Also, I like how everyone ignored my comments about nitrous

I'm sorry to make you guys feel bad about your cars, if you were modding a Mustang GT the power/$$$ ratio would look pretty good!

You say MAYBE 400 hp with a stage 2/heads/cam setup?

WTF?

For $3500 dollars you could go with something like the Colonel has, Stage 2 LS6 heads and a stealth cam, he's making 430 RWHP, WITH AN AUTO. Put in a little bigger cam and use a 6 speed and you'd be at 450+ RWHP.

Making you look like a dumbass after throwing your info back in your face... even better!

Or you could go with:

Stage 2 heads: $900
150 Nitrous Kit: $800
Cam + springs: $500

Oops, don't want to make the STS owners look bad

 

You've been reading LS1Tech too much. Not every heads cam combo will make as much power as you state and the ones that do have tons of blood sweat and tears into it. I like how you conviently leave out all the hidden costs of heads/cam/nitrous installs....

Like I said before, where's your dyno sheet so we can compare????

Maybe we can compare before and after 1/4mile times if ya like??

The combo you talk about can indeed make tons of power but is it the only way to go? NO....

I don't feel bad about my purchase. Hell I feel better about it than when I did the heads/cam/nitrous/big stall route on my T/A... Only think that I bought that made me happier than the STS kit was a 351w/ S-trim combo in my old Mustang :p

 

lol. this thread trips me out.

Anyway.. I'm not a fan of the STS kit at all. It breaks all the rules and I don't see it as being effecient. You guys keep bringing up meth injection and big boost. Untill I see some results that are higher than a well running heads/cam/bottle car, I say you're all smoking the meth.. lol

If it'll make big power numbers do it and back it up. so everyone will shut up.

 

I don't understand how you can say it's ineffcient and doesn't put up #s. How much HP/TQ does an ATI kit put out on a basic kit? 400-450??? Is it also a bad kit?

I already put up good #s for a 5.3L truck. Even the #1 Truck in the mags and on the internet right now only did 500rwhp with a 6.0L and front mount T76 on similar boost. So it's not far off IMO...

But yeah, maybe some LS1 CAR guys will up the boost and put out something big to impress the skeptics. As for me, I'm done with dyno crap. I'm putting the intercooler on today and looking for timeslips since dynos are less impressive IMO.

 

Read the title of this thread (very, very nice turbo setup on camaro) I don't know how this turned into a pissing match , but this kit was perfect for all the reason it was designed for. Ease of installation, great performance gain over stock, fuel economy and drivability. It's perfect for daily driving and especially towing. I've gained 128rwhp and 139rwtq @ 5psi and gained 2 mpg city,hwy and 3.5 mpg towing. See if you can do that with a h/c combo.

 

What I'm getting at is the rear mount kits are inefficient compared to a conventional turbo kit where the turbo is located under the hood. They just won't produce as good of numbers as a more efficient system. I believe they will also have trouble making big numbers like you guys claim they are capable of. I understand why the rear-mount kits work, and are not debating that they do. You guys just don't understand how turbos work and what makes them efficient. You are claiming they will make big numbers with meth. I say do it. I want to see you making better numbers than a conventional setup. By all means prove me wrong.

With a turbo under the hood the turbine wheel is very close to the exhaust ports. You loose a lot of exhaust temp within even a few feet of the engine. Loosing this heat is loosing energy that is spinning the turbine. With the turbo in the rear, you'll have to run a smaller A/R turbine housing to help increase spool due to the loss of heat. This smaller housing will decrease lag time, but in return be more restrictive thus less efficient.

Pressure drop on the compressor (intake) side of the turbo is also going be a low point. With the long charge pipes and possibly an added intercooler there is going to be a lot of pressure drop. This means you have to generate more pressure at the turbo to see the desired pressure in the intake manifold thus working the turbo harder.

Lets say you have 5-6psi of pressure drop with a rear mount kit and an intercooler. This is a lot of pressure drop. You are generating 5-6psi more at the compressor housing which also produces more heat on the intake side. So a kit running at 5psi would be running at 11psi at the turbo. 10psi would be 16psi at the turbo, and so on etc. You need more energy from exhaust heat to make more boost. Think about it… this ends up being an inefficient circle of energy loss.

I'm not saying this kit won't work, I'm just saying it's not near as good as a conventional kit that follows all the rules of efficiency.

 

If that's what you want, more power to you. I completely understand the advantage and disadvantages of turbo systems vs blowe, NA, and bottle setups. I have plently of experience with turbos.

I'm telling the guys wanting BIG numbers not to hold their breath.

 

This was not directed at you in any way. You do have an open mine about it.

 

Thats what I have been trying to say F8L... THIS kit is on par for any forced induction kit making 5 PSI...

Soooo... do you guys just have STS envy??? or are you against ALL Forced Induction?

