Tim,

Great news on the new kit! With Safety and Reliability being such big concerns with these ventures, I for one appreciate all the testing and development you've done. Of course we love the power! As I'm sure it is with all the different SC kits out there - it just feels right having this kind of power in the 928. Do I want more = Yes! Do I have enough now = most likely, but the desire for more is always there...

Sooooo, what's involved in the upgrade for us Stage II owners - injectors, new Vortech pulley, chips? Any idea on the cost?


Thanks,
Pete Whelan
1988 928S4, Murph SC'd

 

Awesome, Tim! Great work!

So, does the price include a G-suit?

 

Tim
Another ???? will it work on crappy CA 91 octane gas?

 

This is just neat...
Kind-of makes me look at mine differantly now.
So much potential just a bolt-on away.

I agree with Hacker. I don't need anything special, just a smaller pulley and some tuning... oh and probably 42# injectors. Also let's not forget that the TS is a bit more efficient CS , so I should be able to achieve 500RWHP at or slightly below 10psi. I've already talked to DR about achieving this goal.

 

Tim:

That is an awesome acheivement, congratulations. It is very impressive to me how the upper limit continues to be explored and surpassed. These vehicles really are very robust.

. . . waiting for the video

I thought TS was slightly LESS efficient than a CS....only about 10% though.... Something like this: 50% roots, 65% TS & 75% CS.....???

 

Iceman / Andrew - knock it off!!










becasue we all know which one is really better

 

Brian-
I made 441RWHP at about 8psi. That roughly 20RWHP/psi. (I'm using 15% loss)

Murph achieved 511RWHP at about 12psi. Using 18% loss, that's an improvement of 214 RWHP or roughly 18RWHP/psi.

That means the TS is about 10% more efficient in this real world case. However, in reality, it's not that big of a difference... just a different path to the same destination!

 

Turbos... Que the talking monkey!

 

I think the GT gets a better HP per PSI of boost gain then the S4 with the same system. I remember Andy telling me that his S4 systems made 15HP per PSI and the same system on a GT making 20-25 HP per PSI of boost.

 

damn .. its time to do some serious saving to make this happen ... 500rwhp must be amazing

 

I just changed my pulley to 8PSI. I wonder what kind of power I am getting.
It feels fast though... BBWWWWWWWAAAAAAAAAAAAAAA...

 

Andrew, wouldn't it be more accurate at your 300 to 441 (stock GT to TS @ 15%), vs Murph's 265 to 511 (stock S4 to CS @ 18%)?

That'd be 141 increase @ 8psi for 17.6/psi and 246 increase @ 12psi for 20.5/psi --> Murph's is more efficient

Looking forward to your results after tuning though and a comparison with the shape of your <TS> power curve

Congratulations Murph !!
