We've got Sick Seconds 2.0, the world's quickest street car, at the PRO Superstar Shootout Presented By SCAG Power Equipment at Bradenton Motorsports Park. We were going to match race Brett LaSala but unfortunately that didn't pan out so we were on our own...but somehow we found a way to lose our own match race! The motor dropped a valve mid-track and it was carnage inside. After Sick Week didn't go to plan and now this it sucks...just when we were getting somewhere...

[@randallbergen7065]

Having been the cylinder head guy on a nitro car I can tell you the only thing that prevents the type of failure you experienced is constant service. If the valves had been removed and checked regularly they would have told you prior to this happening. The easiest way is to check over all height. If the valve is getting longer the head is being stretched. A visual of the backside of the valve may give you an indication but an increase in length tells you the head of the valve is going to come off. It is up to you to determine the amount of growth you will accept prior to replacement. I once threw away four brand new inconel exhaust valves that had one pass on them. The boss wanted to try a little more seat pressure and the swirl on the backside of the valve was visually straighter. If my memory serves me, those valves had stretched 0.100 to 0.125", and that was from one pass. Don't get me started on head droop on the exhaust valves that remained open when the engine stopped turning.

Well, you won the trophy for "most carnage from a dropped valve", in the contest between you and Steve !

But "that's racin'", right ?!!

[@jdoe9518]

The failures were completely different. A broken retainer takes spring pressure away allowing piston to valve contact. Can be lucky with amount of damage. A broken valve stem is going to eat a piston and combustion chamber at a minimum every time

​@@PennyTrayshun-u8u My observation as a couch potato is that there is a bit of a difference in maintenance schedules between the guys running SMX on these drag and drives and guys running similar HP engines. At a certain level teams seem to start considering much of the valvetrain as consumables. I think Steve would be doing himself a big favor if he pushed similar maintenance schedules for these SMX engines. Valves, springs, retainers after every drag week event seems like cheap insurance and would almost certainly prevent a lot of the failures we've seen.

[@jasonm3109]

@@PennyTrayshun-u8u a proline hemi needs the rods changed after 26 passes. If you put it on the chip, you change all the valves, springs, retainers, and rods. It's not the fault of the SMX that Tom put it on the chip multiple times and kept sending it. If everyone running the SMX maintained them like a proline, you wouldn't be having these issues. Even the prolines can grenade for no reason. If you take the amount of miles these go on the street and still make that hp and how many of them live for the entire week, it's pretty damn amazing.

Hey Tom....quick question: since the Radial guys and Big tire slick guys need 2 different track preps, why don't the Sick events have 1 side of the track prepped for Radial tire and tge other side prepped for the big tire slick cars? I ask because the construction of the tires is so different and the slick guys can't build their needed tire speed to get down the track...it makes sense.
