who will win in a 1/8 mile? her's has the supercharged v-6 that accelerates like a motherf*cker.

Soon as my step-dad gets back from iraq we're gonna goto jax raceways and dual, i think she'll win hands down, but is this true? My mom is too not race smart to drag me so she'll wait until my step-dad gets back.

My car has a Edelbrok Cat Back, and accell high outputer distibutor cap, currently, but by then it'll have headers, CAI, and all the free mods.

Back when I had a 350TPI I had one of those mo-fuggers walk right away from me on the street (rolling to maybe 50). They are fast man...I think the 305 will be its b1tch! :hail:

therckid

crap so i wont stand a chance unless pretty heavily modified huh?

IROC_385Z

Don't bet anymore than 20 bucks on the race

But let me say that you have a VERY pretty car though! That GTP will never take THAT from you

therckid

i know my car is nice, but i willbe prepping for this race then, i would like to knwo what kinda numbers i'd need to be pushing to beat this thing. As i can tlel from just driving it ti will win hands down, by like 5 car lengths.

IROCaholic

Yeah youll get smoked. What gears to you have? Ive heard of those GTP's going mid 14's though the best I have seen is low 15's. So your gonna need at least headers and a full exhaust, a high flow intake setup, at least 3.42 gears, a well setup suspension, oh and 1.6 roller rockers which will raise the lift of your cam about .30. I think you should easily take her with these mods, but then again I dont know much about 305's or TPI. Good Luck.

IROC_385Z

hmm...search the internet, im sure you kind find times. The GTP, I would imagine, has to be running 14s.

I just dug this up...http://dc-vc.net/dc/toybox/cars/

This one is modded and runs a wide range of 14s...i would guess you are probly in mid-high 15s.

therckid

240 HP, and its lighter, means i need around 270 to beat that thing, g*d damn, i'm never gonna win. I'll need some good *** shizzle to get even to a 2 car length loose.

Man, shane thinks baout the $5k he'll never have for a a new engine.

therckid

i'll need a 350, i'll get it from these people

http://www.precisionperformanceengines.com/

cheap high end performance engines.

IROC_385Z

Thats a good price for the power...its basically a hopped-up factory motor.

350 /360 hp Street Heat $1,799.95

Cast crank – GM 5.7” rods – ARP rod bolts
GM 70cc heads – 2.02”x1.60” stainless valves
Edelbrock Performer RPM intake (Holley)
Speed-pro 291`-.447” lift hyd. cam


This looks like it'd be a fun motor...but unless they modded those heads I think that may be too much lift. Ask them questions about it before you buy.

350 /410 hp Hot Street $3,199.95

“Eagle” cast crank- “Eagle” 5.7” I-beam rods
VORTECH heads –2.02”x1.60” valves
Speed-pro forged 10 to 1 pistons
Edelbrock Performer RPM intake (Holley)
Speed-pro 305`-.510” lift hyd. cam


Whatever you decide good luck!

Also let me note that a few weeks ago a kid that my brother knows came over with his 305 berlinetta. Now up until this point I had NO respect for 305s. I had been in TB and TPI cars and they just seemed slow. Well this kid had like a 222/222 .500 cam, Torquer 305 heads, and it was all topped off with an edelbrock 600 (get a 570 street avenger) but man it was fast! It may have been the fact that he was driving like a maniac but it really moved once it hit 3000rpms....i never though those motors had it in em!!! Just know that it is possible if you do it right.

therckid

i like fuel injection so it must stay. I'll find a way.

therckid

even though those come with intake manifold for carb alreayd, i will sell it on ebay i guess.

Ravicai

What engine do you have?

I think the battle would be pretty close if you have the 350 tpi, 3.2x gears, and posi-traction.

2000 Grand Prix GTP are stuck with a 4-speed auto tranny and typically run high 14's stock. With a few mods they can easily hit 13's though... so in summary, don't show your mom this thread.

SOLID LIFTER

GTPs run mid 14s - low 15s. Your mom is going to p0wn your 305.

nolanr0413

you will get killed, plain and simple, i raced my dads 00 gtp daytona 500 edition, got wasted. He ran a 14.7 @ 92 in the quarter. And that was when the car was stock . He now has a reprgrammed pcm, u bend removal, 160 thermo, 2 range colder plugs, thrasher cold air box, and a 3.4 pulley. The car runs 14-14.3's. They are fast stock and faster with about 600 bucks worth of stuff. For about 1000 maybe a little less you can run 13s on street tires.

Ray87Z

I raced a couple back when I just had a mild cam, chip, freemods and a catback with my old 86 IROC and pulled on them. With the addition of headers it bootkicked the last one I raced. I'd ditch the peanut cam, for under $100 you can get a decent replacement like the one I ran (204/214 @.050, lift of .420/.442)... That alone will give you a darn huge increase and at least allow you to put up a fight... Get some headers as well as you were planning to and you'll take it out IMO...

therckid

so what might you suggest, in the lines of mods todo, to get the best outcome, withoutusing Nitros!!!!!!!!

