FP Red......565awhp/557awtq on E 85!!!!!!!!!!!!!
True. It's not really "a way around it", but from what we have seen a stroker and true twin-scroll seems to help alleviate some of it.
Best we can do thus far
It appears most of the benefits from twin scroll however are only felt on the road and not the dyno, quick spool and low end tq is only part of it, the transient boost respnse is something that can only really be accounted for on the road.
I am sure the Red responds quick!!!
Scorke
And remember with a 100mm stroke, every .5mm increase in bore is approximately 25 more cc's...so stock stroker is 2.27L, .020 overbore is 2.298 and .040 overbore is 2.324 
Who says you can't get close to 2.4 liters with a 4G63

No.
The HTA 35r, 35R, 30R all offer a considerable amount of lag compared to a stock turbo.
There is no way around the increased spool times and boost response associated with going with a bigger turbo, some might be better than others but none compare to a stock framed smaller turbo.

For those who cannot afford or justify a Full Race TS kit (most of us), the Red does seem to be a good alternative.
And the 22mm pin, 86mm off-the-shelf J&E stoker pistons only weigh one more gram than the 85.5mm (286 grams vs. 285 ).
I'm going with a .040 overbore with the Red. Who cares about cylinder wall thickness when you'll be around 500 whp. Just need E85 now

ok, pull up beside me with a 16g, green/red/blue/white whatever, 30r and see if that quicker spool makes any difference.
I'll brake boost and be at 30psi and when it's time to go it'll be all over but the cryin and if you're going from a dig I launch at 7000rpm on the 2step at 15psi, there's no respool time on shifts either.

Remember some guys that own evos actually turn and throttle steer.

Didn't say autocross at all...just turning. I put autocross third behind rally (not rallycross) and road racing in terms of the Evo's specialties. Autocross is lame compared to those anyway. In a track event, you get over an hour of track time per day...
