My bastardized V3 Ti took a dump on the Dyno and I’m purchasing a new head unit real soon. Back and forth between a Ti and JT (a hair smaller than a YSi)
My goals are 650 to wheels with as much torque I can get. E85, id1000s, and plenty of fuel pump, stock heads.
i have been seeing people break that 600 mark on Ti’s all the time now. Even some 700 on pump.
Main question, is it better to spin a Ti at its peak than to not use a YSi to its full power? Best slip isn’t an issue, I’m likely moving to a full cog setup. Currently on a ATI with a 2.87 with 32/30.
I just dont don’t want to regret not going bigger, but I’m not gonna wanna make more than 650/600 anyways. A wastegate setup could be an option too.... YSI and bleed off extra boost.
Am i have issues with a RFL getting rid of enough bypass?
They don’t really, which is why mine was referred to as bastardized. But the Paxton 1500sl would be an equivalent to a v3 ti. The thing is the v2>v3 bearings.
just did the math, I spun the v3, rated for 52k, at 68k with my new ATI pulley. I didn’t realize it was that bad.
Guess that will be why then lol
Better off with oem crank pulley.
I will be running my v3 around 60K which I think should work fine.
What's your pulley setup for you to be running that fast?

ATI 6.78, 2.87, 32/28, 7200rpm
It’s the same I used with OEM crank pulley and the V3 SCi with a shift point at 6900 and I had zero issues overspinning to whatever that was but I think that was only like 57k. I don’t remember.
It probably would have been ok if I installed the 928 bearing but I ran out of time and paid the price.
Im gonna be running this same thing to start with on the V7 which should be no problem as long as it’s not too much boost. It’s got a slower step up ratio that will put me right at 67k @7200 rpm not accounting for any slip.

How big of a Vortech should I go.
