It's defiantly more then 25whp faster, just dropping the turbos on. Stuff like, breaking the nitto's lose at 50-60mph in 1:1 @ 1/2 -3/4 throttle is possible.
This thing runs so damn clean. There is no smoke on the throttle. There's still a little tiny puff to get going aggressively.
I did one full throttle pull in 4x4 rolling into 3rd about 35mph-I dunno. But I saw 70psi of boost, didn't notice boost or drive. Looking behind me, I couldn't see any smoke. The single would be a smoking like crazy, struggling to make 50psi on the same run, and I've done this same run several times. The butt dyno suggests faster.
So, once I figure out where that primary is at boost wise I'll start tossing darts higher on the SSR. I could hear a decent turbo whistle on that 70psi run. I just hope I'm not over driving that little guy.
70psi in 3rd on the same tune that could almost make 58 in OD.... LOL that's bad ass.
