1996-98 4V COBRA MODS

[@GroovesAndLands]

I had a 98 Cobra back in the day. Mine had the 1.5L non intercooled Kenne Bell blower and IMRC deletes when I bought. I modded my manifold for short runners and raised the manifold floor like "they" said to do. Admittedly, I did a bit nicer job than shown here, but I could still feel a significant torque loss - with no commensurate gain up top to show for it. Luckily, I had 4.10 gears which kinda made it a moot point on street tires. I used to bleed ford blue back in the day. Now I'm with Richard - I just like good running engines, whatever the source...

[@midnight347]

A properly done ported short runner Def performs better but you need a gear to take advantage some shorten them too much and it kills their power curve. Nasvt knows how to do his ported short runners.

[@drgibs347]

Uhh theres endless aftermarket support for the ford modular engines.... pretty much anything mustang has the largest aftermarket support.

[@andyharman3022]

@@drgibs347 Only because for 25 years, the Modular was Ford's only production V8. Ford really missed the direction of the market when they designed the Mod engine. The wanted it to be small enough to fit in front wheel drive cars, so they designed it with 100 mm bore spacing, pretty much limiting it to 93mm bore. Meanwhile, GM and Chrysler have the LS and Hemi that can go to 104mm bore. The Ford just can't compete with the 2-valve version, so a 4-valve dohc engine is necessary. Expensive to manufacture. Expensive to modify.

[@madmod]

@@andyharman3022 The bore was selected to make the engine square and keep displacement down. It makes for a more efficient combo overall being less prone to detonation with the small bore and good stock heads. The long stroke helps with cylinder filling especially with the 2vs which focus more on port velocity than flow, hence why even the earliest 2v out torques a lot of pushrod engines. Richards own test saw 260hp- 341ft/lbs run with the stock npi cam and intake vs 250hp-300ft/lbs out of the 5.0 combo. It's obvious the modular is effective at power production despite being quite small in displacement. You can't argue it missed the market when the 2v outsold the other pony cars and still competed with the 70ci larger, and more powerful combos where the 4v was much more suited. I'm tired of the claims of how spendy they are because I have been able to source running 4v c headed combos for under 300$ for years. These stock heads and cams will support almost any power level you'd like to reach on a 281.

[@andyharman3022]

@@madmod How much does a set of cams for a 4v Mod cost versus one cam for an LS or Hemi? That was my point, and don't try to tell me there is no difference in cost. As for all of your other statements about the Mod, it's just cheap rationalization from a Ford fanboy. "Long stroke improves cylinder filling." That's a laugh. The 2v mod outsold the GM F-body because it went out of production in 2002 for eight years. I ran my Camaro in about 100 track days from 2002 to 2016, and was never passed by a Mustang. From my point of view, the 4.6 was no match for the GM 5.7.

[@Milehighsnake98]

Typically these engines can live long lives with a safe tune at about 450-475whp. At least that's been the history with the potentially thousands of boosted ones running around. With a 15% loss, that 450whp would be about 530 crank hp (and would actually read even higher than this test because this has the electric water pump and appears to not use an alternator (not 100%, but that's what it looked like in the picture @4:30).

[@KarzKreated]

The 4V gurus have perfected the Short Runner Intake. It's best to only cut a couple inches off the runner length. Also keeping the bellmouth ends is beneficial. Lastly, raising the floor of the manifold the same amount that you take away from the runners will help keep the torque from dropping off. Unfortunately, the B Heads have limited support for aftermarket intakes.

[@GroovesAndLands]

Not saying another short runner manifold wouldn't maybe do a little better, but this is basic helmholtz tuning stuff we've seen over and over and over again. Also, the "bellmouths" in those runners are as-cast and very poorly made. They don't hurt, but they don't work miracles, either. Last, I don't see how raising the manifold floor with epoxy is going to fix deficiencies in runner length.

[@bumsoil]

@@GroovesAndLands I have a modified intake made by NASVT. It's got about one and a half inches cut off, and the bell mouths welded back on. It's got a raised floor, and a few other tricks. It's 100% worth it if it's made correctly.

[@midnight347]

@@bumsoil ye they def make more power up top and won't sacrifice everywhere else nearly as bad as this video if done correctly. A short runner needs to rev its best to combine it with cams and rev to above 7k for best results. Nasvt really knows his stuff with these older 4v cars.

[@kevinjohnson9372]

I'd like to see a Lincoln mark viii engine basically it's the same block and heads but the internals aren't as strong but they handle 12to 15 pounds of boost. Cams are said to be the same but the intake and exhaust manifolds are more restrictive that would be a good starting point for a new test and then do cobra intake and headers then re degree the stock cam then splice part of this video in wear u added cams intake then blower

[@kennethpowers8995]

Most of the internals are the same as the Cobra with the exception of the crank; cast in the Lincoln and Forged in the Cobra. Pistons and rods are the same between early cobra and Lincoln. Block is the same, Tekskid aluminum block from good old Italy. Head castings are the same between early cobra and Lincoln except the cams are timed a little different; similar duration but Cobra gets more lift. Intake manifold on the Lincoln was tuned for low end and had IMRC to aid that low speed power. It was after all a nearly 2 ton Lincoln. Also there isn’t anything really a boost level the engine will handle. Like any engine it’s power that breaks parts, it doesn’t care at what boost level the power occurs. I can run 25 psi on a stock 2v if it’s through a small, less efficient turbo and only makes me 500Hp. At the same time I could grenade that exact motor at 10psi with a larger turbo that flows much more air. This is why it’s important to look at your compressor maps before picking out a turbo for your build.

