this past fridays, i decided to run my Turbo II at the track for the first time in my life... been picking races on the street, but never ran with the christmas tree... anyways, this was a last minute decision...since i found out the that night was the last street races of the season at that track... the car is in need of new plugs n oil change, but i ran it anyways...i got 3 runs in... running 1 bar(14.7) with 93 octane...i have stock 16" with 225s in the rear(didn't let any air out) don't laugh, it's my first time in front of the tree....

RT 60' 1/8 1/4 mph
Run 1 : 0.934 2.513 10.098 17.577 44.40

Run 2 : 0.958 2.462 9.929 15.174 93.53

Run 3 : 1.101 2.178 9.478 14.699 93.91

now to explain the first run, i had a terrible launch just like other runs..well, none at all... i didn't want to break something with a hard launch.. n when i shifted into 3rd, i went into 5th so i shut down around 1/8 mark and coasted across da line...the last run, i launched with lil screechin of the tires..thus the several tenths off my 60'...

i think after some maintenance on the car and some practice at the tree, i can get into low 13s or maybe even 12s... people that rode in my car believe that it's a 12sec car.... o another thing, the track i ran at is known to be pretty shitty... nitrous 5.0s were running 13s 14s mostly...i plan to run at MIR (Budds Creek, MD) in a wk or 2 after some maintenance on the car.... any advice for a beginner track racer??

Here is my first and only run at the track a couple of weeks ago.
What kind of tires are you running on the rear?

 

I got a tip for you that will shave at least half-a-second off your times

when you get to the light and stage put clutch pedal all the way down..then rev to 5-5000 rpm start letting up on the clutch till you almost feel the car move when the last yellow light hits
let go off the clutch holding the gas pedal where it is after your wheels sqeel floor it.....

I 1st tried putting the clutch all the way down reving to 7k rpm
and lauching
which made me spin tires in 1st
low 15's

then my mech told me what im telling you
and I did a 14.4 pass@ 5 PSI

 

Hey, not flaming or anything here.

Does your car seem to run smooth and strong, and has good compression? Stock turbo'd TII's at 10psi and less at full weight (IE 10AE with functioning AC) can run 99-100mph traps. One car has a DP, TID mod, and merely creeps to 10 psi, as in through 1st and 2nd it isn't making 10psi or the power that comes with it. ANY turbo upgrade with necessary fuel at that point should shoot the thing up to 102mph+ if it makes 10psi in all gears, and at even the lower boost pressures from your sig should pick up much from there. IE you may be off 10-12mph at the traps from where a car with your mods easily could be. Was it terribly hot at the track?

No doubt, the top end rush and pull your car should feel like some high 12 second cars. I imagine my statement would be that it felt like a 105-108mph car, as the launch, driver, and tires can take a 13.4@107 and make it a 12.9@107.

 

you talking to me ? or fc3s_gtr?

If me
Ill try to make sense of what you stated

Temps where like 85 degrees

Ill give you a full description on my car

Its a 88 GXL with a 88 Turbo II motor midly ported
it has a 3" downpipe that runs into a 2" pipe
with a single NA muffler in the middle of the car(hence lack of boost) Note: I never once hit fuel cut... I have no fcd
It has the stock TII intercooler but no TII hood
HKS Intake (the green one)
that is it, no other mods what so ever.

Tres are pirrelli's 205/50/15's
not slicks nor drag radials
just your average tires

I have a boost guage and my boost never exceeds 5.5PSI
so 14.4 for me is very good for what I got (or lack of)
I have seen MANY MANY TII's at the trac over the years
with more mods then me
and run near my times or even higher
I once saw a bone stock 87 TII run 14.9
after many runs (most was mid to low 15's)
but he had real big tires in the back


if you think a stock TII with basic mods(at stock boost) can run 12's you very mistaken

 

Heck Kabooski, your car GETS IT for what's in it! I was talking to fc3s_gtr. Didnt' I mention the turbo upgrade he has and the amount of boost he ran?

How's your car work with the stock TII IC, front mounted I'd bet? Cool!

Agreed, 12's definately takes more than just stock boost....But not much more than a few basic mods!

fc2s_gtr's Td06 and fuel system should support the trap speeds 12-14mph faster than he's running, and with a launch should be high 12's/low 13's. 110mph TII's with a good launch often run 13.2's or thereabouts.


SNIP
--if you think a stock TII with basic mods(at stock boost) can run 12's you very ----

 

yep he should have the power to run deep into the 13's if not 12's

 

i know the time i ran is terrible in relation wid the mods i have... several factors play into it... first, this was my first time running at a track.... second, the track itself was pretty shitty...many of the blown 5.0s were running high 13s or 14s.... third, i was being very careful about launching.... only time my tires spun was on the third run for a sec or 2.... fourth, i pulled the plugs and saw that they were in pretty bad shape (stock NGKs about 2700miles old).. i cleaned them the best i can, but didnt have time to go pick up new ones... and the car needs an oil change....
the motor only has about 4000 miles if that..... now i haven't boosted over 14 psi with the new motor yet....
i'm sure with a good launch, i can drop half a sec at least..... with some colder plugs or even new stock ones, i can drop couple more tenths (yea, the plugs looked pretty bad) at the same boost level... now with new plugs, i'll probably raise the boost to about 1.2bar=17.6 psi or maybe even more depending on track conditions... that will defintely drop some time...
when i said that my friends believe it's a 12sec car... it wasn't at the track.. this was when i was boostin 14.7psi+ before the new motor...and it was during colder season(feb-mar)...
believe me, i was pretty disappointed at the times i ran, but i realized it was my first time... and the times improved each run.. although my RT didn't... so i should be happy...

ps- i run BFGoodrich 225/50zr/16s in the back n yokohamas in front

 

It was the trap speeds I was going off. You can baby the launch, cut a 3 second 60ft time, and still run close to the same trap speed as if you cut a 2.0. Unless a shift was really botched or the car was hesitating, that thing ought to run 95-99mph. Running right on 10psi 102-103mph isn't out of the question.

94mph would indicate something is funny.

(Stock full interior heavy 10th anny ed TII with TID mod, DP boost creeping to 10psi in 2nd and 3rd can run 100mph traps.....)

 

faster 7,

wat kind of problems could it be if the low trap speed wasnt because of my lack of drag skills? only mechanical thing i can think of is the foul plugs....

When I first ran my 89 turbo II the best I could manage was a 15.5 but my trap speed was right down to about 87mph so I knew something was wrong . I later dynoed the car were it made only 147rwhp, it turned out my waste gate was cactus and the car was only running about 3psi . After I got it fixed the car is now putting down 220rwhp @12psi I haven't had the car back at the track yet but it should run into the 13's hopefully. If I were u go and get your car dynoed to see what it's putting down cause your trap speed seem pretty low even with a bad 60ft.
