Not quite... Only pulls to 7,400, then it falls off about 10%.

Redline is 7,750

Stock is where it's at.

If I were building a car for road racing a Mopar Stage 3 or upgraded Stage 3 would be my likely choice although the new Borg-Warner EFR are mighty tempting for the power and spool characteristics. Lots of great turbos on the market today that weren't available just a few years back.

Eric H. - '04 Neon SRT-4 (eBlue/S2) - '04 SRT-4 (blk/stock)
'92 Dodge Daytona IROC R/T --- -- '91 Dodge Spirit R/T
plus a couple other turbo Dodges, a Cobalt, a couple Focus, a V-wagon, and some other stuff...

By design most log manifolds are going to fall into the crappy category... The work, but not nearly as well as a well built tubular...

I run a vband .63 TiAL housing. The vband also helps smooth the air flow to the turbo and improves the spool.
