GT40P's or Twisted Wedge?

Unit 5302 · 07-17-2002, 06:53 PM

89 Cobra LX I'm going to do this ONE more time. People wonder why I'm hardly ever on this site anymore? You can't figure out how to get your engine to run worth a damn so nobody can have a good running engine combo. I see.

Let's get things straight. In that discussion we were talking about the GT-40 irons.

The GT-40 iron "Cobra" heads are NOT the GT-40P heads. The bone stock Cobra's dyno about 220rwhp, which is 260hp. A bolt on Cobra with a good computer will make better than 300hp with inferior heads. Why do you think the GT-40P combo is weaker than the GT-40 iron combo?

Central coast rates their GT-40P combo at 320hp. The Stage 2 GT-40P combo from XFM is rated at 325+hp.

I don't have time to search the web all day for you. There are a couple links, and a couple references. Like I stated before, if you can't get 320hp out of a well setup GT-40P combo, you need sombody else to put together an engine for you. The race guys are trapping 120mph N/A on bone stock GT-40P castings. They are dynoing over 340rwhp. A quick mill of the heads will get you 10.0:1 compression, and their greater compression isn't giving them 100hp.
