Can you post a recording of it?

About a template... I can attempt to measure and draw this up in CAD when I get mine. I'll post the file for everyone to download (if I can indeed draw it up). It would be a HUGE file, dimensionally, and pretty expensive to have plotted out at a retail place like Staples, but at least folks would have measurements.

Fedex stores will do 3ft wide plots at something like $0.50 per linear foot + ink.
I use them for my ski templates and it usually ends up being about $6 per print. My templates don't use much ink but I can't see it climbing much higher than $10 if you can keep it under 3ft wide.

As long as I simplify the amount of curves I don't see an issue, I went hog wild on the form fitting and made it really complicated, yet really really perfect.

Ignore the shitty plastic welding. It looks messy, but it is solid as a rock. I forgot to take pictures after I used my dremmel to sand down the edges properly. Plus, I heated the plastic just a touch to much hence my gloves leaving indentations in the plastic.

Honestly though? Who cares about the superficiality of the piece, or the "bling" factor of it. It is the most functional you can get with out creating custom mounts for the radiator, which I plan to do. So much unnecessary metal in the radiator/condenser piece that holds the vertical radiator bars to the radiator, I can easily envision a much more simple mounting system for the radiator and ac condenser which alleviates all the air cracks and shapes you have to work around. For those that don't want to spend the time to do it/don't care, I can see your point of view, but after making this piece it is a bitch to seal it 100%.

I'm pretty proud of this rear section and how it bolts & tensions the rear of the cowling to the bottom of the radiator/fans. This is the ONLY place that physically bolts to the car. The bolts tension the intercooler holes so tight I can't even physically move the piece.

See how I molded the plastic into the vertical radiator support bars? That was a bitch to get right, but it ensures no air flow around the radiator.

I could have done the plastic welding in a much cleaner fashion, but considering this was my "test piece" I did all the plastic welding and forming while it was mounted on the car.

Revlimiter's radiator will get the professional looking piece, since I have exact dimensions to utilize now.

Finally caught up on this entire build, have been reading it closely and taking notes like everyone else has. I don't think I've ever followed a build thread this closely, esp one that is 150+ pages! Love the meticulous attention to detail and that is an understatement. My gf's Tahoe just got rear ended so she's driving a Jetta. Curiousity got me under the hood and the plastic battery case reminded me of your work with the radiator shroud... except yours looks much more precise in fitment! loll Keep up the good work!

Glad you enjoyed it. I love it when I come across a good build thread that makes several hours disappear. The thing I hate the most is when you get to the end and there hasn't been an update for several years or they decide to stop building it!

OK, so Hornet, you requested some logs to help me figure out why my car is sputtering when I hit full boost, and killing my power, so here they are. I can't figure out what the issue is from the data but maybe those smarter than me can pinpoint it. Also posting my current tune in case it is a setting issue.

If anyone doesn't mind taking a look, I'd appreciate it.

I have to wait until next week for my -6an to 5/16 barbed hose fittings to show up before I can install my AFPR. I totally forgot to order some from Bryan at Fab9. :facepalm: Almost tried to use NPT fittings, luckily I didn't thread them and cause damage to the AFPR!

Current Tune

My brother and I were brainstorming things and I think we've got it pinpointed. What I'm looking at I believe is wastegate flutter/surge. Now that it is staring me in the face I think I know why this might have happened. When I was filing down the wastegate rod, I also enlarged the hole a little to get it down far enough to be able to fit the E-clip properly. What I forgot to do was increase the preload due to losing that little bit of tension.

I love lightbulb moments. Will be testing this tonight.:idea:

This video of an STI is EXACTLY what my car is doing.

I'm not sure what problem you're looking for (maybe I missed it) but that STI vid you've linked demonstrates what a 3port solenoid in interrupt mode will make an external gate do at full boost. it sounds like flutter, but doesn't affect power in any way, just makes the operation of the wastegate a lot more obvious.

Basically when I hit full boost I get the exact same sound as the STI in the video, and an interruption in power. It isn't a strong interruption in power, just a "wall" that keeps me from holding the boost limit. Only topping out at 270kpa, no spark blowout.

that ducting looks fantastic Jeff. What are your plans in regards to sealing it to the nose of the car?

