Default Bit The Bullet, Tell me what ya think of my coming bumpstick

224/224 on xe-r: I know everyone has one, damn 3.42s
On a 110lsa: Thumpity Thumpity
565/565: Don't trust the springs enough to push it
4 Degrees advance: Everyone is doing it
918s with Titanium Retainers: Might as well
7.4" pushrods: Stock and all

What do ya think? I chose the 110 because I like a good thumb and also like the fact that it brings peak power and torque down and creates more peak power and torque. 565 lift because I don't trust the 918s past that and don't think there is power to be gained beyond that on stock heads (my opinion ofcourse). 224/224 because of those damn 3.42s and the desire to not spin my motor past 6600. Titanium retainers for piece of mind(less weight on springs means less stress on springs). Pushrods, you know the drill. I have ls1 edit so there will no tuning problems. Might need to drill the tb some. Only time will tell.

P.S. Will be ginin' ya a holler in a couple weeks there Stu.

Should be just about perfect. The only thing I don't like is the 918's. Even at that lift. Good luck!!!!

I dont think it will be bad,but I prefer the wider lsa than 110. a 110 might make more power but on a stick a 114 seem to have a longer powerband.

Check out Comps new spring (don't know the number) for higher lift cams. I'm running 573/580 and no problems yet. LPE set it up for me. I asked if they put the 918s in and they said, 'Nope, their new ones...' <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> . They didn't elaborate, nor did I care <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" /> .

From the spec's it sure looks like an XE cam instead of an XE-R

XE-R's all have .580+ lift

Some reps at Comp will tell you it's an XE-R when it's actually an XE. Had this happen to me.

I have a jpeg of a cam chart from Comp to back this up, but I don't know how to post or host it.

Check this website in the cam section near the bottom and you'll see the chart.

Maybe someone can find the link to this on Comp's sight where the chart is easier to read.

I had the cam custom ground on the xe-r lobes. You are correct in that most xe-r grinds are 581 lift.

Personally I think you are going to peak pretty low and have a big drop in power after peak RWHP.

4 degrees advance with 110LSA is too much in my opinion. Your intake valve is going to close way early. I would have retarded the cam 2-3 degrees with that LSA.

It'll sound nice but I dont think it is going to make a whole lot of power above 6000rpms.

cheers,
Chris

ps- FYI: My car with only 360cubic inches peaks at 6300-6400rpm with a 230/230 112LSA cam with zero advance ground in. Part of that is AREs porting (Maximizes area under the curve)

Good cam... except the L/S will make for a peaky *** power range..and a short one too boot.

It will thump with the best of them... but why cheat your self on the lift and the power vs, RPM range?

Go back to the 112 or even 114 and use standard .581 lift... i bet you would be happier.

Cam is already ordered. Do really think this cam will peak before 6000. I do have stock heads which would keep the power band higher I would imagine. I am going to try it straight up (4 degrees already ground in so 4 degrees total advance) and see what happens.

Raughammer, do you really think there is that much power to be gained by going 581 lift verses 565. Many thunder 224 owners have made 400rwhp with a cam with less lift then mine with stock heads. I do think it will tear up springs more with 581 which is a piece of mine thing with me.

P.S. Does anybody know how to get an ASP pulley off. I can't use the same puller I used for the stock balancer can I. We will have an impact gun when doing the install.

Hey Nick are you planning to do the cam install yourself? If so, shoot me an e-mail me at buschman_007@hotmail.com. I'd really like to help you out as I'm planning on doing a cam next season.

Let me know bro.

I agree with Chris. 110 LSA with 4 degrees of advance is going to really put a hit on the upper end power. I would run it at 0 degrees to 2 degrees retarded if you have the option of installing an adjustable timing set. The better option would be to try and change the order specs and widen the LSA to 112 and at most 2 degrees of advance in my opinion.

