I already said no stock L03 would do 14s on the theoretical street racing board. If I am only running 14.1 with everything changed on my engine besides the heads, then how can he just slap a muffler/cap/rotor on and run a time as good as a L98? I spent thousands just to get it to run a 14.1. I could have just used that money and built a 12 second 350! He should be in the mid/high 15s shouldn't he?

Your times are pretty crazy for the small amount of mods you did! Do u have a 0-60? I have never seen an LO3 run a time like that with just those mods. And I always thought the WS6's came with LB9's or L98's as well. But maybe I am wrong.

open until we found out how he really ran that time, and what engine he really has, then i think we will be closing the thread.

and 871LEIroc,
thats why we have so many different boards. it would be different if you said, i did this mod this weekend and then ran this time..... vs...... my old time......etc..

NO PABLO BZZZ YOUR WRONG, NO ONE ELSE HAS TOUCHED THIS CAR I BOUGHT IT FROM A 3RD GEN COLLECTOR IT WAS 100% STOCK. MY CAR RAN A 15.896 DEAD STOCK. WITH THESE MODS IT DOES RUN 14'S
ENGINE:STOCK HEADS,VALVES,& CAM
EXHAUST:STOCK MANIFOLDS,DUAL 2 1/4 INTO SINGLE 2 1/2 Y-PIPE, 2 1/2 INTERMIDIATE WITH FLOWMASTER AND DUAL 2 1/2 OUTLETS
IGNITION: MSD CAP,ROTOR,COIL&WIRES,BOSCH +4 PLUGS
AIR INTAKE:5.0 H.O. DUAL SNORKEL,K&N
OTHERS:HYPERTECH PULLIES,LOW TEMP FAN SWITCH,180 T-STAT

SAY WHAT YOU WILL I DON'T CARE IT WON'T SLOW MY CAR DOWN ,IT'S GREAT WERE ALL ON THE SAME SIDE HERE. USUALLY PEOPLE ARE HAPPY TO SEE COOL CARS BUT IT MUST BE DIFFERENT HERE.

<font face="Verdana, Arial" size="2">ENGINE:STOCK HEADS,VALVES,& CAM</font>
Ok, then how did you dump a whole 1 1/2 seconds of your ET without changing the heads (most restrictive part), cam (econo-gasser), and not do any head/valve work. See it just doesn't make any sense. See, I changed everything but the heads (which I built instead, dumb move). I put in a new cam, and intake, and exhaust.

Just so you guys know, those mods listed are the ones that took most of the time off my ET. The exhaust/ignition did nothing! So, I didn't list all my mods. I felt the list of every single mod would be too extensive for each post.

<font face="Verdana, Arial" size="2">EXHAUST:STOCK MANIFOLDS,DUAL 2 1/4 INTO SINGLE 2 1/2 Y-PIPE, 2 1/2 INTERMIDIATE WITH FLOWMASTER AND DUAL 2 1/2 OUTLETS</font>
Ok, Stock Exhaust Manifolds are also what really restricts that motor's fullest potential. Why is it when I had a custom 3" inch exhaust (with headers) installed, it only took .2 off my quarter mile time? What's your secret? It seems as though your almost-stock exhaust is the ticket to cutting most of the time off your ET. Wow, Dual 2 1/2 inch outlets? How much did that chop off?

<font face="Verdana, Arial" size="2">IGNITION: MSD CAP,ROTOR,COIL&WIRES,BOSCH +4 PLUGS</font>
I hope you know, that basically did nothing for your stock motor. It didn't even do anything for my non-stock motor. Nothing. I had a whole new ignition put in, including new distributor, cap, coil, ignition box, wires, and plugs....but it took a whole .02 seconds off my ET. Again what's your secret?

<font face="Verdana, Arial" size="2">AIR INTAKE:5.0 H.O. DUAL SNORKEL,K&N</font>
Ok, that is a very basic mod that has a decent gain, but no second off an ET. I did the OE, and then the Dual-Snorkle and it gained me probably 10-12 horsepower and barely anything off the ET. Again, did K&N make a new filter I haven't heard of, so what's your secret?

<font face="Verdana, Arial" size="2">OTHERS:HYPERTECH PULLIES,LOW TEMP FAN SWITCH,180 T-STAT</font>
Ok, pullies are good, but not too much of a gain. Low temp fan switch, heck why didn't you just go with a on-off fan-switch like me, so it's running all the time? It probably gained me barely any power. 180 T-stat, ok but no major gains there. All in all, where is the thing that got you into the 14s? None of those add up to a 14 second 1/4. You say you ran a 15.86? You could be running a 15.6 now at the best with the mods you listed. But then again you could have done more harm than good. See you need to finish the job. The other stuff you listed doesn't do anything unless you have other mods that are dependant on them.

CAN YOU STOP TYPING IN CAPS?

