logan is dreamy....I mean the intake......
Very coool best of luck with it
looks good, can't wait to see it on the salt. Logan knows what he's doing, Bobby is in good hands. Look forward to sharing some brews and bullshit in Bonneville!
I'm diggin it. Two reverse induction nailheads can be seen on the
"Drag cars in motion.....picture thread. Both blown,one in a digger
the other in a boat on page 260 http://www.jalopyjournal.com/forum/showthread.php?t=228509&highlight=blown+nailhead&page=260
Thats the boat that I have heard about, Its local to this area, and that looks like Irvine Lake to me. What an amazing engine!!
Hey Bobby and Crow Crew-
Good luck! It sounds interesting, video sounds never do an engine justice...
Can't wait to see it run at Bonneville!
bobby G and Lucky and the rest of them are real COOl car guys helpful and nice always got a smile and they will answer my dumb questions..... thanks guys.....
34 is the deal....
I'll chime in with HotRodVon, wish you guys all the luck and hope you knock em dead. Quick & Easy Racing team.--TV
Thanks everybody for the positive words.... Experimenting is always a risk, so I'm not making any bold prediction.. but I am hoping for the best. Knock on wood and all that.
-Falls over laughing-
Cool!...good luck at B-ville!
I'm doing some shake down runs this week, so I'll let you know how shes runnin.
So Bobby, Why no more boost? I guess the motor was just to picky or could not take boost and be reliable? Inquiring minds must know.. lol.
FNG respects (and more go fast to ya!)
1'st pic , no "pyrometers"
2'nd pic "K" type thermocouples (weld in I guess)
3'rd pic 4 gas probe for tuning??
The sound....no mistaking that torque, keep the band flat
and peak to peak 1 min, kick butt!!
BTTT im curious how this thing did, i just found the thread and it is pretty awsome. Did you ever get to do any test runs?
They set a new record at Bonneville... I (and quite a few others) helped finish off a bottle of Old Crow whiskey to celebrate!
I was able to see it run..its awsome....one of my hi lites of the trip
Hey Bobby, Cool to see you guys at the Bend in the Road, and your new record. I would like to take a moment to tell the gentleman in your pit,(Long hair no Tats) good luck. He mentioned this weekend was his last hoorah before inlisting in the US AIR FORCE. What a great way to spend time before heading off to Bootcamp. He will make some big changes for the better. I, and the rest of the Country, are very proud of him. We talked for quite a while. and he explained your engine to me. Very nice guy. Please tell him Thank-You for defending our Country, and giving us the Freedom to be at Bonneville. We will owe him someday. Brian
That Long hair Hippy Bastard would be Tyrell Pennington, Lovinly Known as "Kid Rock"
I have had the Pleasure of knowing this Young Man for a couple years now, I think hes MAYBE 21 now, When i met him he was driving the COOLEST Pre~War '30 Roadster & has since stripped it down & painted it & built a HOT flathead for it.
He has been a Helper For Logan Davis who does All the Mechanical work on the Old Crow for the speed shop.
Very Impressive Young man & a Real Go Getter, Even though hes a Smart Ass & we go round & round when we see each other ... GREAT KID !
Now he is off to Defend our Star's & Stripe's.. I/WE will be indebted for this Young Man the rest of our lives.
If your seeing this Tyrell, You better come home safe ya Fuckin Hippie.. You still owe me $100.00 for that convex S/W Gauge !!!
Thanks for the note DESOTO. We all wish him well. Way to be, "KID ROCK"! B
So,...what's the latest Bobby?
I'm interested in the possible heat issues that are rumored?
"If you notice for the last 50 or 60 years it has been the norm to have exhaust ports smaller than the intakes"
That wasn't ignorance, or bad planning. It was sound engineering, and it's still valid today, except the engine design for which it was intended is no longer built: no overlap.
If there is no reversion-induced exhaust gas re-breathing during overlap, the most efficient exhaust is the biggest valve and port you can use. This allows the working cycle to be extended by opening the exhaust valve late, which increases power. Pumping loss is still acceptable since blow-down is very rapid.
Once engines started using even mild overlap, reversion was cured in the crudest possible way: shrinking the exhaust port to raise gas speed. This, in turn requires the exhaust duration (and lift) to be extended, which causes more reversion, blah.
The new Crow engine is fantastic. Talked with Logan about the intake and fenders he built at your Pit at Speedweek. Great looking stuff. The Video is a first rate. You can start your own cackle fest. Great work, Thanks for posting.
i just love new old speed ideas!!! great job, from head scratching to fruition!!
I just plain 'ole wet myself! See ya' all on the Salt Gpa Crow.
Killer set up !!!
Being in Indianapolis i have breakfast with some of the old school Indy 500 guys . Some of these old guys have spent many hours on the dyno etc.
Every now and then i get them fired up talking about the reverse flow engines etc ( where the intake and exhaust is swapped.)
Makes for some interesting discussion in regards to getting in more fuel and the getting it out again.
Many claim that when you increase the ports to get it in , you then cant get it out and vice versa.....theres a few of these engines running the Newport Hill climb each year with the t engines as well....
Any chance you will get some dyno time on the engine? Looking forward to seeing you at the Salt!!
This thread is 2 years old.....just to let everyone know.
