We're starting the install on a 6 spd manual GS early next week.
Follow along to see what the new Heartbeat will do.

Sorry about not updating, we've been swamped and have had a couple of guys sick so the updates slipped my mind. 
Install is done, just waiting to get it on the dyno. Dyno operator/tuner is one of the guys who's been away, so we're backed up. Hope to get it on the dyno next week.
A few more pics.
I'll do my best to get the dyno results up as soon as we're done.
Thanks!

First set of results are in.
This is with the Magnuson CARB legal tune, we're at 4000 ft above sea level, this is with 91 octane and 6 psi.
We'll be doing some custom tuning and then see what we can get out of it.

Curious
I know this is a year old thread, however did you ever custom tune this and what were the results?
Also what RWHP are you getting with headers and a custom tune?
thanks

This car dropped boost due to the headers, and at the time, smaller pulleys weren't available to bring the boost back up.
Now that smaller pulleys are avail, we typically see 560ish RWHP at 5 psi with headers.
Hope that helps.

After adding the long tubes and tune it made 543 RWHP and 504 RWTQ.

When you changed the pulley, did you have to upgrade the fuel pump?
thanks

Hope that makes sense?

No fuel pump upgrade required because we just bring the boost back up to 6 PSI. When the headers go on, the engine has less restriction so the supercharger shows a lower boost level, we change the pulley to bring the boost back to the same level as it was before the headers.
Hope that makes sense?

that's pretty impressive for 5psi on a (presumably) stock cammed car!BTW: Was the test car referenced on this thread an A6 car? I only ask because although the initial post says the install was in a 6 spd Manual GS, the red GS in the photos must be an A6, since it's not a dry sump car. If it was an A6, those numbers are even more impressive.
Have any of you guys in Canada experimented with exchanging the lid and taller intercoolers from the Camaro version, or have any of you done anything with the LSA drive pulleys?
What about throttle body/TB snout modifications?
We're having a discussion on another thread about these things and whether the same works, but there seems to be more questions than answers with modifying this blower.
I'm waiting on my HB kit to be shipped to me, so any info you can share on this blower would is greatly appreciated.
