antilag

[jangotat]

can anyone tell me what the most effective antilag method isÉ in your opinion that is. And to be truly effective it should work on all turbos including the ceramic ones otherwise its like a workaround. i was wondering if anyone thought that you could install a battery powered supercharger so to say that is in front of the turbos to provide initial boost. as you all must know a traditional supercharger is powered by the driveshaft and while there are some cars that have one of each, it would be extremely hard to install in an r32 chassis. http://www.superchargertuning.com/Nissan/Skyline/
this site says they have a supercharger that can provide upto 5psi of boost in less than a tenth of a second but since its electric it can only run for a minute at a stretch and therefore it only come on when you actually floor it. since turbos can take alot longer to spool up, would this help give you an even power band even with a big blowerÉ im almost positive that it would work the only question is once the turbos come on full blast, could he supercharger take the pressure without blowing itself to bits. its made of metal and is solid construction. what do you guys think

antilag= cool sound but blows your **** up! especially on weak r32 turbos

ECU controlled antilag only in my opinion. No external controllers.

Antilag creates extremely hot exhaust and it is very hard on turbos. Heat and shock are two of the biggest enemies of your stock turbos. Antilag when used correctly though can spool a turbo extremely fast, I set up a haltech ECU to spool 22psi with a 6262 in just a few seconds. Why waste your time with this electric mumbo jumbo.

Ask yourself this:

With a stock turbo, is it really necessary to have antilag anyway? We aren't talking about a laggy turbo here. I think you would be much much better off looking into a 2step/launch control.

There is the Rush Antilag system. A lot of Supra guys play around with it but the 2J and majority of their setups are no where near as fragile lol

How does the vipec launch control work ? That's what I'm running but not sure exactly how it works

Vipec also has antilag, not just launch control from what I recall.

If you really want anti lag, get an Evo X. Virtually no lag.

ok well the thing with antilag and two step is that it exploded fuel in the manifold to create the pressure to spool up the turbos the traditional way, that is by exhaust gases. what im suggesting is an electric fan that is powered by your car battery that is between te intake and the turbos that forces air in similar to a supercharger. when you floor it (turbos practically unspooled at idle), it spins up almost instantly, forcing air into the turbos that will get them to spool faster and therefore reduce turbolag. the electric fan can produce about 5psi to cover the bottom end of the rev range before the turbos spool up. then once they pass that pressure, they will be sucking the most air. do you guys understand what i meanÉ its different than traditional antilag. i think it would work as long as the turbos dont destroy the fan once they pass 5psi of pressure. i dont think they could though at most maybe burnout the electric motor since the motor is made of metal and if they wer capable of that wed be shredding our intake filters lol

[gtrjon]

okay lets get to the root of the problem lol. There is hardly any lag on stock turbos anyway so what are you trying to achieve?

[jangotat]

if it works then i could want to upgrade my turbos otherwise too much lag would even be worth it running it on my stock turbos until then

a bit of lag is fun.. it's telling it's ''cumming''. take some times... you heard the motor reving higher, uou know you floored the pedal.. you know a big suprise is coming and banggg where's the fun :P

I like this analogy lol

Best analogy so far lol. Also, stock turbos are fairly small twins, so there's virtually zero lag. If you were running bigger turbos (singles especially), then you might want to look into an anti-lag system, but for the stockers, it's not really worth it IMHO

If anyone on here needs anti-lag, it's me. But I don't need it. I can launch with full boost and need to really regulate the gas pedal to keep everything under control. The only time you need it is when you are starting from a dead stop. Everywhere else it is not used.

I rev to 6500, do a clutch rideout, and I have 20psi at 5000rpm in about 1.5 sec.....anyone with smaller turbos can do that at 2000 to 3000rpm less. Stockers, you can have full boost at 2000rpm if you use a Grainger valve at each regulator (wastegate) pot. Set them both for 10psi and you will spool up even faster than stock (which is pretty stinking fast).

Never heard of graigner valve before.

[Dragon Humper]

You can get them at Acklands/Grainger (hence the name), it's a pop-off valve used in pneumatic control systems for automated manufacturing equipment. It can be set at any pressure you want (up to about 30psi) and will hold back any pressure untill the check-ball gets cracked off it's seat. This keeps the waste-gate fully closed untill you reach your target boost, bringing boost pressure in a little faster. You put it inline with your waste-gate vacuum/pressure line and really works well, ran 20psi on my Omni using one and it came in like a hammer.

You do have to modify it a little, not much, you only need to press in a piece of 3/16 tube in the top, screw a 3/16 barb on the bottom and drill a 1/64" hole just above the check-ball to bleed off the pressure from the actuator after you are done laying the smackdown on someone.


Some high dollar boost controllers will do this already, a manual boost controller is the same thing but costs 5 times as much (I build mine for about $15). Stock doesn't do this at all, the actuators will see a small amount of pressure while you are building boost and crack the waste-gates open a little which slowes down boost building (sometimes a good thing). Pull the pill in the bleed line and add Grainger valves at you waste-gate actuators and you can have 14psi at 2500rpm (or less). Bottom end grunt that will need a chissle to get the smile off your face.
