Is stage 3 DOA now then? No word anywhere regarding it.
Richi, any updates? They take the blower back?
it’s just air in teh cooling system. Should be ready in a few months.
they’re sending out a new supercharger unit. they changed the machining to a few components of the blower. the blower should arrive today or tomorrow and ill have it installed next week
:o
Guess the people on this site weren’t so stupid.
Richi, Glad to hear things are progressing… Hope this gets worked out… I can assure you though there is no way Eaton changed components of the blower based on feedback from a few test kits that Magnuson sold… Remember Eaton is primarily a tier 1 OEM supplier to all the big automotive companies… They fed you, or RSW, or whoever a bunch of BS… Not trying to be an ass just realistic… Will this new blower require a new tune?
Let me rephrase. They didn’t touch the blower itself. The tooling is on the manifold
Hopefully everything works out for you.
But just seeing as how APR had such trouble getting this working for so long I have some doubts that magnuson is able to fix it in a couple weeks. You think if the fix was that easy APR would have already figured that out?
Thanks for the clarification… Maybe Bernake helped them? ;D
Look at my reply #137… lol
137 was me

which one did you mean?
Doh! 113, my bad…
Maybe there’s more to the blower not being great. After someone (Sak?) said the corvettes were having problems, I read a little on the forums. The Z06 ECU pulls timing and goes into protection at even slight cooling issues, it seems, plus chev didn’t add enough cooling capacity and airflow to help. Maybe this isn’t the most efficient blower around and chev knows it too? At least compared to the 1320?
Or maybe Magnuson got the casting tolerances/expansion coefficients for the materials wrong. Reading the patents on the TVS, there’s a lot of mention about how the shape was designed to promote an efficient blower, and from my experience with twin screw vacuum (fixed pitch just like this blower) that clearances, especially once at temperature, are a huge concern once thermal expansion and coatings are factored in. In our similar pumps, the difference in clearance and vacuum from cold to 90 degrees C is very significant. Anyhow, just a shot in the dark given that they have to re-machine.
I’m sure there are a LOT of specification if someone else (Magnuson) was to make the housing for the Eaton-made screws. Must have gotten it a little wrong somehow?
Eaton patent:

In unrelated but funny patents:
somehow Edelbrock patented the front-inlet, front-drive roots blower/manifold?

And: the twin-charger patent is gone! Sorry SRM lol

Maybe something with the heat exchangers?
Asides from the res height lol.
Yes true - the heat exchangers may be crappier than the OEM ones. You can directly compare the two designs (single pass, double pass) theoretically, and the APR single pass is potentially worse by 7 degrees C at full load:
Here’s what I posted in the other thread.
In defense of Bernanke, I wouldn’t have even thought to look if he hadn’t been persistent with his idea.
Ha. Yeah, I guess we’ll see if there are any changes with the res.
I had a hard time keeping up with everything in the other thread, but that’s a fairly significant difference. I still don’t understand why they wouldn’t have done an upgraded dual pass version of the OEM units. Why cut corners in the one place you know this kit is already vulnerable?
If someone will finalize a date and track I would gladly make an effort to come out.
I can do Toronto, Sparta/St Thomas, Thompson.
I feel like Toronto is too far for Ron and that Sparta/St. Thomas is the nest choice.
Too add my experience to the discussion
I have been running the double pulley setup for a while now, all of summer. I have been running the 104 octane program with 94 octane fuel in my tank, spraying 100% methanol at about 75% of max available. I did not quite hit max timing under extreme to high heat, but I have had zero issues all summer and power has been good. I repeat, I have been running the race program ALL summer. IATs have been OK they did peak around 70 on extreme days. Overall I would say the setup is well within tolerances running methanol. I run 100% methanol because I need the octane. If I just wanted cooling it would be 50/50.
sparta would be cool for a B8 party since there are so many significant B8 cars within a few hrs of it. Also DA is always favourable being near sea level and being in Canada. Finally, it’s reasonably quiet as far as I can tell.
You can also rent it for a VERY fair price (compared to $2000 minimum everywhere else).
can you comment on
- pulley size on the GMG
- pressure readings you’re seeing at redline
- any PBOX testing results you’ve had for 1/4 mile, 0-60, 60-90, 60-130 etc (just for fun…we’re all grown ups here)
I would be in for Sparta, Toronto or Thompson. I know another member lives around the corner from me and he would be in also.
;D
There’s a thread in General Discussion for a meet at the strip. I think we’re still shooting for next Sunday October 18 at TMP.
