It's the stuff dreams are made of. The old HR turbo makes a great torque curve too -- so it really pulls hard from 3k or so. At 22psi, the steering gets very light.

Mine did the same thing and I ran it 3 track events until the WFHG just blew entirely. So far, adding the O-ringing has prevented a recurrence at 18psi.

Update: I pulled the intake off tonight, and checked the top row of nuts. I put a click and beam style torque wrench on the nuts and pulled -- the nuts did not budge at 65 ft lbs with either wrench. I loosened a few just a tad and retightened, and they did not move beyond where they were. I'll pull the cam tower this weekend. If the wet nuts don't budge either, I am torn between (a) tightening them up to 80 or 90 ft lbs, or (b) pulling the head, checking for flatness and, if flat, trying a set of factory studs. I'll be assembling and installing a 3L over the next few months (pistons ariving next week), so if the deck is not flat and I need to pull the motor, I am not likely to reinstall it -- which has me leaning toward giving higher torque a try.

I also snapped off the blue radiator plug while draining the coolant. Anyone know if Parts Heaven has them on the shelf? If not, I may need to summons the mighty power of Rennlist to score a plug over the weekend.

1.5 bar cap. Any lower and I have 'spitting' problems at tha reack!

Tom, since you have the intake off it may be worth it to take a torque wrench the the head nuts that are exposed (the ones not buried under the cam tower). Just check to see if they are still at the same torque.

I tried that, and [edit] none of them budged at 65 ft. lbs. (Or 70 ft. lbs. for that matter)

Anyone know where I can get a precision straight edge locally?

Ok, 1.5 bar. I stand corrected. Thanks Chris.

I know you're all on the edge of your seats, so here's my update. I pulled the cam tower this morning. Although the nuts under the cam tower all clicked-off with the wrench set at spec, when I backed them off a tiny bit (say 5 degrees) and re-torqued, they clearly turned further tight (say 15-20 degrees more) in order to get back to spec. I'm hoping I just didn't wait long enough before re-torquing last time, and the HG compressed a bit more. I'm going to tighten them a bit beyond 65 ft lbs too. Here's to hoping!
