i dont have $3k to drop on a drivetrain. what should i do for now, to keep the tranny from becoming a smoldering hunk of metal that i see in my rear view on the highway? the boost will stay below 6psi i know that......

 

For what it's worth, I put a turbo in my car and 4 months later I replaced my tranny.

The biggest problem in the AUTO is partail throttle shifts. IT's still under boost and the VB mod will help.

Now, the VB mod needs to ADD line pressure to EVERY shift. 1-2, 2-3, 3-OD.

And keeping it under 6 PSI is a good start.

Also Beating the **** outta they tranny on a daily basis does not help

 

You could keep the tranny alive for a while, but your gonna have to be careful with it. That makes not to let it shift under much load, especially downshifts. Say your goin 50, I personally wouldnt floor it and make the tranny shift to 2nd which should be around 4500rpm. The turbo should be more then spooled be then and the "hit" might just take more out of the gear then it should. A safer way to do it for example (or so I think) is to manually throw it in 2nd, that way the tranny will already be in gear and already at full line pressure so slippage should be greaty reduced.
As baggs already stated the part throttle shifting will also be a problem because the tranny is at less then full line pressure.
I wonder if NRH could possible build the trannys pump to the point were its nearly at fully line pressure almost all the time. I know this would heat the fuild up quite a bit if is always over 250-300psi, but im sure its nothing a 12,000 lbs tow package tranny cooler wont take car of

One thing im really wondering about NRH is, could they possible...add a gear? 4th gear is quite long, but on the highway its at about 3K when going 75-80mph, with a turbo thats spooled at that rpm im guessing mileage is gonna suffer quite a bit. It would be sweet to have 1 more gear in there, while makeing 3rd and 4th shorter. Id personally want to gear 1st upward to say 50-52mph though if I had boost.

 

Call them and ask. They'll probably be able to do anything you want to pay for...

 

I will call once the $ is in my hand. Im definetly goin to "play" with some of the ratios thats for sure, and if adding a 5th is possible then that is also something that im definetly gonna look into.

 

He told me that we start running into ECU problems when changing or adding gears. I already asked for myself, since I like to play on the expressway.
But ask again, maybe you will get a different answer.

 

Maybe...just maybe if the ECU upgrade from technosquare pulls through for us 3.0 guys...I can give the guys there another $100 or something and have them "correct" the problem hell its a possibility

 

hyper sport racing in san deigo said that cryo treating my hard parts and using the level 10 is a cheaper and still a very good route to go what do you think guys? me and the car club drop the tranny crack it open treat the parts and used the rebuild kit. it can save me a grip. hey by the way how car i change the shift points?
thank you so much for your help so far

 

spelling all jacked <----- long night for me

 

1) How much money?

if it is near $2000, buy a 5-spd.

2) How much down time?

if it is near a month, buy a 5-spd

3) shift ponints are controlled by the TCU ( tranny control unit ) .. check www.cattman.com

YOU control the shift points in a 5 spd

 

your auto tranny will break so why spend all that money. All that level whatever crap doesnt work. Let alone I dont trust no SOB with rebuilt trannies. Had two bad experiences with auto trannies. I was not the only one. Theres another member here who was spraying. He paid a grip load of money in the name of Love for his auto. It broke again so much for that.

 

What about Ferhans ride? its still holding his isnt a rebuilt though, its a complete prototype from what I understand. Thats the one thing about the autos that makes me nervous, I know for a fact down the 1/4 if 300+whp is there the auto will either on par if not faster then a 5spd, that however is a whole diff story.
I would love to keep mine auto and turbo the damn thing, I know a 5spd would hold up but even the 5spd has its limit. Your going to have to cyro treat the gears at a point and even then you still have to not be an idiot and protect the tranny with your way of driving. Any1 thats boosted has to drive differently IMO, regardless of auto or 5spd. It might be fun to do a downshift into 2nd while goin 40-45 in a S/C car but how many times will the clutch survive that impact? Same with the auto, it basically comes down to how you drive it IMO. If you drive it like a bat out of hell, regarless of what tranny you got, something is going to break.

 

aight well i guess 5 speed it is how much is it going to cost to convert? i gotta get a beefy 5speed at that. vlsd and stout gears.

