Cams & cam regrind discussion as a performance adder

I have been following this thread but I might have missed this info, has Bill done any R&R to show that these do what he says they will? I don't mean anything by this question please understand, just wonder if there is numbers to back them up is all..
 
I don't know if any of these other people on here have been for a ride in Joe's pickup, but I have and it does pull real hard. The new computer program with the HP3 cam will set you back in the seat and hold you there. Joe's pickup still has the stock air filter too, no CAI! The throttle response it right there, at most any speed you give it a little throttle and away you go, except faster than before. The ones who have bought the cams will be able to talk about it soon enough.

I was under the impression on a regrind they ground the bottom of the lobe to achieve more lift etc.

Two ways to skin this cat.... one leaves the lifter lower in the hole due to grinding with extra duration and reduced extra lift.....the other the lobes are built up first, then reground, giving what ever you desire and lifter is not starting to move valve already being extended....one of the nice things about hydraulic lifters are that they will compensate some what for "length issues".

IIRC, the Delta re-grinds that guys were doing were costing about $300.00.... might be wrong there though, happens often. There is a lot of info, on all the 6.2/6.5L sites for those whom desire to search.
 
I will be watching and reading to see. I was just curious about the towing grind, it would be nice to see roller results before & after. And for 5-6 bills, it would need to be a large improvement IMO for me, as I run a DB2 setup, no computer to tweak.. but I do have a large turbo to go with the build when the time comes, still waiting on parts to come in.

I do like the idea that someone is working toward better things for our rides tho....
 
I like it when a mod improves performance without added fuel. Like exh. does.

Any chance you know what the prices are ??

Does he regrind my cam or ??

I'd call and let him know you were sending your cam with a money order for one of three available. Save you and him the $100 core charge/refund dance.

Here are the three cam types, information and updated designations for them:

HP#3 camshaft and spring kit. $595 exchange $100 core deposit
Performance applications.
Requires P-3 computer tune and Turbo-Master boost controller in order to achieve full benefit. PH#3 / P-3 combination typically set to 4800 engine rpm limit with 4600 rpm full throttle automatic upshifts. P-3 tune features automatic transmission settings and calibrations designed to maximize vehicle performance. This combo delivers maximum power and torque along with virtually smoke-free operation, excellent fuel economy and fantastic overall drivability----it has no bad habits and there are no drawbacks to it operation.
Details of engine and transmission tune discussed with customer prior to programming.
Heath HO fuel injectors, Super-Flow exhaust system, Hi-Flow crossover pipe, Cold Air Intake system, Heavy-Duty fuel lift pump are all required for maximum power gains.


HT#4 camshaft and spring kit. $595exchange $100 core deposit
Towing applications.
Requires T-4 computer tune and Turbo-Master boost controller in order to achieve full benefit
Combination enhances towing / pulling power in the 2000-3000 rpm range. It delivers excellent fuel economy and a virtually smoke free operation. T-4 tune features automatic transmission settings designed specifically for the towing or hauling application. Combination delivers excellent overall drivability with crisp throttle response and excellent mid range power and torque.
Details of engine and transmission tune discussed with customer prior to programming.
Standard output fuel injectors, Super-Flow exhaust system, Hi-Flow crossover pipe, Cold Air Intake system, Heavy-Duty fuel lift pump are recommended for maximum pulling power gains.


NA-66 camshaft and spring kit. $595 exchange $100 core deposit
Naturally aspirated 6.2 and 6.5 applications. Enhances torque and power across the full operational range of the naturally aspirated 6.2-6.5. Additional gains are enjoyed with improvements in exhaust and intake airflow.
 
GOT to love and respect that marketing. I am going to have to take his marketing course. :agreed:

Reason it's gotten lackluster enthusiasm for cam rework, many have tried and bottom line even with the assistance of some big names in the cam bidness, a lot of work with marginal gain over the cam GM supplier the 6.5 with, it was a topic under consideration for the Heath LSR but after much R&D they are still running a stock cam, if any ride were to benefit from a regrind, that would be the one.

Now a cam with opened up precups and some tweaks possibly another ball of wax, rather than dilute information thread with theory talk let's take that discussion to the performance area where if it is wished to be expanded the discussion can be picked up there.

If ya'll want to discuss the cam talk carried from this thread Buddy was referencing http://www.thetruckstop.us/forum/showthread.php?27096-IDI-tecchie-info-courtesy-of-Great-White have at it;

I didn't want it to detract from the information purpose of a reference thread, it's a good topic for discussion just better suited here than in a reference post.

Bill's ride isn't only game in town albeit it is the worlds fastest 6.5 and running std precups, a wicked tune, twins, but has a stock cam, a hybrid cam tried still not getting the job done last time I talked to Bill.

Another Diesel gearhead Dennis Garmon of Garmon performance I met at a dyno day had tried some special cam work on his 12V Cummins 500rwhp #2 fuel only ride, said special cams for him weren't good power adders either and suspected for my 6.5 it would not do much, but said try it; only way to know for sure is to try.

I had started a lengthy response but figured what the heck, go for it do your cam thing if it works we'll all celebrate, FWIW more than just a grind has been attempted including springs, lifters, timing etc. required for a complete review of making a different/better cam work. Fuel is limited for a reason for tunes available to the mass public you ought to be able to figure out why.

Good night Buddy

Does no one else find this some what ironic ? We read here that these have been around for a long time, yet only last year when the original poster brought this up, he was told in no uncertain terms it was a waste..... I included the link to the reference thread again for those of you with inquiring minds....:rof:

So are there any dyno facts behind this cam or is it just butt dyno? 60hp is a big number or is that with all of the extras needed to "realize the full potential"?

I know Tim (Turbine Doc) would not lie about what he was told by someone else. So maybe he was not given all of the information that was available.
 
Without the dyno set up at the shop, they used quarter mile times, vehicle weight, RPMs etc. to get a math number. Not sure how that all works as I've never tried to figure it all out.
 
60ish HP is still nothing to sneeze at. Not that HP numbers are a "all in all" item. No ones mentioned the tourque numbers that are sure to explode. Throttle response? Besides, its $10 per HP. Quite the investment.
 
I think I would need to see real dyno # as for HP & tork, I don't know about the 1/4/mile runs, my build is moving towards the towing /tork side of things in the lower RPM range. Now if there were real dyno facts to back up the claims I would consider it, but from past threads on their not being much gain, the price - gain is unknown for me. If & when they show dyno facts that will be different for me, but until then??

And I don't have a computer to tune, my DB2 marine would need to be tweaked I would guess. and that would be even more $$.
 
sctrailrider I'll be doing a dyno run with my 6.5 this summer with the towing cam and a DB2 pump. If nobody has bought my old gm4 turbo by that time i'll do a run with that and another run with the ATT.
