Wildcardracing Posted February 15, 2008 Report Share Posted February 15, 2008 how much compression can i go without changing the stock crank?? i was going to get my crank trued and welded at fast..but im unsure how much compression i can run..im looking to keep 93 octane..i dont want to run racing because its getting very hard to find it I wouldn't go over 150psi on straight pump fuel, as far as the crank goes I would recommend trueing and welding it to anyone who begins bolt on mods...heard of shees with only pipes slipping a crank. It's just an insurance thing, always better to be on the safe side. Quote Link to comment Share on other sites More sharing options...

If any one can he that would be great. i live in regina sask and i put noss head on with 20 cc domes and was up around 150 psi. ok on pump gaz. looks like you need some pipes?? got a fairly new set of toomy t6 for 325. i bought a cheeta cub so no need for them anymore.

angler Posted February 22, 2008 Report Share Posted February 22, 2008 Got my noss head a couple days ago. Put that baby in today with 21cc domes and gained about 20-25 more psi. Its the best bang for your buck, defiantly. Looks good and adds hp. Also dave noss is the man! Does anyone have a purple...I mean "black" head? I have a black one but it looks purple. Oh well, other than that it's awesome! Nice fit, easy install, great compression, I definitely recommend them! Quote Link to comment Share on other sites More sharing options...

dlnoss Posted February 22, 2008 Report Share Posted February 22, 2008 Wow, that was black? How long ago did you get it? What do you wash it with? (Nothing should do that other than maybe an acid bath) I had to change anodizers a while back because the original one went out of business. PM me if you want to do something about it. It might be cool if you wanted one that color. -David Quote Link to comment Share on other sites More sharing options...
jamebo Posted February 22, 2008 Report Share Posted February 22, 2008 Got my Noss head around 2 months ago, and couldn't be happier with it. The low end power increase was great. I'm around sea level with 21cc domes and run premium pump gas. Didn't take long to install, either. David was very helpful with the questions I had about it.

Fireroad Express Posted February 22, 2008 Report Share Posted February 22, 2008 looks like the ano job wasn't sealed correctly or the head had a bad connection and did't draw the required amperage. probably the sealer though. Quote Link to comment Share on other sites More sharing options...
dlnoss Posted February 23, 2008 Report Share Posted February 23, 2008 As long as you are okay with it. It probably was a sealing problem. -David Quote Link to comment Share on other sites More sharing options...
angler Posted February 23, 2008 Report Share Posted February 23, 2008 So, I've been getting some PM's about the purple head. I guess it's a popular color. It's actually darker than the picture shows. It's a deep dark purple in the daytime. Anyway, I replied to the PM's, but no replies so I'm gonna put it up for sale. One year old, great condition. $150 plus shipping. Comes with nuts, new copper washers, new o-rings. Also, putting in for sale forum. thx! angler Quote Link to comment Share on other sites More sharing options...
rubberneck Posted February 23, 2008 Report Share Posted February 23, 2008 As long as you are okay with it. It probably was a sealing problem. -David So this in not normal right? I just ordered A black Fast head with my new motor, I dont want it to turn purple, id rather change to natural aluminum if that is the case.

dlnoss Posted February 23, 2008 Report Share Posted February 23, 2008 No, it isn't normal. They are supposed to seal it in a hot nickel acetate (sp) solution (I think it's nickel acetate). If they don't seal it properly, the color changes. -David Quote Link to comment Share on other sites More sharing options...
Fireroad Express Posted February 23, 2008 Report Share Posted February 23, 2008 a black anodized head should be and stay black. this is if the head was anodized with no connection problems and for the right duration at the correct amperage as well as sealed at the right temperature. if the anodize layer is to thin you don't get deep enough penitration with the dye and black can appear to look purple or brownish.

rubberneck Posted February 23, 2008 Report Share Posted February 23, 2008 SWEET, thats what i wanted to hear Quote Link to comment Share on other sites More sharing options...
Fireroad Express Posted February 23, 2008 Report Share Posted February 23, 2008 also if the anodizing on the head was not sealed correctly, the dye can wash out of the anodizing after time. Quote Link to comment Share on other sites More sharing options...
