I just got done building my 1991 Camaro RS up. It's a built TBI 350 with:

Ported Vortec Heads

LT4 Hot Cam

Air Gap Intake

Comp 1.5 Full Roller Rockers

Elgin Roller Lifters

Lt4 Valve Springs

Shorty Headers and Y Pipe going to 3inch Exhaust, No Cat

MSD Plug Wires, JEGS Distributor, Summit Hot Coil

454 Throttle Body

Soon to be a 3.08 posi, BTW it's a 5 spd

I'm a senior in high school, and like to race with the classmates

Here's my competion:

Late 90s Honda Prelude.... Stereotypical decked out rice burner.. No turbo though

2006 Grand Prix GT.. Stock

2008 Pontiac GXP.. Exhaust Done

2008 Infiniti G37S... Stock

2005 V6 Mustang.. Stock

2006 Pontiac G6... Stock

And finally.. An 89 pontiac firebird.. I think it's an LB9 car

Think I can take them? Which ones would I have problems with? The Infiniti kind of worries me...

 

Yea id say the infinity would be the only one to give you trouble. Your engine should be pretty strong . Good luck knocking off those imports.

 

I have a similar combo.

SBC 350
AFR 180cc heads
LT4 Hot Cam with 1.6 roller rockers
Weiand Speed Warrior intake (Basically a Performer RPM clone)
SBC TBI bored to 2.00 inches
T5 transmission
3.73 Auburn type posi rear


I went 13.7 @ 105MPH with a 2.3 60 foot on street rubber. I don't think any of those cars could keep up.

 

Thanks man. It's sad. I feel like I'm the only one who likes muscle cars in the school. Everybody into this tuner crap.."

 

I don't know about that.. Look up specs for that infinity

 

Think you could run low 13s?

 

No substitute for the sound of a well tuned V8. My car isnt fast by any means but damn it sounds and runs good. My wifes v6 altima is fairly fast in comparison to a stock third gen but id much rather ride in my firebird. And we must not forget these cars are 20+ yrs old and fast for thir time especially against the import cars of their time

 

Senior in high school and have friends running/driving those cars???? I could only have WISHED that in 1980!!!!!! Good Luck! Show'm whose boss!

 

Im pretty sure with a posi-rear you should run some low13s. Id think hard on maybe some 373 gears also

 

It's funny because I'm the only kid who pays for parts, gas, and insurance. I also do all the w

 

I also do all the work to my car myself. I don't think I did too bad for a
17 year old.

 

Well...... If their mommy and daddy can afford to give jr these *cough caugh* cars, They can afford 100 bux a pop for you to mop up the road with em.....

 

No.. Me and my dad got in argument about that. He says it wouldn't be worth the time or gas to switch to 3.73s. He says I would barely feel the difference. Only in drag racing would it make a huge impact impact. I drive this car a lot. So it wouldn't hurt to keep in the 3.08s.

 

What kind of horsepower do you think I have?

 

He's right.

but,

That's kind of the point though, with the 5-speed you can run gears like 3.73's and it still be streetable.

 

That's what I told him.. Buts he's the mechanic and I'm going to listen. I wanted to go with 3.42s. But why not just stick to 3.08s.. It cruises down the highway PERFECTLY. And I still have extra ponies for the high gearing

 

Smart man. No use arguing over it, you still have a CLASSIC that runs well in it's own respect.

you can always turn it into a tire melting, neck snapping beast a few years down the road, haha.

 

Yeah, and I'll be going to college next year. This and my truck are my daily drivers. So with 3.08s and TBI, maybe I can get 17-18 mpgs. And still with 350-380 hp.

 

Man id say +or- 350hp. Should be pretty fast!

 

Dang nice looking car too man! I had a 91z28 i hated the ugly wing they came with. How is that TBI working for ya? Im leaning toward carb when i build my 350 but i am liking the TBI as far as gas mileage and reliability is concerned. I may be swayed into just upgrading it as you have. Wish my car had the 5spd i bet its a blast to drive! You should hurt some feelings with that car good luck

 

Thanks! If you want your car to be TBI, prepare to mess around. It was a lot of work. And I love the 5spd. Would never go back to an auto.

 

Anybody knows what a GXP or a G37 run is a 1/4?

 

Ive saw g37s turn mid 13s

 

That's hauling for a 6 cylinder!

 

And that was stock. Ive saw v6 altimas and pontiac g6s turn low 14s.

 

Think that Prelude will give me any trouble?

 

Not unless he's turbo+nitrous LOL you should wear most these cars out.

 

The gxp and the infinity may be a reach

 

I should really gear my car with 3.77s..

 

Well you got 5 gears so you would be ok and it would give you a few tenths. But best to go with your mechanics advice

 

the prelude shouldn't be any issue. my buddy had a 91 prelude SI with typical tuner mods and i could beat him with my LO3. I run 15.1's just to give you a reference.

