    98 gt + full throttle = coolant leak?

    The PI intake is the intake from a 99 and up Mustang GT. It flows much better than the early intakes and is good for a 10 hp gain. Many have swapped to this intake, I have not because I have a SVO suercharger. Use the search function to find what is needed to perform the swap. From what I...

    98 gt + full throttle = coolant leak?

    Sounds like the intale is cracked alright. The not quite recall does not apply to the 98 year model. A Get a PI intake and search around Corral for what is needed to do the swap several people have performed the swap and all are happy. Dwayne

    Tire pressure for street racing??

    OK first I'm gonna say take it to the track. Second street tires need to be at the normal operating pressure to ensure full contact patch with the road. Do a short burn out and look at the patch it leaves. It should be as wide as the tread face narrower indicates too high pressure with no...

From what I can see inside the oil fill the inside of the engine is very clean with no sign of varnish and 0 sludge. I have been supercharged for the past...

    Mods for a 96 4.6

    Install a pair of PI cams and a PI intake manifold. This will give you at least 20 hp. If you shop around you could pick them up for around $200. Learn how to drive your combo and effectivly use the power available before you go dropping loads of money on stuff you don't need. Also there are...

    To All Those 96-98 Gt Owners!

    PI CAMS SVO/ROUSH Supercharger with a 3.4" pulley. You will be right at 300 rwhp and more TQ than you can use. All of the other stuff is not going to give you much and will add up to a ton of wasted money. Dwayne

    Chassis stiffening questions...

    Also to stiffen up the stock K member I installed the lower K brace from a vert into my coup. It just bolts in and ties the K together in 6 places AND out to the rocker panels. This provides much needed strength to the front end. I got mine from a junk yard for $50. Dwayne

    need info on a eaon supercharger

    Even though the Eaton is a very reliable and quiet unit it will not fit because the Cobra uses 4 valve heads and the GT uses 2 valve heads. It is not possible to interchange intakes between the two unless you also change the heads. Dwayne

    Help with squeeky belt, it's embarrassing

    Get a smaller belt. look at the tensioner there are 2 marks on it. When they are ligned up you have the correct belt installed. With a belt too long you are probably getting a lot of belt slip also which is going to cost you power. Dwayne

    roots/centrifugal style blowers on a 4.6 SOHC vs. heads/cam/intak mani.

    I am going to have to agree with J98GT. For 2 grand and a stock 97 motor the best way to go for reliable daily driven car the SVO/Roush blower is the best way to go. Just by installing PI cams and using the 3.3" pulley he will be at the 300 hp mark and a butt load of low end TQ. The TQ will give...

    Lugnut torque specs?

    100 lbs ft. is standard for the 1/2" Ford studs/nuts. It makes no difference if you're using steel or alloy wheels. With alloy wheels recheck the tq after a couple of days just to make sure. I have had them loosen on me and even lost a nut cause I forgot to re check them and yes I always use a...

    Is belt dust normal with an RR pulley?

    You have already stated the belt you put on was longer. It is probably too long and slipping. Put a shorter belt on there and you will eliminate the dust. Dwayne

    Howoften should I change my synthetic oil?

    I have a 96 GT that I bought from new. I installed synthetics at 1000 miles and have changed it 1 time per year from then on. I do a filter change at 6 months and top off the oil. I use 1 quart of oil per year + the 1/2 qt to replace what I loose with the filter change. From what I can see in...
