Gotta a few kills in my RS last week, both close.

First one was just stoplight to stoplight against a V6 Tiburon with an auto or someone afraid to stall. Didn't stall my 700, just punched it. Got by him, but barely. If he would have had a 5 speed I am quite certain I would have lost. These things are surprisingly quick. My 255 lb ft. versus his 181 saved the day!

Second one was a friend with a 4 cyl Tiburon 5 speed, who refused to believe I took a 6 cyl. We ran a full quarter out on a rural highway twice, and it was way closer than I thought it would be, but with a 5 speed, 2900 lbs, FWD, and 138 hp, I shouldn't be surprised.

His is a 2006, stock except for Goodyear directional tires.

The first raced I stalled up the 700 (stock stall converter) and didn't hook at all, and lost by about a half car. I was fairly shocked and asked for a second shot, to try a stall-less launch.

Second race I didn't stall it at all, just punched it, and hooked decently and won by about the same margin that I lost (half car). He still got me off the line, and I was almost to 3rd gear before I had reeled him in. But the first race he absolutely destroyed me off the line.

He was stalling the hell out of his car, and that thing hooked both times pretty well, as well as powershifting.

These cars are quicker than I thought! If I had a posi and good tires, I would have put 1 or 2 cars on him pretty easily, and if he had an auto he would lose badly. An RS with the 5 speed and 3.08 posi should be fine.

Any TPI or even L69 car shouldn't have a problem with one of these things, but for any fellow 700-R4/L03ers, don't think you can walk one so easily. And if you've got a 60 degree V6 or Iron Duke, don't even think about it, lol.

a posi would absolutlely help with your launch,3:42's(I'm alittle biased).What have you done to the car so far?are you bone stock?

80smetalfan

Advanced base timing, PROM tuning, straightpipes (no cat or muffler), 160* stat, and open element. Stock, otherwise. Best time of 15.7 last summer. Can't even hook at the track with this one wheel wonder!

Put in a 180* thermo. 160* is too cold.

Thats what I was thinking

80smetalfan

They both challenged, and I judged them as being fair game for the measly RS. Nothing wrong with a little fun.

hehe. might as well race what's in your league :P. there's nothing wrong with having a little fun. after all what's a thirdgen for?

So, lo3 is the 305 tbi? If so, my buddy did something to his and is almost dead even with a tpi 305.....lol. My s10 currently pwns them both though.

89IrocZ350TPI

Its kind of tough which "league" to put an L03 in isnt it? I mean if you put it up aganist a 5.0 GT say good night.

80smetalfan

Well if this TPI 305 is an auto and is a little out of tune, this is entirely possible. My RS hit 15.7s, which is within the range of a poorly maintained auto 305 TPI. The autos only make 195 hp, which is only 25 more than the 305 TBI.

2-toneTA

if it matters, it is a 92 RS, vs a 87 Iroc-z. My friend's rs has a 5.7L throttle body, and exhaust. The iroc only has exhaust.
edit: sorry for hijacking the post.....there really isn't a point to make a new thread

80smetalfan

I don't care, lol. This thread wasn't really interesting to begin with.

2-toneTA

crap, my friend's rs is a 305 with the throttle body and injectors off a 5.7L truck. Thought I'd clarify that....I hate overwrite. But this kid always thinks his 87 iroc is fast.....I stuck with him, and passed him with a 98 s10.......lol No idea on track times for the iroc or the rs, but my s10 usually beats them both by 2-3 car lengths n/a. I usually run mid to low 15's n/a, and did run mid 13's on spray(college bills cought up with me, so I had to sell...) I wish I would have been able to keep it for the TA.

89IrocZ350TPI

L03's are slooooow

90CamaroTBI

Not always bud.

89IrocZ350TPI

Ya i know. Just wanted to get some angry responses.
There not bad if you get that peanut lg4 cam outta there. Then get a cat-back with free flowing headers, then go with a better intake manifold. Modify the tbi, and some free mods and you will be moving.

My old car was an lg4...then I gave it some steroids and it became an L69

TA4life

i wouldnt laugh at tiburons...there are a few fast ones out there. i have one and i am thinking of getting a turbo. ngm is making a kit to put out 390hp on pump gas so tibbys arent to laughed at...unless stock of course

stu

There was that old body style that ran tens on Walmart tires. Of course it had two turbo motors and synchornized auto trannies.

TA4life

always one to pop off dumb comments like that when u clearly have no idea huh

stu

Apparently you are the one with no idea.

Here are some pictures of the burn outs clown:



Now what was it you were saying?


P.S. Man do I get sick of the retard kids on here.

ALWAYS! Ive never heard of an L03 running any better than 14's. Thats a dog to me.

