13.893 @ 106.54 (G-tech)
 

This is the result that I got tonight. My G-tech has been pretty accurate and I have it set up correct.

Car condition :

Stock motor (20,000 miles)
Stock turbos (100,000 miles)
Stock intercooler, computer
full exhaust, intake
Greddy pulleys
10 mm plug wires
air pump removed
7 psi max boost
badly slipping stock clutch
cheap 225 tires in rear (25 psi, stock rims)
240 lb friend in passenger seat
heavy stereo in hatch
1/4 tank of gas
spare tire removed
launch 4000 rpm

Results:

13.893 @ 106.54 mph
60' - 2.267
330' - 6.188
1/8 m - 9.229 @ 83.10 mph
1000' - 11.772
60 mph - 5.982 s

I got a lot of wheelspin in first and clutch slip in second. The car felt good despite the slow launch and weak clutch. It was done at night about 80 degrees with average Florida humidity. I think it's decent taking into account the car's condition.

Those numbers aren't bad considering your lower boost and extra weight. :) Do you have a .gtp file? I collect Gtech Pro Competition files.

Here's my last G-tech Pro Competition run. Don't laugh to hard at my 60 ft time. Oh, original motor and turbos with 23,000 miles on car.

1993 Rx-7 12 psi, mods in sig.

Here's the software needed to view the run data for those that don't have it yet. Just download the PASS (ver. 1.1.1)

No, sorry. Also exuse the late reply

Sorry, but at 7psi of boost you arent even at stock power levels and a fat friend doesnt help much either so those numbers seem a bit optimistic. Even more with lots of wheelspin.
Go to strip and get your time. GTech is only good to compare your old runs with your new runs if you do performance upgrades and you do it in similar conditions on the same road.

Funny how everyone has a lot of weight in the car and has a slipping clutch and the tires are bald when they post a 1/4 mile time.

well if he made 7 psi on the primary, then no transition as well...if no transition, no way it was 13.8 at 106. Also remember the mph is not the same on the g-tech as it would be at the drag strip or values in magazines you are comparing mph trap speeds with. G-tech mph are higher since it's the speed the car is going at the end of the 1/4 mile, while at the drag strip the mph is the avg speed (trap speed) for the last 60 ft of the 1/4, which will be lower than the g-tech value.

I agree that my G-tech is not 100% accurate. However, I remember the way the car pulled stock (new motor, lose to C5s by (1/2-1 car) , and it definitely felt faster with exhaust and lower boost. I think maybe my cheapy boost gauge is not accurate. But you guys are somewhat wrong. With the turbo system disabled (vacum line, sorry I didn't mention) the transition WAS noticably taking place. The primary pull was a little stronger than stock but weak in comparison to the ass-kicking that took place when the secondary opened, late and with a boost dip. Sorry about the "slipping clutch and bald tires" but that is the condition my car was in. I was not trying to impress anyone with my slower than stock time I was just excited because I just did it and it was decent. I have witnessed time after time bone stock FDs putting down 280 rwhp at 10 psi with only intake and exhaust. Is it possibe that at slightly lower than stock boost we can make a bit more than the stock 220? According to my $300 G-tech pro (that shows trap speed too high) YES. And my friend is 6'4 so he had the seat scooted all the way back, maybe I got more traction? Lighten up guys.......... ;)

ha!
