My baseline pull was 43rwhp and it's the little blue line on the dyno sheetLooks nice and shiny!
Did you have a baseline run before the port and polish to compare to? How much increase did you get?
I am running the Holz billet intake now, but it wasn't on when I did this dyno pull.Looks good Doug, Did you get the Holtz billet intake to go with it
That was at the base boost setting of 11psi.They took quite a bit of metal, looks really nice. And sweet gains at the wheels! How much boost?
MCX Turbo + Dynamic Racing Ported Head + Dynatek = 103rwhpSo what is the total HP after all your mods?
Matt has been working on pricing so he will chime in on that.Looks good! How much did they charge for head work like that?
That's really cool stuff! I'm sure what process they use but the result is the words fastest Stealth/3000gt, the most power Heads and Cam Viper and the most powerful stock block UTV on the planetVinamold would show you the flaws before the work and the finished product.
That's the Stock Deck Finish, since I planned on running big boost we did not take anything off the deck we did not want to raise the compression. I would like to do a 0.002" cut to give a better deck finish, but in this case we chose not to seeing how even with the shim the comp is still around 10 to 1 on the S. After my custom CP pistons I was running about 8.6 to 1 with this head.Any idea the compression ratio after milling off the chamber? I imagine it's Race Gas only now especially with a turbo. I'm no motor expert so correct me if I'm wrong, but I thought with forced induction it is better to stay away from high compression and small chambers with sharp edges to reduce hot spots and pre-detonation?
BTW - The work in the ports is nice. I'm suprised there was that much thickness in those areas. Beautiful work!
Going with a ported head will not keep you from running pump gas and will NOT increase compression unless you specifically requested it to be ported that way. All it does is make your engine breath a lot better and run more efficiently.That things gonna kick a$$! As much as I'd love the power, I'd only want to add turbo and what ever else to keep on pump gas. Also, adding that much power to these machines, will the drive train start falling apart? Didn't Mike already gernade his front end? I'm not just a dunner, so I would like to add as much power as I can and still be able to rock crawl reliably. Can't wait to see that thing rip through the dunes.
On the before pictures the burned rings makes it look like there's a "combustion chamber" when there really isn't. The only combustion chamber is actually just cut out around the valves which you can see really good after it was cleaned up.If thats the stock deck finish what heppend to the rest of the combustion chamber?
