TERRIBLE 1/4 Mile time... What happened???

foxstang9050 · Jun 22, 2006

Ok so i went to the track tonight and im VERY dissapointed in my fox... before i did my converter and 28 oz flexplate it used to run higher 14s... well tonight something terrible happened and i dont know what... First attempt i had a bad late launch my own mistake but 16.1 @ 90mph... Second attempt launched on time and everything and 15.6 @94mph... I dont know what happened.. could it be my car needs to be tuned because it has been sitting for about 5 months i waited to do the conv and flexplate.. also i have a bent lf spindle and it pulls to the left (do to an accident a while back)... But it just seemed like it was running so slow.. anu ideas whats going on with my car???

did you also do a 28oz balancer?

Roland69 · Jun 22, 2006

what were your 60ft times....how old was your gas if the car sat for that long

foxstang9050 · Jun 22, 2006

In California they Charge you for everything... Meaning you get charged for every time you want... except tuesdays... it wasnt worth $9 for a 60 ft time... probly not good though because it launched real slow... the flexplate was already balanced

foxstang9050 · Jun 22, 2006

Oh yea and i put in 89 Gas on the way there5 Gal so i wouldnt have too much weight and traction problems

Roland69 · Jun 22, 2006

did you do a tune up from sitting for 5 month's

foxstang9050 · Jun 22, 2006

no... probly a problem... but no just got it running and went... and do you think the bent spindle had any effect... it pulls hard to the left

Roland69 · Jun 22, 2006

could cause some drag

94gts · Jun 22, 2006

what i mean is that if you have a flywheel/flexplate balanced for 28oz that on the opposite side of the crank (the harmonic balancer) you also need 28oz so the motor is therefore "balanced"

foxstang9050 · Jun 22, 2006

Oh well then no... so does that mean i need to get a new harmonic balancer?

94gts · Jun 22, 2006

if your flexplate has a 28oz balance on it then you need a harmonic balancer with a 28 oz balance. if the stock balancer is on the car then your motor is way out of whack because it has a 50oz balance

foxstang9050 · Jun 22, 2006

Ok well thats probably a problem then i'll get right on getting a 28oz harmonic balancer

Roland69 · Jun 22, 2006

makes sence to me.....but I would think something else is holding you back too

Jaswir · Jun 22, 2006

yea dont drive it untill u get a new balancer... could cause damage!

Not just "probably" a problem. It is a big problem. Running like that, especially racing @ the track will wreak havoc on your bearings. Hope nothing major happened w/ your engine. Don't drive the car until you get the new balancer, and next oil change cut your filter open and inspect. Hopefully you won't have any shiny surprises waiting for you inside the filter.

You don't need a 28oz balancer you need your old 50oz flexplate. Your motor is balanced to 50oz therefore the flex/flywheel and harmonic need a 50oz.

brands5.0 · Jun 22, 2006

Why would you put a 28oz flexplate on it???????????? Whats the reason did someone tell you to?

yuk · Jun 22, 2006

Yup.

Unless its an early 302/351W its going to be 50oz external balance.
