i know a bone stock 88 trans with 350 went 14.30's in the quarter, but the 60ft was only 2.1 could have done a little better with better tires

14.30 from an 88 Trans Am?? Damn thats fast! I have a Hot Rod mag from 1988 that lists an 88 L98 as 15.0.

I ran 14.1 stock with same gears on an 88 iroc with only 18k miles so yours should be just as good. nice car

I really really doubt it would go faster than 14.6. Those cars are heavy with power seats and such. All I know is I have never seen one run faster than 14.8 and that my car at only 14 flat makes them look silly.

87iroczmd

i read an article that listed an 87 as 14.3 and another that had an 87 that turned a 14.5, 88 should be the same, but i also know what i have seen at the track, consistent 14.3's and 14.4's from my friends 88 trans stock, 2.1 60ft, some cars are running bad and no one realises it i guess, i know my car sometimes feels normal even though it is a second or 2 slower than usual, it is hard to tell when it is working and it isn't

Magazine references are good for one thing... to prove what that individual car is capable of in that drivers hands. Not all cars are treated the same over the years and they all don't come from the factory on an even level from the start either. My father had a 64 gto and his buddy had one too. both were new and one was a hell of alot faster than the other no matter who drove it. These are called "ringers". Run it and see what you get. gtechs are good for time within +-.1 if you spin them in first get new tires. with the tires made today there is no excuse for a stock l98 to spin em. people pay thousands for a car to be fast and then put $150 tires on the rear. I bought BFG kdw's and I couldn't spin em if I wanted to. Every 0 to 60 was identical within a few hundredths. get good tires.. a good tune up and with the low miles you should run good no matter if you have a ringer or not. good luck

My 88 Formula went 14.30s at 95&96 MPH bone stock. That was with 2.0-2.1 60ft times. T/As are a little heavier, but I have seen them run similar times.

Just to let you know, I put some headers on it and it dropped me to a 14.10 at 98-99 MPH.

Ported plenum, added an AFPR, TB coolant bypass, etc and it will do 13.90s with a 13.86 @ 100MPH being the best.

Yeah, I dont know what the deal is about the mustangs just dominating Fbodies in the late 80s.

Ill take that back...I do know. The main reason is the 305TBI. (Flame suit on)
A 5.0 mustang is a 5.0 mustang. But a V8 F body could have had 1 of many engines in it. CFI 5.0, L69HO, TBI 305, TPI305, TPI350, etc.

Now, what are the chances that a guy in a 5.0 will race an Fbody that has the engine that will actually compete. Not gonna happen all the time. The L98 should win, the 5 Speed TPI305 cars have a GOOD chance and the L69 HOs would win in the early 80s.

Bottom line...A L98 equipped Fbody (MAF or SD) sould be able to take a stock Mustang given that both are stock. I have never been beat by a STOCK mustang. Been beat by modded ones though.

I don't know what you guys are talking about with stock 87's and 88's going 14.3 or ever 14.1. That's nuts in my opinion. The best I ever got my stock 87 GTA to run was around 14.8. According to sports car international they did some runs on two cars. An 88 Formula and a 91 GTA SLP. The formula ran 15.0 and the SLP ran 14.60 and that had 290hp. They said that with better traction they might have been able to hit 14.30. It seems hard to believe that a car that only had 230hp and weighs 3400lbs could go 14.30. Take a look at the new Honda S2000. A 240hp car that only weighs 2800, revs to 9000 and peak hp is at 8300, but this car only runs 14.2 at like 99. To my knowledge and to the best of my ability running an 87 GTA and an 88 IROC I never managed any better that about 14.8, but if some of you did, great for you.

Not all car are the same, I've seen some stock third-gens runnig low 14s. Just look at the LS1 cars some pull a mid 13 @ 102 and some a 12.8 @109. Thats a big difference. Weight veries between them too, some are 3320lbs without power options, some almost 3600lbs. Then there is weather elevaton, track conditions, gearing and driver. My B4C is 3290lbs with a glass hood and welds, not many third-gens are.

"It seems hard to believe that a car that only had 230hp and weighs 3400lbs could go 14.30."


