First Time at strip. at IFO

[boosted99_420]

Ok so i went to IFO in shreveport,la with a bunch of people and decided to run my GST for the first time. So i started by lowing my tire pressure to 18ish and did a pretty darn good burn out. Launched at 3k RPM to hopfully not spin (high was 58) And didnt spin very much and got a .211 R/T, 2.6 60ft., 10.046 1/8th, and 15.301 @ 91.73. This was actually within what i was planning to run.

Mods:

Greddy Hard IC pipeing (type S BOV)
Injin Intake Hard Pipe
14b ported turbo (10psi)
MBC
Full 2" exhaust
264/272 combo cams (nice lope at idle after its warmed up good)
everything else is stock

Car is 100% UNTUNED!!!! With a clutch that does not engage until its on the floor or it will slip.

Thats a decent mph for only 10psi. Get that 60' down to a 2.1 or so and you'll be in the 14's. Once you get your clutch sorted you can ###### bump the boost upto 14-15psi and gain a few mph too!

 

[UnderPrssureDSM]

Adjust your clutch free play to get the pedal off the floor.

 

[boosted99_420]

the guy i had do my clutch said the accumulator is bad on my trassmission and thats why i cant adjust it with out slipping. But ive been reading up on here about a mod to go strait from clutch resivoir to the slave cylinder. Im planning on doing that soon.

 

[sexystover]

if u got your 60' down to a 1.7 you could take off 1.2 seconds in your 1/4 time

yea im workin on that imma try to get a friend 1st gen gsx off him and say to hell with fwd

Just be prepared, in your search for the perfect 60-foot, to save some money for your new upgrade... clutch.

It took switching over to an ACT2600 for me to get a 1.598, but that's just me.

I find it kinda weird. With those mods I thought you should of killed some more time. I very curious because I see some people with hecka mods hit like 13's while people with hardly any mods hit better times. Always bugs me I guess when you get injectors and a tune you'll be high 13's or low 14's... good luck on your next run.

Atleast you got your first time to the track out. It'll be my first time this week. I'll keep ya posted. Mods are up to date, pray for traction.

Yea fuel, and no tune is holding me back especialy no tune. Oh and a newly found crack in my smic I discovered yesterday very ### so imma do a temp fix on it or sell car and get a gsx or tsi awd. I could have hit 14s if I didn't baby first on the start but my tires are old, over sized, and have no grip, the guy I got the car from was an idiot.

 

[Dyesuperman]

Not bad, weird mph though. I ran a 14.6 @ 98 in my old gst with stock t25, crappy hard uicp, 3" turboback, and on 15 psi. That 14b was probably pushing just as much air though at 10psi. Oh, and some tranny problems, I bet my 1-2 and 2-3 shifts took a whole second at least because they did not like high rpms.

 

[97 DSM Gs-T]

wow 15.3 that seems kinda high i ran a 14.3 on the t-25 with not that many mods back during imports vs. domestics

 

[bastarddsm]

NO. It doesn't work like that.

 

[Dyesuperman]

NO. It doesn't work like that.

Woah, getting out the caps here, you must be pretty serious. I was under the assumption that the 14b flowed more air, or does if just keep power throughout the rpm band and that's it?

 

[bastarddsm]

Here's the deal: The volume of air moved is primarily controlled by the parameters of the engine. Think of the engine as a restrictor: No matter what is supplying the air, at 10psi only so much air volume is going to flow.

Now, it gets tricky when you start pushing things: for example 20psi on a 14b, is different than 20psi on a 3586r. Here's why: Everything required to support the bigger compressor is better flowing, basically "opening up" the restrictor. Its not the compressor wheel that causes more air volume to flow, its the rest of the system that presents less of a restriction to the flow.

It gets even more complicated. We havn't talked about air mass yet. When you look at air temp you start to see air mass. The higher the temp the less air mass per volume unit, also the less efficient the compressor, the higher the temp. So with a 14b being slightly more efficient at a given volume flow and pressure, it will move more air mass per volume unit.

But the effects of this are going to be pretty small. <10%

So with the T25, and the 14b being kinda close in size, 10psi on a T25 = 10psi on a 14b = 10psi on a 16g

Yes. It's when you get into the higher boost levels that the 14b starts to flow more than a t25. For instance, 18psi on a t25 does not = 18psi on a 14b. At 18psi, the t25 is running out of steam, is operating inefficiently and raising intake temps. At 18psi on a 14b, you are still in the efficiency range of the turbo. Thus moving more cool air, which is more dense than the hot air being pushed by that t25 on 18psi, and creating more power.

i can hit 14s if i wanted to blow my tranny out or burn up clutch i just dont wanna go through that again

NO. The problem is that a t25 can't keep up, and the waste gate ends up staying closed trying to hold the boost. This creates restriction that limits the volume airflow.

Really the compressor efficiency difference is small, and the difference in mass airflow because of it is even smaller.

To the op, if your selling the car based on the time you ran, i wouldnt just yet. Get your clutch issue figured out and the boost leak from the smic is killing your power. That trap speed seems very low for a fwd with those mods. Fix those issues, practice your launch, and give it another go imo. Im sure you will be much happier with the car then.

Also look into tuning, launch control on a fwd seems like a must have.

im sellin because i want something very few people have in my area a 1st gen GSX, a Colt GT, etc. something uncommon . And i am looking into a tuning shop if i dont sell it.

Same reason I was able to defeat 1300s with my 600 at the track. Driver/Rider ability.

Seat time is what you need dude. Thats what going to pull those times down.

Bingo

decided to keep gst and buying a 1990 tsi awd shell. Got ecmlink v3 lite in the gst now and i am staying about 2 cars behind a know 13.4 sec 240sx so im guessing im in 14s now going back to track soon i got my launches down to where ill spin but ill catch traction as soon as i let off and get back in gas. new times coming soon.

 

[my dreamt dsm]

Keep us posted. I'm very curious.
I finally learn how to launch on bigger tires and lighten flywheel. After a few runs the big16g is going in, finally.
