Replaced crawford AOS with an IAG Comp unit, added a Radium surge tank w/ Walboro 400, really nothing power based just to take care of some other minor issues.

Red line is me, green line is a stage 2 2013 STI

Yeah, I was talking to Clark Turner about that while he was out here.... just never going to happen for us. Another 80whp would be nuts.

Now, I could always jump up to the 7163 and run antilag though.. that I can do!

What psi are you running? Whats anti-lag? Could your engine handle a 7163?

I'm running 24psi down to 22psi at redline.

Anti lag keeps the turbo spooled when you let off the gas, but at the cost of possibly damaging exhaust components.

I think the motor could handle it for a while, if it exploded.... that would be a great reason to drop a stronger one in there wouldn't it?

What ecu are you running? Without a standalone you aren't getting real anti-lag.

Cobb AP, I don't believe it will be true anti-lag, no, but if it happens I will do a post on it. Either way I will probably get a tune for the 7163 and the IRL .64ar housing just so I can swap if I want to.

This is what the ALS would be:

That is not true anti lag either. True anti-lag has two components:
When you engage anti-lag you need a way to allow extra air to enter the engine to assist in spooling the turbo. For throttle cable cars you would used a TB bypass solenoid. For E-throttle cars you can used a second tps map that hold the throttle plate open further. Both of these causes would cause rpm to go up so you need rotational idle which basically cuts cylinders as needed to maintain idle speed.
What Clark was showing there looks no different than ignition based launch control/2-step which is more often than not, incorrectly called anti-lag.

There is a system in place to hold the throttle plate open and programming associated with the system. It's not my place to go into detail, especially since I haven't had any first had experience with it.

I can tell you from personal experience though, that video doesn't sound anything like my LC/2-Step, nor does my LC/2-Step build that much boost, nor does it work with my foot off the throttle.

It will be a fun thing to test at least =p

PS: Lets not derail this into a true ALS vs whatever conversation. Obviously this isn't a rally car with an expansion chamber and separate air metering system, but if it helps me get around corners faster and keep the boost up I'm interested, whatever it is.

Sorry about that. Interested to see the results.

You can also do a cyclic mis-fire in which a cylinder skips combustion for a cycle, being specifically a 'bypass' for air to pump into the exhaust. Usually accompanied by a fuel rich, exhaust.

And yes, I know it was an old bump, sorry. Was looking up some 6758 data and found this thread.

Any update on the car? Is ethanol any more prevalent out in Hawaii now? I know stateside it keeps becoming more and more available.

Any options for methanol/alcohol injection?

Lots of updates but little time to post about them!

- Changed the 6758 for a 6258 and kept the IRL hotside
- Decent amount of weight savings from small stuff
- Consistently beating a 600whp GTR at AutoX

Good times.

Also, found a source for ethanol which Iím going to use by the end of the year - itís potent stuff:



Here is the 6258 dyno:



I was dumb taking the photo, but thatís 300wtq @ 2700rpm - So Iím happy.

The ethanol is going to be a whole new trip, kind of excited.

What's been your overall experience with the move from 6758 to a 6258? Miss any of the extra power/torque, or does the earlier spool make up for it all?

So what was the difference in the two graphs?

And, can you get the scaling corrected, the dyno graph is very difficult to read as it sits with the hp and torque scaling being different. At least show the hp scale if they cant correct it.

The red is high boost, at 26psi, the other is low boost, at 22psi.

I likely can't... the facilities out here are garbage to begin with and I'm trying to fiddle with the dyno computer myself for the most part.

For my purposes, the earlier spool certainly makes up for it. I can dig out of slow corners really hard now, and that's what I needed.

Nice. Good info. I'm considering turbo's for my new setup and this helps.
