If I post a video of my car from 3 different angles can I call it consistent

 

You posted ONE video of a car making ONE pass that was quick. Three camera angles from ONE pass. The car is not consistent or reliable, that is a single fast pass from three camera angles.

Like I said, such EVO does not exist.

 

Jeff Bush's car runs 8's consistently....

oh wait... that's an auto.

 

My luck ran out, well that's not right cause I've not had any luck.....

Got the car all finished up today and tried to start it, no compression. I figured it was hurt after the engine locked up from the converter bolt getting lodged between the flexplate and block.

I'm not sure what is damaged inside but there is no compression at all. I have to decide if I'm going to just pull the head and take a look or pull the engine. I don't want to do either, going to take me a few days to get motivated.

Bottom line is, no track Friday the way it looks right now.

 

ouch. I know a guy who sells Evo engines in Wakeman, Ohio

 

I'm gonna try and pull just the head tomorrow, hoping it's just the head. If not hope that I can drop the pistons out the bottom and do a quick fix that way. Kills me to have it hurt over something stupid, best engine I've ever had in the car. It will remain our 2.3RPM as long as I can see in the future, that's for sure!

 

Just another speed bump. Soon the road for this project will smooth out and work out for you. Curious as to what happened to the motor though. Maybe the timing belt skipped. Hard to believe you just have no compression now. Im sure you checked the timing already though. Broken cam maybe? Im just guessing at this point.

 

It had beaten (including backing it up) AMS within 18 runs of being built to take them on, with a driver who was not a seasoned drag racer at that level - starting mid 9s and going quicker and quicker as he got used to it and as the power was wound up, a good percentage of those runs being 8 second passes. If you call getting steadily quicker and quicker throughout a single race season inconsistent - fair enough I guess. I suspect if they weren't shooting for a world record then it'd probably not have been a huge ask to keep it doing consistent ~8.6s and still be quicker than any other late model EVO racing at the time.

Considering due to the issues I mentioned (ie, not car related) it had quite a short stint of actively racing with that setup - the amount of videos of 8s runs you'll find on youtube of that one car will probably make up a healthy percentage of 8s EVO runs currently on the net full stop.

 

sorry to hear. thats a real drag for sure. seems you should pull head first since it has to come off regardless. real good chance bores are fine negating need to pull block.

 

We all realize the greatness of this Evo, but regardless of circumstances it didn't run 8's for a season... and who knows how much that would've cost them to do so. That's Dave's point...and he's pretty much right on this one.

Dave's not saying it wouldn't have been consistent, or that it was poorly built, or slow... he's just saying they didn't do it for a season...consistently.

 

Holy crap. We got the car apart, fantastic working with my buddy Dave who is also the guy here building these transmissions. We had it apart in maybe 40 minutes.

In 23 years I've never seen anything like what happened. All but ONE rocker arm is snapped off, everyone of them in precisely the same location. Not a single piece of anything went into the engine. The cams are perfect. Every single valve in the head is bent but none broke. The pistons are barely touched. We have been working so hard on our piston design for so long we have the reliefs very-very deep and precisely in line with where they need to be, so the valve hit flat on the reliefs and after wiping them didn't even leave a nick in a piston. The engine is oddly out of time though, all the marks are lined up but the engine was out of time. Weird **** going on. We just laid the cam gears back, so tomorrow we'll get the cover off and see what happened inside. Good news is the head is being worked on now, should just need new valves and the springs checked and there's a damn good chance we can run tomorrow night!

 

that is very cool to hear. I would think the crank being suddenly stopped would cause the cam gears and belt to keep turning. belt would just jump right over crank pully . two thunmbs up on your great piston designs and minimal damage. that would be awesome to see here make the track friday night after all.

 

David, is it possible that your RPM's exceeded your preset rev limit when the flex plate lost it's mechanical connection the the trans

Don

 

No, that didn't happen because the damage was after the car was shut down. The pass over, car was shifted to 4th to decel and that's when it happened.

 

Dave can snap a picture of the rocker arms?
