BTR - Brian Tooley Racing Spring Kits: .660 Platinum or Extreme Hey Brian (or anyone who knows):
What's the difference (besides $10) between your two kits: SK001 and SK003?
I know the Max Lift setup is generally for roller rockers, but aside from some gold coating, is there any other difference in the Platinum and Extreme? I'm curious and thought others might be as well.
Also, what's your take on the longevity of the titanium retainers in a street use application? And what is the weight savings between your lightweight Tool steel retainers and your titaniums? I saw a post where your steel were within .5g of the competition's titanium, but I haven't seen anything on the weight of your titanium.
Thanks!

There is really nothing different, just the coating. He is selling the Extreme springs cheaper as he is no longer using them anymore after these sell. Just the Max Pressure and Platinum springs will be offered.
We use the Ti retainers on almost everything we do in house, but I sell a boat load of TS retainers with our cam kits.

The titanium retainers for the Platinum and Extreme springs p/n SR001 weigh 8.5 grams or 11 grams with locks, so they're about 5 grams lighter than the steel retainers. They're several grams lighter than most aftermarket titanium retainers.
I haven't seen any issues with titanium retainer durability in LS applications. I've seen the end of a flat wound spring damper cut into titanium retainers, but LS springs don't have a flat wound damper.
I assumed the steel retainers would be a lot stronger than the titanium retainers, but in the stress testing I had performed there really wasn't that much difference between them. The steel performed slightly better, but not a lot. I would also assume the steel retainers would last longer on the street, but having never seen a titanium retainer fail on a LS street car, means the steel retainer would last slightly longer than never a failure?
I hope this helps!

The Extreme springs and Platinum springs are very similar, but the Platinum springs hold their load better than the Extreme springs do. Once the inventory of Extreme springs are exhausted they will be dropped from my lineup. Although there are lots of people and shops who used the Extreme springs in the past and were happy with their performance and still buy them.

I'm assuming the lighter the valvetrain the quicker rpm pick up, or will it be neglible and unoticable?

The difference in retainer weight will not be seen in how quickly a engine revs. It will dictate the RPM at which the valve train stays stable to.
The lift looks like the Comp XE-R lobes, but the duration should be 224, so it’s hard to say. The Extreme RPM for LS1 lobes in the 225 duration range are in the .568”-.570” lift range.

great post brian! real data numbers, then real world 1st hand experiences. very refreshing. No marketing, "should" "better" "more average", in testing someone never did selling.
Your springs still going good on my heads, I'm hoping to check them before spring to compare to my notes of them new. I checked 2 sets of retainers on the same valve and hardware, and they all installed right at the same.
went back over everything thinking I something was setup wrong. haha. The other budget stuff I would find a few to mark, that were on the hi and low side. And place them were I wanted, same for springs. that isn't the case

BTW we don't use ANY other springs in our cam kits@Tick than Brian's springs. We've found the same things Studderin' has with the non existent variance in retainer installed height with Brian's retainers.
Every in-house install we do has his springs and every cam kit I sell includes his springs. That said, I still do a lot of cams for guys that run other companies springs as there are still others that have nice stuff for the LS.

Lighter cranks, rods, flywheels, etc can affect how quickly a engine revs and when those components are lighter more power can be measured at the crank.

Cincy Speed is putting a set of these on our girl now. I'm not sure which ones though. After doing a little reading here, I don't care which! Thanks for the great product Brian!