I'm making a jig right now in the shape of the bumper opening so that I can get a good clean bend in the right shape. It really only needs to be the bottom and the sides that are fitted as the top is sealed with the radiator panel at the top.

Then I'll either plastic weld it or connect it with dzus fasteners so that it will be easy to remove.

Thanks for the compliment, I think it is pretty damn ugly myself, but its functional so I'm making myself be ok with it.

your logs don't show the boost fluctuating though.

also I hate it when people post logs of the weirdest crap and you have to dig through it to find the WOT pull. 2k rpm, start log, WOT, redline, stop log. DONE.
No offense :giggle:

(though yours aren't even that bad, I'm just ranting lol)

No I totally felt bad posting those long ass logs. I just don't like messing with it while I'm driving so I leave it running.

True, boost fluctuation is pretty tiny, but seriously what else could it be? plugs look fine, if even burning a little hot(white), my injector data is straight from ID's Megasquirt settings.

The only other thing I can consider is somehow my FPR is malfunctioning due to the 255. But then I'd see a really rich/lean spike in the area in full boost.

One thing, of which I don't know is related or not. But bring up the RPMdot/TPSdot plots, and you'll see a lot of spikes in the same area.

Also, should my fuel pump duty be at 100%?

hmm, I'll look them over again in the morning, but the dot spikes you mention sound a whole lot more like the problem vs boost fluctuation.

Installed the Fuelab 515 AFPR from Byran @ Fab9. Quite pretty for a FPR. After I tracked down the correct -6an connections I was able to cobble it together.

The return from my fuel rail goes to the inlet, and the outlet goes to the fuel return hardline. Vacuum is pulled from your OEM line. To dial in your pressure, start your engine, disconnect the vacuum line and plug it(engine will stall). Then adjust your static rail pressure to whatever you'd like(58 psi/4bar for me). Tighten down your locking nut and reconnect your vacuum like.

Then, change all your required settings on your fuel injectors to reflect them now outputting more flow(Flow,deadtime offset @ 13.2V, high & low deadtimes) and start autotuning your VEAL so you aren't running pig rich!

Still working on my VEAL map before I see if it helped my current issue. Don't want to run the risk of being to rich/lean in full boost.

The install was easy, more of a pain to find a spot to put it. I had to remove my oil separator and move it over to the left more, and then bend my clutch hardline a little but it is now out of the way. Looks like it is at a slight angle, but it is just the curve of the panels throwing you off...

The left -6an was replaced with a plug as it wasn't necessary.

all finished up. I need to use a little touch up paint here and there.

https://www.miataturbo.net/attachmen...ine=1413060092

This should be a fun project for this weekend too. I was going to powdercoat it but I think I'll just hit it with some caliper paint, which is pretty tough stuff.

https://www.miataturbo.net/attachmen...ine=1413060092

Finished up my Singular Hood Vents finally. Turned out really good. Didn't have time to pick up some black zinc hardware so the stainless looks a little out of place, but I can ignore it for now.

Carefully cover as much of your car as you can. Especially the engine bay. Tape up your seams! Or, if I had to do it again, remove your hood and do it outside. much easier cleanup.

Used a christmas tree bit to cut the holes. Cut them as close to the corners as you can. I had to do a lot of sanding which, being aluminum, ate through my barrel sanders like crazy.

https://www.miataturbo.net/attachmen...ine=1413434815

Angle grinder out the straight sections and cut the 2nd/3rd skin 3/4 of an inch farther back than the main hole. Sand until happy with your curve/it fits.

I used the really nice rubber included in the kits to prevent the paint from chipping.

https://www.miataturbo.net/attachmen...ine=1413434815

Self etching primer
filler primer
Wet sanded
Primer sealant
Semi-gloss black engine enamel

Really nice finish with the semi-gloss.

Final result. Quite happy with it.

dat heat extraction doe

Hopefully it is the last puzzle piece to good temps. I'm sick of tinkering for a while.

this car needs nothing but a solid tune now.

you're done son. don't let anyone tell you otherwise lol

enjoy it.
