Discovery of the Nitrous / Methanol Drag Turbo Anti Lag System

[badopinion]

Doesn't seem to launch on boost..... maybe it's just me.

[DonW21G]

@badopinion First time, conservative test of a new tuneup, as explained in the video. Need I say more?

[DonW21G]

Are we really comparing a Buick Grand National to a Honda Accord? Good grief.

[AOGDC10]

Absolutely awesome concept!!!! Leave it to a Buick GN drag guy to figure out how to spool a giant turbo... you guys do it like brain surgeons. I've always wondered what venting the BOV to the turbine inlet would do with a rich spike & throttle closed? Would such a thing work? It wouldn't do a damn thing for a drag launch. Would it cause a crazy flow-stall? Such a thing might be very critical on cam setup.

[SkylineR034]

finally.. all i wanted to hear was a decent turbo before i slept and now that i have i happy, so thanks!

[elewsive]

you spent money on fixing up a buick LOL!!!! oh man

[AOGDC10]

@elewsive It's a 1987 Buick Grand National. Don't you remember 1987 when all other cars were shit?

[elewsive]

@AOGDC10 alright my bad ill need to go find that 1984 honda accord and see if i can strap a back to the future rocket on it :-)

[S1LENTJOK3R123]

Cool car

[ThySyN]

Gorgeous car.

[bossplayah05]

If there's any Aussies here the motor is the same as our vn-vy lol

[DonW21G]

@bossplayah05 Wrong by a long shot.

[GE24Tony]

what car is that?

[DonW21G]

@GE24Tony 1984 BUICK Grand National

[watchthisrobotmove]

@DonW21G beautiful! my dad had one and we change the single turbo setup to a twin turbo setup! spools at 2800rpm and on 25 psi.. the engine was a swap to the 350 ci roller rocker.. it was quite the beast..he ended up sellin the black beauty for 7000

[effyportable]

this is heaven

[hamrhed421]

why not drill and tap the hot side of the turbo and hit that with n2 from a nozzel? would that not instantly spool up the turbo?

[DonW21G]

@hamrhed421 See my newer videos entitled 'Turbo Nitrous/Methanol Anti-lag System with Afterburner Augmentation' and 'The Ultimate Turbo Anti-lag System'.

[Skyfighter89]

how much litre do you need on 100km ?

[DonW21G]

@Skyfighter89 I don't understand the question.

[Skyfighter89]

@DonW21G sorry for my bad english. I mean how much fuel this car needs.

[DonW21G]

@Skyfighter89 At this point in time, we are at around 240 lbs/hr/cyl with methanol, not counting the nitrous system. 1,440 lbs/hr for all 6 cylinders. This year, we're upgrading the fuel system to supply more.

[yagam1]

yeah damage the gearbox more mate . although i noe its a strong gearbox .

[DonW21G]

@yagam1 As of 12/2010, still on the same gearbox and torque converter. Fluid smells like brand new.

[yagam1]

haha ok . was juz kiddin though .

[Theturbo6guy]

@DonW21G very nice setup, you've got a good method of reducing lag, just more fine tuning im guessing right?

either way, badass gn!!

[DonW21G]

@Theturbo6guy

Yep. Always trying to squeeze all I can out of her.

[Tharosa1942]

isnt that a Grand National?

[DonW21G]

@Tharosa1942

Yes it is.

[Theturbo6guy]

@DonW21G what numbers does she make? stage 2? 109?

[DonW21G]

I'll get some new video posted soon. This is awesome.

[DonW21G]

I've finished developing the afterburner to the nitrous/methanol DT ALS system. HOLY COW. The results have turned out to be more than I could ever have hoped for. The two systems working together is now resulting in more than enough power for the launch. This new development has brought the whole powertrain, turbo, torque converter combination into perfect focus, with minor adjustment easily obtainable.

[DonW21G]

New plans are to design and install an afterburner to the ALS.

