I may be interested as well.

 

Probably not. The GIAC ("Steve's" to those who aren't following along too well) product line includes chips for 91 octane, 93 octane and a "race" chip. The race chip comes with a higher redline, which may be optional--not sure.

If you're interested, Google on GIAC. There are many dealers who have web sites with different levels of information detail.

 

Lots of doubters out there so go to Steve's website: www.911chips.com where his chip and the performance including some dyno information are explained. I think it says something there about how increasing the octane over 91 increases the performance...seems like a logical thing. My thought is that if you have to be oversold on the chip then don't buy it. I'm not saying waste money, but you know the half full/half empty thing. I've owned six Porsche's and put performance chips in two At least I thought the cars felt better and afterall, isn't that what this is all about!! Let's move ahead with the group buy. (not affiliated in any way with any of these companies, just like a faster car)

 

Oops, another Steve confusion.

How about, to avoid confusion, "Steve's chip" means the chip made by Steve (Wong) and the other Steve's chip (sold by Steve) could be called--I dunno--how about "Garrett's chip" to keep the same nomenclature?

 

There's only one "Steve's" chip to me and that is Steve W from Rennsportsystems in Portland, Or.

 

Er, so what is the group buy for Steve Wong or Steve Rennsport?

 

I'll second that.

 

"I think it says something there about how increasing the octane over 91 increases the performance...seems like a logical thing."

Right!

It's amazing what some will believe. But then again, there're those that "buy into"
anything, e.g. the hype about performance chips.

 

man my ENIAC is slow today for some reason??

 

Loren - can you elaborate on your point?

 

There's no technical basis to the statement that using a higher octane grade of fuel will improve
performance for an automotive engine. Just like the ridiculous statement that "custom tuning"
will improve performance for EACH stock engine. But it's statements like these which generally
appear on threads about performance. As is this very common one (a real joke):

"I did a dyno run after installing my new performance chip and assuming an 85% drive train
loss, I'm now getting a 12.5% increase in RWHP based on the Porsche published factory specs
of flywheel HP for my '95 993. And confirms how much better the engine "feels".

 

+1

This is the first time I've heard of Steve Wong's highly-regarded chip mentioned on this board, but to avoid confusion and to set the record straight, in the time that I've been here on the 993 board, "Steve W" refers to Steve Weiner's Rennsport chip.

 

From Loren: "There's no technical basis to the statement that using a higher octane grade of fuel will improve performance for an automotive engine." So Loren: why don't you use, say, 85 or 87 Octane in your car? Colud be engine damage or loss of performance? Who are you kidding?

 

Chris, I think we really need some clarity in this thread.

Can you please clarify exactly who our proposed sources are (i.e. autothority, 911chips.com, Rennsport???).

Also, can you clarify what years can be includes in the GB? On the 911chips.com website, it says '95 993 and '96-98 Euro 993. Can US '96-98 993s join in?

Has Steve Weiner of Rennsport indicated he could provide a GB and, if so, at what price/terms?

Sorry for the basic questions, but there is too much chatter in this thread for me to ascertain what I would really be buying and how.

The proposed Group Buy is

 

"So Loren: why don't you use, say, 85 or 87 Octane in your car?"

I do use 87 octane in one of my cars and increasing my fuel costs by using 91 octane will
yield NO improvement in performance.
