I know the 12a is 105 hp and '83 GSL weighs about 2345lbs. I was wondering if anybody timed their '83 GSL on the 1/4 mile and your time from 0-60? Stock motor if possible, thanks!

Mr. ImportGuy

I thought the 12a was more like just around 100hp (not that 5hp is a huge diff. though).

I used to count in my head what my times were, and in my bone stock 85 GSL with 215K miles and unbolted exhaust (cats were plugges so I just loosened the bolts), I could go 0-60 in 10 seconds. 14 mile I counted out ad close to 14.5-15 seconds using the odometer on the dash.

~T.J.

PS - My 83 GSL with SLIGHT weight reduction and all the mods in my sig I count 7 or 8 seconds 0-60 every time. Not a bad improvement . I havent run a 1/4 mile yet to count it out, lol. I need to start going to tracks, and I wanna dyno my car too, lol.

SilverRocket

Lol, you must count very slowly. No offence, but you know how optimistic that is right?

Vubonic, a stock GSL will run about a 17.

From my experience with my GS:

RB exhaust and some minor weight reduction will get you in the 16 flat range. Some extra minor things (ie. electric fan, emisssions system removal, ignition advance, playing with the carb a bit, etc) will get you running about a 15.7.

Add an aftermarket carb, fuel pump and regulator, and do some more weight reduction. and you're looking at 15 flat. That's pretty much the limit of the stockport motor and a car that still has an interior, a passenger seat and a stereo lol. If you want any better, you'll need porting, forced induction/nitrous, and/or a more focused drag racing setup.

Did you miss the part where I said the exhaust was unbolted? I.E. close to open headers?

~T.J.

PS - Also, that would be counting fast to get 15 rather than 17, not slow .

sirex

stock is listed as 16 seconds

Stepdaddy

so 15-17 secs is just about right..right?

SilverRocket

LOL... so what?

1) Uncorking the exhaust isn't going to help that much when you're still bottled up on the intake side.

2) stock exhaust manifold with unbolted cats (as I understand from your post) is not headers

You aren't going to run 15 seconds with your mods, end of story. No offence.

LOL!!!!

How do you figure that??

Think about it dude - 15 is a smaller number than 17 right? Hence less numbers in a given period of time - hence counting slower.

If I said I could run a 2 second 1/4 mile, would that be counting fast or slow?

SilverRocket

Not for the 12A cars it's not.

Sure, give or take a couple thousand dollars in mods lol.

thorin

owned.

Vubonic

^^^^ LOL How do you guys post pictures right in the thread???

zookeeper

**** T.J. - you should be counting "0 - garage" times!! (Did I say that? Shame on me!). Kidding, just kidding...

BTW - I like your new avatar, very apropos...

Haha, too bad I dont park in the garage...I park outside it .

Depends on how long you wait to start counting during the race . Thanks for the correction though...I dont know what I was thinking, lol.

Oh yeah, and I was damn close on the 0-60 time (I got 10 seconds, Road and Track got 9.7), which is why I was thinking the 15 was right too. Anyway, I didnt mean that I had open headers, more just that it was open exhaust. I have just always use the term "header" and "manifold" interchageably. As "header" is short for exhaust header, which is the same thing as an exhaust manifold if you ask me. Sorry about that confusion.

~T.J.

PS - Silver rocket was righ, as R&T got 17 seconds (17.1 actually) for 1/4 mile, just for everyones info.

PPS - From dictionary.com

Header:
A pipe that serves as a central connection for two or more smaller pipes.

Manifold:
A pipe or chamber having multiple apertures for making connections.

Basically the same thing, which is why I use it interchangeably. I'll just be more clear next time .

Theres no way in hell a stock GSL runs 14.5
A GS is probally 50-100 lbs lighter,all first gen 12A 7s run stock in 17s.

With the mods I got I run the best time of 15.3 on a non ported 110k engine

I have also took my car to the dyno but the results dont mean **** tome cause the guy running my car drives a Honda and didnt know to take the ****** to 8 k he stopped on the first run at 6.5k and that showed 104 rwd hp 98 flbs tourque

When he ran it again he didnt go higher than 6 k cause they said I was running to lean,anmd the results were worse..

