Best Gears With A Turbocharger?

BWAL · October 24th, 2007, 03:04 AM

i tried searching.. couldn't find exactly what i was looking for..

what would be the best gear ratio for a single turbocharger? i was thinking 3.55..

EDIT

sorry, its currently auto, but before the turbocharger, i'm planning on doing a 5 speed conversion

TurboLX · October 24th, 2007, 08:02 PM

anything higher then 3.55's will be bad

3.55's is kinda pushing it

SWEET2KSTANG · October 25th, 2007, 03:37 AM

depends on power and set up. a friend of mine had 4.10's in an auto with a s/c and it was great. with an auto you can get away with a steeper gear easy. going to a manual will change that drastically. i have 4.10's and hate them, i am going to a taller slick and probably 3.73'sif i dont get the results that i want. i ran 3.55's for a while, but it will take a lot of power to make the 3.55's work correctly.

you want 4.10's with a turbo or centri, 3.73's with a Twin Screw.

NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!!!

What are you saying!?!?!

Ninjawafers! · October 27th, 2007, 02:42 AM

definitely 3.55 or under for turbo. 3.73 is good for SC. 4.10 is good for N/A autos

Turbos love RPMs...

I think with the 5.0 a set of 3.27's would be perfect...

Depends on the combination, rpm range, etc.

An automatic will hold the boost when you shift. With a manual it will dump the boost between gear changes.

your on crack buddy

TT86 · November 9th, 2007, 04:56 AM

I am runnin 3:73s on my turbo fox, and I break the tires loose in third gear when the boost hits (first and second gear are pointless). Do yourself a favor and get some 3:27s or maybe 3:55s if your not running too much hp. This is (of course) all dependent on what tires and suspension you'll be running. I have full autocross suspension with 17s and G-force TAs.... not so drag friendly... but fun as hell to drive to work every once in a while

mustangmanic · November 12th, 2007, 10:03 PM

omfg!!! 4.10's with any FI would send ur tires to hell!

For any turbo setup, i would stick under 3.55... infact i would just stick with stock gears. once u hit that max boost its gonna drop a load on that drivetrain and if u have a short gear, ur gonna spin no matter what. But with 3.27's u hit that boost, u'll catch trac and just GO!!!!

whtpny · November 13th, 2007, 05:06 PM

don't mean to hijack the thread.. but why should he get something like 3.27s or 3.55s on his car with his turbo? im gonna centri s/c mine but 3.27s are stock and i don't dig em.. is it just different with the 5.0 motors? i was thinking frpp 3.73s or 4.10s in mine..

I explained it... kinda. As soon as you hit that boost, if you have a short gear ratio... ur gonna spin. 4.10's will most def spin like crazy 1st-2nd and probabably some of 3rd, 3.73's will most likely spin like a bitch 1st-2nd (if you have a TC, 3.73's are ideal for a SC). An ideal gear ratio would be a 3.55 for a TC 4.6PI and 3.27's in a 5.0. I say 3.27's in a 5.0 because their tq and hp max is reached at a much lower rpm than a modular engine.

TurboLX · November 13th, 2007, 06:45 PM

you will spin all gears with just about anything higher then 3:55's

Click the link in my sig, this little clip takes place in 4th gear... listen closely at the end and hear what I say in the video.... and that is why you don't get 3:73s with twins

deeeang

wadman · November 17th, 2007, 10:47 AM

Just buy the 4.10s and get some 285 35 - 18 drag radials like I did and freaking blow off the tires in the first three gears. People watching will cheer at you and think your cool. My turbo laughs at my 555r's.

TurboLX · November 17th, 2007, 01:05 PM

lol you will never gain traction with 4:10's
