Thread: Polaris Matrix
09-01-2007, 09:17 AM #1
There were approx 6 Original Matrix boats built in the Polaris R&D facility in Spirit Lake Iowa. They were built by Dave Delaughter, Mark Baxter, and the R&D crew. They assembled two boats in the OEM Production colors of Red top & Black bottom.. The remaining four were built with Red tops & White bottoms..
They were tested & tuned on 92 Octane pump gas with no problems, and went through plenty of "endurance testing". The top speed varied between boats, but was in the 67-70 Mph range at approx 7600 Rpm.
Something obviously happened between Pre-production and the scheduled production boats, as virtually everybody has determined that 99% of the triple pipe Matrix boats will NOT survive on 92 Octane fuel..
I personally feel that the weight of the hull attributes to the detonation issues, as you can build the same combination for a SLTX /Virage hull and run lower Octane levels. The pipes can also be part of the issue, as there might have been a small change in the "convergance cone" dimensions and/or a stinger diameter change.. Even a waterbox / exhaust flow can make a serious change in the fuel requirements.
WHO CARES, as long as people realize this is a special boat, and there are still very few produced..
Thanks for listening..

5 in Florida ..1 of them has different triple pipes than the others(i think pre-production??? not sure)..and also one of them looks like it has a totally different pump.

I heard through the grapevine that you did some R&D work on the head for the matrix. Is it true?

All the pre-production Matrix boats came with a cylinder head I designed and sold to Polaris. It's a "one piece" Design with a girdle kit.
Later Factory pipe produced their own cylinder head, and it was a "one piece" head with non-removable domes and no girdle kit. There are other head covers available that have made their way onto Matrix boats, but most used one of the two listed above.
I have attched some photos of the Watcon head.
Oops.. Most of the photos are for the "Twin" version, but you get the general idea. The Bottom left is the head cover / Girdle kit for the Octane.

Look at Randy's (Watcon) posts very carefully and you'll figure out exactly what the Matrix problem is due to. I can't say as I have been told not to state it on any forum...but you can piece it together from the above posts...but it's not easy to piece it together...takes some deductive reasoning.
