maybe forged pistons and rods.. lower compression.. who knows!?

seems like they upped the boost on the gtp. or maybe a better cam.

that would be nice if the gtp came with rear wheel drive and a centrifugal supercharging unit..instead of roots type.<hr></blockquote>

Tyler, please refrain from posting in Advanced Tech unless you actually know the answer to a question.

they wanted to use the caddy tranny, to handle more power, but it was too big for the platform. They also has to keep the torque down so that the tranny's would last.

I thought we already had a returnless fuel system???? I did read a few days ago about GM's future plans for the V6. It'll start in the new Caddy's and then make its way to others.. It entitled a DOHC engine, and some pretty cool add-ins. Alot was based on the LS1 design, but incorporating some "newer" technology too. Pretty cool, said they would stock push about 275hp...<hr></blockquote>
there's no way the 3800 will go into a caddy. the engine you're talking about is completely different.

according to car and driver one of the main reasons for the bumping up in HP is the blower is supposed to be more efficient.. (ie less parasitic loss)

less power to spin the blower = more power to the ground

Read my post. Did I in any way say the 3800 would be in a caddy? I mentioned "GM's future plans for the V6". Thanks.

there is the red-headed step child of cadilac, the cinomin, I mean cimeron. I think it had a 4cyl, but not sure.

[navyblue2000]

first off, the 3.4L is no longer the L32...it's got improved intake/head designs...so yes, it DOES have a new designation. (I don't remember the number, but the option code for the 3.4L in impalas is NOT L32. So the series 3 COULD be an L26.
Keep in mind too, GM did produce an LT-1 and an LS-6 long ago. now it's LT1 and LS6. nice case of ambiguity there too...

HEY! i had me a cimarron...or cavillac if you wanna call it that. could get a 2.5 or 2.8

The High-Value V-6s of 3.1 and 3.4-liters will be bumped to 3.5-liter V-6s in '04. We'll see this new 3.5 on the '04 Malibu. Then a year later in an updated Rendezvous, we'll see this engine as a 3.9-liter High Value V-6, the 3.5 will also be available.

A new High Feature V-6 is also going to debut in '04, in the Caddy CTS. It will be 3.6-liters pumping out 255 hp. Also, a 3.2-liter High Feature V6 will come out to replace the current 3.2 based off the 3.0 V6. The CTS-V will get a 5.7 v8 pushing 400hp!!!

A 7.5 V12 has got the green light too. Most likely going into the Escalade series, along with a new big rear drive sedan.

A roots supercharger won't make any less power than a centrifugal supercharger. In fact, ultimately a Roots blower will make more power, than any centrifugal supercharger, or Turbocharger for that matter.

Returnless fuel system: In a return-style fuel system, the fuel pump sends gas to the engine, uses some of it, and sends the rest back to the gas tank (not exactly efficent). In a returnless setup, all the gas that's sent to the engine is used. It's lighter, uses less parts, and gets better mileage. Simple as that.

Close-couple converter: The exhaust manifold and the cat are made into one big unit, instead of the manifold and then the cat downstream, such as in a fourth-gen f-car.

Yeah, these ARE improvments (GM has been doing that for 40 years now), but it begs the question: where's the EXTRA FREAKIN' HORSEPOWER!!!

Right. I have always heard we have returnless. Is that true?

sounds sort-of like the manifolds in the old thunderbirds & linolns. they had a convertor coming off of each manifold.

The new GTP 3800 SeriesIII engine will be designated as the L32.

The additional horsepower will be gained mostly by a more efficient Eaton M90 series 5 blower and slightly larger throttle body. The new GTP is also a drive by wire setup, which means the throttle will be controlled by a computer versus the pedal being attached to the throttle body. The reason most people think this was switched is because the engine is making more torque and with this setup the computer can control how much throttle the car is actually seeing so too much torque isn't hitting the weak nut tranny all at once.

dang john, i thought you actually had cut/pasted that paragraph...until the last sentence [img]graemlins/rofl.gif[/img] [img]graemlins/rofl.gif[/img]

Yeah, I got mad writing skills.....but only for like 3 sentences then it goes all to hell. I'm just trying to get you boys straightened out on the facts.
