Boostlogic autobox without Hi Stall

Recommended Posts

Howdy!

 

Can someone tell me if you get a BL autobox but not a hi stall wil it be ok?

 

i dont want to build a drag car, just a nice daily drive with borderline power for the stock box.

 

Do you HAVE to have a hi stall TC fitted to the BL boxes or will it be fine without one?

 

muchos! :D

A BL box is an uprated stock box which will behave exactly like stock but with frimer shifts due to the accumulators being wound up. You can use it with a stock stall converter if you wish.

 

But as Mig will tell you even a mild Hi stall will pep the car up like you wont believe, a 3800 is nice on the street and will put you in the 10's ;) But you must fit a lock up switch and learn how to use it.

Thanx guys

 

If i was mainly doing 1/4 mile's i'd def go with the 3800 TC too, but as i use this round town everyday plus some motorway driving i think the box minus the TC might be better>?

 

That will give me firmer and quicker gear changes and a bit of safegaurd on the box with the power ?

Bear in mind that quoted stall figures are just approximations. The actual flash point of a torque converter can vary depending on the load put through it. It can also vary between one converter to another. Just because it says '3200' on the box doesn't mean it won't start to bite until 3200. For example, the stall speed can often be lower than that quoted under light load/low torque scenarios; It can also be be higher with greater torque or more aggressive throttle inputs. Also worth noting is that with an aftermarket high stall the ECU won't lock up the converter as it's set to work with the factory stall point. This means that it will be constantly slipping under cruise which leads to reduced mileage, and more importantly, heat - something you want to limit. The amount of slippage, and therefore heat, depends on how loose or tight the converter is. To get round this you fit a lock up switch and engage the system manually at the required times, improper use of this switch can be detrimental to gearbox longevity.

 

Now everyones level of acceptability is different, so don't be surprised if you get 2 schools of thought on how 'nice' a high stall is to live with. But it's an indisputable fact that the further you change something from it's original design, the greater the effect it will have on driving. High stalls are great for those die hard traffic light warriors/drag racers with huge turbos who want insta-boost, but they do rob refinement, specially when you have to remember to flick switches and tickle throttles.

With all this talk of "round town" driving, "not drag racing" and keeping it a daily driver I still wonder why you would go single and not just turn up the BPU boost to 1.25 BAR and be done with it, it will still make 410+ ish BHP and be no expense at all, keeping full drivability

 

I loved my BPU auto, fantastic car which would run quick 1/4 mile times, as fast as a small single 6 speed !

 

You are in danger of spending a Fortune if not careful and then not being fully happy, I would get a test drive in a BL Auto with Hi stall if you can to test the drivability :)

 

My comments are only ever intended to help BTW, I have just gone through the single build several times and made MANY mistakes along the way, you have to be 100% sure what you want the car to do for YOU and get the tuner and mapper to deliver this, you should not take too much spec advice from a crowd, it clouds the decisions you make

Some sound advice there.

Thank you mate - your comments are very sound and i do take them onboard.

 

Even if my new single set up only makes 100hp more than what i have now i just like the whole single set up and power delivery.

 

.... the BL box may be a bit overkill for this turbo, stock auto might be better, i'm not sure? Lee said to do some digging on it!!

A stock auto box is cheap, in fact they are very cheap 2nd hand, just be ready to have to replace it at some point, this would be my view on it if you kept it stock

 

I fully understand the want to go single, its an awesome power delivery and experience, when I do look back though I did a lot of the tuning/changes/spec for this forum and not myself................ there I said it :D

 

It gave me a very very quick car that I would be proud to show off, it was a a cash cow however and I would have a BPU car over a single for daily use all day long now ;)

I remember Boostlogic writing that they dont recommend their box with a stock stall.

 

Titan Motorsports have come up with a new 3500rpm stall which will give you better drivability and better efficiency.

 

I had the PI3800 stall and it was fine for street driving.

You can get stalls that switch between stall speeds but they are not cheap.

 

whats the lowest stall you can get mate? 3200?

 

thinking the 3800 might loose some of the early spool the GT35R will produce which is why i just went for the box.

I would say the hi stall in my silver car was worth about 1.5 secs on the 1/4 and after a day or so was very easy to drive, the more torque you put out relative to the weight of the car the higher the stall, 3800 is pretty mild dude, the easier you drive the car the less you will notice the stall, a 3800 would be perfect for yours.

A BL box without a hi stall is like sex without latex and baby oil, still fun but you know something is missing;)
