hey guys im taking the car to the track for the first time with slick. any suggestion on warming them up? psi? rpm for launch and technique? the car is making around 360 whp turbo, and the tires are 24.5 - 8 -15 on the aluminum stocks.

 

First of all nice power, any pics of the setup? Or details at least?

Second, have you been to the track before, and how experienced are you?

Basically, slicks are really easy to do a burnout in. With no treads whatsoever, they will just side like ice when they are on water pretty much. What brand slick is it? Different brands like different temps. M&Hs like to be really hot, so I used to do a burnout until I could smell smoke and then I knew they were good and hot. MTs don't like to be as hot I'm told, though I've never used an MT slick (have used an MT ET Street though, but they're not the same rubber compound).

Some tracks have you back up into the water (good for RWD cars, bad for us) others are set up so you drive right through it. Alot of track workers will try to roll you out of the water after you've gotten in it. If you can complete a good burnout like this then fine, but you might find that you need all the water you can get and that you'll get a better burnout while your front tires are still in the puddle. Tach it up exactly like you were going to do a burnout from a stop sign or intersection, pull they Ebrake pretty good, no need to rip it off the floor just give it a good yank like you were parked on a big hill. Don't put it to redline then side step the clutch or anything like that, there is no need to be that violent with it. It usually too me probably 10 seconds to start smelling smoke. Turn the wheel side to side once you have your tires spinning to make sure they are both spinning and to make sure as much of the surface is getting hot as possible. Then as you are getting them nice and smoky let the ebrake off so you start pulling forward, as the tires get dry and start to grip you will notice a change in the noise they make and how much they pull you forward. you're done with your burnout. before going up to the line I like to make a quick dry hop of the tires to make sure they feel right. then i stage.

For your first time out you are going to be experimenting with a bunch of different things, RPM, tire pressure, launch technique, etc, so do not be surprised if you don't really get it down perfect your first trip to the track. my first day to the track on slicks ever i think i went 14.1 @ 97 with a 2.11 60' or something. later i got that 60' down to high 1.8s on a stock clutch, so it takes some practice.

for tire pressures, i'd say start out around 14psi in the tires and drop it a half a pound each run. i usually end up around 11.5-12psi as my optimal tire pressure. if i get lower than that, like into the 10s, then my trap speeds and times start slowing down.

for RPMs your first time out you are going to need to find out what's the limiting factor, clutch, power or traction. in my old NA car I found out that I couldn't launch at more than 5500rpm or I would burn the stock clutch up and then i'd ruin that run and probably the rest of the day. I'd start around 3500 or so, and do a quick slip dump. a slip dump is hard to explain but it's sortof like dumping the clutch part way but not 100%, ideally you want to engage the clutch while slipping it to take up all the slack in the driveline so you don't shock the **** out of your trans or axles and break something. 3500 will likely produce a bogged launch. if it does then up to to 4000 the next time, then 4500, etc or whatever increments you are comfortable with. the idea obviously is to find the best launch which avoids launching overly hard and either burning up your tires, clutch, or hurting your car.

it will take practice to get good and consistent with them.

 

ok i will do that. do you slip the clutch a little on 2nd or you just throw it into 2nd? i blew up a tranny on really good warmed up drag radials, so im a little timid. Ok so i am thinking about going through the water box and stopping right at the edge, then burning out. I was told if i burn out in the box, i will have some water on the mudguards that can drip down on to the track or tires and could be worse? what do you think? how did you get into the 11's on pump gas???? i mean i am sure youre using methanol. like me, but no nitrous either??? what do you think is the limit for boost on our motore b4 they break?

 

I don't have any methanol or water or alcohol injection, nothing other than 93 pump gas going into my engine. Nothing.

I've only made 3 passes on slicks in my turbo car (made hundreds of them on slicks in my NA car) so I don't have enough experience on them with the kind of power a turbo car has to tell you what to do for the 1/2 shift. I shifted to 2nd gear just like I did when my car was NA(pretty quick didn't baby it at all) and it spun a good bit into 2nd gear, once i get some more passes on slicks i will be able to tell if i should take it easy or not. i wouldn't slip the clutch regardless though, if you are going to take it easy do it with the throttle not with the clutch.

what clutch do you have and what's the rest of your setup like? how much track experience do you have? these are all things you need to consider.

what part of the trans did you break before? that can help you figure out where you need to be careful.

