  RB guys, tips for low 60ft times? (s13 rb25det)


going out to the track today in hopes of low 13's in the 1/4 mile. last time i was out there i was running 14.1@101 consistantly. this was on the stock PFC base map (which dyno'd a weak 180whp and 160tq). my 60ft's were also very a consistant 2.1. i have a competition stage 3 clutch and i cant figure out how to lower my 60fts. ive tried launching at different rpms, dumping the clutch, feathering it and i always get 2.1.

im using some 205/50/15 bfg drag rads that i got for free. i know they arent the best choice of tires and even look ugly on my car but its all i have right now.

im now tuned to 266whp/245tq at 12 psi and 286/260@14 psi. id like to get my 60's down to 1.8-1.9 with these tires but im not sure what the trick is. on my h22 civic i can get 2.0s at least all day with the 14" street tires feathering it. any advice would help.

well i managed to get pretty consistant 2.0's off the line and got a best of 13.24@106 with the 12psi tune (dont think i will be using hte 14psi, im scared to blow my turbo)

what are you guys launching at? i was launching at 4500. i didnt get enough runs in to try launching higher, still getting used to doing rwd launches. im feeling 12's if i can get under 2.0...

Well Since we have the same car with the same motor, Ill give you my tips,

First, Is to get some type of Posi or LSD, I personally run a Welded stock rear end, The RB seems to like the 408 rear gear.

2nd, I would get a Bigger tire, I run 275-50-15's BFG DR's and Im Having a problem Spinning to the 60ft still, But Im also running a 2 step, So you shouldn't have the same problem i am.

3rd, The Rb likes leaving between 5,000 and 5500RPM's.

I leave at 5500 off my launch control @ 10lbs of boost. The last time at the track I was only cutting 1.7 60's Spinning threw the 60' mark.

I have went 1.6 60ft with a MT Drag Slick and No launch control, leaving at 5500-6,000, But as a suggestion watch out launching as hard as I do, at a 6400RPM launch I snapped both axles, Also at a 3,600RPM launch on my launch control I Twisted the U-joints out again makes 2 sets. ( I have upgraded the Driveshaft to hold bigger U-joints now from ShaftMasters)

But so far on a set of Stock axles New, New Driveshaft, new launch control, DR's and 15" wheels, I have did almost 20 Passes with No breaking @5500RPM's.

Hope that helps.




Propane=6's on the way!!
