We expect a lot of dyno sheets & some good stories from you guys!! Too bad I have to work, My piped Raptor wouldn't stand a chance aginst you guys but it sounds like it's going to be a HE!! of a party!!!!!!

Wow this was the 400th post on this thread!!
I'm glad I've been reading it since it started, It would take all day to read from the start!!

 

Sounds like yall are going to hav sh!tloads of raptor-filled fun!

 

Has anyone seriously considered buying the Powell kit for the 770? It has a good cost and should make close to 70hp. I just want to know did anyone take it seriously?

 

FYI ---- If you are planning on going with the Powroll 770, a 760, a 727 or any other big bore/stroke motor, you WILL need more than a sleeve and piston.

With the 105mm or 105.5mm bore, you will need a new sleeve. When you install a new sleeve, you will need to completely disassemble and bore your cases to accept the new sleeve. Tear down, case bore and sleeve install (plus boring) could run $400-500.

If you plan on any of these large bore kits, figure on purchasing some aftermarket transmission gears to hold the power together. I have a 727 that let 2nd gear go under power. The result was complete destruction of every engine component except the cylinder head assy, clutch and generator. Even the cases and counter balancer were junk. $800

Don't forget a rod while you are at it. A Carillo is a great choice but they can be hard to find. $200

Now, the stock CV carbs should not be used on the really big motors. They simply can't perform up to par with the FCR carb set. But wait --- the FCR's don't just pop into place. You can either dice your frame or have a very custom intake manifold shift plate made. $850

Ah, the kit did not include an exhaust system or any cylinder head port work. pipe $400 Port $300 (without improving valves)

So, when you look at a piston, sleeve and crank pin mod as a "kit" --- be prepared to purchase the "other kit" (about $3000) necessary to keep things together.

 

Well said I wish that Powroll would explai some of these things to us!

 

I was just reading about how pissed scooby was about Knutz not doing his motorwork. Didn't I read about him bragging about his masters degree in engineering?(sp?) The way he said it,figured he could do it all himself....

 

I hated to see this thread dissapear to never never land. Does speedwerks have any big bore raptor kits.

 

OH now you went and did it 14min you feeling sparky latley aeee!!!

 

AZSAND- you have too many toys!!!!!!!
