Hey guys, been a little while again, but I though I'd post on the progress of putting the old 511 back together.

I took the crankshaft to Strasburg machine (the top fuel guys), and they wet-magged the crank and checked it for straightness. It passed. That tells you how tough those billet FE cranks are. Shagged a piston at 7000 rpm and even though it went horribly out of balance it didn't hurt it. Quite amazing to me. It had some slight marks on some of the journals, so I had them turn it down 10/10. I went to Salt Lake City yesterday and picked it up. Looks perfect.

While I was in Utah, I took the block and damaged head to the the guy that does welding for the Strasburgs on their Top Fuel stuff. He looked at it and said it doesn't look like a big deal. He showed me a TFX fuel block that was in for repair and believe me, mine wasn't even in the same league as the damage that thing had. He is going to grind the sleeves out instead of pulling them, since they were damaged pretty bad. If all is well underneath then I'll order a couple of sleeves for cylinders 7 & 8.

That brings me to my next problem. How to rebuild it. I went with nitrous last time to overcome the altitude issue we have here. Although it worked well, it isn't convenient. This time I am thinking of supercharging it. If I stick a little 8-71 on it, and build it mild, I should have an setup I can cruise around town in, and then change the pulley and add race gas, if necessary, to go fast. Since I only want around 750-800 HP I really don't think it will be that hard to do. It shouldn't require very much cam or compression, and a couple of 750's should feed it just fine.

What do you guys think?

Glad to hear it's going to be up and breathing fire again! Pretty amazing that everything is fixable. Sounds like you have the very best doing the repairs. I'm not much use for knowledge on something like that... just an avid fan.

The video of it dropping a valve still haunts my dreams...

I would think a 8-71 would solve your altitude HP problems.

Have you thought about turbo? They are the hot thing right now, and I personally wanna use a turbo for my next motor project.

Any blow through application turbo/supercharger would be alot less sensitive to altitude changes then a draw through "8-71".

 

I agree that the turbo would be the best way to go, no question about it. With the engine management systems and boost controllers and so forth you can't beat it. That being said, I am somewhat old school. The roots blower, although inefficient, is simple, and carries a certain appeal for old farts like me.

Cant wait to see that thing back on the road!

 

Hey Brian, great news...

BLOWER!

 

An 8-71 should give you 800hp easy, with a mild set up. Just watch the compression with the stroker crank will need a set of custom pistons which should be no big deal after buying an alumnium block.

 

Brian, Just wondering & thinking out loud, Why in the HELL would anyone want to cruse a 800hp engine that one might have $40,000.00 of time, money & effort in on the street?

I just can't imagine.

No **** offered either, so no contest needed to be started.

No offense taken. I'm not sure what part doesn't sit well, is it the 800 or the driving it on the street? If it's the money, that's the main reason I can't just let it sit in the corner. It took me years to save up to buy that engine, and many, many hours of planning and modifying. I want to enjoy it again so all of that isn't wasted.

If I had an 800hp FE, I dont care if it's the original Carrol Shelby AC cobra supersnake that sold for $5mil, I don't think I would drive anything else! I agree with you, enjoy it!

 

+3!!!!!!!!!! 800hp on the street is killer! My friend has a 822RWHP C6 Vette and just yesterday we went for a spin and I got reminded what the back of my throat feels like! 0-60 3.3 sec yesterday according to his in-car-meter. !!!

 

I guess it's because you can.

I agree, what's the point of having it if you don't drive it, nobody is gonna ooh and aww over it sittin in the garage. Besides, the only reason to have a trailer queen is if your going for the Ridler or the AMBR awards.

 

With a good set of drag slicks, he should be under 2.0 second 60 ft. times. Scouder was under 2.0 and we did 1.460 for 60 ft. and both of us have around 800 hp.

 

It was 45 degrees, 285/18 mickey et street radials, shifting slow. Doesn't even have his twin disk clutch in yet, and it'll slip with the clutch now if he gets on it too hard... 6000ft High altitude, as well. Nonetheless, 822RWHP, M6, 4:10, etc... it's a 9 sec full street car. By far the scaryiest car I've ever been in!
