Competition Porting

[COMP461]

I along with Ray feel that the MLM gasket will hold with ARP studs, Project X Diesel doesn’t have a problem with head gaskets , and this is at 862 hp and 1655 tq uncorrected , I really believe that at some of the Dyno events I have seen with the big correction factors, Project X would easily make 1000 hp. I let Wes Snow (Crawler) race the truck, he has run a lot more nitrous then I dynoed with , and the performance gains were 3 tenths in the 1/8 mile This would equate to about 4 tenths in the quarter. Making Project X a true low 11 second truck. I believe the problem with any diesel and head gaskets is tune, nothing more , stack this on top of that , add in this and you get what for timing and fuel.

NO Project was a max ported head , flowing almost double a stock head, and we lost a 200,000 mile water pump during HOT ROD Magazines Drag Week, (thanks Illinois Dyno Center) for rushing us parts and extras to the track. The 24 valve head is very well suited to porting , the area that can crack or very thick, if you are going to use a head porter make sure their have that head m and casting version cut up. I do know that Buddha and ray both have these heads , Buddha dose not , repeat dose not do work for anyone but dedicated racers , he is only for the serious person, a head from him is the extreme starting out at $8500 and up. Ray charges similar prices for a comparable head. RayMac has a dedicated diesel head porters that will port to you budget level. Speed cost, how fast you want to go. In any form the 24 valve head will live on a street machine in a fully ported version. A note on John Russin he is the absolute best on P-pumps and injectors along with Cylinder heads , with that said if you are lucky enough to have his number , be serious , he will not tolerate a “street Squirrel” he is pricey and worth every Penney.

I have a invoice from Nickens brothers racing engines , this invoice is from the early 90s and is for $ 35,000 for a 283CID single 750 carb small block racing engine, for a competition eliminator class. A lot of people asked why so much , because the parts , and work were no where close to that. Nickens bros. answered that question on this invoice on the first line “ for what we know that makes you faster then the car in the other lane $10,000” this is in play when you go to the best . John Russin and RayMac are in this category. So one more time speed cost !!!!!!!!!

I'm sorry... ... ... but how can you possibly put those two names in the same sentence? John Russin has done waaaaaaaaaay much more R&D with DIESEL's than Ray-Mac Machine... .

Not taking anything away from Ray-Mac's abilities with engines, but John Russin has been there for years- and you know this to be factual in my statement... ...

And one is better off getting the price from the man hisself -not thru internet chatter.....

AIR FLOW IS AIR FLOW !!!!! A cylinder head is a cylinder head; Ray and his air flow specialist are some of the very best, coming from NASCAR and ProStock back grounds. They work on the best flow benches, developing some of the very best programs out there. I believe that until Ray decided to dedicate fixed resources, and hire additional air flow specialist, John was the only one in the diesel world doing anything close to real air flow technology, the norm was to grind as much metal as possible out in the easy to reach areas, and call it porting.



I have look at some of so-called stage III heads from others in Rays shop and they look great, to the untrained eye, but they flow terrible numbers. This isn’t a Ray vs. John thread, both are the top of the diesel world, and length of diesel experience in not important, air flow is air flow. There is nothing magic about diesels; it’s just a reciprocation 4 stroke Otto cycle internal combustion engine. Its just a power plant intended to power a race car or sled. I will not get caught up in this normal for some people, my guys better then your guy deal, which hides these treads in the banter section and hides this important information.



Ray is pressing forward on a 12 valve program, the numbers are looking good, and with a ZZ manifold that is made from Stainless steel per advice from John. Remember there is only one of John, and the average guy can not afford him.

Granted they may have backgrounds in Nascar and some Pro Stock, but last time I checked they didn't allow turbo's nor diesel's in either of these types of engines.....

Ray-Mac was 'pushed' into diesel's- and we both know who did the pushing- does this automatically place him at the top of the diesel world, where John and other's have been firmly rooted for quite some time??

Again I am not taking any of Ray Mac's experiences or knowledge away- he knows what he does, but the diesel thing was some project on the side of his main bread and butter builds.....


Where as John has any diesel heads ready for battle on his shelf waiting to go. And with his years of research and development that he does on diesel's, you are comforted in knowing you are getting among the best in diesel power building available... .

 

[Forrest Nearing]

agreed, a cylinder head is a cylinder head... granted, we are severely hampered by factory castings, but that's the way it was back in the old days and still is with various classes.



I can't afford Jack Roush, or John Russin... and honestly, if I could, I'd still use Ray

I'm not making this thread into anything vs. anything... ... . but you cleared it up with your noting of 'the best' calling JOHN for advise... .

clearly that says it all... .....

Back to the subject- yes -while you have your cylinder head off, I would invest in a streetable port and bowl clean up port and polish. You can gain significant airflow-while keeping the factory intake plenum attached, by directing the majority of the work in the bowls and slightly cleaning the ports, without issues..... and easier breathing along with a good EGT reduction as benifits.....

Thanks for all the replies, I'm gonna go ahead and get it ported... just no sence in taking it off twice. Should I ask for flow #'s? Has anybody used Steve at DSS in San Diego for porting? Can you guys suggest anybody around Southern California for porting?

 

[RacinDuallie]

Without a doubt if you can get before and after flow bench numbers- GET THEM... . Just make sure they are flowed in the area of your cam lift range- no sense of having big flow numbers at . 500" lift when your cam doesn't lift that high.....

Never heard of Steve at DSS -personally... ...

the best way to get power on the west coast is to ship your head back to the east

 

[COMP461]

you can send it to RayMac 817 568 8822

 

[Timebomb]

Can anyone give comparable flow data from a flow bench. Like what a stage 2 PDR head would flow on a bench or Ray Mac or others. Lift and Flow from a superflow would be nice.

 

[RacinDuallie]

I do have a flow sheet from a PDR Stage 2- 24 Valve Head somewhere here..... lemme see if I can dig it out.

I will also have some flow sheets from a cylinder head I've been playin with. This cylinder head in comparision to the PDR Stage 2 is completely different..... But between the 2, they are completely different animals... . I'm expecting to see a substancial increase in flow numbers..... This is a 24 Valve cylinder head. I also have a 12 Valve head waiting in the shop... ...

This head will be a track only head... ... Oo.

 

[Timebomb]

Cool, I was going to send my head to Maxflow Motorsports in Newmarket Va. to be flowed. He works with superstock tractor heads a good bit. But I didnt have the time.
