12s N/A possible?

Both Mark Williams and Dynotech steered me away from CF for the street. If folks are running them, that's fine but I'm not going to go against what the manufacturer tells me.

The Mark Williams MMC shaft was really lightweight, shipping weight was 22 lb. including box, packing materials, etc.
 
Heavier Flexplate will assist in keeping the revs up during launch.

I said a built transmission.... that includes a transbrake on a high stall.

Weight issue. If I could drive a 2900lbs Marauder I would. I don't care that the stock weight is over 4000lbs... If I want a faster Marauder... I need a LIGHTER Marauder.

I really haven't planned it all out... but in theory (as this thread is) with enough money (theory) you could get lighter wheels, lighter suspension, lighter driveshaft, CF hood and decklid, remove weight in the trunk... do what is needed to drop some pounds so you can net some ET.

Mach1s have the same engine rear end and optional transmission and they are in the 13s stock? Because they weight over 1000lbs less.

Dropping weight gets you into the low low low 14s.... then start adding the go fast goodies... 12s would be easy.

I disagree. More mass means slower revving. Manual vs Automatic transmission.

Boatloads of money for all this. A decklid will be several thousand, since you gotta have a mold made. MAYBE class glass would make one of their fiberglass hoods in CF.

I believe there was "talk" of class glass making a trunk lid not to long ago.

It is simple physics. The more weight rotating... the more inertia it holds. The snap of a launch will shock the engine down in RPMs.... add more rotational weight on the engine and the energy built is harder to slow down.

Since the engine has already revved up to the point it needs, the ET gained in the 60' is better than the minor ET loss due to building RPMs with the extra weight.

This has been known in drag racing for years. They don't use lightweight flywheels and flexplates in drag racing... that is for road/curcuit racing where the RPMs are constatly changing and gears are constantly changing.
 
I have never seen "the snap of a launch shock the engine down in RPMs" with an automatic. Launch and the rev's go up.

Actually all of the flexplates I've seen are lightweight. I will agree on the flywheel for manual transmisions but disagree on the flexplate and automatic transmission setups. The engine has NOT already revved to the point it needs to be, it is just below the stall speed and needs to rev quickly to overcome the losses in the converter. It takes advantage of the torque multiplication of the converter.

With a manual transmission, the opposite is true. The engine is revved up and needs to not bog down when the clutch is dropped because it immediately applies load to the engine and is a direct mechanical connection without torque multiplication.

If more rotating mass was better, everybody would be running 12" torque converters. And adding huge harmonic balancers on the crank snout.
 
Agree with Fordnut!

I agree with Fordnut on trans, flex plate and TC. My 60' second times suppport it. I have a SC with modest mods that cut 1.59 sec 60' times which are far better then many street driven DD Mustangs which weigh 700# or more less then my 4,500# MM with driver. My 60' times are the mainly the result of my suspension, tires and 3000 TC with a stock flex plate.

Maybe you should run lighter flexplates and they'd be even faster ;)

We tried with negative results on three different cars. Lighter flexplates loss us around .09 to .15 in the 60' but gained us marginal trap speed.

The combos that would help the ultimate goal (lower ET) were heavier flexplates to help absorb the transbrake hit.
 
Can we go old school and drop in a stroke and bored 460 into the engine bay? As far as I know there is nothing better than bigger displacement. How about shoehorning a 5.4 liter DOHC in? I'm sure that would make a difference. I remember back when, if you were able to make 1 HP per cubic inch that was fantastic, now we are pushing towards 1.5 or more? I remember when hot rodding a car was sposed to be fun and for your own enjoyment, whether stock, supercharged, or turboed. I'm just happy that I have a one of a kind car that no one else has around here. timfromme.

Yeah I started the thread, need XX amount of people to commit to it first with a small deposit before Class Glass would start anything. Their fiberglass hoods are cheap when you compare them to other limited production vehicles. I would only assume that a trunk lid would be less or around the same as the hood which is $450-500 right now.
