I beat one in my 200,000 mile 1993 Cavalier Z24 with a 3.1 that was rated at 140hp when new. If you think those mods knocked a full second off of there 1/4 times you are in need of help.

Guys, this firebird put down 330 RWHP and 345 torque............thats more than the average full exhaust LS1 car........................but if this thread were talking about a race between a full exhuast LS1 car and the lightly modded TC I'm pretty sure we'd all be talking about how the TC is going to get walked...so....????

And a 3.8 fireturd is lighter than you think, definitely NOT 3600 pounds. I have no idea where you guys pull these numbers from, but they are WRONG. Hell, last time I was back in Arizona, I went to the track with my buddies 1959 4 door Pontiac Catalina, we rolled it onto the scales at the end of the track, got out of the car, and with a half tank of gas it weighed 3,950 pounds. You are telling me that a HUGE ASS 25 foot long boat of a car from 1959 only weighs a few hundred pounds more than a 98 firebird? Nope.

the auto 3.8 birds weigh in at just over 3300 pounds

He is using the one piece, so he thinks his rear end should be all set

holy shitballs!

There u are!

LS2guy

Have some respect and call the damn car by it's name if your going to defend it.

But you are right not even my fully loaded Trans Am GT weighed 3600lbs, all of my 4th Gens LT1 and LS1 weighed around 34XXlbs.

As for comparing a turbo 3800 F-Body to a LS1 you need to compare more than just peak power levels. The LSx engines make power right off idle to redline without drops or peaks that are sometimes common with custon turbo set-ups.

The 4L60E isn't **** and if it can hold up behind a LS1 it will do behind a turbo 3800.

And the open diff allowing massive spin is most likely keeping shock load to a minimum saving the drivetrain anyway.

I put a large wager on the Turbo 3.8.

I coordinated the sale of my aunts 1997 5spd V6 Camaro to one of my friends. Mint condition 65,000 miles and the fully loaded 30th anniversary edition. It was the last year of the LT1 style exterior but had the interior of the 98+'s. It was just as nice on the inside/out as her 2002 SLP SS Camaro. My friend payed $3500 for it about a year ago. Since then he turbo'd it with a 62-1, put a moser 12 bolt rear in it along with a few other things and it spanks my GTO. He put down 450whp and similar tq on pump gas and stock motor. I think he's in under $10,000 for the entire setup including the car.

the ls engines really dont make too much power off idle, those motors you really do rev them out to make good power. but your right about the peakyness of a custom turbo setup. hopefully they used a good sized turbo for the car and can get a ton of torque and good hp off the line

LS2guy

Take a peek at a stock LS1 or LS2 dyno graph and get back to me on that one. Look at where they start making major torque that is 1,400rpm above idle which is impressive. We aren't talking about DOHC 4.6 liters here.


Well christ that thing must run 10's then since your GTO is the "fastest ever" GTO with so little mods.

PhantomSS

Wow "my firebird is only 3300-3400 lbs!"

Let's add a 200ish lbs driver

Firebird is around 3600 when you drive it

TurbochargedFuture88

car is definately a fatass, but its still going to be a close race, well a masacre from a dig, but from 40 up, it should be within 2 car lengths either way. probably going down this weekend

yes with a 200lb driver the firebid is 3500 pounds and with a 200lb driver the cobalt is 3200pounds

still only a 300lb difference

SLoW SHO

My GTO isn't the fastest ever by any stretch, I ran an 11.9 on cheater slicks and a 12.2 on street tire. OMG SO FAST

PhantomSS

That's fast and I don't use that word often

I said 3600

And we have 3100ish cobalts IMO so the shoe fits

LS2guy

You know as well as I that you didn't run those times with the mods you claim to have.

SLoW SHO

He used quotes as if I claimed to have the "fastest ever" GTO and I'm quite short of that feat and would have never said anything remotely close to that. I think he's just offended that my lightly modded GTO would take it to his C6

LS2guy

Your full of **** that is why I put it in quotes, you didn't run 11.9 with LT's and a tune.

1BADSS/SC

Im thinking the LS2 weighing in at ~3200 lbs would take the LS2 weighing in at ~3700 lbs. Just a thought that almost 500 lbs difference may slow the GTO down quite a bit.....

idunn

grenade, the diff shall!

1BADSS/SC

Yea...... OOOOK.............

compucarnut

I ran 1.6 60foots all day long on slicks on my Firebirds puny little stock rearend, probably launched it a thousand times. Never blew. Go over to thirdgen.org and do some reading. There are LOTS of guys keep into the 11's on the stock rear. Hell there are even guys into the mid 11's on the stock piece of crap T-5 thats supposedly only rated at 225HP. Its all in how you treat the car.

For that matter why aren't we talking about the Cobalt's axle's going BOOM? LOL.

1BADSS/SC

thats a whole nother can of worms

1gmfanatik

I'm a member on there because of my 91 Camaro RS with a 350 swap. A lot of good info there too..

By the way, the Cobalt SS/SC's are the ones with the axle issues, not the SS/TC's. The axles have been upgraded in the new Cobalts.

INDColtsFan18

I say firebird will nose it out from a dig, cobalt will take the roll race by a car.

SLoW SHO

Yea the extra 50whp my car puts out over a stock LS2 would make no difference.
