Fast Intentions exhaust is here!

I have had Berk HFC's on for about 2000 miles no codes thrown

FuszNissan · 07-22-2009, 12:26 PM

I guess if your car goes to the track every weekend, maybe something to look into, but if you like me my car sees 6,000 miles a year, then I wouldn't worry about it.

guys I will shead some light on the CEL issue. I have had both Berk and FI HFC's on my G37. The Berk threw a CEL from day one. But others have not throwen them. I have had my FI HFC's on for 10000+km now and just got the CEL. but I am running with out the non-fouler. I called tony and he is shipping me out a set to look after me. But he is busy with all you dudes ordering for the 370Z. so slow it down and let him ship me my non-foulers. lol

This might be a valid concern, but it can be remedied pretty easily by making a cover yourself for the rear center underside. I'm kinda waiting to see what I end up doing for cooling the rear diff first, and then I'll look at any airflow issue there after that.

As said above, I don't think anyone's been getting CELs on the 370 with HFCs, at least not the Berk ones. And you need to stop ordering G37 parts so I can get my exhaust faster

Ya the set up almost looks as good as the set up on me G37S

Caravanshaka · 07-23-2009, 12:05 PM

You are both using highly efficient mandrel bent piping, with straight through mufflers. A couple extra bends is not going to make a huge difference on 7psi of boost. I do agree that the straighter design will likely be a little higher, I just don't see it being more than a few horsepower. If you can prove me wrong then by all means show me the numbers comparison when you have your boosted Z and I'll be more than happy to tell you I was wrong

DDM said his intentions were to dyno his car in its current form and use that as a baseline, then add the exhaust and dyno again for the gains. He was never trying to mis-lead anyone.

Why did they not dyno it with the stock cats? Because DDM has had the cats on his car for months now and didn't want to have to pull them off and reinstall everything stock just to get a dyno number. Using a baseline with his current and showing the increase is sufficient to show that the exhaust makes similar power to other competitors. With his only access to a dyno being another shop that is hard to make appointments, I don't see a problem with this.

I am pointing out that compared to your high flow cat and cat back combo dyno pull compared to your baseline, you made less overall power than the Berk combo did when looking at their individual gains. Yes, the dyno situations were not the same, which may mean we are retarded for arguing about it over the internet, but it's going to be VERY difficult for either of us to prove anything unless we got the same car, dyno'd it completely stock, then dropped the stock exhaust and dyno'd it with the FI cats and CBE, then dropped that and dynod it with the Berk cats and CBE.

I doubt we are going to get the chance to do that, so for now we can continue to try and make our points

I don't think DDM was trying to mis lead anyone. I don't know them but I have heard nothing but good things about them. However, IMHO when you are trying to launch a product, you have to dyno the car in its true form (Stock) and anticipate that everyone is stock when they buy your product. This is the only way to have true real gains. What if someone called and wanted to buy their cat back but already had someone else's cats. You cannot give them a definitive answer on gains because you have nothing to compare it to. For them making more power, show me a dyno graph where they made more than 305 with their high flow cats and cat back. All I see is a 296 number. So you cannot say that their combo makes more power.

As far as the boosted aspect, it seems I am getting nowhere with you on that one so I will concede for now.

Caravanshaka · 07-23-2009, 12:27 PM

I agree with that. It's just not easy for a daily driver to put all his stock stuff back on to do a dyno run. I also don't see someone with berk HFC's already getting a 20 whp gain by adding an FI exhaust. You are talking a 35+hp gain then, and if that's the case then sign me up for that combo

as far as more power goes, dyno calibration and conditions can play a pretty big factor there. Again, I agree the number from Berk being so far apart isn't as credible as yours, but it was the same car at the same dyno shop so I can't discredit their effort in getting accurate numbers. If you and berk both send me catback and HFC's I'd be glad to hit the dyno for an all-day session comparing the 2 and then I'd send em back, but I don't think you guys will be up for that, lol. Plus you probably have someone much more local that could help out if you wanted to do a head-to-head.

With the forced induction, I have a point of reference for that number based on personal experience between a crush-bent muffler shop job in 2 1/4" piping compared to a 3" Blitz Nur spec turbo exhaust which was only a 6 whp gain on 12psi of boost in an SR20det. If the boost on this 6-cylinder responds that much differently to it's exhaust, I'd be glad to say I am wrong...I'm just going off of my personal experience right now.

Once the exhaust comes in I will dyno my vehilce as well and see what we get. It will be with the Gen 3 Intake, Berk HFC, and F.I exhaust. I hope to make 30whp with all of that.

that should be no problem at all =) stillen claims 54whp or something like that with that 3-combo if you used all of their parts.

You will!

wstar · 07-23-2009, 12:36 PM

Re: the Berk and FI results, it's all apples and oranges anyways due to different dynos and different environmental conditions really, not to mention the whole HFC vs Stock issue. They're both performing pretty well though.
