Hey guys I got a 88 GTA yesterday with 350/a4 and did a tune up on it, cap rotor wires plugs fuel filter oil change and ran it on the gtech and ended up with a 15.8 at 91 mph, shouldnt it be more in the 14's, I also had a mid 7 sec 0-60 run. What else should I try to get it up to factory specs? Tips would be gladly appreciated!!!!

Thanks,
Mack

 

Altitude can have an effect on the times. What track and where is it located?

For reference, my 86 Trans Am LG4 305 5 speed ran a 14.94 @ 92mph and my 88 Formula 305TPI Auto ran a 15.2 @ 89mph. I haven't taken the Formula to the track with the 5 speed yet, will take it later this year when it cools down a bit.

 

Kinda funny that the guys w/ the really "loud" screen names like fordasskikr, vipereater, etc. run times a Honda could kill...just an observation.

 

I didn't even notice he said G-Tech.

 

Gtech may be off a little, but I would contribute your runs to altitude.

 

Exactly. Btw, how many miles on your car? Is it stock?

 

I think there is about 100k miles on the car but it's got the digital dash and its kinda flaky so I'm not sure, Im in kansas and not sure of the altitude but it is almost nothing. The screen name just matches my email but dont see why you must talk s***, but every car starts off stock, sorry I'm just a little sharper at picking names than you

 

Its a post, simmer! Just make sure you don't race any Fords that pull up next to yoU!

 

Along that line of reasoning, the children w/ the NOS stickers all over their Toyotas are "just a little sharper" at bodywork too.

Running that slow with a "fast" screen name invites razzing, get fast or get used to it.

 

Yea. cut the guy some slack,after all he has like 5 posts. Not everyone has the time, resources or money to just drop a LS1 in or a t56.You must be a Kurt Busch fan............just an observation.

 

I've noticed that there are a lot of guys on this site that jump down peoples throats right away! A lot of us are younger and not as knowledgable, thats why we ask questions!

 

Join the 2.77 club like me and check your rear gear.

 

well I would say those children in supras with NOS stickers have more than enough to chew you up and spit you out and I have had this name for a long time, matches my email and had it for my 64 chevelle, you are more than welcome to try and see anything but its tail lights if you would like, and as i said I just bought this car so maybe you should step off a little bit, if you havent got anything positive to contribute, keep your mouth shut, the way you act it seems as if you are the child.

 

My Taurus is stock and runs better times. :P

Relax, Kev is just razzing, pretend it's the shop and one of the guys is giving you ****. Your relative car to this board is slow, if you frequent many boards of various contextually distinct bases pick a more generic name... otherwise your mates will razz you.

Notwithstanding of course that he made a general observation, not a directed comment.

 

This was probably not the first time you've been wrong.

(I didn't even know who that was until I looked him up just now. I quit watching NASCAR years ago when it turned into a racing version of pro wrestling.)

 

annnnd......probably the first time you've been correct

 

 

what a bikering post you guys made. who cares what his screen name is. it doesnt matter. its like everyone wants to find something to flame the next about. this guys wants to know about his car he doesnt care what you think of his name. now back to topic. every car runs differently when i searched for what a stock GTA ran it was usually anywhere from a mid 15 down to a high 14. my car has run a 14.8 with the following mods listed in my sig. some guys ran this stock but this can be contributed to many things. altitude as previously mentioned, engines condition, rear gear is also a big factor. go out check your rear gear and go from there. now hopefully i didnt spell anything wrong or anything to start a flame war on me....seems like its that easy.

 

wow! GTAs are slow.... hahaha! I just figured i would continue the flame trend. Cut the guy some slack, this is a tech board, not a place for me to say how much bigger my...... well you get the point

 

I have a completely stock 88 GTA, with a 305 TPI, auto trans and 3.27 rear and run a 15.56 in the 1/4... So something is wrong with your GTA

 

the fact that the car has around 100k, so thats alot of miles on an engine and tranny so its not going to run the same times as it did off of the assembly line. change oil, get a tune up, put 91 w/ octane booster, check gears ....you know that ol' stuff. good luck with it!!

 

15.8 seems a bit slow---just ran my 91 formula 305tpi and came through at 15.9 and that was with 95+ degrees outside. What gears do you have. 2:73's are holding me back

 

I have 115K on my engine without a rebuild and I did a 15.56 with my 305 TPI...

Maybe you need a good tune-up like I did? Spark plugs, wires, air/fuel filter, cap, rotor, PCV valve etc... Get your injectors rebuild at cruizinperformance or something like that....

 

this is a tech board and not a place to act like children. Leave the immaturaty at the playground. Btw g-tech times are not exactly accurate, best thing to do is to take it to the tracks and see what it does.