[@kennethpowers8995]

I should add the Cobra intake had IMRC too as Richard said but it’s more of a CMCV system because it’s still a single runner intake. The early Lincoln had true IMRC which had a vacuum operated servo and a true 2 runner intake design. Cobra and later Lincoln 1 runner intake were electronic servo controlled.

[@Wear-N-Tear]

Were the cams degree’d ? Or just swapped out? Good gains with cams!

[@mrelectron6220]

Moises L most people do not degree cams and leave free HP on the table I've read this more than once from professional engine builders of the 4.6 2V and 4V. If each cam is out even one or two degree you have an imbalance and one side of the motor is fighting the other side. This is especially important on multi cam engines more so the single cam push rod motors. The worst you wind up with on a push rod motor is a power band that has shifted either up or down the rpm range a bit.

[@richardholdener1727]

these were degreed-mod motors can have cam timing off by a lot even from the factory

[@orange1soda]

Where can i get a short runner intake.

[@BA-pz3lo]

is there a similar video like this but about the 2001 4 valve?

[@samisdfosko1320]

It is quite interesting to see 96-98 Cobra motors with Kenne Bell hp per psi : So as default 96-98NA makes 305hp and with Kenne Bell at 7psi makes about 410HP based on their website, so math says: (410HP - 305HP) = 105HP. Which we divide with psi, so we get 105HP/7psi = 15HP/psi. Now with Richard Test: Modified NA = 376HP KB 8.8 psi = 485hp KB 11.9 psi = 506hp (485hp - 376hp) = 109hp. == 109hp / 8.8psi = 12.3hp/psi (506hp - 376hp) = 130hp == 130hp / 11.9psi = 10.9hp/psi So HP/PSI ration goes down very rapidly more you increast boost.

[@Milehighsnake98]

For one, this was a KB non-intercooled setup. The more you compress air, the more heat is generated. So using non-intercooled, you will see a decrease in returns. If you use an intercooled setup like a centrifugal or turbo, it will be more consistent that for X amount of boost, you would add Y amount of hp.

Amazing. Do you have part number for long tube headers.

[@richardholdener1727]

I think they were from Hooker

[@jason6175]

Interesting that the 4v 4.6l ford makes very similar power to a chevy 4.8l

[@midnight347]

And it's an older engine too as well as slightly less displacement. The c head 4c can do like 375 rwhp which is well over 400 hp on an engine dyno prob 450 and they can do that with just fbo, ported stock intake and cams. Pretty good for a 20 year old 4.6.

I'd like to see a Kenne bell flowzilla and blowzilla on the foxbody 5.0 shootout

[@thefinalgrind]

I just want to know the minimum mods I would need to run a turbo on my Lincoln Aviator to haul the kids around between long street lights..... fresh engine with 6k miles on it.

[@richardholdener1727]

just injectors and pump-then turbo and intercooler

[@kevingray7917]

Is the Kenny Bell affordable for the average person

[@christophercrowley6707]

You need to do 4.6 DOHC Turbo Intake options. How much stock 01 cobra intake vs ported vs Sullivan single plane with adapter vs a eaton/kb lower with a welded box upper with tb adapter

[@richardholdener1727]

did you watch the 4.6L 4V or the 5.4l 4V intake videos-same under boost-kzbin.info/www/bejne/nZ-5nquPd8t1pac

Whats the difference in the 96-98 cobra motor and the 99? I see root/screw style superchargers for the 96-98 motor but cant find any kits for the 99, they’re all centrifugal

[@richardholdener1727]

Kenne bell has blower kit for the 99-the heads and intake are different on the later Cobras (B heads vs C heads)

[@rustyretired]

@@richardholdener1727 the only ones i see on kenne bell are for the 99 2v, do you have a link for it or something? Thx

[@qward2174]

​@@rustyretiredHey I was trying to send you a link as to why KB discontinued the 99-01 4v kit but youtube keeps deleting the link. Type in "what happened to the Kenne Bell supercharger kit for 99-01 cobras" and you should get your answer 😎👍🐍💨💨💨💨

Was that a direct bolt in? Motor mounts match?

That’s exactly what I got going now. Stuck deciding whether to do it or go coyote

[@MZUNIGA012]

Does anybody know whats a good plug and play replacement engine for this? I have a 97 cobra which got a bent rod i want to take my time on building it but i want a engine that i can use to drive for now? Thanks in adv

[@richardholdener1727]

use a 2V bottom end with your 4v top end

[@ranware2779]

Find a mark viii engine and swap everything over

[@utahcountypicazospage5412]

Richard you should of left the cut manifold with nitrous to have nitrous give back torque and rev it to 8000

[@ab-cd456]

Didn't Ford get class action sued by owners over the power output of these motors? As in lack thereof? Maybe that was the 1999 model.

[@coreybell9525]

why does the curves always cross at 5250 rpm on gas engines?

[@richardholdener1727]

hp = tq x rpm/5252-just math

Will this same kenne bell supercharger also fit on a 1999 mustang cobra

No-the lower manifold is design for the dual-port 96-98 4V heads

If you would really like to have your own boss intake, I could help

Put forged pistons and rods and twin turbo it and make some serious power.

For 1996-98 Cobras, if your throttle cable ever breaks, good luck finding another one or even one that will cross over!!!

agreed, freaking 200$ just for a used one on ebay.
