Hey guys, I'm going to race a buddy of mine on a back road (the 1/4 is marked on this road) next weekend. I need some shifting suggestions. When I shift from 1st to 2nd at about 6200-6500 RPMs it wants to get sideways and fishtail a little. Should I lower my shifting RPMs (ie, 5000 RPMs) such that I don't get any spinning? Or should I shift at redline but only give it enough gas (ie, 3/4 of the throttle) to avoid spinning then give it 100% of the throttle when I sense it wont spin?

What is generally the quickest way? :hmm:

Thanks! :highfive:

Depends how close of a race you expect it to be. If you will be in front of him, bang the gear and let him see the V go sideways:thumbsup:

If you think it will be close, you may want to drop your tire pressures down so you will hook up better.

I see you are in SC, I will be in Charleston for Thanksgiving week. You anywhere close to that?

He will be in a SRT-10 truck...it's bone stock but the guy knows how to drive everywell. He has had many performance cars. I dropped the PSI to about 25 in all 4. I'm running the F1s so I guess the question still stands. Help me guys...I don't wanna lose. :cool2:

I'm about 2 hrs from Chuck town. I go all the time.

So should I back off the throttle or back off the RPMS? :worship:

Keep it floored and shift as quicky as possible just before rev limit. 6500 RPm if stock. My V gets sideway's all the time but never enough to spin out of control. Stabilitrak will kick in anyway.
Good luck!

1. Air your front tires back up. You want to decrease rolling resistance ... airing down the fronts won't help you a bit!!!

2. Don't powershift from 1st to 2nd. Keep the go pedal floored but let the clutch out a little slower. This will get you a good jump without the instant hit to break the back tires loose. You'll have to start the shift a bit sooner to stay off the limiter.

3. Spinning your tires does not mean you're going fast, in fact it hurts your ET.

4. Practice, practice, practice ... most races are won or lost in the first 60' !!! Getting off the line fast is the key!!!

If you do it Hylanders way, Just powershift as quickly as possible and leave on traction control, this will limit your wheel spin, and will probably do it better than you can manually!
Infact, I think I'll try this out tomorrow.

Isn't that way bad for the clutch?

if u leave traction control on then you cant be in performance mode.....and supposedly nonperformance mode doesnt deliver full 400hp 395tq can someone verify

I was wondering if anybody was going to mention that. Potentially "getting sideways" during a drag race on a public road is not a smart thing to do, especially since it sounds like the guy doing the driving doesn't have much experience with his car. Be smart, take it to the track.

If that srt-10 hooks up and goes I wouldn't worry about gettin sideways b/c you will be behind him. No offense but that a big motor he's pushin.

Hopefully, he forgets he's driving a pickup and to weight down the rear of the bed. Otherwise, he's gonna be spinning tires. My dad's 55 Chevy pickup showcar/streetrod had a 400 SB Chevy and a four speed. We had to add two 3" diameter x 4' pipes filled with LEAD to get the rear end to hook up.

I have to agree with Katshot on the street racing thing in a $55,000 car. If you get sideways and run off the road, just hope there are no trees close by. they don't move out of the way very quickly.

Guys the road we will be on has NO traffic and for good measure we have walkie talkies with someone at both ends to make sure nobody is coming. :D If it gets sideways then this means at about 45 MPH it the backend will start sliding sideways about 1 ft but it's well under control. No worries but thanks! ;)
The SRT 10 weights 1200 more than our cars. His weight distribution is way off and he is bone stock and mine isnít so weight to horsepower is heavily in my favor. All the car mags put the V as being faster. Anyways, thanks. :worship:
Now back to the question.
Just thought holding the clutch in while at WOT would burn the clutch so I was thinking either donít shift into 2nd at redline but instead shift at something less so that I donít get any spinÖ..or shift at redline but just donít go WOT till you know it will hook up (say Ĺ WOT for a second then WOT).
Thanks for all the help guys! :worship:

Hey, I haven't got anything against street racing. Just show what the V Series is all about. My first street race was with a TN Highway Patrol back in April. I won the battle but Motorola won the war.

Guys the post is about launching not where to race.

Wow,

Things can get sidetracked, huh?

Anyway, if you're concerned with loss of traction and acc on the 1-2 shift, then just lower your shift point to 6K, this will reduce the engines power upon re-engagement.

DO NOT rely on the electronics as they can be very intrusive and cause major engine bog.

Slip your clutch slightly on the launch, then shift into 2nd at the lower rpm, then continue on as you normally drive, this should net you a good e.t., in your case a win.

