Will it do a 45 degree wheelie? :)

It doesn't have enough power to do that. But I was launching the piss out of what it has!

I'm really shocked at how soft your suspension is! even just from a small tap of the throttle, the car rocks back.

That's hookin' up! :party:

Finally got a couple in-car videos uploaded of my runs.
The AMG staged with the back wheels in the first run, I wasn't expecting them to run us like that so I wasn't ready and left super late. A bunch of people told me they recorded videos but I can't get anyone to send them to me or upload them. I don't feel like my car squats at all, certainly nothing like Pat's is doing. |
Nice run! It sucks when they let someone stage on the back tires, I've had that happen to me too... Funny to see you running down a AMG!
Your car is part of why the Whipple is coming off and the turbo going on. How much boost are you running? |
Noiceee!!
That car will do 10s with well set up lc/ffs |

Your car is part of why the Whipple is coming off and the turbo going on. How much boost are you running? For those runs it spooled to 14psi then gradually creeps up to 19psi (crappy wastegate design). https://www.miataturbo.net/attachmen...ine=1454552792 I swapped it back to a lighter spring now and trying to tune EBC so I can raise the boost when I really need it. I feel like I'm going to kill myself if I keep trying to drive it like that all the time on street tires. |

I keep thinking that one of these days I should take mine to a drag strip just to see what it's like. :) --Ian |
@pdexta - what's your rear spring rate? Based on your videos vs. Pat's - it looks like there's a big spring difference.

If it's creeping due to poor wastegate flow, then the spring isn't going to get you less boost at the top. What WG do you have?

fwiw- I've read that your WG port location is ideal. I've seen it on a lot of race cars- including AAR's Toyota prototype (long tube manifold.) But what I don't know is to what degree the angles of the port impact the performance. Or what putting the EWG so far of the port does. The AAR gates were on a short stub at ~45 angle iirc. Need to find the photo/story.
Wonder what a softer rear spring would do for your launch/60ft. |
I made a thread a while back about the creep and everyone seemed to agree that the 90 right off the turbine housing was the issue.
From watching Pat's video softer springs would definitely help, but I was happy with how it ran and don't have any plans to swap suspension out. They were already threatening to kick me out if I went 11.49 without pants, firejacket, and 5pt harness so if I do go again that's my only goal and I think that's possible without any changes. |
You need more power on the launch, not less spring. Car bogs hard on your launch. I'm on the bump stops anyway when I launch. Launch control around 15 PSI one pass would get you kicked off that track. :)
I think the gas velocity where your gate ties in is very high, and you have a sharp 90 there. Putting it at the manifold (slower velocity, easier for exhaust gasses to turn into the pipe for the gate) or maybe porting the turbine with a round edge going to the gate would help. Short of making a new spot for it. |

I've got a brain built diypnp that has 4 output wires; power, ground, o2, and ebc. I've read into adding launch control a few times but as soon as I take the case off the MS I start crying and frantically try to put it back together. |

The best passes I made were when the car bogged, if I launched harder it would spin and I'd have to peddle it and end up being slower. I think you're absolutely right about launch control though. I'm just too dumb to figure it out without some major hand holding.

I can't tell you how to wire it inside your computer, but I'll help you get the settings dialed in, I know how to do that. |

Yeah without launch control setup, you can't launch very hard without blowing the tires off.
