A413 + Rpm

[gti_7]

Hello Fellow mopar fans :)

What is the max engine rpm an A413 can handle? Do they like going above 6-6500rpm? What about 7-7500rpm? Will a neon auto tranny be more suitable for these engine speeds?

thank you very much for your help

the neon auto is basically the same as the a413(just a little up dated)

AFAIK no special parts are needed to rev to 8,000+rpms, there was one that rev'd to 9,200RPM+ and at least 1 neon that rev'd to 10,000+ rpms but I'm not positive exactly if there were any issues or not with parts in the trans, I dont believe so.

Then main concern is actually making power that high

Yep, I don't really see a problem, just do all the tricks and tips, a good converter and have at her, ;)

[WickedShelby88]

Whose the best source for a good converter?

[Vigo]

i think the converter is usually the only worry in revving an auto but im not sure what makes one more suitable than another other than diameter..

ask glhs875 (iirc?) he revs his 2.2 auto pretty high.

I got my converter from Dynamic. They use a Hyundai(?) 8" body, and then custom build the internals to whatever you want. Smaller is better, especially if you're going to rev it. The cost was $700, though...

[Speedeuphoria]

All the DCR built auto SFWD cars and a couple other SFWD cars are using Nan converters now, 7" is the trick. DBLTRBL on here used to sell Nan replacement converters for reasonable prices(not sure what diameter prob8"?).

I went with an 8" from Pats Performance Converter, its a moded Saturn

I have a Relentless Performance Torque converter for sale if you want to buy it. It is one of the HD models that Gary Donovan sold a ways back. It only has 2-3k miles on it and is very tight. I have no need for auto stuff anymore. It is a non lock up model.

PM if you are interested... or anyone else for that matter.

That was great guys thanks for all the help. My reasing for asking is due to my wanting to hit 60mph in first gear. I have an A555 now with a 3.85 and it will be impossible to achieve without having to play with tire sizes and locating a a final drive in the 3.05 area. I figured it easier to get this result with an A413. I figure the less i have to shift the better my times. Anything else you'd like to add, my ears and eyes are open! :D:thumb:

heh, sure! you can hit 60 in first with the taller 413 builds but i honestly think you'll be slower that way due to less power to the ground from taller gearing. might also generate a lot of heat to be wot against the converter stall for the first 20-30mph.

i have never tried a 2.6 fd 413 but im pretty sure nobody can pull it off except for people with huge power and low weight.

but you'll have super sweet highway cruise rpms and be able to downshift into the powerband in 2nd from pretty much any highway speed. heh.

I might be interested in your converter. How much?

$350 shipped to the lower 48 states.

I think you would need to just forget first and start with second

but i "donwanna" :lol: i hear what your saying though. thanks for the link!

its possible to hit 60 in first with a 413 if you REALLY want to. 2.6 fd, high 5000s rpm and a 25 inch tire.. in other words, a perfectly normal TM with the regular 3.02 fd, all you have to do is switch the transfer gears to get 2.6 and you should be able to hit 60 in first. slowly.

[Murphy]

according to the calculator.......a 2.2(6500 rev limiter) with a 413(3.02 fd) with 205/60R15 tires should be able to hit 59mph in first gear

are you figuring in converter slip%?

[Murphy]

i did add it in, but looking at the calculator again, it doesnt actually do anything with the slip%

The Opel 8" cores are the best, but hard to find. The 7" is used in comp eliminator cars. The 31th has no problems going 10,000 + rpm. It's funny that the ATX's that DCR did *not* build worked the best....

I know they dont build a lot of things they sell I was refering to the cars he puts together.

It was funny I read a post the other day(srtforums) where the real guy(think your friends with him? Is it AJ? He built the trans for SMP also right?) said something about the trans and Darrel had to add his input that the new trans work better then the ones he used to built and dont use copies of his parts(which I dont believe). Also the guy(your friend?) said that everytime he posts on there his posts get deleted so DCR doesn't look bad, I can believe this for sure.

Why slowly ? 3.02 shouldn't be that horrid should it?

Maybe he means the tires will smoke all the way to 60 or the gearing is way out and will accelerate like a turd, :o

I don't know what the hoopla is about DCR? He seems to be the only game in town? The "new trans" is lucky to make 2 passes without some serious issues. The "old trans" went 25 to 50 passes before breaking the Ring/pinion gears... SMP was sold parts and given instructions on how to make it right....... I've got 7 years on mine that gets driven daily, and has lockup to boot.