 

dude how much boost are you running?? you must have some timing control then to be able to run on pump gas. well i have a gt35 turbo , massiive intercooler, with dek motor and manifold and injectors, two additional injectors on the charge pipe, im sucking through the maf, should be after today at 12-13 psi. I am always a little bit under hp compared to people who push through the maf for about 10 whp????? what are you doing with that? the little gear in the differential broke in 2 nd basically destroyed everything on the way out.i ran a 13.0 at 108 on street radials, but they would spinn too. and that was at 10-11 psi. so im hoping for atleast 12.5-12.7 now with the additional 2 psi and dek motor and the slicks, and better turbo.

 

I've got timing controlled with emanage blue. I saw 14.8psi on my 11.7 run. I've got a blow through maf.

What is your piping setup like? Forward Ypipe or reverse like the PFI kit or something else? I'm always interested in seeing new setups. What are you tuning with?

 

reverse set up with custom front motor mount. i have pics on the for sale forum bc i actually have the car up for grabbs. i havea full t4 custom gt35 with a .58 q trim turbine housing. with full 3 inch downpipe and exhaust. for tuning i have methanol injection for detonation help and two additional injectors on the charge pipe controlled my microfueler. have you ever messed up any maf? you using z32 or stock maf? at what psi will motor break?

 

Never heard of microfueler, I'll have to check that out. No I've never had a problem with my Z32 maf. I don't now when the motor will break with a good tune. Hal ran up to 22psi on 116octane and also 15psi + a 150 shot and didn't break it immediately (though I don't know how long it lasted and I wouldn't exactly call that "safe" heh). There are also guys who blow motors at 10psi so it's all in the tune and setup.

 

when you going bish.. thanks for telling me

 

My bad we are all going on friday. Me streetz, 95blackmax, the other turbo max, and who ever else wants to go. I dont haveyour number luke so i cant call you.

The car was on the dyno last night. It was wierd to say the least. The car made crazy power and the tune is beautyfull. I made 393 whp at 10 psi. The car didnt like more boos bc it would ping. I need to tune it with 104 octane and put it to 14 psi that **** woould make nasty power. but i like to keep it street, so anytime i want i can hit it without worrying about the gas i have.

I think its about the motor itseld too. With the last worn motor with 15k miles the car made 335 at 12 psi. Now this fresh dek with a better turbo and the different manifold. made way more power with less boost. but the pinging came in sooner than before. My tuner tells me that the pinging comes from cylinder pressure and boost, a combination. Now i have more power with les boost, but it pings, at an earlier boost level.


i want to be able to take some timing out of the car? and also want to bump the limiter to like 7500 , what do you think? the curve keeps going up now, not like before that it would die at the end? I have a huge intercooler and methanol, i want more boost dammit..... any idea what 1/4 mile i shoul be around with 393 whp???

 

I dont think it wuodl be safe just sticking it up to 7500rpm, 7200rpm should be fine. I think you should try out an emanage so you can stick the 2-step on there and timing/ air/fuel tuning.

Judging by the power and if you can put it down (slicks) i dont see why you couldnt hit a high 12, low 13

 

dude i ran a 13.0 at 108 with the old turbo on the reg 96 engine at 325 or so whp with the street radials from bf. i ran a 13.5 with the 18 inch hp's at like 109 untuned at 9 psi which on the dyno the car was lean with about 370 whp. with slicks and 390 i better run a 12.7 or so, you dont think? i used to run 13.24's with reg tires 225/60 15 falkens street tires, so then i got the bfs and ran a 13.00, that was with only about 330 whp. so i hope with another 60 whp and slicks to be at that number , i hope

 

If I were you I wouldnt push my luck and Id set the rev limiter at 7000 flat. That should be safe. Dont go over 7k, its more than enough. I mean youre pushing like 460 HP at the crank, who cares about revving to 7500.

The VQ35 guys like to keep the rev limiter to 6600 (stock) when they boost on the stock block. Because of the VQ30's super short stroke you can go higher even with boost, but 7500, even 7200, is pushing it IMO. 7500 on a stock VQ30 is for NA guys only IMO. Only NA guys really need to go that high anyway.

 

well i havent done anything yet, but the powerband just keeps climbing, so it was a tought. i wont do it, ad far as more power, i rather be reliable , and have fun with the car even if its just for another 10 horses.390 is good hp i think.if i want want more ill just put some race gas in it and bump up the boost

 

here are the dyno's AL..

 

thanks for the help Luke. Did you put them up on the 1/4 thread too?

 

12.45 at 113 mph with a 1.89 60 ft time. first time with slicks and i was not shifting to aggressively. I was a little scared to break something. lol. Also I was used to shifting earlier bc of the old manifolds power curve. Im sure with a little more practice on the launch, and if i can take the rpm to redline and maybe powershift the car may be in the 11.99 times or so.

