60 foot was good but i think with the 9" wide slick i can pull a 1.5XX I did 1.70 on my 22X8X15's set to 11 psi. So im pretty sure i can get it down there.

Don't think you'll break 1.70s without traction bars at the least. I'd love for you to prove me wrong, but I just don't think it'll happen in a street weight car.

The wider slick will definetly help.

That's the thing, they won't really. Contact patch is determined by axle weight and inflation pressure. Tire width has very little to do with it. A wider slick will just have a wider, but shorter contact patch with about the same net area. This is because tires are round and deform to the ground when they rest on it. More weight or less pressure = more deforming.

I was doing my burnout in 1st gear and not a very good one.

2nd gear will definitely help. Although it was awful warm that day, they could probably still use a little heat. I usually do a 2nd gear burnout in the water box, wait for white smoke to come out pretty good, then disengage the e-brake and let it pull me out. You know they're good on temp because you'll hear them make a ripping sound once you clean the water off.

But again the slicks i was using were 7 years old and had no life left on them.

Yeah, there are only so many heat cycles available to a tire.

Ive definetly go the power and with even more coming soon before i go back out i think some low low 10's are in order. haha my goal trap is 140+

Gonna need some serious traction and weight reduction for low 10s would be in order. There's a point where power will only increase your trap, not really lower ET.

Either way, great times and good luck to you. Get a cage though sir, that's a lot of speed if something goes wrong! :D

i dont get how a wider slick wouldnt give you more contact patch as long as they are at the same pressure, i do get that it dispurses the weight throught the rest of the tire which will cause them to no flatten to the ground as much but still, i think it would help some.

Yeah my car weighs in at 2080 lbs what more weight reduction do you want, haha. i want to get it to 2000 with a cage in it. But thats moolah....

Thanks, the intake manifold should net me quite a bit and with some new tuning and a bit more boost i should still stay in the efficiency range of the turbo right at 540-550whp range and then im maxed as far as fuel and turbo goes. But with that much power and colder weather i think low 10's are possible if i can get off the line and full throttle 1st 2nd and 3rd without just blowing the tires off.

I will be going back out probably beg of october whether i have the intake manifold or not by then so cooler weather and better slicks will still help quite a bit, Id be good on this setup with a 10.5 and with the trap i had in these conditions i think thats attainable. But again only one way to find out. haha

awesome times! Congrats Bro!

Like I said, the tire only deforms so much based on the amount of weight on it and the inflation pressure. If you get a wider tire, the contact patch gets wider, yes, but it also isn't as long, so it evens out. You'll gain a little more traction by increasing sidewall height for wrinkle though. This will store some of the energy you put into dumping the clutch in the tire and release it a little later, so you don't shock the tire into spinning.

A wider tire will get you more cornering power due to reduced slip angle, but this doesn't matter in drag racing.

This is why Top Fuel cars only have 17.5" wide tires, are pulling out 0.8 second 60' times, and are running 10 times the power you are. If wider tires made sense, they'd have them, since they're spinning the tires literally the whole track even with massive clutch slipping for the first half and only 1 gear.

Ah, word. Didn't know it was that light.

Traction bars like these:

http://www.sr20forum.com/suspension-chassis/179773-traction-bars.html

will help a lot.

i was looking into the traction bars but the thing is i was mostly told by several other people that traction bars are more to prevent wheel hop, On slicks you dont even have to worry about that. I know they keep the a-arms from moving around which i guess could in turn help keep the slick in place, i might have to try them out later down the road.

Ill see how a fresh new pair of slicks with a decent burnout do next time out when its about 30 degrees cooler out, haha

Nevermind....

Yeah. They certainly help with wheelhop, but they also help with slicks because they don't allow all the toe change you get with a hard launch in 1st gear at 6k+rpm. That's a whole lotta power (over 1000lb-ft of torque) when you do that.

BTW, you have a 2-step? Is it building boost?

no, no two step launch control. I launch it more how you would an n/a motor. I preload at 4k or so then when the tree falls throttle to the floor and rev limiter launch it. I could not imagine how much more it would rip the tires apart in 1st if i actually used a two step and built boost. Yes your not launching at as high of an rpm but your making more power so in turn it comes right back even.

Again ive done 1.70 on smaller 22X8X15 m/t's that were new and still not on a good burnout. Usually just like i was doing on these runs, Just heating them slightly in 1st more to clean them off. I have no doubt that im capable of at least a low 1.6 and possibly a 1.5 especially if i decide to get those traction bars. Im kinda up in the air about it right now.

I love how the car launches using the technique im using when i have slicks that will hold. With those smaller slicks on less power but using the same launch style i was able to pull those 1.70's but the slicks were still spinning a bit. I had them set to 11psi.

Im also thinking when i get these 24.5X9X13's that i might try a little bit lower tire pressure. 9-10psi or so. I was running them at 12 then lowered to 11. I think 9-10 should be a good sweet spot for that size slick. i tried 10 in those 22X8's and they were squated very low. But 11 psi looked like they were almost fully aired up on the 24.5's No tire squat really at all. haha Just need some more time to play around with things like that. Its the small things that make the biggest difference sometimes.

Steve Rockwood is giving drag race advice? I don't think that car has been driven in like 10 years dude, and even then you only went like twice. Armchair racer :)

If you disagree, bring it out!!

^Wow! Random post from a OG, but it was funny! LOCK IT UP!

lol havent seen that name around for a long long time, haha

Yes your not launching at as high of an rpm but your making more power so in turn it comes right back even.

True, but the higher rpm means you spin the slicks faster from the start. With a 2 step, you only make more power once the 2 step is off, making it so you don't blow them away right away. Not necessary though, do whatever feels right to you.

The bars will help 2nd gear as well. But yeah, 1.6 60's should happen with better slicks/burnout.

Remember to set them a little lower when you do a 2nd gear burnout. The extra heat will increase the inflation pressure. You running bead locks?

Yep. Damned details... :D

Lol. Still ran quicker times at whatever that dusty POS track was near Willow Springs than you ever did turbo. Either way, my last drag strip pass was probably still more recent than yours, or did you take the mid-life-crisis-mobile or Lesbo-mobile out? :D

Give me until this time next year, and I'll resurrect the SE-R to pull your doors off. Fontucky this time though. I do miss drag racing. Way cheaper than road racing.

Why do you need a year?!?! :)

Why do you need a year?!?! :)

Because I'm lazy, apparently. :D

Trying to finish this sand rail project before the desert season starts back up. I also have some home improvement projects that need doing and I'm almost done with school (freeing up a bunch of cash to boot!).

So yeah, next year... Maybe... :D