I agree w/ ctsv05. Ride that clutch out a little to guarantee no spinning on takeoff and then lay in the throttle.

Yeah, that V10 IS big but a CTS-V should have no problem with it. The only test I found showed the following:

0-60 = 5.02sec.
1/4 mile = 13.62sec @ 102.8mph
Top speed = 154.58mph

No slouch for sure but I think if it's a stock vs. stock race, the 'V' should win.
And BTW, I have a PDF file (I can email to anyone) of a nice article from GMHTP magazine that details the best way to launch a GTO. My guess is the technique should be the same as with the 'V'.

Just don't "powershift" first to 2nd and shift as high as you can. I just can't imagine the spinning at ~45mph to be too egregious.

Further, that SRT-10 is like moving a brick wall through the air. The higher the speed, the greater his disadvantage. Even if he gets the hole-shot, I can't imagine him holding on to it.

Normally, I would agree but considering the SRT-10 holds the record as the fastest production pick-up in the world with a top speed of over 154mph, I'd say hoping for the acceleration to be greatly inhibited by aerodynamics might be a little presumptuous.

Thanks guys!....again it's simple math....wieght to HP his = 10.2, mine is 9.1 (3850 lbs and 420 HP) that is about 11%. The launch will be critical...he can not launch his above 2000RPM because of the SRT-10s MAJOR traction problems. Again I think it will come down to the driver.

Do you have an application that associates with a .PDF file like Adobe Reader? You'll need that to open a .PDF file.

I understand, but let's be honest---that's still a lot of beef to be moving through the air... :)

Yes it's bad for the clutch ... so is power shifting. Racing is hard on numerous components. Do you want to be fast or do you want to baby your car? There's a great saying about drag racing: Drive it like you stole it!

I have almost 20 years of drag racing experience in everything from an 8 second Camaro to a 12 second Lightning. Run the car like I said and you'll get the best ETs from it.

Oh yeah, one last word of advice sure to drop at least 2 tenths off your 1/4 mile time ... paint your car PLATINUM SILVER!!! It's by far the fastest color!!! LOL!!!

I'm with Hylander, "Drive her like you stole her" It is harsh but true when it comes to drag racing.
Bring your F1 tire pressure (rear only) down to 18 to 20 psi cold. When you are going to race him before you line up do a very small burn on the tires to get them a little sticky. Line up, and ride the clutch out from 3500 to a full throttle. power shift your gears at full throttle 2 hundred rpms from your redline. And by the time you hit third you will have the race as you can look in your rear view and see him in back of you..
Have fun, and let us know how it turns out...;)

You're right but 500+ foot/pounds of torque goes a long way.

If the SRT10 is a crew cab 4 door you will beat it rather easily as long as you don't spin your wheels. If it is the smaller, lighter regular cab you will need to really be on your game to win. You still have the faster vehicle but he has a more consistent vehicle and you say he is a pro driver.

Joey'sVee
11-08-05, 04:52 PM
He has the smaller one....only 5100 lbs. If I get a good to great launch I will win...if not I will lose braging rights. Looks like we won't race till after my headers hi flow cats and StealthV tune now. If thats the case I should get him with just an average launch. I should be packing about 450 HP at the crank then (compared to his bone stock 500 HP) and 1200 lbs lighter.

I think it's a drivers race.

We are also going to try to race from a roll say 3000 RPMs each. Do you guys think my chances increase or decrease from a roll like that?

Thanks for all the help!

It doesn't matter - they don't hook up on stock tires. They have 22" rims which means they have very little rubber between the rim and the pavement. I've seen lots of them run (there were 4 at the track last time out) and I'm always underwhelmed. Last time out (just 2 weeks ago) none of the 4 broke into the 13s. They were running very low-14s at 104-106 MPH. I didn't notice whether they were big ones or little ones. The MPH would net them a mid-13 timeslip if they could hook up, but they can't.

If you get any traction whatsoever you should be able to pull away decently.

Sounds like the V. Our mph would get us 12 second runs, but we have no traction.
As for the weight and power, you may be surpised. I ran with a C5 vette and pulled a little off the line, I guess from the extra torque. Then we were 1 car apart up to 140, then I started pulling away. I thought the Vette being the more aerodynamic and lighter car would have pulled on me at those speeds.
I think you will beat that truck every time, if you don't miss gears!

If you have an 05 V the superior high rpm breathing of the LS6 motor will win out over the LS1

You specified an 05....would an 04 V be the same way.
