Between both of these spring which would be best for a cam up to .620 lift using Ti. retainers on a street driven car also will the GMPP hi-perform HydRoller lifter be enough to handle these springs.

 

It might be nice if you posted the spring specs.

Alot of LSX guys run patriot springs that are good to .660 lift. They are about $255 for everything including titanium retainers.

 

Includeing titanium retainers, are you sure? I would think the springs alone would be that much.

 

Springs, titanium retainers, locks, seats, and seals. They are the same springs that come on ETP heads, AFR heads, trickflow heads, ect.

 

Last set of Ti retainers I bought were over $200.

Plus I think prices went up over a year ago.

 

T retainers are a waste of money unless you are spinning big numbers. JMHO

 

Ok and that means?

 

I don't pretent to speak for him, but my guess is that is always sorta Pi$$ess people off (it does me) when something like the patriots comes out including T retainers, when most of us paid through the nose just for spring kits minus titanium retainers.

Titanium is one of the most prevalent metals on earth, and yet they used to sock it to us just for retainers made of the stuff-----and then along comes the patriots, of course I don't know the specs of the springs other than that they are good for 600+ lift.

 

Most LS1 people run them, and they handle the LSK lobes fine, so I think they could handle most of our cams fine. I'm thinking about replacing my 918's with them since all these 918 failure threads are starting to pop up since comp switched spring makers. I kind of lost all respect for comp when I found out that trickflow pushrods that are $85 are the same exact pushrods as the comp hi-techs that cost $145+.

 

It means, it sounds to good to be true. Do you get it NOW. How about a link so we can check out these great prices? Thanks.

 

They aren't a sponsor here so I won't post a link, but if you go to ls1 tech I'm sure you could find their website. They don't have any listed for LT1's but they make them and they are the same price. They also came out with platinum springs which have more spring pressure and are good to .660 lift vs .650 lift.

 

Yep: just one of the goodies you get with this site. At least when someone runs across something like this there will be cost benefits for those who are about to do some mods. Now I wonder if they sell the retainers separately and what sizes they have available. Just thinking aloud.

 

I wonder if they are any good at that price? Ti retainers are great, at least they were when a set was in the $100-120 range. They take weight off the top of the valve stack. Even though it's only a few grams, this can often allow an extra couple hundred rpm before valve float. In general, taking weight off the lifter side is unimportant, but taking weight off the valve side offers a lot of benefit.

Obviously, many setups do not need them. It's hard to offer any hard and fast rule, but if you need top notch springs, it is only logical to consider Ti retainers. Light valves can be quite expensive (hollow stem or Ti). Light springs are great - a spring also has to control its' own mass. Using stiffer springs has a self defeating element because they are usually heavier. This is one of the primary advantages of the bee-hive design. note that they are installed with the small diameter at the top, where the most motion is. Also, the small diameter only needs a small retainer. Ti springs (used on the LS7) are another option, but VERY costly.
