Boosted auto?

finally. someone with a brain.

Level 10 is rediculously expensive from what I heard. The next best thing you can do is run some type of aftermarket tranny cooler Im assuming.

gentlemen, gentlemen, gentlemen...

of course the transmission counts, tuning changes with the different shift points (i.e. differes between manual trannys f22/h23/h22)
and of course differs for automatic. everyone has said flaws into this thread, so obviosuly nobody has truely tuned other cars.
Everyone is trying to act like a so called "Expert" but in reality this doesnt seem likely.

you can not just buy a performance chip for any car. Every car/engine acts differently. scenario:
pike and dani have the same f22a1 and auto tranny in their cars.
No mods to each. They both buy a performace chip. It is possible the chip works but it was not tuned for each individual engine.
Every engine is different, has been beaten up by different drivers, so engine internals are not in the same condition.

Some tuning programs actually have a function where you do not need to remove your foot from accelerator
to shift and your rpms
don't run out of control.

I have briefly talked to Mr. blazen_accord about his tuning capabilities with the auto roughly 18 months ago,
wow its been a while, there is a lot to consider when boosting your auto. The thing that kills automatic transmissions
is heat. Heat is generated from in the transmission. The automatic transmission generates a lot of this heat, and
because they are designed to slip to provide comfortable, smooth shifts, they can wear prematurely when a lot of
power is put through them. The cure for this is to install a shift kit to increase the hydraulic pressure applied to these
clutches to allow them to hold more firmly and to slip less. The transmission will shift harder, and more noticeably, but
will generate less heat and last longer under high power abuse. A good transmission oil cooler will also be a big help in
allowing an automatic to live under abusive conditions.

The thing in the automatic's favor is shift speed. No matter what anybody tells you, an automatic shifts faster than
any manual, no matter who is slamming the gears. Additionally, power flow is not interrupted like it is when you step
on the clutch in a manual equipped car. Sure, some people can shift manuals without hitting the clutch, but those
gearboxes won't last long under all that abuse.

Building a manual transmission is just a more viable option for most of us in the import world as having a huge aftermarket
production line vs auto. And of course I am not claiming to be an "Expert" but just some information that needs to be shed.

thats the cost of building a performance automatic transmission. running an afterrmarket cooler on an old stock tranny would help some, but its hardly close enough to a full performance build to even consider it to be the next best thing.

that would be like saying a larger intercooler with a stock block is the next best thing to a fully built turbo engine.

its a step in the right direction but hardly enough in most cases.

Overall, in a straight line, drag-style race, automatics would be better. Yes, you'll go through trannies more often but you're able to load the turbo better than with a manual. With an auto you can utilize a tranny brake and lock in 1st/reverse. You cant do that with a manual.

That's why alot of cars that come from the factory with a turbo, are auto.

[dailydriVen]

i have always been under the same impression as mikew...a turbo builds boost off engine load..which is consistly held with an auto...which would lead me to believe it would be better in a straight line scenerio...but im no expert just my two cents

[MikeW]

That wasnt an impression.

That's what trans-brakes are for. Look at drag cars and cars that race in a straight line; most of them are auto.

The only thing manuals have over autos, in this case, is that extra gear. I know a number of guys who got into WS6's back in the day and they sought out all the manuals. It didnt take them long before they were putting autos in them.

[Dani Filth]

turbo autos are indeed good when they are designed for it, and the engine is tuned for it. the automatic transmission does tend to sap power but that can be easily overcome by increasing the boost.

however, boosting a 20 year old accord that was never meant to be boosted, and has probably been subject to years of abuse... thats a different story. work needs to be done so that the transmission can handle the boost (even a healthy stock one wont last long) and so the engine can be properly tuned for it.

im pretty sure automatic subarus, evos, srt-4 are fun to drive on D4 too

[Ferocious Cake]

how could a person successfully boost an auto?

I drove a GTP. Supercharged automatic. Honestly, it was pretty fun. At least the acceleration was. The car handled like poop.
A performance automatic transmission shifts faster than a manual can. Especially today's stuff. It also keeps the turbo under load. When built for performance, automatics can be quite fun.

how could a person successfully boost an auto?

Step 1, learn how an automatic transmission works.
Step 2, learn where your particular transmission will fail with boost
Step 3, buy and install the parts necessary to correct those weak areas.

They arent?

We're not talking about handling...

Oh, and I forgot to ask... Since when was there an automatic SRT-4?
The new EvoX with the automated manual or whatever it has is supposed to be great. And fast as shit.
