Any plans of removing the intercooler all together?

 

There are advantages to running water. I would go with a MUCH larger tank. Something in the 3-5 gallon range if you are running pure meth, with no intercooler. Also, be careful with that tank. Do you have a level sensor in it? Did you move where the feed line draws from? There are several disadvantages to its design...I am sure they can be remedied though.

Heck...I would go through a 1.5 gallon tank on my setup in about a tank of gas. And that is with pure water, which requires substantially less volume.

 

Awesome results, not running a intercooler on my setup either. So, I'm anxious to try this out.

 

nice man **** Viking!! LOL

Cosmo, We did remedy the pick up location and I am working on getting all my warning lights functioning and installed. I JUST got the results I've wanted, so now that I am finally through with the "testing" phase, I can complete the system.

I may run a 80/20 mix again, but for now, I'll finish off this tank. This tank isn't terrible, especailly the way I drive. It fits nicely into my bin and gives me a place to mount the pump. I am pretty light on the throttle. I don't really hot-rod around unless tuning or racing.

 

hey stylemon where u get the SS line made and how much?

 

Turblown did it. I don't have a cost break down in front of me right now, but the site is Turblown.net or pm here (1revvin7)

The AI system generally wasn't crazy expensive. 3-400 I think.

 

How's this holding up ? How's your intake temps ?

 

I've been driving REAL light lately. The car has taken a back seat to some family issues. I still drive it often, but I have not boosted in about 3 weeks.... I know, sad.

I was seeing REALLY good temps last time I tuned. I am unsure of the exact temp; It was in C and it was a few weeks ago...

What I do remeber is, the AIT started out slightly above ambient. somewhere around 110*F. When it started sparying, the AIT started going down quickly! And the more/longer I boosted, the lower they went. That was the coolest part.

This was with 100% Methanol

 

Still a pre turbo setup, right?

 

I got one pre and one post.
we did a BUNCH of test, and the pre compressor jet makes ALL the difference. (especially once it was hooked up to the big 150psi pump.

So I have a large jet post and a smaller one pre.

 

So, you have those two jets on the same pump ?

Weren't people talking about how dangerous running pre-turbo was because it will damage the comp wheel ? What was that all about ?

 

I have two jets off the same pump.
It is true that alcohol will eat up a compressor blade, water will too. But at what rate? The way I drive, I may be looking at replacing the compressor blade every 4-5 years. That's just an estimate and I have yet to see ANY damage.

If I had a huge jet, spraying all the time, yes it may be an problem, but I have a small jet pre-comp. I dont think there is anything dangerous about it tho.

 

Alright, so what jet would you recommend pre and after ?

 

I'll be honest, I know little to nothing about the actual jet sizes. Elliott at Turblown had all the jets lined up when we did the testing. So he's the one to ask about that. I understand the general concept behind AI. I know the difference in the effects of water and alcohol. And I know how it runs through the MoTeC... but as for all the specs, that's where a good shop comes in.

 

The Devil's Own pump will run into the 200 psi range with a single small nozzle. There is a long thread at aquamist.co.uk about pre-turbo, and Dvldoc has quite a few turbo diesels running pre and post turbo with good results. As long as you keep the pressure up and the microns low, there shouldn't be much of a problem.

 

Sorry, found the info, but can't edit my post

M2 230psi
M3 225psi
M4 215psi
M5 190psi
M7 180psi
M10 170psi
M14 155 psi

 

I beleive I have a M2 pre and a M10 (maybe 7) post.

 

Just went out tuning and logging. I did a real nice 4th gear pull and saw 13psi with 78* intake temps!
will post log soon.

 

i thought ya'll might enjoy this log.

Here is a 4th gear pull from about 3000 to 6000 RPMs. I have a 9psi wastegate spring, but you can see, in 4th, it gets up to about 12 psi. The car is tuned for that range, so it isn't a big deal... The turbo is just letting me know it wants to be opened up some more!!

The outside temp was around 70*F. I am running 50/50 water/methanol. It's great to see the AIT drop under boost like that.

 

Still doing no-IC or got plans for it? Sorry, pseudo-old thread and I'm a pseudo-old guy that doesn't keep up with it. I hope it's hot air as it'll give me more motivation to get off my lazy butt and get it done on my red car. I'm anxious myself to try it out w/ all the alcohol I use. I mean, come on. How well is the actual stock top mounted IC really working ya know?

B

 

No IC.
The stock top mount was making things hot even with AI. I saw a huge drop in temps when I ditched that old inter-heater!

I keep wanting to go with a VM or FM just for insurance... But I know there will be a rise in temps, plus a loss of boost.

I am wiring some safegaurds in my AI system now.

 

Very cool. I need to get on it on mine. My red car is rotting in the driveway right now; haven't driven it in a few months even though I was on the edge of finishing tuning this latest hardware iteration (got back up to 21lbs on the T70 .96 A/R setup with the stock TMIC and 65/35 fuel/alcohol ratio). Tell me to get off my lazy butt.

stylEmon, I am planning on running a 25/75 water/meth combo, mainly because my alky setup isnt able to run pure meth, I figure with some water in there itll keep the pump alive for long enough. Did you find any reason NOT to run a mix of water?

 

water is a MUCH better detonation deterrent... it's nice to have that in there.

I have seen way lower AITs with pure methanol, but the little extra measure is worth it IMO. I will definitely be raising the mix to 75 or 80% methanol

Weird, sometimes this shows up and sometimes it doesn't. I'll just attach it here.

 

Get off your lazy butt!!
Na, I hear you've been busy tuning and such. I talked to TweakGames and he seems happy with what you're doing.

21 lbs is pretty nice!! I want to start up'ing my boost now that I am seeing temps/tuning that I like.
