What exactly is a cam only LS1 and do they really run 10's-12's?Basically if I put a cam in my car it might see 12's but never 10's. I just read about a cam only LS1 running with a pullied cobra and keeping up. I just don't see it happening. Maybe I'm misunderstanding something. How can a cam give you so much power. Please let me know because I have a friend that say's our cars are a pos and that his 03' terminator is the **** and that with little $$$ he can get alot of power.

Dont know much about how much power the cam will give you, i do know it depends on the cam tho. haha. I have read many stories about "cam only LS1" sticking with cobras.. Oh yeah, and Camaros and Trans am's arent shitty... The only reason he can mod his car for so cheap is because he paid a hell of a lot for the car itself (Due to the S/C)... Dont get me wrong Terminators are bad ***, BUT SO ARE LS1's

Finkledbody

From what I've been reading, a big cam (where the cam is producing all the power above 4500 rpms) only f-body pushing 400ish whp with weight reduction (talking 3200lb or less race weight) with sticky tires, suspension, a4 with 4.5k stall or bigger, 4.10s, with a great driver runing 10.80-10.90's. Doesn't happen all the time but its doable with the right set up.

I haven't seen any Fbody's with 400 rwhp in the 10's........ Unless thats 400 rwhp without the 150shot they are hiding........ Most of the guys are at around what? 600rwhp that are in the high 10's on a N/A car?

400rwhp seems to be good for mid to low 12's......from what I have gathered, and with !weight and stall/gears mid to high 11's.....

there are guys with stock internals that have gone low 11's N/A, and cam only have seen plenty in the 10's, we are talking about a LOT of weight reduction, Big stalls, Big gears, etc

top three guys on the list in the tens N/A with stock heads/cams, just bolt ons, big stalls, and a ton of !weight

had me worried for a second Los, thought maybe you meant i bumped an old thread even though i seen it at the top of the list, then i realized you just meant how long it's been since cam only ls1's in the 10's were common knowledge, my bad

blkjck

cam only is a bigger cam on stock ls1 heads..theres a member here (armyz28 i think) that has a cam only ls1 with 436hp.. (i believe)

this debate has been going on since 04'
is what i meant. we've all been there. if u own a ls car. the sc cobra vs ls car will always come up in way or another eventually.

good god this thread should be locked...... check the cam only list found in the drag racing results

https://ls1tech.com/forums/drag-raci...s-engines.html

theres plenty of us running 10s low 11s w/ cam only setup

cam only= doing everything except the heads

ive made as low as 440rwhp and as much as 456rwhp

As Demonicbird00 said, cam only is just that...cam only. Basic bolt-ons are assumed. The next step past cam is heads and intake, but bang for buck, a cam alone delivers a lot. My buddy's 04 GTO is cam only and he puts down 408 through cats. He has a FAST intake that he hasn't put on yet. I'm sure he'll see some good gains. The amount you get from a cam depends on the cam...you can get anything from mild to extreme.

Your buddy is just talking **** or knows nothing about LSXs. Most Cobra / Mustang owners respect that engine. As far as him saying that he can make huge gains for a little bit of cash, he's right. As others have said, the Cobra comes stock with an Eaton supercharger. A change in the pulley diameter will result in large gains by spinning the supercharger faster. A tune is a must. If he's smart, he'll do supporting mods also.

Just do more research. If you're a true fan of fast cars, you'll look on both sides of the fence. I'm always looking at what the other guy has or is possible of doing. I like all cars in general, and even if you don't like a brand, it's always good to know your enemy, hehe.

i have ran across this alot in the past few years


a buddy of mine had an 01' ss camaro A4 bone stock except 2 things, 4,000 stall converter and 4.10 gears......

he ran against a 04' cobra of course the cobra is a 6 speed it had a pulley, full exhaust, tune, and 4.10's as well

they ran like 4 times at the 1/8mile track where im from and they were close but the ss won every time, the ss ran 7.40's consistently and the cobra ran 7.50's ...... thats sad when a 310rwhp car out runs a 550rwhp car

i had a 02' ss 6 speed at the time it just had a trex cam, exhaust and 4.10's and i ran 7.50's launching easy cuz i still had the stock 10 bolt

on the freeway the pullied cobra would pull me by a car or so but i would stay right there with him...... thats sad when i dyno'd at 418rwhp and he was at like 550rwhp


im guessing its the torque curve that trex cam gives you, cuz on paper he should wax me but that cam i had would pull hard through the rpm range....... especially later on when i put spray on it


to give you a good comparison, i took my 02' ss camaro straight off the showroom floor, drove it normal for 3,000 miles changed the oil, bolted on a nx 150 wet kit and got some drag radials, took it to the 1/8 mi track and ran a 7.50 totally stock except for a 150 shot

thats the same time i got when i went cam only, and thats the same time the pullied cobras were running


so yes you can hang with a pullied cobra with a $400 cam but if you really wanna wax em then get a cam and spray if your car is a m6 or cam and stall if your car is an a4......

a stall in an auto car will dyno very low but will run a really fast time. dyno numbers arent everything

Poor cobras

550rwhp on a pulley, exhaust, geared Cobra? Impossible, unless the numbers on the dyno are inflated. A non-ported, stock Eaton with a smaller pulley will average 450-475 rwhp.

ARCTIC '00

You must always consider the weight of a vehicle among other things when using horsepower to estimate e.t. There are several "bolt-on only" LS1 cars in the 10's and several dozen in the 11.9 or quicker index, all well under 400rwhp obviously.

camscam is running a Magic Stick cam with untouched241 heads and he hit high 10's N/A with the car not gutted. did have a stall gears and suspension i believe

It isn't impossible, most cobra with just a pulley and exhaust with a tune dyno on the average of 475-480, there are ton out there putting down right at 500 with stock unported eatons. 550rwhp on a non ported though is total bullshit. The cobras weight abit more then the camaro's an 03/04 non vert cobra weights in at 3800 pounds!!!! The car has an independent rear not solid rear axle, a solid axle swap with 4.10's and bolt ons run 11.30-11.50s all day long, its amazing what removing 300lbs of sprung weight can do!!!! IRS robs alot of power double with is weight over a solid axle.

LSx motors are bad *** for sure. The 4.6 motor is no slouch, John Mohovitz owner of accufab, has a cougar for pro 5.0 with a lincoln mark VIII teksid block, fully built of course twin 88mm turbo's and his car runs 5's in the 1/4 quite frequently, he is the only mod motor in pro 5.0.

I have watched a ton of lsx cars hand cobra's their *** and vice versa. Dyno numbers don't mean jack. I have one of each, My lincoln mark VIII has an 03 cobra motor in it, I promise that an 03/04 is probably one of the hardest deals as far as best dollar for dollar mod/car to beat. Stock the block can handle close 1000hp. It comes with a forged Steel crank, manley H beam rods, manley custom blower pistons(skirts are weak point they have a shitty coating that could cause problems it isn't often but does happen) The cams are custom blower grinds, rear end is full IRS with 31 spline axles and 31 diff. 6spd that is alittle stronger then the stock LSx transmissions. For 15-25k car, that can make 750rwhp with a 3800 kenne bell, whipple, or splurge and get a Twin Turbo kit and make 1,000hp. Not many cars have that ability.
