We have tested them on the dyno on a .708" lift cam turning it 7500 RPM and they had no problem!

I wouldnt admit a problem if I were TSP either.
The only spring failure I witnessed myself was on TSP Jasons' personal black 2010 Camaro that you guys did the install on. The #4 intake valve spring broke causing the intake valve to break off into the engine. This happened 1800 miles after the new owner purchased the car from Jason.

So your PRC springs are good for .708 lift and 7500 rpm?

I'm not comfortable with their .650 springs on the LS3, I don't feel they can control the intake valve very well with the low pressure. Friend ran into issues with his setup, and after measuring some fairly fresh springs, I can see why. I do, however, like their EHT .675 springs, which have significantly more pressure, and have no issues turning 7k in my personal car with them with the TSP cam.

A lot of folks dont realize that valve springs are a wear item. 12000 miles/1 year and they're pretty much toast with a large/aggressive cam. Had another friend I know pick up 30whp with fresh springs at my suggestion after 20,000 miles on his and low dyno numbers/early tq and hp peak. Go figure

That is true my car did have a failure from a old version on the 675. The previous run of 675 springs were the ones that occasionally failed. Relative to the number of spring kit sold it was a very small number.

The newest 675 spring has only had 1 failure in my last run of 20,000 springs.

Do the failure percentages on that!

Sorry Sam.. After years and years of you always talking crap on tsp isn't it time for you to move on?

People on this site are very smart, we all understand that over a run of springs this large if tons of them were failing it'd be all over the forums.

Here's a perfect example for you Sam.

Somebody has another spring failure from a different company and rather than add any help to the thread you just try to stir the pot and ask if it's a prc spring


http://www.camaro5.com/forums/showthread.php?t=132873

The guy obviously said who's spring and that it was a single beehive.

Sadly you couldn't even notice that because you can't see through your hatred for tsp. It's sad really..

Sorry ovenmitt I misses your post. I have good news for you on the .650". We made a update to the 650 lift spring to the next run that will give us a small bump in pressures and give you a liitle more lift capability. I'll get ya some more data when I get back to town!

No need, I still would use your eht .675 spring (shimmed .015) as I doubt the smaller spring could control the valve@ 7200. I love my tsp products

I am not a hater of anyone really but maybe I take it a little personal whenever someone mentions something about the LG cam and you always chime in PTV issues. That to me gets a little old. Maybe you should move on and then others might do the same. Just an observation from someone who reads a bunch.

I read alot too and yourself and Sam always bash this guy.you guys have provided myself and many other members some really good info.I understand that ptv on LG cam is way tighter than the norm and maybe Jason is just trying to keep somebody from making a mistake with his or hers setup.You guys know what it takes to keep that cam from having issues with clearence but Jason deals with alot of people who are not possibly as mechanically inclined and could easily install low quality springs ,wrong gasket or whatever.Then they have a new car with junk for a motor.Cut the guy a break,lifes too short!!!

Wow this has gone too far! If there is a PTV clearance issue then people should be warned, if they still want the cam they are gonna get it! At least know about the issue helps them ask to get it fixed during the installation! Really though I love the TSP Products and their prices, my neighbor loves the LG cam, but if his car makes less power than mine he will never hear the end of it from another neighbor of ours! TSP keep doing what you're doing and customers like myself will keep coming back! If someone is hating on you then you have to be doing something right! Not saying that LG isn't but I would much rather have your stuff! So keep working on those heads so Lethal can make my car faster when I get home from Iraq!! Thanks Jason!!

I've done countless hours of cam research and reading. What I have come up with is if I wasnt to purchase the 231/236 TSP Cam over any other cam on the market I would be an idiot....PERIOD

Years would be an exaggeration. It was 16 months ago when I had my first issue arise with TSP. I had a customer buy a replacement set of your PRC springs and you guys (Matt) sent out a used set of springs that were picked up off the shop floor (cover in metal shavings and at the installed height the spring pressure ranged from 92-131 which was "acceptable" according to Matt). Matt called me a liar over the phone which turned me away from Texas Speed from then on. I would leave you alone if you could manage to stop bashing the LG G6X3 cam. You cant seem to keep your mouth shut about it. It has "p to v issues" yet you are producing a larger cam to compete with it? Smart move.

I was trying to bait you into a discussion about the false belief that your dual spring would keep the valve from contaction the piston if the spring fails. You knew where I was going with it and that kept you from replying to me.
Did your PRC 675 spring keep the intake valve from breaking off the stem and destroying the motor in Gregs car?
Ill answer for you.

No it did not.

Both are great selections. Big cams are going to loss some bottom end. Get a tighter LSA, that helps, or just get gears.
You want a race car, just spend the money. Get dual springs

My current cam which has been in the car for about 4 years is the TSP 228R, but I almost went with an LGx3.

best advice you are going to hear is right here......................... select what cam you want and is perfect for you, then buy the next size larger so you wont have to change it out twice.

either way you go will be a good cam, both cams are excellent from what i have seen on this board. as far a ptv clearance both are large cams with a high lift so ptv will be close on either cam. as tampa tuning said find the right one for you.

I take it PTV is not a problem on L99's with their valve-reliefs?
