2.93 vs. 2.76

[uwood]

2.93 4lb lower sweet combo

Quoted for truth.


I love my combo. I just need a retune. Original is extra safe.:bash:

Whats a good place 2 buy a 4 pound lower and i have a 2.93 i want to swap 2a 2.76 for the drag strip i have a basic preditor 91octane pulley tune do i need some other tune or will it work

Guys, I am getting a 2.93 and 4# lower with the tensioner notched and 3 100mm and 1 90 mm idlers. I am getting many conflicting belt numbers for this and where is your lower idler at: upper or lower?

2.93 upper w/ 4lb lower if i got pulleys.

This might scare you into not wanting to run an aftermarket lower.

Lower ilder in the upper position for a 4 lb pulley.

Lower ilder in the upper position for a 4 lb pulley.

Great and are you running the K080810 belt? Thanks BTW! :rockon:

I have seen people not max out their MAF on a 2.76 in warm weather , then drive it in the winter and max it out.

Exactly, so this is why I always say go with a 2.93. Not worth the possibility of running out of MAF and running lean. If you're already prepared to deal with this issue then go for the 2.76 but honestly I don't see the point for 5-10hp.

would a 2.76 and a mafia reduce the maf pegging? i have an xcal3 tuner, are the two products compatible?

Yes the MAFia would keep the MAF from pegging. They are referrring the stock MAF which can only go so far to provide enough fuel, the MAFia extends those limits.

I'd pick both, run the 2.76 without a lower and 2.93 with a 4lb. That's what I'm planning on doing.

 

[cobra04972tx1]

what combo can you run with a 6lb lower, 3.1?

Whatever combo you want to run, there is no set pulley combination set in stone. Just what people tend to lean towards based of what others have done. Some choose to go with a 3.1 upper, others a 2.90, and some even a 2.80 with the 6lb lower. It's whatever you think would work best and what you're car has the fuel to support.

Well a friend of mine just called, and he is getting rid of his 6lb lower and wants to give it to me, so I was wondering if it would still work with my plans of having the 2.76 and 2.93, and changing when I put on a lower. What fuel upgrades would be needed with a 2.90/6lb?

If you're ported you will most likely need a MAFia and BAP. Your injectors will probably be fine.

 

[cobra04972tx1]

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

2.76 and a 4lb lower wont work?? Jw why everyone says to run the 2.93 with the 4lb lower?

It will work, just more chance of belt slippage and overspins the blower a bit more. It's still a proven perfomer from what I understand.

 

[strokedfox347]

Fair enough makes sense
