dinop Posted April 9, 2009 Report Share Posted April 9, 2009 I recently bought my dream machine, an 09 Shelby and am wanting to do some small mods. I've been directed to Da silva racing but also want to see what else is out there. Any recommendations? Im thinking of doing the intake and tune. But would love to hear any suggestions from you guys. Thanks kindly, Dino Link to comment Share on other sites More sharing options...

dinop Posted April 9, 2009 Author Report Share Posted April 9, 2009 I called them, very friendly. Looks like I will be doing some mod work with them. I am tempted to do the SS. The wife would probably kick me out of the house!! Question though - What is the difference here and what do these do to the car overall? Is there a noticeable difference? I've heard about Gear ratio but Im not sure what they do Ask me how to flip an egg blind folded and I can do that. New to the car world M-4209-F373N - 3.73:1 GEAR RATIO $199 M-4029-G410A - 4.10:1 GEAR RATIO $259 Link to comment Share on other sites More sharing options...
dinop Posted April 9, 2009 Author Report Share Posted April 9, 2009 stupid me - I googled it. Does this sound right? Q: What exactly does a gear ratio mean? In the context of the final drive ratio (rear end), it's the number of turns the driveshaft makes per turn of the axle. So, on a 3.92:1 rear gear, the driveshaft will turn 3.92 times for every one revolution of the axle/wheels. Going to a lower (numerically higher) gear will increase your RPMs at a given speed but improve your off the line performance. A higher (numerically lower) gear will get you off the line slower but keep your RPMs lower at a given speed. Changing your tires will also affect the "effecitve" gear ratio. A taller tire will have the effect of going to a higher gear - this is why folks will go to 3.92s or even 4.10s when moving up to much larger tires than stock. A lower gear counteracts the taller tires to a degree. Easy way to remember: High number, high RPMs, high "kick". Low number, low RPMs, low "kick".

cobraracing Posted April 14, 2009 Report Share Posted April 14, 2009 I have used Steeda.ca in Milton for many years now for my tuning and parts purchases (great deals) Pat did an awesome job and increased 200 hp and 30% increase in fuel economy (I specified this and he spent quite a lot of time on the dyno) Link to comment Share on other sites More sharing options...
