Does it look like I will have enough room for the compressor outlet to be clocked low?

Alsooooo do you think I will need to use an elbow to get a big enough air filter in there?

 

**** me I wish my Vbands were grooved. That smooth **** doesn't line up to save my life.

 

Abe what company v bands are you using? I am using the vibrant 3 inch ones on my new exhaust and they have grooves and a groove to fit the 3 inch tubing into. Theyre pretty sweet.

 

The grooves are certainly nice but I think the best feature of the vibrant vband package is the quick release clamp. I haven't seen another brand that has that. IMHO well worth the 3-4x price tag.

 

fancy vbands are nice.

OBX sells those, its kind of amazing to get them at a good price. those ones line up so well and never leak.

 

Results from my fifth WI nozzle.

Again, this nozzle is at the IC exit. It is 1mm. The other four are direct port and .4mm.

The purpose of putting it there was to cool the charge and also to have it before the AIT sensor for accurate air temp trims.

It worked. Without WI, on a 25psi pull to redline I see a 15-20* rise in air temps. With WI, I now see a 5-10* rise in air temps. Yay.

On the downside, I think I have a coil that is dying or cripppled. Regardless of dwell I am getting some breakup. I'll try changing the plugs today for the **** of it but I fear coil death. Plan is to do a pull and as soon as it start to break up, shut car off and pull over. Hopefully one plug will be wet or something.

 

Are you sure its not just cooling the body of the sensor so there is no heatsoak on it anymore?


injecting that much water is outrageous and debateably inefficient because of the mass volume!

 

My air temp sensor bulb stands free in the charge air. It does not heatsoak anymore. As soon as I lift off the throttle temps drop back down again in the logs.

For the washer fluid I'm spraying now, you're supposed to spray around 15% mix to 85% fuel. Pure meth is supposed to be around 20%. That's a lot of juice. I haven't done the math but have kept adding water until I saw a point difference in AFR. Then I leaned it up.

 

You should put fuel in your WI system and water in your gas tank. Then datalog.

 

I recently broke one of those fancy quick release clamps.

It involved a sledge hammer :(

it's fine now.

 

User error.

 

Ok tuning bitches.

Who here is familiar with rich knock?

 

Why Faeflora, I am indeed familiar with rich knock. Rich knock is indicated in logs by sustained higher levels of knock sensor voltage (noise). Lean knock AKA detonation is indicated by spikes in knock sensor voltage.


As I mentioned before, I was also having some crappy breakup issue which I was attributing to dwell or the coils. I had another box of plugs (FM's resistorless NGKs) and so I swapped them in. While taking out the old ones, I saw that one of the plugs was covered with sludge. Earlier this week, I poured about half a quart of oil into my spark plug well. I guess it went down there. When I started the car up with the new (and clean plugs) everything was so much better. More stable AFR at idle, and clean AFRs in my boost logs. Yay, plugs to the rescue.

With the new functioning plugs I redid my WI I did the math and I was actually spraying quite a bit more juice than I needed to. I was seeing rich knock and upon removing some water, I saw less noise on the knock sensor. Joy was had at 23psi. Much much much joy. High boost is at times, as good as sex. I then upped boost to 25psi and had sadness for there was a continual 6000RPM ping (knock spike) which I had trouble tuning out. Anyways, ****'s fast nig but I still can't wait for my new setup.

Oh btw, as I mentioned before, the 5th nozzle really does work very well for reducing AITs. Big intercooler **** off and die.

 

How size nozzles are you using? What's your timing at 6K+ at 23#?

 

I am extremely curious as to why you did this, it seems like a rather bad idea. But then again I don't know jack **** about engine tuning or your turbo witchcraft.

 

I think he did it in an attempt to counteract stoichiometric knock.

 

You guys. Such jokers.

Downpipe mostly done! And yes that is 3.5" swelling to 4"





Dump tube is in the works.

 

4x .4mm nozzles for direct port
1x 1mm nozzle on the IC outlet

Timing @ 6000RPM @23psi was 15* after WI trim. I dropped it to 14* after WI trim and all was fine. I also took out a "mound" in the 3D WI map around 6000RPM which may have been causing a misfire.

I drove it hard tonight in the cold air and all was good.

 

Have you thought about running more timing?

 

Well I would love to run more timing if it doesn't detonate
