Can a gtp run mid 12s with 300hp and can i run 11s with 2k?

**Z28** · 05-28-2009

Ok so we have an endless discussion going on at my local forum. It consists mostly of gtp bashing, but don't get upset...we are very sarcastic....VERY. We play around a lot and bash each other non stop and post whore like no other.

This new guy is telling us that he can run mid 12s with 300hp. We call BS and ask for time slips or proof, all he can say is that he's heard of other people doing it.

If you got hours to read this thread I will let you.

Is it against the rules to link this thread.

BTW please feel free to sign up and chime in if you want to, we don't mind new people, just behave somewhat.

Basically, what I want to know is:

Can a full weight GTP hit mid 12s with drag radials and 300FWHP?

Can a GTP hit 11 seconds with 2k in mods?

with enough nitrous you can do anything

LOL So agree!!!! I hit like 13.6ish with my stock prix....ONE time! LOL I havent been able to get passed the friggin 14.3 mark since that day! So I would think on a great day a 300hp prix could hit mid 12's. And as for a 11sec...I have no clue! Im sure there is ALOT of things you could do to a prix to get it to 11sec but I dont know about only 2k unless everything you got was used...

**Bio248** · 05-28-2009

the 300 whp mark is usually where people start breaking into the 12s. with a little weight reduction and some slicks i dont see why that couldnt be a mid 12s.

11s for $2k? that's where im skeptical.

I guess that helps prove my point...

So no timeslips, no vids of grand prix's running these times?

There is a crap load of videos of prix running in the 11's and 10s! ZZP I think runs in the 9s...But the whole fact most the videos dont say how much hp or what mods! But im pretty sure your not going to hit 11s for under 2k in a prix.

Ok that helps, thank you.

I'm not trying to hate on grand prixs guys, i own one so don't forget, and I'm a GM fan boy. It's just that these guys are telling me their gp's will hit 12.5 w/300hp and i just don't see that happening...

I'd love to link you to this thread if it's not against the rules...

If its ls1tech im a member. And a proud finalist of the 08 LSX shootout! LOLOLOLOL

No its a very small local forum..i'm part of many forums though. LS1tech is one of them

I had a local forum tell me my car was a waste of time and I should get something better and cheaper....rmm...And its a moms car and blah blah bs! I look at it this way! Ya I have a LS1...like EVERYONE else in the friggin world! There is not very many prix around me that are supercharged or for that matter that are modded! I HATE HATE HATE going to the track and seeing 8237489349874 ls1!!!! And of course you pretty much have the SAME setup as the guy your racing! I like being "different". Ya ls1 FTW when it comes to cheap and fast! lol. But when it comes to the look on peoples faces when you wax them in a 4door "mom" car.....ooo that look will NEVER get old! LOL. If your looking for a car to make FAST and for cheap IMO a grand prix is not the way to go. But if you have the time and money its SOOO worth it!

**99prixgt** · 05-28-2009

you can run 12's with 300whp

**MizzBecca** · 05-28-2009

who isnt part of ls1tech on here lol. i am =)

Eh idk if it'd be any cheaper. I've only spent a few K on mine and it does great. 1 more thousand on a cam swap and supporting mods I could be in the high 11s.

It sucks that you and other people think of LS1's that way and that they are everywhere. Well that just isn't the case around here, which is nice.

But the thing that really hurts though is the fact I've been a fan of GM, mostly because of Corvettes, Camaros, and Firebirds since I was the age of 5. My dad and mom bought be cars to play with that happened to be these cars, my parents drove gm cars, I saw these cars in movies and the Trans Am in Smokey and the Bandit. The day I heard about them stop making firebirds and Camaros I was 17, right before I was about to get my real license. That was a sad day. I still had my walls covered in nothing but pictures of these cars, right next to MJ and David Robison and the 1992 dream team. Of course I couldn't afford one yet and my parents never would let me get a v8 as a kid. So what did I do? I saved and saved, worked 2 jobs, went to college and I wasn't making enough money. Eventually after working a factory job and make 20 hours of OT a paycheck got me enough money, but I didn't have a future. I mean I've always loved these cars. So, when I turned 21 and after I graduated Basic Training, I bought myself a little gift, but then this is what I gotta hear.

"man LS1's are everywhere, all LS1 owners are idiots, Camaros look like catfish, how come you don't have your mullet yet"

Whatever...why do you gotta put me down because I own an LS1 and it happened to have an amazing engine and has an amazing platform? Is that my fault, I'm thanking the GM engineers for making my car an amazing machine in a platform I happened to love.

Put the hate on the ricers buddy, not me

**JoshMcMadMac** · 05-28-2009

Clarification should be made on your horsepower numbers. OP states 300 fly-wheel horsepower, which is much different from wheel horsepower. There are two responses quoting 300WHP, whereas 300FWHP would make out to be more like 250WHP...a big difference.

**FoSHO99** · 05-28-2009

I don't think it matters what you got as long as you like it and you always have the ability to make it unique. I'd take an LS1 anyday, but living in the midwest and being a college student, it just isn't feasible right now. The aftermarket availability of parts for the LS1 is nuts.

