Dan & Jopey, You guys have done a great job on the intakes. I am very impressed. It would be fun to have a dyno'd comparison test. What would it take to use them on a dyno? High pressure pump, computer. During our "fire time" we have upgraded our dyno with a pair of wide band O2 sensors. And I still have the project engine as a possible mule motor.
Yes, I am running a carb type screw-in filter as a prefilter for the pump.
I was thinking of doing the same thing with a prefilter to the efi pump. but with a clear filter so I could see if it was clogging up. one of the ones you can just take apart, spray with some carb cleaner and air and reassemble.
My CHI intake is for a 351W deck height with CHI 3V raised port heads. I have adapters for a 400 deck height with CHI 3V heads. You would need custom made adapters to use it on Aussie heads. You would need a Pump and filter assy like mine. I used a Walbro GSL292, 255 LPH pump and an Earl's filter. You would need a regulator, mine is an Aeromotive Adjustible Regulator. Also an A9L computer, a 5.0 L harness, and a Tweecer to tune it.
While we are discussing custom made adapter plates, this thought has passed through my mind on several occasions.
Make a set of adapter plates for 2V heads and an Edelbrock RPM Air Gap Manifold, and machine injector seats into the adapter plates. Any 2V manifold could be used, and a throttle body could be mounted using a 'Power Elbow or the Sullivan Performance Cobra TB adapter.
That brings me to my next problem. The 460 upper intake will not fit on my motor. I knew that I had some height problem, and was prepared to have some height cut off the intake. However it is worse than I expected. The height is not that bad, but the 460 upper intake hits the cowl, and I cannot mount it on the manifold.
I have the option of turning the 460 upper 90 degrees, but I think that I will have a problem with the hood braces. I plan to check that out tomorrow. I will take some pictures and post them. This is plan 'B'.
Plan 'C' is to purchase the Sullivan Performance adapter.
man that's close. Obviously you've considered fabricating a piece (box-like) that you could insert into the cowling (after a cut-out) to keep it sealed and allow the extra space you need- but that must be a more difficult option than you have going.
Was wondering if i could get your build specs from you to include parts and scr/dcr, hp/trque from your ddyno etc??
Here is my build spec. It is a 400 (+0.030), Ohio flattop pistons(1.64 CH), CHI 3V heads (64cc), Crane Roller Rockers (1.7:1), hardened pushrods, guideplates, 5.0L replacement roller lifters, custom roller cam from Midway Cams (281/281 adv, 224/224@0.050, 0.595/0.595 lift), Comp Cams roller cam conversion kit(dogbones&spider), Melling HV oil pump, Cloyes true roller timing chain, Sanderson Headers. The ignition was a Mallory Unilite distributor, Mallory Promaster coil, Holley Annihilator ignition, the carb was an Edelbrock 750 CFM, and a Carter elctric fuel pump.
I am replacing the dist. with a ProComp TFI unit for a 351W, but with a 351C gear.
The EFI system will use 42# injectors, a 2003 Cobra TB, BBK cold air kit for a Ford Lightning, and a 90mm Ford Lightning MAF calibrated for 42# injectors. The Computer is an A9P from an '89 Mustang, as well as the harness. All of the sensors are stock Ford Mustang/Cobra/Lightning. The fuel pump is a Walbro GSL 292 (255 LPH).
The Static Compression Ratio is 10.1:1, and the DCR is 8.0:1.
The torque is 404 ft-lbs@2000 RPM, and peak 517 ft-lbs@4500 RPM. The Peak HP is 524@6000 RPM.
I am running an 1800 RPM stall converter.
If I were to build this today, it would have a forged crank, probably a stroker, some work done on the oiling system, and forged zero deck pistons. It runs great as it is, I hope that I can get the EFI setup running at least as well as the carb.
Here is the latest rendition. It consists of a 4.6 L Cobra Plenum from Sullivan Performance. This fits a lot better than the 460 upper intake.
I still have a few problems to work out. The F150 Lightning Cold Air kit from BBK will not work, because the TB is too far forward. I will still use the Lightning MAF and cone filter, but I will need to fabricate the tubing between the TB and the MAF. Since the TB is oval shaped, that will be a real trick. Maybe I can modify the BBK air section and add some 3.5" round tubing.
I'll be installing the harness as I work on the Air Section problem.
I bought AN-6 hose from Summit. I bought 20' of the Summit Brand. I have some left, but I think that I want to keep it for a while. I bought fancy Russel fittings, but Earl's are nice and a lot cheaper. I tore my fingers up putting those ends on that braded hose. By the time I got the knack for it, I was done.
Don,
Here is a link for Air Intake hoses. I think they are in your area. I will send them some photos, maybe they can supply the right pieces for my problem.
That's a good article on braided hose. I actually got pretty good at cutting it with a hacksaw. I chucked the hose in a bench vice, letting the piece that I needed hang out the right end of the vice. I steadied the piece with my left hand, and sawed with my right hand. I had to stand over the vice to do this. I sawed gently, so that the blade cut and didn't pull the braid apart. I found that the cut end away from the vice was cleaner that the cut end close to the vice. I made a few bad cuts until I was able to make consistant good cuts. I put the first fitting on the worst side of the cut, and the second fitting on the best side. I made a couple of lengths where the first fitting went on, but I couldn't get the second fitting on until I worked that out.
this is cool chit! Now I'm wondering why your cam, with a longer overlap and quite a bit more lift is only draining 2 pts off compression when my relatively rv'ish roller cam drains the same to a bit more?? Also, whats with the ohio pistons- I like the height..I take it theyre bushed clevelands? putting this thread to favotites for sure!
Ohio Piston & Pin were one of the original manufacturers of the flat top 400 pistons which were actually designed specifically to convert the 400 to propane.
