You ever order something, and pay extra shipping cost so it will show up before the weekend... then you notice there has been no status update on the order... Called these fuckers up, and they are waiting for it to come in from the factory! If you offer rapid shipping on parts that you do not keep in stock you drop ship the part directly from the manufacturer to the customer. You don't wait for slow crate once a week delivery to your shop, put it on the shelf, wait a couple days, take it off the shelf and box it up, then ship it out the next day as a 2nd day UPS delivery!!! So, I don't have a MBC this weekend. Anyone know of a speed shop within 2 hours driving distance of Terre Haute, IN that carries high quality MBC's? Keith I also have a neat little basic EBC. Runs a mac valve, on/off toggle switch, and a knob. Makes for a two-stage. Off = wastegate, On = whatever you have the knob turned to. |

TRU in Indy might have some, depending on your definition of high quality. They probably have an XSPower or two in stock. I'm sure i have a controller or two laying around if you need a backup plan. They'll be homebrew grainger/ball-spring deals, but they work.

They have a cheap knock off in stock, and can get me a Hallman later. I will go pick it up Saturday. I will try out the cheap one and if it serves my needs I will just keep it. Keith |
Any idea what time you'll be in town on Saturday? I live maybe 8 minutes from TRU.

Turbosmart in-cabin knockoff. That thing isn't going to work worth a shit.
PM me your phone number, i'll see what i can dig up tonite. |
UP NEXT!
I am going through my whole collection of springs for the external wastegate. I will do data logs for each spring, show spool up and peak boost vs what the spring is supposed to provide, along with a virtual dyno run at that boost pressure. I will be trying out the SAE correction since is if 92 fucking degrees here right now! Keith |

Allllrighty then!
With the 4.4 psi spring installed I get the following spool up data: 2000 1.6 psi 2500 2.6 psi 3000 4.2 psi 3500 5.0 psi 4000 5.2 psi 4500 6.1 psi 5000 6.4 psi 5500 6.4 psi 6000 6.5 psi 6500 6.2 psi 7000 7.2 psi And here is the virtual dyno using 29.99 pressure and 92 deg F. https://www.miataturbo.net/attachmen...1&d=1409959528 Keith |

Now some results for my 5.8 psi spring. Hitting around 9 psi with this one:
2000 1.6 psi 2500 2.8 psi 3000 4.5 psi 3500 7.0 psi 4000 7.7 psi 4500 8.5 psi 5000 8.8 psi 5500 8.7 psi 6000 8.8 psi 6500 8.0 psi 7000 9.0 psi And here is the virtual dyno from this spring. Temperature was down to 85F https://www.miataturbo.net/attachmen...1&d=1409967474 Keith |
your setup creeps. period.
not the worst thing in the world, but yeah.... |

Ben is going to give me a spare manual boost controller he has in the AM, so this is my final update before gaining some real control of my boost pressure... swapping springs to make a change sucks ass.
Here is the spool up data from running the 7.3 psi spring. 2000 1.5 psi 2500 2.8 psi 3000 5.1 psi 3500 7.8 psi 4000 9.0 psi 4500 9.4 psi 5000 10.3 psi 5500 10.6 psi 6000 10.6 psi 6500 9.8 psi 7000 10.8 psi And the virtual dyno run at this boost pressure. Conditions were 71F 98% humidity, and 30.05"hg. https://www.miataturbo.net/attachmen...1&d=1409979286 I am pretty sure that my first virtual dyno run was done with the windows down, and I don't have the weather data from that run to make it SAE like the rest of them. Later, Keith PS: I was estimating 2650 for car weight with me in it, but tonight I went to the local truck scales and with a full tank of fuel, me, all normal junk like spare and jack car weighed in at 2660. |

I put a cheap (free to me, thanks Ben!) MBC on the car and aimed for 12 psi. God do I hate boost creep! Without boost creep I would be hitting 11.5 to 12 psi by 4000 RPM... as it is, I have to get the wastegate to start opening early, and I am only hitting 10 psi by 4000 RPM, and then creeping from there up to my peak boost.
Here is the spool data: 2000 1.5 psi 2500 3.1 psi 3000 5.1 psi 3500 8.6 psi 4000 10.3 psi 4500 11.2 psi 5000 11.9 psi 5500 12.2 psi 6000 12.1 psi 6500 11.0 psi 7000 12.5 psi And here is the virtual dyno graph of the data log. https://www.miataturbo.net/attachmen...1&d=1410103588 Next step is just a hair more fine tuning now that I am hitting my desired boost pressure, and next week a trip to a REAL dyno as well as a trip to the closest 1/4 mile track. Later, Keith |
A question for the knowledgeable in the group:
Would my boost creep be mitigated / eliminated by switching to a dump pipe on the external WG rather than the poorly located return to the BEGi downpipe? Keith |
that usually does help
going to be crazy loud tho |

Corky was too busy coming up with new non sequiturs.

Do NOT make friends with Stephanie! Here friends seem to die a lot.
A couple weeks ago when I couldn't get an answer out of her, it was because she had to attend a funeral, this last time I e-mailed her three days in a row with the same questions, a friend of hers had a stoke and died. These may be real deaths, so I don't want to make too much fun... but hire someone to fill in if you are going to be gone so much! Personal tragedy is no excuse for corporate production or customer service failure. My intake build sheet is on the work bench... when it is done on Friday it and the dummy MAF pipe will be sent out for powder coating. The same guy doing the intake has a picture of my engine bay so he can make a heat shield... So, apparently they do not have a standardized heat shield for the S6 setup on an NB1. WTF? I actually asked Stephanie once if this was the first 99 with the S6 kit they had ever done when asking why there were no instructions, and I was told no. I think that was a bald faced lie. Parts don't fit right, there are no instructions, it has boost creep, overall it is a bad design... I think I am the beta tester for this fucking kit. Keith |
Do you have it in you to take it all off and start over again?
Because this is ridiculous and i'd LOVE to see either Stephanie or Corky set foot in this thread. I'd love even more for you to send the whole kit back. |
Did you tell them that the reason the heat shield doesn't fit is because your non-standard brake lines are in the way, or did you blame it all on BEGI?

The wastegate dump back to the downpipe is in the way, not my brake line. If I take my wastegate off the damn heat shield fits fine and clears the brake line with about half an inch to spare. Keith |
