So I am thinking of the following mods to my gts:

Softronic ecu flash
Fabspeed cat bypass
EVO intake.

With these mods how close to 450 HP is possible. If I add the "claimed" HP increases up it looks like I'm close. I'm figuring if that's true I'd spend about 2500 for roughly a 45 HP gain or about 50/HP.

Has anyone done all these mods and has a dynoed to justify manufacturer claims?

How have these mods effected the performance times? Thinking even with this HP the cayenne is such a heavy beast that it would matter very little.

Comments?

 

You'd certainly feel the difference with those mods, but they won't make your GTS significantly faster which, in my book, is OK. With a beast like this it would take quite a bit more horsepower to make it significantly faster, but relatively inexpensive mods like this would give you better throttle response and a bit more sound which would be nice. Of the 3 mods you mention, I'd probably skip the intake if the flash doesn't require it as I suspect it'll add the least and I'm not big on additional intake sound. My $.02...

 

Thanks Jay. I kinda guessed that because of the weight you would need at least another 75 to 100HP to make a difference. You figure the Turbo with 500HP only gives you a second in 0-60 times.

Maybe I'll get like .2 or .3 seconds out of it, which would put me on par with the new GTS of 5.4 0-60. I can handle that.

First mod will be the catbypass, followed by the flash probably.

 

Ferraristyle with those three modifications you will probably push around 435-440HP tops. Include a less restrictive rear exhaust for a few extra ponies but 450HP may be a far reach with bolt on mods. You have to average the projected gains of each individual product but with 405 on tap stock, the ECU, intake, and catbypass pipe will give you close to 30HP.

 

450hp is attainable with a catless system, a tune, and these equal length tubular headers from SuperSprint. The quest for optimal power however becomes exponentially expensive the more power you want!

 

Well just set up an appointment to get the Fabspeed Cat Bypass installed along with the EVMOS intake. Hoping for about 15 or so HP here. Then I'll save some coin for the ECU flash. Can't wait!

 

We achieve 27hp 48lbs tq with only an ECU tune. Contact us for more details.

 

That's a huge claim for a NA car. I like the idea of going to 432 HP. However, I am wondering if you have dyno chats to back this up for the GTS. If you do I'm in and will schedule an appointment tomorrow. But I have to see the "proof in the pudding" first. I looked on your website and don't see a tunechart for a GTS.

 

Unfortunately, as of the moment, we do not have one. The next time a GTS comes in, we'll make sure to dyno it.

Thank you

 

These are very cool. Most sound killer too!

 

Save your $$$$ it's a NA car by the end of the day.

 

thats a lot of money.
