Considering Buying.....

[nismo280]

Here's my plan... currently I own a Nissan Maxima, and a F-350 P/U. I love both cars, but its time for a change... Anyway... I'm considering selling those two, and buying a Windsor powered GT, 1994-95. The stock 215 HP just aint gonna do it for me, so I budgeted a supercharger. I was wondering if a supercharger of 6-8 psi could be simply bolted on, with the natural fuel system mods, etc. Can the stock heads, intake manifold, and exhaust system handle it? Who makes the best, or "safest" supercharger?... Ford Racing, Paxton, Powerdyne, or Vortech? Have many people done this?.. Would I benifit alot more by replacing the heads, and intake? Should I consider an intercooler?... I'm not a full time racer, however... I'd take it to the track a couple times! or... should I go modular?...


Thanks so much, I appriciate all replys...

Vortech has a kit for the 94-95 5.0L that puts out 309 HP on a stock car. I believe the kit comes with everything you need to run your car.

Thanks

Would I benifit much more by replacing the stock intake and heads with ford motorsports equipment? Would the short block handle it.

With 6-8 psi, yes. I would recommend that you change to hi flow heads, intake, Throttle body, MAF, pick a good custom grind cam and upgrade your fuel system.

what would it take to get into the mid-high 11's what to most GTs with the T-5 trans come with as far as diff ratios?... would 4.10's help, or would I power through the gears too quickly?

So far, I'm looking to:

-Vortech Supercharger
-Ford Racing Cam (E303)
-BBK 75mm Throttle Body
-Ford Racing Intake manifold kit & inlet adaptor
-GT40 "p" heads
-MSD
-Fuel system upgrades, pump, filter, pressure regulator


where will this put me?


appriciate the help,

11.5's..... hummmm You realize that Civics with 2.2 liter engines are running 11.5's and getting 20+ MPG??????

I would stroke the 5.0 to 347 cubic inches, run the Trick Flow R type heads and one of their matching roller camshafts. You can expect about 575 horsepower at 6,500 RPM and you will be playing with 10 second quarter miles after if you take the time to get the chassis set up properly.

Vortec stuff is awesome. But remember that the heads are where the rubber meats the road. The TFS R head mounted to a 427 stroker 351 W produced 641 HP on GAS ALONE. You might consider this for the newer Mustang chassis since you are trying to move 3,600 lbs down the quarter mile. A 5.0 will get you 12's but a 351 W might push you to the 11's.

You can plan to spend about 3,000 dollars for a supercharger system, and you will have to bolt that up. After paying the cold hard cash, it will still not run as fast as a prepared engine running the TFS R heads.

I saw a 5.0 last night with an E-Cam, 3.73 gears and T-5 run 12.25 ET's and brag about how fast it was. Minutes later a 1.7 liter RX-7 with twin turbochargers ran a 10.95 et on gasoline. With Nitrous boost this car would be toying with 10.4's or faster.

I am telling you right now that a blower is not necessarily the best way to roll. It simply shifts your problems into a more difficult to solve arena. Do you have access to a dyno? Do you have an unlimited budget and patience to deal with shops that claim to know how to do the work but only know how to wrench on some bolt on items.

A nicely built 351W with long rods, TFS R heads, a street/strip roller cam, and 5 speed with 3.90 to 4.10 gear should get you somewhere near the low 11['s. It will be fairly simple to add a NOS fogger system at under 700.00 dollars should you want to run it in the high 10's.

Spend your money wisely, and remember there are Honda Civics and VW Beetles running 9's with less than 2,500 CC engines.

It is solid engineering that gets you the speed. A supercharger alone is just a tool to up your horsepower. But are you married to the dyno tech? If not you will be running low to mid 12's thinking you are fast. STUDY BEFORE YOU SPEND!

[nismo280]

Exactly, I'm researching before I spend. I have access to a dyno, and an awsome street/strip techie... Another concern is that I live in an emissions controlled area. I'm sure a clean burning 351 would pass, but a heavily modified one?... uhh.. I dont want to put money into something that I cant drive. I know about the damned imports running low numbers, hell this guy I work with drives a 10 second del slow. It drives me crazy, but there are american street machines running low 9s... take my dad for example. (He's a chev. freak, but my heart shall stay with the Fords )

I'm just tired of all this trash talk I get about fords, so I decided I must put them in their place with a fast mustang. If a stock 302 can handle nearly 600hp, why not build off that? I really like 351w, thats what I had in my truck. oh well, back to the drawing boards...

Hey Tony don't get down about the Rice Rockets. Look what money they spend just to get to 10 second times. With that kind of money I would be running a Ford Engine to 7 second quarter miles.

If you will be emission controlled, go with the 351 W block. You will need a long rod kit and a vortec blower. The long rod kit will help keep you from detonating. It will also give you unbelievable torque. Make sure the kit you choose understands your desire to add the supercharger.

Go vortec because it is basically a crank driven turbocharger. The centrifugal design means it pushes more boost as the RPM get higher, so at normal street use, you are getting better mileage.

Run the T5 till it breaks, then go to a Tremec or a Richmond 6 speed.

Run 4.10 gears, 4.30's if you want an extra tenth off the ETs.

Run a low pressure unit on the steet. When you race, you can go with a high boost pulley but run the 100 octane race fuel with the high boost. You should be able to hit low 11's without too much concern, and you will be emission legal. The TFS R heads are race only pieces. They will NEVER pass an emission test.
