yes...

 

25-35rwhp from a CAI ...I'm thinking that estimate is a little on the high side...

 

Nope that is what they usually get.. The stock airbox and air filter is like a big cork for the blower.. I have seen 03-04 cobras Dyno as much as 440rwhp with a stock pullie, stock manifolds, just a CAI, O/R X pipe, catback, and tune..

 

Oh, well I did not realize the stock airbox/filter was so restrictive on a s/c cobra. Learn something new on this site all the time...I just thought it would be more like 15-25rwhp...actually that is probably what I will believe until I see some proof.

If I see a dyno of a stock cobra and then a dyno with that same cobra + CAI, and it shows a 35rwhp gain I will, first of all, **** my pants b/c of the cai gain, but after that gets cleaned up I will believe it...

 

On an N/A motor you can gain up to 15rwhp with a CAI, not you take the cork from a blower and it is going to make alot more power.. Just makes perfect since, and I have seen it too..

 

Good kill man.

K+N advertises 31 RWHP gain on 03-04 Cobras with FIPkit. THEN you can actually HEAR the S/C...

 

I agree with you, and think you are correct, but for me personally I would just rather see it for myself, ya know?
Sure, theoretically an n/a motor can gain up to 15rwhp with a cai, but in the real world it is more like 8-9rwhp, right?
Well I am just applying that logic to the cobra. Sure, theoretically it can gain 35rwhp from a cai alone, but in the real world it is just not going to happen like that except maybe 5% of the time.

 

It's cool. I understand why you are hesitant on believing. Just three things, Plenty have seen those results (snoop around SVTP), Blowers LOVE Cold fresh air (that is a fact), and I used to own a Cobra Vert.

But again, it's cool, and I understand. I am skeptical on some things, even if multiple people tell me.

 

The problem is that you're comparing a forced induction car to a naturally
aspirated car. They respond much differently.

Uncork a blown car and you'd be surprised what it'll do. 20rwhp is common
for just a CAI.

 

Are you shure? My SS weighs 3410lbs with NO weight reduction at all,CD changer,power everything,leather,ect. and thats with a full 10 lbs nitrous bottle that adds another 24 lbs.

 

My 3480 trans am has a full nitrous bottle, baby seat, heavy *** yellow top battery, and a few other bits and pieces that add weight.

 

rofl.. stock ls1 dont put down 305-315.. more like 280-320 depending on year and tranny. you need to calm your *** down; honestly, i dont really give a **** what your car dynoed. like i said DRIVER ERROR on that 03-04 cobra. read what i wrote.

ps i didnt see that you had LT.

 

well i don't know about 13-18 rwhp. let's be realistic here......more like 5-6. you gain 18-20 more with long tubes. i dynoed 354 and 367 with the same mods you have and my cutout was open. keep in mind dyno's are never the same. on one dyno you can get one number and on another one, you can be + or - 10 or more rwhp.
and for the record.......that Cobra cannot drive. congrats though on you advantage to drive better than him though!

I'm 1-2 with the 03-04 cobras. I won one race by a car; another one was dead even with a cobra with intake/catback, and i got smoked by a KB cobra.

 

i dont see where 305-315 isnt in the range of 280-320. and im a manual, so most manuals will put down more than 300. my *** is calm, i just dont appreciate when someone, especially a fellow f-body owner comes and bs's my thread, and if your going to bs someones dyno numbers again, fully read the thread first. my mods are in my sig. i even said in the thread that it was driver error. the guy who owned the car couldnt drive worth ****.

 

i was just going by what ive heard from other guys who have cutouts about the 13-18.

you have an ls6 intake, which is still hurting me because i have the ls1 intake still , and my cuouts were closed. is yours with a tune too?

i know dynos are never the same, the only reason i chose this dyno was because it was the same one i dynoed when my car was stock.

and i do know i would not pull like i did on a cobra with a good driver.

 

01 ws6 m6-lid, hpp3, lt's, ory, cutout closed 348.3rwhp 352.7rwtq
cutout open 352.1rwhp 362.4rwtq. at the track 1.964 60' 12.525@112.52mph.


good kill on the cobra. i can't wait to run one when my car get back together!!

 

Hello ladies and gentlemen, I would just like to step in for a moment to clearify some dyno numbers. For those of you that don't know me: I was the proud second owner of LastLt1's SS. I have all the paperwork including window stickers and dyno results in front of me right now. When I dyno'd the the car BONE STOCK (paper air filter) it put down 297.5 rwhp and 308.1 rwtq. Hundity was 39.8% and IAT was 102*. On the same dyno, the car (current mods w/ cut-outs closed) made 352.55 rwhp and 357.85 rwtq. Humidity was 44% and IAT was 96.69*. So if anybody has any additional comments/concerns about questionable dyno numbers or dyno "tricks" I assure you that all of the above numbers are 100% accurate and I personally expect a low/mid 12 second run from the car next time we make it to the track. Just my $.02. Happy motoring to all!

 

i was proud of my car when it dynoed 318 @333tq, lid only then on dyno day up here in va a stock 02' ws6 pulled 316

 

Dan brought up the naturally aspirated car for comparison, not me....I realize they respond much differently.

That is exactly what I am trying to say. Exactly. My entire point was that 35rwhp sounds a little high, and might happen 5% of the time, but 20rwhp is most likely the norm. You hit the nail right on the head.

 

I never said a 160 thermostat gave me hp did i ***** ! i said that was all done to my car when i had it tuned when it was mostly stock . My tunner has been doing this for a good bit of time now tunning lots of ls1s . Matter of fact that is the only type of car they tune so they know what they are doing . Im sorry your car didnt put those numbers down stock maybe you should fire your tunner and give mine a call my car ran 8.19 at 86mph in the 1/8 ( which is high to mid 12s in the 1/4) when i fist got it after the dyno on a safe tune for the 100 shot . stock camaros at that track i run at run mid to high 8s on average. I hate when people question everything even when you have the proof right infront of there ingnorant face! Hell i have a video if you want that too ! It was also 90 degrees out that day also .And this was a little while back so those numbers are not even current to my mods and ets now !
