Tommyd16 Posted September 24, 2014 Share Posted September 24, 2014 I would ideally like my supra running 500bhp. I've read this is top end for the autobox. I was thinking a small single for fast spool and reliability making it a good fast road car. Is this an option? Or is 500bhp and a small single on a autobox abit of a dream?

safcdixon Posted September 24, 2014 Share Posted September 24, 2014 The top end for the auto is around 600 with a couple of autobox oil coolers, with the torque capped im sure there some members on here thats ran over that number Quote Link to comment Share on other sites More sharing options...
mellonman Posted September 24, 2014 Share Posted September 24, 2014 I have been running my single turbo TT auto for a few years now 525bhp @510 ftlb . TT vs N/A auto are different have a lok through this group that David P made its very informative http://www.mkiv.co.uk/vbb/group.php?groupid=57 Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted September 24, 2014 Share Posted September 24, 2014 Its not so much bhp you've got to worry about, its torque and heat that kills an autobox. There are a few things you can do though to prolong the length of the stock autobox. You can fit a couple of transmission coolers which will cool the gearbox fluid. Also if you are going to be running a Syvecs, you can have the torque limited during the gearchanges to take the pressure of the box and then the torque will be fed back in when the gearchange is complete. Regarding power, my dad had 607bhp and 560lbft on a stock auto controlled by a Syvecs and the stock box lasted just over a year. If your budget would stretch to a built auto such as a Boostlogic, Titan, SRD built box then I'd highly recommend that option. Quote Link to comment Share on other sites More sharing options...
Tommyd16 Posted September 24, 2014 Author Share Posted September 24, 2014 Awesome. Best start saving for a single then! What supporting mods are you running mellonman? Quote Link to comment Share on other sites More sharing options...
mellonman Posted September 24, 2014 Share Posted September 24, 2014 Awesome. Best start saving for a single then! What supporting mods are you running mellonman? what for the auto box or all in ? Auto box I have 2 large transmission oil coolers while retaining the toyota radiator core cooler/heater keeping the radiator cooler/heat is just as important for the life of the trans as cold oil can also cause damage , Quote Link to comment Share on other sites More sharing options...

mellonman Posted September 24, 2014 Share Posted September 24, 2014 well depends on how big you budget is but I have :- AEM FIC 8 piggy back ecu 630cc injectors 400lph fuel pump + fuel pump ecu relay mod pulsation dumpener bypass fuel preasure regulator top feed fuel rail that match injectors AEM wide band o2 sensor T6765 .68 dbb turbo mainfold hks wastegate hks intercooler + piping apexi avcr boost controler apexi adjustable BOV 3" down and mid pipe 3.5 " cat back exhaust K&N air filter + piping idle control valve filter turbo blanket oil lines water line breather pipes with catch can heat wrap for exhaust I think that all but when doing a single build there are so many little bits and bob's you forget or didnt even realise you have to do Quote Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted September 24, 2014 Share Posted September 24, 2014 i was running 558bhp on stock box for loads of time! not problem i then went on big twins running over 650bhp for ages on stock autobox! Quote Link to comment Share on other sites More sharing options...
Kaan W Posted September 24, 2014 Share Posted September 24, 2014 Mine lasted until the next day after I bought the car at 580bhp, then.sourced another low mileage one which last 5 weeks. I suppose it's how often, how long and how hard you wish to drive. A built auto is a must for a small single imo, but it's worth using the stock box with some coolers until you go built.

Rob_Mitchell Posted September 24, 2014 Share Posted September 24, 2014 should last long as you will obviously stick to the national speed limit? you just get up to speed a bit faster than the average car......lots of tyre smoke, noise, and rear wheels take up the lane next to you Quote Link to comment Share on other sites More sharing options...
thetrashcanman Posted September 24, 2014 Share Posted September 24, 2014 (edited) i was running 558bhp on stock box for loads of time! not problem i then went on big twins running over 650bhp for ages on stock autobox! Yes but you drove it like a girl Rob Re the ops question although it's basically been answered a couple of oil coolers for the autobox and a syvecs so Ryan can cap the torque Edited September 24, 2014 by thetrashcanman (see edit history) Quote Link to comment Share on other sites More sharing options...

Tommyd16 Posted September 24, 2014 Author Share Posted September 24, 2014 Really want a single now! I'm full BPU already with FMIC and have an oil cooler for the autobox already - just not fitted yet. Have been looking at this kit.
