TR 224 cam users, how long have you been running it? I'm getting ready to do a cam install and really like what I hear about the TR224/224 112lsa. Reliability is the #1 concern of mine, how many of you guys have been running it for at least a year now? Any problems...? Also, do you still love it or would you get something else if you did all over again and why?

Re: TR 224 cam users, how long have you been running it? I have the 114lsa in my 00ta only about 4000 miles but over 100 passes down the 1/4 mile and I love it.

Re: TR 224 cam users, how long have you been running it? Cal, you speak the truth, I should have worded my question better.
How is the valvetrain doing for anyone with 20+ k miles on their TR224 comp 918 spring combo (or similar) doing?

Re: TR 224 cam users, how long have you been running it? 400 miles and no problem here 
:p
From what I understand w/a TR224 type cam expect to replace your springs around the 20-25k mark...
I'm running a TR224 cam w/TEA S2 5.3L heads (comp 987 double springs) and plan on replacing the springs every 20K miles... better safe than sorry and a few hundred every 20k miles isn't that expensive...

Re: TR 224 cam users, how long have you been running it? Had mine for 11K miles and 7 months. No problems here 
I make well over 430 to the ground and over 400 tq as well. In hindsight, I'd stay with this cam

Re: TR 224 cam users, how long have you been running it? It sounds like a great cam for a good compromise of reliability, driveability, and power.
Anyone else with 1-2 years and 20,000 miles? I'd like to know who has HAD to change springs and when it occurred.
Thanks for the responses, keep 'em coming.

Re: TR 224 cam users, how long have you been running it? What I heard is they only need to be checked every 20k, not necessarily replaced. There is some kind of tool that allows you to check for spring presure; if it is too low you replace the springs. The other thing is with stiff springs, they say most people break them by not letting them warm up before reving the engine way up; they tend to be brittle when cold.

Are there any reliability issues with double springs?

Re: TR 224 cam users, how long have you been running it? TR224/114 w/ 918's here. Over 11K, 75 1/4 mile runs, and COUNTLESS street runs with ZERO problems.
Its in a full interior, lowered TA, A4, SY3500, 3.73's, on Nittos, shifting at 6600 (have even bounced off the 6800 RPM rev limit quite a few times - OUCH!!), running high 11's/low 12's. It is VERY streetable. I would recommend it to anyone looking for a streetable cam making nice power.

Re: TR 224 cam users, how long have you been running it?
Are there any reliability issues with double springs?
I was just wondering because it seems those are the only springs to go with when running big lift cams ala G5X2. For awhile there were issues with single springs failing and just thought why bother with single springs and just go with double save yourself the hassle, have better reliability, longer valvetrain life (from a spring swapping standpoint) and not have to worry about the springs when going with a bigger cam.
But if Jason from TR says to stick with 918's theres got to be a reason for that. Hopefully he'll chime in.

Re: TR 224 cam users, how long have you been running it? The duel springs handle higher rpm but I haven't heard of them lasting longer than good singles. Paul said Jason takes his 918 equiped motor up close to 7000 rpm, so I figured that was good enough for me.

Re: TR 224 cam users, how long have you been running it? Actually we have gotten more usable RPM out of our cams with the 918's properly installed than any other spring we have installed. The REV Dual springs that certain other vendors are pushing for use with their oversized cams quite simply won't spin as high as the 918's. IMHO these vendors are pushing these springs because they either haven't properly tested the 918's or really don't know what they are doing. There are a bunch of reasons for this having to do with this such as the resonant frequency of the spring and valvetrain weight. Seat and open pressure are only a small part of the equation. In addition the 918 spring theoretically has nearly an indefinite life in the applications such as our 224 cam. Jason tested some of the first prototype 918's before they wer available for sale. After 5000 very abusive miles they had lost ZERO pressure. We haven't seen that from any other street spring. The main reason for going to a double spring is that if you have a coil failure you still have a backup to prevent a catastrophe. this is a safety benefit not necessarily a performance benefit.
Yes there was a rash of failures with the 918's in the past. These failures were related to the processing of the metal in the springs. This had nothing to do with the spring design, which in my opinion for street applications is without a peer. Comp has since modified and improved the way that the 918's metalurgy is processed. Since these processing changes have been made we have had no failures with the 918's.
Our current cam offerings with the 918's should last quite a while. However with any performance valvetrain it isn't a bad idea to periodically check spring pressures.

Re: TR 224 cam users, how long have you been running it? Hmm thats good info about the 918's Geoff, I believe I am going to need to buy a new set of springs soon to replace the Isky's on my heads so I'll have to decide. I currently do have the 918's on my stock heads at about 20k miles and I have had no failures.

Re: TR 224 cam users, how long have you been running it? Geoff couldn't have put it any better. I have run 918s in all my hydraulic setups and will continue to do so. We have used alot of other spring setups with the TR line of cams and have yet to find a spring that better controls the valve past peak hp.
We were using the 918s with a set of GTP stage 2 heads going to 7200rpm very smoothly in my car a couple months back. I have dyno sheets I can post if anyone is interested. Remember, this was with heavier than stock 2.02/1.57 stainless valves. Valve control would be even better with the stock weight valves.

Re: TR 224 cam users, how long have you been running it?
Why do the TR/GTP Stage II's come with the 987's? Strictly for the safety aspect? Just curious.

Re: TR 224 cam users, how long have you been running it? I haven't been running mine personally for that long, but I've installed several that have been on the road over a year w/ 918's ... no problems to report yet...

Re: TR 224 cam users, how long have you been running it? I wish I could remember how many miles I had on my car when I installed my
TR 220 /918 combo (pre blue stripe). I have 82k on my 2k1WS6 now. I am going to guess I have about 30k on the 918s now. I 've broke one flex plate and two rear ends and a tranny but my springs are still good lol.
