hi i don't know if posting in right section but i need help.i have a 98 camaro z28 with tsp 231/237 cam stock heads,lid duals (dynomax bullets off each header no cross over dumped before axle.ls6 intake, ported tb, 3600 stall 4.10s 26x9x15 slicks.car is making 366 and 350 tq to wheels and the best i can get is a 12.68 at 109.should it be faster then this whats going on.my 60 ft is 1.8 to 1.9.there are lid stall and drag radial cars on this forum fast.why help me out

 

Sounds like the tune to me. My lid only CETA put down a corrected 328/348 at the wheels with a complete stock exhaust. I'm pulling 1.7x 60 foots with the 3000 stall and nitto drag radials. I bet a good tune would wake it up.

 

i had the car tuned are u saying the tune is not right.what with the tune is wrong

 

Something is definetly wrong. I'm trapping 110 and I'm only bolt ons w/ a stall. Get ahold of your tuner.

 

i brought car to both cartek and tune time cartek did cam and stall tune and tune time did gear correction

 

anyone eles here help me out

 

Must not be the tune then, they should know what they're doing. I don't know really, I was looking more at the 60 foot then much else. With a cam, full exhaust, gears and stall, you should be leaving harder than my 1.76 with just a 3000 stall and stock manifolds, exhaust and 3.23 gears???

 

yea idk either i got 4.10 and 3600 stall should leave hard but it doesnt it just drives out no hard launch at all

 

Are you footbraking it or just allowing it to flash from idle. I'm doing the later. I hold the brake enough to keep from rolling than mash the gas pedal on the last yellow. 1.7x four times in a row like that.

 

tried both doesnt make difference

 

Could also depend on the track altitude, temperature, and many other factors

 

NJ doesn't have bad DA.

Regardless of mods or tune the car still makes good power. Too good for those times. 360rwhp should be 113-114 and any stall with 4.10s should get a better 60' unless he's spinning, but the MPH would be higher from that too.

I'm gonna say it's a crappy, inefficient stall, that was locked on the dyno. If that's not the case then you should just get a new car and start over.

NJ doesnt have bad DA? how could you even say that being in NC? you have no clue,come race out here mid summer...

if its not the stall like you think it is get a new car and start over? great advice...

 

Don't get your panties in a wad because your **** is slow too.

What you got, 2500' DA? Wow, thats ****** horrible. Compared to every where else right now, I'd say its pretty good. I mean at 0' DA he'd pick up 2 tenths, that's still no where near what it should be.

Don't like my advice? What do you think it is? I mean it makes good power, maybe not the best for what he has, but still enough to run 11s with a 3600 stall, 4.10s and slicks. I mean, obviously I don't think he should get rid of the car, but I really think the problem is the stall or failing transmission.

I mean he could have pulled a spark plug wire loose since he had it dynoed. I guess he should check that too, but i'm sure he would have mentioned that.

KillA89Z: Is the car running the same as it was directly after the tune? And what brand of stall?

Jon

 

don't take the advice about getting a new car.

MPH does seem low.

Sometimes a tune up can make a ton of difference. Change plugs, plug wires, fuel filter, inspect air filter, clean MAF with non clorinated brake cleaner.

Something could have happened b/w the time it was dyno tuned and when you took it to track.

 

dont start running you mouth because you cant handle my criticizing,big deal my **** is slow right now because of problems but this thread isnt about my car its about his so stick to the topic and yes when you live in JERSEY 2500-3550 DA is bad. im sure he might agree with this BUT <WHY THE **** WOULD I CARE ABOUT THE DA EVERYWHERE ELSE WHEN I LIVE HERE IN JERSEY AND RACE HERE, ITS NOT MINE OR HIS PROBLEM.... do you even work on your own car or are you another keyboard mechanic that gives out advice based on info you learn from the guy who does the work on your car like 50% percent of this board?.....now back on topic....


first off if anything i would ask if he went to cartek and tune time before this pass was made and wether or not he told the guys at tune time cartek did his main tuning, why you might ask? because there is bad blood between them( saw it firsthand) and from the shady things i have heard from friends who went to them i wouldnt be urprised if they screwed with this guys tune...

i would then go back to basics with the testing the free/cheapest things possible like checking the compression,plugs/wires/fuel filter before throwing exspensive parts at it like a convertor

of course it would also be good to see his WHOLE timeslip so it would be easier to tell if hes losing power somewhere along the way or throughout the entire run. ,maybe slipping trans depending if all the numbers are close,meaning his 1/8th converts to his 1/4 etc...
also does he have a built trans? did he put in bigger injectors? that exhaust without a crossover could also be hurting him a bit too. the car has some power but i dont see it being enough to need the exhaust so free flowing....

pull out a few plugs on both sides of the motor and take a look at them

black- runnning too rich need a re-tune, possibly a leaky injector or two
light brown- tune is near dead nutz
white and very little brown- running dangerously lean, could be low fuel pressure,plugged fuel filter or also a bad tune


i would then possibly call cartek and make an appointment to make sure the tune hasnt changed on you after going to tune time....

 

Yea you should definitely be faster. Im willing to bet something has happened since you had it dynoed. What was your 1/8mile et and mph?

 

If he has what he says, then he would have to lose 50+ hp to run the times he's running. I'm sure he would have mentioned that. On the other hand he doesn't really say much about the car and he has 2 or 3 other posts with the same topic in other sections.

He needs to be more specific when he posts, if he expects to get answers that aren't all over the place.

Jon

 

what kind of specics do u need im posting everywhere to get a answer.do u think they would **** with a tune because i brought it to to different places im going to pull a plug tommrrow and il let u guys know what it looks like

 

Show us everything about the car. Show us the plugs, ET slips, dyno graph, A/F ratio of the dyno. Details of the car: mods (brand), set up, man... details.
