: GTO was a turd in the 1/4
2004Goat 08-10-2004, 04:32 PM I took the goat to the track and here are my two runs... :angry:
1st pass:
R/T ... .123
60 ... 2.2226
330 ... 6.071
1/8 ... 9.196
MPH ... 79.12
1000 ... 11.86
1/4 ... 14.122
MPH ... 99.41
2nd pass:
R/T ... .228
60 ... 2.123
330 ... 5.962
1/8 ... 9.073
MPH ... 79.63
1000 ... 11.711
1/4 ... 13.95
MPH ... 100.79
Conditions:
-track was decent
-weather was a little over 80F
-humidity was low
-about 100 ft above sea level
-both runs were made between 12:30 and 3:00
Mods:
-cold air kit
-Borla catback
-BMR skit plate
Car had a little less than a quarter tank and with me in it weighed just under 4000 lbs
I launched both times at 3000 rpm and slipping the clutch for just under two seconds. As I fully disengaged the clutch I mashed the throttle and the tires would quickly chirp about 4 times. Every gear was shifted at red line (6000 rpm) .
Now this doesn't sound like your "mid 13's" GTO as you see in the magazines. Do the mags break in the motors before they test them? Do they wait for the perfect track conditoins?
I know that some of you might say it's the driver, track conditions or weather, but even if it was, the MPH should still be up there at around 105. 107 mph with my mods wouldn't be too much to ask also. If anyone has any suggestions or theories as to why I went so f*****g slow, I'm all ears. Wouldn't it p**s you off if you spent almost $36,000 and get less than you were told? :bs:
I'm gonna take it to the shop on saturday and put it on the dyno. I'll keep everyone informed.
gto_in_nc 08-10-2004, 05:17 PM Considering that you were in every measure beter on your second run than on your first, and considering that your car has very few miles on it (if I remember correctly), I dont' think those numbers are unreasonable. I'm curious about the "just under two seconds" of clutch-slipping, though. Sounds like a lot to me.
Nocturn 08-10-2004, 11:19 PM A, your probably just now learning your car, it always takes a couple of runs to get the habbit of running the track down.
B, your car probably isn't broken in yet, LS1's are notorious for running faster with more miles on them.
You might not be shifting at the redline if your watching the road, I know a few M6's who shift about 500 RPM before as they fear hitting the rev limiter.
As for your mods, don't expect any gains from the skid plate or the exhaust. The plate weighs a bit less but its not 100's of LBS, and the exhaust only gives 8-12 HP.
digitalgod 08-11-2004, 02:47 AM Most items I've read indicate the car hooks up best with a 2000 to 2500 rpm launch. This might help you get the clutch hooked up sooner.
forestdweller 08-11-2004, 03:24 PM how many miles on the car?
2004Goat 08-13-2004, 03:11 PM Forestdweller, the car had 1600 miles at the time. This is my first LS1 so my knowledge of it is somewhat limited.
Nocturn, you're right about me learning the car since I've only raced mustangs for the last 10 years. I hope you're right about the motor having to break in. I know that the skid plate doesn't do anything but I figured that I would mention it anyway since it's also a mod. Borla claimed only 5hp and 7lbs but that's ok. I got the exhaust to pave the road for future mods.
Digitalgod, I launched at 3000 rpm because that's how I've always launched my cars on a radial and MM&FF did the same so it felt right to me. I will try a little lower though now that you've mentioned it.
gto_in_nc, maybe I've been slipping the clutch a bit too long so I'll try it a little less.
I'm gonna be taking the car this saturday and put it on the dyno. This way I'll see if my rwhp will match my trap speed. I appreciate the feedback guys.
Nocturn 08-13-2004, 04:23 PM Another thing to mention, look at the 60" time, 2.2-2.1 is pretty bad (not saying its you but the car is known to be terribly hard to launch) so I imagine if you got some stickier tires you could easily see better times.

My 60 ft times are not my main concern. Look at the trap speed. 100 mph!!!!
forestdweller 08-16-2004, 03:12 PM I'm not an expert on the LS1 but as others have said it really benefits after breaking in. I would wait until you had atleast 4k miles.
Nocturn 08-16-2004, 08:16 PM Well look at the correlation, the shorter 60' time you had the better the trap speed.

As a matter of fact both my 2002 z28, gto got stronger after 4,000 miles. :)
woodnut 09-03-2004, 11:24 AM I have a question for you all. I used to have a turbo car, and now I have the NA GTO. I loved the turbo saab...but I really love my american goat. I have read when putting a cold air intake on a turbo car, you can loose a little bottom end in lue of the turbo lag you already notice. One, is this true? If so, would you loose a little bottom end in a NA car when you install a cold air intake? Just a question. WHen I mention NA...I am referring to naturally aspirated ofcourse. Thanks so much.

By the way I'm at around 13K now and the LS1 gets much faster with a little age.
Just curious did you have premium gas in your goat?
It makes a big difference.

No, you won't loose any bottom end, in fact you should gain mroe HP and TQ at every RPM.
CSiJason 09-11-2004, 12:11 AM Keep in mind the people testing these things in magazines are expert drivers and often use different timing equipment than a typical drag strip.

Actually most drivers in the mainstream mags suck. These being mags like MT, C&D, R&T. Better than a first timer, but they are quite a bit slower than the average joe with strip experience.

How could you not have premium gas. Does anyone run there goats on 87 or even 89. I thought you needed premium or else the engine will ping.
Nocturn 09-14-2004, 10:24 PM On the contrary, the GTO can be run wiht 87 or 89, the engine will retard the timming and thus hurt the performance, but it can be run with 87-89 if you so choose to, its just not gunna put out 350HP.
