is the zzx cam available as a hydraulic flat tappet cam or is it just a roller setup for l98's?

also, this cam listed below from lunati seems to be pretty similar to the zzx and is a flat tappet like i am looking for. this would give similar results correct?

ZZ-X Hyd Roller:

Adv duration 290/290, duration @.050 239/239, Lift .558/.558, on a 112LSA.

and......

Lunati 30143:

Adv duration 290/300, duration @.050 240/250, Lift .520/.540 on 112 separation

i havent priced the lunati grind but judging by the rest of their offerings it is probably under 200 bucks...an added plus. im also going to be spraying the motor so im thinking the lunati grind w/ long exh. duration and higher exh. lift would work well.

most likely a tpis miniram intake.

thanks for any input.

 

forgot to mention car will have 4:11 gears and a 3000 stall converter.

 

dude, you are just looking at total duration. If I were you I would look at where that duration occurs. There is a reason why cars with a zzx run hard. Also, look at all that lift you are giving up with the flat tappet. A retrofit will be $$$ but it will almost always make more power. You judge your own HP economics....

You have to give more engine specs before I would give you a cam rec.

 

stay away from tpis.....if you have to go with their intake just use the intake and check it over very well.

 

Why do you say stay away from TPIS? They were very helpful to me when I needed a cam. There camshafts are great quality.

I went with the zzx cam. Impressed to say the least.

 

long story short they overshoot their claims, highly over priced, and poor overall quality of products here and there. they have enough business to hide their bad business. just stating an opinion purely, but to put fact to fiction my miniram was porely casted and they did a terrible job of fixing it which i had to have gone over. their cam i purchased wasn't nearly what it claimed to be after tested and their programming skills are a hit and miss at best.

all of which wouldn't be a problem if their customer service stood behind their products but they don't. have a real problem or catch them in their lies and they will tell you to sue them.

so in short.........stay away from tpis, plenty of other products offering very close or similar items if not better for less amounts of money.

 

There may be companies that offer "good" parts for less, but do they perform like TPIS products? Doubtful. I do for a fact know that TPIS cams and intakes rock. I bought a 91 that trapped 118mph with all kinds of problems, that were unknown at the time. Mods in sig. You usually get what you pay for, same thing for LPE stuff.

 

believe what you must, but their quality is going down and their claims aren't exactly up to par.....with porely casted intakes, custom chips modeled after stock proms and cams that barely pull their weight you can say what you want but i wish i never gave them a dime. won't even get into their tech support and their believes on how to solve problems.

do their products work? yes.

do they work the way they are intended? no

if anyone wants to discuss them with me please feel free to pm or email me, but i don't want to take up any more of this thread with it. sorry jon_volk.

 

Well in all fairness to TPIS I think it is perfectly fine for a few others to say that their experiences were contrary to yours.

Myself, I suppose I don't count since I know the guys down there quite well. But I had them do the machine work on my 383 and assemble the short block for me. Granted, only 100 miles on it, but I am very pleased with their work - and pricing (for me anyways ).

I got my Miniram and ZZX used off the classified boards here as the prices on them were awesome and MUCH discounted from what new units from TPIS go for... But there is a reason I went with those products over others on the market... Anybody claming a ZZX "doesn't do what it claims it can" needs their head examined. First off, a cam is only one part of an engine and unless the entire package is built and tuned to work with it, it probably won't work well. Secondly, look around at the others running Minirams and ZZXs and you will fast come to the conclusion that they do indeed perform and perform well... I venture to say better than anything else on the market in the Miniram's case (again, IMO, but definitely supported by real world results).

As for PROMs, they simply cannot be done over long distances. Period. But will they (TPIS) work with you to get it right? Sure. Will it take lots of time and BS to get it done right? Yep. Do they charge a lot for their PROMs? Yep, see the previous question. Is it worth the money? Depends on your situation but unless you are local, I pretty much say no. What's the alternative(s)? Do it yourself or find a local tuner that can actually do it right for you since they can physically tune your car and not guess at it....

 

knowing them quite well doesn't do much for the word...

say what you will but i'm not the only one who feels the way i do.


TPIS is a waste of money.

 

What is "the word" ?

And vice versa .

Any and all products can and are viewed as a waste of money by some.

 

Back on topic... It is impossible to compare flat tappet and roller cams. The lobes are entirely different and the intensity of a roller cam is always higher than a comperable spec'd flat tappet.
