F1X will be in the car by mid may and hopefully we can make all the power without any belt slip, need to figure out what pulley combo to make 20psi on a stock cubic lt1, and what belt to run

The D1sc will usually max out around 800-850 rwhp in a stick car... I have seen some claim to make more but...That's the norm.
YSI on the other hand is usually good for 1000-1100 rwhp on a good combo.
I would have sent the YSI in to Vortech for an inspection....
D1SC is a damn good blower but, you ain't gonna make YSI power with one. Hell I had an F1R and couldn't make YSI power.
F1A-94 is the way to go for 1k rwhp.

Its was either a belt slip or belt stretch, all people I know who ran the same kit i had ran the same problem where they always had belt slip, nobody made the power the ysi should put to the wheels when running the ysi on that kit

Finally finished the car with the f1x and belt slip problem that i h had before with the ysi is solved,
I really like that now it doesnt have any belt slip and can feel the power progressively, but didnt like that it doesn’t have the torque or the pull that the ysi had, it made 803 on 13 psi pump gas, that was on a 4.75 pulley at 7000 rpm, impeller speed is at 66500 rpm,
With the ysi get broken it made 865 with 21 psi with alot of belt slip
F1x made 803 on 13 psi
Both on pump gas

My belt is slipping now too over 6,000rpm. I have a 10 rib, 8.3 lower, 2.75 A&A grip upper. I'll ask Josh/Andy, but the correct way is to lock out spring loaded, pry over manual tensioner, tighten, then unlock spring loaded? Red is RPM, Yellow is Map which should continue up with RPM but is sloping back down. Don't know why the pic wont go right side up.

Dave DONT DO THAT, it will put a ton of load on your head unit bearings and will break your ysi, mine broke because of that and it had lower than 2500miles on the unit (everything was broke), try to send your idler to andy and let him set up ththe spring tensioner on the soft spring setting, what you are have is belt stretch at first them you are having belt slip, try the grip tech pulley I think that will work better than putting a pry bar and applying a ton of load on the head unit