 

Your mph sounds about right. My GTA ran a 14.91 basically stock with a trap speed of 91.4mph. I'd say there's a few things for you to look at:

• Not sure if your tune-up included checking the timing. Set to 6* BTDC (or more if you want to go beyond stock, just be careful).
• Get a K&N.
• Your rear gears are probably 2.77 or whatever it is, which translates into less torque multiplication (I think that's the right term) at the wheels.
• My friend's G-Tech said his car runs high 14s/low 15s when he basically walks my GTA that now runs 14.21. Go figure.
• Take it to a real track and get some real numbers. And practice getting a good launch before you go there otherwise you'll look like an idiot.
• Are you power-braking? Hold the brake down with your left foot and press the gas up to about 1500 rpm (or however high you can get it without spinning the tires).
• One more thing, just let the tranny shift on it's own.

I think these will help you drop some time off your 1/4mi. Hope this helps, post some new numbers (incl. 60' time and trap speed) once you get to a real track.

 

U know,

heres a stupid one.

Have u set the timing to spec taking care to follow the proper procedure, ie disconnecting the est wire?

Also have u gone thru the basics, like plugs/wires/fuel filter/air filter/tested fuel pressure/ohm the inejectors

might be wise to do , at least than u would know if it is vehicle related ro driver related

later

Use the GTECH as a tuning aid, i/e make a mod, nore the difefernces. Once you do a few things, then take it to the track and get an idea of GTECH vs Track time...some report GTECH pretty much right on, others report GTECH being high or low in ETs and MPH.

But, good thing about a GTECH is if you use the same road, set it up the same, it will be a good monitoring device for mods you make and tuning you do.

Sorry, it's too early for me to fan any flames this morning. Maybe later.

 

Even with the Mileage on it ...I don't see it being the reason why . Mine was a 305 5 speed with 3.08's pulled a best of 15.1@ 93mph and it had 227'000km's of hard mileage and the tranny was on it's way out in a bad way .

 

Just an idea, but maybe it's your start that’s affecting you. When I first got my 5.7 Formula, I wasn't used to the torque. I either gave it to much power and spun em. Or I gave to little gas and didn't do much. It took me a lil while to get used to the increase of torque over my old car.

Just my

 

considering the original poster hasn't replied in about a week, I think you guys scared him off... lol

 

You no whats funny is i have a gear ratio of 2.59 in my vette. I'm sure it's in the mid to low 13s too. I think my 700R trans tranforms the 2.59 to like a 3.23 in first gear. Damn know that I'm thinkin about it I have to much gear its got a wild top end though . Wonder how she'll run with some 3.55, I need suspenstion first though? anyway just bord outta my mind and wanted to post something. But yes I think you'll scared that new bee, and he might be trading in that GTA for a honda civic with plastic spinners.

 

you didnt scare me at all, I just figured their wasn't any point wasting my time arguing. I did get the car runnin quite a bit better by pounding out the cat which must have been plugged. I've been getting around 19 mpg with it which seems pretty good considerin how I drive. You guys must think I just now got something with those round things called wheels but I'm real knowledgable for my age and maybe you guys should try to help instead of discouraging someone like me new to the 3rd gens, because others might buy a honda, they are alot nicer in those forums to newbies.

 

I offered good advice, where my love?

 

Lol yes I know you did, quite a few of you left me good information and I thank you for that very much instead of trying to be a smart ***. Thanks for the help to the ones who tried to help

 

why would adding 91+ octane booster help?

is there any vin #s or anything to look for to find out what gears are in the back beside the obvious spinning the tire and counting

i heard it was in the back by the spare or something?

 

i know how you feel, i was just recently new to the board and i got flamed too because i was young. dumb thing is i am pretty knowledgeable about this stuff too. i guess alot of the guys dont understand that kids are getting into this stuff these days, and arent like most of the other kids who are ricers. good luck with the car man.

and by the way, everybody suggesting a tune up, read before you post. the first thing he said was that he changed out wires, plugs, cap, rotor, filter, etc.

 

sig says my time on a basically stock l98...

i knew how to launch my car and it was perfect temp and everything. It was my first run ever on the dragstrip i even redlighted it first and i was amazed by how well i did even being nervous.

honestly its all ur 60' time that shows how you did...people complaining running low 15s with l98s normally have like 2.3-2.5 60' times...launch is all you gotta worry about on an automatic. Let it shift by itself.

My car wasnt abused when i got it at 103k miles i could tell by the owner and just no signs of it. I got lucky in a way and my car has been a blast for me without any real problems.

But anyway...im a kid too, you gotta learn to take half the abuse you get when your new at lets say a job, school, or thirdgen.org

Being a peon at a shop changing oil, your at the bottom of the barrel gotta learn to take the ****.


also side note: ZZ4 86 Z28 have u run ur car at the strip yet?

