So if a HT can get 18kw + 3kw = 21kw + 11kw = Possible ~32rwkw
If you got both their cat back exhaust and the Unichip.

Peter,
From earlier threads you mentioned that the UNICHIP will not be used on the APS TT kit so if I buy the UNICHIP will there be any refund/exchange if you buy the APS TT kit?
Will the UNICHIP be spliced or have a Y plug ?
Is the UNICHIP the same as all other UNICHIP modules? ie: If I have one from my WRX days then I could use that with a base map supplied by APS?
Cheers,
Michael

I find it incredible that a cat back exhaust system can produce 18 kW's of additional power over the stock exhaust system (if that's true it would be the biggest power gain from a N/A engine I have ever heard of from a cat back exhaust in my life time) remember the cats or stock exhaust manifolds have not been replaced with high flow cats or headers.
I can't believe that a stock Z car made 175 RWkW's with only a cat back system, in my view something fishy is going on here (maybe the fuel pumps in Sydney have 100 RON fuel).

Every H/T exhaust fitted has gained at least 15 RWkW.
Thats a fact.
I gained 6RWkW from adding cats to a stock exhaust.
APS setup looks like its made really well, I just wonder if it will sound as good as a HiTech.
Either way its promising

Perhaps there is something they're not telling us about the fuel in Newcastle too??

If there are any Melbourne forum members who have this H/T cat back exhaust fitted to a Z car please send me a PM if you would like a free dyno test on your car.
Yeah maybe this issue is only relevant to NSW.

Peter, dont compare the numbers between different dynos and different cars. Compare results from the same dyno and the same car. You said yourself you dont have a dyno of the car you used with a stock exhaust on.
https://my350z.com/forum/showthread....threadid=60106
Here are all the posted dyno results from some of the people in this forum. But the ones in shootout mode will return slightly higher overall results. There were some issues with the Croydon dyno and Harrys was in 4th instead of 5th, but if you look at them all, you can at least get 15rwkw.
I dont think mentioning REAL/HONEST was necessary. Look at the dyno charts there are several there from different locations on different dynos. You havnt even showed one dyno chart.

The dyno being link to above is my dyno from Croydon! You all should know that it was done in 5th gear and that it was the SAME car on the SAME dyno. (ie it was done properly)
If you remember even I thought Jim at Croydon had messed it up somehow but i took it back and it still gives out 170rwkw. I dynod twice at 149rwkw and 151rwkw when stock.
Peter, you might want to chat with Jim if you think he's telling tall tales with his dyno! God knows we thought so at first too.

APS measured the Z car in shoot 6 software and the APS dynamometer is calibrated monthly. None of this makes any sense to me it's like saying 2+2=6, I do not believe that a cat back exhaust only will produce 15 kW's of additional power on the Z car, though I will do all in my power to clarify this issue.

Peter, if you want me to put the car on the dyno again at Croydon i'd be happy to do it. God knows I'm itching to put on a UNICHIP like everyone else... if not more so.
I've had this car since Feb 03. There was nothing out there for the Zed in those days.
Anyway... the offer stands! In fact i'd be happy to put on the Unichip if it proves to have power on the Dyno here at Croydon. PM me if you need another car to test on.

We await your findings. Maybe next time find out a baseline before you comment on other peoples honesty etc.

I have a real good idea what's going on here though I will keep to to myself until I have more time to investigate. By the way if you don't hold/tie the car down well on the dyno you can easily get a false power reading (high power measurement) and this false power measurement can be up to 15kW's at the tyres. As a matter of interest what do you guys think the stock power is for a Z car on a DD dynamometer.

Obviously the people tuning a 350z TT would have baselines but you said yourself you didnt have a baseline of the car you tested with the HT exhaust? That is what I was refering to.
