The biggest CAIs are Steeda and C&L Racer (actually there is another but I forget the name). The Steeda is also bigger than the C&L Street. I was going to switch to C&L Racer but I've decided on the Steeda since it's not much smaller (5mm) and you can get a cool looking carbon fiber elbow with it (which also helps to keep the air cooler than the metal designs). Plus its blue which matches my car's color.

That with a tune will give a very nice HP boost (30+).

The Steeda under drive pully (UDP) is a good option (unless you have a s/c) as well as headers.

The throttle body spacer is a waste of money. It doesn't do anything. Delete plates are also not worth it as they do very little if anything on these cars.

 

C&L intake with a tune, headers, and a set of UDP's. Mufflers won't free up much power.

 

My current plan for mods are:

1) Steeda CAI + Brenspeed tune (done) $620
2) Side Window Louvers & shorty antenna (done) $200
3) 3.73 Gears (if manual I would get 4.10s) aprox. $400-500 w/install
4) 1 piece aluminum driveshaft (Spydershaft specifically) $550 (will install myself)
5) Lower Control Arms & Panhard Bar Less than $400
6) Long Tube Headers (Kooks from brenspeed, free retune) $1300 (might install myself)
7) Underdrive Pulleys (unless I S/c) $200.. unless I buy used, will install myself


8) In a couple of years, saleen stage 2 from brenspeed + tires and maybe wider wheels $6000+gas for the trip

with these (1-7)mods the numbers are all over the place for rwhp.. most seem to be in the 330rwhp and 350rwtq some as high as 340/360.. stock is usually about 265rwhp and 280rwtq so thats about a gain of 65 to the wheels. you can throw in a camshaft there.. i believe that is about $650 for the cams and install is pricy.. like $1000+? and will gain you a further 20hp on average.. (some will add like 30hp under the curve)

 

intake/tune,full exhaust,delete plates,under drive pulleys,gears(3.73/4.10s),clutch (torque converter if auto) would be a nice bolt on car and possibly run mid-high 12s I would say.

 

My plan for my next car (07 Grabber Orange Gt manual)

1. CAI & tune
2. Gears, im thinking 4.10's
3. Cams

Then tear everythin off andog F.I.

 

I agree completely - that's all we've done mechanically on mine - and we've upped the hp roughly 90hp - the tune provided the most with 70hp

 

I've never heard of anyone getting 90 hp with tune/cai/exhaust.. even with long tube headers off road pipe and cai and a tune for all of that most people gain a total of 40-45rwhp do you have some dyno sheets to backup these claims?

 

Throttle body spacers are useless.

And if you're considering a supercharger, unless you're getting the TVS2300 don't get a Roush supercharger. Get something like a Whipple, Saleen, or Kenne Bell instead.

 

Anything in this thread is modest and good seat of the pants feel IMO..... https://mustangforums.com/m_5363686/tm.htm

 

Correct, never heard of 90 with those mods.
A friend got 331RWHP on his 07 manualwith a C&L Intake, Bama Dyno Tune, SteedaUDP, ARLT Headers, Stage 2 Comp Cams NSR. Also has 4.10 gears. HisBase line was 265..

My Car baselined at 260 (5R55S Auto) I have a JLT II CAI, Bamachips Dyno Tune,Under Drive Pulleys, Spyder DS, CMDP, JBA Longtubes, JBA Catted H Pipe, and I Dynoed just under 300 RWHP, I also have 4.10 gears, CHE LCA but run 12.41 @109.35 in the 1/4 mile. So don't be to caught up in numbers
