i guess it had slicks then.lol. They never made an L98 car that ran 14.2. Are you saying that was a professional driver too?

 

maybe it was a Firehawk?

 

.....?

 

bolt-ons will get you that if said bolt on is a supercharger! You know what that sounds like a good idea I think I oughta try that. Supercharge it, work the engine with bigger injectors and actual headers and make sure it wont blow when you run it, cam, roller rockers, build up the tranny, and put on some better gears say 3:73s. That will get you one fast third gen but take a good size chunk out of your wallet maybe 5k-6k+. But you will be getting some real nice track times! Imagine if that 350 was exchanged for a 1k+ 383 stroker motor and a 6 speed! You could start smoking some GT500s at that point! Heck you might be able to beat some GT500s with just a built up 350 with a procharger or top of engine supercharger with gearing and built trans with shift kit.

 

honestly, to run low 13's in an fbody, you will need 300 hp or more

 

ha, 373's and a supercharger! really. That wouldn't work out too well.

 

how about leaving your gears alone(because you are using boost) and how about using low boost,maybe 4-6 lbs and spending under a grand on a turbo kit and turbo header?

 

i would rather use a 323 gear ratio w/ a supercharger.

 

Most definately, 1.6 rockers and sticky tires added to the previously stated boltons was the trick for me. Stick cars blister tires. My buddys car was the auto car.
Depending on your altitude and DA a full bolt on L98 w/ a stick will run bottm 13s at sea level. real tires and 5000 rpm launches will get a decent to great driver in the 12s been done many years ago all N/A

 

My buddy and I were one of those that ran 14.1-14.2 stock! Pulley kit and
k&n filters air box cut out and ramair pans made 13.8-13.9 then I added a 5spd I was always 4-5 tenths faster than my buddy.. gotta love Houston Raceway Park 1988-1994 best traction ever!
Hell when the Lt1s came out they were running mid 13s
Ls1s run easy 12s at sea level seen that too many times
I also miss having an overly underestimated L98

 

I dont like the idea of putting a turbo on a Camaro, especially a V8. Superchargers in my mind sound better and feel smoother.

 

my buddy has a 02 Mustang GT 5 speed and i have a 89 GTA. just minor mods to mine and his all stock. we did a roll from 60 to which i began to inch ahead of him until about 100+ we both started in 3rd gear.

 

Awesome job especially with a heavy GTA

 

Lt1's never ran in the 13's either.They are low to mid 14 sec cars

 

that is because it never happened.

 

same goes for a supercharger. you only need 4 lbs of boost and then you will beat c5 vettes and Ls1's.

 

At the flywheel, yes most likely. To the wheels, def not.

Why not? My brother had 3.73 on his Roush supercharged 07 GT and it was a rocket. Now on a turbo car lower gears are better because you want the boost to do the work, but superchargers like a little gear too.

Average driver low 14.......good driver, good tires, high 13.

I really hope you were joking on this statement!

 

Go ahead and try out 373's on a supercharged f-body.lol

turbo car's lower gears? you mean higher gears ,and if i recall a supercharger is providing boost too.

 

and you don't need a lot of boost with an 8 cyl, we are not dealing with a little 4cyl here.

 

[QUOTE=ninetyone;4827377]you want the boost to do the work anyway.Before the days of "affordable" fuel computers and tuning,you had to sacrifice your timing for boost. It was one or the other. I always chose boost.

 

How would that be any different than on a V8 mustang? My brother's mustang made way more power than a bolt on L98 before the blower...

Yes thats what I meant, and while a supercharger provides boost, it is completely reliant on the belt meaning the faster you bring the motor to higher RPM, the faster you come into boost. With a turbo car you are making boost based on engine load through the exhaust, so you actually want to make the engine work longer to keep the turbo in full spool as long as possible.

4 PSI on a V8 is just as useless as 4 PSI on a 4cyl. I honestly don;t even know if there are any supercharger kits that are that low out of the box.

Instead of making post after post, you need to multi-quote....that way your not putting 20 posts up for every one that someone else does.

 

why would i make that up?

 

Dude you are so far out of knowledge its rediculous, maybe where you live the weather provides terrible racing days. At sea level these times are 100% accurate. I suppose you never saw the 02 as that ran 12.69 on tires,untouched from the dealership at ATCO RACEWAY go to youtube type in stock ls1runs 12.69 @ 110mph.
You can doubt it all you want but it has happened many times. Lt1s are slow what does your car run?

 

My bolt on Lt16spd runs 13.3 on 19s with radials 12.8/9 with DRs at 3000' yeah I guess Lt1s are slow......
Gone 11.3 on 150 shot

 

This particular car was a 91 Z28 fully optioned on 18" IROC rims with plain old street tires. Yes I saw the timeslip too. And just because you have never seen it doesn't mean it isn't true. What are you, like 15? I have never heard so many ignorant, ill-informed, dumba$$ statements from one person. Just about everything you say is false in some way or another. You should really do your homework before you post anything else. You won't look like such a fool.

 

i feel like i'm on LS1tech

 

I guess you want sound over going fast. A company called On 3 Performance makes a single 70MM turbo kit for my Mustang that'll make 440 RWHP @ only 10 PSI on stock internals, stock cams, stock non ported heads, everything bone stock. That's over 500 HP at the crank, pretty much doubling the stock power. I'd take a power adder that doesn't sound better, or feel smoother, with results like that any day.