[DonW21G]

I've created a new video showing the car making a pass on the Barona 1/8 mile track. We currently got the 60 foot down to a 1.35. The target is hopefully a 1.30.

We're still in the testing and fine tuning stages with the new anti-lag system and have yet to push the limitations of the engine and car.

Check the video responses.

[thewakz]

v6 right? wowwowowowowowow neat sound

[DonW21G]

A shot size limit has been realized. Along with a new, more appropriately stalled torque converter, the new elapsed time from transbrake release to 179 kPa is now 1.3 seconds. I'll be putting together an updated video soon.

[DonW21G]

The size of the nitrous shot has been stepped up since the time of this video. Preliminary tests look very promising.

[DonW21G]

STAGEIIGN is absolutely correct. With the right combination, nitrous oxide injection is not necessary. Although, if one chooses to add nitrous oxide injection to his tuning tool box, it opens up a whole new world of choices for putting together new and different turbo/engine combinations. Combinations that, without the help of nitrous, would be completely unsuccessful.

[STAGEIIGN]

Guys go 7's and 8's without N20 in theit TB's. There is absolutely NO need for nitrous.

[DonW21G]

I'll see what I can do.

[DonW21G]

So far, so good. Using CO2 for the control pressure, you can pretty much tune any sort of boost curve you want. In my case, I needed a leveling of the boost rise for the 1-2 shift and today I worked out the control pressure curve by the 3rd pass.

[DonW21G]

I was using an MSBC-1. Within the past year, I've switched to an AMS1000. I'm concentrating on getting the launch squared away first. After I have the launch at a point that I'm happy with, I can finalize a boost control curve.

[DonW21G]

No. Presently, I'm shutting the nitrous down at 16 psi boost. I may lower it since, now with the boost building quicker, it may be hard to control the boost level for a sane 1-2 shift.

[DonW21G]

Don't make the mistake of thinking that this is just simple nitrous injection. With just preliminary testing up to this point, the advantage of this tuning strategy over simple nitrous/methanol injection is worth .2 sec off the 60 foot time. That is HUGE!

[DonW21G]

How this system works is by basically moving excess nitrous and methanol into the exhaust system, and with just the right amount of ignition retard, lighting the mixture off in the exhaust system. The amount of ignition retard needed to accomplish this is not nearly as extreme as other gasoline style anti lag systems. With less needed ignition retard to light this system off, there is less power loss during the starting phase of the system activation.

[DonW21G]

The oxygen needed to sustain this reaction in the exhaust system is supplied by the nitrous and methanol molecules. Nitrous being 30% oxygen, and methanol being 50% oxygen.

[DonW21G]

The nitrous to methanol ratio required to accomplish this reaction with successful results is a bit touchy.

[DonW21G]

Thanks for the insight. It may be something to explore at a later time.

I'm trying to figure out a system that will get me on top of the turbo as quickly as possible, without torturing the torque converter. I'm an old tranny tech, and it makes me cringe when I see these guys spending mega time to spool their turbo at the line. People don't realize how quickly heat builds in the TC when stalled like that.

[DonW21G]

Is what you're referencing any different than adding fuel, dropping cylinders, and retarding timing at a chosen rpm?

[theraf8100]

where does a 224 CI engine come from anyway?

[DonW21G]

A destroked Buick 231 V6.

3.937" x 3.06" instead of 3.80" x 3.40".

[theraf8100]

Wow...haven't really heard of destroking a 231...what made you go with that game plan?

[DonW21G]

The heads I originally bought for the project were ported, but reported poor flow numbers. I used the stroke to make the best use of the heads. I targeted a certain Intake port flow velocity.

There are better aftermarket heads these days.

[DonW21G]

Obviously, you've never tried to spool an Airwerks S510/91mm on a 224cid V6 on alcohol, with a 2400-2900 rpm stall TC before. No special ECU anti lag settings to make this work. Any ECU that will supply exceptional ignition energy can be used.

[red97m3turbo]

HELL YA!!!!!!!!!!!!
