Hello, After 18 years and 106,000 miles about 85% of that at the 600 RWHP level with a basic 2.3 Whipple setup, my mint 03 Street driven 03 Cobra has an internal engine knock. Being an old man with slow reflexes whom seldom runs the car more than moderately up thru the gears, being careless ...

Continental Extreme Contact DW 285/40-18 rear, 255/45/17 front for a bit over $800 I went with narrower fronts to avoid traming in the crappy NH back roads I drive on and to give the rims some protection with a little higher profile sidewall. Continental Extreme Contact DWS06 are...

It has been so long since I've done anything but oil changes to my Cobra I'm either lucky or neglectful. ( Ok, I fixed the exhaust and put a Die Hard in it tis winter) With a Whipple and supporting mods, I still have the original clutch at + 70K! Seeking Advice. Someday , maybe sooner than I...

Why did Ford discontinue this nice replacement motor? Ford Racing 5.0l dohc aluminator supercharger-ready crate engines M-6007-A50SC

Back in June of 2015, while enthusatically accelerating off an on ramp, My Cobra had the O2 sensor bung blow out. I attribute this due to 9 years of thermal shock cycling and that the air conditioner condeser allway dripped on the pipe. Stainless Works replaced the downpipe at no cost...

Technically consider it a "crate motor"! This little puppy arrived on our loading dock. My first thought is if it had 2 more cylinders, it would look good under the hood of my old 03. See: http://www.roushyates.com/EnginePrograms/SportsCar/tabid/123/Default.aspx PS this is a show...

i thought it was 16 gallons. Is that to fully topped off or just to the gas nozzle click off point? Today I luckily made it to my Shell Station to get 93 octane. I did 3 round trios to work at 324 miles on the tank. After a very complete fil, it took 15.1 gallons. I was sweating as the...

Roads suck, and there still snow in the woods and in piles along the road but snow is going quick (I hope.) The temps hit 60-70 F occasionally. Subaru Foresters (14 6MT Premium are boring safe dependable transportation appliances. I should have forked out the dough for a WRX, but the gas...

What if any modifications are required to fit AFS Wheels size 18 x 10.5 + 27mm offset, 6.9" backspacing? What ois backspacing on OEM 17 X 9' rims? What is best rear tire size to fit without rolling fenders? Thanks

Watch this video. 2014 C7 Corvette vs 2014 GT500 - YouTube I'm not going to criticize, as I still have my original clutch with +65,300 miles on Whipple Cobra, so I am not one for leaving the hole hard, but this guy needs to stick to roll racing. PS. A tune CAI and headers will get a C7 near...

These are my spare silver painted factory rims, I'm selling them to put toward a pair 0f 18 x 10.5 roms for the rears. Currently on my car with 255-45-17 BFG tires that passed inspection but will soon need to be replaced These will make excellent 2n'nd tire set of rims and before you mount...

What is a fair price for 4 17x9 OEM painted SVT rims in good shape? I'd like to put tuhe money toward AFS 18 x10.5 replicals for the rear, or any other same size wheel you could recommend.

I think a well tuned 03-04 gets better mileage than a comparable hp GT500. My Last 5 Tankfull’s MPG 21.4 22.2 22.4 21.2 22.9 I coast a lot, try as best as I can to avoid using the brakes. Over a tank full I usually hit + 100, Mph 3-6 times and let the tires loose traction a few...

II traced the problem down to the T56 Transmission not pushing the plunger down far enough on the back-up switch to complete the circuit. I suck an Allen wrench in the threaded hole to the BU switch to try to feel movement when my wife put the car in and out of reverse and could not feel...

Would you give up 19% in power to weight, i.e. about 1 second and 10 MPH trap, 10 MPH of top end for: An extra gear in and a more sophisticated manual. Brakes that more than likely will handle track conditions better. Better ride and nimble handling, steering. Sharper interior, ergonomics...

I just posted a similar thread over on the 13 GT500 forum to get some feedback. My 03 is nothing special, and was wondering how it pulls compared to the 13 GT500. I'm to old and scred to do much roll racing to crazy speeds, so some forum feedback makes for good bench racing. Has anyone...