GTATransAM

Dont know if it was mentioned, but how about adding as well some slicks and a torque converter, that should really scream off the line. I know a friend who tells me to get these 2 things, but i just got done putting other stuff, so low on cash atm.

therckid

stfu, and leave my thread now

IROCThe5.7L

My friends GTP pulled about a car on me from a 45 mph roll. At the time he had exhaust, pcm, and a 3.8 pulley I believe.



Your best bet is to race from a stop. FWD and lots of torque don't mix well.

therckid

hey can one of those GTP morots fit in our cars? Its got the same style motor mounts right? Or would that bea big bummer to install?


And my mom just got new tires on her's for some reason thr stock tires had very small amoutn of rubber on the road, but these new ones hell i can barely burn out on it now.

therckid

cause that would sorta be like a GN engine except its supercharged and not turboed.

Not even close, totally different motor, totally different setup.

Mad-Mic

your toast. my GF's 98 GTP with cutout and pulley runs low 14's.

johnh

Stock GTPs run anywhere from 14.3 to 15.x. Just depends. Pretty easy to mod too for under $1k you can get to 13s. Some are even faster....

Club GrandPrix 1/4 mile times

antivtec69

Heads intake and cam with some sticky tires and a nice stall would probably do it. Good luck and hopefully you dont get beat too bad.

IROCThe5.7L

I'd sure hope so!

therckid

Well duh thats like gettigna new engine pretty much. If i got heads and cam only i'd be able to take her. Head are the mottle neck of the engine. If they peformed as good as they would like to in theory then all would be awesome. But they dont. So i'm gonna try some Dart Iron Eagle Heads, and a nice cam, but i dunno mines not a roller block so that would be a bit complicated.



Shane

IROC_385Z

Goto the junkyard, spend a few bucks on a 350 vortec from a 90s GMC truck...cam it up (factory roller) and boom. It'll do everything you want for a good price.

ljnowell

A few bucks? He may be better off working with what he has.

IROC_385Z

Yea, i used the phrase "a few bucks" a bit loosely there...but it is still cheaper than heads/cam alone...let alone those crate motors he is looking into. For the money you should just get the bore-bore motor.

See the second to last line in my sig.

He's dealing with a 305....

IROC_385Z

EXACTLY!

nolanr0413

so did u race and lose yet . I dont think im gonna run any gtps any time soon , we just went to lebanon valley for musclepalooza the 30th of may and my dad ran a 13.83 @ 99 with our gtp, and we got 29 mpg on the way down. SO they are fast with some mods. The car has about 700 worth or mods and it ran that fast . from a 14.7 to a 13.8 . So they can be animals with some money .

Hope you have $$$ set aside when that garbage of a tranny lets loose Good 'ol GM for ya

vampiroc

guy with 305 BUY SOME SPRAY. hehe that little 305 is pretty stout, should be able to handle a 150 shot without a problem if you're in good tune for nitrous (retard timing a bit, richen the fuel/air mixture). you can pull low 13s on a 150 shot out of the hole with traction and show that GTP what's up ;'). other than that, you're SOL unless you throw about $1500 in parts and a week or so of labor installing new heads, cam, aftermarket intake, new chip, full exhaust, and removing emissions equipment to run 13s on the motor.

BigWhiteGTP

If you want to have a chance taking a stock GTP, ask your stepdad if you can fill the tank up with the cheap 87 octane, and again fill it up. A whole extra 120+lbs in the back right there. Also, get the engine nice and hot. These cars run like **** when above 200*. Ask him to put traction control on....unless it's a 97 like mine and tell him not to torque break it. Doing those 3 things and you should be able to hang with him, if you get a good jump. Then by 60 he'll pass you.

A stock GTP puts down 265lbs of tq to the wheels.

Btw, my car hit a 13.93 with a ****ty 2.17 sixty ft with just a pulley, basic exhaust, race gas and a Home depot intake.

Good luck!!

therckid

well i got 1-5/8" headers with a 3" collector on my floor right now, i just found out i have a shift kit and aftermarket runners, so....

SOLID LIFTER

You're still going to get beat.

fly89gta

iTrader: (1)

Yup

92HeritageZ28

ive heard that some can hit 13's with just a pulley.

pskel350

pretty much, 13.5 with a pulley, intake, pcm, and DR's....

they can be fast cars, and they are cheap and easy to mod, which makes for a mean FWD car. fortunatly i have to much expereince working on them, and know not to race some of them.
most likely you will get beat

GP trans are not that bad, differentials are a different story however. 12.8 on stock tranny

therckid

well then i'll make sure they loose

KagA152

iTrader: (5)

get those headers, the shift kit, runners (port plenum at the same time) and i bet youll take em, especially in the 1/8th. :zips up flame suit: got a light with a gtp w/exhaust, i actually pulled a good launch on the street and had like 2-3 cars to 70 and that was when i had just a cat back and free mods

kretos

i've been browsing through the forum and seeing a few of your posts. instead of asking whos gonna win go to the track and race if you loose you know the answer.


cus we have yet to see any results from this one or the dodge stealth


and i'm not trying to rag on ya man, i'm just trying to say that we can all say that your car can be faster, but anything can happen at the track
