Get an o/r midpipe to open the exhaust more and retune and you should gain a bit

Put yourself in a possition to not want to rebuy parts and buy the best the first time around. Accufab and its plenum are king of the hill. Also I would like to note that the TB/plenum mod is worth a noticable amount of power on these cars as the induction side of the N/A modular engines are starved of air, another reason why the modular engines respond so well to boosting. P.S. If you do the plenum be gentle with the intake bolts when you retighten them, the bolt heads can snap off. If you have a torque wrench I recommend using 2lbs less torque than manufacturer specs.

Accufab is king, but its also really expensive. SR is a good brand too and its a fair price. SR is the tb/plenum set up I will be using.

I've been thinking hard on getting one. I found accufab 75mm TB and Plenum for $200 on CL. I got it narrowed down to that or Bama bank 4 chip. TB and Plenum is just to good of a deal, I think.

RUNNWLD,

You can certainly expect to feel a power gain from an SR Plenum and TB. Most of the power increase will be throughout the power band too. Which, is the best place to increase power, IMO. More power lower in the power band will be noticeable while daily driving, opposed to peak HP is only noticed when full throttle!

As mentioned above, an O/R mid-pipe is a good option too! Both will suffice with more HP/TQ!

Reguardless of brand the TB/plenum on these 2v motors are a weak point in performance and you will notice a difference no matter what brand you go with.

However like I said in another post, 2-3hp spread across 10-15 mods is a big difference in performance which is why I recommend going for the best parts you can find the first time around. On my builds when im ready for a mod and cant afford the best performer for that type of part then I pick another mod that I can afford the best performing part.

This principle of modding will not only help you have better performance over all but in the end game can save you money by not buying the same type of part twice. Also to me its discouraging to see someone have the same exact mods you do but they have more power or better performance.

If I had your car with those mods my next step would be the Accufab TB/plenum I already mentioned, a FRPP aluminum drive shaft, electric water pump, gears, lighter wheels and or stickier tires depending on how much money I had in my pocket.

I'd do gears with that money. Nice short gears and a quality shifter (if you don't already have one), yeah, it really does make that much of a difference.

It may not add any power, but steeper gearing has a HUGE effect on the performance. I wish I had done my 4.10s years ago instead of fiddling around with tunes and bolt-one trying to make that little bit more power.
If you did upper intakes and everything, you'd need a tuner to really see the benefits. That's another $300-$400 on top of the TB/plenum.

Yeah I have the tuner so would you guys say gears really make that big of a difference? And how much would gears be and to have them installed?

Performance gain is dependant on gear choice. 2.73-4.88. The 4.10s and 3.73s are the most popular choice for N/A street cars. The 3.73s have less of a fuel consumption than the 4.10s. However the 4.10s will give you better acceleration than the 3.73s with use of a stickier tire. Gears are the single largest performance improvement for a bolt on car without use of a power adder. Gear choice down the road can become more complicated as you decide to use a power adder or an aftermarket cam. I recommend 3.73s for your application and recommend having a profesional mechanic install them if your not mechanically inclined. The cost of gears plus installation usually runs around $500 in my side of the world.

I can beat dad's moderately modded 07 GT (shaker intake, TB/plenum, full exhaust, Steeda sport suspension + Tokico struts, Hurst short throw, tune, and 3.55) with my almost stock GT (just a ported TB...according to my previous owner at least, H&R SuperSports, adjustable panhard for wheel hop, 4.10s, and MGW). Sure, he pulls on me after a while, but I grab and hold a solid half-car to car-length for a quarter or so both from a dig and from a roll. The roll always goes much better because I get to sit smack in the middle of my powerband on each shift and run it all the way through.
I come pretty damn close to beating an R/T challenger every time we run too, but I think he's a sh1tty driver.

Just go ahead and get 75mm tb/p I got mine and the throttle is so sensitive and a notice in power.

The bbk unit is big and well suited for large boost with use of an aluminum lower intake from say PP.

This is gonna be long, but it's really good information.
Motive took over the FRPP gear manufacturing. Motive is known for making poor quality gears that whine no matter what you do.

Lifted from a thread on ModularFords.com with FRPP/Motive discussion and reliable sources (mechanics with personal experience with both companies and even a Ford manager).
Quote:
For what it's worth, the date which motive began manufacturing the 4.10 gearset for Ford was 11/05. My installer, who is a Ford mechanic, does 50-60 gear sets a year. I have driven in many cars the year before in which he has done the gear installs and have never heard a set of his gears whine. I had it done by him late March/early April as soon as the car came oit of storage. These were the M4209G410M instead of the M4209G410A

As others have stated they are made for FRPP by Motive and have a backcut on the ring gear.

After installing them we went for a road test and the whine on decell was insane.
To make a long story short he setup the gears 3 times and didn't charge me any more than if he did it once but the whine was still there.

We happened to pull a set of older FRPP 4.10's out of my friends 03 GT 1/4 mile car which had about 50 runs on them and threw them in and no more whine.
Quote:
You can get the original FRPP gears again they just started releasing them again unfortunatley they are more expensive. If you are buying them and want the gears from Ford and not Motive make sure the number is M-4209-G410A instead of M-4209-G410M.
Quote:
Hey guys my name is Rick I am the Mgr of Downs Ford Motorsport. The M onthe end of the part number means they werebuilt by Motive gear. I have also had issues with whine noise's. What I been doing is having anyone who purchase's the gears with M at the end of the number go onto Motive gear site and download the motive gear install instructions they seam to differ from the Ford set up a little which I have found makes the difference so their is no Whine from the rear. Any question feel free to call me at 1-732-349-2240 ext 958 ask for Rick

4:10s for auto and 3.73s for manual.

If I buy the gears do I need the gears package with all sorts of stuff from am or just the gears I'm probably having someone do it so it's done right.

So if I just buy the package will I just take all that stuff to the place that installs the gears and they will do it all?
