Thread: Need advice before a go to the track, PLS LET ME KNOW !!!!!

How are you guys doing ? I have a nissan sentra b-14 with an Avenir sr20det swap, EMS ecu, my question is what do i need and how much boost so that i can run 13.99 on tires, i just want to enter 13 sec. Please let me know, thanks !!!

Take off those huge wheels!

12lbs should get you well into the 13's pretty easily if you get a good launch/60ft.

But it also depends on your tune, track prep, driving ability etc..

Alot of variables.

Yes i bought new tire especially for the track 205/R14/80, and at what rpm do you have to launch because i don't want to have allot of tire spin

You not going to get a solid answer for what rpm's to launch everyone is going to say... "every setup is different you have to find out for your self". Since I'm not an A-hole I'm going to tell you that with your set up you want to launch at between 4000-6000 RPMs. Launching is mainly about clutch work first. Then focus on what rpm to launch at. The tires that you bought I hope that they are street slicks or full slicks because this will alow you to run much better times due to the tires better ability to grab the ground. I mean you can still use all season tires but your style of launch is going to change dramaticly and you can only get so far with them even if yor a good driver. Nice B14 by the way very clean swap.

Thanks man i will try it out and let you know

Update update

I just got the clutch master clutch 6 puck today, going to run with hopefully 12psi, the streetlegal is on 11 of july, realy looking forward, gonna let you know, any tips ???

pre-load at the line and don't drop the clutch off the line. Let is slip out smoothly that helps with traction off the line.

QFT!!!!

DO NOT JUST LET OFF THE CLUTCH HARD! Feather it.

If you have an adjustable suspension set your Rear at full stiff and set your Front at full soft. This reduces the weight from the front of the car transferring to the rear when launching, and that is something you dont want because it will kill your traction. Also minimizes wheel hop.


Make sure your rear tires have ALOT of air in them to lower the rolling resistance. (45- 50PSI depending on your tires)
