Yo so what is the most HP I can get out of my Fit with all bolts ons? I am staying all motor and want to know what I need as far as header, intake and exhaust and should I add a super AFC or something like a greddy emanage?

 

I/H/E/Pulley/ lighter rims/lightened flywheel and tune most likely good for about 25hp over stock.

 

cool, not too bad.

 

smaller tires will give the illusion that you've got more power.

 

you'll have the same amount at the flywheel but you'll be putting more of that power to the ground with lighter wheels

 

I see a lot of you guys have that T1R carbon intake. How is that and is it worth the money? Or should I go with a cheaper Fujita or K&N?

 

Smaller wheels will give that illusion. Lighter wheels equates to less drivetrain loss and more Whp.... I had the opportunity one day to hang out at FourStar motorsports in Georgetown Ontario. These are the biggest Rally guys in Canada and run about 15 Rally teams out of their garage. They were dyno tuning their 2 Suzuki Swift rally cars and going from the Stock 14" Steelies to 16" Compomotive rally rims and lightweight dirt tires they gained 6Whp.

Think about it. If a pulley can get the fit 3Whp for taking 1 lb of rotating mass off the engine. What would removing 20lbs of rotating mass do?

You'll never see this on a dynapack where the dyno units bolt to the hubs. But on a mustang dyno the differences become VERY apparent.

 

Most WHP Ive seen is 107whp. Intake, header, cat-delete, exhaust, underdrive pulley. He then dynoed 198whp with nitrous.

Tunes give around 5-10whp also. But thats on an automatic I believe?

 

Every 1 lb of rotating mass removed, at least with regards to wheels, equals ~10lbs of weight removed from the car -- i.e. 20lbs of rotating mass removed would have the same effect as lightening the car by 200 lbs. That's pretty substantial indeed.

 

So to sum everything up, tune your car by instally quality parts that are significatny lighter then the stock and you can gain a significant horse power increase.

Modifications like lighter wheels, pullys, crankshaft, flywheel, and many other parts can increase overall HP.
