Will lightened flywheel speed up shifting in Model A?

I did a search and surprisingly didn't see anything. 4 banger, stock trans, I have to double clutch each shift and if I don't wait for the motor to drop a lot of RPM's it will grind into the next gear, this means I'm waiting for the motor to drop RPM's before I can stab the next gear, and always results in mucho downtime in acceleration.

My thought is the flywheel will allow the motor to drop revs much quicker between shifts, thus speeding up my o-60 times

I'm trying to plan out the next few mods, and the flywheel is kind of $$$$$, but if it will help a lot in shifting, not to mention acceleration and reduce the risk of crank snappage, then that may come before the high compression head.......

thanks

 

I've got a car with lightened fly wheel, and a car with stock fly wheel. I don't see much difference in speed of shifting on the transmission.

Lightened helps with acceleration though!!

 

If your rpms aren't dropping quickly when you let off, you may have a rich idle condition. Lean it out a little and see if it helps.

 

shoot, I never thought of that! I'll check my plugs tonight Though, it has seemed the same amount of lag time, and I've had the screws on several different settings just playing around. thanks

 

If you don't have a synchronized transmission, it has to be shifted slowly and gently.

 

The trans will still be syncromesh, and you will still have to double clutch. Go with a high compression head before a lightened flywheel for the most performance punch if that's what you're looking for right now.

To speed up shifting time, get a syncromesh trans. They make it in a stock Model A transmission. It's in the Bratton's catalogue.

MITCHELL MANUFACTURING
PROUDLY PRESENTS
MITCHELL MODIFIED MODEL A MAIN TRANSMISSION
This is a totally new main transmission in an original Model A Case. All new gears, shafts and bearings. New shaft rail, shift forks, spring detents, “O” rings on Bottom shafts, new bearing sealed both sides on front and rear main shafts. Synchronised 2nd & 3rd gear for easier shifting and guaranteed to stay in gear.

 

Yup, I was eying the trans, not sure if I want the trans first or the overdrive first, and not sure if I want to go the Mitchell route or assemble the trans from scrounged parts, or try and find a Columbia rear So many parts, so little rod budget!

 

A few driveline upgrade options that you may or may not already know about... They make a 3:27 ring and pinion for the Model A rear end. It's like starting in 2nd gear and then 3rd becomes your second gear and then having a higher 3rd gear. It's in the $350 - $450 price range the last I checked. If your hopping up an A motor, it shouldn't be to hard to start in second... No low end "burn outs" though, but you can keep up with traffic. Sounds like you're looking for off the line performance.

I wouldn't go with a torque tube overdrive if you're wanting to be speedy. They break.

Guy in New Zealand is making Model A quickchanges. I think 4ever4 put one in on here.

Theres a few guys that modify early 80s Ford 3 speed + OD transmissions for the Model A. Still runs closed driveline and bolts up to Bellhousing. That's in the same price range as that syncro A trans in Brattons.

Just some options for getting down the road faster.
