Looking to do better at the drag strip with the 2013 GT500 this summer and wanted to get a set of drag wheels/tires to replace the factory 20s. I like the look of the Racestars but wanted to know if the 17x10.5 will fit without modifications to the sway bar and brakes? I know they make 18s but...

2003 Cobra - car shut off while driving the other day and after inspection found power at the pumps but no fuel pressure - order new Deatschwerks 340 lph pumps and a PPRV delete kit, after the pumps came in and the tank was dropped I found the fuel line was corroded and that was the problem but...

Maybe its just me but it sounds like it is getting chunkier the more I use the red key. Exhaust is stock other than the side pipe restrictor plates are out. https://www.youtube.com/watch?v=OPorq0lacKk https://www.youtube.com/watch?v=nLW4EUl9B3I

Just Installed Michelin Pilot Super Sports on Boss 302S wheels. Tires are noticeable stickier than the stock Pirelli's but not as grippe as the Toyo R888's I replaced.

Just got these fog light delete covers - what do you think. Before After

2013 Boss 302 #3170, Grabber Blue #375 - Delivered August 27, 2013

I am looking to go to 18" AFS Cobra Replicas and I am wondering what brand and what size tire to go to. I want to go as wide as I can without rolling the fenders and I want a sticky street tire. I currently run P315/35R17 ET Street II's and they hook well but haven't lasted very long - my...

Looking to replace my Nitto 555R's with a more aggressive tire for street/strip. I like the look of the Mickey Thompson ET Street Radial II's but I'm not sure if they are a direct fit or if they will rub. The size I am looking at are 315/35/R17's and I currently have a 10.5" rim with the low...

Does anybody have a sound clip of Snakebite Series blower at idle? I am considering going this route as I don't have a ported blower yet and the cost is roughly the same as porting and doing a lower -without the worry of lower causing issues. I don't want it to sound like a procharger or gear...

Trying to decide on a whipple 2.3L with a 3.25" pulley or getting the eaton ported and going with a 2.93 upper / 4# lower combo. With either set up is a bap, 60# injectors, and a maf extender the only supporting mods necessary, also wondering the power range of each setup? Any recommendations...

Just got back from a day at the track and managed a best of 12.30 @ 116.79mph. It seems like the ET is low for that mph. My last round of mods were Steeda catback exhaust with weld in Super 44's (replaced stock catback with weld in Super 40's) and a 2.80 upper pulley & whipple tensioner...

I just gained 50rwhp/14rwtq by adding a Steeda Catback and a 2.80 upper with a whipple tensioner. Previous Setup 2.93 upper JLT Ram Air Intake Stock Exhaust Dyno Tuned 423rwhp/476rwtq New Setup 2.80 upper Whipple Tensioner JLT Ram Air Intake Steeda Catback Dyno Tuned...

Just installed Steeda Catback and it is a bit too quiet. I am using the stock h-pipe and don't have plans to change it at this point. I was looking at Spintech Pro Street Mufflers and Flowmaster Super 44's as I want the deeper muscle car sound without the blat. I'm want to be able to hear the...

I am looking at putting a drag radial on my car but I don't want to have to roll the lip of the fender or install spacers. I am wondering if the Mickey Thompson ET Street Radial II in P315/35/R17 will fit without rubbing? Also looking at Nitto 555R's and wondering which tire would be best suited...

My buddy bought a 2010 Shelby GT500 and is going to be doing some mods before the good weather hits up here in Canada and I am also doing some mods. I'm wondering if I will stand a chance against him or if I am simply going to be out gunned. My car is a 2003 Cobra with the following list of...

I should be around 450-460rwhp after the next round of mods - just wondering if at this power level a mid-pipe is going to net me any big gains or if it is just for sound? If I was to go with one it would be catted for emissions testing and I don't want that fuel smell that comes with the off...

I am trying to decide on a upper/lower combination or just installing a 2.8 upper - I am not as concerned with 1/4 mile times as I am with street performance - I want the car to feel fast in the 2-5k rpm range as I rarely run the car to 6500rpms on the street - after searching the forum I am...

I'm looking to increase power and still be safe without all the extra mods. My current setup is 2.93 upper, JLT RAI, weld-in Super 40's, and a dyno tune. The car made 423hp/476tq - I am upgrading the exhaust to a magnaflow catted x-pipe and Borla 14858 catback but I'm sure that alone is not...

Current set up is a 2.93 upper, JLT RAI, Weld-In Super 40's, and a dyno tune. The car currently makes around 12# boost, I am wondering if getting the blower ported will lower the boost level or if boost is effected by opening up the blower. Also is there enough seat of the pants difference to...

I am trying to improve my trap speed as I think it is low at 111mph. My mods are 2.93 upper, JLT RAI, Weld-In Super 40's, and a dyno tune with SCT Tuner Box. The car made 423hp/476tq on a Mustang dyno and the place that tuned it said the numbers were converted to reflect dynojet numbers. Here is...

I just had my car dyno'd for the first time a couple of weeks ago and I am wondering if my numbers are accurate or low/high? The car was dyno'd on a Mustang dyno but they told me it was calibrated to a Dynojet dyno. Does this provide for an accurate numbers and what is the calibration factor...

I am trying to decide which pulley to upgrade to but i want the stealth look so the pulley guard must go back on - i do not want to upgrade the cooling system or the IRS so I am not sure if i should even consider the 2.80 pulley or if i should just stick with a 3.1 - i have heard the whipple...

My buddy has a 2005 srt 4 that he has just put a stage 3 package on last week. Can anyone tell me what the car should run in the 1/4 mile - i know he is only using stock kdw tires and the car has been lowered 1 inch, other than a catback and a blow off valve everything else is what came from the...

I want to put goodyear eagle F1's back on my 2003 Cobra and I am being offered a great deal on a set of Eagle F1 GS p275/40/r17 but they are rated at 93w instead of 98w - i know the difference is in the load rating but will that make any difference on my car? the part number of the tire being...
