Hey I have quick question. Im going to the track on Saturday and I was wondering will it make that much of a difference if i take the spare tire out versus leaving it in???

 

Anyone know if it makes a difference???

 

any weight reduction is good........

Removing the spare tire is something I typically do when I go to the drag strip

 

Remove all your excess weight. Spare,jack(if you guys have one) arrive at the track with a little less than 1/4 tank of gas and you are ready to roll.

 

The only thing I disagree with is the gas....

Last time I was at the track with my old 95GT....anything less then 1/4 tank of gas, and I had issues hooking up...I was running street tires also.

Half a tank seemed to be about right...by the time I got done running I was down to about 1/4 tank....before traction be came a real issue.

 

You may be better off putting higher octane gas from the track if they are available. That will give you more hp and I think you will benifit more from that than removing tires.. But if you do both, then you are in the 13's with proper traction!!

 

That is a good question about removing the spare tire for when you go to the track. As already mentioned, it is good to have as much weight reduction as possible, but at the same time, you don't want to run into traction problems.

I am going to the track on March 30th. I am going to try it both ways. I'll have about 1/4 of gas and I'll try a run with and without the spare and jack and see if the benefit of less weight outweighs the risk of poor traction (no pun intended)

 

That is not correct....unless you are running a super high compression engine (which the Z cars aren't) or are using forced induction.....adding octane will probably HURT you not help you.

Why do people think race gas is going to help a car designed for pump gas?? It makes no sense.

 

I only have the drivers seat in my car. 1/4 tank of gas. LOst 20 pounds since last season on a diet. i hope to pull some good times this saturday.

 

or if your able to bump the timing up on a N/A engine ....but then again....it's not really necessary to run THAT much timing

just being a pain, sorry

 

would a injen CAI be considered a forced induction???

 

No...SuperCharge, Turbo = forced induction.

 

Sport Compact Car Mag got around 3 more HP when they dyno'd the car with 100 octane gas over the 92 premium they were running. So, inconclusion, our Z's MAY run better with race gas. I'm not saying to go out and put 110 in it, but once in while 100 may not hurt....
