I finally took my 1993 Mazda RX-7 out. Over winter I gutted the entire engine bay etc. I installed a GT35R single turbo. The car is insane. Listen as I Boost to 10.5PSI.
It does NOT have a Blow Off Valve installed :-p
400 Horsepower RX-7 in Tokyo
Met up with a guy who has a 400 hp RX-7 when it's running at low Boost. To ensure the longevity of the engine he's running his T04 turbo at about 12psin (very low Boost). It has 2 apex seals on a bridge port motor. He gave a demo on the freeway and showed what it can do.
15PSI on my GT35R single turbo RX-7
Watch as I beat on my RX-7. Ever wonder what no BOV sounds like? Ever wonder if you can hear water injection? Have all of your questions answered in this video
7500rpm on my single turbo RX-7
Flame away. I totally misshift my first pull. The second pull I hit the overly rich area in my map. I can't give it full throttle. lol. Then the good pulls. Enjoy
26 PSI RX-7 GT35R Single Turbo
Ever wonder what happens if you hit fuel cut at 26 PSI on a turbo RX-7? Watch me do it on accident while tuning.
For those wondering, I had the ECU set to 20 PSI expectation and wastegate to 26 PSI. ECU will go 3.5 PSI over its limits before it cuts the fuel. Small logical error can make a huge difference.
I got lucky. I attribute a large part of that to the pre turbo water injection keeping my knock low and combustion temps low while tuning.
