Huron Speed Twin Turbo Kit Review

[mmaattppllaayy]

I second that Jon is a class act. The best customer service out of any automotive company I have ever done business with. Awesome quality parts and prices. I would and probably will buy from Huron again.

You guys are making me blush.... haha

Seriously though I greatly appreciate the kind words and your support!

Got word of another car and member on here getting tuned yesterday with some great results!

so really, is that low AR number for more of a street/daily application? I just want to know the science behind it.

Twin precision 6266s standard intercooler. Optional manifolds and full mufflerless exhaust. Precision 46mm wastegates.

No, that is not low for these types of twin applications. All depends upon the set-up, engine size, use of the vehicle, etc. This kit uses larger T4 turbine housings, where a larger a/r is not needed to correct for higher backpressure. We can use a/r to hone in where the customer wants the turbos to light depending upon their use. I run billet 5858's on my car with the T4 .68 housings. Street car that just went 9.92's on the stock bottom end, turbos come on nearly instantly and have enough efficiency to still make excellent power up top! Most commonly we use .68 or .81 housings, rarely .96 for the big boys but this comes down to engine specs, goals, RPM range, use of vehicle, etc. A/R is simply the space available inside the housing. Smaller number = less space, therefore quicker to fill and have the exhaust hit the exhaust wheel and get business started. Larger A/R is more space = more space to fill with exhaust and a slightly delayed response to get going, but the end result is more volume to be able to hold, thus more efficiency in the higher RPM range where the engine feeds more exhaust. Good example would be a car driven on the street with a manual trans wants quick spool vs a similar car in auto with a cam that likes slightly higher RPM shift points. We may bump the a/r up to be a happy match with the camshaft.

Finally got the car on the track this last weekend. first time 1/4 mile with this car on this setup (only 9psi). Never mind the RT as this was more of a test and tune weekend. Super excited to turn her up next time and see what she will put out. This kit is super solid, couldn’t be happier with its performance. Stock engine with 6266 and npp exhaust. Thanks again for everything Jon!

When you say stock engine, do you literally mean stock? Stock cam/springs etc?

That is correct, only thing changed was injectors/rails, plugs/wires. No top/bottom end work.
