My Day at the track...(jet chip tested)

[Cliff]

I went to the track today in fear that it would close soon, but then learned when I got there that I have all the way until the end of DEC, so I was pretty happy about that.

My times didn't come out as good as I had hoped. I DEFINITELY thought I was going to hit 15.2 - 15.3 with my mods but had these results:

Run 1:
15.781 @ 86.784 mph, Reaction .874 JET CHIP OFF!
Run 2:
15.756 @ 86.746 mph, Reaction .599 JET CHIP ON!
Run3:
15.756 @ 87.675 mph, Reaction .107 JET CHIP ON!

Now as you can see my launching was getting better and better as I was getting used to it, but by the 3rd run where my launch was almost perfect, my 1/4 did not even improve, but my top speed was faster. This doesn't quite make sense to me, can anyone make sense of it for me? All runs were done at sea level, with my subs taken out, and on less than a 1/4 of a tank of gas.

Now what I was really disappointed is that the jet chip made absolutely no difference in my quarter mile, I think its safe to say that my quarter mile improved the second run because my reaction was much better. Im ready to just rip that thing out of there. With a CAI, Flowmaster Exhaust, Thermostat and Jet Chip I figured id break 15.3s, but in the very cold dry air today came up short.

Let me have your comments please. Make some sense of this!

Reaction time has nothing to do with 1/4 mile runs and how did you get a .107 reaction time .500 is the best you can get. Which track did you go to?

Mr. Farzettea(<spelling) is right there little buddy!
Don't feel bad I got a 15.5 with a reaction of .571
I dialed in at 15.2 thinking I would be close but was the first time I ran. I know I was spinning way too much tire out of the hole but
are YOU shore you where launching good and warming the tires enough.

[nfsga]

Yeah R/T doesn't have any effect on your overall time. If you want to see how your launch affected your times, look at the 60 foot times on your slips.

That isn't entirely correct... 0.500 is the best you can get without red-lighting, unless you are running a pro tree (ie, the top fuel and pro-stock guys), where the best you can get is a 0.400. You can get a 0.002 if you really have the urge, but I wouldn't do it during a race. You can also get a 10.000 RT (again, not recommended for a race) and your 1/4 time will still reflect how long it took you to trip the lights between the starting line and the finish line. Ahh... its nice to see people think they have faster cars than they really do... Kinda how I felt after I raced my car for the first time after the new cam install and was slower than previous times....

[Cliff]

Yeah my tire spin was minimal, but I really didn't warm the tires too much before staging either. Quick spin then up to the line I went.

Anyway here is my reaction vs 60 ft, which doesn't seem to make sense to me either:

Reaction .874/60 FT 2.387
Reaction .599/60 FT 2.353
Reaction .107/60 FT 2.386

My 3rd run had the best reaction time, yet had a worse 60 ft then my first run, figure that one.

Do you think I should have warmed my tires more? How about my launch? I power breaked her up to about 2500, i've heard people say as much as 3500, whats the best rpm limit?

Oh and I went to Long Island Motorsports Park....www.limotorsportspark.com

perhaps you are not understanding what nfsga is saying here. You could have a r/t of 10.0 seconds and still get a 2.3 60' time. R/T really only makes a difference if you are racing against the other car. If you are racing for time, it won't affect your time at all.

I found that the JET really helped me, the more work I did the better it made that car perform. I went from a 15.5 with it and just an intake and exhaust, to a 15.26 with the TB and a CAI.

My throttle response was really enhanced with the JET. You could feel the difference with it on...

Well I thought I could feel a difference with it on, but when the numbers came, i guess it was just all in my head. my CAI and Exhaust should have enhanced it a little bit right? I had no SVS light either...hmm.

I ran once with my pcu off and i noticed 1-2 tenths differce.

Your 60' seem alittle slow. Mine are .3 faster. Maybe if u worked on that you would hit your 15.3.. i dont know just an idea..

[jonwepa]

I think you mean 1.000 not .100 anyway get those sixties down and you will be alright!

Suggestions for gettin those 60s down?

[nnewton123]

put some drag radials on!

I was afraid you'd say that =( I'd rather spend all that money on engine mods - like the 62mm and matching intake manifold..

Work on them... What i do is when ever im at a red light ill act like Im about to race (I look for cops first ) Work on your lauch thats really I could say.

isn't a .104 a really good launch though?

[bszopi]

A .104 launch isn't good if you are trying to win a race.... because you just lost. Any reaction time less than 0.500 means a red light which means you just forfeited the race. If you aren't racing, don't care about the lights, etc... then sure its a good launch. But so is a 10 sec. RT.

Well I am just trying to get the best 1/4 time possible out of my car, nobody at the track was half as slow as I was. I was the slowest car there by far.

[SHawk670]

Doesn't it take a while for the car to adjust for the Jet Chip? I know with stuff like Intake, Exhaust and such the car needs to "warm it self up to it". I though the same were with chips. But im probably wrong.

ok here is my .01....the Jet is a waste..plain and simple. I have found that I ran quicker times by not power breaking...I just keep it at idle and punch it at the light...I dropped 2 tenths by doing that...my car was getting quicker at each run, but I ran out of time so I didn't get to drop it any further.
