For those interested in moving to a moderate/high boost multi port injection system, ive got 4 180cc nozzles and 90 degree fittings along with some other related stuff if interested. 150psi pump, solenoids etc. Even have a oem intake manifold that I ran thats tapped in each runner for the injection as well as TB opening ported for sos TB. Im not planning on being boosted again anytime soon so this stuff could be better spent on someones car then on my shelf.

Have you got a spare SOS TB Junky.

I want one of those

Did you have any MAP failures when using the SOS TB?

s2000Junky

No extra of those, just stock ones. I'm still using the same SOS TB NA these days. Never had any MAP failures injecting a ton of fluids through it, so its proven to me. Still works great with however many miles on it. Probably 100k or more now.

I've finally took the plunge and got a meth kit (AEM v2) after much debate, just need the SOS TB now.

Did you have any issue with corrosion on your CT AC or BOV?

s2000Junky

No, none that was perceivable to me for the duration I ran it. I think the key to long term reliability with no "corrosion" issues is to run a diluted mix with some amount of water. They say 50/50 for typical recommended mix, but I felt 75% meth was more efficient overall and better performing for my set up. Water doesn't burn, so you really have to make sure your system is optimized with proper spray amount and atomization to run higher concentrations of water.

The AEM v2 pump is rated up to 200psi, so my plan is to run the smallest nozzle and angle it back slightly via an angled boss that will be welding into my CT-AC (about 7inch before the TB).

I also plan on having the progressive control set at 10-20psi as I see 19.4psi at 9200 rpm. My AITs are stable up to about 10-12psi then they start to rise rapidly at the moment.

I've read that you didn't like the AEM controller because of lag, was yours a V2?.

Thoughts?

s2000Junky

The small nozzle is too small to offer anything for you. The Med 330cc nozzle should be used at minimum and I found the large 550cc nozzle about on point especially for your high boost application.

Yes the progressive controller was garbage. If its the same unit I had, throw it away and wire your system up to your engine management to be controlled non progressively /on/off nitro switching input for example. If your progressive controller responds as poorly as mine did, you wont get any injection set at 10psi until you get into 3+ gears where the engine spools up slower giving the controller a chance to read your pressure and start spooling up the pump. This makes the car impossible to tune around. Well I will just lower it to 5psi so it comes on at 10psi you say? Nope, then it comes on at 10psi in lower gears and 5psi in higher gears and again no way to adjust tune based on gear.

Sounds shite, really hope this isnt the case!

By its design I imagine you're right. I'll see what the logs say once installed. I'm only using it for cooling.

If only using it for cooling, a remap isn't required is it?...or is the the AFR effected by the meth?

s2000Junky

The afr is effected by meth absolutely. If you are not seeing a clear enrichment from your injection before re tune, then you aren't spraying enough to get any benefits. But keep in mind wile meth will offer cooling, its main purpose is raising oct for detonation suppressant for more boost or timing. Water is more effective at cooling, and this will not effect afr. You will be mixing them, so you should still see an afr drop. Running too small a nozzle and your getting very small "parts per" each being injected. So this is where a larger nozzle is recommended, just have to make sure your getting good spray and tuned for it.

I don't want to run anymore boost and don't need anymore power really. The stock trans already is struggling to cope and I've snapped more drive shafts than I can remember.

The only reason I want it is to reduce AIT's when on the track
