95GTS said:Recent magazine (Motor Trend) clocked one at 159mph before the limiter kicked in. As far as the Cobra mentioned by UM, I wonder what the mods were. A chip at least but did it change the air-fuel and timing to make more power? Anything like that would mean it isn't truly stock unless on the speed limiter was removed.
Uncle Meat said:Explain how making A/F & timing changes to the tune in the factory ECM disqualifies it as being stock? Using that logic if I took a brand new 1967 Mustang and rotated the position of the distributor to advance or retard the spark, it's no longer considered stock? What if I changed the jets out in the stock carberator to richen or lean out the A/F? Not stock anymore?
It had Eibach springs to lower it, a Borla exhaust, Diablosport chip, aftermarket brakes. He was running in the "Stock" class according to the rules so that's stock enough for me! No, he wasn't 100% BONE STOCK like the car just rolled off the showroom floor, but it wasn't highly modified either! Most of the changes made were for safety and to eliminate the speed limiter.

95GTS said:You know as well as I do that changing the air-fuel or timing can increase or decrease hp/tq. The tune is no longer stock even though the car might be considered stock. We all know what a chip, cai, or just cat-back can do to wake up these Cobra's. Sure, it's still almost "stock" but hp/tq has been added to the stock capability of the car. Now how much does 20, 30, or 40 horsepower or torque add to the top speed of a car? I certainly don't know. I would think it would take a lot of power to increase the top speed of a car by even just a little bit. So maybe his mods have done nothing for the top end. You tell me.
Uncle Meat said:Oh, don't get me wrong man! I'm just stating that for all intents and purposes, and by the laws of the governing body that oversaw his speed record, he was stock. The mods he had were within the rules for his stock class
I guess we have differing opinions on what is considered stock and what is not. I feel that adding an aftermarket chip, or a flash tune does not make your car "non-stock", it's no longer showroom stock I agree, but it's still stock. You are merely fine tuning the very safe factory parameters in order to extract the maximum HP/TQ from the engine Ford provided.
The computer has the ability to change the A/F and spark advance or retard all by itself any ways! So our cars make more power when it's cold out thanks to the ECM's ability to automatically make the proper A/F adjustments based on the current conditions.

95GTS said:Actually I don't think I'm disagreeing with you, entirely at least. I believe the car to be a basically stock car but it has to have more power than a stock car with its few mods. But does that extra power (probably no more than 30) affect the top speed? I'm guessing but if those were his only mods, I would think it wouldn't increase top speed but only how quickly he got there.
marcus95 said:Hey Meat. I bet you wished you did'nt include that quote from last Septmember in this thread anymore. HUH? Just kept the 155 limiter in there only.
