Comptech supercharger - advertized gain versus usable gain?

Well, truth is... I sat on the SC for year before I installed, casue I was worried as well.
In doing so I have been monitoring here for the last 3 years. I only know of 2 blown headgaskets and 1 blown motor... all of which were due to running the SC in a NOT STOCK config.
- Way back in 2006, one guy (Can't remmeber screenname) was running Juice and the SC on the track... likely without any tuning. Boom.
- Dan K blew his headgasket running the HBP
- USSI reported some trouble with SC HBP, but never fessed up to what it was.
- lookinco blew a headgasket... but for all i know, that was all a tall tale.
- Some guy local to me (guy witht eh 2 tone tl) is SC, he blew a ring due to "washout" from a sparkplug failure... ? Something fishy there.
///and in 3 years, those are the only SC blown motor I've been able to find. Even though it's unfortunately poorly tuned, it seems very reliable to me, otherwise it wouldn't be on my TL either.

My opinion, many who discuss how bad the surge is, have actually never experienced it... yet they "worry about it" like the car don't run right.
Is there a bit of surge? yes, I find it barely noticeable. The surge is characterized by a bit of stumble as the blower kicks in as you pull therough the 4000-5000 rpm band. Could it be better... I'm sure. It's the best of what's available right now, so why bitch? If Hondata or anyone else comes out with a batter map?full ECU tune, I'll likely for that later... but the car is definately a blast as is now... anything better is icing on the cake.

Kennedy,
Thanks for the good summary.
Add Cocoa to the list. I know his is not exactly a J32, but the same family of motor (I think).
See post #63 on page 3 and post #109 on page 5. He blew the head gasket and lost a few piston rings while using a 100-shot of Nox.
Thanks for the good summary.

I've decided to get the Type-S anyway. Its not worth justifying 5k=$$$$ for the S/C when it comes factory with almost 300hp. Not worth it IMO.

FWIW, buy used. I got my blower, with lots of accessories (UR pulley, meth kit, gauges) for $2800 and installed it myself... 1/2 than 5K.
Get yourself a lightly used 2006 6MT and start the modding (exhaust, suspension, wheels..), then jump on the first used blower you see in the Black market (we average 2-3 a year sold there)... All said and done, you'll be $8-10K cheaper than a TL-S, and have 30-40 HP on em.

There's a limit to NA mods... and those guys in the TL-S are at it. Completely free flowing exhausts and intakes seem to get you about 275-280 on "high reporting" dynos. Other's with similar mods are barely breaking 270.
That's it. Ain't no more power to get without bigger displacement, Forced Induction, and or Juice...
Racinhart, in his TL-S is putting down just over 300 ON THE JUICE... He could he retool and put a 100 shot on for dyno pull, but that motor won't last long.
A base 6MT TL, with some good exhaust mods, and a SC has been shown over and over to be in the 320 HP range. Those numbers came before big Jpipes came out too. I'd bet I'm in the 320's right now... well, when it cools down a bit.
No TL-S will ever be there without a similar investment in more air and more fuel...
