Just installed a Ripatuned Incognito lower pulley and I had it pinned. I am considering a 2.95 Metco upper pulley with Demon Injectors and a boost-a-pump. I am currently have a JLT intake, Stainless Works mid pipes, and running straight 100 octane.
Thank you in advance.

No need to upgrade pumps, your set up is fine. I would consider adding blower spacer and blanket along with a 180 thermostat before tuning.

I actually just installed a 180 thermostat and I have the spacers and thermal blanket coming today. Thank you for your help.

Use a good tuner and you'll be really happy with the results...

Will I be able to use smaller fuel injectors with the 2.85 and Ripatuned incognito pulley? I am able to get a crazy good deal on custom fuel injectors. The only downside is the biggest they go is 880cc.

What if decided to run a 2.95 or 3.10 pulley? Would 880cc be good enough to operate safely?

I know you want to limit your spending but you could just add a BAP for added assurance. They don’t cost much and will give you more room for growth when the skinny pedal no longer creates the same excitement it once did.

I would think 880's would suffice... Just keep and eye on fuel starvation and duty cycle.

Just to be clear, you think the 880cc injectors would work safely with the 2.85 pulley? Or better with the 2.95 or 310 pulley? Thank you.

If you run the 2.85 use a BAP for 2.95 and above you should be fine..

Sounds like the 2.95 is the way to go for me. It wouldn’t matter if I am running 100 octane, right? The 880cc injectors will be fine? I really appreciate your time and patience in answering my questions.

Does anyone know what belt size I need for a Metco 2.85 or 2.95 pulley? I’ve contacted Metco and they aren’t familiar with the Ripatuned Incognito lower pulley I have and cannot give me a recommendation on the belt size. Thank you!

You have a lower? The 2.85 and 2.95 are uppers. The lower is usually 9 or 10% overdrive.

I’d like to get an opinion on something...Will I need a boost-a-pump and an idler pulley if I went with a 2.95 upper pulley and the Ripatuned incognito lower pulley (6%)? I will be using 100 octane and 1000cc fuel injectors? A vendor is saying that I will need them for this set up. I’m just making sure I that don’t pay for anything I don’t really need. Thank you.
