Guest louds38 Posted December 6, 2008 Share Posted December 6, 2008 Hi everybody, I've a T61 BL Supra auto about 550whp, and I'm looking to modified the transmission... I'm looking to the Boostlogic upgraded transmission but I've see that you can't use the manu mode with this. So I think to a TH400 BL convertion kit. I've made some research about the th400 ( how does it work, is it good for my little horsepower) but I have not find anything about it... Is anyone who have tested the th400 or BL upgraded kit with a new stall converter, can you help me please. Thanks and sorry for my bad english (I'm french) Quote Link to comment Share on other sites More sharing options...
dude Posted December 6, 2008 Share Posted December 6, 2008 If you want to go drag racing then the TH400 would be ideal with a Hi stall converter but you will have a very low top speed, the BL box has been proved to stand up to high HP but is never going to be as strong as The TH. I would recomend fitting a lock up switch to keep the gearbox temp down when you are cruising on dual carriageways, in fact i would say it is almost essential if you are going to run a Hi stall, AFR will be fitting one as standard to any conversions. We are also looking in to using an allternative 4spd auto that will take a lot of power reliably,more to come on that one. Dont forget that you will need to run large trans coolers and prob a trans temp guage, remember heat kills autoboxes. Quote Link to comment Share on other sites More sharing options...
Guest louds38 Posted December 8, 2008 Share Posted December 8, 2008 (edited) I will drag a little, but the most of time It's for everyday... Apparently, with the BL upgraded kit you can't use the manual mode of the autobox... That's why I'm "hesitating" between the both solutions.

tooquicktostop Posted December 8, 2008 Share Posted December 8, 2008 I dont think the TH400 would make a very good every day auto box, its a bit harsh The BL box is the way forward for your need IMO Quote Link to comment Share on other sites More sharing options...
paul mac Posted December 8, 2008 Share Posted December 8, 2008 (edited) Apparently, with the BL upgraded kit you can't use the manual mode of the autobox... That's why I'm "hesitating" between the both solutions. IIRC Boostlogic recommend you do not shift the box manually, something to do with the way the box is built, the definative answer would be best sought by dropping them an e-mail, why would you want to slow the shift down by changing manually anyway, i dont mess with manu at all, you just stick it D, floor it and blow everything away , if you really do want to shift manually IIRC when i was getting my BL a few years back i looked at the Sound Performance box as well, this is recomended to shift manually to get the quickest change, however i dont know if they still do them and they were nearly twice the cost of the BL the TH400 is a very old low tech box which has pretty horendous transmission loss'es, it is best suited to BIG turbos running very high power not really suited (or necesary IMO) on a T61 Edited December 8, 2008 by paul mac missed a bit (see edit history) Quote Link to comment Share on other sites More sharing options...
botachi Posted December 10, 2008 Share Posted December 10, 2008 My car used to have a TH400 Supra before it was brought down to more useable power levels and daily useability (and before I owned it, although the TH400 transmission was part of the deal, which I eventually sold off.) I'm back with a 6-speed. It's pretty hard to use the TH400 everyday, I think the way the transmission works, you can't downshift from say 3rd to 1st until you have to slowed down to a complete stop to get the gears to downshift smoothly. It's also pretty expensive so not worth it and it's pretty low-tech Quote Link to comment Share on other sites More sharing options...
michel lane Posted December 10, 2008 Share Posted December 10, 2008 The Th400 box is not the way forward if you drive it everyday, its stall will be to high and the conversion you will need to carry out wont really benefit everyday use. I would look at the boostlogic box. Manual does not work ?? all depends what ecu you run. I have a full manual setup if you are intrested, fully rebuilt using uprated plates and belts. The client it going for TH400 as he drag races . 900hp +supra for next year. Quote Link to comment Share on other sites More sharing options...

