2.93 vs. 2.76

[jm@ReischePerf]

No not ported yet, but planning on it, thanks.

I would port if first and then add the lower at the same time. I just don't think all the heat generated by an unported combo setup is a good idea.

wheres the 2.80 option?

 

[webleedorange61]

Is a 2.76 pulley a bad idea on a cobra with just JLT RAI and borla stingers? i want to keep a stock look untill i go Whipple.

 

[LS1_KILLA]

lol... well guys.. i went 2.76 ... but like everyone said.. i just want more.. so I've decided to buy a whipple

 

[Tractionless1]

I'd really like to see your dyno sheet with the mods. you have listed making that HP/TQ.

2.93 4lb lower sweet combo

+1

 

[04cobra13]

just do the 2.76, or else you will just always wonder what she would have made with it, which would suck,,,

 

[c6zhombre]

I see the vote is 130 for the 2.76 and 45 for the 2.93

now I'm thinking the next poll needs to be, for the owners that went straight to the 2.76, was a maf adjustment needed? how many had it tuned in warm/humid weather and never bothered to recheck it for big, cold air dome with low humidity and high baramoter? I bet these cars can make 30-40 actual hp/tq difference just from seasonal weather changes.. :shrug:

2.76 that way you can slap a 4lb lower on later and have a beast combo. My car when i had just a 2.76 would slowly pull jaspersvts 2.93 car. i love my 2.76/4 port combo now but liked the straight 2.76 for what it did for a simple pulley swap and tune.

yes just try not to do any 4th gear WOT runs.

I've done quite afew 4th gear WOT runs with my 2.8" pulley.. hell I've done 20+ miles around 10 psi of boost in 6th gear before with the 2.8" pulley.. and no problems so far, with almost 75K miles on the car

2.76 that way you can slap a 4lb lower on later and have a beast combo. My car when i had just a 2.76 would SLOWLY pull jaspersvts 2.93 car. i love my 2.76/4 port combo now but liked the straight 2.76 for what it did for a simple pulley swap and tune.

2.76 end thread...

 

[SLEEPERSTATUS]

Pully combo in thread

 

[Presteige]

I had the 2.93 with the 6lb lower and LOVED the combo.... made over 500rwhp on a ported steig 3

 

[Zeekmann]

getting the 2.8 put on this week, will post my numbers. My tuner said it was the best upper setup so I went with what he recommended

 

[vladSVT]

So when does exactly the MAF pegs? around 500rwhp? Because I am at 503rwhp 485tq and my dyno sheet shows perfect A/F ratio, and car runs good.

2.76 FTW!!! I got a 2.76 with steg stage 4, Kb bap, and other bolt ons sitting slightly above 500rwhp right now, thinking about adding a 4lb lower hopefully make around 530/515 or so... But ill need 60lb injectors and a MAF for sure

But in all I love my 2.76 billetflow, no belt slip, super sleeper (I still have the stock pulley guard on) :fm: haha people ask me what it has done to it? I say nothing besides an intake :rolling:

 

[mikeshimek]

i went with a 2.76 and made 422 and 444 on a mustang dyno. pretty sweet setup, but my boost falls off about 4500rpm.

 

[KINGCOBRA86]

i have a 2.93 upper only with cai and cat back and put down 445hp 450tq, i might do a 4lb lower, but after reading this... i might put a 2.76??? idk any more lol

 

[JustaGT]

2.93 with a lower or a 2.76 upper only

 

[KJ04SVT]

I run a 2.76 upper with stock lower pulley, got 467 RWHP 468 RWTQ pushes about 14.5 lbs of boost.
