In the first dyno flog of the newest design Billet 80mm compressor wheel from Forced Inductions for the S400 turbo, a 249 rear wheel horsepower gain was realized in comparative testing against the cast 80mm wheel.

Cast wheel made 1040 with the gate pinned shut making 23-24 psi. Billet wheel made 1289/1107 @ 29 psi with the gate pinned shut.

Both turbos had the 96/1.32 hotside. A 1.58 housing will be tested shortly.

Been trying for an hour to get photobucket to work and cant... i have pics of the turbo to post if i could get some help.

 

More details on thet engine please. Those are some awesome numbers.
Turn that down to 20 psi and you'd have one hell of a car/truck that has a bigger bullet to load into the chamber if need be!

 

That is big power out of that unit. I wondered what a billet wheel would do in an S400!

Here are pics of the wheels and of the actual turbo!

 

Email sent... Thanks man.

 

After seeing that pic, I'm even more impressed, THAT is a beautiful wheel.

 

I need details on the engine.....I am running an S480 on a 6.0....But haven't dynoed yet.

 

Video too if you have one.....

 

yes engine specs please, I was looking to get that turbo well actually 1.10 92mm.

 

Awesome gain on the Billet wheel. Think i'll swap my cast s480 just because of this. Obv not a stock motor running 29psi

 

Anyone making a billet 75mm for the 400?

 

^^^^this here, i have a brand new s475 from FI and i am wanting the new billet wheel for it...

 

Awesome numbers

 

the s480 cast, was this done with the race cover or standard cover?

 

Unit was done with modded race cover.

 

We make the 75mm billet now also in the new staggered hub design as well and also staggered hub with 11 blade ETR too,..

 

Prices? Shelved item?

 

what would be a better bang for the buck, s475 upgraded to cast 80mm, machine cover, balance, or s475 upgraded to billet 75? (s475 is 1.32ar 96mm t6)

 

For you? Probably a 75 billet. Keep the wheel weight down and you ARE maxxing that turbo out, lol. Another 150+ BHP sure would make a difference in your car without being detrimental to spool.

 

Very nice, thanks for sharing

If you do that new housing and post results i will give you a handy

 

Very interesting. I have been looking for a wheel upgrade on my S480. Is there any way to get a 23-24 psi comparison with the new wheel?