With your set up you should beat all of that but i think the infiniti and the GXP may give you a run. Hard to say how much time those 3.08s will cost you. You and your dad should have compromised on 3.42's. I get about 27mpg and run about 1550 rpm at 60mph. As mentioned, you can google the 1/4 mile times of all those cars.

You would have liked my high school class.

79 Hurst Olds Cutlass

I'd say 325-ish. But that's just me...

 

Not sure how easy it would be to find one these days, but my high power L03 car had a 9-bolt with 3.45 gear from a G92 5spd LB9 car. It is ALOT stronger than a 7.5" 10-bolt and worked perfectly with my 4L60E setup. The car I had was 2.73 open, but I never drove it with the 2.73 open EXCEPT off the trailer into the shop to remove the rod knocking L03.

 

I have not seen them quite that quick here in normal air. Most run about 13.8-13.9 @ 100-101 mph. Might be able to go a little quicker with a stick and a good driver. Uprev adds 20-30 wheel hp to a 3.7 though so look out for tuned, "stock" cars. The tuning makes a huge difference.

 

Im sure the ones i saw were probably "tuned" wit basics, exhaust etc.. like most cars are at the dragstrip. I watched em turn 13.50s all day round 106ish. Ive never saw a stock L98 myself turn under a 14.4. Ive saw 5spd LB9s do 14.60. I have saw a G6 do 14.2 and ofcourse all this depends on air temp down south. We typically lose atleast 3 tenths in these humid summer months.

 

I have seen a 5sp G92 speed density LB9 run a 13.9 @ 102 STOCK! Seen plenty of LT1s run low 13s, stock. Seen some LS1s run 12s STOCK.

 

What do you think I will run in a 1/4?

 

I would have 2 see that with my own eyes. I do not believe for one second no 305 turned in the 13s stock ofcourse. I have to call BS on that! I do agree on the Lt1s and Ls's. If u saw an LB9 turn 13.9 it was in no form or fashion STOCK.

 

Id expect your car to turn atleast 13.0-13.2 depending on traction and driving skill with that 5spd. A 5spd is great but as you know an art to launching one with a high torque engine.

 

Even with 3.08s?

 

Well...3.73 would sure help it. Take it to the track and let us know. I do think the 373s would be good for up to 3 tenths on that car. I still think it will pull in the lower 13s with 308 gears. I had a 350 wit stock vortec heads. flat tappet cam 218 218 w/465 lift, 327? gears in an auto with stock torque converter in a 87GTA and smoking the street tires it still turned 13.7 if id had some grip it would have been low 13s. So yea you should definitely.

 

It sucks.. I ordered a series 2 carrier Sunday for my 3.08. I should've ordered 3.73s. But I'll get the mileage I want..

 

Car only has 40K on it and it is very much stock. It is a 1LE, G92, 3.45 geared, 5 speed speed density LB9 (aka "773" L98 cammed), 5spd. Basically the lightest 3rd gen you can get with the most power to the tires you can get in a stock 3rd gen. The timing was tweaked to 10*BTDC, knock sensor unplugged, and the runners iced. Car runs like a bat out of hell for a 305. We were ALL running GREAT times that day. Was about 60*F outside, with the sun out, the track was warm and the air was cool. I pulled a 1.99s 60' in a truck with an open differential and street tires that day, pushing me into the 13s as well. I raced that car about 4 times and it was a drivers race each and every time.

I have since tuned that 305 and it put down 230 RWHP and 310 RWTQ with only chip tuning and 1.6:1 full roller rockers.

 

If it is tuned right you have a 375-400 HP engine. That is 315-340 RWHP or slighly more than a 2001-2002 LS6 intake equipped LS1 6spd 4th gen dyno's STOCK. Those cars could run 12.90s with relative ease in good weather. Your car is lighter and makes more torque. I would think you could hit the 12s as well if the tuning on your car is good and you get some practice launching and rowing the gears.

 

Here's the thing about tuning. I have the 454 throttle body, but the injectors on it made it run rich. I put 350 injectors on it, it idles and runs great. But, I can tell around 4500rpm ( tach reads high) that the motor needs more fuel. Do I need to chip the car with the 454 injectors? Or should I buy some caprice cop injectors and meet in the middle? What should i do?

 

That GXP is supercharged from the factory 0-60 around 5.5 seconds, and 1/4 around low 15.

You said he did an exhaust, what about intake.. sure he didn't adjust the pulleys on that supercharger?

That and the infinity are the only ones I would be worried about.. but if they are all automatic, you can make up having the modified 5spd


EDIT: Sorry, think I mixed the GXP up with the GTP

 

Yes, they are all autos. I need to the car tuned. Anybody know who does them? And yes, I'm aware of EBL flash. It's just I want to get it professionally done.

 

Hate to say it but that Infiniti may have your number. Those cars are quick and have no traction issues on the street. If you get him out the hole you may have a chance but those cars pull pretty hard on top end.

 

Have you had the car on a dyno or had your a/f ratio checked by a wideband o2 sensor?

 

The kid with the prelude just some “stage 3 turbo" BS.. Still think I will win?
