Auto box for big power singles!!!

[dude]

Just a little bit of investigation yet but I have found a way of fitting a 4 spd auto that will hold up to 1800 hp:), limiting factor on turbo size would be the stall converter you are willing to run on the street, allthough I have been told of a little trick with NOS that can make a large turbo spool like a little one and uses very little NOS. More soon, might make mine auto for next year:eyebrows:

Is it the API 350 VR4 box? It can take over 2000 hp.

No dude the box itself and the build is relatively cheap, i'll let you know later just need to find a couple of things out.

Interesting

dude, can the na gearbox be uprated to recieve more power? looking into buying boost logics stage 2 na-t kit but the gearbox worries me as i want to stay auto and hear they can only take 350bhp any ideas mate?

Giving up so soon, manual for real men mate:D:p

Proper drag cars use autos - running a high HP Supra on the strip with a manual is like saying "it's OK, I'd rather run a 9 instead of an 8"...

 

 

Interested to know what box would be at the core of this Dude?

True, TH400 FTW.

Yep, or Powerglide - interested to see how you get on once yours is up and running, you have a great spec to put down some decent times

 

Problem with the established Drag auto options for the high HP Supra is the lack of gears without something like a Gear Vendors OD unit in the mix. Sounds like Dude has a new base that's 4-Speed already....

 

There was another option based on another yank box that was 4-Sp but I forget the model designation, I'm sure I've posted it previously somewhere.

[SupraHuman]

I can only see the gear vendor kit come into it's full use on motorway driving, on the strip a 3 speed should suffice giving the right TC and gear ratio. I would love to get the vendor kit, but it's silly money, would be ideal for the standing mile competition tho.

Intriguing (I'd be interested seeing this as well )

I`m out

[dude]

The set up is currently on a race car, it is an overdrive unit but it works in each gear, the trick will be getting the gearing in the box correct, the guy im talking to has it behind a glide but I would like to use a TH400.

[Miguel]

Unsubscribed. I thought it was going to be something new.

Sod you then !!!!!! Would be new if it was actually fitted in a supra.

It was

lol quite the marketeer Dude

 

For info (for those searching) - Powerglides and TH400's are ideal yank autoboxes to use on a high HP Supra when they are rebuilt / uprated for the job but are only really suited to the drag strip. In the case of the Powerglide it's a 2-Speed box and the TH400 is a 3-Speed box, neither of which are great for road use when you want to cruise for many miles - high revs, poor fuel economy etc.

 

You can add an 'overdrive unit' into the mix, such as the Gear Vendors item:

 

http://www.gearvendors.com/racing.html#powerglide

 

Which effectively will give you an 'overdrive' gear for every stock gear, so in the case of the 2-Speed Powerglide box you'll then have 1st, 1st-over, 2nd and 2nd-over - effectively giving you a 4-Speed high HP auto transmission as per Dude's description. Example of such a setup on the strip here:

I have a 4l80e box in my motorhome and none of the usual companies do any uprated parts for it, so I wonder just how 'built' that is, the box is also pretty complex and needs an ecu to control it.

[Inferno]

True, but SP have done their custom 4L80E setup in quite a few high powered spras, and while there may not be a lot of uprated parts locally to you, there are LOADS in the US (http://www.transmissioncenter.net/4l80e.htm) and SP can build it for you...

Now thats what im talking about, I will drop them a line and see what HP and Torque that thing can take, I can see my car being auto again by next year with a set of 4.11 gears for drag racing.