BAD2000SS Made a couple of assumptions that are incorrect.
This kit will do all the 10 things I posted before. With a good tune, it will pass emissions.
He commented on tuning it rich will fail emmissions. So the 3000gts fail Cali emmissions? How about the SRT4's? 2003 Cobra's??? Sorry that does not hold water.
To the best of my knowledge, the kit has passed all the CARB tests and STS has paid for the EO, now it is going thru the red tape for approval. And last, the same shitty fuel in CALI affects you just as much as me.

SO I ask again... Show me an H/C setup that can pass the 10 VALID points in my previous post. STOP trying to invalidate mine, because I KNOW that this kit fits the list.

Z98 Do you honestly believe that ALL Colonel did was swap H/C and made 450HP... your high...
MTI LS6 heads = $1600 + exchange
StealthII = $400
Nitrus=$800
Gaskets bolts=$200
Install=$500+ dollars
What about headers $300?

Now... with that setup, I concede that you will make more HP than ANY F/I kit running 5PSI. BUT this kit will give me the 10 things that I posted before. And was MUCH cheaper then the next competitor... which I believe is $5000

And add to my list... gets better gas milage.
Say what you want... it serves its purpose and not too bad a price.

 

Thank you wildman

 

cool deal. I hope you like the kit. I understand why you have one and that you don't exspect to be the fastest thing on the street. They are border line cheap and make more power than a stock setup.

I just find it really annoying to read posts from people thinking its the best thing since peanut butter. I understand it will make more power than a stock car, but there are enough bs posts in here that I might as well be reading clubsi.com.

I used to be very active in the fi area on another board. This new setup came out that everyone thought was the shizzle, but it just never really produced the results. Eventually it sorta dwindled away. I reffered to it as the "chrome *****". Everyone wanted one because it was so bad as, but when they got it they realize it wasn't all it was hyped up to be and just looked pretty on the board. At that point they all had excuses for their dyno sessions and still went along with it being the badest thing on the planet. This kit sorta reminds me of the "chrome *****".

Anyways. Hope you enjoy the kit. Do you know Scream with the LS1 powered gmc? He's a local buddy of mine.

 

Perfect. If it works for what you need and makes power that you are happy with, i'm happy to hear it. I'm just sick of all the B.S. claims and arguments from both sides.

"It won't work"
complete bs.. it will work in theory and obiviously backs it up.

"It's just as effecient"
Sure it is.. keep believing that.

"It it's sooooo fast"
ok fast is relative. I personally don't consider a 3500lb fbody with only 450rwhp fast

"It'll make XXXrwhp, just wait till I get my meth.. you just wait!!!111!1"
riiiiiight... lol get off the bench and make the numbers. prove us wrong.

 

I'm with Wildman as well. I think the kit is a great alternative to higher priced turbo options. Yes, the kit is in the back of the car, how much difference does that make performance wise? My money is on not much. Put the exact same turbo up front, and I'd bet there are no tangible increases in performance. Dyno runs may say it's better up front, but I don't even think it would be worth half a tenth in the quarter.

 

Not being an *** or anything, but...

Do you consider your 11.7 fast? What if said 3500lb fbody with only 450rwhp ran an 11.5...or an 11.0...or a 10.8..or even faster? Would you consider it fast? Or do you determine how "fast" a car is based on how much horsepower it produces?
Dyno numbers are a tool used for tuning, nothing more. Track times are a measure of performance.

 

If the turbo was located up front, you should be able to run a good bit large a/r housing and acquire the same spool up times. This would return more HP as would the increased efficiency by using more energy from less heat loss of the exhaust gases. Less pressure drop on the intake side would also be present. With the same quality of a tune, the more efficient conventional system will make noticeably more power and definitely have more potential for more power in the future. You get what you pay for.

 

It is NOT as efficient as one under the hood... But that CAN be worked around by a bigger turbo and a few other things... But then that Turbo won't be as efficient if that turbo was under the hood... Endless loop.

THe truth is, after the effeciency debate and sizing, it has the same limitations as any other F/I system.. go higher than 5psi, worry about going lean. The other thing is 5PSI is 5PSI... It might not be as efficient... but it is the same 5PSI that another system would make... no?

Just food for thought.

 

Nice Jab. lol

The 11.7 pass isn't my "fastest" or best time. It's more of a joke. Low ET for high mph. My car would have trapped 132mph or so if I would have take it back. MPH shows how fast a car is on the street. I hate to make claims of what ET's it would have run with tires actually on it, but is capable of 1.5' 60's with et streets. You do the math.

 

If you're planning on staying at 5psi they 5psi is 5psi. When you start wanting to actually make some power you will be limited. smaller a/r housings also typically render less top end power too.

If you try and make big numbers I'm pretty confident this setup will run out of steam.

 

This kit was never intended for max effort turbo applications. If I wanted to make a "big number" with heads and cam, I wouldn't do it with stage one heads and a 224 cam either.

 

Excellent. I'm glad you understand that. Some people here seem to think they are going to make "BIG" numbers with this kit. I'm just trying to bring reality into their little world.

In addtion, thanks for taking a blow at my "slow" ET.
