letitsnow Posted October 26, 2011 Share Posted October 26, 2011 I know not everyone drag races, but I don't see many 1/4 mile times for L28ET powered cars, lets get a list going. Try to give as much detail as possible. I'll start. 60' 1.969 1/8 8.622 mph 81.57 1/4 13.458 mph 101.18 Details: Car weighs 2750 with fluids and me in it. Stock turbo, 8psi falling to 7 by redline, EVO 8 IC, MS2 v3, big injectors, msa downpipe, 3" mandrel bent exhaust with turbo muffler, N/A 'A' cam, 93 octane.

24OZ Posted November 5, 2011 Share Posted November 5, 2011 I think thats very impressive for a stock turbo. What rpm were you shifting at and did you shift to 4th? Would be helpful also to learn what diff ratio your using (lsd?) and are you running the stock tranny? Quote Link to comment Share on other sites More sharing options...
letitsnow Posted November 5, 2011 Author Share Posted November 5, 2011 I shifted around 5700, yes I used 4th. I'm using a stock open r180, from an automatic 280z, I think it's 3.54:1 and the tranny is a ZX 5 speed. I'm convinced that with a little effort I can go mid 12's, I've got it at 12psi now and it's a whole lot quicker. That was the only run I got that day, with a little practice I could probably knock a tenth or 2 off without upping the boost. I'm planning on buying another set or wheels so I can put my DR's on this car and hooking up the 2 step so I can launch with some boost.

24OZ Posted November 5, 2011 Share Posted November 5, 2011 Sounds like you have a great technique and are shifting at the right time, really surprised at how quick your 60' times are with a 3.54, what rpm are you leaving the lights at? Let's us know how you get on with the extra boost. Quote Link to comment Share on other sites More sharing options...
letitsnow Posted November 5, 2011 Author Share Posted November 5, 2011 I held it up around 3500, then slipped the clutch out while standing on the gas, I slipped it just enough to keep the car from bogging, boost came on right about when I had the clutch fully engaged. Hopefully with the 2 step and DR's I can launch on boost and do something closer to a 1.8 or 1.7 60'. Quote Link to comment Share on other sites More sharing options...
