I am thinking about having East Coast Supercharging install a pulley and tune. They have a stage 2 package with 2.3" WeaponX pulley. I already have an AFE CAI installed. They claim 650HP/660TRQ at the wheels. Not bad for $2k! Has anyone gone that route or something similar? Any increase in coolant and oil temps? Noticeable difference when on throttle?

I'm close by and in the same boat. Interested to see the results

DOUG @ ECS

This is a very common build for us, as in literally a couple per week, if you like I can post up dozens of dyno sheets for you or stop on down and take a ride in my 19 with basically the same mods. My car has dipped into the 9's at the drag strip, lifts the stock front tires off the line, and can walk a stock ZR1 on the road course. No temps issues on or off track and I have put 14k miles on it this year.

Thanks for your interest in our services!

Doug, I will take you up on your offer to take a ride in your Z and feel the difference. Will the cold temps, I would think putting power down won't be so easy. Let's plan something when the weather warms up. Mike

What sort of time frame are you looking at from drop off to pick up, specifically for this package? I'm heading the beach in July this year and I'm wondering if I could drop it off on the way and pick up on the way back through. Thanks in advance!

Got a quote from Chris for $2800. Is it just because of the intake or?

c7gsmike

Thanks for sharing. He quoted me $2k as I already have the AFE installed on my Z.

DOUG @ ECS

We'll be here when you're ready.

it's usually a day job, if we have it first thing in the morning, you can come pick it up at the end of the day.

Are you sure about this Doug?

I have never seen a 2.3 pulley, CAI and tuneZ06 pull a stock ZR1.
650rwp generally wont pull a stock ZR1.

DOUG @ ECS

My mods are an 18% balancer (which is very close to a 2.3 upper, 190-195KPA) drop in air filter, front AFE pipes, and a flex fuel sensor

I have haltech intake on mine 2015 A8, but what would the best next mod be a flex fuel or a pulley swap?

DOUG @ ECS

Pulley swap, a 15 would need a low side pump to use E85.

Buddy A

Doug, would the same be true with Kooks headers added to that scenario? Pulley work on a 2015 with Halltech and Kooks without fuel issues?

DOUG @ ECS

Headers will work too, I just finished a 16 that had a 15% lower, ported blower, TB, CAI, low side, and headers. The ported blower with the 15% makes a little more boost than a 2.30 upper and no port work. That setup was basically maxed out at just under 700. Keep in mind that's dynoing now when the DA is -2500, it would probably make 670-680 in the summertime. From there we added meth injection, which brought all the numbers fuel-wise together with it not even being on very high. That made 780, from there we did some E tuning which brought it 856 but it was just starting to drop below the requested high side numbers, but tolerable.

Just a reference for you, there are other ways to get the fueling, some people do not like meth, but it is drastically more expensive once you do a cam swap, pump, injectors, and so on. I personally do not mind meth to a point, keeps the engine clean, IAT's down, you just have to do a little maintenance every few years.

Thank you flex fuel was the missing ingredient.
You are probably closer to 700 rwhp.

Good info.

I have an AFE CAI, 2.17 Weapon-X pulley and ECS tune
648 to the wheels. Not 650 but close :-)
LOVE it!

I am wanting to know if the stock fuel system would support a Halltech, headers, and a lower pulley? And if so, which pulley?
Thanks

DOUG @ ECS

Correct, just under 700, once it pulled 708, but usually 690 area. I went threw a tank of E85 that day and switched back to 93 for a few laps and at that point I couldn't walk away from him anymore which makes sense numbers wise.

DOUG @ ECS

It will, an 18% or a 2.3 upper will make about the same boost level so we usually do the upper due to price.
