So who is gonna be the first rb to try one of these out? I was hoping someone was going to come up with a compromise between the 60-62mm & 67mm ranges. The 4088r (63.5mm) and BW 8875 (63mm) just seem too laggy from what I've seen. The dyno's from SP seem most promising (except the bb only price of $1750).

This is testing done from Sound Performance on Supra motors. Below is from what he posted.

"This was on a 3.4L 10-1 CR 2JZ with cams and all the turbos were all in!"

"Now look at this next dyno on Reid's car, (This is a 100,000 mile completely stock never opened supra motor) the 64 out spooled the 67 and made more HP showing that when inits efficiency range it outperforms the 6766, not until we went all in like on the 3.4 motor did the 67 make more HP"

How much do you want to sell it for?

Honestly the 6466 is very impressive, I was following the SP threads like an obsessed stalker for a few days until they posted all the results.. Being DBB its a little pricey.. and I with my past experienced with a DBB and their rebuild costs I wont buy another..
