I'm installing rip a tune sleeve and already have 2.85 upper with stock tensioner . Is anyone running this setup and can help a guy out with belt size?I know I can buy the adjustable tensioner but would rather save the money abd just get the correct belt size. Thanks

Best bet would be to contact Steve Ripa. I'm sure he has the proper size available.

I am currently installing the 2.85 and ripa lower FIC1000 injectors with tune of course.
What boost am I to expect from this setup?
What fuel do you use 93+, E85, additives…?
Any tips and or pointers would be appreciated I am not too deep into this build can change if it’s not recommended setup. Thank you.

You should see about 15-16psi. The 93 octane should be fine. If you wanna do E85, you might want to consider a dual fuel pump & FIC1200 or ID1300 injectors. Your setup now should be fine though. If you are interested in doing E85, I have a set of ID1300’s that I’ll be putting up for sale soon.

I am 16ft above sea level here in Jacksonville Florida 93 octane E85 is pretty much available everywhere I am not really ready to step up to E85 yet, baby steps, will probably throw on a BAP for same added insurance. Thank you for your guidance.

I have also heard that but knowing it for fact I dont and I also dont believe everything I read on the internet....lol But I do know that at around 5300rpm mine's is bleeding off boost for some reason.I can see it on the logs but cant find the reason yet.

You are right, there is a lot of false information on the internet, is there a safety programmed into the tune to bleed off boost, just asking?

that I'm not sure of but when Demon Performance tunes it I'll know....It might have something to with the bypass valve's releasing boost when it's to much for the engine.Just dont know that the reason I'm having it retuned.But I think your right it releasing boost for safety trying to protect the engine

In looking over one of your logs your injector duty cycle is hitting 85%, at 90% the PCM will open the bypass valve to bleed boost. Be VERY careful with boost over 17 psi on 93. You logs also show STKR and the tune looks like it can reach 14 degrees if timing. 14 degrees of timing and 17+ lbs of boost = detonation on 93 no doubt. The VP Octanium Unleaded will get your octane up high enough for 14+17-18 but continued and constant use of it at the level needed, 1 Qt in 15 gallons is going to do a number on your exhaust valves and seats. I know from 2 years of doing such what it nets. If E85 is right close to you get on it ASAP before you hurt your engine to where it has to come out for repair. It only takes one bad detonation event to ruin ring sealing then increasing blow by compounds itself afterwards to a catostophic event.

I run only 93 I dont think I have enough injector for e-85....but with the 2.85 and incognito I'm seeing 17lbs. and I also use vp unleaded additive.
Be careful running any octane boosters, it wreaks havoc on exhaust valves and the spark plugs really fast.

Mike I do have e-85 close to me and would run e-85 but I would have to change out the Injectors correct?And I'm going to e-85 I would need to be tuned for it.

I'm just throwing this out there...I wonder in my logs would the reset all adaptive's keep the fuel trims from being normal or would they should be it the car isn't driven long enough?I always reset after doing any change in tune.And just a short drive down the road might not be enough time?

Yes, from the logs on gasoline your injectors look too small for E85. You need ID1050’s or FIC1200’s minimum and a dual 285 fuel pump set up. You mention gong for a tune in near future already, mine as well spend the money only once and tune it for E85, especially at the boost level you want to make. A 2.85 at sea level is already close to max for pump gas before even adding any kind of overdrive lower pulley.
Resetting adaptive should be done after a tune reload but WOT is going to follow the wide band O2 sensors to follow set lamda setting in the tune. Yours at .81 is way too rich for gasoline even at WOT.
