Planning my build for the near future. I realized I don't have room for the DP a big single would require so I'm looking at twin BW's. I can either do a forged 347 or 370 and want to know what set of BW's would work best for my goal of 900-1000 WHP. Car is primarily being built for the track, but want it to spool quick on the street as well. I figured the 370 with the S366's would be the best option, but not sure if the 370 would be too much motor for them. Any help is appreciated. Details on the build:
TMS 347 or 370
Cam from Martin @ Tick
Decided Im keeping my old TFS 215's
LS1 intake
E85
Jake's Performance PG or TH400 (most likely 400)

Awesome, sounds like a stout combo to me and that's what I'm leaning toward as well. What made me wonder if the 370 was to big for those turbos, was seeing Silver_82 run mid 8's on a 5.3 with the same turbos.

Question for the general public, is there anything wrong with staying smaller cubes, (347 LS1) on a 76mm/91AR front mount car? I could punch my aluminum block out to 383 or so, but I feel that maybe for strength, leave it at forged 347? Goal is pretty high hp, street car.
Any feedback appreciated..

I've heard most reputable shops claim that the 370 is a great choice for a FI build because it uses the stock stroke (ideal for FI), shorter stroke than a 383. Plus, I can meet my goal with a 370, don't plan on going any bigger.
Thanks guys, would you say that the S366 would compliment the 370 perfectly, or is there a better set I could use by BW?
If you look at the sticky up top of fastest 1/4 mile times, one dude in top 10 runs a 347. Lots of power can be made with a 4.8/5.3 or 5.7

Although you can get FI or others to build you the 366's with a 68mm turbine as opposed to the 73mm anyway
Price is barely any different than the base 366 anyway. Or for a little extra, throw in a billet 66mm wheel

Smaller BW 6368 turbine wheel should make for much better spool over the 6673's. Although you can get FI or others to build you the 366's with a 68mm turbine as opposed to the 73mm anyway. Price is barely any different than the base 366 anyway. Or for a little extra, throw in a billet 66mm wheel

For 1000hp, the AGP turbo RS261 might be an option, physically smaller than the 300's and with better housing options. It's based on the S200 BW's
Or the BW 62mm FMW. Or cheaper version is I guess the S300 6368
