New BW EFR Turbo Thread

Normally, a larger turbo with the same restrictions are much laggier then the smaller turbo. I've tuned turbos where an inlet change would pick up 40+whp and 400rpms in spool. Anyhow, the TS 7163 spools very well.

I know this probably won't apply to any of you but i'm after a bit of advice. I originally wanted to use an efr 6758 t25 as my power goal isn't any higher as 450, however i can now get a 7163 alu cored ts turbo for only €150 more.
Btw, a 6758 ts is an option too at only €80 more than the ss 6758
It's for a fwd car so torque would be limitted anyway, also i'd have to fab a mani for both so no problem in that regard...
How do ts cars sound compared to ss? Because of the restrictive nature of the original ts turbo it sounds like a coffee machine, wonder how that works out with the BW's.
Your views are highly appreciated!

If i stay in Nasa TT3, i honestly considered a twin scroll 6758. It would allow me to stick to 93 and stay at my power levels which over around 340-350 wheel. I have a feeling it'll also be lighter than the stock turbo.

i'm running stock turbo on stock long block and e85 and i have trouble keeping the HP down this year, i'll actually have to add 200 lbs of ballast for next year.

don't forget the rule change for TT3 next year. 10:1 weight/power ratio and new calculation for average HP, not peak HP anymore.

I was previously tuned to 311 Max, and running the calcs it seems my average is 300-303, depending on how you interpret the graph. I'll need to get tuned to a 335-340 hp average to hit 9.6 on the current calculator, which should be a 10.0 on the new calculator if estimates are correct.
Honestly, e85 is great, but with e85 comes a much greater uncertainty in your final weights due to the volume you'll use in a session. From a rules compliance standpoint, 93 is a much better choice of fuel. Your weights will also be more consistent throughout a run, though i doubt most people could feel the difference.
Oh and one more thing. Fuel makes a great ballast
