I did some more driving around today to test out my brakes again, and still nothing. But, i saw that I hit full boost a little after 42500rpm's. I say afterwards because that's when it starts to pick up (at 4250rpm's), and it's hard to look at 3 guages, the tach...oh, and the road at the same time. I'll get a log as soon as I get my brakes figured out, I promise.
It's really different going from a smaller turbo that you can just barely give it gas to get the car to start rolling foreward whereas this one you have to give it quite a bit of gas. The extra lag is completely worth the top end i gain though.
Do you plan on using a divided runner t3 manifold?
My plans were to make a tubular undivided t3 manifold, but i have been toying with the idea of making a divided manifold. I hesitate to build a divided t3 manifold because I'm not sure the WH1C will make the power i want. Ultimately i would like to try and reach 500whp on pump gas, but i know it will be very difficult to reach that goal, and im quite sure the wh1c is too small for that. I don't have the money to buy a bigger turbo at the moment, so i have been thinking of putting the wh1c on and maxing it out before i go any bigger. Do you think the HX40 would be able to make 500whp on pump gas? This is a brief and uncomplete list of what my setup will be.
2.3 stroker
Ported head, 1mm oversize valves, FP3x cams, SI duals...
aem ems, 880cc injectors, +all other fuel mods.
big FMIC + full intake and exhaust mods...
With this setup i feel like the wh1c would be really holding back the cars potential. What do you guys think?

The HX40 Pro is a monster. I'll be dynoing this weekend. Hopefully I'll have some nice results.

Don't look at the h1c as holding your setup back. Look at your setup as capable of extracting every ounce out of the h1c. Look at Curt Brown's car. . . You need an SMIM.
The wh1c has a 54mm inducer and a turbine larger than a t3 stage3. The divided runner set up may get you to that level. The mitsu bolton bep housing with the hx35 has put down 500whp. So it's not likely the turbine of the h1c is a restriction as a bolton.
It's not that hard/expensive to switch to a t4 hx40/h1e. Also you can pick up a t3 .70 a/r BEP housing for an hx40/h1e and run a divided runner manifold with zero negative effects.

I like that mentality! I am planning on getting a SMIM, just can't afford it quite yet. I should see how much horsepower it is possible to get from a wh1c. At that point if i still want more, maybe a HX-40 pro would be a good choice. I only see 2 or 3 guys that have dyno results posted using holsets, and i think it is about time to see some people make it onto the first or second page of the dyno results. I certianly plan to, but it will be awhile before i get my car all done. I really appreciate all the advice, thanks guys!
If that guy a page or so back is still looking for a Holset setup here is mine I am doing away with. And I can answer any questions you have, made 418whp and 389ft/lbs
I drove a friends 1g yesterday with an hx-35 internally gated like mine, mitsu bolt on housing, stock intake mani, all stock internals, FMIC and supporting mods..oh and nitrous. I drove it and it took until a little before redline to get that thing to spool up. It sucked driving. He said that with nitrous, it's a whole new ballgame, which is understandable. But I couldn't believe how much lag there was on that compared to my car with the h1e.

Just finished mine, not as easy as I thought it would be. After final welding took it to a local machine shop to have the flange flatened and they shaved about a half inch off. So I'm going to weld another flange on and bolt it down this time to keep it flat. Had everything glass beaded to which turned out good, painting it with high temp 2000 deg ceramic paint lastly. I don't know if it was worth all the trouble, maybe should have just bought a manifold. Had to relocate alot of shit to make it work and still have to fab up a down pipe.
No. Kraka said that your reply 'wasn't the answer he was looking for'. . . I'm saying that the spool speed or torque curve may suprise him. You'll just have to run it and tell us.

Maglin's spooled to 32 psi by 3800rpms!!! Several others reported at least as fast a spool. So it's at least plausable there's an issue. Boost leak, preturbo exhaust leak, wastegate issue, bigger than 272 cams, or cam timing issues. Or his tune could even have an impact on spool. Considering the h1c turbine wheel is practically identical to the hx35, I consider your setup and my setup proof enough that his has an issue.
