363whp/430wtq/32Psi-Stock Turbo.
Today I re-tuned a previous Evo X Gsr that already made 375whp/415wtq on c-16/vp Import mix on the stock turbo:https://www.evolutionm.net/forums/ev...rbo-motor.html
We just finished installing Kelford's Stage 2 cams with their dual valve springs. Arp Head Studs were also added to insure a nice sealed head at high boost. Upon Installation we also swapped in a Hallman Pro Rx MBC.
A few hours later and we hit the dyno with 32psi on 93 Octane. I personally re-tuned this car since Charlie had to go away for a few days and I am confident and happy with the results!
Some fueling is still needed to smooth out 5,600-6,400 rpm but other than that the graph is rock solid. I could have still pushed the car but It's real hot and humid in the dyno bay today. 90 degrees with 90% humidity. This car is now 10whp away from It's race gas map on the stock turbo and 93 Octane thanks to the Kelford Stage 2 Cams.
I personally don't think the Kelford Stage 2 cams are too aggressive for the stock turbo. Peak Torque comes in hard and strong at 3,800 rpm so they def. didn't add any lag to the mix. The stock turbo is just simply out of breath at this point. I'd love to see this car on a blouch 2.0 or an FP Red down the road.
Stay tuned for some track time. With these numbers on our dyno it should be dipping into the 11's with ease. Enjoy!

There is no miracle in tuning. Having the right parts and tuner will greatly help you out in the performance department. Keep in mind, this is a friends car as well so the tune is much more aggressive than it normally would be.

Wow, 315 HP at 3800 and it bulges to 363 HP at 5600 then still makes 325 HP at 6900... It looks more like a flow map for the turbo on a test bench! Since the Torque peaks at 430 @ 3800 and almost evenly tapers down to 250 @ 6900 you are likely running just about max boost and airflow for the turbo the entire rev range!
What kind of boost curve is it running, something like this?
4000 32 psi
4500 30 psi
5000 28 psi
5500 26 psi
6000 24 psi
6500 22 psi
7000 20 psi
While to many it still seems high boost to be running on pump gas, you can tune the AFR and timing to accomodate it from 4000-5000 to get the torque hit and the tapering nature of the stock turbo will keep everything else within reason above that. I would say you are pretty much maxxed out for flow through the engine with those cams in there, looks fun!

lol niceeee...how much a difference did the cams make with the sound of the car to?
Also I might come by tomorrow to pick up my parts and keep them at my house till I get the rest of the parts to retune the car.
