Just saw this, might be a cool deal for somebody.

ive always been a fan of the 8 stack look, but its not very practical with so many intakes that make big power now days.

[D-CEL]

The current crop of manifolds is certainly great. But nothing beats these when it comes to flow and their HP potential. Complex and expensive yes, but they offer almost no flow restrictions and with different stack lengths offer tune-ability that cant be had in any other intake system.

Admittedly, I’ve never seen a side by side power comparison, would be cool to watch.

What do most guys use for an air cleaner when they have stack injection or Webers??

Most every picture I see of someone's engine bay shows them with the mesh screens at best, which will keep out small animals but certainty not engine killing dust and dirt. I can't see spending $15K or more on an engine and then not running good filters.

[D-CEL]

There are several options. Individual air filters are common in the Cobra world. I have also seen “air box” style with a large square filter, dropped base and lid.

heres some pics of a nice setup, not sure where I even got thsi from (somewhere on this site I'm sure).

ive done side by side comparisons and the 8 stack doesnt come close, but im a mod motor guy, on a pushrod motor im sure its great, dohc is another story, not very good

Why? Can you please elaborate...
I know nothing on this topic and need the education...

Thanks,

Just hard to tune, mod motors are so plug and play basically a reflash will yield good gains. my intake for instance has runners that open and close at different rpm to aid in low end torque something dohc motors lack, so eliminating my intake would negate these gains. The 8 stack just looks so cool so 60's. Its just not modern technology for the dohc motor. So you have to choose between long and short runners, which can take alot of testing

Thanks... I agree, love the look of an 8 stack

Take a look at my pix if you want to see a real Kinsler "8 stack". Mechanical FI. no electronics, which didn't come in until about 1985 or so and worked. The early Kinsler was a copy of the Lucas/McKay system with mechanical distribution of the fuel into tall stacks. BIG torque, very snappy throttle response. Seriously sucks fuel, though, particularly with 8 Liters plus.
Nice item for a sbf, though.

fordracing65,
Well they look the best but that is subjective.
You have done a side by side comparison? That’s cool. Can you post your data? Sounds like it would be interesting to read.
Intake manifolds are compromise items. You can have one that makes good low end TQ but its high rpm power will suffer and visa versa.
I worked on a sprint car and a drag boat for several years and my experience was that Mech FI (constant flow) set-ups out-powered the carb deals. The top tubes (Bells), length, diameter and taper can be changed to make the highest tq and hp within the engines desired rpm range. I’m using the Kinsler/EFI SCJ on my big motor. If I thought I could make more power with something else, Id get it. Tuning an EFI IR system in no different from any other.
The manifold (looks like a version of the FR500 manifold) on your motor is essentially an IR manifold, fed from a common plenum and a single throttle body with secondary butterflies to help low and mid range tq. I really like the 4v mod motors. I have a 96 Cobra with a Vortech blown and aftercooled 4v 4.6 and a second motor on a stand in the shop.

The Lucas “timed” metering system was miles ahead of a constant flow systems (back before EFI was an option) from a drivability standpoint. That’s why the Can-Am guy ran them. Lucas (the “Prince of Darkness” company) built the metering parts and injectors (driven by the cam via the distributor normally) that you would fit to your manifold. From what I know, the MacKay (Brian Mackay) manifold was a copy of the early Crower manifold but specifically modified for the Lucas parts.

My motor is a fr500 motor. thanks. Like is said im only dealing with mod motors. Sean Hyland runs a 4.6 with an 8 stack never made it to production the flow numbers wern't as good as the fr500 intake or a fix runner design as used in grand am, he has all the flow numbers in his site. Your 96 has irc charge plates completly diff from that setup, if you remove those you will actually make more power, there is a reason the 8 stack isnt a common mod on the mod motor, mpg, i can get 27 miles to the gallon, aint happining with an 8 stack I dont care how good you tune it.

sweet car and sweet color, a cobra always looks cool on a dyno

[What'saCobra?]

Here is a shot of a mechanical Lucas/McKay SBC (sorry!), with the more modern use of high injectors for better mixing and straight-shot intake pipes.

7 liter SBC, broad peak of 730 hp @ 7000, 650 torque @ 5000. But, more importantly, over 600 ft.lb. from 4400 to 6400 (!) and over 700 hp from 5700 to 7500 rpm! This is an iron block SBC, stroked to 7 liters with cup internals, of course. Cost ten years ago? $47K

There was no need to run this engine above 7500 in a race, but if the track was big, like Daytona, i would not hesitate to spin this to 8000 in high gear straights if needed to win the race.

But, EFI Kinsler for sale here is actually much better to tune and set-up, once the engine is sensored-up and you are along the learning curve a bit. The mechanical Kinsler does stay in tune, even better than the Webers, of course. i would imagine the same for an EFI setup but have no hands-on experience.

[fordracing65]

that stack is not fitting under any cobra hood, looks neat though

[razerwire]

No bids? Would seem like street rodder would use this for visual effect.

Awesome stacks at a great price

I have found the 8-stack to be very easy to adjust. Think of infinite jets. I have been driving with my laptop in the passanger seat and made changes at different points (rpm, load, temp, A/F ratio), it is very simple and only took 20 minutes. You are right you might not get absolute HP but you will have more torque and a flatter curve due to the CFM capability. I also think it is a personal opinion on what you feel more comfortable with, I can play with carbs but I can tune EFI.

Here are some other air cleaner options:







...I'm pretty happy with my results.

The Kinsler kids went to high school in my area. So I went over to pick up a friend and one of the kids was standing next to my friend getting ready to show him something. He opens the door of his locker and there is a full 8 stack sitting side ways. It was brand new.

I stood there for several minutes looking before I felt a tug...to leave.

damn cool even back then.
