122.xx mph trap speeds,
BUT I'm only running 12.7's and 12.8's. These are my best times to date. I have only made ten passes total with the car. Does anyone else have a hard time getting into third at the track with a short shifter? I made 439rwhp during the summer and even though I'm running some Toyo street tires, I still think something isn't right. Any replies?????????????

you can't drive....

what are your 60 times??? I am making about 420 myself and although i have no problem getting into 3rd my 60's are 2.4-2.5 (which is aweful as we all know)range with traps around 118 and times in the upper 12's...my problem is simply traction even though i run a bf ta/kd 285/30 in the rear I dont really get much traction until 3rd....i plan on putting in the kaaz unit and using some drag slick to really get the times i should be hitting...

what rpm are your shifting out of second at? the more i wind out second via pass 8500 its becomes hard to get into third, but if i shift right at 8500 or before it goes in much easier (just something i noticed). the power is there for a good e.t, thats shown by your trap speed, just gotta get some traction and a decent 60'

My main problem is by focusing so much on getting the car into gear, I neglect to keep my right foot floored. I am going back to the track in a few- hopefully with better results. Thanks to all who responded. |

My best 60' so far was a 2.1 I believe. They are, however, mainly in the 2.3-2.5 range. I've been shifting at a different RPM each time. Last night I was shifting at 8000 in between each gear. Do you think thats too low? My main problem is by focusing so much on getting the car into gear, I neglect to keep my right foot floored.

You guys should be well into the 11's with over 400 rwhp. Get some drag tires! Not only will they significantly improve your times, the soft sidewall will absorb most of the shock instead of your diff.
When I first got my fd I would occasionally miss 3rd, be loose and try shifting it with the palm of your hand. |

I usually always shift rather slowly into 3rd compared to the other gears, there is a much higher chance I will miss 3rd when trying to shift fast, I've done it many times at the track, but practically never on the street. I think it is because on the street I always shift using my palm and I am more used to shifting that way, but at the track I hold the stock shifter on the side and I guess I am just not as accurate that way. It was the last night of the year, I'll get some slicks for next year. I shift between 7500-8000, not trying to over rev the old motor. |
*UPDATE*
I made three passes Saturday, two of which were improvements. I now have exactly 12 runs with the car. 1ST R/T .196 60' 2.304 330 5.686 1/8 8.264 MPH 98.03 1000 10.438 1/4 12.243 MPH 123.19 2ND R/T -.018 60' 2.62 330 6.17 1/8 9.002 MPH 93.61 1000 11.233 1/4 13.064 MPH 124.16 3RD R/T .025 60' 2.176 330 5.441 1/8 8.040 MPH 97.74 1000 10.217 1/4 12.031 MPH 124.74 Running the GR67 kit, 14 psi, street tires, stock lsd/diff, and stock suspension. Any advice and/or comments welcomed. |
you need stickier tires............but you will break driveline parts if you do.... 124mph is great!
|
12.0 is alot better, atleast your improving! keep at it, its all in that first 60'

also 122mph traps is indicative of of less power than u said u dynoed at. |

Awesome chris, trapping 124 mph at only 14 psi is quite impressive....looks like that Gotham turbo kit that steve specced out is putting down some serious power throughout the rpm range. I need to get out to the track with you sometime next season :)

Thanks for all the advice by the way. |
hold the rpms constant, no point in bouncing.

Should I floor it in first, after I hook? Thanks for all the advice by the way. Your single turbo probably doesn't spool up as fast as my stock turbos so that will hurt your launches unless you can keep those revs high and not let them drop below 4k. And if you do it just right I don't think your back tires will spin. |
