Huh???

Please expand on this statement.

 

scalbert,

hope the baby -borning process is going smoothly

 

good luck with the new job Andy. Unfortunately there aren't enough kits out there, and probably not local for you to get a test ride. I rode in/drove a few cars when choosing on my $4000 turbo kit. I had the luxury (because I travel for work) of actually going to the shops who make them and touring and asking questions. I believe the CT SC is probably a good product based on their rep and the one product of theirs I've held in my hands (and installed). Modaddict and Nashua make good points about looking at the area under the tq curve and not just looking at peak numbers. For example, here are the kits I was choosing between on the dynodyno My car is the APR with stock intercooler, the PES is a friend's with front mount intercooler. Both on the same dyno same day. As our hp looks the same and peaks very similarly, you can see my tq is a bit stronger down low. He peaks a tad higher in tq. My turbo is a ball bearing and spools faster than his, but mine still flows as much air as he does. I went with what I have just because I liked the components better overall, and I like the shop who made them a whole lot better. The other nice thing is that we have a board for owners of this kit so we can alway shoot info and ideas around and not get them lost in a huge Audi forum.

Anyway, the choice is simpler for you, just one kit out there for now. The one piece of advice I will give you is to make sure your car is 100% before doing this. Any little issues you might have will be amplified when adding FI. It would also be a good idea to have a compression test done before install.

I just looked the CT website again. Damn it is pricey fow what you get. Granted you are paying for the CT name, the fact that you have a higher end car and the fact that there is no competitive kit out there. To put it inperspective, my turbo kit costs less than the SC kit. But that's apples to oranges and there is a bigger market for my kit than the CT SC.

not sure if you have looked the CT site recently, but there is a dyno of the SC with headers/exhaust. 265 to the wheels! 6 speed gets 299 to thw wheels....hmm maybe I will get a 6 speed CLS

Modaddict, I wasn't refferring to you or taking a shot. I was just saying how it's hard to go drop the $$$ like this with so little unboased inout out there. It's not like there are people on the board raving about this kit and saying they have xxxx trouble free miles with it. As much as it doesn't matter, 1/4 times, but more importantly traps are usefull too. Of course your dyno numbers tell the story well too.

Now that mention it, I would like to know a few things. These are things I would want to know if I were in the market

1. how have intake/coolant/oil temps changed?
2. any issues with the kit, even minor ones. Any check engine lights?
3. any installation tips? From pics I've seen it looks very straightforward, but it's always good to know. Sometimes little things can be a pain.
4. What is the fuel system upgrade? It's not clear on teh CT site. I assume they go the less expnsive route with an FPR, not larger injectors. Although for that price I would prefer larger injectors. If they do use a larger FPR, I wonder if the injector duty cycle gets maxed out? What is the A/F ratio under full boost?
5. Any pinging or knocking since you've had it? Especially on hot days?
6. Have you driven in snow? I wonder hot having all that low end tq is on snow.
7. what oil do you run?
8. is the ECM a piggy back or replacement for the OEM?
9. How has the auto tranny help up with the kit?

 

Actually everything has been pretty well documented in this forum and one member has over 10k miles on his blown CL-S6. But to answer your questions in the order presented, of which are already documented:

1. Boost is mild at about 4 PSI as the base so there is minimal thermal loading on the system. So the stock cooling system is handling it fine.

2. No CELs that I am aware off. I did experience a problem with the FPR which might have been my doing but that cannot be confirmed.

3. I did a full write up in three separate threads. This included pictures and tips on additional tools which might be helpful.

4. With the mild boost level a rising rate regulator was used; a 12:1 unit. Larger injectors are worthless without a reprogrammed ECU or a piggy back computer. A rising rate regulator is good for up to about 8 - 9 PSI boost.

5. On the stock pulley there hasn't been any knock issues I am aware of. I had some with the higher boost pulley but that was traced down tot he FPR issue I mentioned above.

6. The snow issue will be just like any other vehicle, judicious use of the right foot is required. But not a problem for me in the south though!!!

7. 5W-20 Amsoil Synthetic. But others are running something different. This is all irrelevant to the SC as it has its own internal oiling system.

8. Nope, as mentioned above. There is ESM which clamps the MAP signal so that the ECU doesn't see any positive manifold pressure. This is the extent of electronic components.

9. There is a transmission oil cooler included with the automatic kits.

But IMO, all of the above is well documented in this forum; a simple search would provide the required responses.

 

good info Scalbert...thanks for catering to my laziness. Another question I have....anyone runnig an intercooler? I noticed you are fabbing one? I'm not trying to put down the kit, I'm jsut trying to get some info for my friend who started this thread. I'm not sure if he knew all that you mentiones since I don't read this board all the time.



yeah, this is why I asked. I thought this to be the case.

 

So I take it you purchased the kit???... do the install yourself, it is not complicated... 2 pieces of advise, you will find better directions and more insight on this forum than the CT instructions and make sure you research and do your homework before you jump in....

C/T kit Pricey?..... can't afford it, don't buy it... but you'll look at putting a 4K turbo in a car.... not to mention all the tuning required....

Instead of expensive aftercooler. How about a CAI Cryo Cooler for "hot runs" : http://www.designengineering.com/cry...ir_intake.html

 

this is true for most products unfortunately.

yes it's very pricey imo...there is very little hardware with the kit. I bet they are making a pretty large profit on this kit. They didn't have to put in much R&D compared to a kit with chip tuning. But that's what tuner's do when there isn't a large market to soak up the cost of R&D. And with no competition, there is no reason to lower prices. I don't have a CL or CLS, so I won't be buying it.