 

Well it all depends on how much you can find the tranny for, if you can find one for cheap it would help keep some $ in your pocket so you can upgrade it. The lighter flywheel, and upgraded clutch arnt exactly going to be cheap. Depending on how serious you want to get, go get yourself a quaife (use search) you can also get the gears cyro-treated. Plan to be spending in the $3K range. This is an expensive hobby

 

for all that hassel you should just go with a custom auto
IMO

 

see thats what i say it costs just as much

 

Your not doing enough research.



Look at the BOOSTED/NOS forums for guys who have BLOWN their 5-spds.


Then do the same search for the AUTO.

What makes you want an auto so bad?

 

For the same pric0e (or less) you can get a auto that will not blow and you can still hold your cell phone, drink some Coke, eat a taco with ease.

 

I know that, im most probably goin with the auto. If I cant add a gear im still going to mess with the current ratios so

As far as the 5spds blowing baggs, like I said...once you have that much power to play with, even a built tranny wont last (auto OR 5spd) if the driver doesnt know how to correctly apply the power. Like powershifting! why the hell would some1 with a S/C or turbo do that? your probably going to take some of the gears ribs off by doing **** like that. Same goes with extreme downshifts around 40-45 mph and drop it in 2nd, yes the rush of power is amazing but sooner or later your going to strip that gear. Even with the auto, you dont want to do that. Id personally try to aviod that
If boosted, the last thing I want to do is let the tranny downshift at WOT into 2nd at 55mph and watch the gear go bye bye. It might hold for a little while but how long really depends on the driver.

 

I stand corrected, you may not have researched who blew what, BUT YOU DO know what it takes to blow ANY tranny

Honestly, I think the AUTO is the way to go with the turbo.

The long gearing gives it an advantage when it comes to shifting, less shifting = more power to the ground.

and when it does shift the TQ picks it back up.

I hope you find what your looking for and let us know how it goes. And IMHO, if you can change the final drive ratio in the auto, that may be your best bet.

The reason being is 1&2 are nice, but 3&4 are too long.. even @ 8 psi in the auto the shifting into 3rd. 3rd lags ( WITH THE VI ) until about 90 MPH 5000rpm, then she rides unitl 130 and there is lag again until 140, but rides out after 140.. at least that is what the computer models tell me

 

I think 2nd gear us the worst gear in an automatic but I agree with baggs that 3rd and 4th need to be shorter.

 

I didnt really research anything to be honest with you I just knew a little bit of a problem that furbiss had, I dont know any updates as to what the condition of this ride ect... is at right now so I cant really make any comments on it, I shouldnt have to begin with.

As for the breaking any tranny, yeah I know...I speak from personall experience

As far as the 1st and 2nd gears, those two are just fine as is but I pesonally want 1st to carry out to say...48-50mph. 1st is the strongest so why not use it, besides while the other person has to shift you'll probably pull an additional 1-1.5 cars by just riding the gear. The thing I love about the auto w/turbos is you dont lose any boost when shifting so that combined with longer gears to actually ride out the torque curve should make for a devastatingly quick car.

As far as the final drive, well that would help 3rn & 4th but on the highway the MPG issue comes to mind. Thats the only reason I wanted a 5th, so I could cruise at 70 and not be at 100% boost. If 5th was an option for me this is how id set mine up.

These mph figures could be off my +/- 2-3, but still gives you an idea of what the it will reach. The sim is fairly accurate to the most part.
OEM-Gear Ratios 4sp A/T
--------------------
1st: 2.785 43mph
2nd: 1.545 81mph
3rd: 1.000 123mph
4th: 0.694 184mph
Reverse: 2.272
Final Drive: 3.789
Now if a 5 gear auto could be had, it would look a little something like this (for mine anyway)
1st: 2.44 52 mph
2nd: 1.48 86 mph
3rd: 1.12 113 mph
4th: 0.88 143 mph
5th: 0.62 205 mph
Reverse: 2.272
Final Drive: 3.789

With ratios like that on a boosted car, you should be able to run to 140+ with ease and no lagging
points. The 5th obviously is extremly long, but I dont see any reason why some1 would want to
keep pulling after 140. The second OD is just for mileage, and should keep the rpms down when
cruising.

Im not going to get myself into this mess for quite some time, but ill still be here in the yrs to come
so we'll see what happens, only time will tell.

 

my ride should be coming out of the shop soon and its gonna be hard not to run it at the track. and if i start it 2nd im gonna get whooped. but is thats what i gotta do to save my daily driver. and hit man when you start your protype 5spd aout i will be following your footsteps big pimpin.

 

if i start it in 2nd gear i mean