Jesse at SRP actually checked the cam on his cam doctor: The cam has 4.75 degrees advance. Instead of the Intake Centerline being 109 it would be 108.25 as ground. This is fairly common. <img border="0" title="" alt="[Sad]" src="gr_sad.gif" />

JMHO

Your 110 LSA w/4 degrees advance would be on a 106 intake centerline if your cam is perfect. However, most cams are off a little like mine was your 110 LSA w/4 degrees advance might ended up with 4.75 degrees advance and a 105ish <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> intake centerline starts looking very possible. This will pull the power band even lower as previously mentioned.

What are the grind numbers Comp told you? They told me exactly the same thing they told you then provided a grind number for an XE cam instead of an XE-R. No <img border="0" alt="[bullshit]" title="" src="graemlins/gr_bs.gif" /> That's what they did Check the grind number there is a very real chance your about to get an XE cam instead of the XE-R you requested. The lift is determined by lobe selection not the other way around. Won't hurt to check in either case.

As a 224/224 XE-R only flows ~2 percent more than a TR-224 why not just get a TR-224 if you want a fast ramp cam with ~.565ish lift? The only real difference in the two cams is the XE-R has a tad more lift so it flows a hair more than the TR-224 does. Take out the lift on an XE-R and you have a TR-224 like cam that may or may not work as well as a TR-224. It's not going to work any better that's for sure because it's the samething, assuming Comp actually delivers what you requested.

Call Paul at Thunder Racing, I bet he can help with getting a nice custom TR-224 cam on the LSA you want for your car. Seems to me the TR-224 on a 112 LSA would be possible cam for your application.

Best wishes and good luck.

Just my opinion, but you have stock heads. That cam with a .581" lift is not going to be very compatable with your heads. Jeeze, your stock heads stall out [way] before .581" lift.

Why not get something in the .550"-.560" lift?

Make sense?

Read people, read. First off, the cam has already been ordered. Second, I requested different lift then the typical xe-r grind which is 581 (I chose 565 because of head stalling and 918 issues, plus I will be getting stage 2 heads in the future). Third, I don't want to be like everyone else with there 224/224 112 or 114 lsa cam. I thought I would try something different. There is alot of theory here talking about what the down sides of this cam are. Any actual numbers or real experience to back this up. I am still not convinced that anyone actually knows what lsa does to the power band. Half say it raises it, half say it lowers it.

P.S. Sorry if the post seems bitter, I just got back from the bar with a b@tch that decided to yack in my car even know I asked here 30+ times if she felt o.k. and offered to pull over.

Did you read my reply? <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Again, do you have the grind numbers for the cam?

I have first hand experience directly with Comp on exactly this same issue. 224 XE-R with .568ish lift I talked with two different reps. I asked for exactly the samething. Comp gave me 3715 as the grind number for a "224/224 XE-R cam with ~.566 to .568 lift". See the link to a copy of Comp's own chart and see this is actually an XE cam not an XE-R. If you were told the same grind number I was you will get an XE cam instead of an XE-R. This is why I asked, "What grind number did Comp tell you twice so far."

See the link for the chart:

http://home.insightbb.com/~ominousvette/compcams.jpg

Hey, it's your car, your cam, your ears, your choice do as you please don't get the cam checked etc, I fully respect your choice whatever it maybe as it's your engine. Like the topic asked, I'm just telling you I think your coming bumpstick should be checked to make sure it's actually what you asked for.

Wrong cam (if it is wrong we don't know as we don't have the grind numbers to confirm or dismiss my suspecion and the cam hasn't been on a cam doctor) isn't a big deal BEFORE the cam goes into the car.

Have the cam checked on a cam doctor if Comp didn't give the grind numbers. Heck, have it checked anyway on a cam doctor so you'll know exactly what you were actually sent.

The lobe profile determines the lift not visa-versa. In any case, XE's are excellent cams and I'm sure you'll be please even if it's turns out not to be what you asked for. <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

Dyno charts, I saw of the B1 (114 LSA) vs T1 (112 LSA) showed the T1 made power a little sooner and lower than the B1. All the data I've seen indicates lower LSA push the power band down a little. All the data I've seen indicates wider LSA's idle better, flatter the curve some but push the powerband a little higher.

I don't have a link to that chart maybe someone else does, as has Nineball posted it several times.
