Thank you. There is a lot of help available for turbo Miatas.
I wonder how turboed Yamaha R1 would be supported?

The radiator is Summit drag race radiator GRI-1-25182-X.

I still have issues of keeping all bolts tight between sessions, safety wiring wastegate bolts between every session get old quickly.

I'm very impressed with your dyno results. Can you tell me the part # of your turbo or the A/R? Garrett makes a number of versions of the GT2560 and I want what you've got.
Great going!

What settings did you have on your cams while NA and after you went turbo? Ignition settings?

I'm guessing the exhintake cam is helping to give those nice dyno results.

 

I have exhaust cam set according to instructions on exhintake thread in Miata.net forum. I played around with intake cam timing since it is easier to adjust, no need to reset timing. There appeared to be slight change in powerband by changing the intake timing, but I have not recorded it in degrees relative to crankshaft. It is fairly close to instructions on Miata.net and the testing was done non-aspirated.

The ignition is retarded from stock to having 6 degrees advance and EMU programmed to add timing on non boosted ares by 10 degrees. No EMU interference programmed in boosted area.
