hay all what time should i roughly run down the 1/4 mile in my manual 2002 tj 3.5 mods below

h/duty clutch
extractors
mercury sports muffler
pod filter
unichip piggy back ecu

i know there are alot of factors ex how i drive and stuff but like just a rough guess

14.5-15 flat would be my guess

Yeah i would say 14.8-15.2...:) Goodluck. :)

cheers guys will be taking it to test and tune night one night ill let u know how i go :D

If it's your first time, there's a good chance you won't get anywhere near what the car do, so just go out and have fun and learn how to drive it at the drags.

E.g my best time was around a second slower than what I know the car is capable of, as I had no clue how to launch it (the sprintex makes it a bit of a pain to get to hook up as well). I'm itching to get back out there and apply what I learnt last time (but didn't get to apply).

It's all in the 60" time - every tenth you lose at 60" is apparently worth 2x in ET. Not sure about a near-stock NA magna, but I know manual sprintex'd magnas are capable of 2.0 60" on street tyres. Doing 2.4-2.5 60" times resulted in me getting ETs around a second slower than I know the car can do.

Here's some general tips which may help:

-Try dropping your tyre pressure to 22-25psi, this gives a much larger contact patch and therefore traction off the line.

- Generally with fwds the fastest way off the line is to slip the clutch a fair bit, to keep from bogging down. Dumping the clutch at high revs will just result in wheelspin, coming off the clutch at lower revs will result in bogging, you need to slip the clutch to keep the revs from dropping too low.

- The surface at dragstrips is generally much gripper than the street, so you will need to launch differently/harder.

how did you go?????

i will be going next wednesday to test and tune as i had to work on wed :(

Results??

I reckon it would probably be around the 15.6-15.8sec mark going by what the T'ville blokes are running. Hope you get it down pat, and good luck!!!

I reckon the magnas are very underrated, and often turn the Common***** owners white when they see how quick they get down the track. The engines in the magnas are quite solid, with a nice wide torque band to work with. Being FWD may seem like a handicap at first, but it does make the car around 100 kilos lighter than the RWDs, and there is less drivetrain loss.

I also recommend a suspension upgrade to limit the amount of axle tramp and also to stop the rear end sagging on the launch. I'm amazed at how quick these cars can get down the quarter, and have seen that Lucifer's setup is very well balanced (for eg.) It's great to see a car get times comparable to others that have twice the amount of horsepower available at the wheels, and make a shedload more noise doing it!!
