Who will win, stock for stock?

 

It really depends on the driver and weather. The GTP's or Regal GS's will average 14.7-15.1 through the quarter. On the bottom end I'd say the GTP is faster because of the 280 ft.lb. but higher up at highway speeds I'd give the edge to the type-s. That being said however, the forced induction engines respond VERY well to colder temperatures. Up in Canada several GTP's have run in the area of 14.3-14.4 stock just because it was like 30 degrees out. Also an $80 3.4" pulley and a $200 cai will put a stock gtp upwards of 270-275 hp and over 300 ft. lb. of torque. This will put them close to 14.0's with a good launch.

Weather? They are both FWD, and have traction control? Driver? They are both automatic. I gues you are saying its close and can go either way.

So are 0-60 and 1/4 mile about the same? Will headers give a very big advantage over the GTP? A budy is getting a 99 red 4dr GTP.

I think these are the two fastest 4dr automatic cars on this side of 35k.

 

has anyone here raced one?

 

Wow, thanks for the info, so its really a close call. I was hoping 1 car lenght would be easy with 20 more HP The tranny is week on those cars, and I didn't like the interior, else I would have one. 03 is supposed to be a new car I heard?

 

Actually the tranny isn't weak at all. Usually the only 3.8L's that start developing problems are due to extensive modifications. These are running well into the 13's and are probably putting out in the neighborhood on 350 HP and at least that much torque. That's simply too much power for any factory fwd auto to handle. However, SLP now offers an upgraded tranny with more aggresive gearing which is rated up to 450HP - it's $3600... a little too pricey for me. At the auto shows last year GM unveiled the Grand Prix G8 - this had the 350HP motor from the new Vette as well as a 6 speed manual with all wheel drive. Unfortunately, it will never see the light of day. GM needs to get on the ball and start producing some of these concepts because they are starting to lose a lot of people to the imports such as the TL type-s.

They lost me.

Though, I put that car (1997 GTP coupe) through 216,000 miles of hell and it held up pretty well. Didn't start giving me serious problems until after 200,000 miles. Although the tranny did give me trouble at around 100,000.

I liked the Grand Prix a lot, but this time around I wanted something with a more luxurious interior. That's the GP's biggest weakness, IMO. The interior is made from the cheapest, ugliest plastic that money can buy. I had two A/C knobs just break right off in my hand. The TL-S is great and fast and I'm truly loving this car; it's exactly what I wanted. But I will always fondly remember the kick in the pants from the GTP supercharger on a cold morning.

Hey Gold, I'm a GM guy, but not for long if they don't shape up. I like to keep an import and a domestic at least. For all the other performance GM cars, the GTP tranny is week when you compare. I have a Vette, had several comaro's, and an older TPI third Gen IROC 350 with the 700R4 Tranny (now that a great tranny).

GM makes some of the best automatics that don't loose much HP. If you look at perfromance numbers from the auto and stick GM cars, not a huge difference, thats another story for imports. GM autos shift well, however the GTP is weak. Reason being is that TQ is alread 280 stock on the GTP, however max cap is rated just at or slightly under 300lbs/ft if you look up the tranny the Grand Prix uses. With the pully, CAI your already asking for failure. Stock you might be ok, but I've seen some of those fail under hard use also in GTPs though far less common on the standard Grand prix.

Other GM cars however (Camaro, Trans Am, Corvette...) can and do take extensive mods and HP increases and hard use with no tranny problems. The maximum lbs/ft rating is not so close to the stock output of the car as with the GTP. When they update the GTP (too many years without one now, its in need of one) they need to give it a stronger tranny, and better seats. I also hope they get a new engine as almost everything GM has a v6 in is the old 3800 though its a tried and true solid work horse. An engine of that size, with a SC should make more then, and can make more then 240HP if that tranny could hack it. I think this is one reason they kept HP the same all these years and only added a little more tq., till a new trany comes.

 

The Buick Regal GSE has 16" wheels, as well as the GTP. What were you thinking Pete? You know how big those wheels are. No doubt though, 17's would make all the difference in the world with some good rubber. The Goodyear tires this car comes with are crap. They are purely all-weather cruising tires.

In my mind, after driving both the TLS and GTP/GSE quite a bit at a stock level are just about identical in pure straight line speed and acceleration. There are too many factors which come into play to say which is faster. Pete forgot to mention his TLS has been beaten by my GSE with two people in it to his one in the TLS. That was when he had around 500-1000 miles on the engine.

 

How much did you beat him by Would be great if comptech made a super charger for the type S

 

Comptech is coming out with a Supercharger package eventually for the TL-S. They have one for the S2000, the S Types are next and then the Accord V6.

 

That day, I think he was beaten by about one car length.

 

where can we read about this super charger?
