Depends on how much power you want...1000cc is probably OK for 91 (maybe w/ meth to be safe) for over +550whp, but not for e85...I needed a twin pump and I had to upgrade from my ID1000cc for my e85 setup (I currently have 2150cc, but I don't think I needed all of it...)

Well don't have great news but have good news the ti blower made 604/445 with an extremely slipping belt at 17psi and every pull after that was less n less psi with more n more slip. This 79.5 belt w the 3.12 pulley was maxed out on the tensioner and still loose and slipping, so we swapped to a brand new 79.5 belt w the 3.12 still and the brand new belt just would not hold on with the new belt it did not see above 16psi so we decided to give it a rest. Unsure if the belt needs to be broken in more but I saw consecutive 20psi pulls a few days ago so I'm confident this blower with the 3.12 pulley can deff see 620-640 whp and I cannot imagine w the 2.87.. 👍👍

Sorry to hear that!
That's why I asked you if you had plenty of adjustment left.
If you can bottom out the adjuster, then You need a shorter belt, 79" is the next size down.
What belt were you using with the 2.87?
Belt dose not need break-in. But after first install of a new belt it may stretch a little and need to be readjusted after 100 miles or so.

I predict with the 2.87 you'll be in the 23-24psi range and 650-675.
When you think you have the Belt pretty fight, take it up a 1/2 turn.
Do a Dyno Run. If you see any slip, take it up another 1/2 turn, and so no……
Also Log each Run so you can clearly see Boost.
Are you going back to the dyno?

Tim w the 2.87 and the Gtm pulley mod I ran the 79.5 and the same belt that was old made the best numbers. With this new belt so tight you could only turn it maybe 45 degrees it still slipped a lot up Tom. You could physically see the belt flex n slip after 7200 rpm and the dyno shows the drop off clearly it's a gates belt. Not today we will not be. It's been nasty weather all day so we are heading back home. If I can get it tighter after some time and see solid boost numbers on my gauge I may be back again in the near future but for now I will just enjoy it. I know it has a lot more left.

It could be weather related, wet, Humid and cold……
If you can't get it to hold, you may want to look into this:

either way i am very pleased with today, didnt make record breaking power but i know the blower is deff capable of numbers we have never seen on our platform atleast. but most importantly the car was great. not a single issue on the dyno(except the slipping) and car put down consistent numbers time after time and jon did well over 20-30 pulls. its a 4 hr drive so untill i am 100 percent sure it is not slipping i will not return but i will work on it while i enjoy this power

Random question. High hp Vortech friends. Which belt so you use? I was on a regular gates micro V read that the mustang Vortech guys seems to almost religiously used the green back version and went n picked me up 1 same part number just HD at the end. Anyone else run them?

^^^^ I run green backs, they also cost a lot of green backs. lol
As an alternative, its the regular gates. The Gators are absolutely garbage. Id put one on to drive across country knowing boost is not going to happen....just to save my pricey green back belt for when I arrive. lol.
Ive swapped belts on the side of the road in a suit in under 15 minutes. Althought I did burn myself a bit. LOL. I keep 3 or 4 in the trunk because of the old days of belt creep still haunting me.
my belts are 91.5 to 92.5
