i was playin around with my new gtech lastnight. my best 0 to 60 time was about 8.2 seconds in my lo3 ws6 formula i didint think that was a very bad time condsidering there was a 200 pound pasenger and had 3/4 tank of gas. just wondering what you guys thought oh and my car is stock besides a 14x3 open air and ultimate tbi mods.

 

That sounds about right, maybe a little too fast. G-Tech's aren't known for their accuracy.

 

Absolutely! It is like comparing a Desktop Dyno to a real Dyno run by a real engine.

Might give you a rough idea / be close, but if you want real times, take it to the track.

 

Ditch the 200 lbs. passenger and run it again.

 

That sounds about right givien the conditions but that number can be greatly reduced the nest time you run. G-techs are pretty acurate when it comes to timing but are usually a bit fast when calculating MPH.

 

I agree. Back when I had my G-Tech, I ran a few passes with the G-Tech in the car, and the times were always no more than .1 off the track's measured time. The MPH was also consistent, but high by 2-3MPH. Why wouldn't the 0-60 time be accurate?

 

what do you think my time would be with just me in the car and about 1/4 tank of gas? i cant realy see what my time is without my dad in the car cause i only have my permitso itle be a little over a year befor i can see what my car realy has in it. and acording to gtech it can give or take about .2 seconds

 

You should be able to get that time down to the mid 7's. Cooler weather is a TBI car's best friend.

 

Highly, highly unlikely with a 700r4 car with a 2.73 open rear and just an open element - even with your dad out of the car. The cooler air arguement has nothing to stand on with an open element.

Keep the gas in the tank, it will aid with traction, which greatly affects 0-60 times.

If you had a manual with 3.23s or better with some other minor bolt-ons OR add headers and full exhaust with a posi unit to your current combo mid 7s is reasonable. Remember, a mid 7 second 0-60 roughly translates into a mid 15 second quarter. And you're not there, yet

ShiftyCapone may know more than I about the TBI cars, but his L03 performance claims are usually a little far fetched.

 

I may lean towards the fast side but that is only because I know so many people with near stock cars in the mid 15's. I realize this doesn't suffice for everyone, especially with cars nearing 15+ years, but it really isn't that far off. Perhaps I shouldn't lean towards the high end and instead redirect my average to reflect the overall of TBI cars instead. T5 cars are indeed a tad quicker, but the A4 guys aren't that far behind. Open elements may not be the best option but a lot of hot air is better than a tiny bit of cold air. The dual snorkel unit is a better choice and should out perform all. However, the open element is cheap and offers much greater potential than the stock single snorkel. Now if the engine bay is completely saturated with heat and the car has been sitting in traffic or on the starting line for an extended period of time, I can see where that argument holds complete merit. There are plenty of guys who have improved time slips with an open element though in the hotest of climates. As long as the car is running down the road enough ambient air should fill the engine bay and make a difference even if it is a few degrees warmer then what the single snorkel picks up. None the less you are basically right.

 

When I had my car, I put some washers underneath the brackets that held the hood on in the rear so it was lifted up about half an inch (side closest to the windshield). Isn't that a pretty common thing for hot rodders to do? Just for the record, I never noticed a difference.

 

I took the sound deadening material and weatherstripping off the rear of my hood to get more airflow through it. However, I have a TPI and a CAI down right below where the charcoal canister was before I relocated it a little bit. I did this at the same time I added my SLP 1 3/4" headers because I know how much warmer headers can make the engine bay. Don't know if it needed to be done, but I figured why not.

May help on a car with an open element. Sure couldn't hurt anything I wouldn't think.

 

well I have the stock cowl hood that came with my formula and I took out the peace of metal a replaced it with a mesh screen so I could get some cold air under the hood I think cooler weather might do something because it was a very humid 85* when I ran that and my engine temp was 220* so maybe if I put in a cooler thermostat and wait for a cooler day I might make some better times but we will just see how much of a difference that really makes its supposed to be in the 50's tonight im going to try and go out and make another run just to see how much of a difference that really makes

 

8.2 seconds???? Yikes
