Thread: 3.5-2.9 drop...OMFG!!!!

you need more injectors, you shouldnt be retarding any timing. you want to have the timing as high as it can go befor it start to retard some for the knock your creating.

im kidding

A 2.9" on a GenV will require injectors, headers, intercooler and/or E85. No way around this, unless you want to run an unsafe set-up. Most will prefer a cam as well, to go with said mods.

Whatever seems to "work" for you though, works for me I guess.

So your running rich on stock injectors with a 2.9? You must have the polished rotors mod.

hell, if you were making that power with the 3.5, i'd have kept that. curious though, why everything else but no cam?

Or at least rockers

is a 3.2 feasable with headers genV fullsize ic and rockers?

i feel like that's right where you want to be

its feasible. i run a 3.3 with no ic and a 3.25 at the track. takes some work and some tuning and obviously all the right little things to make it work

I was under the impression that you'd need 40lb (or whatever) injectors to go 3.2 or lower on a GenV to get enough fuel in for all that extra air. But I guess keeping the timing low will let you run. Kinda silly, though, to make a $50 part the limit on your vehicle.

I was just amazed at how big of a change it was with the smaller pulley.

I know I missed this thread by a couple days, so I don't mean to back up on the time tables and then call BS but last time I checked a LQ4 was a V8 small block.... or did I miss a memo about something else. Is this the key to getting high end torque in a L67 with a Gen V? Seems extensive to me to only allow 250whp...

He's talking about an LQ4 MAF sensor...bruh.

It's just an external MAF sensor. That's it. You can use it on GenIII car's as well...I'm running a 85mm SLP screenless MAF. It does its yob.
