BOOST info thread for turbos and blowers

DEMON44 said:
That all true.....but you do not have to add fuel if you don't want to....... Unlike a boosted gas engine. You see what I'm getting at.

I can still get 20MPG out of my 500 horse diesel it just depends on how I choose to drive it.

If you don't add fuel you WILL NOT add HP.
 
of course thats a given. I was refering to what he said about leaning out the engine with more air........you can put all the air you possibly can in because the engine doen't meter air. your right foot meters fuel added, and obviously hp produced.

Unless you already have more fuel than air...

How many guys crank up the fuel when they install a Turbo on a 6.2L? Do they gain power?


Talking about that low level of boost pressure, I wouldn't be amazed to have the Vortec system keep up. I mean there are multiple supercharger applications for those trucks running the stock fuel system and having it keep up. Just a matter of a PCM retune in those cases. However, guys making real power with blowers are the ones I see changing fuel systems(Marine intakes being the hot ticket, though $$.

I just don't know enough about turbos to help beyond this advice. Sorry. At that low of a boost level, I wouldn't be concerned about building a bulletproof bottom end. Reliable? I'd look at reducing compression. Vortecs are in the upper 9:1 range if I remember right. Something more like 9:1 would be a little insurance.

You guys do realize that there are tons of people with blowers pushing 8psi all day long on Vortec trucks right? Not to say some don't go boom, just not really THAT much boost.
 
thanx sled dog that my whole point, I know wipple makes a bolt on kit that you just bolt it on plug in a chip of sorts and go. I belive they make 8 lbs or 12 lbs depending on what pully you put on the blower drive. Why not just go that route? well one its spendy, and 2 blowers arnt free power like a turbo is they reqire power to make power. And 3 it still dont sound as cool as saying i have a twin turbo 350 lol.

As an update, I have a friend that claims he can get me diesel turbos At cost. But he has to look to see if he can get gas trubos at cost and get back to me. I dont know what the differnce is but he said hes sure they are differnt.
Not taking in to account the cam, I can rebuild the engine with 8.75:1 blower /turbo pistons for about $640 IF I dont have to have much machine work done. Id like to stay stock bore and just have the head surfaces cleaned up. I am going to use an 010 4 bolt main block, with stock vortec heads.

Some new figures with lots of extras and still under $6000
pistons turbo/blower 8.5:1 $504
cam shaft turbo $150
gaskets $45
bearings cam clevite 77 $20
bearings main/rod $60
balancer scat powerforce $52
edelbrock E-tec 200 heads $1100
edelbrock gear timing $160
head stud kit $160
main bolt kit $68
long block total $2319
TURBOS t3/t4e-50 X2 $1489
ram jet intake ecm harness $2100
total $5908

I realize this still leaves plumbing and other stuff but it DOES include ALOT of un-nessisary goodies. should be around 600hp still and reasonable for the power/price

I'd say do it. Theres nothing like the uber cool factor. and for 6k thats a reasonable performance build budget.
