This Saturday, possibly Friday or part of it. Most likely just Saturday though. Shouldn't take but a couple hours. Some friends want to come over and help though, so I'm sure there will be a lot of wasted time with us talking and screwing around.

 

Hell yeah. I've been specing out my own cam based around those specifications that you got from DaSuprSlo, except I'm thinking about a 226/226 or 226/228.

Can't wait to hear/see results from this. Pleeeeease for the love of god get a good sound/video clip or two haha.

 

I don't know how to make clips and put them on the computer. I'll let you know how it works out though.

 

No worries on the hijack, I'm enjoying the reading

 

wow...didn't notice it before, but you got quite a set up awaiting you...

 

Yea, just purchased a set of LS6 valves for the heads. I have a few things I'm still looking for though. I'm pretty excited. When it all comes in, i'll be doing a post of progress with pics. Thought it would be very helpful.

P.S. if anyone in the Northern cal, sacramento area enjoys projects, let me know cause this is gonna be a big one!

 

Well guys, it's in and running. I didn't have work today so I put it in this morning/afternoon. It took around 4 hours (no spring changes). First impressions on the cam. The first thing I noticed was more valvetrain noise. Even though my tsp cam was bigger it had softer lobes. The second thing I noticed was the idle. It was deeper and sounded much cleaner. Still the same amount of lope but smoother With the windows up and the doors shut it is a little big quiter and deeper. Well on to the test drive. I drove it a little easy for about .5 miles. Then I got on it a little. The powerband is way down from the tsp cam. The rpm's don't climb like the tsp cam but it seems like it pulls more. The sound is much more smooth and deep instead of screaming. I took it to 6,000 in second and it was pretty nice. I feel like I lost a little top-end power but that could have been from the bad low end hard pulling top end of the tsp. Since the transition is smooth from low-end power to the top-end it's harder to notice. Where as my tsp cam had a definate increase in power at 3000rpms. It was almost like a small shot of nitrous or a turbo car building boost. Now the new cam pulls from about 2000-6000 (haven't taken it past that, and probably won't) Overall I am very pleased. Not near as much surging, and the sound is a lot better. Overall the car just plain runs a lot smoother, not just at idle. I really like the low-end on this cam. The rpms won't jump as quick but I'll be going faster, if that makes sense. I guess the only way to explain it is torque. I can't wait to see how this runs with a different tune than the old cam. BTW just as a side note the tires break loose at 2500rpms in second gear. I'd have to be at 4+k to break them loose with the old cam. The thing that really gets me is the sound. It sounds SO much better normal driving and WOT than the other cam. It was well worth the swap for me.

 

A little tune and a dyno graph would be nice.
Congrats, keep the info and feedback comming please.

 

Tune will be coming in a couple weeks, not sure yet when I'm heading down to Tampa.

 

I'm getting a 224/224, .588/.588 110+0 (cam Motion) for my vette with stage 1 TEA 241 LS1 casting (ported stock valves). 11.5 SCR +
Should be interesting to compare curves on those cams.

 

only difference is heads. I don't know how well you can compare curves with aftermarket heads...

 

How well do you guys think a 228/228 .580 .580 110LSA would work? I want the characteristics 777 just described, but a little more lope/overlap and pull a little bit more(I want peak power around 6100-6200 so I can shift around 6300-6400 maximum).

Awesome results, can't wait to see what happens after a tune.

 

Hmmm..... A lot of cams with timing events that result in tighter LSAs lately...

Hey Pred... Why not a subtle reverse split on this combo?

Ed

 

This thing lopes a lot. It just is deeper instead of poppy like my tsp231 cam. The cam's peak power should be around 6300 and carry out to 6500. Let me get this thing tuned. Get a graph, and possibly get a sound clip and then see what you think.

 

yeap, I could. I allready run a reverse 224/220 116 with geat results. Being A4 I think this no split would be a little easier to tune.
I'm no wizard for sure, just starting to experiment.
what would you suggest?

 

Did a few 228-224 profiles for the GTO's with stock heads and they rock!

 

I have PRC 5.3L, stage 2.5 (2.04 int/1.585 exht), modified MACs, 3" custom tubing into Magnaflow.
So yeah, reverse would work well.

Besides that tight lsa 224, there is a reverse on the market that I'm curious about trying out. The old venerable TR230/224

Also, how do you think a cam like the 228/224 but more like this

228/226, .56x/.57x 110 lsa
with XE lobes on intake and XE-R on exhaust
with VE's as follow .050'
4-------Intake Valve opens - IVO
44------Intake Valve closes - IVC
43------Exhaust Valve Opens - EVO
3-------Exhaust Valve Closes - EVC
110-----Exhaust Centerline - ECL
7*------Overlap

Could you expect relatively good trq output. Do you thing the EVC is too early VS IVO ? any negative effect?

 

Looks OK but not enough lobe area for my taste. Also, without any data on these PRC Stage "?" heads, it's only an assumption...

Got to be quiet for now.. PSJ will ban me if I say any more.

 

Thanks Ed.
