Bullseye S480
 

Got my new turbo in yesturday and this thing is huge 80mm cold side and 1.32 hot with 96mm trim . Here are a few pics. Enjoy ! The turbo next to it is a PeakBoost A/R70 with a 1.00 hot side

Hi,
I have one myself.
I think they are a great turbo
They will outflow any equivalent sized turbo on the market
They (S480) has 8 compressor blades as opposed to the Garrett 80mm comp wheel which has only 6 blades, that's ~25% more airflow!!
They have extended tips so they hold more air flow and boost pressure
You definately made a good choice there

That's one big boy you got there! Did it get dropped on the turbine housing?

bad ass turbo.

Hello pmr , from what I hear of everyone I talk to that are running this the tell me nothing but good thing about them . You have yours up and running yet ? How it spools and poweband thru the rpm's ? This is strickly for drag racing can wait till all together up and running .

Hi mono4 , yes it is . That glue from ducktape that was on it .

Hey Thanks TT get ready 4 whats coming .

Seems like everyone is going with this turbo nowadays... I can't wait to see what it can do. Not sure about the 2 extra blades giving 25% more airflow though... doesn't make sense to me.

did you go with the standard or race comp cover? i got a 475 with race cover. i cant wait to see this thing in action.

It doesn't work that way my friend.... Though it IS a better design :icon_tup:

That is a standard cover. Should have been around 800 bucks. You can get the BW480 with the race cover direct from BW (177287). They are only around 1000 or less from a diesel shop....

i paid well under that. lol

Cool deal...yeah. A diesel shop in FL had them for 699 new shipped to the door. My buddy picked one up 2 months ago. Working great....just a touch laggy though. But hey.....spray it!!!

I went with the standard cover since you dont gain that mutch with the race cover , here is the link to bullseye check out where it talks about the new race cover http://www.bullseyepower.com/news.asp?id=49 .

LOL , call bullseye and try buying one for that ! like you said for diesel are 1000 or less for a car it would trim , exhaust housing ahd manny other things to your specs and needs and these such things cost more . here is the bullseye catalog with different size turbos and prices http://www.bullseyepower.com/catalog.asp .

i am really thinking of going with this turbo myself, but i am wondering if i really need the s480, as apposed to the s475. If anybody is familiar with both of these, is there any noticable increase in spool time between the two?

What are you going to use for the street racing or drag racing only ? what makes your spool up laggier or quicker is your exhaust side thats what you need to consider for the quick spooling the cold side is the amount of air you want it produce.

Correction: A properly sized "exhaust side" can and will help with the "spool up". But it has more to do with the balance between the wheels.

well, a peripheral port s475 or s480 with a 1.32 turbine housing. i would be getting the new stlye race housing. the engine is already starting its build, but i have time to think about what turbo i am using.

Hi,
I just finished my studies for the year, therefore have been busy with that and have done very little on engine
I have bought some parts and planning to buy some more in the coming months
My engine will be ready to start probably in a year or two
It's hard for me to save up money as I work part time and have no time to work any extra hours because of my studying commitments
Things are looking up though, I have 3.5 months free now, to work and make money, so I like to save up the money needed, to hopefully complete a large portion of what else is required on the engine

The exhaust wheel and housing is quite large on the S480, therefore I'd probably go with a smaller diameter manifold piping if you're worried about spool

More blades do infact increase airflow
8 vs 6 blades, 2 blades difference = 25%

Yeah it does...

Oh Awsome..... Im having the CNC machine cut me a compressor wheel with 657 blades on it so I can make 38,964hp!!! Thank you for your help bud :icon_tup:

Lol ok, without the airflow data (I can't find any S480 data) it would be hard to figure out the exact difference
~25% is pretty high but can we agree that the increase airflow will be quite signifiicant?

dude can i get one!?!?!? lol

I can't tell you the exact % of increase, but I will say that I'm sure I know why BW did it and IN THIS CASE it probably is more efficiant. But, just because a compressor has more blades doesn't make it better. In a lot of cases it makes it worse. It has to do more with the shape, pitch and angle of the blades and how they work together not only with one another but also with the housing/inlet.

There is no way in hell just adding additional compressor blades is going to linearly increase airflow like that.
