just wondering where most of you make peak HP at. Espically the 224/224 114 cam owners out there.

6300? 6400?? more? less??

QuickZ

Since we are in the topic (224 cam) I would also like to know what are the advantages and disadvantages of a 224/112lsa cam over a 224/114 lsa cam? I have a M6 car and everybody recommens the 112 over the 114... even though the 114lsa idles better..can somebody explain..please.TIA

I peaked at 6100 but held within 10 HP of peak HP all the way to 6600 with my 224/224 114. (Locked converter dyno <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> ) Probably had 4 degrees of advance, but I didn't get the cam card.

Heads & exhaust can effect results.

Quick: 112 should peak a few HP more, but drops off a hair quicker. Most 112s end up with more advance than a 114 so they feel torquier.

Here's my graph, the dyno was through the 3" grot Y with cats. It's a nice cam, but I'm getting greedy. Time for an upgrade!

Thanks ragtop,
Do you guys know if there is much difference in idle between the 112 and 114 on a M6 car. Which one performs better at the track and on the street?TIA

QuickZ- the lower the lsa number the lopier the idle, quicker the rev, which in an A4 car will require higher stall due to loss of vacuum. I think the lower lsa will also give a few more hp at peak then higher lsa's.

With the 112 LSA your torque will build faster in the midrange (below 4000 RPM). This is great on an M6 on the street or for auto X. At the track,once out of 1st gear you never see below 4000 RPM, so 112 vs. 114 LSA will make very little difference. <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

Harold mine peaks at 6200-6300 rpm. Curve is fairly flat from 6100-6500. Drops off quickly after 6600.

My torque peak is right at 5000, and peak HP comes in at 6300. That's with a 114 LSA

My <img border="0" alt="[hail]" title="" src="graemlins/gr_hail.gif" /> SRP 224 XE-R has the following peaks:

418 rwhp @ 5,900 rpm
404 rwtq @ 4,800 rpm

My dyno graph shows the same rear wheel horsepower and torque at @ 2,300 rpm my basic bolt on set up had. This was where my dyno graph started. Drivability is excellent. Car feels very strong down lown.

I'm very happy with the cam and the powerband.

I think my stock clutch slipped on the 418rwhp pull because something was stinking on the dyno. I think the cam would peak just a tad higher with a good clutch. My guess is 6,000 to 6,100 rpm

Oh yeah, I think the TEA heads are pretty decent for the cost too.

TR224 on a 112 LSA here. Peak at 6,000 and held flat until about 6,600. I'm shifting between 6,600-6,700 and seeing about 5,000 extension with a SY3500 and 3.42's.

I have the X1 cam from MTI. I have a good flat TQ curve from start to finish. My HP starts and doesn`t stop intil 6300rpm. Here is what I have!

TQ HP
3500-360 4000-280
5000-382 5000-360
6000-360 5500-390
-------- 6000-410
-------- 6300-414
-------- 6500-410

This is with a A4,Vig3200 stall, 12-bolt, and the timing set at 23 degrees for spray. I could have gotten more with alittle more timing. As you can see my TQ curve is almost as flat as you can get, and my HP just keeps on going, MY shift points are right at my peak hp. MTI really like this cam. She pulls like a mother the more you get into it. Love it!
230 227 .591 .571 112
Idles good, runs really we`ll. I have a sound clip of my car exhaust and the dyno sheet if you want to hear and see! Let me know. Good Luck! <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

99 Black Bird T/A,

You are making really nice numbers!!! Especially at such a low peak. That baby is going to run a serious 1/4 mile. Nice setup.

up2late76

my 224 is a 114lsa. my numbers peaked at 6100 and started to drop off after that...

with the m.t.i 222/222 566/566 112 hammer cam,r.g.r st2 heads,12bolt and most all the other goodies,i peaked 424.1 hp at 6,400 rpm's. it held strong to 6,800 then started to drop (slightley). peak tq 407.4 at 4,800 rpm's then started to fall . this cam is GREAT ,it's not real lumpy,drives smooth and when you stomp it the hammer cam HAMMERS. i know it's not a 224 cam like you asked about but it's kinda close.

98TAauto:
Remember that the RPM band will be moved up or down by advancing or retarding the camshafts installed intake centerline (ICL).

Many manufacturers build 4 degrees advance into their performance cams to lower the RPM band.

When asking where the power peak occurs, it is also important to know if the cam timing was advanced or not.

I installed a used 224/224 114LSA cam from MMS which they intentionally ground 1 degree RETARDED. I had to use a multi-keyed timing set to advance the timing. Otherwise it probably would have peaked over 7,000 RPM.

My old 224 cam was a 112 lsa and would peak at 6100 and stay flat until 6500 then it would drop.

My old TR224 ( 112lsa ) cam peaked at ~6100rpms also. This was with stock heads.
