Im doing research on the future 12v build I have planned. Im really looking at Industrial Injection's Phat Shaft series turbos And was wondering if anybody has any complaints or bad experiences with them. Im mainly looking at the phatshaft 62 but cant decide to go with a 12cm or 14cm housing.

I know that Im going to have ddp 370s probably a 0 plate, 191s, HTT 3 piece manifold, and of course all the free pump mods and timing around 16* and Of course all the have to have like exhuast intake and guages.

Bump, Doesnt anybody have a phat shaft?

 

I dont have a Phat Shaft but they are supposed to be awesome. You cant really go wrong with Industrial Injection. Im not sure what the price difference is, but check out the Silver Bullet.

Have you looked at the HTT stuff yet?

 

Dunno why you'd want a 14..........stick with a 12. A 14 would just make it laggy.

I've never really heard anything bad about the Phat Shaft line, nor HTT or Super B really.

 

Will a 12cm flow enough for the fuel I want to move? I havent looked very deap into HTT yet.

 

I always figured the 14 would clean better and what not. I was thinking about a 14 not a phat shaft but a 14 on my truck.

 

How laggy are we talking with a 14? Im going to have a 5spd so I dont want to be throwing fuel around just to get some boost in town.

 

I have the HTT stainless in a "13" cm housing. There is a little bit of lag around town but not bad enough that I am dumping fuel for nothing. My understanding is that the SS version is not really a true 13 cm, so it may not be valid feedback. If you are building it as a project and looking to make some big power I think the 14 is probably the way to go.

 

But why the 14 over the 12?

 

Ive understood that a 14 will be cooler over a 12? does a aftermarket 12cm run cooler right out of the box then the stock 12cm? Im not going to huge HP number just around 400 youve seen my fuel mods above I just dont want to get hot when towing or hualing *** but I dont want to be a dog either.

 

It isn't worth the marginal EGT drop. I've never seen anyone get more than a 50-100* drop going to a 14 or 16 cm housing and afterwards they complain about the lag.

Go with the 12, you'll be fine.
