Default New turbonetics billet 7575...

Should be buttoning up my On3 A/C Turbo build today with one. Did take it for a quick spin around the block when it was all said and done and seemed to build boost right around 2500 - 2800 at wot. This is with 317 heads and Tick Turbo cam 2 on a normal ls1 bottom end. Pending I have no cooling issues, should have dyno numbers next week.

Yes BB. I don't believe it comes in JB but not sure.

Made 1000w on 17lbs as twins on a 427. Spools awesome. Very happy with it so far.

These are only offered in Ball Bearing. We have MANY customers running these now and quite a few over 800 rwhp already as well. Proving to be very potent turbos!

We keep them in stock as well so you don't have any wait/build times along with the very best pricing

Everybody takes the 78 cast over the 75 billet, but Reggie at Turbonetics even said the billet flows more. Jon, do you have flow numbers on all the different sizes?

Yes he is absolutely correct! The Billet 75 will outflow the cast 78, and as a combo it will also spool quicker as well!

I will see if I can get some flow numbers for you guys as well

Hey bud, granted that's a little bigger than my 403... where are these things coming to life and where are they in full spool on the 427? may be a stupid question, but how do they sound? What do you think they'd see on 25-30psi? Thanks in advance.

I did a billet 7575 on a friends 03 Cobra that we got from Huron Speed. On the 4.6 it lights off fast and feels good on 10lbs but the car keeps eating fuel pumps so no numbers or big boost. One thing I noticed is that the 7575 is much quieter then the 7875 I had on my Camaro.

Should have consulted your fellow LS1tech sponsor Huron Speed

We always have the very best pricing, if not we will match/beat if you find it cheaper elsewhere!
