Just as the title says.

I know LJ has gone 139 mph with it. I've made 680 rwhp (auto) with it, which is about 850 fwhp and good for ~142 mph.

I'm just wondering if it's holding me back.

I'd move to a bigger core ASAP. Have you measured inlet temps and pressure drop across it? On a 90 degree night the other day we were seeing inlet temps at 65-70 with a T88 @ 20 psi on a buddies setup with a goodly sized cooler and ice in the tank. If you arn't seeing below ambient with ice in it, I'd say it's too small.

My iat's were 170 @12 psi (putting ice in the little stock reservoir). I gotta believe yours must be through the roof. Is yours modified in any way like bigger pump and or heat exchanger? I know RMCR was looking at cutting the inlet side to modify it for a larger intake tube. What blower, YSi? I did loose 3 lbs. boost going to a FMIC but got 2 back putting the MAF on the pressure side.

I'm actually running a single PT-76 GTS turbo at 19 psi with Meth injection. I'm not that worried about cooling as the Meth really gets the job done there, even with a marginal intercooler. I guess I'm more worried about pressure drop.

BTW, I've upgraded the aftercooler by using a 5 gallon reservoir in the trunk. Otherwise, the aftercooler kit is stock. I know that after 5 dyno pulls the water was barely warm at all.
