No that is incorrect, the air filter and intake go into the supercharger before they go through the intercooler and then through the dual throttlebodies. If you watch the video threads I posted early you will see what I am talking about.

I believe I am the only one running LTHs currently, I believe a few have HFC.

What's the performance difference between the two?

Looking at posted dynos, it looks like LTH's, which eliminate the cat, tend to make about 2-3% more power from baseline than test pipes.

That translates into 6 - 8 more whp than TP's alone... I could be a bit off, but I think that's about right.

Wait, I thought people were losing a bit of power with LTHs on SC'ed Z?

From my understanding people are losing power with the LTHs. If they were gaining power people would not be holding back dyno info. I also remember shumby was losing power and thats why he went back to the stock ones. Maybe I am confused but I am pretty sure of it.

Shumby, any upates one what exactly failed in the trans and why?

Jordo! · 11-12-2010, 04:52 PM

Oh, sorry -- that was dumb of me -- was basing that on N/A dynos I have looked at.

That said, I'm surprised that people are losing power with a blower and headers... that doesn't quite make sense.

Even if you are making less boost, given the same S/C output, boost is just a measure of restriction, and better flow generally means more power. Tune issue maybe?

shumby · 11-12-2010, 04:57 PM

^^^ no not yet as it is still on the car. Should be gettign chsnged out this week or next week. then it will be sent to Sam at GTM and we will know more then. I'll keep you all posted but it will be a long time.
