I would like for you to tell me who did your port and flow work and how much it cost. Please.
I figure it will run anywhere from 200.00 - 400.00. does Craycraft or Robertson do this kind of work and if so how much. What kind of gains can I expect with this mod. on a 686 w/ hotcam stage 2? T.I.A.

 

Craycraft does it for 350 dollars. I think that includes doing the carb boots too. Turn around time is about 2 weeks. You will be happy with the results. Robertsons personal 727 was a fast quad, the others were not. What does that mean??? i do not know. All of craycrafts are runners. They pay attention to details over there. I do not know flow numbers and do not care, it hauls. I do know that RRC cc's everything before his brother does the work in AK and after he gets done. He has a book with the info in it on all the quads done. He might even have the numbers for a trinity, sparks and ct in his book. Shoot Raptorrc a pm. They also have some coatings availble for extra $. I have not been out run by another builder, and i get around thge country. ( i did lose to robertsons 727 with a bad clucth, i do not know if he counts a win against a crippled quad. I do not. lol)

 

I guess I better start saving up some Jack. I want to make a good showing for the next Midwest Sandfest. Thanks for the info.

 

Where is that, OOOOOOO you mean AR, right.LOL
Starting to sound like Capn Crunch aren't we.[img]i/expressions/face-icon-small-wink.gif[/img]
Are the coatings he uses a secret or can you tell us? That was serious, I'm just currious(sp?).

 

Capn Crunch is good stuff[img]i/expressions/face-icon-small-wink.gif[/img]

When in a crunch go with the Craycraft and sail the 660 CC's.

Ward- they are not secret. I do not know the name though. Some piston manufactures put coatings on there pistons. It is good stuff though. Keeps the heat where it needs to be. As everybody knows i tear my motor apart all the time. After 50 hours the coatings are still there. Pm rrc and maybe he will tell you the name. Of course it comes in huge bottles that cost$$$ and do 200 pistons and heads. A great product.I think that some ART and VERTEX pistons come with the stuff on them

 

I would assume it would be a Electro fuse coating.

I hear FTZ does a nice job on both 2 and 4 stroke. They are doing my head next week. A 4 stroke runs 350
and a Banshee runs 140.

 

nikasil coating. it is standard on many small plane engine parts.
