14-psi tune update .. followup.

[StealBlueSHO]

I think you are fine....No need to tap your mani...You are a bit further downstream than most but I don't think it's bad because that probably gives it time to mix more evenly in the air charge.

I would be worried about loosing effectiveness due to the noisemaker... it's a big hollow piece of plastic made for air to travel through to make noise... I bet you take off the noisemaker after a pull and it's wet... through and through.

Just put a plug in place of that noisemaker.  $3.99 @ Orielly's.  There are links on the forum for the part you need.

That said you really just need to bite the bullet and get a meth tune, I know you don't want to, but peace of mind and realistically it is the only next step.  Doing any other installs would be a waste of $.  Your meth kit is working, you are down to 112* that is huge from where you started.  Congrats btw, seriously, your setup is working well.  Only way to get better is tune for the added octane and cooling. I view it sort of like adding high perf air filter and colder plugs without doing tune.  you just won't see much benefit without the tune.  Talk to Brad, he will get you dialed in.

If I were in your shoes I would get a tune made for your racedays.  Have it setup so you start to spray much earlier.  IE when you are brake boosting @ 3psi.  Load the tune before you head to the track, and play around a bit on the way, pretty easy to get over 3psi boost on street, let the tune and OAR settle in on the drive, then HAVE FUN!

I would not have it spray while break boosting... you stall out your engine... 5psi start MAYBE...

good point.

 

[StealBlueSHO]

When the meth starts spraying your ECU takes a split second to compensate which will cause you run rich for moment... so starting spray I believe is a balancing act.. you want enough air moving through the engine to carry the extra fuel via meth without bogging out... I start my spray around 6 psi and it's progressive... a small amount at first but sprays more as the boost increases...

Works well for me... if I park my car.. start it 30 minutes later my IATs are 170ish... a quick sprint in second gear with meth instantly drops it 40+ degrees without pushing it...

either move your nozzle to a spot after the noisemaker or plug it. You will see a difference I believe...

During a full 3 gear pull I will often times drop below ambient temps...

It's not possible for temps to drop under ambient unless your juice is colder than ambient.

Sure... ever dipped your finger in alcohol? And then blown on it? Let me find a log for you...

Ahh i forget your running 100% meth

 

[polskifacet]

And humidity must be low where your at. cycling my memory through airconditioning and wetbulb temperature. Still not consistent, I'm getting a max cooling of 10 over ambient and i have 70% water which allows me to cool much more volume of air but since alcohol evaporates quicker you can get colder than me. you still must be spraying a boatload or meth lol.

 

[polskifacet]

Topher sho should try pure meth or denatured alcohol. might get him those low temps hes after.

 

[StealBlueSHO]

Enough to cool, prevent knock, and never worry about fuel pressure... a metric crap load.

as additional fuel, my windshield washer fluid is enough and in still only spraying 7 gph to your 15 nozzle so half.

 

[TopherSho]

OK, guys... Thank you everyone.    It is clear my performance is being limited a bit more than others and just bums me out.  it what it is.

I was wanted to avoid a meth tune but I am not going to be satisfied until I get my @#$&ing 12's.

Sooo... Brad.  I will throw some money at you later next week.  I have a trip out of town so no work this weekend. 

Since I have the meth kit we will do a meth tune.  It is NOT a progressive spray though... I hate to waste the kit so we will tune for it.    I will get you a sample of logs so you can see in advance where the spray is kicking on.  I think it's Bout 6-7 pounds based on observation.

Maybe later well do a e30 update after that ..

Jebus.. slippery slope meet beecker... /Plunge/

 

[polskifacet]

its very safe imo . knock sensors can pull out 10 degrees.

the 140f flash-point concerns me.  I do not think i can run pure meth...

Fair... But since I don't have 8 years of experience deploying meth on these motors, I trust that those who do have worked out a good solution.

I trusted them for a while and then they horribly failed resulting in the longest troubleshooting thread on this forum but I digress. Its not rocket science, there is nothing to develop minus controller logic which you know how I feel about that already. We all have the same goal with different approaches which is great! All of my approaches are daily driver focused. I'll get some dyno results too. Just saying darn washer fluid is performing better than expected. AJP is adjusting shift pressures because of the power I'm making. Plus is tremendously satisfying when something you fab up yourself works great .

I 100% agree with everything you just said. Glad to see your continued success!
