What else do you recommend? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I'm getting ready to do some more upgrades to my ZL1.

I currently have a CAI intake, Kooks headers and catless mids, a catch can, and a tune.

I am installing:
2.5 upper pulley with solid isolator
10% lower pulley with ATI balancer
ID850 injectors
HD belt

Do you recommend installing anything else to help get the most out of these parts? I'm currently at 535whp and I'm hoping to be over 600whp.

I am also on the fence if I want a cam or not. Was thinking the BTR stage 2. If I do that, I was thinking methanol injection to help me get closer to 700whp.

What do you guys think?

A cam will really wake up the LSA........The meth injection will also help and you should look into a Rotofab tank for extra cooling......

Probably need a boost a pump with those mods or else a fuel system upgrade. Just to be safe.

That is going to be a lot a boost with a 2.5 upper and a 10% lower without a cam/ported heads! For example with just my 2.50 upper mine is making 15PSI of boost (bolt-on car)

I'd recommend a heat exchanger and expansion tank as well or else you're just going to be huffing hot air. I would recommend just the 2.50 upper until you put a cam in it (then do the lower too).

Do you have headers and no cats? That reduced my boost significantly. It's like 7psi right now.

You think I'll need it for just pulley upgrades?

I have kooks long tubes with cats, before I installed the 2.50 metco upper I was also at 7PSI.

I would assume that I am going to make a tad less boost since I have no cats. I'm just trying to see if upgrading the HX is a must or just a preference. I would be tracking the car a lot. Maybe here or there. And it's not my daily driver. Just driving around, not getting into boost, should be just like it is now.

I did not do a before and after IAT2 log attempt, I would at minimum if you didn't do the HX to at least get the rotofab expansion tank as a cheap alternative to increase the amount of fluid capacity circulating in the factory HX. Heat soak is even worse now with double the boost.

with an upper and lower pulley, I would definitely do some fueling upgrade. Just read all the "WTF Happened" threads and it seems like fuel starvation is the most common.

Yeah, I might just give JDP and JRE a call to see what they recommend.
