First time to the track, input apprectiated..

[typhoon-crazy]

first time at the track, 16psi- 13.7@101mph. with a shitty 2.3 60ft time.

this is with 20g 14cm turbo, tons of ic mods, nitrous express wet kit with 75 shot. i had very little detonation but i really need to work on tuning and learning how to race at the track. its a different animal from street racing. so let me have it what am i doing wrong? i was expecting some 12 second time slips.

by your 60' times your launch is way off, and seems maybe you have some spool up issues. I got a 1.9 60' with launching from idle, no boost at all.

how to race at the track is a whole nother beast for sure. this is what I have learned since owning my personal money pit :wink:

1. a good launch is paramount in these trucks, at first don't worry about reaction times, they will just mess you up. When you are starting out and tuning you need to be more worried about launching a specific way everytime, not reaction times. Each truck is different and likes to launch at a certain PSI. Find you sweet spot and start working from there.

2. trip the staging lights and then put it in neutral and rev the motor once or twice, to help build vaccum and hold the brakes harder. Then pull it back to drive, not overdrive, I believe this will give you a little better line pressure and make things engage that normally wouldn't in OD, a tranny guy can jump in and explain better I'm sure. I usually start to build boost as soon as the second light goes yellow, not to the floor but let it start to creep up slow, then when the lights start to click down I bascially floor it and have good boost for a launch (between 8-10 lbs for my truck).

3. You have to be very careful in these truck though, you will have to figure out the sweet spot of the launch for YOUR truck. Cause if you are launching with to much power then you are going to hurt you 60' due to wheel spin. But there have been some who have reported great 60' times with just launching at whatever they can hold with the brakes and just try to keep it straight in the lane. Seems a little excessive(but funner) to me, but each his own I guess.

4. as far as getting your tune on, that is a whole nother can of worms. naturally you shoot for zero knock at all times. keep the IAT's down, ice is very important for this. good luck figuring out the NOS spray, it will greatly cool things down but will also add extra fuel to the equation, which will slow spool up amoungst other things.

5. your MPH is pretty good and should net you a low 13 sec pass, but with a 20g you should be able to get it much lower, but that gets into the can of worms we were talking about, along the lines of chip burning, WBO2 tuning, blah, blah, blah.

basically you just have to play around with YOUR truck and see how it likes to be treated at the track, some go fast with a good beating, others need more finess to get there. sorry for rambling on if you knew this already, just seemed like you were new to syty's in general. good luck and keep us posted on the times.

ya i didnt get to launch on that run, the lights went up way to fast. with the nitrous i get imediate spool up. really trying to get some tuning going is my next step. but thanks for the input

F the lights, just go at your own pace when you're taking a run down the track. Don't worry about the guy next to you. Doens't matter if you get a reaction time of 2 seconds, just work on your launching technique and see what psi your truck launches most effectively at.

ya i wasnt giving a shit about the guy next to me. i just know my truck should be alot faster than a 13.7. i was just trying to figure out some tricks to the track. im figuring with a good launch i can drop at least .75 off my time

yea... forget about reaction and concentrate on gettin it right. one mistake that could get costly though, when you throw it in neutral and try to build some boost. make very sure you don't put it back in gear until the revs comed down. i know this sounds stupid, but when you're startin out strange things can happen that you would later say "did i really do that." aslo make sure you launch in d on od. easier on tran. sounds like you jsut need to do a little tuning and the numbers willfall quickly

 

[typhoon-crazy]

yea thanks for all the help guys. much appreciated! ill let you know when i get some more track times.

Drop the N2O for now, simplify and tune what you have. Nitrous doesn't usually work that well on SyTy without a good tuner.

Your running what is considered a good ET for a stock ty. Your 60' time sucks, it should be 1.7-1.8. That alone should drop you into teh really low 13's, if not a clos eot a 12.9. A well tune Ty with your mods can run 12 w/o Nitrous. It can even run a 12's with a stock turbo (look at the post below) Are you using a stock torque converter with the 20g 14cm2? (The 14cm2 exhaust housing really could use a higher torque converter than stock.)

I don't know if it was first time with this vehicle or first time in your life running at the track. Anyway if you already know what i'm about to say, sorry if not you learned something new, ok?

Like everybody says, don't worrie about the lights, the time don't start counting until you break that last light beam in your stageing. So you can sit there for 5 minutes before you take off. Just take your time and build some boost, but remember: Don't power brake to long, you put a lot of stress and heat on your transmission when you do that.

yea i run a stock tc with the 20g-14cm. my spoolup is acutally pretty good with my external gate, not as good as the stock turbo but pretty close. dont know if i said this yet but i got these times using 91 pump gas.
