whereto inject Alky on HA car?

[sully442]

I put the Alky kit on. I am bogging the car down even with a little Alky. I got it under the turbo to of plenum. Seems to be it is not mixing. I was thinking on moving it back. Cutting hole in 6 inches behind MAF. What has been best for the cars who have done kits?

Thanks

Ok I am in the intake adapter now.It had a threaded hole, seemed to be to easy. The car bogs hard even with a small amount of Alky. Does good with kit off,but I can't realy run that way for long (to lean with TT chip). I am thinking to move the injector pre turbo. I saw the posts about it seemed like it was 50/50 on results. Any other ideas to try befoe I move injector?

I would change the Alky "turn on" and "initial" setting before moving the nozzle. This assumes you have the Razor Kit. Brad

 

[sully442]

Brad, Yes I have the Razor kit. I will that first. I just bought headers for it also. So I can mess with the settings before the turbo comes off for header install.

Thanks

^ why would you take the turbo off to install headers????

As for the bogging.. Whats the 02 voltage @ when its bogging?

I wouldn't change anything just yet. we need to figure out whats going on.. what kind of tunning device are you using? let see some data so we can tell you what you need to do

 

[sully442]

Boost, I would be pulling exhaust off the turbo. It would be an easier time to pull turbo if i need to move Alky. I will leave it there and see what we can figure out first. I got my scanmaster working. I will take some o2 readings and post them. when it stops raining.

leave the nozzle in the adapter there is not reason to move it.. can you post a pic of where you put the nozzle in the adapter. make sure its in the very back. if not you will not get even flow to all 6 cylinders. lets say you have the nozzle on the passenger side shooting towards drivers side. you will get more alky on the drivers side and less on the passenger side and thats a big no no..

my alky is mounted on what you'd call the neck of the intake, right below the adaptor drilled into the intake, only do this with it off. heres some picks for your reference.

Those pics are looking down from the backside of the turbo and its before I hooked up the line.

 

[sully442]

I just got a closer look. I got a few PICS,bad spot for pics. It is in plenum just below where turbo mounts. t

This is dead on correct. Center of the turbo adapter closest to the firewall. This is the only place to get even distribution of the methanol through the intake manifold. Spraying before the turbo makes no sense what so ever. The purpose is to cool the charge which can only happen after the turbo compressers the air which creates the heat. brad

 

[sully442]

Ok good to know. I will keep looking. Glad I can leave that part alone. Next move is 02 readings when it bogs out.

 

[crashedout1]

do you have any ex leaks

 

[sully442]

Not that I noticed, I will double check to be sure.

Well the debate continues.:biggrin: The TB community is a firm believer in putting the alky after the turbo but I will point out that the original HA cars run it before the turbo. I've done a lot of research on it myself and all of the data says that putting the nozzle 12 inches before the turbo is the best location for atomization of the alky. A fine stream properly shot at the center of the inducer wheel won't "erode" the inducer wheel, like is clamed frequently, and cools the charge as it's being compressed so it's a win-win.:biggrin:

I prefer the think that methanol sprayed at pre compressor speeds will vaporize very slowly compared to the outlet speed of the turbo compressor. Will meth vaporized quicker at ambient temperature at pre compressor speeds or very hot 200 mph speeds after the turbo compressor? IMO-I will put my money on the latter any day. Whatever works.

Took a little to find it but here you go Brad.:biggrin:
