i mean like

-Wheel- ? Trim - ?Inducer / ?Major
-Housing- ? Inlet / ? Outlet - ? A/R
TURBINE:
-Wheel- ? Trim - ?Major / ? Exducer
-Housing- T04 inlet / Insert type outlet - ? A/R

can some one fill in the question marks and or explain what the trim\inducer inlet outlet, wheel trim housing should be??

for example the specs for the HKS T04E

COMPRESSOR:
-Wheel- 57 Trim - 56.3 Inducer / 75.0 Major
-Housing- 100 Inlet / 60 Outlet - 0.60 A/R
TURBINE:
-Wheel- 62 Trim - 74.1 Major / 58.1 Exducer
-Housing- T04 inlet / Insert type outlet - 0.70 A/R

How much horsepower are you looking to flow?

20G, the only spec you need. Diameters don't really effect flow as much as you would think, blade layout does.

[Talon007]

You definetly dont need a 20G for that HP, a Big 16G will be enough, for your requirements

[kjewer1]

A 16g would do it but not by someone asking the above questions The average guy is better of doing a 20g or a 50 trim, since with average tuning those number are possible. Then with more knowledge and expereince he'll be able to do that at the wheels On the 20g I trapped 119 mph, which is about 430 HP for cars that weigh what mine does. 50 trim can do that on pump with good tuning. Thats just my opinion though. 16g is a decent turbo, but 95% of poeple who upgrade to it dont keep it for a year before they want more. I borrowed one for 2 weeks, ran 12.0 at 114 on heavy 2g and gave it back Spools real fast though...

a 16G will never make 450 hp, ever ever.

[turbo2nr]

so 20g it is..

thanks again..

A 20G will make 400 no problem. A Big 16G will, you might have to actually spend some time tuning the car

[turbo2nr]

tunning the car isnt a problem.. i plan to tune it anyway.. thats the only wat to bring out the full pontental of the car..

I never said it will do 450, but 400-450. But lets look at this. If the general rule of thumb, which has been around since we were all in diapers, is 10 hp per pound per minute of airflow, why is so hard to believe that a 16g will do 450 crank HP? I find the 10 horse per pound/min relates to whp more than crak hp, and I got my 16g up to 40 lbs min. Even at only 15% loss, 400 whp is still 470 crank. I got 47-48 pounds/minute of my 20g, and traps at 119 at only 45 lbs suggesting 440 wheel hp based on the calcs and on other poeples traps vs dyno pulls, like Dre. I dynoed 380 WHP a while back with 38 pounds per minute flow. So I stand by my last post. I'll be dynoing again with the new turbo at 55 pounds per minute, so well see how it relates then. Sorry if this post is an incoherent ramble...

[turbo2nr]

no if i am correct the 16g will spool faster then the 20g right?

if it does does a 20g take a wile to spool? i heard that it start around 2500-3000rmpz..

thnaks

I have found the 14b spools at 3k rpm, the 16g around 3200, and the 20g around 3500. I used a TDO6H 20g and even that spooled by 3700. A TDO6H 50 trim I ran last year spooled by 3700 as well. Now my TDO6H with GT30/40 hybrid compressor wheel spools by 5k in second and 4500 in 3rd/4th. Anything up to a 20g isnt even worth calling lag. When you shift boost comes right back. And if you floor it and dont get boost, you're a fool for flooring it before 4k rpm anyway, downshift already... My current turbo though will require no lift shifting to ET well. Seems that after the 20g is the jump off. Everything up that point IMO spools plenty fast. In fact, I now believe the 20g is the ultimate street/strip turbo. Big enough to make great power, but spools fast enough for fun on the street. Just my observations though.
