Fellas,

I'm very close to pulling the trigger on a supercharger for my 95'. However, I like many of you, want something that has been proven to work, given the cost of this mod. For that reason, I think TPC has done the most extensive R&D on their kit thus far and will likely be the kit I purchase given the availability of a newly introduced intercooler. I have corresponded with TPC in hopes of getting a little more info about the kit as it pertains to my particular application. If anyone is interested, please post here. Thanks.

Hello Jeff,

Thanks for writing us. Your '95 993 should put down 220RWHP on a
Dynojet chassis dyno. Our TPC Supercharger will take it up to
310RWHP/289RWTQ. With the TPC intercooler is 355RWHP/333RWTQ!

The intercooler will fit with stock decklid. It is a tight fit but it
does fit. The inside of the decklid must be trimed.

The current price of the TPC 993 Supercharger is $6595. The intercooler
kit is $3395.

For an order of 5 Supercharger kits, I can give you 10% off. It must be
5 kits(no less), pre-paid by cashier's check, and the price does not
include shipping.

$3395 for the intercooler? That seems WAY out of touch with reality. Outrageous, really. That pretty much kills the idea of a TPC supercharger in my mind, unless I get a custom fab'd IC. Didn't somebody just get a custom fab IC a few months back for about $1000?

Just how much boost to you plan to deliver to get 355 rwhp?

mr_bock

TPC's SC is usually set for 4 to 5 psi with out an intercooler. I don't think they boost pressure any more with the intercooler. The water/air intercooler does a fine job in keeping the air charge cool and there lies the added power. It does add complexity and cost. I am not running an intercooler and have 322 rwhp. I also spent some time porting and smoothing welds out that may have helped.

IN IC for that much is insane. Hell ,the kit is insanely priced as well. The only thing you need from that kit is the new intake plenum, everything else can be purchased for sooo much cheaper, but since they have the monopoly on this, that is the reason they can charge these insane prices.

So I guess no one else wants one, shucks! Guess I'll have to wait a little while. I don't plan on getting an intercooler anyhow. Running at 4-5 psi of boost is not high enough to warrant intercooling on a street car in my opinion. Then again, I have no idea how hot the charge air will get in our application compared to ambient temps. Maybe someone with an SC can chime in. 322rwhp and 280rwtq is plenty for the street anyhow, more than enough to smoke your tires.

I'd be in, but I'm waiting to see what Stephen comes up with...

It took TPC 2 years to develop theirs. 6 weeks to iron out bugs etc,etc is mighty optimistic. Not saying it can't be done, we'll see.

JohnJL

I hear you...but I will wait to hear what expectations Stephen sets for delivery and what the basic design will be...I've heard good things about him and will give him the benefit of the doubt for a few weeks to figure out price/design/lead times.

10% isn't much of a discount. Do the TPC guys yet know of their impending competition? Maybe they'd be inclined to revise their pricing...

Strange how the total sc/ic kit comes to $9,990. "For less than $10,000, you, too, can add blah blah blah...! It's amazing -- it's incredible!"

KASH '95 993

$10K, wow...for another $2K, I could have a twin turbo kit with intercooler installed.

4-5psi on the eaton m90 is not enough to justify in buying an intercooler. I have an Eaton m62 which is a smaller blower than the m90 and i run 12-13psi all day non-intercooled on my nissan frontier. Stock was 6-7psi but i changed the pulley to get 12-13psi. My other truck that i added a Vortech supercharger does 10psi non-intercooled and the intake temp gets 200deg while ambient temp is 80deg. Just to give you an idea on how hot compressed air can get. and not to mention the eaton blowers will heat up a little more that the vortech blower. With that said, as long as you have the fuel running on the rich side, you should be fine running 4-5psi. But keep in mind, our n/a 993's have a higher compression. Thats something i would worry about instead.

Hello everyone,

I thought I would share some data that I have captured from my TPC'd 993 tip. I used a gtechpro and downloaded some data from their webpage of other cars using the gtechpro. I decided to compare a 450hp 996tt and a M3 against my numbers.

I thought you might be interested that I achieved a 12.6s 1/4. This is running a 2.6" pulley which makes about 9lb at 6200rpm where the peak hp is. I also run 50:50 methanol to cool the charge in loe of an intercooler. Car makes about 310 rwhp.

Now I have had mine for 2 years now and done about 35k miles. Would I do it again, without a doubt.

Anyway heres a pdf of the runs.

Cheers, Mark.

Hey Mark, that's very interesting! How accurate are those gtech's? I was thinking of getting one too. 12.6 ET in 1/4 mile? For a 3300 lbs car you would need a little more that 310rwhp. I am not doubting you at all. I am certian the gtech said that. My friend's camaro with a 2.1 60' and 320rwhp, we would only get low 13's and mind you he's a very good racer for 1/4 mile.

Shant - you are right that you might not need an intercooler for engine protection on some setups. However, an intercooler will ALWAYS provide more power to the engine because you are feeding more O2 into the cylinders. You will find that if you can reduce the air temp substantially it will give you more power than increasing the boost 1-2 psi.

I use an aftercooler, but I am also pumping 6 - 7 lbs of boost in a static 11.3:1 engine.
