From Bone Stock to ....

I am pretty familiar with how to extract N/A horsepower from the DOHC engine, as my self-tuned bolt-on Cobra puts out in excess of 300 RWHP.

Here are my plans for my "new" LSC, comments please.

1. Ported 98 Cobra Intake Manifold, I own an extra one.
2. Underdrive Crank Pulley, again I've got one in stock.
3. Headers, I haven't decided yet between a set of JBA Cobra Shorties that I currently have on my Cobra, or a new set of Kooks.
4. Stainless Steel Mandrel Bent Exhaust w/Hi-Flow Metal Matrix Cats. I recently fabbed one up for my SC.
5. SCT Tune, hopefully a starter tune from Lonnie, then I'll tweak it with my Pro Racer Package. I own an FJO WB02 setup.
6. Either a "J" Mod or plate from Lonnie
7. Deep Trans Pan
8. Good Trans Cooler
9. 4" Aluminum Driveshaft
10. 4.10 gears. I've got a new Cobra pumpkin in my garage that I set up for my Cobra (going from 4.56's to 4.10's as I add an intercooled vortech and forged short-block this winter) with a Tru-Trac diff in it.
11. Focus Fuel Pump, again in stock.
12. SN-95 Bolt Circle Change
13. Brembo Calipers / Cobra rotors / 98 Cobra Wheels

What's everyone think, am I on the right track? Should get me in the mid 13's, I would guess. My SC weighs 3990 lbs. with me in it, puts out about the same RWHP as the Cobra, and runs low 13's with 3.08 gears, but it's a 5 speed.

Well looks like you forgot to list the wheels you will use.

I don't know if 4.10s make sense when you have a supercharger... but for NA purposes they do.

I'll be using a set of '98 Cobra wheels, as on my SC.

The 4.10's make sense for an SC in my Cobra, NA I use 4.56's.
 
You left out the most important mod - need to put a torque converter on the top of your list. :)

SCP sells Kooks made for this car. People will tell you it is a waste of $ for the net results though. I would do it if you plan to go FI down the road. Do the headers and exhaust at the same time to save some more $.

Marks hit the scales with driver around 4000 pounds. If you want a decent 60', no less than 410's and a 3600 stall tc should get you around 1.9 - 2.1.

I was going to try it first without the TC, just to see what the results were, but I'm sure that you're right. My SC weighs about the same and 60's between high 1.8's and low 1.9's. I've never raced with an automatic before, it should be interesting ;)

I don't think I'll ever go FI on the LSC, but that's the plan for my Cobra this winter (parts in stock).

I've already seen what even 1 5/8" Shorty JBA headers and a good 2 1/2" exhaust did for my Cobra NA, so that will be the minimum mod for the LSC.

I do all my own work, even the exhaust, so all the $$ will go towards parts.
 
Stall converter is what I was going to say too. I don't know about 1-3. Or what #12 even is. :)

But I'm confused, so double check, I really thought the 98's didn't need the j-mod.

And I don't know if it would improve your times, but one thing I really want to get are bigger front and rear swaybars.

#12 is changing the F/R wheel hubs to Mustang Cobra parts so I could use Cobra Wheels and larger brakes. Here's a link to my article on the subject.

Thanks, I'll double-check on the "J" Mod.

Larger bars are a great suggestion. I have them on my SC, so I guess I would have realized it sooner or later, thanks.

Ahhh, OK thanks. I haven't done a brake upgrade. Then again, my car's pretty tame. I do have the 2 1/2" mandrel bent exhaust and LOVE it. I have some high performance mufflers on my car and the package alone gave me something like 2-5 tenths at the track (hard to say, didn't get a lot of runs). Then again, I have a base model.

I'm with the others on recommending the torque converter.

Don't let anyone tell you headers aren't worth it, even if they are simple 3/4 lengths. If you're doing the intake, you're leaving a lot on the table without headers. The two go hand in hand IMHO and it sounds like you know from experience.

Just don't be suprised when the combo that works well on the Cobra or SC disappoints you on the Mark VIII. Without some suspension braces, it will suprise me if you get sub 2.0 sixty foot times. With 2.0+ sixty foots it will be tough to get 13s, let alone mid 13s.

Don't forget you're handicapped working with a Gen2. :p

Handicapped because of the stock intake and tune, or are you just busting my chops?

Suspension braces? Please explain further.

I intend to make delrin bushings for the LCA and Spindle, as I'm currently installing in my SC.
 
Oh they think the 2nd gens are slower than the first gen's, but we've proven them wrong time and time again. ;)

I broke 15's with my Mark stock. So there!

2 things with the 2nd gens, the ECU detunes the car when it shifts so it was smother, a tune can take care of that. And a lot of 2nd gens had the LSC 10 spoke chrome wheels, the heaviest factory wheel, the fast 1st gen guys had the snowflakes, the lightest wheel.
 
Well, my LSC has Octastars, which I'll probably sell to pay for some of this :D and the 98 Cobra wheels are amongst the lightest that Ford ever sold.

I'm just bustin' your chops. I'm sure with the intake and tune, you'll take care of the Gen2 fallacies.

The rear IRS can be beefed up with a pinion brace, rear cover brace, torsion brace, rear shock tower brace and rear subframe connectors. The delrin bushings will surely help even more. The front subframe can be helped with braces as well. Of course, all that added weight will need some HP to compensate for it.

Good luck with the planned mods. It'll be interesting to see what you can do with it. ;)
 
Yeah, I'm pretty familiar with all the chassis mods, most are on my SC. Delrin LCA bushings in the IRS in my Cobra was the single best suspension mod I've ever made. It cut over .2 from my 1/4 times. I'm hoping for similar results in my SC, if so, then I'll put some in the LSC.

We're talking more than just changing bushings out. He is refering to the Braceing kits and sub-frame tying. SCP sells most all of it. Rear subframes you need to do on your own, which is pretty straight forward.