That being said, 300whp on average will not take your usual grand prix into consistent mid 12's. There are a few more things to consider, how much weight reduction and such and the way you are asking sounds like its in the hands of an average kid, kinda bold to say it will run mid 12's 300hp. Given that these engines are not dyno queens in no way, they do make some good e.t.'s for the power they have.

There are a few that I know have gone high 11's with minimal mods and a lot of weight reduction +tuning. Ron Vogel went 11.8-9's I believe with 1.9 rockers and intercooled setup, alot of tuning, STOCK tranny. That was probably less than $2k in mods but they made a lot of things themselves.

Personally, I know of a S1X cammed gtp that has run a 12.3 (Gooch). He is probably in the 300whp+ range. His mods are s1x cam, genV s/c, N* tb, 42.5# inj. He probably had less than $2k into the mods including hptuners, but then the tranny went out.

Those are a few examples but I would have to say consistant mid 12's with 300hp is not going to happen for everyone.

Our old L67 swapped 95 Grand Prix went very consistant 12.7s-12.8s on slicks and drag radials and it only dynoed 280whp/290wtq . A good friend of mine only dynoed 260 HP and with slicks on his car we got a 12.77 out of it once but ran very consistant 12.9-13.0s. I honestly dont think much of dyno numbers because a dyno is more of a tuning tool than for comparison and I have never seen two dynos read the same. For example a few years ago we had 3 shops with chassis dynos. Two were using Mustang dynos and one was using a DynoJet dyno- that is where we go to dyno but they have recently sold the dyno. The DynoJet numbers were ALWAYS at least 25-40whp higher than the Mustang dyno numbers which really pissed off a lot of guys going to the Mustang dyno! A good friend of mine only put down 380whp in his Camaro on a local Mustang dyno yet he runs 11.3s at the track on drag radials in full street trim and another friend of mine with a mustang that was running mid 10s didnt even hit the 400whp mark on that same dyno so after one pull he told the guy to shut it down and take his car off, he was very mad to say the least! This clearly shows that dyno numbers dont mean squat sometimes. It is a good tuning tool to make changes the same time the car is strapped down to tune and get HP improvements. If you go back a different day the weather will likely be different and the car will put down different numbers regardless how much supposed compensation there is built in to the dyno. I feel that an honest 325whp would give you solid mid 12s on drag radials with decent track conditions, not a one time or one night fluke but every car is different and this is just based off of what I have worked on and seen at the track over the years.

Supercharged 3800s dont make high HP numbers but the torque is what makes these cars run the impressive numbers that they do and traction and driving skill makes a huge difference in times at the track. About 7 years ago all of the fast guys in the community were dynoing in the 340-350whp range and running high 11s back to back with track prep but a lot has changed since then.

As far as LS1 cars, there are a lot of them around here too and they definately are impressive engines and nothing I would ever knock no matter how many there are! There was a point in time when the 5.0 Mustang era was huge around here and thats what everyones thoughts were.... "Theres another bolt-on Mustang biigggg deeaaallll" I honestly dont have much of any interest in most V8 stuff anymore because of the potential of these 3800 engines especially with turbos and all I can say is To Each His Own. Everyone does their own thing and at least in my mind I could care less what someone else thinks, I build my car for ME

Enjoy what you have man, there are tons and tons of upgrades out there for the LSx engines and at least you are rwd! A few years back a friend of mine had an 01 WS6 TA with the ram air hood. The engine was bone stock and he installed long tube headers, new air box lid and filter, 175 shot of nitrous and a custom tune and the car ran 11.9s at 121 on drag radials and would eat faster cars up top on the street. I always felt the engine was a ticking time bomb but it never skipped a beat and in my eyes that is pretty insane to get out of car with next to nothing done and some spray! Another local had an 04 GTO with the LS1 and had a 150 shot on it and ran 12.5s at around 116. Both cars were autos with stock rearends and drag radials and both were nasty on the big end so if you planned to race past the 1/4 on the street you were usually in trouble lol.

**SlowM90** · 05-28-2009

You need to come to Arkansas! Or for that fact come south! Believe me! All you will see is Camaros or Trans Am most are LS1 powered or LT1....They are everywhere! And your grand prix is running 11s? Or your camaro? I have more money into my tranny (camaro) then I do the whole car and it still won't hold the power! Its not that I have a FASSSTTT car its just EVERY bit of the hp is going to the tires! And IMO the 4L****tE is well...just that! LOL

**blowfishRus6** · 05-28-2009

guys make just as much fun as mustangs. you know why there is alot of ls1's around?? because there easy to make fast, duh it dont take rocket sience, same with the 03-04 cobras.

on my local forum (muscle car forum) you see alot of ls1's and not nessicarily in camaro's or ta's. one guy has it in a van

and of course you know the camaro and mustang guys go back and forth all day. you see alot of 5.3 trucks 6.0's somtimes swaped into camaros. but mostly gms that are going fast. there is the 2v and 4v mustangs (not 03-04 cobras) but there nothing impesive. hell most of them are getting stomped by trucks. but i am to at this point.

all i can say is i get called out alot by people thinking its just a slow grand prix and well most of the time they get DRUG

i love the grand prix just because you dont expect it to be fast.
