Rocket,
your point of testing the a$$ out of these systems before they go to public would cost them $1000's supports my point in every way.
Something they've tested on a limited basis, and rely upon the consumer to test and fix the rest of the way is wrong!!! <---I'm thinking of baby beds here....remember back in the day when they were recalled only after a baby's head would get caught between the bars or once a baby died after getting caught between the mattress and the barred side?
They have saved alot by cutting corners, asking for a premium, and letting you all fix what never worked properly. That should be worth more than an IC, they will profit off of your work, R&D, and off of the chance that your F20c may suffer a terminal failure, not theirs. I have yet to see of any written guarantees, or extended waranties from Comptech of installing their supercharger on your engine.
Oh yeah, I've heard the argument that they will only honor any fixes as long as the Supercharger went in by professional hands that they approve of....but obviously, they themselves aren't profesional enough to be able to get one Supercharged S2000 functioning properly. <---WTF?
If you blow your motor due to the Comptech SC, do you have enough faith to trust they will make it right? Do you have enough money and time to go to a lawyer and court?

Harry,
I spoke with Don, the owner, about your "hesitation" at around 6000 rpm. He says that is a dip in the power band due to the fact that the low rpm lobe has gone past it's power peak. This can be seen in the stock power curve, it just gets accentuated with the supercharger. With the supercharger the thing drops about 5 ft lb. of torque around 5500 rpm, then takes off like crazy at 6000 rpm. This isn't something that a ghostbooster-type item will affect at all because you are already well into boost. By the way, have you removed that early check valve from under the MAP sensor and installed the other valve yet?
We've been testing an electronic "fix" for stopping the boost signal from reaching the ECU. The testing involves measuring the voltage signal, among other things, and at this point it seems to perform the same as our current check valve setup.
Luder, You may not be aware that we had this supercharger in development for 15 months before a single one was shipped out. Even with all that testing, there were some conditions that affected the original check valve that we had never been able to duplicate. Trust me, it wasn't like we just threw the kit together and started selling them and expected the customers to do the development. I think you'll find many customers who will tell you about the efforts we've gone through to fix the problems that arose.
As for your comments about warranty coverage, maybe you should read the inside back cover of our catalog. We have a two year warranty on our products. There is no requirement that the installation be professionally done in order to be covered under warranty. And if an engine gets damaged due to a failure of a component of the supercharger, the engine would get covered also. We have an insurance policy specifically for this. And in almost six years of selling superchargers, we have yet to have an engine failure.

I too would like to tip my hat to Comptech. It always amazes me to see the time and effort they put into their customers, including me. I have nothing but the highest respect for them and look forward to future dealings with them.

With respect for davepk's and SilverSurfer's comments, I do not have the luxury of being near to your shop to receive the staff's TLC (or free work) nor do I expect to have a burden of tuning (as all three of us have had) on a product that is sold as a "self install" out of the box.

I just thought I would chime in here too... My supercharger experience has not for a second removed Comptech from my 'top list' of tuners that I have worked with. If I had to make a list, Comptech and King would soar at the top with absolutely no one close. The reason? You call them and every person you speak to GENUINELY cares about every word that comes from your mouth...
Okay, now to the blow off valves. I think the only way Comptech could have guaranteed the success of their valves would have been to use them around the US (multiple altitudes) in a wide variety of weather conditions. My one valve would stick at certain temperatures but the next revision would stick at completely different temperatures/conditions. All hesitations occured around 4500-5000 rpm when the boost is building.
Sure, I built the GhostBooster and use it instead of any valves and I still love Comptech. The kit was beautiful and installed extremely easily... if building a small circuit is all that is needed for perfection... well great. If we all wanted a 100% running Stook 100% of the time, we shouldn't have modified it in the first place!
BTW, I will be 1st in line to pay FULL price for their boost upgrade kit... I also wouldn't buy anything like that from anyone else because Comptech does SO MUCH testing before they release a product to the public...
Just my opinion.
