LS4 Performance - Trans Am WS6 vs Monte Carlo SS

Last night I raced an LS1 Trans Am with Full Exhaust and headers 2wice from a dig. Both times, he barely beat me by a 1/4 car length...he couldn't pull on me at all and we probably took it to about 80 or so (maybe a different story if we pushed passed 100). I am diablosport tuned and stock tires that are in serious need of being replaced. I'm surprised I launched as well as I did...he probably did about a 1/10 better in his '60 foot which is why he had the slightest lead. I bet with a normal tune that has TCM support (ahem) and some nice summer tires, I would have taken this victory.

Oh crap here we go again.

:jest:

if you were that close on that standard canned tune, you could'a taken him with a custom DiabLew tune! ;)

Nice runs, it's good to keep up with cars like that.

im 2-0 vs my buddys 04 GTO on the street. my only mods are K&N and exhaust hes got the lingin CAI and an 05 exhaust. : ) all of his GTO buddies mock him endlessly for losing to me twice. We just threw a set of Micky ET streets on his goat and now hes beggin for a race....im tryin to hold out :engarde:

I would love to race an ls4 car with my gto (use to have a gxp). A 04 should be quicker though even, did he have an a4 or m6? I havent lost yet in the gto, ive beaten an ls1 z, 2srt-4's, 300 srt8, couple mustangs with intake exhaust gears,, and an aveo (ex girlfriends :) )

Tell ur buddy to get a real intake as that lpe intake is crap. Its a hot air intake...nothing cold about it

I raced my budies LS2 GTO but he had Intake, tune, Headers, Full corsa exhaust with X pipe. Got him off the line to about 20 then he was gone. He put down 370+Whp. He just got a supercharger on it and now make 582wHP

lol I know he should have destroyed me. i told him lets switch driver seats and see who wins.

Oh crap here we go again.

Just so everyone knows before some LS1 dude comes in here and flames about their stock superiority, I'll admit I was surprised at the outcome. He technically should have taken me pretty easily. Obviously, he wasn't driving the car to it's full potential. But a the end of the day, it's all about how you use what you have and I'm pretty happy with the results. So please think about that before posting flames.

Actually you need to give the ls4 cars more credit than that. I think the ls1 should win, but not easily. I had a GXP and it is still a fast car, and im sure it would still seem fast to me now. I actually got a taste of my first ls1 goat today. I beat it by a few cars, it was an a4 and we were roll racing, but he had no chance.

Well the guy I raced had full exhaust and headers at least (he said so). So I'd imagine he was putting down significantly more than a stock LS1. All I have is a tune and bald tires...

yeah these cars are definately underestimated by the f body crowd i ran my buddy bobs trans am last summer i was bone stock and he had intake Ls6 mani and full exhaust i kept up untill we hit about 85 then he smoked... he was suprised anyway i think as long as we keep the races around an 1/8 mile they dont get as much of a chance for their car to pick up the slack

Well I’ll be dammed this is going a lot more civil than I anticipated. Dam good driving guys. I haven’t had a chance to play with anyone since my last bolt on, but the wife had a G8 GT start picking on her going down the road, so she kept he’s front bumper with her fender till they got stopped at a red light. When the light turns green she walked away from him. She shut it down at 60 and was already ahead of him by about 3 lengths. I could not believe she beat him off the line.

Oh crap here we go again.LOLOL!! :engarde:

I know my GXP is no match for my SS hahaha

I have a few buddies with close to stock LS1's and I'm itchin to run with them soon (in the GXP)

i have a 06 monte ss and just sold a 2000 t/a with a built ls2..............

the t/a was faster by far

but i agree people underestimate the ls4...it is a very capable car, and suprising how many people think the ss monte still has the 3.8 v6

my monte ss has beaten my chevelle (with the wife driving) with a built small block from stoplight to stoplight... we did it because i knew it would and she didnt beleive me...

just my 2 cents

Damn, I like my 08 gxp but I must have a slow one.Some cars are just faster then others stock. I have no personal experience racing a LS trans ams or camaros but I have with the lt1's and my car doesnt seem close. I had 1994 and 1995 Firebird formulas that ran 13.8 stock. I have had plenty of 350 tpi cars that ran 14.2 to 14.0 and my Gxp seems closer to those cars. I would think a LS camaro or firebird , especially one with exhaust work whould whip all but the most modded cars on this forum. One car magazine took a stone stock 2002 camaro ss to a 12.98 quarter mile. I'm gonna have to get this thing to the track and see what I've got.

ok full exhaust ws6 vs stock monte ss ?lol im callin bs.your talkin 320 vs 260 hp,man that guy cant drive for sure.i have a 92 richard petty edition 3.4l dual cam m5 grand prix about 220 hp w/cai vs a stock 07 monte ss i had a half a car from roll about 55 to 110 at 107 his governor shut off as i kept pullin,he stopped and asked if i had major engine work,i said no just a driver mod,he was speechless.

Come on don't short change us on horsepower, we have 303 not 260. Could be possible the guy just wasn't a good driver. Stock LS4 cars can dip into the high 13's. Then again stock LS1's have been known to dip into the high 12's. And you weren't racing an 07 SS if he was limited to 107. The LS4 cars are typically good to 154.

If he hit a governer around 107 it was a V6.

And would explain why he smoked him in that car.

Someone didn't read my disclaimer:

If you think it's BS, then more power to you. Just telling you all what happened. Take it or leave it. It is what it is and it happened. If you don't think that a car with more horsepower with a poor driver can't be equaled or beat by a well driven car of lesser horsepower, then you're in a dream world.

If you guys are talking about the 3800, I had been well above 107 when I had my L67 monte.

No he's talking about the newer 3500 and 3900 V6's in the 06+ cars not the L67 cars.

Our cars really don't flash their power around. When I was test driving mine I took it out on an on-ramp and stomped the gas down just to see what it would do. I didn't hear a lot of engine noise or feel the car leap forward or any of the stuff I associated with LS1s I'd been in. At the bottom of the ramp I'm like 'This V8 is crap, crap, crap. *glance down at the speedo* Holy shit I'm doing 110+ mph.' More often than not I find myself out on the highway doing 90 or more because the car just kind of quietly creeps up there, tap the gas for a moment, no loud growl or anything, the needle just moves higher and higher.

In terms of other LSx cars we're close enough its a driver's race, assuming comparable mods of course. FWD does burn our asses on launches, but if the other guy can't launch it all levels out. I've been stock and modded LSx cars, lost to some, it all evens out in the end. I kind of dig the sleeper look though and all the direspect I get. It makes showing them my tail lights ever so much sweeter.

The smaller mod community does hurt a little. I miss having a F-Body and all kinds of easy mods for it. With the LS4 just start saving for the turbo and racing transmission basically.

I love my 06 monte ss but that 91 lumina z34 I had w/ the 3.4 twin dual cam was a cool car for its time. I actually miss it, not pulling the motor a few times over its life span, but beating up 5.o stangs was fun. LOL

i like monte ss... good race!

I'm with you on this one. I've had friends run crappy times in Camaro SS's. I remember when one of them got a 2000 SS, ran 14.1 stock. Just because they're capable of low 13's doesn't mean the driver is. He ended up learning the car and ran 13.30's.
