98 Mark SC Build

Hello everyone, may I just say this thread was my inspiration to join this forum! Amazing Mark you have sir. Someday I wish to put a KB on my '93 Mark.

Can't wait to see future updates!
 
Thanks, and Welcome SpyderDiablo and nismotunedgtr! :) The Cobra intake is going to be installed when Aric is ready to do it. Probably after SSHS7 though, as I suspect there are going to be a bunch of Big Fords coming to the ATL for SSHS7 wanting Aric's attention in the next month. The brakes and rims should be on the car though.

I will ask him if he will do a before and after Cobra intake dyno pull. With that new 3.1 pulley on there, I am very close to max for that stock bottom end already. He is going to put a boost gauge on it to see where it is at, but, his math puts the new pulley at 10-11 psi and 400-430rwhp.

You can really feel the difference with that new pulley & extra 50rwhp. :)

Aric thinks we might be able to get a set of Mustang 16" rims over the Big Ed extenders in the rear with some wide DR's for the track. He is going to check into it. More than likely, they will have to be made. I do not think Boze makes a 16" rim in my style, or I would probably suck it up and buy two more of them in 16" for the track.
 
Mike I have a set of 16" DR's mounted on a set of Chrome stock rims, if' it's meaningful to you I can make you a packadge deal.
 
Thanks, Charlie, but I already have a set of 16" DR's mounted on some stock OctaStars. I am having the hubs converted to Mustang 5 x 4.5, and that is where I am running into a problem. Along with the sway bar mods, I can now get a wider DR in there than the ones I already have.
 
With SSHS7 behind me now, and the Mark's new hubs, brakes, rims, and tires being installed in the next two weeks, it is time now to start thinking about fortifying the engine.

The car now has 401rwhp, and 318rwtq, and has run a 12.162 @ 113.42 in the quarter mile. All this on a totally stock engine with 107k miles on it with the help of the Vortech supercharger.

Aric is going to put down on paper, a quote to forge the bottom end, and refresh the heads. He has a bare block at the shop that he will use to build the forged engine from, and then swap over everything when he is done building the motor.

I am not going nuts with this engine at this time. In fact, 400rwhp is plenty already. My intent here is to make sure the engine is way safe for this kind of power and on up to 500rwhp if/when I ever decide to go that far. :)
 
Mike, get forged flat top pistons! Forget the low compression junk, ask Burbank 98 he is running 10.5 compression pistons and look how his car flys down the track.
 
Mike as mentioned above do not lower your compression. I too am running high compression flat tops. As a reference you can read up on it in SHM's book. We all know you will be stepping it up. I have no issues with what I am running and it is very safe.
 
Nice, another Vortech powered Mark VIII running great times.Like stated before don't go bellow -5cc on your forged pistons,I'm building forged Teksid now for my car and I'm going with these pistons.
 
Thanks Guys, the quote I am looking over is for a 302 stroker with custom Manley pistons-off set, race ported cylinder heads, and custom grind cams. :)

I wouldn't go with stroker for centrifugal blower application .Centi blowers love high rpms and by adding stroker you're lowering your rpm limits.

I'll second that. I bought Jeremi's 97 with a built engine. about 10:1 compression and 14 or so psi. It's great, I can still get about 22-23 highway MPG at 75!
 
The way it was explained to me, if I go with this engine, it will be much more efficient moving air through it ie: less boost needed to make the same amount of power I have now. It is about the whole package - intake, heads, cams, and pistons. Additionally, when you start making big power, high compression is not favorable. 9:1 was the number given to me. :)
 
when you start making big power said:
Are you planning to make big power 600+ rwhp or 20+psi of boost than go with low compression if not than go with higher compression because you should have no problems with detonation on Intercooled setup like yours.
Just look at the Difference between my setup high compression vs yours stock compression. I have similar bolt ons as you and last year with 3.5 pulley on my vortech (8 psi) and stock gen 2 intake manifold my car run 11.7 @ 120 mph and yours with 3.1 pulley is running 12.1 @ 113 so what is making my car stronger !!!!!!

High compression =more power with less boost

Yes. And beyond... :) The problem I am faced with, is deciding to go ahead with this motor and never actually use all the power potential it has. It is a motor designed for JT trim.
 
Do not comparee your motor to his. It's too close in compression. Stock is 9.85:1 or something vs your 10:1. The power comes from somewhere else and you know it ;)

The biggest difference is when people talk about mighty ford ill advised 8.5:1 vs 10:1 or so. The power curve and TQ curve look and FEEL enitrely different in that case. Ever dyno a stock 03 Cobra motor without the blower ? LOL

Mike likes his torqueless car. Leave him be. 9:1 sounds like a very good number for your plans Mike.
 
Finally decided. :) It was very tough, but I found myself at a crossroad with the Mark. I have decided to keep it in the 400-500rwhp range. I just do not see the point of going any further with the power at this time. Therefore, mostly bottom end stuff is going to be done. Here is a highlight list:

Injected 302 Stroker Kit

Custom Manley Pistons-off set

Manley H-Beam Rods

ARP 2000 Bolts

Total Seal Stainless File Rings

Federal Mogul H Rod & Main Bearings

ARP Main Stud Kit

ARP High Tensile Strength Head Studs (with 12 pt nuts)

Melling High Volume Oil Pump with Billet Gears

Refresh Cylinder Heads

Accufab Single Blade Throttle Body

96-98 Cobra Intake

Aric is going to use one of his Teksid blocks to build the motor, and swap with the motor in the Mark when he is done building the motor.
