This is a 2015 Z06 M7

Mods are:
15% OD lower pulley
Kooks 2" headers and X pipe with HF cats
Cartek ported TB
AFE CAI


Here are the dyno numbers before and after the mods on 93 octane pump gas. Next mod is a larger heat exchanger.

C6-LS2-MN6

We installed and tuned the car, the stock fuel system is good to about 680 RWHP on 92 or 93 pump. Not sure why your installer doesn't want o go over 10% OD.

What does that 70 horsepower increase cost, installed and tuned and out the door?

3 Z06ZR1

Good numbers
It does show how the 1.7 dies off.
This 2015 Z06 m7 with only 2 inch headers, halltech, PTB and 2300 heartbeat
Looking at the 2300 here it gains 75 rwhp from 5250 to 6500 where the 1.7 was dead gaining only maybe 10 hp at 6500. Plus the 1.7 is spinning much faster.
This dyno reads very low on the RWTQ rwtq feels very strong

Thank you. I would get a dyno tune with mods like this.

Send me an email to jhormilla@cartek.net and I will send you a quote.

Thank you. I think there is more left in it with the stock blower, the heat exchanger isn't doing much on the dyno with just a fan in front of the car, the fan has a wind speed of 10 to 15 mph, I think we can go to the 18% lower pulley and a larger heat exchanger and coolant tank and on 93 pump we can get to about 680 rwhp.

Unfortunately E85 is hard to find in NJ

ATI damper and 15% OD pulley

I made 624hp/667tq with similar mods (low reading dyno and car was still hot):

2" Texas Speed longtubes
Halltech CAI
2.31 Upper pulley

Considering doing a lower pulley but probably going to wait until I get a meth kit as well. E85 isn't readily available in my area.

Nice, I was looking at the same setup but with Cats, due to being in NY. Any issues with cooling using the 15%. Im thinking the same pulley.


Thanks

tekhombre

Nice!

tekhombre

I haven't experienced any cooling issues with the 15% or the 18% OD pulleys.

Not sure what you are referring to about cooling issues unless you mean going into limp mode. My manifold temp. got up to 169* during a pass with the stock pulleys and my fan running at 75% via my HP Tuner on an 83* ambient day. I feel I had a cooling issue when my timing reduced causing a loss of power.
