You know Marlin, If you ditch the golf cart you can probably fit 4 or 5 of these bad boys.

Well, we indeed made it to the TnT at MGR on 4/6, but Amanda's special 12.90 engine is looking like an 'Epic Fail' [img]<<GRAEMLIN_URL>>/frown.gif[/img] The first time out the car would not go 10', it just sputtered and died 4x. I had oil &amp; fuel coming through a head bolt. Now, even after resealing, then a shorter bolt, then resealing it again, I can hear the compression coming through the bolt by turning it over slowly by hand! The engine has but 42 passes on it, still has the cross hatch in the bore! In theory, it should have at least ran down the track (poorly), so we ordered up the special HP 12.90 clutch ramps - no different. So I'm shipping it back to HP for a full evaluation. Beyond bummed. [img]<<GRAEMLIN_URL>>/mad.gif[/img]

We installed the backup engine for now, and will fire it once I get the oil baffle system reconfigured. I guess I should be happy that we even got this far with the second car so early in the year - which is when you want to find this bad stuff out. Still a bummer.

Ben's car ran well considering we changed his engine too, ran 8.82 right off the trailer and an 8.88 after a clutch adjustment - very close to the magic 8.90 number. He was thrilled with his car, not so much with having to pilot Amanda's that day as he remembers all to well our issues with his 12.90 setup.



Ben in 'The Slow Car', at least it has the 'Boy Body' on it for the TnT!



Block face sure looks clean, note slight 'scratch' on the top - can't imagine that is the culprit though.



Very clean bore:



Overall, a bummer of a day, but still not a bad place to be - at least the golf cart went faster (we bypassed the governor mechanism [img]<<GRAEMLIN_URL>>/grin.gif[/img] )

Sorry to hear of the troubles, M!

Early season blues. Don't worry, you will figure it out and win rounds.

[wannarun70]

Sorry to hear that. Hopefully it will only get better. Good Luck. [img]<<GRAEMLIN_URL>>/[/img]

The engine was delivered to Huddleston yesterday morning. We are awaiting the results of the evaluation, not sure when we will get to run it with that engine. Bummer, eh? [img]<<GRAEMLIN_URL>>/mad.gif[/img]

Evaluation: porosity within the cylinder head casting, [img]<<GRAEMLIN_URL>>/mad.gif[/img]



The small dark spec's are deemed to be casting imperfections that have channeled their way to the center / forward bolt hole.

The best remedy is still in R&amp;D, which is a billet head. So, while the engine is at the builder we will upgrade it to 'version 2' with a bore/piston/rod change. While I might need to add a little more weight to slow it down, the bigger bore pulls a better carb signal and allows for better tuning and consistency. Till then, we will start dialing in the backup engine - hopefully tonight.

So, with backup engine still installed we ventured out once more! Last Friday night's TnT went relatively well with Ben running Amanda's car down the track for it's inaugural run, clicking off a 12.70! I was surprised, and pleased that it was that close to 12.90. Next up was our 'hired gun', 9 year old Brealyn who was able to make 2 runs Friday night. He kept in it the whole way, clicking off a 12.66 and a 12.64. Not bad!

Ben jumped right into his car, making 4 additional runs that were all within 4 hundreths of a second - he was happy! [img]<<GRAEMLIN_URL>>/grin.gif[/img] I was exhausted, [img]<<GRAEMLIN_URL>>/eek.gif[/img] Running back and forth between the lanes at the starting line is hectic, the starter thought I had lost my marbles! [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

Staging lanes:





Sunday was a points day, so we were back for some competition. We added 25 pounds to Amanda's car, it barely slowed down [img]<<GRAEMLIN_URL>>/frown.gif[/img] So, we added another 25 pounds, and the clutch didn't like the extra 50 #'s to lug out of the hole and stumbled a bit. Brea clicked off a 12.98 on a 12.90 dial, but could not overcome an experienced 7.90 car.

Ben won first round on the tree, dumping a 7.90 car at the stripe. He was pumped, only to give up the stripe on the next round when he absolutely treed the other kid and then scrubbed off too much at the line - tough way to lose a round. Took some time, but he got over it and is looking forward to the next time out.

The pits are getting busy!



Hope to get Amanda's primary engine back next week, then it's back to thrashing!
