LQ4 S480
Just bought my turbo today talk to the guys over at bullseye they are making me a race cover for the s480 turbo it will help it spool better its a monster turbo but will be good for both motors i'm doing. I'll post some pictures of the work as it goes on. Turbo will be in this week

i hate you!

You are going to be the slowest car on this site very soon it looks like!! lol |
I like the BW turbos. Their only down side is the size and weight.

Screw you Old Man Ron!!! We Are Heads Up Next Year IN THE HEAT!

hahaha ya its a really heavy turbo but good for about 1300 hp it might be a big laggy but thats ok its a huge ass turbo though.
|
couple stages of nitrous can get rid of any lag haha
|
Haha very true I. Want some lag if that Turbo was spooled at the line id shit my pants hahahaha
|
The lag won't be bad on that setup. The turbo isn't that big.
|
Its a 96mm its pretty big that's why I got the race cover but should be good for both set ups best part is it flows 120+!! And that's the number that matters most to you right? For tuning

Borg s480 specs.
* Currently the highest-flowing S400SX unit available, with maximum compressor flow over 120 lb/min. Will service1200+HP. * Wheel Dimensions: Compressor: 80.3 mm inducer, 115.8mm exducer, with exclusive Extended Tip Technology. Turbine: 95.5 inducer, 87.9mm exducer. Cast in Inconel 713 for high-temperature operation. * Housing A/R: Compressor .66, with 5.5" hose-type inlet, and 3.0" hose-type discharge. Turbine: 1.32, with 'divided' volute, featuring 'T6-style' turbine inlet flange(4.438"x2.75"), and quick-release v-band dischargeflange. |

* Wheel Dimensions: Compressor: 80.3 mm inducer Thats your measurement for adversized size. Thus the 80 part of s480 if it was a 96 it would read s496 The 120 lbs/m is definatly the number to worry about and yes that converts to supporting 1,200 hp at the crank :sFun_bananacolors: hope this helps |
the Huge turbo i have on my car is technically a 71mm and flows 81 lbs/m
which is roughly 800 hp at the crank in its sweet spot of the compressor map, that doesn't mean it wont support 900, it just means ill start pushing it past its efficiency at 800 crank. So at 15% drivetrain loss if you can put down 900 at the tires then your turbo will be happy because your making about 1,135 at the crank and that's being conservative, anything below that and your turbo will be basically too big . and i don't mean inducer wise on the compressor, i mean trim, and a/r wise on the compressor housing. |
Its funny because thats what i said to the guy that i bought it from at New Era i said this is a 80mm turbo and he said well theres a few different ways you could describe it but technically this is a 96mm and i was a little confused so this actually isnt a "big turbo" at all should be good for the build Either way just like you said 120 is the number to be thinking about. And its not rude i'm just learning about the turbo build i appreciate any help thats what these forums are for.
|
Awesome I was hoping you wouldn't take that the wrong way. But that Guy is wrong, only one way to look at it. Measure the inducer lol. But any way should be good but I think if I wereyou I'd consider getting a smaller turbine housing. There easily interchangeable. I'd try to get a. 96 a/r at least with a 6 speed. Especially with a t6 flange.
|
its kinda weird how alot of people talk about the compressor wheel inducer size, when the compressor exducer size is what really tells you how big the turbo is.

if you take two turbos and both have a 62mm inducer but one has an 76mm exducer and the other has an 82mm exducer, referring to them by the inducer size is irrelevant. to me its just not a good way to identify a turbo.
|
Ya i agree with that ...makes sense
|
There is a ton to turbo's. Far over my head. I just call Jose at Forced induction to place the orders and he nails what I'm looking for everytime.
I just know what combo's to build the motor's to help the turbo's spool and get the most efficiency out of them. |
That's who told me the s480 would be perfect for it. He wanted the s475 but then said might as well do it once and do it right so the s480 will be good ffor stock set up and even bbetter for a built motor.

Its just not a 96mm :) What the guy who sold it to you was trying to say , is equal to saying i have a 78mm throttle body with a 5 inch pipe and filter, so you could look at it as a 126 mm throttle body..........Fail. Don knows his shit, i know because i work for him :) If you Plan on eventually going auto then the divided 1.32 T/Housing will be fine, because once you spool it, then its stays spooled do to no loss of load from one gear to the next. But you'll see with a stick it will be no fun finally building boost in a gear only to have to shift to the next and having to start all over again building boost. Just to have to shift again , and again. lol |

exactly thats why i was switching to an auto in the first place so i dont deal with that haha. or get no lift shift like my buddies 9 second talon its a blast to drive!!!!!!!!! just keep it to the floor from the launch on nothing like it |
yah doug!!!
|
Yea doug I just added q Borg Warner S475
T-6* / 1.32 AR exhaust housing 96mm Turbine*Wheel 5" inlet compressor cover 5" outlet exhaust housing 75mm Cast Compressor Wheel Ngk afx 60 # Morton's and a bigger 255 walbro What a difference |
you guys should look into the new billet compressor wheels that have been coming out

i think billet wheels have alot of benefits.

that looks like a SHIT LOAD more work then it would have been threw the top. LS's come out pretty easy threw the top. just pull the intake and rad/ac condenser. nice work none the less out the bottom with no lift!
|
You would be shocked man it was very easy to come out the bottom plus i have a new k member to use. 6 bolts and it comes out of the bottom.....6 bolts, strut mounts, obviously all the wires. Id say a total of 6 hours and it was out. Those hours included removing the torque arm, trans crossmember.
|
ive done it plenty with a lift out the bottom on the lt's. the ls out the top. either way same shit the job gets done! haha
|
hell yea man thats how i dropped my lt out it was fairly simple took me 9.5 hours ,though my pass long tube header was real tight and stuck what a pita it was !!! yes since ive added the changes the car runs way faster and pulls way harder also added a huge front mount and solid one piece piping > do get some lag as to the garrett t-60 spooled fast and had no lag kind of liked the t-60 for my setup better but wont no till the spring when i can really test it . Might throw it back on to see the difference now that i have plenty of fuel. Doug cant wait to see ur car this year when u think ull be done ? do u need a hand also?
|
I gotta go for a rip in yours. I'm glad your happy with the set up!!!! You should run e85? I bought 120lb injectors and just gotta figure out my fuel set up...Tripple 255's i think.......I'll let you know if i need a hand. But anyone is more than welcome to come hang out theres always beers at the garage haha. I want it done by april. Its just the transmission thats slowing me down not cheap....rear is basically set motor is just waiting for my new control arms to go with the tubular K member then my buddy is doing the cage with the piping. He bought a bender and we are doing a 4-5" downpipe out either the front bumper or right behind the fender. :)
|
Rookies.. 8 hr's I can do a full motor swap.. LOL
The top is quicker but out the bottom isn't bad. |
Quote:
haha im not up to 8 hours yet but this is def my frist one. I'm sure you could do these swaps with your eyes closed by now..... :) |
Damn slowhawk 8 hours for a whole swap your crazy lol!! doug yea man when ever u wanna ride rip down 57, i gotta get the damn car registered again should of never took it off the road so much for snow this year!!! Doug are you building just for strip or street , i hope street to !! and im down for some beers!!!
