First Look @@ High Performance Injuns SpeedMaster Heads
Nice thread with lots of pics in the Street Section.
|
I have to say, castings do look nice. Now lets see what some CNC programs can do ?
|
Will be interesting to see users feedback about both quality, use and actual performance. Are these cast and machined locally?

Slice 'n Dice
5 Attachment(s)
Why destroy a brand new $700+ head? Because we want to offer our customers Quality and Affordable Reliability. I have more slicing to do and will be publishing the results in an upcoming magazine article.
So far these heads are exceeding expectations and that's exactly what we want to do. |
From the first group of pics, I don't see any garbage in the aluminum mix, no inclusions. I would suggest trying to drive out a guide to gauge the press on it. Doing the same with the seats will be more difficult. Looks like adequate material in the head bolt column. Only thing I see in the pics so far is any changes to the spring seat for larger, or more installed height should probably be done with diameter and valve length only. Looks like water is fairly close under the spring seats. Probably wouldn't risk cutting down more than .030" or so for clean-up. Keep up the good work.

Doesnt appear to have much water flow between center exhaust bowls, that area might get hot and see head gasket issues

If you care to do more testing on the quality of aluminium, send me a chunk of the head.. I will have our lab ( I work at an aluminium casting and exstrusion plant) run it through a bunch of tests...
I will send the results to you and you can do what you want with them.. |

SpeedMaster Heads Quality Update.
We received the band saw blade today so tomorrow I'll be at it again. Slicin' 'n Dicin' I've learned that with all SpeedMaster products, the R&D and engineering is all performed at their headquarters in Australia. The castings are made in China and the CNC machine work and assembly is all done right here in the USA. So these heads are truly international and many families are getting fed making these heads. |
My experience with Chinese "hard engine parts", is that machining performed in the US with US inspections and machine maintenance greatly improves the finished product. So that is good news. If I was Speedmaster, I wouldn't hide the steps you just found out, I would advertise the information. Another example of a company that can make this production method work is Molnar. Design and engineering in the US, Rough product from China, finish machining and inspection in the US. Need to get some of these heads on the track and street ASAP and really try and "prove them".

I believe Scat does their final machine work here too.

Thanks for the pictures and all the work for our hobby... It would be very valuable to have similar shots of e-heads, kre, wenzler, factory etc....

Hey, the casting quality looks better than High Ports. When Dave is done with them we will know a lot more.

SpeedMaster Heads Material Test
2 Attachment(s)
Thanks to Scott Roberts we have the tests back on the SpeedMaster Heads. I know not everyone can understand these results but what it comes down to is, as Scott states it, "Basically the aluminum is good quality A356".
Good material, good machine work, good price. Looks like a good head. $1799 a pair complete with free shipping. PayPal.me/RPMtv |

The tensile test put it right at the bottom scale of 6061 and top scale of A356..to be honest , I was surprised by the quality of the aluminium since it was Chinese.....

Once perestroika took effect, Russian tube manufacturers were forced to look for other clients, outside of their military. Turns out that Russian military tubes were very well built. Many of their tubes are interchangeable, or very close to European/American tubes. They have pretty much been the go-to guys for quality new production. Someone finally convinced the Chinese to try making and selling a high quality line of tubes. they hired the right people from England, locally and elsewhere and now there are superb Chinese tubes to be had. Psvane, Treasure, Genalex Golden Dragon are a few examples. They are not cheap, but they are high quality. Bottom line is that the Chinese CAN make high quality parts for our consumption. Trick is finding the correct sources. Speedmaster has evidently done just that. I wish them well! |

If you want to make an educated comment, purchase both heads and do real testing. Send it to someone who can actually test the hardness of the heads, the casting quality, machine work etc... It looks like an edelbrock head just copied without their name and the ports further developed. Just my distant observation without buying the head, this head will not out perform the KRE HP.

This head will fit in the budget build street performance class in my opinion... It looks like a good option for the masses... I would run it on a weekend cruiser. |

Everyone else knew what I meant. They have checked out to be good quality casting and the aluminum itself looks to also be of high quality. Now when Dave, a truly talented head porter does a few ports and gets the results in we will know a lot more. Is that too complicated a statement for you ? And I made the post to be nice to Randy. He is a true Pontiac die hard. I am friends with one of his pals from way back. He has wanted to start his own dedicated Pontiac business for a long time and finally done it. Its a good story and we all should be happy for him. There is a genuine market for Pontiac head packages. This price for 310cfm, this price for 340cfm and on up. Simple basic this price for this level of performance. Don't you have a house to paint or something ? BTW, the KRE comparison was simply about casting appearance. I do not think this head will out perform the High Port. And these are one more nail in the CV coffin. BTW, I will not respond to you any more on this thread. Too much respect for what Randy and Dave are trying to do. If you want to take it to the Clubhouse I am more than fine with that. Keep them out of it. slowbird and chiefblowhard too. These people are doing something difficult and so are the Warp 6 GTO guys. |

I wish him luck with these heads. I just wish he'd offer something new, like iron replacements. |
Even from the "Cheap Seats" :D I can tell this is going to be good.

You may have missed it or just didn't invest the time to read the previous posts, but High Performance Injuns has done the testing and provided the information and provided the flow numbers and sliced up a head for your viewing pleasure. Whatever history you and Dragncar have please take it outside of this thread. Thank you. |
How much are these bare?

Summit lists a single bare head with CNC chamber at $870 USD - https://www.summitracing.com/int/par...w/make/pontiac

Link says single head, CNC is US $870.50.
Confused? |
