Weather conditions 65* DA 1039

Not bad. Need a 60' closer to 2.00. Our cars run much better in cooler temps, 40-50*. DA is high.

All my best runs were with the DA on the minus side.

You may see good temps and DA at Fayetteville.

Blade, got to get those 60' times down, but then again you knew this already. Heat up those tires. Another choice would be to drop some of the unsprung weight from those 20" wheels you are using.

[DarkneSS]

Blade, doesnt make sense you are .6 tenths slower than someone with just intake + catback. Are you using those paddle shifter buttons?

[rtcat600man]

Blade..........few more things to make sure of.

1. Run 93 octane. Anything less and timing can be pulled from the engine. This as you know has been proven countless times by a few of our V6 experts.

2. Run you front tires at around 42 PSI or even a little more.

3. Run your rear tires at around 30 PSI. Need to experiment with this one.



good luck.

Yea.....The DA is horrendous at this track. 695 ft above sea level and you could feel the heat soak creep in around 1:30 PM.

Fayetteville is only 100 ft above, so crossing my fingers. I am also hoping to get a good idea next weekend because there will be a bigger sample of stock v6 and bolt on modified v6s.

I also had a full tank of gas on these runs.

Yea my cousin said the same thing, work on the 60' times and the rest of it will work out.

Nope using the sport mode tuned by Vince.

1. Would I need to retune for 93 octane?
2 & 3 My cousin suggested the same thing, my tires were at 34 PSI all around. I am also going to try power braking higher than 1500, maybe around 2000.

Ok here is another timeslip



Car #88 was another members car, who has the RS package as well thus the same wheels and tires. He ran a couple laps yesterday and last week, and he was getting 15.5 secs runs both weekends. The DA conditions were similar.

You guys can see in the slip that I am a .789 secs faster than him. On his next run we were side by side, but 1 car apart and same numbers popped up. So I am guessing that my car has had some serious improvements over a stock v6. But the conditions here at Zmax are kicking the Quarter mile times' ass.

[67 GTO]

I've found that heating up the tires real good makes a difference. I used to do a little burnout until I met up with HDRS who does a massive burnout before hitting the tree.

I was with HD when he nailed a 1.961 60' NA on the stock 20" Perelli's. I don't think he even let any air out of the tires.

He brake stands with t/c off and anywhere from 22-25k or just before the wheels break loose.

I've tried many different ways, t/c on and off, with DR's, 22psi, just off idle and up to 2k.

My best 60' (1.980) was with Goodyear summer street tires at 26psi, a good burnout, t/c on and just off idle.

Sometimes it comes down to the condition of the track.

Careful comparing the two. There's more to the car than just the engine mods. How much did Rod drop off his time just by slapping on the skinnys? In the two you're comparing one had great DA/weather compared to the other and these cars are affected a lot by weather.

So says the guy who saw 20mph headwinds and 87 degrees already Friday.
I'm not asking for a tailwind, just get rid of the headwinds, please.

Lapeer dragway by me is at 827 ft. but in November the temps. were low 40's and providing us with negative DA's

Retune for 93 octane? Ask Vince that one. I have no tune yet and just ran 93 Shell, so that I didn't have any timing pulled.

Scrming found that the higher RPM launch was worse than just leaving at 1000 rpm's.

I plan to create a sheet and document my conditions and set-ups at the track. Making 3 passes and then make some adjustments. Try different set-ups and see if I see any patterns.

When my car got tuned octane was brought up. The car with the tune or without it will make the adjustments but it makes the adjustments on the lower octane by pulling timing which causes a loss in power. So Vince actually recommends using premium to get everything you can from the car.

Good luck tracking your set-ups. I know you had great weather that day but your times were still amazing for the mods you had.

Thanks for the info. I plan to do some data logging for Vince while at the track. I see that the track opens April 2nd, and I plan to try and be there for some passes. Then send that off to Vince and hope to go back 2 weeks later to see what it does for my Camaro.

What was your trap on that 1.980 60'? Also, you said you were running Summer street tires - on what size wheels?

To be honest, I think the wheel size and weight is more of a factor on our cars than the v8s. I seem to notice the 18 and 19" wheel-guys getting better ETs and way better 60' times, which leads me to believe the less-torquy v6's are having a hard time spinning the 20" drums.

Compound the issue with the crappy Pirelli tires, which break loose too easily - I feel the wheel/tire combo is creating too thin of an RPM area for optimum launch. Too low and the car bogs; too high and the wheels spin (yes, I know this is true for ANY launch, but I'm saying the sweet is not a wide enough range - or even there with the 20"/Pirelli combo)

And if you compare our v6 camaros to other v6s, you don't see any 350z's trying to tear up the 1/4 mi on 20's...

I'm trying to find a pair of super sticky DR or Summer tires to go on my stock 18" LS wheels - I would prefer to buy a pair of lightweight 18" wheels, but I'm also limited by my budget. I still feel the 18"s will be lighter than my 20x10" barrels I have out back now.

A sub 2" 60' is key for good times in our car. Along with a trap over 100mph. Due to the limited parts avail and weight of our car, I feel there is more we can do about the 60' than about the trap speed at this time, so this is #1 area to improve on.

just my meager $0.02

[67 GTO]

Details are in the post below. The GoodYears are on some cheapie ASA 19" wheels.

The wheel/tire combo is almost 1" shorter than stock height and weigh about 8-10 lbs less per wheel than my 19" stock wheels/tires.

I've trapped at over 101 mph before but ET on that run was 13.95.

Thanks for the info What size width is the wheel? and same question for the tire..

Wheels are 8.5, the Goodyear Eagles 9.7.
