Baby H1C
 

Out of all the threads I have read about the holset H1C's I havent heard of anyone using the smaller one.. Is there anyone using the 7 blade 44mm inducer one? It seems like it would be a fast spooler and just figured I would ask you guys to see if anyone had any experience with them.

no mine is the small 50mm inducer soon to be 60mm.

44mm isn't very big. It's still got a relatively large turbine wheel and large turbine housing too. It's going to spool much slower than another ~44mm turbo such as the 14b or even a 50 trim T3 (.48/.42) Why would you go with a gigantic turbine side for a mere 44mm is what I'm saying. The 14b or T3 will spool much faster and will be easier to run. They have a way better turbine vs compressor ratio (compressor is actually bigger than turbine as it should be on a gasoline application) and are a much better decision for a turbo in the 44mm range. Not to mention you can get either for ~$100. Or you could run a 60 trim T3 (aka Thunderbird turbo) that has a larger compressor than your Holset but still uses a way better sized 68 trim turbine wheel. Another option is a 16g that is closer to 47mm and retains the same TD05H turbine as a 14b, so will spool up great and get you to 300whp without much effort.

Thanks for the replies. I kind of figured that it was a lil unfavorable but just wanted someone to confirm it.