As for the kit I have, it's a lot to spend as well. But the volume dealt is much greater. There are hundred of the kit I have out there. My kit has:

garrett GT25 ball bearing turbo
Inconel Steel wax cast exhaust manifold...Audi sport sells a similar one for like $10k
High flow catalytic converter
larger injectors
colder spark plugs
Inake hose SLA's by the Tuner
Outlet hose made by Samco
oil line and fittings
coolant return line and fittings
engine mount
I already had an engine chip from this tuner, so I didn't need a new one, just a software upgrade
SOFTWARE with home programmer so it can be updaded whenever new software is released. This software lets me store up to 4 programs on my ecu and I can change programs on the fly using my cruise control switch. programs are 91 octane for the west coasters, 93 octane, 100 octane, 104 octane, valet (no boost and 4k RPM rev limit) and there is even a stock boost (8 psi) program in there too.

Again, comparing apples to oranges here, but I feel like I got my money's worth. Can't compare kits for different cars in different aftermarket segments. If I were a CLS 6 speed owner, I'd be stuck between the comptech and custom turbo idea. I'd probably lean towards the turbo since Allmotor has done so much work already.

 

None available which is why I am making one.

 

Actually there was quite a bit of R&D in this kit as there are little nuances with the various platforms. The blower its self including the cross drive shaft would run in the neighborhood of $1500 - $2000 alone. The remaining cast aluminum pieces, etc are well thought out and well made.

In the end, Comptech does charge a premium but they do back up their products well too.

For ultimate power the turbo is, without a doubt, the best direction. For moderate and very linear increases in power for a daily driver the Comptech SC is definite worth every penny.

My original plan was to install the SC and forget about it; enjoying the power increases it gave. But that lust for more power has caused me to change my plans to where maybe the turbo would have been a better choice. But for now I will make the most out of the SC kit as there are hard limitations such as the blower speed.

 

I have read this thread, and it looks like the best dyno on here is ~250 HP. Maybe I'm not following this correctly, but so far I see the SC gaining approx 40 wHP for ModAddicts car.
Now my question, What's up with this 330WHP Comptech car? I keep hearing about it. Is that the blue CL-S 6 speed prototype cl that comptech has? Has anyone ever seen a dyno that high?

I'm looking at maxing out the car with all comptech parts and they claim to be able to get it up to 300+whp. Has anyone ever seen anthing in this range?

I'm starting to thing that this is the typical 30hp headers + 50hp SC + 10hp Icebox = 90hp gain, etc.. That does not mean when you put them on the car you'll get the combined gains. I'm not trying to
put down these mods, I'm really into modding my CL-S Auto now after getting an Icebox. My thing is, I don't want to spend 10 grand on SC/headers/etc.. if I'm only looking to max out at 250whp.

Anybody have any comments/dynos to share that are actually getting these gains that I hear about but never see? Or know where I can find any further info/dynos on this comptech prototype car with 330whp? Or, if I'm way off here I apologize. Can somebody please clarify this for me?

Regards,

Jon

 

You haven't looked at any 6-Speed dynos then; also ModAddict doesn't have headers yet.

6-Speed Dyno

I went but the numbers lead me to determine the FPR was having problem which is now fixed. I will be going back to re-test my car.

Comptech's dyno shows 299 WHP, not 330. They have acheived nearly 330 on their test car but that included many other items.

 

Ok, Thanks for clarifying that Scalbert. So, on an auto Cl-S what is the best we can hope to gain with all comptech parts? The 299 must be a 6speed then, but have they produced a prototype car in 01-02, or have they modded up an auto themselves?

Thanks,

Jon

 

I didn't think you were taking a shot at me, it's only that I've never seen anything but good, technical, information here, except for the $$ per hp discusions that always seam to pop up, or the people that won't change their intake w/o the 1/4 mile times to justify it. I have 10k miles so far, and all is good. Scalbert missed the high flow fuel pump that also comes with the kit. I spend most of my time on the highways, in the heat of the day, with high humidity, and no knock issues, with the high boost pulley. I have not had it in the snow with the S/C yet, but will log quite a few hours in the snow this winter. I had a couple of long trips in the snow last March when the car was new and it handled fantastic. I was very pleased with it in stock form. The nature of the bower alows you to drive it without boosting, so hopefully it will be as easy to drive this winter. My car was built in 01/03 and is supposed to have all the current transmition changes, again, so far so good.

 

Good info guys....thanks.

 

No, I haven't bought the kit. I got cold feet and I don't know if the exra 40whp is worth $4K. That is a lot of cake! Jeez...

I really (REALLY!) appreciate all the help. A little friendly pushing would be okay. ;-)

Sticker shock is a harsh mistress. But throwing down 265whp would be nice....

 

Oh, and Modaddict, do you feel safe in the snow? I can barely feel safe w/o the SC since even off the lot the car wanted to roast the tires. The SC just makse it that much worse.....but man....do I want that!

<<rationalize: it is only money!>>

 

There is a giant snow making machine just to the west of me called Lake Michigan. The lake effect snowfalls are relentless. Without the S/C it was a great car in the snow. With the S/C I am able to drive anywhere without going in to boost. The day after I installed it, I drove across the state and back and got 30.7 mpg. You can ease into boost without even knowing it. You have complete control of the acceleration. It's not going to all of a sudden blast off like a rocket,.....well, unless you want it to!! So yes, I feel as safe as you can feel, driving in the snow.

And oh yea,.....it's only money. And the install is not hard, it takes a while, but it's not hard.

 

I think that I would be too scared to do the install myself. I would feel better having a pro do it. That is too important to mess around with IMO.
