i have a 3400 stall and...basically if you push the gas pretty far the RPMs will shoot up to the stall speed, if you gently touch the gas pedal, you wont notice high RPMs, they will go up faster like gears but other than that, cruising speed will be normal.

 

thanks for all the info! Here's the thread https://ls1tech.com/forums/generation-iii-internal-engine/602590-converter-but.html
says his tranny didnt shift and it bounced it twice...he may have a higher mile tranny, also his is a 98 like mine and according the some posts in that thread the 98 computers are a PITA to tune. i have 80k on my tranny hence the reason i was worried.

 

exactly, the only way the car would constantly stay at the stall speed is if you had a non-lock up torque converter. which you dont want for a DD.

basically the converter is a little looser, so you will have to give it slightly more gas from a stop and raise the rpms higher to get it moving. But it will only flash to the stall speed unless you give it a good amount of gas; say more than half throttle or so. once you get moving to say about 40-45mph the converter should lock up and the rpms will drop down to alot. People with converters only lose mpg in the city, for highway its almost the exact same. search around in the A4 section theres a bunch of videos of how these converters act on the street. one guy has a 4000k and at like 30mph hes at 1800. Oh and if your worried about it heating up get a tranny cooler. theyre like 60 bucks and will keep your tranny cool even with a big stall.

I wouldnt go as far to say from a roll youll be good. you still might be low in the rpm even from a roll, im not sure. go take your car for a spin and floor it from the roll point you plan on racing from and see where the rpm's are at when the tranny drops. remember the ms3 doesnt even start making good power until about 35-3600 and makes ideal power at 4000. thats why camscam is going with a 4000 stall to get the best results. Trust me, theres a reason people get a stall when they get a cam. im almost positive gears wont be enough to do it. also the car will suck to DD with no stall. at least thats what alot of people here say.

the way i look at it, theres no sense in getting a big mod like a cam and not going all the way with supporting mods. if your going to be spending $1000 on the cam, you might as well spend another $500-800 on a stall to really make the cam worth while. It seems like alot of money i know, but why half *** it? and as most know here, modding is not cheap lol.

 

Yeah thats me, the tranny didn't shift due to the tune. My tuner warned me with my fuddle that it may hit the limiter and if so it was an easy fix. I'm guessing the extra tq created from the higher stall was not expected by the trans, just gotta let it rev out a bit more.

 

gotcha, thanks for chiming in. i was going to pm you about it but you beat me to it. so your saying it was merely(sp?) a tuning issue and this shouldnt be a common problem? your car sounds nasty by the way

 

Yeah should just be a tuning issue, I actually broke a spring recently but once the car is back together it'll go to my tuner and get sorted out. I'll keep you updated if you'd like but it may not be for a couple of weeks. I'll also try to get video up of the car it seems to be a whole new beast going from a broken fuddle to the yank.

 

definetely keep me updated, thanks alot for all the info.

 

ya cams im planning on spraying a 150 shot when i go2 the track. Will the dual spring handle the MS4 pretty well since that cam is so bad on the valvetrain? i surely dont want a problem child

 

The prc dual valve springs are "supposed" to handle up to .660 lift. so in theory you should be ok as far as valve springs. However, revving the cam up to its full range of power (6800 rpm) and spraying a 150 shot is just asking for trouble. If you were all motor, then you could probably rev up to 6800 rpms. Also high rpm revs are a killer on the stock 4l60e, especially with a 150 shot.

Here is my plan. Im using the ms3 cam, which also peaks at 6800 rpm, and im going to be spraying a 150 as well. Ive done alot of research and am planning on setting my shift points to about 64-6500 with a 150. i also plan on having an extra 2 grand set aside in case if either my rear end or my tranny takes a dump. My car has 80k miles on it so i know one of them wont last long.

 

ya the PRC springs should be good, but they are right on the verge! you will want to check them every 8,000 or so miles! the 4l60e is not as bad as many think and it will hold the power pretty well until it starts getting to hot! BUT YES Ms4 and 150 shot will get you in the 10's if you can drive the car well!

 

Well thats good to hear, and imonly planning spinning the motor to bout 6500 at most. So i figure it should be fine and im building my tranny now with HD parts so it will hold.
