What's your Biggest Bang for your Buck Mod ???

I am never going to take my car to the track, so would you guys recommend 3.73's or 4.10's ? The car is a 5 speed GT and is not my daily driver. I can't see why I would need 4.10's under these circumstances. It currently has 3.31's.
 
CAI, tune, gears, and drag radials...

MANY other mods out there, but besides nitrous or FI, these 4 will be the only ones your ass dyno will really feel; and they will yield lower et's more than a couple tenths.

Once there, make sure you are set on your future

EXAMPLE:

If you KNOW you are going with sc or turbo, do NOT spend $$$ on exhaust unless you are positive it works to your favor i.e. Long tubes and a high flow system will usually yield 2lbs of boost lower. FI needs sum back pressure.... UNLESS you are going with huge boost. Now, thats a whole new story...
Fi needs some back pressure? Lower PSI doesn't always mean lower power, PSI is a measure of pressure/resistance. Same set up + mods that make slightly less PSI due to increased flow means more air is moving through than before, correct?

Stock cats are a restiction with FI..I have an O/R x-pipe with Magnapacks custom tuned with the Vortech..it breaths better and gets through the rpm's quicker which is what you want with a centrify..The quicker the air comes out the quicker you can put more in is more power IMO...

never going to race? Sad... :nonono:


if i were you id keep the 3:31's then or go to 3:55's at the most 373s but most likely not esp if u dont plan on like ever getting on it often.

If you dont plan on racing at all period,ever. dont bother getting 4:10's.

Sad ? Not really. I enjoy the car as it is and want to keep it for a long time. As I said it isn't my daily driver but I do like to get on it occasionally, within the law of course, and wondered if moving up to 3:73's would be worthwhile from 3:31's. I really didn't think it would be worth it for highway driving to go to 4:10's if I am not considering taking it to the track ever.

Thanks for answering my question !

It would be worth moving from 3:31's to 3:73's. It would be a much noticeable gain/difference.


Having it not be your daily driver is just a better reason to RACE it :) lol

My mustang is my daily driver currently and track bracket car for fun, its too addictive.

I also want to keep mine as long as possible while being my DD(since Nov '06). It now has just over 51K miles(8.7 when new Aug 29, 06)and the 4.10s have been in there since about 13K miles and I don't regret it at all. In fact, when it is not my DD, I wouldn't mind putting 4.30s in it even if it is just for joy riding around and maybe twice a year to the track. Granted there will be a good increase from 3.31 to 3.73, but from 3.73 to 4.10 there won't be that much difference as far as MPGs and RPMs go. Not trying to convince you 4.10 will be better, just letting you know how the 4.10s can be driven daily with no problems.

Strange as it may seem, I am not really interested in racing it. I enjoy what I get out of it without going to the track. I might change to 3:73's and see how it goes. I just bought a Hurst billet shifter for it, so I might go for the gears next once I get some more money together.

Thanks John, I was looking forward to meeting you at the Kip Killmon open day last Sunday but apparently you were working. I'll catch up with you at one of the meets out at Dulles soon.
 
I would think 4.10s in an automatic (cough) would be a lot different than if you had to shift your own gears....in a daily driver.

I talked to a guy from Ford Racing last night (on Woodward Ave. :nice:)....he said for me to go from 3.55s to 3.73s would be a noticeable jump in the way the car drives. I know nothing about ratios and have never changed them, but would this change register on the butt dyno?
