Dyno Results: VVT 5.7L Camshafts... 100+ RWHP Gain

**HighHorseman** · 03-16-2012, 03:12 AM

We tested Comp Cam's new HEMI Phaser 274 camshaft with their phase limiter to see what was possible with a real camshaft in the VVT. This is the largest camshaft Comp offers.

The test car was a stock engine 2009 5.7L 6-Speed R/T with our 1 3/4" Kooks long tubes, high flow cats, Corsa cat-back, AFE intake, 180
tstat.

We installed:

Then we tuned her up on our dynojet. You'll hear a little clunking through the gear shifts since the driveline is stiff and has no clutch slippage thanks to a racing clutch from Spec and our fully built T-6060 transmission, one-piece driveshaft from TDSS, upgraded rear and axles along with our GNK Hurst shifter with MOPAR short throw shifter arm. There's zero play in the driveline on this car, lol.

Idle Clip:

The info we've been able to get off this test now allows us to go back and pick apart the gains. Our cam designer at our engine shop, Tony Bischoff of BES Racing Engines, is reviewing the data and custom camshafts will be released shortly. If he doesn't think we can make any improvements to NA stock engines, we'll stick with these profiles from COMP which are really good. At a minimum, we will have custom profiles to release for forced induction and nitrous applications shortly.

For you guy's coming in this Saturday to our Open House at the new Delaware shop, we'll have the car here for you guy's to listed to. She sounds SICK!!!

I think he meant that car versus a 6.1L car in a race...I think.

Update:

Ok, so far we have two solutions for making this package easy for installation of the valve springs that are needed.

Option 1 is we can put the package together with a Manley valve spring, retainer and spring locator combo that is made just for the 5.7L heads. For you guy's wanting to rush to do this package, we can release it right now with this setup from Manley. The cost for these Manley parts is $586.40 and they are available today.

Option 2, which is the way that we will be doing it under the HHP name, is going to take a few weeks for Comp to make us new spring locators in a predetermined thickness which will allow us to use our preferred spring of choice and retain the factory spring cage which is there to keep the valve from dropping incase you ever break a valve spring. Bischoff will be providing the thicknesses to Comp early next week when he gets some parts in from us we just had to order up today and they should run with it pretty quickly. This second option is our preferred method.

Valve spring selection is something that we spend a lot of time on since at the end of the day, a $12.00 part carries a potential to fail and this can be catastrophic in your engine. Back when the Gen3 HEMI first came out we, along with our competitors that were around back then, went through a handful of valve spring failures in our first years with several manufacturers of springs and several blocks took pistons through the side-wall. We're dotting all of the i's and crossing all of the t's to ensure that your risks are minimized since the VVT engines can only be replaced by purchasing a long block from Chrysler and the cost is relatively high. The warranty on a race part is that you'll probably get the broken part replaced but you won't get whatever additional parts gets damaged as a result covered. You break a valve spring and here's a new $12 valve spring but you're left paying $5k for that new engine. We don't want a repeat of what happened when we first went down this road years ago. We have a combination that has performed flawless for us for years now, and option 2 will allow us to use our combination we feel comfortable with.

All that being said, risks are assumed by the customer and we (HHP) do not insure aftermarket parts in your engine even if we do install them. We just guarantee that they were installed correctly. We do everything in our power to put a combination together to minimize your risks.

If you are interested in this package, please email me at josh@highhorseperformance.com and I will get back to you as quickly as I can.

Thanks!

Joshua, HHP

Next up, it will take us a short while to get a set of heads ported by Bischoff but we will be testing out our BES line of ported heads on this test car in the next couple of weeks to see what the additional gains are. Stay tuned on this!
