<%cynic%>i think this is a sad, sad answer to the problem of poor throttle response in the SC. "deal with it. If you do what makes the SC work like it should you'll have to keep buying inferior quality aluminum brackets from us." why don't you make a new steel bracket, or magnesium or titanium or something that won't fracture from the proper level of responsivness from the unit??? <%/cynic%>

You ghostbooster users correct me if I am wrong, but all of you had a NON "plug n play" version, with the circuit inside the car and electrical connections made thru the ECU harness. Therefore, the map sensor configuration on the engine would be identical to a non-SCed car(?).

all this circuit does is select which map sensor gets read. The implication would be that throttle response is so good that the brackets can't take the sudden application of power!

Shad, if you have more information than just "they all had ghostboosters", please let us know, as I am still considering building one, even tho current performance seems pretty good.

 

I am the other, 3rd, customer that has experienced broken brackets (yes multiple brackets on multiple occasions). Let me also say that up until Sunday I would have never believed it possible that the electronic fix could be the cause of cracked brackets.... But I'm now convinced that when it is in use brackets break... though I can't imagine how or why this should be the case.

For a little historical info please see this thread....

I have now had brackets break on 4 different occasions. The working theory after the first two failures revolved around a possible faulty installation by Modacar. SilverSurfer and I both had our SC

 

Okay... Ghostbooster out... hesitant check-valve back in...

I guess our really cool fix with superior throttle-response was too much for the aluminum mounts...

I wonder if my new shoes will be a problem: they might allow my foot to press the accelerator too fast, open the throttle too quickly, and damage the aluminum mounts...

 

Shaner, Have you been running the GhostBooster??? and no cracked mounts??? Are you using the stock ECU??

 

I'm not trying to accuse anybody of bad judgement/logic/yadda yadda yadda, per se, but...

If an improved sensor allows the SC to operate at it's full 'design-in' potential (i.e., it shouldn't hesitate, and this new sensor removes that hesitation), then it my complaint would be with inferior brackets. After noting four failures on one engine with the booster and no failures (so far) with the booster removed, I would begin to agree that the new sensor was the cause (or at least partially) of the bracket failures. However, this should point out that the brackets DO need to be beefed up to make the SC act as it was designed to act.

I agree that the sensor is having some affect, but don't rip out the sensor and keep the hesitation, keep the sensor and create new brackets.

My two cents...

 

According to the info I got on this board.
The Ghost Buster electronic fix made the SC'd car better and the original check valve fix is no that good.

The problem should be a below standard brackets design.
Comptect should redesign their brackets with better materials, stronger ribs,etc... increasing the safety factor.
Blaming customers for fixing their products don't help sales.
If they can fix the brackets and sell their kit with the ghost buster fix. I would be a happy potential customer.

 

Our major concern here is if there is enough force going into the 6061 t-6 alum. mounting brackets to break them, what else could be seeing the same forces? (rods, intake manifold, cylinder head, etc.?) Yes, the easy fix would say lets just make stronger brackets, but its not realy fixing the original problem. Until we do some more testing we are recommending that you remove the electronic switchs. The data is showing us that the cars with the electronic switchs are cracking the brackets and the cars with the vacuum check valves are not. Thanks,

 

No offense Shad, but telling customers to continue to use the vacuum switch, which clearly doesn't work very well to begin with, isn't solving the primary problem either. If the system works right, no one will bother with work arounds. I can understand suggesting the original switch while you guys come up with a solution (to prevent a more catastrophic failure), but that does hurt drivability.

Now, can someone clearly delineate the failure mode of the bracket? I'm having a hard time understanding where the cracks are occurring, not to mention how different switches can cause such a problem. I can't imagine there is that much more torque with the electronic version (nor would I be worried about the rods, etc.).

Hey all,

Sucks about the SC problem but Comptech is not a sponsor of S2000Online and as such the use of the site/bandwidth/storage for providing service and recall info is not permitted. It sure is convienient to just post a message (especially since 99.9999% od the SC's they've sold have been a direct result of this site) but there is a cost involved and they don't want to pay it. Therefore I would recommend that Comptech licks stamps or posts this information on their own site.
