H22 Autos?

[QUOTE=SMseagren83]

My mostly stock auto f22a1 has chirped many a time to second gear. QUOTE]

not that this comment is completely relevant BUT i just doubt that this is a regular thing for ur "mostly stock f22a1". its just very unlikely.

the f22a1 auto just doesnt produce that much power to "chirp" the tires to second gear on "dry" roads. maybe it was wet out? lol

lol, w/e dude, it's the internet, believe what I want to but I did the diy filter on stock tubing, muffler, and synpower synthetic. In 80f temps it'd do it on both the stock tires and even with the aftermarket 15's I had. It'd almost always scratch a bit from a stop, no brake launch or N launch. Not so much now b/c I have really sticky tires, but if I'm going around a slight turn the inside tire skips pretty hard.

Like I was saying about condition, my car is now only around 135k. I also know that torque converters can lock up and shift hard, so it could be a side affect from an adverson condition. I haven't changed the tranny fluid since I got it two years ago at 90k, but Ive heard that while clean in high heat/lots of short trips the tranny fluid in autos can break down much faster, and it gets quite hot here plus I do lots of city/short trips. So it's possible it was getting too hot and locking the torque converter up a bit. I added some transmission oil cooler (I know there is lots of controversy about addatives but I tried it just to see) and the torque converter and the whole transmission in general shifts much smoother(albeit it doesn't pull as hard when it shifts).... take from it what you want but this is my experience.

lmao at some of the comments in this thread. I have owned an auto and manual cb. From my experience a manual cb will always take an auto (equal mods of course, think about it....have someone experienced with a clutch drag both cars at the track, which do you think will pull faster times in all honesty?). Also have any of you guys researched about how auto trannies work...it's all about fluid dynamics with the tq converter. (read this http://www.howstuffworks.com/torque-converter.htm)

Sure you can get upgrades like a level 10 high stall tq converter; but you the power potential is still less than a manual. High hp automatics are possible obviously, but if you had a 5 speed in your car I guarantee you will make more power.

Another relevant issue...people wonder why our auto's are prone to breakage. Well like I said it's fluid dynamics (tq converter) compared to friction (clutch). The fluid inside the tq converter spins a turbine with turns your wheels, neutral dropping/powerbraking etc can lead to breakage of the turbine fins, differential etc...believe me I have blown one up. Part of that parasitic loss from an auto is because of the tq converter and the drag the static fluid inside it causes. As it spins up tq is applied to the wheels...if the drive gears engage fast enough on shift and the converter has enough tq (ie being spun at high enough rpm) you will get chirps like people mentioned.

Our trannies are also known for harsh engagement compared to other comparable cars so I wouldn't exactly say it takes that much power to do that...hell I've chirped the tires in my moms geo metro going into 2nd . All in all the power to chirp the tires or have a fast car is there with an auto tranny. It all depends on how fast your tranny gears engage(condition of tranny), the tcu you have, tq converter stall rpm, etc. There is a lot of stuff that goes into play when you try to compare an auto car to a manual.

Once again it's all the in the owner's preferences which transmission they prefer....as for me manual ftw (people correct me if I stated anything wrong lol)

^thanks, very good reply. Yes, manual always can put more power down in the same setup. The difference between the two can be more or less depending on the indiviual setup of course, and seeing as how we are mostly casual tuners looking for maybe around a decent 200hp or so for a decent daily setup if we can reach that, it's a matter of finding out the options we have, and if the gain from a manual for a specific aplication warrants swapping vs. staying auto (for those who aren't already 5spd). Many other make/model cars often have a nary .1-.3 1/4mi time difference between stock auto/manual. We all to a decent degree understand the physics and why one is better than the other and in what ways, this has been disgussed a hundred times in this forum and few of those have legit comparison information of the two setups originally asked about. .2-.3 may be little difference to me or you, the setup of the auto may have more power from the crank itself and end up on top, we just want some good examples of what different setups have actually run. Please someone already post some more specific examples. Like you had autoh22 ran____ in the 1/4 mi then went 5spd ran ___ in the quarter with same mods something like that we can use.

I'm too wordy but so far nobody has quite got what I always ask (good comparisons with facts about what different setups actually ran)

How do the Auto H22's run?Performance wise?Its a big upgrade from the H22 but what kind of boost in performance would I be expecting?

Im in a similar position bro cause im running a F22 with an auto H22. I was wondering the same thing until I did some research on the cb7 website. I think you might like this link out bro..
