Competition Boost From Twins

Big MAK: I'm not knocking the quality work that the folks from Canada are doing... . BUT, there are lots of other shops out there that can do a mighty fine job of cutting some grooves in your head/block.

Someone is going to have to prove some power with the HX-55, to date I know of no one that has done it. If your past a 40 in power and want to keep a single the only turbo I have seen that will deal with abuse is a B-1, after that it goes to Twins.

A ha Mr. Fulmer.



I know I won't be making some crazy power, for alas, it is but my tow truck, but this weekend starts the abuse on my '55 to the tune of 500RWHP, and my 12V with the '55 in twins starts it's journey May 10th.



HP will come from Track Calculators, and some dyno'ing, but, mainly track times.



As you may well know, I can screw up wet visions,, so I think the '55's will get proven soon, or not... I have faith. .

Deo,



I'm confident that you're going to like that setup.



Once you get the drains all figured out... you're on the home stretch.

Mak make sure if you do o-ring or fire ring you do both block and head. With studs it will last forever as long as the ring cuts are the right depth. 12mm good to 80lb and 14mm good to 130lbs and they are not kidding. I see up to 75 lbs with my setup and now that we are installing 14mm head studs, timing box, piers vp44 and mach 6's I bet I will see 90. As I found out in dyno testing more boost does not make more power. I had the most hp with 62lbs of boost on my old setup.