It probably did. I was only getting 2 lengths, 3 or 4 lengths tops on the one run against you, and my Mustang has some minor stuff done to it. The other one mentioned was stock.

 

Hey ninetyone
What does your bird run?

 

This thread needs videos

 

I could always get my friend to record if ninetyone wants to meet up again, just for the sake of having a video.

 

my buddy has a video on his phone of my gta vs the 02 GT.i could get that from him pry.

 

I'll get an exhaust video of the Mustang tonight if my friend feels like recording.

 

i have no idea man, never timed it.

 

you show me an actual document from a known,qualified source like motortrend or car and driver and i will believe you.

 

hey whitedevilTA, don't you know that with boost, and especially higher boost pressures that traction becomes a major issue? On a friends Formula ( supercharged 305) he actually ran slower at the track with 373's than with his stock (1LE optioned) 342 gear. On the street with 4 lbs of boost ,the car would embarass LS1's and c5 vettes.

 

As a matter of fact, go talk to some of the twin turbo Supra and 300zx owners out there, I have seen some stage 2 guys actually run almost a second quicker than stage 4 due to traction issues.

 

your Lt1 may run in the 13's indeed, and you also have 373 gears it looks like, but they did not run 13's from the factory.They were a low to mid 14 sec car.

 

and i don't know what my car runs,but i can definately hang with a stock Lt1.

 

Well I can assure you I have seen many lt1s run 13s all day at sea level. Try not to go by what motor trend says the don't have drivers in those cars!
As far as me having 3.73s its not much more than my stock 3.42s ..... 16" wheels 3.42 19" wheels 3.73 you see the compromise here......... I am also 4-6 tenths slower up here vs sea level. Long before my headers,exhaust,rockers and tune I ran 13.9 @101 on 18" goodyear F1s
I am not trying to be a dick but your facts are a bit off

 

my 88 IROC is stock except ZZ4 heads and I beat my buddy in a 2001 GT with just a cat back....we ran 4 times and 3 out of the 4 I pulled him bad the 4th time he took off before me

 

Thats what those cars can run STOCK!

My 5,600 lbs 1983 G20 van with a 081 head 305, production LT4 cam w/1.6:1 rockers, stock TPI intake & runners, Doug Throley Tri-Y headers, dual exhaust, and repgrommed DIY chip ran 15.01 @ 92 and it had 3.08 gears and a 1,600 rpm converter in the 4L60E That really makes my van a bolt-on LB9 carrying an extra 1,700 lbs and pushing horrible aerodynamics.





The transmission was essentially dead in this video clip, wouldn't even make a WOT 1-2 upshift without bouncing off the 6,000 rpm rev-limiter from slippage. 2-3 was way early too, because I had messed with the shift points trying to get a clean 1-2 shift not realizing how badly the clutches were slipping.

Here's something entertaining, since someone wanted videos, a quicky fly by of the Mustang taken earlier tonight. It was through 3rd gear, and I hit 4th right as I passed the camera. One would almost think it's an automatic, I shift too quick.

http://s685.photobucket.com/albums/v...stangFlyBy.mp4

Quick rev.

http://s685.photobucket.com/albums/v...MustangRev.mp4

I wish the IROC was running.

 

HAHA, I know the feeling of taking people by suprise.

I actually drive to and from the track like this and have even driven it to work on a Saturday after racing Friday night. Its pretty funny when people that don't have a clue run their mouth about what something can and can't do and are quickly educated. I had a 5.7 GTO find out the hard way a few weeks ago that he couldn't touch me to 60 mph.

Wait a minute, what did I say that had to do with taking anyone by surprise? You confused me.

 

I got off on a tangent with you talking about your shifting.

 

Ah, that's it. I just have a lot of practice.

 

The L98 is a seriously underated engine honestly. With bolt-ons they will FLY.

It's being underrated by 3 tenths of a second in this case. 1991 L98 Corvette is rated at 13.9 seconds.

5.3 = 0-60

13.9 = 1/4 mile

http://www.exoticcarsite.com/0-60-qu...mile-times.htm

 

Need to spend some more time on these boards then.

My L98 with just 2800 stall and hooker 2055 shorty headers, gutted MAF, gutted TPI air box, and flowmaster 80 series 3" catback on street tires and 2.77's went 13.89 at 96.xx mph. 1.89 and 1.88 60 foots. Many 13.9-14.0 passes.

Then i added ET streets and 3.42 gears, it went 13.63 at 97 in good air with a 1.7x 60 foot. I'd have to look it up again. Search for my posts in the drag racing forum.

Then I added stealth ram intake, 1.6 rockers, underdrive pulleys, custom tune, lightweight weld racing wheels, and in cold november winter air (40's deg) it went 12.99 and 12.95 at 103.8 mph on 1.71 60 foots.

If your bolt on L98 doesnt go mid 13's in decent air conditions, something is very wrong

My friends 88 formula went 13.59 at 99.x mph in dead of summer in 80's deg heat with just SLP runners, bigmouth base, 3.73 gears, full exhaust mods on street tires with 1.93 60 foots. Converter and slicks and he would be low low 13's with TPI mods
