400+ HP GT4088R Bridgeported Turbo-NA RX-7 Afternoon Drive
Just a silly little video I made with my RX-7 as an excuse to not cut the lawn. I just installed a new transmission and am trying to get used to the new kevlar clutch, which makes launching a little difficult. There are a few 1st and 2nd gear pulls in the video on low Boost. The roads shown were deserted for miles and I didn't exceed the speed limit. The car makes just over 400 RWHP at low Boost (13 PSI) and somewhere around 500 RWHP at high Boost (16 PSI). The engine is a S4 NA 6 port block with a small bridgeport. The turbo system is fully custom using a GT4088R, my own long runner stainless manifold, 3.75" downpipe, 3 x 24" Intercooler with custom tanks, my own custom upper intake, Microtech LT8s, 720CC/1600CC injectors, and probably some other stuff I'm forgetting. There is still a little tuning to do at low Boost so I guess I'll need to book some more Dyno time soon.





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.
