I just recently purchased the new roush tvs2300 dual belt supercharger for my 2007 Shelby gt350 with automatic transmissionand was curious about how much boost and hp the engine can handle before having to do major engine work and I also purchased a JLT carbon fiber CAI to go along with it.
Thanks for the help!

 

Look in 2005-2009 GT mod forum, the Shelby uses the standard 4.6 3v with just an FRPP CAI IIRC and FRPP X-Pipe IIRC

How much is your kit designed to put out? Less than 500hp should be no problem at the crank and I even think at or just over 500hp at the crank is still not a problem.

Not related to your question, but great suspension on that car (meaning ShelbyGT - IMO best suspension out of the GT - Bullitt - GT500 for those years), if it hasn't already been done, add some good summer tires and have some fun in the twisties!!!!!!!

 

It is able to put out up to 700hp with a pulley swap but it's putting out around 450rwhp 433rwtq as of right now. The next thing I'm doing is installing some upper and lower control arms and when the weather gets better, I'm putting my summer tires back on.

 

2007 GT350?

 

+1

 

Even if he means a Shelby GT...could you get them in an automatic?

 

Yes.

 

Dealer package maybe?

If it is just a dealer package, then it would most likely have the standard 3V 4.6 that all GT's have.. If so, you'll want to keep the whp below the 500 mark and get a GOOD Dyno tune.

 

Yeah the Shelby gt is an added on package it's pretty much a regular mustang gt but with a couple power adders, suspension upgrades, and the Shelby name

 

So do you have a Shelby GT?? As with others, never heard of an '07 Shelby GT350??

 

Kinda like the GT350 that is out now.

 

Yeah pretty much like the one that just came out