Apparently, with the BL upgraded kit you can't use the manual mode of the autobox... That's why I'm "hesitating" between the both solutions. I was in the same boat when I was thinking of updrading my stock auto, I loved to use the MANU-button. After reviewing my options, I just bite the bullet and got the BL box with a 3800rpm stall. The 3800rpm stall keeps you in the powerband at all times so I didnt even miss the Manu-button. I loved the BL box untill I burned the clutch packs a few months ago. I'm now going to do a 6spd swap. Get the BL box, you wont be disapointed and it should last for a good while unless you use slicks and drag race it alot. Mine held for only one summer, but I was running over 1.6 bar all the time with Mickey Thompson drag radials..

dude Posted December 10, 2008 Share Posted December 10, 2008 The box we will use will be reliable to around 600hp and can be built to your spec ie street, street/strip or strip in the way it shifts, you can have any stall you want and even a trans brake if your serious.

Guest louds38 Posted December 10, 2008 Share Posted December 10, 2008 The problem is that I want use it every day, the manu mode can if you downgrade, give to the car "engine break" (I hope you will understand)... It's very useful for daily driven, that's why I want to keep the manu mode... I really like the 6 speed getrag transmisson, but I've never found it, that's why I will have an autobox witch will be able to give me manual sensation...

With a high stall converter the engine breaking effect will not be that big compared to the original stall. I'd just forget about the MANU, I can promise you that you wont miss it with the built auto box. 2nd gear roll on burnouts were a blast Quote Link to comment Share on other sites More sharing options...

mrdsukautos Posted December 11, 2008 Share Posted December 11, 2008 I still have my BL box for sale with 3800 stally Only 300 miles on box total mileage Besdt part i only want 1500 notes for both box and stally contact me on 07969 974856 for full details dude Quote Link to comment Share on other sites More sharing options...
Guigsy Posted December 11, 2008 Share Posted December 11, 2008 i can count on one hand the ammount of times ive used manu mode. Pointless if you ask me. (apart form burnouts) Quote Link to comment Share on other sites More sharing options...

Pointless if you ask me. (apart form burnouts) The manu mode depend of how you will drive, sure for drag we don't have to change manualy, the autobox would do this better than you can... However, if you want it like me to street driving, to drag a little (very little time) and If I can with this for track (even if I thinks it's not possible), the manumode will be very usefull...

michel lane Posted December 11, 2008 Share Posted December 11, 2008 i think you are getting abit carried away on this "manual mode". With a high stall , there is no need for the manual mode especially on a 61 turbo, you are in the power band always. Changing in manual mode on stock form 1,2 on hard excelleration , your box wont last long. I have a customers gt35r running approx 540hp / 510lb using a boostlogic box and it drives really nice , i havent found the need to use manual mode. What sort of power are you running at the moment ?? if its a sp61 single with stock fuel system then you will be hitting .8bar before your injectors max out. You cant compare stock fuel system with a single with a complete setup with fuel system, the real power starts on singles at around 1.2bar. so to recap , if its a fully setup single you wont find the need for manual mode, if you do use it in this fashion , NO box would last as the changes would be to harsh for the amount of power you will be running .

My config is boostlogic t61 turbo kit, BL 4" exhaust system, map ecu 2, avcr, and this mont or the next month I will buy a BL fuel kit... In fact, I want the manu mode because I live in the mountain... There is some "turn" and when I will sportively drive, it's very dangerous then the gearbox downshift at the middle of the turn...

Well theres a few of those "turns" around here Just my 2p's worth I agree with most of the comments here. My PHR stage 1 is simular to the T61. Firstly you really need to sort out the fueling! If you're only going for around 550hp then I wouldn't go down the route of a BL fuel kit tbh Just look at JamieP's fuel system As far as the autobox is concerned I would defo go for the built auto that Michel is offering as the basic BL one is basically just a stock rebuild with standard internals! Plus Michels is a higher spec and a lower price As far as those "turns" are concerned I really don't think you would miss/need the manual mode. With a uprated box + 3200 stall + AEM I have found mine excellent when cornering. Just to give you an example when traveling say at 60mph (100KPH) approaching a tight bend I would be hard on the brakes and the AEM would drop the gear from 3rd to 2nd (whilst blipping the throttle ) when im down to about 30mph as I turn in towards the apex of the corner I would be balancing the throttle i.e. 30% TPS. Whilst balancing the throttle around the corner at 30% ish the AEM will not change down so TBH its really its all about the mapping and getting the shifts points altered to how you want the car to perform. Plus as said above the 3200 stall will give you engine braking. Quote Link to comment Share on other sites More sharing options...
