changing cars

[fast75vega]

my bro is changing cars.. was running a 85 cutlass weighting 2900 pounds....456 gears.... w/10 slicks and a built 355 and a turbo 350 foot braking it... 3500 stall....was running 12.50's.

now he going to a 75 vega thats weights 2200 pounds...456 gears....14 x32 tire and his 355 motor and a 3500 stall... glide w/brake.........


we are taking guess's at to what it will in the quarter mile?

11.7 is my estimate.

I guess some where close to 11.90 at best for weight only because the tall tire with the same gear and a glide will put the engine to sleep at your power level, canceling most of your potential gains from the weight reduction. If you put the same 3 speed trans in the vega that you have in the cutlass you will go faster, 2 tenths or so.

lol...that what i was thinking too :wink: he talking about running in the 10's...... i almost pissed my pants laughing. i told him ....maybe with a 300 shot of juice..... :roll:

11.60 or 50s

11.90

I was figuring 11.8 with the glide , but thought the transbrake would improve the launch to about the same as a footbrake turbo. I also went with the smaller frontal area of the Vega vs the Cutlass. So, I'll stay with 11.7 as my estimation.

that about what i figure too. yeah he dropped weight but gained alot more rotating mass as well......... he's been talking s**t all week ... damn i cant wait till the reality check hits :D

If the car is set up right (suspension ect) I think it would probably run in the low 11.40s.

[fast75vega]

now he wants to go to a 5500 stall and thinks he will get into the 10's :roll:

I will go 11:70 now with the 5500 stall

WHAT DID YOU REMOVE TO GET THAT G-BODY DOWN TO 2900 LBS?

jeff..... the car was a rot box! he bought it for the motor and drivetrain.... it had nothing in it for floors.... the only thing that was holding the carpets up was the exhaust......not s**t :wink: everything else that could be removed was....but the doors and seats. it may off been about 3k... cant remember what it weighted when we scaled it?

[fast75vega]

well.... we dyno'd my bro's vega..... spun it to 7k and it made 505 hp at the flywheel and 474 ft pounds of torque ........ 390 hp at the rear wheels. so what do u think it will run in the 1/4 now?

one thing confused me though... it made 474 pounds of torque at just over 3k and then flattened out......but it has a 5500 stall! does that make sense?
