Dom2 on pump+meth = 200WHP over stock!

I think 8000 rpm limit seems to be fine assuming no knock on a solid tune. So as a summary:
~ 375 whp safe Pump Gas tune
~ 395 whp aggressive Pump Gas tune
~ 420 whp with Meth
Boost levels were 28 psi tapering to 24 psi?
Have you guys tried to remove some of the taper yet and what WGA are you using? At 4000 RPM I'm getting 26.5 psi tapering to 25 psi by 7000, then it tapers to 23 psi by 8000 even though it continues to build HP in that range. I'm still going to test preloading the Forge WGA with 4-5 turns and see if the minimum boost goes up and reduces my top end taper at all.
Nice results, and it should only get better with FMIC and Cams!

The wastegate actuator i useing came with the dominator turbo from buschur at 29psi it drops to 25psi by 8k but power still keeps going while the boost drops off.Hiboost how did that intake manifold work for you?

My friend went on vacation so he will finish the intake manifold experiment when he gets back. I've got some solid baseline numbers now so we should see a good before and after. Then I can tune it a bit and dial in mivec a bit more for max power. I may also test a 100 octane unleaded tune for fun. I'm still leaning towards cosworth cams after seeing the great results that Buschur had with improving low end torque as well as top end horsepower. I'm concerned that the Kelford stage 2's wouldn't increase the top end enough to warrant the loss down low, or off boost for that matter.

On the following Setup:
Dominator2
ETS O2Housing/Downpipe
Invidia Q300
Hi Flow Race Cat
FIC 950 Injectors
Cosworth MX1 Cams
Walbro Pump
WORKS tuning
I hit 450WHP / 360Tq on E85. Would have made more but the car was running out of fuel.
Car hits 20psi by 3000, 27.5psi by 4500.
Feels a little laggy on the road but not too bad. Will see if I can post some graphs later.

This was on a dynapack dyno.

I am not sure how much lag would be added with your setup though...

We are making peak torque at 3,800rpm on a stock 10 turbo at 32 psi with the kelford stage 2 cams+full bolt-ons. 93 Octane. (4th gear pull)

For pump gas it appears the Dom2 is the best bet for most people and it takes well to basic bolt on mods or a car with the works done to it.

I'm still amazed at that stock turbo setup on those cams! It's so hard to compare cams on cars without only changing one variable. Nobody wants to install cosworth cams on a Dom2/ FP red car, run multiple dyno tests and tune them... then rip them out and install stage 2 Kelfords and see how they compare. That's just way too much work!

Guys, I realize this thread is from August, but felt compelled to post now that we are an official vendor/sponsor of EvoM now. I wasn't able to post previously about the car but if there are any questions I am happy to help now. This thread had a lot of interest before.
Just let us know.

Ya well i think i got a defected Dom 2 i mean it makes great power but it surgs really bad a low to mid rpms for 3rd 4th and 5th gear and its soo annoying. If cams dont fix it think i am throwing this turbo in the trash and getting something else
