I'm currently running the 211 cam in my car with moddifed TPI setup. I'm thinking of switching to the HSR. Has anyone had experience with this combo or know anyone who has? So you know I 'm also running Trick Flow heads, vigilante 3200 stall conveter, and 3.23s.

 

I was thinking maybe running 3.73s with the HSR and the rest of my combo might help.

 

That cam is small for a HSR. It'll run ok, but nowhere near optimized. I suggest a 224-230ish cam w/ the HSR and definitely the 3.73's.

BTW, what do you run w/ the LPE 211/219 and the TPI?

 

I also would like to know what you ran with the LPE 211 cam??

 

click the green banner. i just did a dyno today with the HSR on my engine with the zz4 cam. the dyno shows the compare from the SLP fully siamesed runners and Edelbrock base to the HSR.

here's the link: http://stealthram.com/dynoresults.html

 

I'm just now replying . I didn't even get an email. oh well.
I finally just got my motor broken in right now. So I should get to the track very soon. I'll post the results. Just so you guys know along with the 211 cam I'm running some Trick Flows(a little port work on the intake side), accel base and SLP runners. It has a stock 48mm throttle body and 3.23s. I'm also running a 3200 stall vigilante. With the stock motor with just a few bolt on I was runnig 13.9@100 and 12.7@108 w/150 shot.

 

Better get some gas to that motor or you gonna break it

Not to mention that jagged curve shows some pretty decent knock retard, so detonation is occuring.

 

well that motor is long gone already. 383 went in last week. on that particular dyno the #6 cylinder had 60 psi in it. pulled it apart last week. head gasket went between #4 and #6. but before i pulled it, i add fuel t othe upper rpms and gained .2 in the 1/4. just got the 383 to idle by messing with MAF table 1. oh and the jagged lines aren't knock retard. i control the timing through the holley prostrip annihilator ignition. i bypassed the ecm for timing. being extremely lean causes those kinds of lines because of lean misfires. that and sometimes having dynos up in the air instead of i the ground you get the dyno shaking around.

 

I agree w/ BuckeyeROC. W/ those heads and the StealthRam that LPE 211 is too small. I would run at least a 224/230 w/ that setup. W/ 3.73s and that converter, I bet you could see very low 12s w/ that setup.

 

I choose the 211 cam because I planned on keeping the TPI setup. Now I want somthing different. I don't feel like yanking the cam out since I just put it in. Any other suggestions as far as intake choices with that cam? I was also thinking SuperRam or AS&M runners.

 

I finally went to the track today. I managed to run a 13.6@104 on the first run and a 13.5@102 on the second. Both runs had 60 ft of 2.0. I know the wind was gusting over 30mph and it was against us so I know that could have affected my mph on my second run. I definately should be a little faster. before the heads and cam I was pulling 1.8 60fts on motor and spray.

 

If anyone is still following this thread I managed to run a 12.9@104 tonight.

 

Nice, way to bang into the 12s.

I imagine you should be able to top that thing out close to 106 or a bit faster. With a good 60ft time you should be really looking for 12.50s.

 

nicee if you ever decide to switch cams, i'd go with comp cams 08-503-8... thats the one they recommend for the HSR

 

I pulled a 1.7 60ft. on that 12.9 run. I was thinking of doing some port work on the runners and base and maybe step up to a 52mm throttle body. Anything else anyone could add to get some more out of what I got now? I have a stock susoension other than spohn LCAs. I'm also running stock 3.23s.
Oh by the way what's the specs on that comp cam?

 

i have the 502 on my car since im running the stock tq converter. ill upgrade to a larger cam after i install the HSR, new tranny and stall converter that'll match with the HSR

08-502-8 Comp Cams "Extreme" Hydraulic Roller Camshaft
218 / 224, .495 / .502 112 LSA
High performance application, largest with stock converter, noticeable idle

08-503-8 Comp Cams "Extreme" Hydraulic Roller Camshaft
224 / 230, .502 / .510 112 LSA
High performance street machines, 2000+ stall, gears, choppy idle

i'd get 3.73's with the 503 cam, and a 2400 stall if you're running TPI

 

Were those 13.9 @ 100mph runs before the cam/heads/TPI upgrades? Cause you are confusing me now.

Although 12's are nice!!

 

With the stock heads and cam with a few bolt ons I was running 13.9@100. With a 150 shot I went 12.7@108
After the heads and cam swap I went 12.9@104 N/A. I also found out that I had three pistons busted up a couple of months later. Something did feel funny on the run but couln't figure it out. turns out the ring lands were cracked up.

 

Im amazed no one has mentioned how beautifully streetable this cam is, lot nicer than a hot cam or something pushing into the 220s on duration :-)

I drive 300+ miles a week in my Formula and most of the time its fun(why im here) .. I would think this would make me qualified to drop my 2 cents. His may never be "optimized" to the nth degree, but im betting once he works it all out and gets a good tune done(diy prom plug), It will be a very fast easy driving car.
nothing wrong with that as long as its fun to him.

Have some plans in the near future for a slighlyt larger motor and converting to the stealthram when it becomes available for vortec heads also(running sdpc base for now). Im settliin into a cam(it may be the Comp grind) choice in the low 220's on the intake and 230ish on the exhaust around a 114 LSA (possible artificial aspiration in the future). Not big by anyones account, specially for 383 and up but trying to make up for some of that by meticulous assembly and attention to all the little details from the top to the bottom. Do not plan on spending a fortune, but taking the time to do it right. And yes Im talking about pounding out over 300+ miles a week on this one too.

If your only mode of transportation, u some times need to step back and take into account how the car will truly get used.

Less can be a lot more specially fi your stuck in bumper to bumper traffic on I-80 in Chicago for 3 hrs straight :-)

Yes I will admit the 211 cam does seem a little on the small side to me, but I know what kind of low speed driveability there is on large and small cams and somewhere in the middle cams as well. I can live with some tradeoff, i wont put up with a snarling hardly idleing anything so I end up erring somehwere in the middle.

Just my two cents to be taken with a grain of salt

Yes I will admit the 211 cam does seem a little on the small side to me,

Then the Z06 must have a dump truck cam. Its around 204@.05" on the intake and that car is no slouch. 'Course duration doesn't tell the whole story.

I mean look at this guy http://www.geocities.com/z06_racer/ good stuff!

ok I'm way off topic sorry

That is why i said to me, I would have gone somewhere in the middle of my hotcam and his 211. The "to me" was the key part, and no, the Z06 is not a large or rowdy cam whatsoever(then again look at the flow numbers on the accompanying chy heads). It is part of the best engine to ever roll out of a major manufacturer however with over 40 yrs of technological improvements over our engines. The most critical element here is that none of it applies to this post as we are talking conventional small block chevy wisdom here.

Thanks

You know Jeremy, I'm almost wishing I went with the LPE 216/224 cam. Not that the 211 cam will make me slow!

Though, i don't have nice aftermarket heads, or ported to **** L98's so I don't think 12's are in this motors future just yet. Perhaps another day. A mid 13' would be nice.

 

Your still running LTR setup Bill. That car should be really fun to drive, just get into tuning, you know ill help you out when and where i can..


yours shouldnt be remotely hard to tune, to get perfect yes, to make it really driveable should be pretty easy.. Nothing wrong with a little smaller if you drive the living wee out of it on a daily basis. Your one of the few here who know I pound out 300+ miles a week on my car

later
Jeremy
