    Brett Deutsch got a new personal best this past weekend at the UCC/ODSS race and ended up winning the ProMod class by surviving! Was definitely a rough weekend on everyone! We ran the entire eliminations without 2nd gear, we adapted and over came.

    #63 Manuel Vierra made a few hits at the event in Cali this past weekend for a new personal best of [email protected] which is great but not what he is looking for! This is still rocking 4.11gears unfortunately so once he gets the right gears in it she will fly!

    Twins with Twins, Anyone?

    Yes Tim, and it always works better at higher pressures and is part of the reason why the OE stuff overseas is approaching the 36-40K psi operating range now because it is a cleaner more controlled event with the higher pressure. Lowering the pressure causes the injection event to be slowed...

    Twins with Twins, Anyone?

    It is more a fuel quality(lubricity) vs pressure and heat generated for a sustained time period as the fuel can get pretty hot under load especially when you are cranking that kinda rpms and pressure. We have run their pumps from 29-34K PSI in competition use but Ken's situation is different...

    Fuel rail lines bursting

    Boschtech is a cheap chinese knock off fuel line that started popping up last year and they won't even hold up to factory line pressure. Been seeing this happen a lot lately as people buy more and more less expensive parts on line to save a buck but it always ends up costing then a lot more...

    Twins with Twins, Anyone?

    Pretty uncommon to see with Exergy's pumps but Ken doesn't always seem to have the best luck unfortunately! I just looked it up and I got my 12mmcp3 4-30-2013 and it has been through the ringer on god knows how many different engine combos and fuel system setups and is now in my wife's LMM that...

    Compression ratio question

    Great article on the subject and I've ran both ways with it. My last ProMod engine had 17.5:1 Oval race cast in it and I had zero issues with it but there is a lot to it making them happy. Street truck motors really should stay close to factory ratios to make them perform the best without a...

    Stainless diesel s485

    Awesome turbo to say the least, capable of 1400hp at the crank fuel only and well north of 1600hp with some juice. Pretty sure that it still holds the single S400 drag record also from Paul Cato@ Maverick Diesel.

    Twin engine duramax truck...

    Your not wrong but in this area it is hard to know all of them unfortunately. My father was a cop in this town when I was a young kid so when I got my license his buddies would follow me home and wait till we got to the house to turn the lights on just to shoot the shit with him, got to the...

    Twin engine duramax truck...

    Closest I came was being pulled from my vehicle at gun point by one very pissed off LEO! Apparently 113mph in a 45 zone is frowned on.....LMFAO!!!

    #74 Brandon Serpa changed turbos and went to the track this past weekend and set a new personal best of [email protected] with his stock motor LMM with big fuel and S400 turbo setup. Pretty awesome for sure especially for a stock motor truck still kicking it! (186) Brandon Serpa Stock engine...

    Going compounds on lml few questions

    Yes those are the current options available because of how the vane controlling in lml's works or lack there of. We are working on something bigger and better for them so stay tuned.

    Praying for you two Mike! Evan is definitely the best man for this job and to continue on a great legacy is going to be great!

    Going compounds on lml few questions

    That's a stock 4094va sized turbine so same size as our Stg2R comes with and we offer two sizes larger(71mm turbine in our 68/71stg3 and my 72mmvgt comes with a 72.5mm turbine, I am referring to the exducer of the turbine which is what matters when talking about over flow and power) than that...

    What's your favorite mod?

    Mine is always turbo related no matter the combo, I hate the stock turbos lol! Built trany is always a given! I love the torque more than the Hp personally so lugging through town at 1100rpms is my favorite thing as dumb as that sounds lol.

    Starting to really question the calibration with my DDP injectors - input wanted

    Means they just aren't efficient at the lower speeds and quantity which is fairly common with some companies stuff and it has to do with how they are modified. At the end of the day do they work correctly and did you get it to run how you wanted it too?
