Turbotrix X - 377/370
^Our STi's don't have a closed deck either, they are semi-closed aluminum just like the 4b11. Plus, semi closed decks can still hold a lot of power. I've seen STi's with 6-700 on the stock block with just upgraded internals. The evo X would've been the better buy I think, but either way I hope you enjoy your sti. BTW Keith or Jeff, what was the fix for hitting fuel cut? I am still very curious to see dyno graphs, and when you guys post them, could you put up the boost curves and A/F curves to show what they are doing now? Thanks guys, and keep up the great work.
Personally I can't wait to see how much further the stock clutch will last. IIRC, previous gen stock clutches gave out around 400-440 whp (dynojet).

I've done a ton of research on this forum to learn about the vendors so I can decide who to work with when I finally order my X.
I've noticed the same thing you two mentioned. Several threads about these guys where the consumer has ridiculously high numbers (almost too good to believe) and then timeslips that can't stand up to the claimed HP gains or the owner won't post timeslips. I don't know who to believe in those situations, but it does raise some level of doubt for me.
If TurboTrix is willing to make a guarantee of these numbers, than I'm all for it. Until then we'll have to see if these are legit once the car is on a track and they post timeslips.
Also, how safe/reliable is the car at this power level?

this is from my own experience with the shop i don't know about others.
Turbotrix, keep up the good work, i am following this thread very closely

One guy got 400+whp on stock turbo and bolt ons at 25psi on pump gas on their dyno.

My comment was directed towards the guy who said that he wasn't sure how much power the stock block on the 4b11 could hold being a semi closed deck. This was not a question of the internals, but of the block itself. I too am curious as to what the strength of the internals are just as much as you are. BTW, not trying to argue, just clarifying what I said. Oh, and Keith or Jeff, let's see these syno graphs and boost curves/A/F ratios. You guys are killing me with the anticipation. I can't wait to see the results of the 3.5 in exhaist that you mentioned in the AMS downpipe thread. Thanks.

Here's the latest graph from today and a video.

The stock ecu has been a headache to deal with. We spent the last two days playing with boost levels, different blow off valves, fuel pumps, a/f ratios, higher octane fuels and a few other things. The ecu is a lot more sophistacated than previous years and can be quite tempermental. It's quick to shut things down if it sees something it doesn't like so keeping the ecu "happy" has been a chore. This will be easy when our tuning software arives but for now we have to do it the hard way.

I'm really liking that BOV. Sounds like a SSQ! That's really impressive without any real tuning software. I can't wait to talk to you guys about mine! There's no doubt I'll be wanting this on my car, you guys are really doing a phenomenal job. Let's get some pricing info!

If there was a track that was open we'd be there tonight. We want to know what it will run as much as anobody else.
All we're doing is posting results as we get them. We're not ready to offer anything to the general public for the X till we do further testing.
With 2 shop cars now we have the ability to test everything twice to back up our data. We're going to "lean on" the white car to see what the fuel system, turbo and the motor can handle. The other car is getting the basic bolt-ons for now.
I'll have a few run videos up later today.
