So I have an 05 GT which I have spent a small fortune on. It's away for winter but I have been adding stuff to it. I have gotten everything from American Muscle and using their tunes. They don't have one for the cams but seems to run fine anyways. I will be taking it in for a dyno tune in the spring. Any rough guesses what I might get gain wise?

Here are the mods.

JLT Cold air intake
BBK 62mm Throttle body
C&L Intake manifold
Steeda Underdrive pulleys
FRPP Hot rod cams
BBK Shorty headers
Magnaflow X-pipe with high flow cats
MBRP Axle backs
4:10 gears (i know they won't affect hp)
93 Tune

Also if you can think of any other bolt ons I please post your suggestions.

 

Aluminum driveshaft. I just ordered one yesterday lol

I'm not familiar on the FRPP Cam gains, you should be somewhere in the mid 300's once the tune is dialed in.

 

At the wheel? Ya I have been looking at drive shafts. Any recommendations?

 

Yes, at the tire.

I decided to try that one, we shall see when I get it.

 

I would just make sure you do all of your research on the TB & intake. You may not see much if any of a gains on a N/A engine that is running stock stroke/bore.

 

I'm assuming your car has a manual trans, so it should put down around 310-315 rwhp, IMO.

 

I say around 315. My friends car made 295 RWHP with just UDP and Intake.

 

Me too, before my O/R H. 295hp

Looking forward for the numbers, I'm gonna say 325 as my official guess lol

 

+1

I do not trust vendor HP claims. Too easy to just tweak another 20-40 hp from a dyno and report it as being a result of their product.

 

Mustang dyno yes, dynojet no.

 

You guys are nuts! 310-315? Maybe without it tuned for the cams. With it tuned right it should be 325+rwhp SAE.

I'd also HIGHLY suggest getting a tune for all that stuff from a tuner such as brooksspeed. It will make a big difference in power and I would venture driveability, over the american muscle tune. Especially if the AM tune isn't setup for the cams.

I would also suggest bringing your handheld tuner and checking your air/fuel while on the dyno. If need be I would use your tuner while on the dyno to adjust the a/f to as close to 12.5 at wot as you can get it.

 

You're speaking Japanese to me when talk air fuel ratio. I am taking it to Dasilva Racing locally for a dyno tune. They come highly recommended.

 

Most dyno read outs give 3 variables. HP, TQ, and air/fuel ratio. They will know what to do at dasilva racing. Just bring your handheld tuner and let them know you brought it, so they can make any needed adjustments while on the dyno.

 

I'm guessing a little higher, about 330hp...
