Cremaster Racing ...Google it. First off, the car! 1979 Datsun 280ZX ($700 on craigslist) It has been through 5 races so far in 2 seasons, with one 4th place finish (lucky). The car has been through a lot, it had all the typical Japanese steel rust issues and we have spent a lot of time getting it rigid enough to keep the seat from falling through the floor (again). We are in the process of swapping in a more modern RB20DET after we realized that we can't compete on the straights.

turbogrill posted a topic in Technical DiscussionsHi, I am thinking in swapping in a mild race cam into our 280zx. Most people who do this also increase the compression from 8.3:1 to almost 10:1. I want to stay with stock compression for $$$ and Points reasons. From what I understand a hot cam and stock compression results in poor torque at LOW RPM (and we don't care about that). At HIGH RPM there will be so much air in the cylinder so that the pressure is high any way? So the effect of hot cam and stock compression is mostly an issue for street cars? (Of course it would be "better" to have a higher static compression, but not really feasible for now).
Hi, The timing advance in our 280zx is static over 3000 RPM. The mechanical advance "bottoms" out over 3000 RPM. Would it be better if the timing advance continued to increase over 3000 RPM in relation to the RPM? So instead off: 1000 RPM: 25 deg 2000 RPM: 30 deg 3000 RPM: 34 deg 4000 RPM: 34 deg 5000 RPM: 34 deg 6000 RPM: 34 deg Having: 1000 RPM: 25 deg 2000 RPM: 30 deg 3000 RPM: 34 deg 4000 RPM: 38 deg 5000 RPM: 40 deg 6000 RPM: 42 deg Would this increase power at higher RPM? (The numbers above are not exact, but in a ball park)
turbogrill posted a topic in Technical DiscussionsHi, I have found this awesome wideband controller, but not sure if I need it. It could be useful to improve MPG. I noticed that some people here are very concerned about MPG and fuel tank size. We are currently running a little rich, but I have no clue how much rich. Does it make sense to buy one and make sure we are at a 12-13 AFR on WOT? From what I know we could be running 8 or something now. Thanks
