I just finished making mine last night, only costed me $24. I used air compressor hose, anyone think thats too soft? I'll try it out when I figure out where im going to mount this thing.

 

That will probably be fine. Let us know how it works

 

wow! this thing really works! I've been detonating all this time, right around 6000-7000rpm, this is my area of peak fuel consumption too.

SOHC_MShue, how did you route the hose through the firewall? I had mine coming out of the back of the hood and through the driver side window. The problem I had with this is the hood was pinching the hose.

I ran mine through a hole in the firewall. I believe it was where cruise control went. How much timing are you running in that area? I found that I had been detonating all this time as well with 1deg/psi of timing pulled out and 11.5:1 afr's! I actually no joke had to pull about 5* after vtec crossover to keep it from pinging. I'd like to see other people try this out and see if they are picking up light detonation

Tell me about it.. every time I talk to him (pretty frequently), I get a new perspective on everything that I was considering. Dave's a VERY theory based guy, and can explain how everything works, and why it works. I've never heard someone talk sooo technically about water injection (over a 2am dinner a waffle house haha).. he really thinks EVERYTHING through.

 

It seems allot of guys will find they have been using too much timing.

This is going to impact the aftermarket pistons company since less people are going to blow their engines.

i'm running 20* in this area with 11.5 afr's. I'll probably retune it again tomorrow. I'll probably run timing numbers like these...

5k-6k rpm - 19*
6k-7k rpm - 17*
7k-8k rpm - 19-20*

...but i'll let you know what the final numbers are.

 

Soft walled hose is going to, at some level and to some extent, dampen vibrations/sound. But, since you guys seem to be hearing things pretty well, it's probably not significant. I'd just recommend varying hose lengths to see if sound properties change noticeably, try to get a feel for the system.

Fuel follows torque, and peak torque is where peak cylinder filling and combustion pressure occurs... it is also where detonation is most likely to happen. Your AFRs look good, and your idea of drawing out a few degrees fo timing where det occurs is solid. Frankly, if the det is really pronounced, you can pull more than 2-3 degrees without losing significant power..


6-7K peak torque, eh? IM me your setup, please?

Yeah, that's one of our favorite conversations. That, and manifold dynamics (30 minutes ago). And alcohol. And women. Did I mention that he came down for the weekend a month and a half ago, and within 15 minutes of meeting my (female) roomate he almost had his dick in her? The boy is a pimp and a scholar!

 

Yea man let me know. Just to let you guys know exactly how conservative my timing needed to be to make the pinging go away completely....i am running about 12* total timing at 12psi. I had to pull the most timing out around vtec crossover though. I suspect it could possibly have something to do with the location of my iat sensor in the charge pipe rather than in the intake manifold. This causes it to read much lower temps than the obd1 ecu code is used to seeing so i'm guessing that could be doing something with the timing. I would think it would retard timing though due to having a denser charge so who knows.

 

You seen Crome's new setup, where you can manipulate fuel and ignition based on IAT?

Yea i've seen it. I've been meaning to tune my car on crome, but right now its running uberdata. Between classes and tuning other cars I have no time to tune my own car espescially since it takes forever with me swerving all over the road and trying to adjust values on the computer while driving . I have cromepro though so I really need to throw down a quick tune and check to see what the actual timing output is with datalogs.

 

wow, this thread is amazing, the start of something that seems really big, im in it to LURK!!

here's a dyno graph of my street tune...this is with my timing completely untouched, just on a step-retard. I have advanced my timing a lot since. If I ever get tune my car on a dyno I could probably get peak torque to come in a little earlier.

Setup:
t3/to4e 63ar .57trim
revhard turbo manifold
aebs intake manifold
2.5inch downpipe
2.25inch exhaust w/ no muffler

 

curse this michigan weather, anyone get a chance to try it wiht a computer yet? I can't wait to get out and try this out.

 

I finally got a chance to try the det can out...its a stock block b16 on 9psi(3rd line up from the bottom)
...I went from this...


...to this...


...im probably going to need to retard it even more from 7500rpm up, I still hear a little detonation there.

holy **** looks like you had to pull about as much as me.

 

Crazy, you're still making good torque at 7K. Was there any boost creep to speak of during that dyno pull?

 

so anyone know of a good spot to hook one of these up on a b series block with power steering?

Lol the anti-lazy, go try!

 

Yea i'm thinking I can pretty much hook it anywhere on the engine because even with mine put on the block where it is now I can still hear the bov and noise from my broken tranny pretty well.

 

bump it up. I wanna see other people testing this stuff

 

Well I tried it. About $20 CDN in parts so far into it and I have enough hose and tubing to make another one. I gotta say, it works GREAT. I just need some way to hook it up to the ears 'cause driving a manual, shifting, and holding a tube in your ear just isn't easy.

from me!

 

bwahahaha i tuned by holding the tube to my ear at first too before i got the headphones all hooked up

We've gotta hook one up on my new D15

 

hahahaha I knew you would try to turbo that thing