 

hey, sorry to go a little off topic, but steve, are we meeting up anytime. i really want those taillights you got, and if you would be nice enough to show me your airbox mod, i have been wanting to do it, but i cant justify doing it without seeing it beforehand. just pm me or something.

 

fordasskikr, honestly, how many times have you been to the strip with the car? Alot of times people just go a few times, and think that is as fast as they can go. Believe me, I am guilty of that one myself a while back. Get some sticky tires, and go to the track all year long, and try to get the best times you can out of your car. Improve the 60fts, MPH, shiftpoints, etc. Ill bet that car will go a few tenths, or more faster.

 

Sorry, I just saw G-tech in the post. The car will probably go faster at the track anyway.

 

yea there is another way to find out your gear ratio. lol Pull the cover and count the teeth on the ring and pinion, then divide

 

I have seen some G-Techs recalled for bad programing inside I would take it to the track to get some real numbers. Than go from there on better times.

 

again i wouldnt rely on the GTECH

get some more practice..

on the street, ur calculated 1/4mile time will be less cuz no car can launch as well on the street as they can at teh strip. the strip has a prepared surface with rubber and VHT LOL helps ALOT

ur trap speed of 91 is abit low for a stock L98. but again, Gtech could be wrong

u need to get out to a real track and practice alot. you'll get better as u go along. it happens. no one runs their best run their first time....

so go to a real track with some decent weather and see what happens.. then go from there

 

Don't gtech your car going up a hill lol
15.8 is ridiculously high times, even for a 305 TPI. I went 14.5@97 MPH with my IROC pretty much as I bought it (bone stock) and then 14.2@100 MPH when I gave it a tune up. 350 TPI and 3.27 9-bolt. It wasn't at all hard to beat LT1s and hold off LS1s until the top end (about 70 MPH) when TPI just stopped breathing. You should be running mid-low 14s with a healthy 350 TPI and 3.27s, 14.6-14.8 with 2.77s. At any rate, give the car a tune up (plugs, cap, rotor, wires, oil), check timing and adjust as necessary, make sure there aren't any leaks (vacuum, exhaust or manifold), take a look at the computer and make sure some smartass hasn't put a hyperjunk chip in lol. Also get good tires and launch it. When you cut a 2.0 60' like I did, you can expect mid-low 14s from your STOCK 350 TPI iroc.
the other thing you can do if all else fails is check the 8th digit on the VIN. If it's not an 8, it's not a 350 and your times would make sense for a 305. I knew more than a few people who thought (and were told they were being sold) a 350 car, when under the hood was a 305 TBI or a 305 TPI (matched the VIN) which made sense for them being so slow. This is also a reason why the 5.0 guys think they are so much faster; a bunch of misinformed, newbies with 305 cars tell the fox they are running it's a 350 TPI and get waxed

 

Keep in mind the GTA's were The heaviest 3rd gen made...

That being said i would expect a good running non abused 350 tpi car to be atleast in the 14's.

Double check your cap and wires, maybe somethings crossed or your only running on 7 cyls. Gears most likely need to be addressed 3.27's atleast would be a good idea.

The L98 stock exhaust is horrible, headers high flow cat and 3in piping would be a good idea.

Practice your launch! If you can get off the line without shredding the rubbers that will make a huge improvement in your 1/4 time.
Oh and Mack welcome to TGO and dont worry about the guys talking smack, its pointless to argue with them, and for every little kid on here spittin theres someone with a ton of know how and the willingness to help a stranger, That being said good choice of cars, hopefully it is in fact an L98(not an LB9) and just out of tune for some reason or another...

Good luck

 

Sounds like he needs to change his screen name to 'yugoazzkikr'

 

lol

Anyways...15.8@91 is pretty mismatched. I ran a 15.5@88 with my stock/cat-back 305 and a 2.2x 60'.

A 91MPH trap should be a mid-high 14 with a good 60'

What were your 60' times....2.5? 2.6?

 

15.8 is slow. Honestly go to the track and get "real" numbers, GTECH doesn't cut it. You will be doing yourself a favor to learn to run at a track.IMO

Conrad

 

damn I used to think stock 5.7 TPIs were *sorta* fast... but they seem to get basically 15.0 seconds on average...

that's only slightly faster than the 4thgen v6...

at least you guys are 3 whole seconds faster than my old v6...

 

somthing is wrong with the car or the g-tech my gta 350 tpi ran it on a g-tech the other day and ran a 15.5 at 92 mph then egine light turned on like min after i ran it and i hardly made it home and it read that i had 163 hp im getting sick of that engine light!!!!!!!!!!! i should pull the engine and just put a carb set up and remove the whole computer!
