WOT Box + Turbo = "clutch boosting" ?

[JeremyH]

So finally broke down and got a wot box, thanks Tom!

I have read through the threads and the setups instructions and now I have a question/idea if you will.

So normaly from a roll with a turbo you can brake boost. Lightly press the the brake with your left foot as you roll into the gas to maintain your speed, build boost and then let off the brake and go wot under boost.

With a wot box can you "clutch boost"? lol Im guessing you could use either the no lift shift feature or 2-step feature to do this from a roll.

No lift shift feature set to auto: driving 55-60mph in 5th gear go wot then immediately push the clutch in, this will activate the no lift shit and start cutting timing. Instead of immediately shifting and letting out the clutch, downshift to the gear you want, lets just say 3rd gear. This hole time while you are holding down the gas, and the wot box is cutting timing you will be dumping fuel and building boost. Once you build the desired boost or your ready to go just let out the clutch. This can all be done in 2-3 seconds so you will be coasting maintaining your speed and waiting for those 3 honks

This would be even better than just downshifting with a turbo as you will actually be already in boost after the downshift.

Would this work? Anyone with a turbo/wot box tried it?

This could also work for the 2 step feature, say in 4th gear on the highway, going 55-60, let off the gas and push the clutch in to coast/idle, go wot to activate the 2 step, start building boost then clutch out to go.

What yall think? Am I or would this work?

I don't see that happenin but give it a shot and let us know lol.

I think the problem you'll have is that the no-lift-shift is only for a limited time frame(something like a 1/2 second), and also I think it completely cuts the ignition and doesn't work like the 2-step.

 

[Tom]

On the WOT box the window for the wide open shift can be changed(meaning how many mili secs you have to actually shift). All boxes come with a pre set time window. The WOT function can also be turned off as well, very easily I will add.

As for the 2 step, its functions mimic the WOT shift feature, meaning it can also be set.

As for brake boosting from a roll, the breaking would be the main factor in building the boost.

As for the OP's idea, It could work depending on how long you set the WOT feature too. However I would be careful because if you are using the WOT to long, you could easily foul the plugs while WOT box is actually cutting fuel.

Interesting idea though, def keep us posted on your findings.

Thanks again,
Tom

Yeah im not sure either, figured someone would have tried this already, just one of things that dawned on me and i started thinking about it lol

I think the problem you'll have is that the no-lift-shift is only for a limited time frame(something like a 1/2 second), and also I think it completely cuts the ignition and doesn't work like the 2-step.

Per the instructions when the no lift shift feature is set to auto, it engages when you clutch in and disengages when you clutch out so its based off the clutch position sensor. Cutting ignition is fine its the fuel that spools the turbo. Or am i reading it wrong on how the auto feature works?

On the WOT box the window for the wide open shift can be changed(meaning how many mili secs you have to actually shift). All boxes come with a pre set time window. The WOT function can also be turned off as well, very easily I will add.

Yeah im not sure either, i mean if you can sit at the line and build boost, you should be able to do it rolling too, i think lol

I am def gonna check it out and see if its works, or is even worth doing, just wondering if anyone has heard of this yet or tried it.

Great..the mad scientist at work again!

Gotta love creative engineering!

 

[JeremyH]

Haha, i dont even know where these ideas come from sometimes, boredom at work mostly.

 

[fdjizm]

Probably the only way to build boost while rolling is using the two step while rolling but you need it set high i guess? you can use the two step at any speed. I blasted a ricer with mine set at 5000 sounds nuts

 

[JeremyH]

Thats good to hear, i mean i figured the 2 step should work since it doesn matter if you are sitting or rolling. For you n/a its basicly like a safer way to double clutch or just stab the clutch in realy quick to raise rpms then let out to get going faster which i have done n/a many times. LIke for when your caught off gaurd after a shift and need to get moving quick without downshiftting. 1st and 2nd gear double clutchs are nasty, really gets the car moving. lol

I really wouldnt need it set high, its not the rpm that spools it, its the hot fuel in the exhuast thats gonna spool the turbo.

I have recently learned that some racers have been putting small 25 shot of nitrous into the turbo housing or right before it to help spool as well, nuts.

Im not sure about the no lift shift method at this point either, but hey its worth a shot i guess, both methods can be done fairly quickly while driving even if it only builds 2-3 lbs of boost in 1-2 seconds, thats better than no boost when roll racing.

yea I think the rolling two-step idea will work out well for you, and so should the no lift shifting, the exhaust doesn't slow down for that millisecond that much I think the more important part is that the throttle blade is not closing at all instead of closing for a sec while you shift then opening up.

 

[dysan]

From the manufacturer's site it says the maximum no-lift shift is 350ms.

Programming

The WOT Box version 2.1 and up comes preset for an automatic WOT Shift kill time. This means that the WOT Box will automatically adjust the kill time to your shift time, up to a maximum of 350 ms

And it looks like the max you can set it manually for is 550ms in the chart below that.

Thanks dysan, so looks like no lift shift feature wont have enought time to build boost, just maintain it during quick shifts.

Time to focus on the rolling 2-step lol

 

[fdjizm]

From the manufacturer's site it says the maximum no-lift shift is 350ms.

yea 350ms will not be enough to get a decent spool.

Yeah the throttle not closing keeps the bov from activating which maintains full boost during the shift. This wot box is going to work out perfectly with the trubo!

 

[dysan]

Be sure to take some videos when you try out the wotbox with your turbo. Have you swapped in your billet one yet?

 

[JeremyH]

Will do Ive been meaning to do some turbo vids of different stuff anyway, nah the billets not on yet, hopefully go on at the end of the week or next, got a find time to do it as there are a few other things i need to do at the same time, should be a good days work. Wot box shipped out today.

 

[JeremyH]

Thats kinda catchy too, so should i call this clutch boosting or the rolling 2-step lol

 

[dysan]

Heh...or rolling on the clutch boosted 2-step!

 

[JeremyH]

LOL

 

[fdjizm]

two step rollin' yo.
don't forget the yo.
