Sweet. And it's fat in the VD'd I posted up top. Probably find more power when I fix that, found 30whp several PSI ago going from low 11's to high 11's.

looks like it dips quite a bit past 7, lean it back out, you'll gain more IDC and pick up power.

that power should be good for 130mph trap speeds, and put a hurting on most street cars that are not tx2k cars
Thanks. Yeah it rips to redline now. I moved it from 8,500 to 8,800 cause I kept hitting the limiter on pulls (which messes up VD) and I still hit it twice today.... I need to hook up a shift light.

Will pull some fuel and add some boost tomorrow.

On this part, just to elaborate, my goal is to get the power as high as possible while keeping the torque down for transmission reliability. Hoping to make 500whp and be able to shift at 8,500, fall to 6,000-6,500 and only have 350tq or so there. Basically the fastest it can be with a 6 speed and reliable.

But yes if you stand on the pedal in high gears it spools and makes torque down low too. I posted a 5th gear dyno here but it's not a full to 8K one.

Another thing a dyno is good for pat! Nailing that fuel curve. Repetitive pulls over and over again to get the entire rev range, and you have a lot by 8800.

Sure. I can do that without a dyno though.

I do need to get fuel tuned though, it's off now even in moderate load areas.

Installing 4 bar map now.

run mbc on the 1st turbo set at moderate level and get ebc for the 2nd and just taper up the boost

Pretty much. Going to put a MBC on the little turbo next (it's a 2871, I checked) and then turn it up some since I think keeping them at equal boost is best. But eventually will do ebc on big turbo for torque line if I can't do it without ebc.

These are with a misfire. I think I need to gap down the plugs. Still, running strong! And fuel needs work too...

Out of fuel at this point, pretty sure it probably needs more timing or better tuning/could make more power. 37 PSI boost. I think I can find a bit more power by lowering the front turbo's boost and upping the rear turbos boost as they aren't balanced right now. Still, for a budget turbo setup this thing is stupid fast!

5th gear, had to stop RPMs after this, it fell on its face.


3rd gear, no misfire or not much/not noticeable.


Still, 492whp VD in 3rd is bananas! No doubt it's over 500whp on a 5th gear pull.

I'm pretty sure you are our current master of absolutely insane crazy build. I mean that in the best possible way.

I just went from 89whp to 170whp and my car feels amazing ....how the **** you manage to keep that car straight and on the road with street tires is beyond my comprehension.

Well ******* done mate

I sitting here wondering how explosive the feel of that power coming on must be. I'm seeing a 200+ increase in both whp AND wtq over just a 1000 rpm range . . . in a MIATA!

Is that about like riding my brother's highly modified banshee when it comes on the pipe?

Thank you sir! I have Mickey Thompson drag radials on the car that I use for daily driving. They are super sticky and hook great.

It's not as explosive as the SC was as far as transient response, but yes it does go hard when it spools.

Thanks! It's 9:1 compression FM pistons, about 17 degrees of advance at 36 PSI.

Where are you getting the pressure source for the small turbo wastegate?
