i learned how to read a compressor map from corky bells "maxium boost" and some of the formulas

 

thank you and you're welcome. what do you mean about the forumlas thing.....

the basic forumlas are listed above to find out an engines airflow at a certain rpm. where the really experience comes in is choosing the variable (VE) . there are alot of variables in turbo math, but i'm nailing each one down year after year. VE is my current demon.

 

Yeah, that sounds right. The 50 trim compressor is great, but just wont flow what some of the larger TO4E's will. I wish I had a compresser map for the GT3037, but from what I hear it is an awesome turbo. Im trying to figure out which ball bearing turbo to go with on my sr20. The GT3037 is a little bit overkill for my power needs.

 

GT2835 will work wonders then. I have a map on the 3037 and it is like a 50 trim and a T58 combined. But i cant get that 52 trim compressor on a big enough turbine. Did you know i had a Gt2510 on my SR20? at 12psi i made 267rwhp on a stock motor. at 15psi my S14 ran a 12.46@109. it was a great little turbo.

Any of the GT series turbos will work great Gt2530, GT2510, GT2835, GT2835R

the 50 trim loves life at 10-22psi. i've seen people choke the turbo above that boost level cuz the motor flowed too much air at that boost level. The higher trims of T04e's are made for higher boost levels. each compressor has its own characteristics.

 

wow......all the math involved here...


i simplified it all in my case and went with the best deal i could find, $2700 on a stage II revhard kit.......im only running 7psi on an ls engine, but its fun so far.

 

no i meant brain sorry yeah there compressors you know what i meant when i said that by the way you sound reall smart on the internet

 

yeah pure giberish when i speak in person.
