I think you're just making a mountain out of a molehill.. I've noticed this trend with you ever since you discovered that there isn't a close tuner to you. You went with Greddy, good for you. Just drop it and enjoy your kit while your motor lasts.

 

Very mature dude.

I hope for your sake you have a qualified tuner in your area if not your are going to spend $10K and end up with less hp than you have now.

Enjoy your kit and keep sucking Peter's nutz.......

 

Peter, can you clarify the out of the box, no tuning, APS TT whp that we can expect? I keep reading all these different numbers. What psi is it set at out of the box? If I have nothing done at all, and throw this kit on, tell me what I could expect on a dynojet. Somebody said 350whp, somebody else said 400whp. That's a big difference. Thanks Peter.

 

Great, you called me immature, and then.. ended it all with

"Enjoy your kit and keep sucking Peter's nutz......."

bravo... enjoy your cheap kit while your seals blow out of your turbos and not having a front impact brace.

 

I think there are 3 confusing issues that impact on power readings, one is the fuel octane rating, another is the performance of the exhaust system installed with the APS TT system, the other what type of dyno is being utilised for the dyno test.

At APS we always utilise our own APS TD exhaust system on every APS twin turbo system installation (this exhaust system has zero exhaust back pressure at 380 WHP) and I'd expect to see approx 380 to 390 WHP on a dead stock VQ engine - this power figure is normally a little higher on a dyno jet dyno, around 20 to 30 WHP higher.

With what brand of exhaust system? The amount of exhaust back pressure in the exhaust will have some impact on the turbo pressure in the inlet manifold.

With an APS TD exhaust system the boost pressure is approx 8.5 PSI out of the box though this will alter marginally depending on the exhaust system utilised.

With an APS TD exhaust system and on 93 octane fuel I would expect approx 380 to 400 WHP depending on the brand and type of dynamometer used for the testing, I know this is somewhat confusing though different brands of dynos read very differently.

Thanks

Peter

 

Your right. I appologize. I was just putting the facts on table so those thinking about this kit know them. Judging by all the other posts on this thread people don't really know their options when it comes to tuning this kit. That does not give you right to flame me and hope that my motor blows. This forum is here so people can get information and give their opinons. I gave mine and it seems like you didn't like it.

 

Here is quote from a member on another board. This guy has an APS TT on a 350z and dynoed on a dynojet, which according to Peter usually reads 20-30whp higher.

Here is another post from from captj3. I asked him what kind of dyno he dynoed on.

Without the test pipes he gained 103whp with the out of the box tune.

 

I certainly hope your motor does not blow, by all means. Good luck with your buildup.

 

damn, isn't 10.1 rich from 3k up? I can understand it being on the safe side but that seems really rich

 

That's an interesting viewpoint, a dead stock 350Z mearsures approx 210 WHP on our dyno dynamics dyno so if he's now achieved 360 WHP that's a WHP gain of approx 150 WHP over a dead stock VQ engine.

I normally dyno and measure the APS twin turbo system and TD exhaust system installed at approx 380 WHP on average (stock WHP is normally around 210 WHP) - that's a 170 WHP gain from dead stock power to APS twin turbo power.

That said you will always see a variation in power from state to state because of different environmental conditions, fuel octane quality, and the engine itself.

You only need to have slighty lower or higher fuel pressure or boost pressure from engine to engine and this can effect WHP very easily by up to 30 WHP.

Thanks

Peter

well he gained 103whp when he added the APS TT. Unfortunatley he did not post his bone stock numbers. He posted his numbers with hf cats and exhaust and then hf cats, exhaust, and APS TT. His highest dyno with hf cats and exhaust was 257. I highly doubt that he gain 40rwhp with an exhaust and hf cats. Let's say he gained 30rwhp is extremely high for those two mods, then he would have gained 133rwhp from stock.

It just seems that out of the box tune numbers are a little inflated IMO. With that said I HAVE NOT DOUBT THE APS TT CAN ACHIEVE MUCH HIGHER NUMBERS WITH A CUSTOM TUNE OTHER THAN THE BOX TUNE.

 

According to this guy he had the first APS TT in the US installed on his car. Look at his out of the box tune numbers. He had to have it retuned to get to 400whp.

 

Well I guess that GRD can supply a map via mail tune for a built engine but it looks like they don't recommend it. This a response from GRD after I asked them if they can mail tune the unichip for a vq built with low compression and forged internals.

Jorge we can send you a map that will be close but it is always safer and beneficient to get it tuned.
thanks

I believe that answer is absolutely correct - a generic tuning map will be close though not perfect, a custom dyno tuned engine will always provide the most powerful and safest tuning strategy for a high powered VQ engine.

So why did you previously post this.

If it is not safe to mail tune then what good does it do for people that don't have access to get the custom tune? Aren't you the one that talks up and down of how important a good tune on a load based dyno is? Close only matter with horse shoes and granades not with a $10K motor.

Thanks