Well your '91 Formula TBI times might be nice , but they are nothing compared to my '92, RSS, TBI 350, 5-speed, T-tops and 3.88 gears. They made those stock too you know. Check this chart. They are listed right under the '91/'92 Formula TBI. https://www.thirdgen.org/newdesign/tech2/techdb.shtml With just SLP headers and 3.5" dual outlet exaust I droped the times down to 13.00 flat from a 14.99 time stock. Really. Its true, its true. People are happy to see cool cars but it must be different here because I get called a lair. Lisa's Dancing makes my feet sad

You still aren't getting this are you? 14s with an L03 take mucho buxx and mucho time. You aren't going to run 14s with a completely stock motor/drivetrain.


I doubt snflupigus would want to go see your car whip out a 15.6. It wouldn't impress him any. Unless you tell every single mod you did, you WON'T get any respect from us.

You just want this post closed because you know that we caught you in a big lie.

Gentlemen,

I also have a 91 Formula WS6 which came stock with the 170 hp TBI 5.0. Not many were made that way, since the ws6 is insulted by that pitiful engine; but it was the stock Formula engine in 91-92. With the mods he has, the engine should make about 200 hp.

However, I'm thinking the gears are 3.73's.

Dude, are you sure the gears aren't aftermarket 3.73's??

PhantomChamp you are my hero, yes 1991 formulas came with tbi engines. My gears are 3.08 i made sure that they were when i put my zexel-torsen in. You sound like an original f-body guy, around here when someones car is fast you cheer them on not boo them. i usually don't let people on the net get to me but this is bull. By posting these times i hoped to only compare not to say haaa i'm faster. I figured my times were normal for a 5-speed tbi's with small mods. anyway all of my mods are listed ws6formula and besides whats so special about your mods?
you seem to run 14's with nothing special either. Tas how do i post pictures on this site? I want you to all see what your yellin at.

Did you happen to notice that I said I hadn't listed all of my mods either. I said I only list the ones that made the BIGGEST gains. Those aren't all my mods, but my mods are way more believable than yours.

But running 14s with your mods is impossible, unless you are about 2700 lbs with you in the car. I still don't believe the times you ran.

we have had the whole conversation about how much modding it takes to run 14's with these cars, and the result was really not too much. it would however take more than you seem to have. unless the car is some sort of mega light freak or has had some thing done to it that you were not told about when you bought the car, i doubt it can happen on your mods.
could you please post the entire time slips, with all the increments. 60', 330', 660' and mph, 1000', and 1/4 w/mph.

Also post pics of the hidden N2O system.

I also question the track you went to and their timing equipment. A local track here by Detroit has a screwed up timing system, so its not that uncommon.

Lets see the timeslips. Don't forget to include pics of the car with the number on the window so we can match it to the timeslips. Heck, anyone can borrow my 14.0 timeslips and say their TBI car went 14.0

Hey this isn't The fast and the furious, I hate n.o.s. more than i hate rice burners. It is at least nice to have some people on here who can say something decent. Like I said before there are no hidden mods. The track I go to is an NHRA track but on street nights they run there + or - .05 equiptment
which means there could be a .05 difference. I didn't post my time to rub it in I thought that's what they would all run, my God LO3's aren't that bad. Heck people on the V-6 board run 15's. Does anyone else have #'s for a similarly equipped LO3?

cody, email me. I'll go to scrib with ya. I would also like to check out your car, and hang with a fellow thirdgenner sometime. as well, if you have an l03, i would like to see if the chip ive burned for my stock l03, will make a difference for the better on your car. Just email me.

The reason nobody beleives you is because nobody has seen it before, its just how things are, see to beleive, would you beleive me if i said my stock l03 runs 13's. no.

Tas,

I know I haven't posted for awhile, but me and Cody are not the same person.

Cody,

I've never run 14's in mine, though it is an automatic. I really believe I'll be able to once I get 3.73 gears, though. I have basically the same mods you have.

For the rest of you,

I got my car stock and then added a hyperchip, high flow exhaust and improved cold air intake which really did make a difference in horsepower and throttle response. That and I use an Octane booster with premium fuel.



Now y'all don't fight anymore!

Hey if you have so much fun at your other board stay there you worthless piece of s**t, people like you who have no car worth talking about just love starting up a flame again but do it somewhere else. And I suppose being the cool guy you are you'll have to carry this on for another 20 topics but I don't care, if you have that much time on your hands good for you.

I hope you realize there are tons of other people that like to post at NEThirdgen.org, mainly because of it's excellent non-tech board. So he is welcome here just as much as you are.

14.5 is way too good for the mods your car has. My mods aren't really for the street, I have no backseats, or sound deadening material. I would never list all of my mods! That would be WAAAAYYYY too long of a list, and Brad (administrator) would probably ban me for having a page long mod list. Besides that I'm too lazy to do that. So I listed the mods that lost me the most time off my ET.
