Pyro Posted May 26, 2010 Share Posted May 26, 2010 car is running 7psi an on street tires first run was 10.01 aT 72 mph next was 9.93 at 73 last was 9.77 at 73. i want to run 10 pounds next about were would i set the timing. im at 18 deg. locked right now if you are running stock 79 non-turbo compression ratio (8.3:1) then you can run more than 18 degrees of timing with stock boost. try 26 locked. use the vacuum advance as normal. for 10 psi, I would use around 22 degrees. but 18 degree is too low. 8 more degrees will make it run quite a bit faster. I would use 18 degrees on a 8.8:1cr engine with stock boost (81 to 83 non-turbo setup). you should also consider installing a MSA stage 1 turbo cam. It would work better with the higher compression and make the engine less likely to detonate. Quote Link to comment Share on other sites More sharing options...
Pyro Posted May 26, 2010 Share Posted May 26, 2010 here is a nice table to convert 1/8 mile to 1/4 mile times. http://www.empirenet.com/pkelley2/eight-to-quarter.htm I would expect 9.3 second 1/8 mile times with your current setup. Maybe more timing will get you there. Quote Link to comment Share on other sites More sharing options...

1979280zx Posted June 3, 2012 Author Share Posted June 3, 2012 (edited) Got a new time on the car 10.47 at 73mph at 5psi of boost. What should I run the timing at to run 15psi of boost.I have a n42 block with dished pistons an a p90 head now.I know my compression is lower now so just wanted to ask.

letitsnow Posted June 3, 2012 Share Posted June 3, 2012 Locked timing isn't that great, you need to run less at peak torque and more as you move up the rev range. I'd say right around 20 to start with. Just to give you an idea of what a proper timing curve can do for you, I have a mostly stock L28ET, 'A' cam, IC, full exhaust, bigger injectors, stock turbo, run by MS2e. With 17psi falling to 10psi by redline, I've run 8.4 in the 1/8 with a best trap of about 87mph, best 1/4 run of 13.0 and best trap of 108mph. That's ~100+hp more than what you've got going on. What is the fuel system like? ecu, injectors, ect? Quote Link to comment Share on other sites More sharing options...

letitsnow Posted September 1, 2012 Share Posted September 1, 2012 Wow! What's the car weigh? Maybe I have some left in mine, my best so far is 8.1 at 87. Can you actually hold 15psi to redline? Quote Link to comment Share on other sites More sharing options...
