 You might try a small column of clay or playdough about 4" or 5" long. Put it on the front of the carb/ air cleaner flsnge pointing up. Close hood fully but softly. Open hood and measure the unsmashed clay and there is your clearance. Good luck. Quote Link to comment Share on other sites More sharing options...
grumpyvette Posted September 8, 2008 Share Posted September 8, 2008 many of the current efi cars & trucks have remote mount filter boxes with large rectangular drop in pleated replacement filters that can be mounted in several locations, its a basic no brainer to carefully measure and weld up an air box to bolt over the carb and run a 3" or 3.5", 4" connector hose between the two, with some careful thought the filter housing can be located where iot has dirrect access to cool air, and your not limited to locations dirrectly adjacent to the engine. salvage yards almost give those parts away, I doubt the cost will exceed $25 for the filter housing and a few other components if your creative and can fabricate... theres more options Quote Link to comment Share on other sites More sharing options...
FFMarc Posted September 10, 2008 Share Posted September 10, 2008 something like this I think would be cool.. http://store.summitracing.com/partdetail.asp?autofilter=1∂=SPE-252D&N=700+400068+115&autoview=sku Quote Link to comment Share on other sites More sharing options...
Administrators BRAAP Posted September 10, 2008 Administrators Share Posted September 10, 2008 Hmmm…. Using FFMarc’s induction idea pictured below, (pic courtesy of Summit Racing), mount it facing backwards and plumb it through the firewall into the upper cowl region with the filters under the cowl, (not sure how much room there is for that big of filter ?!?!) Cold air intake from the high pressure zone just under the windshield. Down side, (or upside depending on your point of view), is the induction noise, (WHAAAAHT) will be more audible in the cabin at WOT. Personally, I prefer to hear the induction noise over the exhaust noise. Sends chills down the spine. Quote Link to comment Share on other sites More sharing options...
spdkilz02 Posted September 10, 2008 Share Posted September 10, 2008 That would definately be a cool idea. I know that we sell alot of the spectre kits. Quote Link to comment Share on other sites More sharing options...

I wonder how tall it is. Now I have to decide if I need carpet more than I need this air intake setup. Decisions... decisions.... That at least give me an idea of something to fabricate as well.
