Yep the valves stayed open too late so the question is what Cam was in place as the lift and duration has as much to do with it as the cam timing. That also appears to be the RMW head so would think somebody was trying to move the torque curve down but if they did indeed use a cam gear who timed it? With the way they broke in next door cylinders would have thought a hand turn would have caught it before the engine was started up. I thought Jan sold them at one time.
I would be surprised if somebody that paid the money for a RMW head would be running a 250 duration Dominator Cam but rather something more like a 264 or 288 duration. Those last two would take advantage of the bigger vales. The stock oem cam has a 244 duration so the Dominator is not that aggressive relative to duration. While on cams the other thing that should be noted is that if the cam "shaft" is standard, then anything with a lift of 0.400 or higher will contact the spark plug tube. Last as the RMW cams are Newman cams, anybody that does business with them can most likely get all the information along with where the duration start point is.
So the last three posts “guessing “ what went wrong to what happened to the head I posted are comple wrong. This is why you can’t believe everything you read on the internet or 100% believe from a vendor. This was an RMW Head that was abused and the owner never he never checked his oil.
From the comments above it would be logical to assume that the pictures provided were there to collaborate the comments.
Looking forward to seeing that.. like Project Binky, love seeing stuff get made. Agreed... that would be classified as a bad day. I actually had a very expensive one end up like that on my 93M5. Turned out the head shop made a mistake and decked the block (thought it was for a different customer) unknown to me. I didn't to a pinch test as it wasn't supposed to be. Amazingly I got 17K miles out of it... but one night was running it pretty hard when all of a sudden it let go. Was like 12am and I was stuck for over 2 hours getting a tow truck. Expensive mistake.
A peck on the cheek is fine, but full on french is going to cause problems.............wait, were we talking about cars?
You always have to be careful with peck's on the cheeks. That could be interpreted as inappropriate advancement which will come back to haunt you over time.
Sorry, haven't been able to post for a while... The above is almost exactly what I experienced with the addition of the Cam Gear on a stock cam with an RMW BVH and the Sprintex. I got a total torque increase of about 8 ft/lb, but most importantly it started about 700-1000 rpm lower in the range, and made the butt dyno and overall driving experience much more enjoyable. I was so happy with the results I got another one when I bought this Cam from Thmpr as well, I just can't see using a BVH without one to supplement its natural power curve. As far as comparing heads, I can only give you a short term opinion since I only used this Head with my Sprintex for 7k miles. Honestly from what I could feel, they're both very evenly matched, and the car felt almost exactly the same. The only place I think i may give the nod to the TPR2rt is in the very upper end of the RPM with boost in excess of 18 psi. But... I really believe the reason for this is the match porting, and if you're not going to be pushing boost over 18-19 psi, the match porting just isn't needed, and the performance of both Heads are near identical as far as seat of the pants is concerned. The only other issue will of course be longevity, I've only got 12k on this Head and was able to get 125k "hard" miles out of the RMW. So now only time will tell
