anyone know what turbo this is? its huge, 4inch inlet 3inch outlet

 

Big Diesel T4?

Here is what you do then...

www.forcedinductions.com give them a call

 

you need to measure the compressor wheel with a micrometer, the inducer and exducer. Thats a good way to find out exactly wtf it is

 

dont know if i am doing this right, but i took a dial calliper and measured the inducer and exducer of the compressor side. the inducer was 2.2inches(55mm) and the exducer was 3.2inches(81mm). They say the formula is inducer squared divided by exducer squared and then times by 100. So i took 55x55 = 3025
81x81 = 6561

3025/6561 =0.46 x 100 = 46

so does that mean its a 46 trim? that can't be. its way too big for that. maybe i am doing this wrong...

 

46 Trim T4 > 46 Trim T3

 

ya probably, but what does that mean for hp potential?

 

alot..lol what did you get it off of?
