ohh yeah and im running a single spinner 2.92:1 and was thinking about buying a 3.45:1 LSD but a Race Performance Mechanin told me to keep the 2.92:1 because it has a good ratio for drag racing? cheers

i dont know who told you that,, but drag cars use ratios like 4.11 and shorter?? using a tall ratio like a 2.92 will slow your launch and 60' times, where as 3.45's will speed it up..
3.45 would be a good investment if you can find one for the right price or if its and auto.. time for 5th gear -mitch

you would only be using 3 gears on the strip??
with a 3.45 you'll need 4th gear. so there is a trade off both ways with the diff gears. more power means you'll have to take the head off and have ported |

2800... Wolf and a BBM
Or, if you are weak, Smartlock conversion/bypass, EL ECU and BBM. 2.92's work in the EA cause the EAs T5 has different ratios. First gear is f**k short as. 3.45's might make it too short, maybe think about 3.27s?

2.92 is a great ratio.
good for drag racing and good for economy. i would keep it. since its a single spin diff maybe put a lokka in it for a better 60' time. http://www.4wdsystems.com.au/html/lokka.htm my freidns near stock EA ran a 14.7 with a 2.92 diff and went .3 slower with a 3.27.. so go figure. You could also benefit with a tight 3.9LSD. alot of the e-series guys are pulling great numbers with these diffs. Steady ED is right on the money. I would go an aftermarket computer and get it tuned up. Also chuck on a bbm manifold. Will defiantely see ur times stumble into a 14.5 or 14.4.. |

Rent a C-130, go to 30 000ft, and drive out the back, should get to 300km/h or so, lol. Save it and buy something better i say.

Well, with $2,500 to spend, how about a low boost turbo set-up? OR buy another car, because, by the sounds of it, she aint gunna go too much quicker.... |

Ditch the 2.92s, LSD 3.27 or 3.45.
What sorta cam you runnin now? Upgrade cam Change that f**k ugly brown dash!!! Chipped an tuned mate. Start thinkin bout puttin a bit more cash aside and look at a supercharger or turbo then you be scarin the v8's at the traffic lights(drags even)

i seriously dont understand why no one messes with the compression....11.5:1 compression and a water injection system will set you back MAX $1500 which will give you torque like a 351 Clevo
by the way.....doorslammers run diff ratios around the 5.33 ratio.......no where near the 2.92.....tell that mechanic he's got s**t for brains.

Definately do the diff change man. I went from 3.08 to 3.7's and dropped half a second off my quarter mile time with no other mods what so ever. This was in a commie though - but same rules apply in falcoons.
After you have done that get a decent cam By then you wont have much change out of the $2500. |

bah.. just read the cam bit in the original post - I thought you were asking which was a good mod.
Maybe look at a high stall too instead. |
