Hey guys i was chatting with a friend and he said that his (98? its one of those bodys) jetta 2.0 with a intake and chip will beat my sentra xe that has a a port and polished head, racing WAI, throttle cable mod , air breather (which i doubt do anything), new clutch and a short shifter kit. His jetta is a 5 speed 4 door and my sentra is a 5 speed 2 door. I said when we go to a track i that will get him on the 1/4 mile. I was just wondering guys who will win between me and him on the 1/4 mile? Lemme know fellaz....

It all depends upon how much the intake and chip will give him. I just checked the specs on the jetta which is at 115hp and 122lbs torque stock and your car is 110hp and 108lbs torque. However his car is about 400lbs heavier. It sounds to me like it will be close. Be sure to make no mistakes when you do race him at the track. Let us know how it goes
I have a monkey that continues the post whoring through out the night. His next stop is Pete's house where i taught him how to judo chop cracka ass thugs
yea if i were you i would study my cars behavior and find the perfect shift points, and practice, im sure you will win because its a nissan haha but lets us know hwo it goes!!
Well, I did a little research too, just because I was curious. The above stats on the Jetta are correct, 115 hp and 122 ft-lbs torque and I found that the stock GLS 2.0L is rated for a 10.1 second 0-60 mph time. I don't know if that is for the manual transmission, however.
Assuming curb weight measurements for both cars, the Jetta is 383 lbs heavier, to be exact (I'm not trying to be rude Sentragxe97, just doing some math...). However, the power to weight ratio all depends upon what each of your mods do for you. So, assuming that your car is the curb weight with 100 horsepower getting to the wheels, your PTW (power to weight) ratio is .043 hp/lb. If he gets 125 hp to his wheels, his PTW ratio is .046 - but that is assuming a far too efficent transfer of power on the Jetta. More realistically you're getting around 95 hp to the ground with a PTW ratio of .0405 hp/lb. Even if he's getting 15 more hp with his mods (130 hp at flywheel) with an expected loss of 20 hp when measured at the wheels (compared to the flywheel, if the car is very stock) his PTW ratio would then be .0403 hp/lb, giving you the PTW "edge" of .0002 hp/lb!
So, it really comes down to two factors (among others). How much extra grunt is created by his mods? How much horsepower is lost from the flywheel to the wheels on the Jetta? Obviously the curb weights will be low, but if both cars are analyzed low, then the ratios will still be good for comparison's sake. Oh, another important factor - driver ability. It sounds like this one could come down to a "quick shifting" contest. Good luck.
Yeah, now that I'm looking at the "mod" list, I see that there is nothing that would substantially affect performance. Essentially you're running a stock Sentra against a possibly beefed up Jetta. I'd say both stock would be an interesting race, but at this time, the Jetta might have the edge. It weighs considerably more, but his mods could improve it enough. You're not going to get any better throttle response until you improve the exhaust flow, and if the Jetta is still using the stock exhaust, his performance gains would be lessened. An improved intake will do almost nothing if you don't improve the exhaust output. That is, why shove in more air if it can't exit at an increased rate? Increased input demands a higher capacity for output.
Just to clear things Chimmike, I have sent a flexible home depot pipe up from the air damn to the heat shield filter. I have 2'' piping from where the cat used to be to the stock rusty muffler(50$ job supposed discount by a local muffler shop, to bad they are not mandrel bent pipes). I used to have a ricey exhaust but took it off due to to much noise and cop trouble. If u guys have any opinions on whats a good muffler to get lemme know. As for perfect shifts i dunno, My speedo broke about 20,000 miles ago and i didnt know what it was while replacing the clutch i found the prob and am in the process of fixing it. Damn u guys like busting peoples balls lol well thanx anyways. Hotshot headers are in the works for this summer but might get delayed due to a b13 se-r moving in.

So now you tell us! By using the 2" pipe you've at least allowed the exhaust to increase its flow rate, but the stock muffler might be somewhat restrictive. So you opened up the volume of the piping but "plugged" it somewhat with a muffler with a low flow rate. I have a 24" free-flow perforated core glasspack after the cat, and then a Dynomax Ultra-flo muffler, which they claim can achieve a volumetric flow rate of 1133 cfm (which I cannot prove or disprove). It has increased power quite nicely, though. This combo allows for a higher flow exhaust without sounding "ricey". It's not much louder than stock.
One more thing guys the engine chip he has is a "Z1 Performance engine chip" that gives a bs 25 horses. Ebay motorsports baby!
So then neither of you have modifications that would drastically improve horsepower from stock, and we're back to square one. It seems as if it should be a rather close race then. You might have a very slight edge on him if that chip is bogus, because his engine is only rated for 5 more horsepower, while his car weighs 383 lbs heavier (possibly more). It should still be close though, depending on how both of you shift.
Sounds about right. I know I didn't feel much difference powerwise in my sentra from my pacesetter exhaust system until I did the headers as well. Just make sure your car is running top knotch and that goes for your own skills as well. I watched my best friend(03 celica gts) almost get beat by a VR6 and it was only because the guy driving the VR6 was shifting like a pro. So basically this might not be about the better car but the better driver. Give us stats after you race him. Good Luck. Show him the taillights for us.