 

no vid no care.. LOL

 

again, you could have taken he camera but you sold out and didnt go. but you can record when i beat that 5.5 on nitrous lol lol

 

Nice work. I wouldn't count on 11s with only 113mph but you could probably see 12.2s. If you think you can get another couple mph out of it 115 or 116mph then you might be able to eek out an 11. Powershifting is a bad bad idea though. You will break 3rd or 4th gear powershifting it, i guarantee it.

How many passes did you make, you'll only get better as you get used to them. What RPM did you launch them?

 

I dont sell out, I just had something else to do. Oh yea, still waiting for that race

 

well powershifting works. bc i ran a 13.0 that way. powershifting every gear. with about 330 to the wheels. i never broke, but im sure it can break. it also does help in the et, i dont think the car would have ran a 13.0 without powershifting. I launched like at 3800 or 4k. but i was not shifting at 6500 like i should off,i was shifting like right at 6k, but thats bc i was used to the old manifold that peak power was not there at redline. The mph started at 111 then 112 then 113 on my last run. I got 4 runs in only. I think i can definitel get a 12.2 or 12.1 out of it for sure, just need to redline every gear maybe and shift a little more aggressively. what you think?

 

yes, im still waiting tooo.

 

I know it works great, I used to powershift my NA bolt on maxima to 13.4s with only 185 whp. I'm just saying that you are GOING to break 3rd or 4th gear in your transmission if you power shift a car with your kind of hp and tq. People are breaking 3rd and 4th gear with less power and without powershifting.

As for your power band you should definately shift that thing at redline, you probably are leaving a couple mph on the table shifting at 6k. Your car definately has more in it

BTW - tell Luke to stop being gay and to go to the track with you next time so he can video

 

do you recommend taking the car past 6500? i havent really checked where the rpm will bounce off the limiter? dam, i will avoid the powershifting when you put it that way.lol thats y i sold te 3.5 i was going to build, bc of the tranny issues that i dont want to deal with. any other tricks that i may be able to do?

 

I'd recommend finding where the rev limiter is on your tach in neutral. On my old car it was about 6600-6700 on the tach. Then shift it as close to that as you can without hitting it obviously.

Did you mess with your tire pressure at all?

 

no not really didnt get a chance to mess with it. i left it at 11-12 psi, felt good. i will do that next time, i mean for not going in forever i think it was an ok time. i should be able to get closer to 1.7 60 ft time though. i ran a 1.9 with the drag radial(bf's) so a 1.89 for slicks i dont think was much of an improvement. what 60'ft times are most guys running on slicks?

 

DIAF

 

Most guys run 1.8s and 1.9s. Only 3 people with maximas have gotten into the 1.7s. Mardi, Jclaw, and Jime.

 

I have several 1.7's under my belt as well.

 

I knew I was forgetting someone and before I even saw what you posted, just saw your name on the thread, I remembered you as well.

 

Good times!!! I have that turbo but with a .68 hot side, I never got to get a good run in and plus a crappy prep track I pulled a 13.4 @ 110mph on street tires. Now I have something to look forward to with the 3.5 and the 35r...

 

Awsome time bro, I would have liked to see that run, but i was few cars behind you running my 14.1. and yea, never depend on Luke to go to the track, i think his scared of it for some reason. Everytime we setup a track meet, you never see any of the NW people go, their maximas are too pretty to get a little road debris under their fenders or something lol

 

dam thats true and thats gay.lol sw is the bomb, and we aint scared. i told luke about that 5.5 on spray, thats a race thats pending...lol and it will be a 3rd gear roll....yo streetz lets get these nw people worked up. lol



3.5 on boost thats going to be nice

 

scared of the track? i dont bother going because more than 3 times its been rained out and I was just around the corner from it. So screw that, plus I dont even have this 5.5 guys number would be cool too watch. He should be at the Markham meet, we got a little place for those challenges

 

thats nice, so do i, a place called " the highway , anytime" lol lol ill be out at the meet next time....representing the south... you dont need to go to the track bc you dont have anything done really, so no sweat on that luke. we still love you

ps make sure that he brings his bottle ( full)

 

what does this nitrous 5.5 gen run through the traps. my money is on the 4th gen.

 

not sure, i think its like a 100 plus shot , or 150 or something. I havent really seen the car run, but my money is on me.lol but if not, ill go pump 104 then retune with more boost then we will do it again. lol

 

, yall talk some mad shat...

 

me to stop being a hater :attention