There are some that run faster than that...just few and far between.

lol i have yet to see an L03 locally that even runs a 14

84L69TA

All the ones I have seen have a hard enough time breaking into the 15's. LOL

89IrocZ350TPI

Ya LO3 cars start out with a poor building block. Peanut cam, restrictive heads, stuffed up exhaust/Intake. 170 hp stock for a 3400 lb car is only good for 15.9-16.2. So it takes alot to drop two seconds.

ShiftyCapone

iTrader: (7)

The reason why you don't see fast Lo3's is because people for years have thrown miss matched parts combined with hearsay theories as to why TBI sucks. They don't do the chip work and supply the motor with the necessary fuel. They get fed up and switch to carb. There are more and more people who are taking the time to learn the system and are having great results. I too will be in that category (TBI head project .) Dewey316 ran a 14.5 with headers, 3.42 gears, untouched heads, and tuning. Thats it. He then added a cam and re-tuned to run a 13.9. He only did that because he learned how to do the chip work. Fast355 has a 312 TBI in a 5700lb van that runs 15.5's!!!! In a lighter f-body that would be low to mid 13's with ease. Both examples had the so called "worthless" TBI heads. TBI is not as bad as people claim. LO3's were slow beacuse of their crappy cam, exhaust, and tune. Not because it was TBI with swirl port heads.

90CamaroTBI

Thanks for showing us support Shifty.

89IrocZ350TPI

btw I was not trying to put down LO3 cars. Yes you can build up the engines and make them fast.

I have a question would it be cheaper to just go out and get a 350?. Or would it be cheaper to build up an L03? If you were shooting for lets say low 13's?

ShiftyCapone

iTrader: (7)

You have more potential with more cubes. You can get a roller 350 for next to nothing which is a great start. Fast355 also has a few worked 350 TBI's and he makes roughly 340hp and 450ft lbs with one of them. However, any TBI motor will require lots of tuning and key parts selection.

89IrocZ350TPI

Ya, thats what i was thinking. I guess you can have a fast l03 street car with the right combo's. For the strip you may want to upgrade to something with more potential.

ShiftyCapone

iTrader: (7)

Yes you can . I hope to have one of the faster LO3 cars come this summer. Hint hint.

89IrocZ350TPI

Get into the 13's and that will be the fastest one ive ever seen. I did see an lg4 run in the high 13's before. Pretty much the same thing though.

ShiftyCapone

iTrader: (7)

If I only go 13's I did something wrong . Dewey hit 13.9 with simple mods. Thanks to guys like him, kdrolt and fast355 I can take their lead and run with it I won't go into much detail though. You guys will have to wait.

89IrocZ350TPI

So are we talking all motor or a little bit of spray? 12's or better on an l03 would be insane!

ShiftyCapone

iTrader: (7)

All motor. Dewey already went 12.8 with his LO3 on spray.

He had a small cam and unported heads. You can see where I am going with this.

89IrocZ350TPI

Yes I can. Your going to have an all out L03 pretty much.

ShiftyCapone

iTrader: (7)

You got it.

Lots of fuel
Tuning
HUGE cam
ported heads (with lots of work)
= fast

(This sounds like every other SBC build doesn't it...I guess the LO3 was no different)


I want to end all hearsay with the LO3 by summers end.

89IrocZ350TPI

Id love to see the look on the face of the LS1 owner as a third gen flashes by.

brodyscamaro

Let's run.

stu

Good luck, people have been running 10's in street driven imports for years now, and the scene still sucks.

ShiftyCapone

iTrader: (7)

Very very true. I think there are more 10 second imports than there are 12 second LO3's. None the less I want to change some of the minds here on TGO.

urbanhunter44

iTrader: (3)

of course its possible to do it with an L03, but for all the effort put into it you could be running faster with a different motor.

89IrocZ350TPI

That would be my choice as well. Ive never really seen a 10 second L98 car. Most people upgrade to an LS1 or a crate motor.

89IrocZ350TPI

I think he is mostly trying to prove a point though. Everyone should agree that a stock l03 is slow,but it has potential like the lg4 to be made fast. Their is a good website out there about the l03 engine and how to build it. I think its called "modifying the L03" or something like that. Pretty good read.

ShiftyCapone

iTrader: (7)

True, but that is not the point of doing this. The point is to learn every single parameter of an IC engine in relation to parts selection and power potential. Sticking with a TBI motor forces you to do this more than most other combos (cough, LT1, LS1). It is not as easy. You can do it with minimal funds as well. Most of the parts you use can be used on a larger motor should you decide to ditch the LO3. None the funds will go into the bottom end or the heads.
