Cobra intake then supercharger, or just supercharger?

Here's that Crown Victoria with that SST twin turbo

This will add 120 hp to the Mark. To go with the twin turbo system you need forged internals.

Of course. It gives you the element of surprise. It hasn't been don in a Mark.

See any contradictions here? You have no idea what this will add to a Mark and cant use a Crown Vics 2V as a comparison.

As for tune, I could write a tune in a couple hours for it, thats easy.

The hard part is the fact IT WILL NOT FIT. I have ben over this with Sapperfire many times and layed under the car trying to figure out how to do it. Cant do it without cutting up the floor and firewall.
The Mark barley has enough room to run both exhaust pipes under the car and now you want to run a 3" pipe back from the rear to the front with your air charge. OK, simple enough, some custom piping with uber tight tolerences, a mandrel bender and someone who is a bad ass welder..... just might get that pipe back up front. Problem is now that its up front there is no way to get it back into the engine compartment. The exhaust pipes took up the only hole between the motor and firewall. So what you say? Gonna run the pipe under the k-member like the Vette does? Yeah, no. Take a good look at that k-member and all its scratches from hitting crap. Cant hang a 3" pipe below that. Then on top of all that your air charge pipe just ran for 8' next to an exhaust pipe so now your air temp is over 250*, intercooler is gonna have a hard time exchanging that much heat all the time.


Sorry guys, its just not viable on our cars.

That video was actually a 4V DOHC that was in that Crown Vict. As for me, I am not going to rule it out until I do some test fitting. I know this isn't a Mark, but where there's a will, there's a way.

OK GMAN, $500 says there is now way in hell you will be able to run the charge pipe to the motor. The gauntlet has been thrown.

I'm not going to get into a philosophical discussion with you Bill, but at the same time, I am not going to accept that it can't be done just on a say so without trying for myself, and doing my own investigation. It may not be easy or cheap. I know nobody here has done it or probably has the means to do it. Doing a STS system is something I would love to do, but is not on the top of my list of things to do. It is a route I may take in the future if I go that route.

The only way it can be done is to do a single turbo, Y the exhast together under/next to the trans, single feed to the turbo and single return then notch the floor and firewall back about 2.5" then run the intake tube over the valve cover to feed the intercooler and back to the plenum. And that would require a few inch cowl hood.

Greg, I aint saying cant to it just for the sake of saying it. I took off splash shields and exhaust and measured and discussed flat pipe with a couple companies and measured some more and removed crap to see if any more room could be made..... it just wasnt an option for our cars chasis and engine.

Now you could fit a single turbo in front of the motor and flip the manifolds around. Just have to relocate the oil filter, remove the oil cooling jacket, move the power steering pump over and delete the AC but that seemed a bit much too.

Our frame rails are just too shallow and floor pan has too many dips to make piping a remote turbo a reality.
Of course you could run the pipe inside the car and just deal with a buldge on the passenger floor but ya still need a cowl hood to get it up front if you still wanted the heat and AC to work.

I've done the legwork on trying to get a remote mount setup on a Mark, and now I have a P1SC I'm rebuilding. I wouldn't say it's impossible, but remote mount turbocharging is not practical on a Mark VIII.

Do not centrifugal supercharge

I will start this out by saying that every man has different epiphany's in his life, one of mine happened last night. I was behind a G6 GXP when he suddenly took off. I mashed it and tried to catch up. It took a few seconds to stop his pull, but I never could close the gap. Did some searching and saw that the 3.6 ones seems to be doing in the 14.2 range stock and with minor bolt ons are doing 13's.
I live in an area where there are more fast cars than not. I see Porsche 911's, M5's, Z06 Vettes, GT500's etc. daily and have accepted that I can not play with them, but a damn 4 door Pontiac G6? And now Mustang V6's are running times stock that our cars hope to do modded. My old Fox body Mustang was relatively quick running a best in the 12.6 range at 108 but had no where near the comfort or sophistication that my Gen II has. I was happy with the 4.10's and t-lok for a while, a short while, but I miss having a faster car. After thinking of selling the Mark for a generic (faster) car I realized that I would not be happy. Part of why I like my Mark is not driving the same car that every other peon is driving.
I have decided to find a used centrifugal supercharger kit and begin my quest for respectable times. The engine has 88,000 miles and I figure it should be able to handle 6-8 PSI on a safe tune without committing suicide.
I know the cost will be relatively high but will have around a 6K budget after selling a few toys. That should at least get the kit, injectors, tune, tranny cooler, J-mod etc. and get me on the road. I already have IMRC delete plates in the closet. Forged internal parts and greater boost can come later when additional funds are saved.
After all of this blathering on, my question is should I install the Cobra intake and then get a blower or sell the Cobra intake to help fund the blower purchase and install? My search turns up split opinions on the subject. The cons of the Cobra intake install (which I have) are that I would have to struggle to retain EGR function (I live in an emissions testing area) and the general hassle of fabricating a few things to work. The pro seems to be future expandability should I decide at a later date to get more serious with it. If it was your car with the aforementioned budget restraints, what would you do? At this point I am leaning toward selling the intake off to fund the purchase but I am not set in stone.

I have a 98 Mark w/Vortech, 350 easy RWHP but it has to rev to get boost, install a KB or other positive displacement sc for instant boost to get all that weight moving. Mine has a 98 Cobra kit-9lbs reached at exactly 6500 RPM