I ran on the first pull 104.5 RWHP and 98 torque
and this SI ran 107 but my 1/4 times dont match with my pulls,

If you guys never been to a dyno,manufactor specs dont mean ****,they mesure it at the flywheel.

Stock specs are,
Output(hp): 100bhp @ 6000 rpm
Torque: 105lb-ft @ 4000 rpm

Ok that guy who ran there with the SI,they come stock?160-165? and he pulled a 107hp,look at his lost.

Im not ported yet,and the car if far from properly being tuned,Im satisfied for what I have in the car start to finish,For what I payed for my car and what I have in mods,I have about $900. and run 15s I hit 15s 3 times im hoping to take it to the track this week but my kids are sick and now so am I,I got a couple fuel cooling tricks and was hoping to get it into 14s,im just tring to go all out untill it gets ported,





BTW estimates and G Tecs dont mean **** untill you take it to the track.

Is that the rotor oil cap you sell?

~T.J.

SilverRocket

But you see, the thing is that 0-60 and 1/4 miles are somewhat related. There's no way in hell a 10 second (or 8 second for that matter) 0-60 is gonna be anything close to a 15 second quartermile. A 10 second 0-60 is a 17-18 second quartermile as far as I know.

If you're running a 15 second flat quartermile, you're likely doing 0-60 in the neighborhood of mid/high 6's - remember that.

Seriously, if you really want to know what you're running, head to the track, but don't be surprised if you're disappointed lol.

Haha, I know my cars slow . I plan on aftermarket intake and going turbo as soon as I can afford it .

~T.J.

SilverRocket

Hey, I'm not trying to say anything about your car man, I just didn't agree with the figures you were talking about ... it's all relative of course - there's lots of guys with crazy muscle cars that will think we're slow as hell no matter what we do. And at the same time, there's tons of meatheads in Honda's running 16's who will think we're fast as hell lol.

FB's aren't really about raw forward thrust anyways...

The only reason I started up is because the dude wanted to know what 1/4 miles were possible, and I wanted to clear things up a little.

Cloud

I think my stock 85 GSL would be lucky to run a 17 flat, after I give it a tune-up. I plan on taking it to the track anyway...at least to let my brother's street-ported 85 GS look good!


I have a long way to go before i hit tens, eh?

To whoever said "15-17" seconds....! Do you know how much people spend to drop a tenth or two? Two seconds is FOREVER in a drag race...I was ecstatic to make my Mustang drop from a 14.1 to a 13.70, lol...

WackyRotary

enlighten me, what is a fuel cooling trick?

SoRRoW

Thats the one I can get,I dont "sell" them,Its the same style they sell on a rx7 site but not the cost.Its unpolished and still had paint on it I got to get out,if you can see a little in the corner.

SoRRoW

If I remeber right,a stock Mustang is high 14s,BUT look at the cost of the car,and look what kind of cash you put into a rotary and watch your gain.

Theres Honda guys who spend 5-8k on swaps with parts etc,who get 13s and think thier **** is fast.Put that money diffrence in a rotary and the power diffrence cant be touched.Keep it on a 12a.


Last time I went to the track,I lined up with a 93 Touring,and they guy is on this site.When I lined up with him I hear ******* on the side say look at that POS,talking about me and saying slicks are suppose to be in the back cause my tires in the front are almost bawled,Well I killed that car o the launch and we was side by side all the way down I can hear his BOV at the same time I shifted and I was shifting at 8 k and I think he was probally at 6k with 12lbs of boost he said he was running.The out come was 15.7 him/15.9 me.

I dont care what Road and Track/SuperStreet Mazda OEM specs say,The driver makes the car,You can have a 400 hp car race a 200 hp car its up to the driver If you cant drive or know when to shift yoru fucked,

You CANNOT drive a rotary like you drive a Honda,he more HP is higher RPMS,My rev buzzer kicks in at 7 k my shift light kicks in at 8.

Fennix_sr

lets change the subject, how fast 0-60 you think a gsl-se could do what what about a 1/4 mile?
