A larger Cam Will require More tuning than most mods since it alters the intake vacuum.

I Have in stock.
ADM, race and street
Airaid
AFE which has not been tested
LMR
RotoFab
Hennessy

I am also Dealer for Cold Air Inductions taking orders for first Production run in 4-6 weeks.

I will Be selling FastLane and New Era OTR Also.

Pretty much Any Performance Part out there

Thank You.

Ted.

Thanks again Ted, just for the sake of clarity, does anything typically have to be done with the O2 Sensors from a calibration perspective. My understanding, and I could be way off here, is that when you replace the headers the location of the O2 Sensors can change, just like the positioning of the MAF with a CAI, and with a higher flowing exhaust would it not throw the O2 Sensors calibration out of whack as well.

The simple answer is NO.

The computer learns what is called Transport delay time.

The time in which it takes for the O2 sensor the see the change in the injector pulse.

I am sorry Halltech did not have their intake ready to ship for the shoot out. I just put the second carbon fiber intake they built on my LS3.
Put it on the dyno and picked up over 34 hp, from stock air box with cam and headers; 455.42 hp to the rear wheels.

Jim had recommended sweeping the intire MAF code by 116% because it would flow 16% more than than stock. I already had a tune for the cam
and stock airbox which made 421 hp and the extra 16% was close.

I should caution that I ordered the oversized MAF version with the 102mm MAF and larger tube because I have a Thunderracing custom cam with
231/247 duration and 113 LSA. This is a tune only intake because over sized. I did not test any other intake and the large increase was probably partly caused
by the stock airbox starving the cam.

A copy of the dyno graph is attached with under the hood picture. We let off at 6,500 RPM, before it hit the rev limiter, on the first pull, because it was
starting to lean out a little. The final AFR was close to 12.5 and lost one hp, maybe because hotter, but picked up some torque to 421.46 lb. ft.

A dyno run with headers and camshaft has no relevance to the testing Ted did on a STOCK car. You should put this in the Halltech thread.

How do they keep it from sucking in hot air from the engine bay?? Maybe cause they're cheeseheads they think everyone gets cold air temps all year round haha

ps I'm also a cheesehead

Our heat shield prototype is at our plastic mold shop. All customers will receive one within 2 weeks. They come with the kit at no additional charge. Heat shields are a must. Our testing show a 20 degree delta between OAT and IAT without one, and at a stop light, that can go to 40 to 50 degree delta when the fan kicks on. Our heat shield kept that delta within 4 degrees, with some heat soak accounting for that small delta.

We were Johnnie come lately to this forum, with our unit not ready for the test done by the forum.

It looks like the testing was very fair and comprehensive and as accurate as Rear Wheel Chassis dynos can be.

Since we were late to the party, we have started our own thread, with four separate dynos now in (three from yesterday alone) Each dyno was done independently of Halltech, except the stock only test, which was done on our Camaro, while we watched on the sideline.

I took a double take when I saw his intake. I remember looking at your thread and noted you had a enclosure. I thought Hennesey was the only major one not to have their filter in one. I must say the CF looks great, just a little too pricey for me to snag one. I do like the way you incorporated the radiusing into your intake though.

On a side note, I see that Nuptu's AFR is pushing 13.5:1 at max load. How high can you go and still be "safe". I was under the impression that you wanted to keep it a bit richer than that, to avoid lean conditions. I would think that a good 20-30 degree cooler day could easily push those AFR's in the 14 range.

Now Now no AFR it dos not make a deference or dos it.

They did the tuning, but I agree that 12.8:1 when running E10 is much safer in most conditions. During the fall here in WI we have run our prior Z06 at 13.2:1 and logging showed very little knock retard. 13.5:1 is still too lean for me even running E10. The small amount of ethanol in the fuel helps with knock retard, but that is pushing it.

Ethanol carries 30% oxygen with the fuel, so the stoichiometric air fuel in closed loop is 14:1, with the ECM correcting to 14.7:1. Your always running on the lean side with this condition.

My recommendation for E10 is 12.7-12.8:1 air fuel ratio in Open Loop.

BTW, our 13:1 E85 burning Z06 built by Katech runs 9.8:1 in closed loop and 8.5:1 in open loop. Mileage on the highway is still 23 mpg! 105 Octane straight from the pump. I did all the tuning.

It does when it's relevant. Bringing it up just to bash a test is WORTHLESS, as in your case. I was merely asking a question as to why they ran his TUNE up to 13.5. If you care to chime in on why they might have done that, then have at it. If you just want to go around to different threads TRYING to find something that MIGHT vendicate you, LOOK ELSEWHERE. You were WRONG, deal with it and move on. You only make yourself look worse, although I don't know how much worse you can look.

Isn't your pity party thread needing a bump?

[2SSRS@Gen5diy]

I now what i am doing, I asked for the same reason you did and if its something good for you then its good for all of use, And that is the point is it not, Or do you think that only some of us need this info?, I don't and was told that The A/R will be given and was not.

So as soon as i asked for it you and all the rest of the fanboy's started acting like boys, If you cant stand the heat get out of the kitchen.

[ShnOmac]

Seriously the pissing match is getting old......

[2SSRS@Gen5diy]

I think you are right on the mark.
