I have considered that and when I reach that point I may decide to stop. But I want to put gt350 rocker stripes on it and I think I would have a hard time doing that if I knew it didn't live up to that at the rear wheels.

Tknman - the GT350 doesnt put down 350 to the wheels, so it's a misnomer. However, I can understand why you want that.

The Roush M90 supercharger is a very reliable FI system which will definitely get your mark in one swoop. Many of the FI folks (myself included) went that route because of concerns regarding warranty and reliability. The Roush M90 has proven itself a winner time and again in that regard.

As for the other mods, I think 350 to the wheels is going to be a stretch because of parasitic loss, etc...Perhaps there are guys that have been able to pull that off here but I dont recall seeing any. You could however get to 350 at the crank with bolt ons.

The problem with FI is that you have a very large one time expense but with bolt ons and mods like hot rod cams, etc...you can spread that cost out over time.

One lesson that many of us have learned is that once you start modifying, its very hard to stop. However, totally worth it Welcome to the family and advice is always free. Just don't ask these guys to help you move a couch this weekend! lol

I just saw your question about FRPP...I have found that to be a mixed bag. For example, if you decide to do a gear swap there's no doubt that FRPP gears are what you want. Motivo and some of the others have had mixed results.

But then you take the CAI route and the Ford one looks decent and can come with a tuner, but it seems to me your relegated to that with little room for expansion which becomes a problem in the future. The best place to start if you decide not to do FI is pickup a good CAI and tuner combo from someone like American Muscle or Brenspeed. Both have good reputations and I've been happy every time with them both over the years. You can also leverage your forum membership to get discounts from some vendors, so look for those too.

Once you have a good foundation with a tuner you can then order parts like cams, contact the vendor you bought them from and get tunes for free on that car forever. You call or email and say you need a new tune and here's the specs and you've got a semi-custom tune.

Once you've got the car solid enough and built up, then consider a dyno tune. Every car does run a little differently, but a dyno tune will be built specifically for your car by the tuner and get you the max output possible.

350 RWHP is definitely achievable NA. Some cars don't respond as well as others to mods though. .This guy on S197forum is making 353 RWHP/325RWTQ with these mods:

-Kooks Headers w/ Catted X Pipe
-FRPP Hot Rod Cams
-FRPP Intake Manifold
-FRPP 62mm Throttlebody
-JLT Series 3 110mm CAI


If you wanted to make absolutely sure, get a VSR or an SPR cam

350 rwhp with cams, LT's, intake, tb and pulleys. Easy..

to the op. The original gt350 was 271 GROSS hp at the flywheel. Stock you are way past that with your 07.

Won't a good dyno tune have the most to say in how close he gets to - or beyond - 350hp n/a?

It will make a big difference, yes.
