Also, everyone keeps talking about Evo's using antilag. Lets keep in mind they are AWD, and Z's are RWD..... if you launch a Z like an Evo, you will just get instant spin.

 

I agree Hal, no one here has the need for a setup like that. TA or Rally on huge turbos for small engines with tight turns is where this setup helps alot.

There's absolutely no reason for a street car to have an anti-lag system. It completely destroys the life of your turbo.

I do realize this, cause I generally run street tires and I spun before I had the turbo, I'm just trying to learn as much as possible.

Now is there anyway to retard the timing right after launch once the tires grab and still have full boost waiting.

My problem is that generrally I get beat by the corvettes out there becuase of the throttle response. If I had the turbo spooled sooner I'd be able to beat them. So I launch, spin for a second, the tires grab, wait for another second for the boost to kick in and now the vette is a car or two ahead of me and I just sit on his a$$ until the finish line.

 

Builds alittle boost? My friends supra builds 20psi using the 2-step. Its all about how aggresive you have it set up.

Honestly, it sounds like this could be worked out with a little more seat time and changing up your launching strategy. For starters, try using the clutch enough to keep the tires right on the verge of traction and the revs high enough that if you release it all the way it would spin rather than bog.

 

But if you do it that way it won't ever really be a consistent launch. Using a computer to do everything it will be a very consistant launch and I can adjust other things to improve the launch. And like I said I really don't race a whole lot so I'm not good enough to be consiistant on my own.

Now heres the next question. I'm just learning how to tune, would I be able to try this on my own setup with out destroying something. I would imagine I could considering that I'd be retarding the timing. Could I just take the good working tune I have and just retard the timing at launch to see what works.

 

any way you look at it, the TN kit isnt the right setup to be trying any of this.


two step might help if you are launching cause it will allow you to create load, BUT the turbo is toooooooo far from the heads to have any kind of anti lag help.


you have to fully understand what is happening and why before you go messing up your setup..

 

I did think about that, thats why I said what turbo kit I have. I'm pretty sure I understand how this works but just trying to see if it can be done. Is the turbo on the TN kit too far from the manifold to be doing this.

 

yes, the whole reason it works is the turbo is right off the heads for the most part. it actually lets the unburned fuel into the turbo. there is about 6 feet of piping from passenger head to the turbo, maybe more.



if you are trying to improve your streetability/spool time up, add an open dump, and turn the boost up, then learn how to brake boost a bit.

 

I am getting an open dump in about a week here but I can't brake boost, I need to get that module that IO think kp was making or made. Havn't heard if it works. Or disconnect the brake light which isn't gonna work for street use. This would work with a greddy or aps setup though. Thats my next change so I'll have to play with it then. Hopefully I'll know more about it aswell.
