New cam/longtubes/CAI for road courses
 
3 Attachment(s)
I just upgraded my machine with the following:

ARH longtube headers, high flow cats and cat-back exhaust
Roto-fab CAI
"Track Cam" from Synergy Motorsports (New design, not yet on website. Call them to order it)
Rockers, pushrods, double springs, Etc.
Dyno tune by Synergy

The results were surprisingly good, considering I asked for a cam that was optimized for the beating that engines must endure on road courses. So Rick at Synergy designed a relatively mild cam that won't abuse the valve springs. The lift is high but is less than a typical drag cam, so that if god forbid I miss a shift, my pistons won't become intimately acquainted with my valves :lol:

I'm very happy with the results: 478 RWHP, 445 Ft-Lbs to the rear wheels!

The idle is slightly lumpy, just enough so that there is no question that this bad machine is cammed. It sounds the way a muscle car should. And the complete ARH exhaust system has a nice deep sound. Not as loud as my friend's Borla Atak, but it roars when you get on it. Nearly drone free. Maybe just a touch of drone when cruising at around 1500 RPM, but that's in bog territory and I don't often go there, LOL. Very smooth and well mannered on the street, no bucking or other issues.

I also decided to make it look good under the hood. I've had fast cars before, but the engine bays were always fugly. So this time I went with some Roto-fab engine covers, carbon look intake cover, and and carbon look CAI. Some pieces are painted to match the factory Inferno Orange Metallic paint. Maybe they're not go-fast goodies, but hey you only live once.

UPDATE: I tracked the car at Buttonwillow, and my top speed on the road course went from 113 MPH to 130 MPH. The changes were the engine mods plus new R-compound 315's. I've added a video of the exhaust note below. Click the last link in my signature to see what it sounds like from inside the car, at Buttonwillow :big grin:

That's pretty awesome that you finally found a custom grind that will work with your HPDE's and makes good power. Keep us updated on your events.

Congrats man, love the engine bay btw :)

JDP Tyler 10-04-2013 11:03 AM

Congrats! Nice numbers!

very nice. i was wondering what kind of cams road course guys went with.

1977and2010 10-04-2013 12:33 PM

Nice. I think you'll surprise more than just Boss 302s.

Orange Crush 1LE 10-04-2013 04:06 PM

Thanks guys. The cam is the "Track Cam" custom grind by Synergy Motorsports. He keeps the specifics of his cam designs quiet, but as you can see they work well. I've seen the specs, and it's not as radical as some of the popular bigger cams. If any other track rats want a broad torque band and a cam that will treat your valve springs right on the road course, Rick at Synergy Motorsports is your man.

That's the amazing thing about these Camaros. Such a bargain price, easy and inexpensive to modify, and is competitive with cars much more pricey. A have a friend that I track with that has a GT3 RS and we run about the same lap times, with my Camaro having a slight edge. I will also be running new R compound tires at my next tracking outing, so I'll tell him he had better bring some as well if he wants to keep up :cool:

t&t moyer 10-05-2013 02:27 AM

Very nice numbers! I'll be having a cam done with LTs over the winter and am starting the hunt for the "just right" combination. I'm not into drag racing so maybe I should look into Synergy Motorsports a bit more :) I'm more of a street going back road runner......

Cuda7050 10-05-2013 10:37 AM

When the cam was installed were any supporting components such as springs, rocker arms, lifters or oil pump upgraded? I am curious about Synergies thoughts on the necessity of these upgrades.

SPCBA 10-05-2013 10:50 AM

Nice orange...you def have nice useable power there. Cant wait till next time i see you on road course

Synner 10-05-2013 10:52 AM

Better do springs and trunions for this use/cam unless you want your engine to die. A HV oil pump on a road race car is asking for problems.

Orange Crush 1LE 10-05-2013 02:27 PM

Rockers, pushrods, double springs, sprocket, Etc. were all installed, but no change to the oil pump.

This thing pulls like a rocket. It's hard not to fry the tires. Loving it!

Orange, nice numbers! I'm going to be spec'ing a road course cam soon myself, probably at Lethal Racing during the Texas Fest! Did you have Synergy do the install or did you do it yourself? What makes a cam grind more suited to road course use? Less lift more duration? Do you have any videos of the idle sound?

What is it with an HV oil pump that isn't good for road course use? What type of oil pump should be used?

Fraxum 10-06-2013 09:28 PM

OP Nice to see you have completed your power quest. Great numbers from a mild cam.

Did those coil overs improve your track times? And does your tune raise the rev limit?

Next move that washer bottle out of the way and get a scoop for another 3 HP. :)

And Boss 302s should have been afraid of your stock 1LE.

I think it may have to do with the amount of oil a H/V can pump, starving the pan/bottom of the engine of oil during extreme driving.

Thanks, I was really surprised at the big gains without sacrificing driveability. I'm fortunate that Synergy is 20 miles from me. Rick is well known in NorCal for his engine building and dyno tuning expertise, so I put my trust in him to do just that and he delivered. As I understand it, the trick is to design the cam so that it doesn't abuse the valve springs. Valve springs on a typical big cam that is used on a road course need to be replaced at least every season, or more often if you blow a couple of shifts. The cam profiles on this cam are more gradual. And the slightly lower lift of this cam is to prevent the valves from colliding with the pistons if you over-rev, which is easy to do on the track with so much going on. There's probably a lot more to it than that, I'll let the experts chime in if they have anything to add.

Here's the thing- The dyno results show that I didn't have to sacrifice much HP at all to achieve this improved longevity. This is an impressive cam.

I don't have any vids yet, but it sounds mean. Not extremely lumpy, but nicely cammed. I wore out the stock pads after just two track weekends, so it's in getting track pads and stainless brake lines now, but I may get a chance to video the idle in a couple of weeks before my next track outing at Buttonwillow :biggrin:

Thanks man! Rev limiter is bumped up to 6,800 RPM. Unfortunately I don't have any before/after times with the coilovers, and I'll tell you that it kicked ass stock too. My stock 1LE was faster than a number of Boss 302s at Thunderhill except for this one Boss 302 Laguna Seca. But he came in on a trailer, his engine was modded and he had R compounds. I hope to have a rematch soon, now that I've got a little extra power :thumb:

And I'll be running some monstrous NT-01 315/30-18's front and rear next outing too. Good times ahead!

Ramp rates are gentler, lower overall lift, more duration. Stock oil pump or melling with the stock pressure spring. There is no benefit to running a high volume on these cars anyways. Road racing it will heat the oil more and increases likelihood of running the pan dry. Although in these tanks you will likely need slicks to get there.

Looks like this is the type of cam I'm looking for! Durability, good power, not too radical and nice idle (I'll take your word for it till I hear a video clip, lol!)

Thanks for the info! I'm a newb at cams so I'm starting to do my research before it's time to drop the hammer on one!

Thanks Mike, I see great minds think alike! It's nice to be able to pop the hood and no longer cringe at the sight of the cheap stock plastic engine cover, isn't it?

Agreed! I get a lot of compliments when I open the hood!

What's sad is I have the same Covers as you guys, just in CGM, and when I saw your car at the Fest, I got jealous! Everything under your hood is tasteful and looks like it should be OEM. Well done sir!

Jeez! You really been upping the ante.
