SmoknR6 Posted May 6, 2005 Share Posted May 6, 2005 i know this is a stupid question, but i am new to the world of forced induction. I was just wondering what kind of turbo i need for a v8. its just a single turbo set up and im not planning on running huge amounts of pressure. i just needed some help picking the turbo. oh and its a blow through set up to. thanks Quote Link to comment Share on other sites More sharing options...

How many ci is your engine, what do your heads flow, and what cam are you planning on using, and we can start to figure out a turbo for you. For example, I have AFR 220s, with a custom grind turbo cam from cammotion, Im using a GT4276 and at 16-18 lbs Im hoping to make 1000 hp at the flywheel...

SmoknR6 Posted May 6, 2005 Author Share Posted May 6, 2005 Im just looking for roughly 400hp. I havent flowed my heads but they are stock vortecs. My cam has 114 degree lobe seperation, and has 440" lift. I dont know the duration, I couldnt find out from the guy i got it from cause he didnt know. I have a lot of compression so was thinking of keeping it under 10 lbs. Im also at 4400 ft above sea level. Quote Link to comment Share on other sites More sharing options...
boodlefoof Posted May 9, 2005 Share Posted May 9, 2005 if your goal is around 400 horsepower, you don't need forced induction to get you there. But, for some info on turbos... check out this link... http://www.turbofast.com.au/javacalc.html Quote Link to comment Share on other sites More sharing options...
SmoknR6 Posted May 9, 2005 Author Share Posted May 9, 2005 yeah i actually had a powershot kit from an old project i was going to use, but i thought it would be kinda fun to build a turbo system. i have never done it before and figured tryin it would be the best way to learn. i decided to go with twin T3 45 trims. Im going to start building the log headers this week. Because of my compression i am only going to run around 8 psi. The only thing i am not looking forward to is tuning the carb, but over all i think it will be fun. Quote Link to comment Share on other sites More sharing options...
Guest shawn Posted May 9, 2005 Share Posted May 9, 2005 what size v8?i have a 383,with 9.0 compresion,and i have a dual ball bearing t88..but if you have a smaller motor,you could get away with like a t66.. Quote Link to comment Share on other sites More sharing options...
SmoknR6 Posted May 9, 2005 Author Share Posted May 9, 2005 i have a 355. pretty mild actually and 10.5:1. so i will use the boost conservatively. Quote Link to comment Share on other sites More sharing options...
