#THUMPER CAM SERIES#

Owner installed a set of mutha thumpr comp cams #127020 with limiters, BBK twin 62mm tb, BBK longtubes and high flow cats, K&N CAI and exhaust then drove it without a tune to our shop (30miles all up hill). It's got a few issues as it stands right now, but most importantly no throttle response and it's setting P0340 and P0344 - cam circuit and cam circuit intermittent cods for bank 1. All is electrically sound except I haven't verified solenoid control. Talked to comp, they said it was installed wrong. Possible since we've had to go over and retighten everything done. Verified with oil cap removed the sprocket isn't wobbling wile idling - didn't rev to look for walk though. I did set the DTC to no error just to see if it would idle any better or get it's throttle response back - it didn't - not sure if I set it back to OE - will check later. Posting tune as it stand right now - base tune, nothing special - and posting factory OE. Owner never brought me the 'actual' cam card - wish I had it, but I don't - instead got the info off of comps website for the generic info.

Off of that I can see that the duration of this cam has the valve opening roughly 20 degrees sooner. Off of that I made the changes to the intake valve opening under the general fuel tab. It's an 05 GT Mustang, so not a whole whole lot of data. At least not in HP's scanner I'll break out the Verus today and see what I can actually see. It 'acts' like it's out of time, but comp did say that the locks could be misadjusted and cause the same problems.It sounds exactly like it is out of time. Even 1/2 of a link will throw P0340 and P0344 (if both sides are off). I have seen people put the tensioner guides on the wrong side, this will allow slack enough to jump before the tensioners pump up. I have also just seen people mistakenly miss the timing mark on the crank with both timing chains. Once the system throw P0340 and P0344 it typically disables all VCT operation, and all of your PID data for VCT will show up as 0. Well, no luck with the snap on verus today. With cams available in hydraulic flat tappet, mechanical/solid flat tappet and hydraulic roller configurations, COMP Cams® offers the perfect Thumpr™ cam for any street rod or traditional hot rod.Scanner was acting screwy so didn't even try to log my vct errors with HP. The cams come in three unique grinds known as Thumpr™ Mutha Thumpr™ and Big Mutha Thumpr™ each level fits a more aggressive application with higher compression ratios, converter stall speeds and other upgrades such as gears, aftermarket intakes and headers. The Thumpr™ Camshaft line has now been expanded to include classic street rod engines such as Buick Nailheads, Chrysler Hemis, Ford Y-Blocks and Flatheads, and many other popular options for classic GM applications. This maximizes any engine’s aggressive idling characteristics without negatively impacting streetability.

They are available for a wide range of engine applications, including the most popular power plants for street rods.įeaturing specially engineered profiles for each unique engine, Thumpr™ Camshafts provide the perfect combination of early intake valve opening and long exhaust duration, with a generous amount of overlap. Thumpr™ Cams are designed to provide outstanding sound matched with unbeatable performance.

Of course, COMP Cams has been on the cusp of this since the beginning, and has rightly introduced a new series of Thumpr Cams designed to not only provide strong, reliable and (more importantly) streetable characteristics, but also deliver that sharp, crisp “big cam” sound. This revelation has caused many to reconsider how much horsepower “they really need” – and while we jokingly howl “There’s never enough” we all know that’s not true. There was a time that increasing the output of your project car took some serious effort, yet now with an ever-expanding aftermarket, you can make as much power as you desire.
