I originally had my car at Vengeance Racing. Great shop btw. My car is a 2018 A10. It made 550/560 bone stack in 90+ degree heat.... It was there in August. We did there CAI, 9.1 lower pulley, Kook's 2" headers with green cats and flex fuel. It made 650/680 on 93 octane and 685/720 with 45% E. The stock fuel system can definitely keep up with that power output.

Not to hijack the thread further, but for informational purposes I spoke at length with VR before going with the 18% lower. Was never told meth was recommended or needed, in fact meth was suggested at the next level of mods, which would be heads and a cam. We have started to get some warm humid days down here in Georgia and I have not felt timing be pulled / sudden loss of power, and I track a number of parameters on my aero force gauges. So, all I can add is that my experience has not been as has been suggested.

Ron and the guys worked some real magic. They swapped blowers with a Kong blower and retuned everything to tweak things. 670rwhp and 659tq. The day was a lot cooler; in the mid 70's so that helped. Fwiw the original setup that only made 629rwhp on a 95* day made 640rwhp on a mid 70's day. What everyone says about heat soak on these motors is no joke.

The new blower on the same 2.3 griptec was making 13+ lbs of boost. Most of the lost power was in the limited boost. I'm very happy and can't wait to get the car. I'll post dyno graphs later. I am looking forward to the big difference in tq. which is 102 more than stock and 28 more than the first iteration!

Wow!!! That’s more like it. Congrats!!!

What ported blower did you originally run? I dropped off my 17 Z07 yesterday. I installed a Kong Ported Blower, NW 103mm TB, Halltec Stinger CAI and dropped off a set of Billy Boat Headers and catted X-Pipe and IW 18% Lower Balancer/Pulley. I am expecting around 650ish rwhp plus or minus. 670 is a very solid number for your mods. If mine makes your kind of numbers, I will be very happy!! Congrats!!

Made 625 rwhp and 647 torque . The car feels very strong with 100 ft lbs more of torque across the power band it is very noticeable! It feels like a different car! I had them measure in SAE not STD

The baseline was 554/540 I attached before and after Dyno.

Vengeance did a fantastic job on the tune drives like stock with better everything !

Attachment 986737

So you gained over 70 hp with just pulley, headers and CAI. Not bad!!

They gave you the blower or did you spend another 5k for the new found gains?

So you put down 670 with the Kong ported blower and the same 2.3 pulley? + 30 whp by just replacing for another ported blower and tune? Damn...

Yep very happy with the results also the 100 ft lbs runs great

Car is back home. Looks good. Sounds great and pulls hard. Very happy with vengeance. I ended right where I hoped I would and the performance is great. Weapon x heat exchangers next to keep things cool in the Alabama heat, then I am done. I couldn't ask for better customer service than what Ron offered. Vengeance was a good choice, glad they are close.

I'm sure the car is a bullet now! This thread has helped me with my decision on which route I'll be going. Please keep us updated on how the 2.3 pulley performs.

[2out2sea]

The griptec looks the business, but apparently more boost and less potential belt slip can be had with a lower pulley. Since I'm not doing any further mods the 2.3 is perfect.
