Here are my results of going to MIR last Sunday morning. Track was prepped well as usual.

1) 13.048 @ 108.10 (54F)
2) 12.962 @ 108.77
3) 13.034 @ 107.17
4) 12.946 @ 108.66
5) 13.109 @ 106.12
6) 13.157 @ 105.47 (62F)


My car that day was 4140 lbs with me (225 lbs) in it. I was very low on gas and everything from inside the car and the trunk was removed. That morning a Silver 2013 Camaro SS was running 13.1x to 13.3x @ 110 to 114 mph.

 

Awesome! You've proven that with a few mods the STR is a high 12 second car. I'de like to hear your thoughts and results with Mina intake, hi-flow cats, and Dynomax VT's.... 12.8 sec. 1/4?

 

Nice, thats a bit better than they ripped off when new and stockand i still have trouble thinking about the high 11's being run with a new xfr. And to think my 79 elcamino when i drove it on the street with a 427 ran 12.00's now we have cars street driven that run 9's and the fastest street car in america series has cars driving 1000 miles to tracks and ripping off high 6's and low 7's regularly damn how things move along

 

Wow, when will the madness end?

 

Great job, how was traction with all of that torque? Thx for sharing.

 

good stuff!

 

Thanks for all your comments

Air Intake=
I purchased the car with 7K miles and it had an aftermarket air intake system with a small blue cone filter. I am not sure if it was by Mina or someone else.?.?.? The car ran pretty good when it was below 40F but was down an estimated 75+ HP during warm weather. It was a 14+ second car at the track. I removed the aftermarket intake system and returned the car to the OEM intake with a lightly oiled K&N and what a difference -- the engine had a lot more power!
Hi-Flow Cats =
They supply a bit of power but I had a bad experience with them. They were too loud and "both" failed.

Brutal:
From what I have seen first hand as well as read, stock STRs "typically" run 13.6 to 14.1 ETs. As you know, it is all about the engine water temp, intercooler water temp and air temp. As a kid, my neighbors had several Elcaminos (don't know the years) that they were always working on. They may have pulled the orig motors but they all had 454s. They did seem very quick.

I hope not until I'm 6 feet under!

How was traction with all that torque? =
Traction is rarely an issue for me since most all the tracks I go to are prepped very well. Also, my car does not seem to have as much torque as others who have installed the 2.6" (or 3 lb. pulley). At the wheels, I have 341 and others have 360+ torque. Last, I run 285/35/18 Continental DW tires on the rear wheels. They work well.

 

yeah in the older El's. Mine is a 79 and came with a 305, then a 350, then a 427, now a 580. yeah it never does end

 

Thanks guys, you make me feel sane again ;-)

 

What kind of 60' times were you getting? Also, how much speed did you gain from the 1/8th to the 1/4? Do you know your DA for the runs?

 

I'm heading to the track myself in about 5 mins will post my numbers when I get back

 

Select the "results" hyper link in my initial post and it should take you to another thread (post #18). All my time slips are posted near the bottom of post #18. I'm on my mobile at the moment or I'd post them here again for you.

 

1320racer et al, todays open air element intakes are isolated from underhood warm air. As the Ford Mustang GT500's isolated open air intake, the Mina intake is very similar in design. There's ample room and provision for fresh air supply to the filter element.

 

*******s. My track doesn't even have it's first test & tune until the end of April.

 

1320racer - I went to Palm Beach International Raceway yesterday for my first time ever drag racing. My times were 13.3ish, some worse after multiple runs and heat soak. I drove 15 miles to the track so I actually arrived with heat soak. I have a 1.5 # pulley as opposed to your 2.6# pulley.

My friend thinks my time would have been better if I wasnt using my 19" wheels on rubberband tires. Also, I was using the J-gate shifter and hit the rev limiter on all my runs. Do you use the J-gate or do you just let the automatic do its thing? I never used the automotic once but my friend who races also thinks some cars/people benefits from autos in 1/4 mile racing.

 

Under Pressure, you have your time slips? Post them up, we can see where the car was slow and where it was fast, bouncing off the rev limiter in 1-2-3 along with a slow/low traction launch could most certainly have turned a high 12 second pass into a low 13,
Your trap speed on the other hand (mph) will tell you just how fast the car is, as slow off the line doesn't effect your trap speed as much,

You hit the rev limiter because shifts 1-2 and 2-3 are short shifted by a few hundred rpm off redline; when you use the J-gate you inadvertently end up bouncing off the limiter in those gears,

I unwittingly did this too one of the first times I raced my STR, afterwards, I stopped using the J-gate when going for all-out WOT to redline pulls from a stop or low speeds,
I just leave it in D, with sport mode on, climate control off, and usually DSC off too,

I still use the J-gate when tooling around, holding gears and canyon-carving, but avoid it for full on racing. Even then, when you consider how wide the torque band is, keeping the engine on boil near redline isn't really necessary with an STR either,

Congrats man, hope you enjoyed yourself, and post those time slips for feedback, or at least let us know what you trapped!

 

13.3 isn't a bad time. Jag claims 13.7 sec. 1/4 mile. GT42R hit the nail on the head: Leave her in drive, DSC off, Sport on. Give her a quick but gradual depression of the pedal. She'll do the rest for a high 12 sec. 1/4.

 

I actually think from a roll racing, the transmission takes too long to down shift. So what I do, turn heat on at windows, close sunroof, windows, sport mode on, turn off traction control and manually drop it in appropriate gear. My favorite is at second gear, sitting at 4k rpms, third honk, floor it and right at 5200 rpms I manually drop it again to 5th gear and just continue flooring until the race is over. This always allows me to jump ahead because of the torque. You do have to be careful not to hit the rev limiter when shifting to 5th. The difference versus racing same car, that when I do this way and not just flooring is almost two car distance.

 

I have found that leaving the trans in D provides the best 1/4 mile results for my car. Our "sport mode" makes absolutely no difference when drag racing--it is primarily for road racing as it holds a gear longer once you let off the gas allowing you to turn a corner and still exit the turn at a higher rpm thus holding engine in the best rpm range to produce power as you mash the gas again--no time or power is wasted since you will "ideally" be in the proper gear for max acceleration exiting the corner.

I am not sure what wheels you have but if they weight more than stock that will have a negative impact. If the sidewalls are to short/small "rubber-bands" that has a negative impact too.

Extra weight, elevation, humidity, air temperature and engine heat-soak are the biggest determining factors on your times. My recent runs were in the 50s and low 60s and the DA was below zero. You are able to calculate your DA and corrected times on DragTimes.com.

 

Does anyone else ever have the issue of the trans not shifting out of first some times if you mash the gas too hard? Mine happens ever so often. It will be in D, and I will put "the pedal to the floor" and the trans won't shift. At that point, I move the shifter to the left and it will change gears finally. Really weird problem
