How much was the turbo blanket?

 

$100

 

So you just slit a hole in it? It doesnt want to continue seperating or fraying?

 

I measured where the wastegate arm was then cut a slit in it with a razorblade and dikes (to cut the steel mesh). The fabric is coated so it should not fray. The fiberglass insulation could start fraying some so next time I have it off I'll probably try to stitch up the area on both sides of the slit with some safety wire. Real safety wire is very ductile so it can be bent around quite a bit before it breaks.

If you are interested I'll post some before and after pictures. It will give me something to do tonight since I forgot to get the dang fuel line fitting release tool when I was at NAPA today. My injector swap was suddenly halted...

EDIT: Well that did not take long, all of 30 minutes from start to finish. Here are some before-after pictures of the slit. You can see a before picture of the blanket still installed earlier in the thread. The first picture shows the blanket removed from the turbo (duh) before stitching. The second shows after the stitching is complete. The third shows it reinstalled on the turbo. Much better! Basically I just looped the wire around it like I was sewing it up. The cut end of a piece of safety wire is very sharp so there is no need for a needle. I've jabbed myself with it before (and drew blood) while wiring up my bike.

 

Very cool. How did you sow with the safety wire if you dont mind my asking.

 

Still awake watching the F1 Australian Grand Prix. Raikkonen has cajones grandes.

I looped it around the cut edge over and over, pulling it tight after each loop. Think of a spiral bound notebook; Take a look at this zoomed in image and see if that makes sense.

 

Very, very nice job, turbo install and mod to blanket. You certainly DO take pride in what you do.

I have been considering using a thermal blanket as well. I currently have a stainless heat shield. Where did you get that blanket from? I think I just might take that route.

 

Thanks. Turbo blanket is from Alamo Autosports (see above). They are sold by several places, including some ebay vendors.
OK since I just did the injector swap I am including a picture of the RX7 Turbo 550cc injector next to the stock '99 injector for reference. It is a lot larger in diameter as one can see. However it drops right into the engine; the rail, manifold, and connector all fit like it is stock. Whoever first figured out this is a plug-and-play solution for the Miata, thanks



Duty cycles are much lower now, less than 50% which is what one would expect with the injector being about twice as large. I changed req_fuel after the install, but even so had to tweak the idle and do some log runs to get it worked out. I also ended up enabling accel enrichment and tuning that as well. The car drives very well and I am quite pleased.

The turbo inlet is loud with my CAI setup; it sounds like a big vacuum cleaner. And when I close the throttle the compressor surge is even louder plus it makes this goofy raspberry/farting sound. I think I need a BOV
