smarty and transmission

[MHorne]

OK i just got my smarty and have it on the 170hp setting. I have an 05 and damn that truck is fast. Quad cab short bed 4-wheel drive. My question is, how long will my transmission last on that setting? After the holiDAY weekend i plan on having it on the 90 hp setting cause my wife will be driving it and 170 on the weekends both with the added timing of course. If your thinking about getting a smarty i highly recommend it. a harley had a hard time keeping up with me. Anyway i'm gonna go drive it again cause man is it fun.

do you have any mods on the trans already? If not i don't think you will be doing what you are doing but for a couple more weeks. the Torque management of the smarty is very aggressive. you may want to put the stock management download in till you get some trans work.

 

[Vaughn MacKenzie]

Rule of thumb the stock 48RE auto is good for 80-100hp gain before you start hurting it, so sounds like you're beyond that.



If you're going to be using the power regularly you might want to add turbo shopping to your list too.

fill out your signature for everyone, it helps out when you ask questions. i just lost the clutch from running smarty on 90hp an my 120hp injectors. can't wait till new clutch cause i didn't get to go any further on smarty settings than #5.

Mine lasted 3 days and about 10 hard runs on the stock transmission.

It is the torque management programming on the Smarty which is killing the transmissions if I am not mistaking. The stock torque of the cummins is enough to kill the transmission alone with no torque management and hard enough driving... hence DC programming in the torque management. Another 170hp and 300lbs of torque on top of that would definitely expedite the situation.



If you download the the stock torque management program for the Smarty, I am curious as to how the transmission will hold up. I am waiting to buy the Smarty till I have enough saved up for some trans mods, but if the transmission will hold up on the lower power levels with stock torque management, I may go ahead with the purchase. Anyone running a Smarty with the stock torque management program care to comment on how it runs? I am curious as to how much of a difference the Smarty will make with stock torque management.

u need to worry about dropping a valve seat

 

[RBell]

Just curious about dropping a valve seat. What would cause that to happen? Haven't heard to much about the valve seats on the site so I would like to avoid that myself. .

u need to worry about dropping a valve seat

i don't think he has to worry about valve seats with just one box. that takes alot of heat and cylinder pressure to knock loose. the 05's should have the better seats in them anyway.



i would not run on the sw 9 program for too long or you will need a transmission very soon.

 

[JCutter]

Would you be able to get away with just a VB if you was only wanting to run a smarty? Would the TC hold up? Ive got a buddy thats getting ready to buy an 06.

Jeremie has the right idea. If your transmission is still working good, go ahead and do a vb and converter before you break something. In my experience, you can buy yourself some time, and you can use the converter nad vb when you do have to build the transmission.

Get away with "ONLY" a Smarty?

Guys, I'd like to remind you of the good ol' days. Back then a 300 Hp at the rear wheels was a HUGH power increase. A LOT of modifications needed to be done to get there...

Fast forward to today.

The fact that just one power adder can add hugh Hp to the rear wheels doesn't mean that it is save on a stock engine and/or transmission. "Just" a Smarty ( or whichever box, downloader yada yada yada)... yes it has become "easy" to up the Hp. Yet, you should always ask yourself, is it SAVE to use that kind of horsepower on a stock engine/transmission?

That's for ANY power adder!

Gentleman, you're on borrowed time with anything above 60 Hp on a stock AT and 90 Hp on a stock clutch. I'd also say that the stock turbo can not handle more than a 90Hp increase ( IF that ). Anything above that hp increase and the EGT's limit is the sky... What do the valve seats @ high temps???

I've done the dyno testing with Smarty on a stock engine, true.
BUT I KNEW that on the long run something would have let go. I was ready to fix whatever would've broke!

Are YOU your own warranty station?

In short, in order to be able to USE the power todays performance products can and do provide you NEED the supporting engine/transmission mods!

Makes sense?

A diesel shop telling someone not to worry about dropping a valve seat



I have a buddy that just put a new crate motor in his 06 because he melted it down running "one box".....

 

[Reb.B]

Listen up guys! thats what i'm talking about. Trans willl only take so much torque, flex plates, converters, clutches. As far as the seats go, lots of guys have been dropping them. Its more pronounced on 03-04 but i've seen lots of guys with 04. 5-06 drop already. How are they dropping,... ..... expanding too much and then loosening up or cracking and then loosening up, ... ..... either way its caused by too much heat. I'm not worried about 60 HP. I'm not worried about 90 HP under 70 mph, but floor boarded 90 HP and the 130 and DEFINATELY 170 HP will add too much heat. Tme and heat will take itstoll. Marco added the power in his programming because people wanted it and he flat out tells you were the safe mark is. Use your own judgement on whether or not u are perpared to lose a motor or trans. With a side note, at over 900 HP, i don't see over 1250 at WOT @ 120 MPH and on a hot day over 1350 at WOT @120MPH. There can be and should be things done so that if you want to run the hotter programs you don't ruin your motor. Take it for what its worth.

have you changed your valve seats?

with the power adders you have obviously you aren't worried.



i can tell you that im not worried about mine dropping and im still running a stock turbo. i run my truck very hard every day and have since it had 400 miles on it. as long as you don't see 1500 plus degrees on egt's and have stacked boxes. i have not seen seat drop from that yet unless it has been a defect. in that case i have seen more that have been a defect than actual failures. there are guys out there making 700-800 hp with out and head work at all. im not saying it cant happen but the liklyhood of it is small.

i also am not telling you to go and make 7-8 hundred hp with out head work im just stateing it has been done.

[RBell]

Reb, thanks for the info on the valve seats. When you talk about high temps I'm guessing you mean well above 1350 EGT. So as long as you keep those temps down you should be fine, is that correct? Thanks, have a great Thanksgiving everyone... ROB

No I haven't changed my valve seats ,and YES I am worried about dropping one. I have been at two dealerships and talked to shop mechanics who have put new crate motors in because of dropped valve seats. Some modded and one was on a BONE STOCK 05 6 speed. He uses it to hot shot and pulls big loads. If it will happen to him it will to me on a 1/4 mile run with the pyro pegged because the sps66 can't keep up.



I think it is very ignorant for anyone to say they aren't worried about dropped valve seats... For sure if your running big power on a stock turbo. Search the forums and check out how many valve failures there has been in the past. Not just on the 03-04's.

 

[RobertP]

well if you use common sense and not peg the egt gauge and stay within a decent egt. you will be fine. the only things that cause seats to fail is heat and cylinder pressure. i can tell you now that with my smarty on 9 and my injectors i am seeing only 1450 and the end of a hard pull. which is 200 less than i was seeing with the bullydog. so if anything i fell better about them.



so by me saying if he is only going to run the smarty and watches his egts and they are below 1400 degrees that he should not have any problems with them. "uken go stir the pot"elsewhere.



back on subject i would not run higher levels on the smarty without trans work. as for converter and valve body you will be fine. just don't do any hard boosted launches without billet shafts.

LOL. Your the one that stated that "you wouldn't worry about a dropped valve seat. " That is hilarious coming from a performance shop. I should've known not to challenge your knowledge.
