These times were obtained from slipping the clutch from 3k on Falken Ziex 205/50/15 tires at 26 psi. Full interior with an extra axle in the trunk. Also, the tranny is going out.
i think you need to practice your launches. with all that torque you should fly out of the hole. try to launch high, spin a little bit off the line, take your foot off the gas for a second so the tires catch, and floor it again. i find that works much better than to have the motor bog down. and i let my foot off the gas for the tires to catch or else i’ll sit there and spin, when that happens i’m usually like a whole second slower crossing the line.
it takes tons of practice. i’m not expert, i’ve only been to the track like 5 times for a total of maybe 20 runs but thats just my 2 cents.
i’m actually about to post my numbers from lastnight so check it out in the forum.
Yeah… you should def be running a little faster than that with that motor and those mods. My stock 91 DA rs ran a 15.4 @88Mph on a 2.232 60’ with bald tires and slipping clutch. I was at full weight too.
Keep practicing and you will see better times. and yes, you are launching too low. I usually launch at about 4.5K rpms and slip the clutch. I get minimal wheel spin and come off the line hard.
slip the clutch@ 4k on the b20 keep the gas steady until ur almost all the way off the clutch then slam 2nd gear i did this with my old b20 in my eg and was pulling 2.1 60’s on street tires. gotta love them torqy b20s
4k seems to be the best imo for a ls or b20 i used to launch at 3k and the revs would fall too low and then back up just killing my 60’s with a 4k launch and slipping the clutch correctly ull pull 2.1 60’s wit ease =)
just wondering… for your b20 did you notch your Xmember for the ITR header??? i ask becuz i found that some ppl didnt have to… and i need clearification.
not bad though… what is the elevation where you are at? that can play a factor too…
i only took a hammer to the crossmember twice and i dont think it did much. After I put the header on and checked the cross member there was a good amount of space.
If i were you, i’d just take a hammer to eat twice and check. You’d be surprised.