No, its not hard to believe. Ive seen it too many times. Ive seen Irocs do it, GTAs, Formulas, etc. Now, Ill admit that not all of them run this fast bone stock. I was honestly expecting 14.70s the first time I took my formula to the track. I was happy though when it was running 14.30s all day long. I know Im not the only one that has seen L98 cars go low 14s stock. I heard a guy on Camaroz28.com say that he ran 13.90s stock in a SD L98 car.

the reason why thirdgens don't get the respect is because of the HP rating. People don't understand what hp is. Torque is what matters. HP is just the ability to have torque at higher rpms. hp = Tq@rpm * (rpm/5250)All tpi's, especially the l98 have a great torque curve.. they just lack a little up top. Like said before very few irocs had the hot setup too. There is no reason for anyone to lie about their times. No manufacturing process could ever be repeatable and consistant enough to generate identical cars. If someone doubts another guys car can't be over half a second faster just because its the same make and model and year then i'm sorry.

88 Trans Am L98 coupe 3.27 1/4mile 14.6@95mph

Thats about what a stock strong running one should run,I've seen anywhere in tests from 14.2 for an 87 (HPP and was a ringer)to 16.0 from Moter Trend(105+heat,and was just a dog)I ran 14.3@96 with my 90,which is right on what a 90-92 dual cat F-body should have ran stock(14.2-14.5,95-97mph)take away about 3 tenths and add 2mph for the dual cats and speed density,and that gives you the 14.6.

Little GTA

At 160K miles...stock...but with rebuilt trans (nothing special) and good tune up before going to track:

14.1-14.3s at 96-98mph (Hey...I'll take it. No mustang losses)

Don't believe it...well, that was with 2.1x 60 ft times on Dunlop tires. I don't even think they are high speed rated or anything.

Maybe the good times were due to cool temperatures or something. All I know is it would pull real good off the line.

Well, GM High Tech did a story on just that - a 1988 GTA. It was pretty hefty w/ the 200lb driver. I belive it ran a mid 14.6 w/ 60,000 miles all stock. But, as we all should know by now - some cars are just ringers from the factory. My mother's Grand Nat is a prime example. It has: K&N cone filter, gutted cat., street chip, adj FPR, and plug wires. Went 13.20's on worn out drag radials. There were several cars at the track that night with a lot more than we have and they were either rnning 13.30's or 12.80's depending on the size of thier turbo. But, I'm not bragging, just noting that some cars run better than others.

I think one of the main reasons we don't get any credit is becuz of all the dam 305 TBI's that ran around in the day.(no offense to TBI guys) Face it, there are too many of them, and all the Mustang's had their big "5.0" on the fenders. All fast stangs were 5.0L's and not all 3rd gen's were 350TPI's or 305TPI/5speeds. I think our cars just got a bad rap becuz of all the slow TBI's on the street. They are NOT slow. They WOULD/WILL run with 5.0's. Stock vs. Stock or Built vs. Built. Thats IMHO, and I've seen it a lot. Hell, my GTA isn't even the strong running G92 with 3.42's... its just a 3.08/T5 with the 305 TPI. You tell anyone you run a 305 and they laugh... why? becuz they think of 305 TBI's! haha Let them think that, we all know how strong TPI's are and I've surpised many people with my little 305. They'll have a hell a laugh when I get the 350 mated to my now 6-speed GTA and I tell them its a 305/T5 and kick their *** hopefully running low 13's. "Its just a stock 305/5-speed" I'll say! lol


*BTW- I have a buddy in my local car club with a bone stock '88 Formula 350/auto and ran 14.8's... 1st time on a track. He put some cheap Flo-tech headers and a tuneup and ran 14 flat! I think thats pretty darn good.

The L98 or LB9/5-Speed combo's are in the minority.

I've been shopping for a 3rd gen lately and most of the Formula's I see are the 305 TBI and the IROC or TA's are the 305TPI Automatic.

It's really luck of the draw. I think there is up to a 1 second difference between different cars. My '87 IROC w/ no mods ran a 15.1 & 93mph, but w/ a lousy 60ft. time. With some traction it would have run 14.7 or so stock.

A friend of mine had a red 93Z 6spd that ran, BONE STOCK, 13.1-13.3 all day long. It left so hard one time it tweaked the unibody and he couldn't close the door! I $hit you not...somtimes you just get a "good" one.

My '87 L98 was only able to pull 14.81@91.64 on a 2.09 60' when stock. This was at 44K miles on a 105 degree day. I have to wonder about anyone claiming their "bone stock" L98 ran better than 14.5. Maybe the dual cat cars like Z_Ghost, but not the single cat early L98's like mine.

Look at the temperature that you ran at though - 105*! That's hot. When I ran my 14.3 it was like mid 60's. That alone is probably enough to account for the difference between the two. Remember, unless times are on the same track on the same night - conditions are probably nowhere near equal.
