    Thanks for the info, that's what I'm looking for!

    Can anyone identify these springs?

    Yes, I've seen that response on Google, however the numbers that Google references for the front springs are not exactly the same as the numbers I entered. They are close, but it refers to br33 vs br3v on my springs, and nothing matches the KB at the end, and those 2 digits make all the...

    Can anyone identify these springs?

    The front springs have part # br3v-5310-kb-e29ej on the tag wrapped around one of the coils, the rear springs show br33-5560-db-e29ej. When I search google I can't find anything referencing these precise part numbers. Some come close, but nothing exact. I bought them over 10 years ago to...

    Octane Booster!

    You're half right. The most efficient way to burn gas in an engine is at the highest pressure possible before detonation. Start the burn too soon and you get negative torque, meaning the pressure build up in the chamber is trying to the stop the piston from coming up in the compression stroke...

    Octane Booster!

    Actually, resisting ignition from a flame or spark and resisting ignition from pressure and heat with no spark are 2 different things. Octane is a rating of the latter, which means a higher octane fuel can take more pressure (and the resulting increase in temp) before it ignites. That's why you...

    Octane Booster!

    molar mass? do you mean molecular weight? If you're refering to molecular weight then I believe that is incorrect also. It comes down to what gas actually is at a molecular level and how its refined out of crude oil. The amount of energy contained in the gas is based on the carbon content...

    Octane Booster!

    That's just a retarded statement. Octane by itself has nothing to do with power. It also doesn't have anything to do with how clean or completely the fuel burns or how fast or slow it burns. "all else being the same", octane is nothing more than a rating of how a fuel resists detonation or...

    Ecoboost

    Last I heard they won't do an Eco V6 since the power is too close to the 5.0. They would only add that to the line up if the standard 5.0 output was upped quite a bit and that is cost prohibitive right now, but they are tossing aroung the idea of an EcoB 4 cyl and reviving the SVO model. That...

    Fuel mileage ?s.

    Oooooh, that explains why I always see mpg numbers higher than what I get, I thought everyone was stuck using E10 :dunce: If I could get real gas, with no ethanol in it, I'd probably be getting 28-30 hwy mpg too. As it is, I can squeak out 28 with my 4.0 if I turn off the a/c and set the...

    Ecoboost

    No, the Taurus is front wheel drive so the engine is mounted sideways. FWD engines use a different block casting with mounts and bellhousing bolts different from engines mounted for rear drive. However, the ecoboost in the F150 is mechanically the same as the FWD version ecoboost and it IS a...

    Picking up 2012 V6 Auto on thursday...tech question in last paragraph

    IMO, changing the oil at 1000 miles is a waste of money. As someone else pointed out, engines are run in at the factory these days. I'll concede that total ring seating may not be complete when the car arrives at the dealership, but I believe the rings are 90% there going out the factory door...

    Whats needed for a 5.0 swap?

    Sorry for reviving an old thread, but I was wondering if anyone has yet to successfully swap a 5.0 into a 05-09 car using a 2011/12 factory PCM and harness? I know a bunch of people have done the swap into SN95's and Foxes using the FRPP kits, but they present several problems for the S197 if...

    What is your MPG

    The best I've ever gotten was 28.5 hwy, all stock '09 with 87 octane and a/c turned off. I generally avg 20 city/ and 24-26 hwy depending on what MPH I set the cruise at. That's measuring mpg the old fashioned way too, I don't trust the electronic gadgets to be very accurate for mpg, they...

    05 - M-90 and Nitrous

    Just curious, what version of the M90 do you have? There are probably 100 different variations of that supercharger, not all of them would be good candidates for installing on a 4.6 3v. 2 or 3 of the most common versions are from different years of the GM 3800 and are pretty specific in their...

    Mustang motor and Trans in an F-150 pick up

    The 4.0 V6 would be a total custom install as it has nothing at all in common with 4.2 truck motor. It also doesn't offer anything performance wise to justify the trouble and expense that would be involved with such a swap. The 4.2 is a stroked version of the 3.8, with an intake manifold...

    longevity of stock springs

    That 130lbs is not from the engine, it's from all the other things the GT gets that's heavier than on the V6 car, i.e. thicker sway bars, larger wheels and tires, more standard equipment, etc. IIRC, even though both the V6 and GT use the 5R55 AT, the GT manual trans is beefier than the V6 manual...

    4.0 serpentine squeal - harmonic balencer?

    When you replaced the belt, did you get the one with the updated part number mentioned in the TSB? If you did and that didn't fix the squealing, check to see if any of the accessories have excessive drag, causing the belt to slip. A/C compressors can do that just before they fail. The crank...

    2011 Mustangs

    My 2 cents... IF you are in the market for a new 'stang anyway and aren't just looking to buy something with better mpg because of rising gas prices, AND you have the money to buy a GT, don't opt for the V6 just because it gets 2 more mpg (EPA rating 19 mpg city V6 vs 17 mpg city for the GT)...

    Anyone even mount the CS scoop rearward?

    It's a science I don't quite get just yet..... I know some cowl hoods feed air into the scoop, that was the 1st application of it that I know of and was used on the late 60's Camaro and Chevelle on their cowl induction hoods. The high pressure area at the base of the windshield forced air...

    Anyone even mount the CS scoop rearward?

    This may be a Mustang forum, but that T/A is a sweet looking ride, it was also the hottest car that everyone wanted when I was in high school so it will always be a favorite of mine :rock:

    Anyone even mount the CS scoop rearward?

    This is sort of the look I had in mind when I thought of this idea. That was a concern I had, but cowl induction scoops are placed within a few inches of the windhield to take advantage of that high pressure area, I was hoping the CS scoop was far enough forward of the windshield that it...

    Anyone even mount the CS scoop rearward?

    Anyone ever mount the CS scoop rearward? Just wondering if anyone has ever tried putting the factory Cal Special hood scoop on their car facing the windshield. I'm looking for a way to make a functional heat extractor on my hood, and I'd like it to have a subtle appearence as if it was done by...

    what you know about 302 to a 306ci???

    I got that info from a machinist who's been building Fords for over 20 years. Just because a lot of people share the same belief about something doesn't make it true. I had heard the same story about the Mexican blocks for years, but it was always from other people who (like me) had heard it...

    what you know about 302 to a 306ci???

    FYI, the Mexican blocks are not higher nickel, they were desirable in the 70's-80's because they were the only 302 block to have thicker main bearing caps, similar to the 289 Hi-Po blocks. They looked beefier, so most people considered them to be stronger, but many machine shops (at least in...
