Does anybody have mods done to their 84 crossfire, with 0-60 and 1/4 mile times to go along with their mods? I was looking for how many tenths of a second they improved by for each mod... :D
stock: 15.5 1/4 mile
chip,pulley,k+n,wires,cap+rotor: 15.1 1/4 mile
cat back,mufflers: 14.9 1/4 mile
random cat: 14.6 1/4 mile
air pump eliminator,throttle switch,shift kit,bosch+4 plugs:14.2 best but usually 14.4-14.5 1/4 mile
I dont have times for you since i never got a baseline but you could also try the following for a little improvement. Cut shroud for ram air, install 85 feul pump, remove swirlplates and port intake. MSD. Block the EGR. Headers, 1.6 to 1 Roller rockers. Gears like 3.42 is good that cars needs more top end. Unless you buildin a motor and getting new heads you might want to stay F.I. you can get an X ram and big injectors.

Those are all great baselines.. Another thing you could try is boaring out the throttle bodies.. they can be bored out to 2inch i believe.. All you need is new throttle plates which are fairly inexpensive... Also, check into getting a 7747 ecm from a late 80's chevy pickup. These ecm's are much faster than the 84 stock ecm. This will give you faster throttle response and greatly improve a msd ignition system.. Hope this helps :jester
13.6 @100.3mph two weekends ago at Byron Drags in IL. Some of the mods are in my sig below. I use the 7747 with a custom chip, TPIS headers and 2.13"TB's plumbed in parallel and running 80#injectors. I think I am running too rich at the top tho. Need some tuning to increase trap speeds.
Throttle positin sensor....it works at least for me...cut shroud for ram air...works great....MSD Coil in the cap....msd 6A......
K&N FILTER.....I'm trying to thing but the jack danials is catching up to me.....will give you more soon.....like whenever????????
March pulleys.......flowkooler water pump...fluidmaster damper.....etc....
'84 vette...no deal....but happy.....
