Tsp 224r

Is this cam 224R(XE-R lobes) worth the beating the springs will take to gain a few more hp under the curve vs. a TR or TSP 224 with XE lobes?

how much do you drive the car?

the springs would probably still last 30k miles. for me that would be over 4 yrs probably.

so $200 in springs every 4 yrs...not horrible for an extra 10-15hp (guess)

Its what a .022" difference? Just get the patriot gold spring kit instead of the 918's and don't worry about it.

Yeah, I just bought the Patriot LS6 style heads and they come with the gold dual springs. I just don't want to have to change the springs every 10-15k. 30k I could live with. Does anyone know the difference in spring life between the XE and XER 224 lobes?

It varies with how you drive etc. With ANY aftermarket cam you should check your springs at regular intervals.
W/those patriot heads you should get the patriot 226/226 cam if its cheaper.

I would, but I live in CA and need a smog legal cam.:cry:

The 224 has been known to pass, but still may not. It is boarder line.

Personally, I don't see why more CA people don't run the CheaTR. It's designed to work better with the restrictions you'll face.

From what I've seen here in CA, the 224's on a 114 pass easily. This is a very popular cam here. Now the 224/228 on a 114 is definately borderline, but most even pass with this cam on a good tune. Sometimes I wish I lived where you do, so I could run what I really want to. I just solved my problem today though.......and ordered a custom cam.

Cool, what specs and who's grind?

Ive got a 222/224 581 on a 114+4 ready to go in, I live in socal and hope I pass. Got the car smogged yesterday so I have 2 years before I have to worry about it.:eek:

It's a 93pony custom. It's a 224/224 .58x"/.56x" on a 114 LSA with no advance. It'll make more peak and "under the curve" power than the OTS cams. I'm just bumbed I have to wait a couple weeks to get it.

that sounds like a good combination, your going to have to get a dyno chart up on here so i can see what it looks like, i wanted to run something similar to that

I tune my car with hp tuners "on the fly", so I've never dyno'd. I'll probably do the same after the swap. I could stop by force fed and have it dyno'd....I am pretty curious. I'll try and dyno it and post up. There's a guy here that dyno'd a 93pony cam, with midlengths and stock heads at 400/395. I'm thinking I should make some nice #'s with the addition of stage II heads 10.75:1 compression and longtubes.

How is smog in Scottsdale? MY friend just moved there and want's me to move. I heard they are pretty strict like CA also. Do they have the roller dyno sniffer, or just OBDII check?

just the obdII scan, they dont do a sniff test or tailpipe emisions... i was just at pro dyno and they said they had 800hp camaros passing emissions with flying colors lol

so they arnt that hard
