How does 500 RWHP Feel?
#51
I just made the jump from 477 to 492. Havent been able to drive it since the upgrade but I am sure its awesome haha. At 477 the car was a beast but it defiantly needed to suspension upgrades. So I took care of that added some LT's and I am at 492rwhp. I am sure it rides much better now. Next on the list is some 10in wide wheels for the rear with some wide sticky tires!

Mine is sitting at 512whp now and honestly it is very driveable and usable, I drive most highway miles to way and get the exact same mileage as I did before the supercharger. It definately made passing on the highway alot easier. When you floor the car will sound amazing too espcially with mine being a convertible

Coming from my 08 GT (300 rwhp) to my Shelby (Currently in the 540rwhp mark) was incredible. The Shelby has about 400-500 pounds on the GT's but the reliability/ease of modding to get great power is much better on the Shelby. Yes you can get a GT to be faster than a Shelby with less money but for some people reliability is key. I daily drove my 08 and now I daily drive my Shelby. Stock it was fun. I did pulley, intake, tune once I was used to the stock power and it's a whole new animal now. I recently did muffler deletes (does nothing for power. Just sound) and it's just running/sounding great. Almost at 3k miles The only thing most GT500 owners will have to change from stock to pulley, intake, tune is probably spark plugs. Other than that the stock GT500 motor can easily hold 800RWHP I believe. I know several people in the mid 700RWHP mark on stock motors. Another thing you need to change on the GT500 when upgrading is the heat exchanger. Heat soak is real bad on this car especially with the stock heat exchanger.
If I were to give advice to someone wanting more power it would be the following.
1. Do it right; build and THEN boost.
2. Plan ahead; know what you want to do so that you can begin on supporting mods and not have to sell mods because they won't be usable with the future upgrades (for example: under drive pulleys and then a supercharger down the road..)
3. Always plan for extra power levels. You will think that 450RWHP is going to be plenty but you will ALWAYS want more power sooner or later. If you build then boost then the only thing you need to do is crank up the boost when you want more power.
4. Reach out to others. There are a lot of people that have done similar upgrades that you're most likely wanting to accomplish. Listen to others experiences so that you can avoid headaches and mistakes.
5. Be safe about it; don't try to jump from 300HP to 700HP. Adjust to new power levels in stages that you feel comfortable with. Mustangs are well known for allowing their rear ends to get loose. When in doubt, both feet out. Just let off the gas and the clutch if you begin to lose control and never SLAM on the brakes.

I can't tell you what 500rwhp feels like, but 490 is very streetable even on my drag suspension (no front sway). Launching on M/Ts at the track feels like a giant kicking you in the back with a soft leather shoe... awesome.

While my GT is still in the mid-300's, I've had many other cars as well as customers cars anywhere from 240 (in the case of the turboed mk II Supras) to as high at 1273hp (Twin Turboed Z06 with a 100 shot). What makes a car scary isn't the powerlevel. That 1200 hp vette was so sedate and controllable that you hardly knew it was worked until you goosed it, while the 240hp mk II supra's felt like you were skirting the edge of death and made you pucker your cheeks everytime you built boost. A car thats not set up to handle the power its making is always scary. All too often you see guys with crazy HP numbers, 20" wheels, no suspension upgrades, and even worse, on stock brakes with 5 year old brake fluid and Pepboys super econo brake pads.
I am building an S10 truck for track duty right now. While it's getting a 327 ci LS based motor with twin 66mm turbo's, I haven't even bought the shortblock yet. I am starting with the rear suspension and brakes, strengthening the frame and addressing any and all worn parts as I move forward, which on a 13 year old truck, is pretty much everything. I am building the truck to handle the power it's going to be making.
