    KC Turbos 6.4 turbo testing

    Hard to say, we have probably 6-8 months of testing still to go. We can start releasing some options sooner... but won't have the full lineup ready till next year. We have only just barely started on the LP turbos... still running the stock turbine wheel. Next we will jump up to a larger...

    KC Turbos 6.4 turbo testing

    We are running out of fuel… and have not even touched the HP turbo yet. We tried a couple different 71mm compressor wheels, then jumped up to a 75mm compressor wheel. Made some descent gains, but I think we are starting to get diminishing returns, I think we need more fuel? We are running new...

    KC Turbos 6.4 turbo testing

    Alright, now we are at the fun part. Taking something that already works great and seeing what we can do to improve upon it. . . Last setup we ran was simply a 73mm comp wheel, rest of the turbo was stock. It was a standard flank mill style compressor wheel that most people use. For this test...

    KC Turbos 6.4 turbo testing

    Vgt compounds vs t4 non-vgt single turbo with REAL data. S364.5/73/91 vs 73mm LP with stock HP. More turbo data! YES!!! My favorite. . We had the guys down from One Stop Truck Shop LLC today. They brought a 6.4 with s364.5, s2 cam, fass fuel system, and EZ Lynk tuning. We will be comparing it...

    KC Turbos 6.4 turbo testing

    Well it has been a little while since we have posted anything on our 6.4 testing here at KC Turbos. Better late than never? Right? . Chris Buhidar from Truck Source Diesel & Off-Road spent some time live tuning our truck on the EZ Lynk and it runs amazing! Coming from H&S the shifting and...

    KC Turbos 6.4 turbo testing

    You should ask Shane... he knows how it is going. We message a few times a week. But seriously, it has been slow. We ran into some wiring issues on the 6.4 and it was down for months. But finally back up and going. I will post a few updates.

    Kc300x

    Horrible plan IMO... we quit selling the D66 diy kits... they suck. That is a lot of the reason drop in turbos get such a bad name. Especially on a stick shift. This biggest downfall of these turbos is the turbine wheel. The drop in s300 style wheel helps... but a bigger s300 turbine wheel...

    KC Turbos 6.4 turbo testing

    Thanks for the support... I wish more people still got on the forums. I miss those days. But most have moved onto facebook which kinda sucks for posting actual data.

    KC Turbos 6.4 turbo testing

    hahaha... good one. Here is an even better one? Why don't you try Calling Elite diesel... the king of the turbos back in 2014 and try to order one. What is really ironic is that people said the same thing about the 7.3 being 25 years old... guess who totally changed the turbo game by doing a...

    KC Turbos 6.4 turbo testing

    No plans for a single... got the truck strictly for the compounds. Its crazy to think someone would take something that drives so great, spools so fast, and tows so well... and then rip it off to put on a laggy single.

    KC Turbos 6.4 turbo testing

    Well... she is dirty but finally up and running. Thanks Ian Gebbia for the hookup on the nice truck. 2008 f250 ccsb 4x4 black harley (without the flames) We bought her with a blown motor and completely went through it. KC Turbos is officially getting into the 6.4 turbo market... better late...

    205/30 T4 s369 vs s364.5

    Just FYI... the BASB and LASB turbos have tiny turbine wheels with larger a/r housings. Very similar to the 68mm wheel found in the s362sxe. The s364.5, 366, and 369 have a much larger turbine wheel... which seem to like the smaller a/r housings. If you add a big turbine wheel and larger a/r...

    s362 vs KC drop in

    It depends on the customer and a few other things. I have had customer get a non-vgt setup and HATE IT. Tried tune revisions, changed turbos sizes, etc... ended up going back to vgt. But I also have tons of customers that have gone non-vgt and love it, best thing they have ever done. Some big...

    160/100 vs 205/30 Injector Testing

    Only butt dyno numbers so far... but spools way faster and makes a little more power. We hope to be getting dyno numbers here in the very near future.
