Hi Everyone,

Me and my son built a car this year and we are running at a 3/10 mile track and it's called Scotia Speedworld and it's in Nova Scotia. We are running a stock Cavalier and can do much to it. The Neon's are smoking the Cav's. I have been reading on here that people are running Cavaliers and not needing to shift to 3rd. The neon's at our track don't go past 2nd but we in the Cav's need to shift to 3rd. Does anybody got any help or ideas? There has been people tried the smaller and larger tire.

Thanks for reading .

don't forget... and it might be tricky...

front wheel drive GM cars.. use a CHAIN and SPROCKETS to change the ratio between engine sizes and body weights to reach a proper ratio for optimal power to weight ..

this is on both automatics and manual transmissions ..

there are also different final drive ratios..  where the pinion gear and the ring gear have different tooth counts..  i am NOT deeply into front wheel drive transmissions..  but its a THOUGHT...

you might want to check in some of the fiero sites.. as they list a lot of stuff for these changes.

Calculating Gear Ratios:
Divide your Driven Sprocket by the Drive Sprocket.
33-37 Set: 37 divided by 33 = 1.12
35-35 Set: 35 divided by 35 = 1
37-33 Set: 33 divided by 37 = 0.89

Multiply your answer by your Final Drive Ratio.
1.12 x 2.84 = 3.18
1.12 x 3.06 = 3.42
1.12 x 3.33 = 3.73

you did not say which of the possible transmissions you are using or even a year or close to a year of car ..

try to reply only once.. the system is broken and i have not found the proper staff member to fix it.. so moderators will remove additional multiple posts..
