For those that have gone turbo.....
« Reply #15 on: February 09, 2007, 02:41:32 AM »
it is all about mathematics people...
i know a few things about engines , but all the work is done by my friend ( chriss that is a mechanik )...
it is easy to calculate.. the 318is engine is 140 hp in atmosphere pressure , so if i put 1 bar extra pressure , theoreticly will go 140 + 140 = 280 , because it is 1 bar from the atmosphere and 1 bar from my buddy garrett... so if you play with the head , exhaust and pistons , rings , crank , ignition and other goodies in the engine , will go to 300+ , and then you can hunt down E36 M3 for fun...

i am going to this setup... ( we - me and my friend ) are going to start working the car with 0,5 bar , because the car has 170.000 km , to see how it goes with , and then , if everything ok , will go for 1 bar or 1,2 bar of pressure...
the setup is taking a long time , because we are fabricating all things by ourselfs , that is we are making all thing hapend without paying anybody to do it... my friend is working now for a month in the exhaust manifold ( it is taking time because he is calculating the angles and everything to have 100% efficiency ) , and i have just connected the smt7 , and waiting for him to finish the manifold to go on..( i need to know where exactly the turbo is going to be to fabricate the intercooler arms and the hood ) i have all parts needed , that is 440cc injectors to replace the stock , intecooler ( the setup will be v-mount , with a slight change in the hood ) , top mount garrett 28/60 turbo with internal wastegate , oil cooler , smt7 - boost controler ,gm map sensor 3 bar , smt7 ignition controler , smt7 injection controler , smt7 shift light ,generaly all the goodies that smt7 has. im i fogeting something ?

The car is going to be altered externaly to go along with the turbo setup , i have just finished the rear diffuser , i have done the front , and as i said i am waiting to get the hood done.
i am taking pictures as we go along , and will be posted when finished ...
steer with the rear !!!

assuming ambient temps and charge temps are the same twice as much air should give twice as much power,
I have seen that number go both ways, getting more then twice the stock at 1bar and getting less twice then stock at 1bar,
reason is mainly turbo and intercooler setup,
