*POWER RESULT*stainless steel muffler (aftermarket)


Hi Guys,

I can now announce and confirm that Paul (kenzotrail) a member of our forum who has accepted the offer to do the 1st twins kit template (without a towbar) has successfully completed the mod.

In addition to the great looks of the twins, Paul had his exy dynoed before and after the mod and I'm happy to confirm that all twin owners can expect an approx. 10KW power increase at the wheels.. WOW! emoticon

I can now explain where the extra power that I can feel at higher RPMs is coming from, as I initially thought it had something to do with me cleaning the K&N filter.

Here some pics of Paul's exy having the ready-made kit installed. (notice the extra 2 flanges with bolts) This ready made kit will consist of 3 sections.

It is good to see that they have used silver paint for the joints this time emoticon

Here are a couple of shots of the beast on the hoist and the dyno.

Finally, here is proof of the power increase emoticon

The 2nd kit for those of you with a towbar will also be made available soon, as Dave (dviv) has take-up that offer. Thanks Dave!

Hi-Tech Mufflers are now in a position to take orders from interstate and overseas for the 1st kit.

Please refer to the Discount Offer for details.

The price of the ready-made kit mailed to customers will be less than the one fitted here in Sydney.

Re: stainless steel muffler (aftermarket)


Hey Jalal,

A little bit off-topic, but this is related to the dyno runs shown in this thread...


Who can I contact to get more info on the dyno runs? (I'm assuming C&V Performance, as indicated on the printouts?)

I'd like to know if they were done in 2WD mode or 4WD mode...

In my opinion, for an engine that is claimed to be 132kW @ flywheel (unmodified), the 86kW seems quite low for an "at the wheels" figure. I am saying this in reference to an unmodified Pulsar SSS (SR20DE engine) which has 105kW @ flywheel, and gets around 80kW @ wheels. My modified SSS got 109kW @ wheels (on a different dyno), which I thought roughly equates to about 135kW @ flywheel. (FYI, my SSS got about 93kW on C&V's dyno).

I should point out that each dyno machine is going to be different to another one, but there are also different "modes" that can be used for the dyno run - I wonder if they used the "shoot-out" mode for the above X-Trail runs...

Hi Rich,

Yep, contact C&V Performance direct or speak to Lambros at Hi-Tech Mufflers who knows them.

the 86KW is at the wheels figure.

At the flywheel this figure would translate to around 152KW as conffirmed by Hi-Tech.

That extra 9.2-10KW at the wheels is VERY noticeable by me when I travel on the highway and take-off at the lights.

Please note also that C&V measure a 4WD differently than a sedan/hatch. That is why it may seem that figures you got for the Pulsar are higher, but they can't be compared to 4WD readings.

Your best bet is to have your exy dynoed by them, so we know what a stock exy reading is.

I'm note sure about 2WD or 4WD modes, but I suspect it was dynoed in 4WD mode (Paul can confirm this)

Hey all,

This Dyno was done in Auto mode. Reason being most people would be using this day to day. With the up and down at the high end I believe this is because It started switching to 4wd. Either way you can see that the exhaust was worth every peny!

Paul.

Just a quickie.

Where did you get the dyno done and what price. Do you need to alter the fuel/air mix to get these results ??

I have got my exee booked in for the twin job at Hi-Tech (Kelso) in the new year.

Paul.



If it started to switch to 4WD that would be because the front wheels were starting to lose grip on the dyno rollers. I imagine they had the (back of the) car strapped down to prevent it driving away when the rear wheels became "live" - if not, it would've driven right off the dyno emoticon

I haven't had a good look at the dyno sheets yet, but I definitely do not doubt for a moment the value of the exhaust upgrade. 10kW is pretty good for just an exhaust. Whoever does extractors as well would be pleasantly surprised...

Jalal, as for the "C&V measure a 4WD differently than a sedan/hatch" quote - I find that hard to believe as an engine is an engine, no matter what body type it's bolted to... Unless you're getting at the point where Paul mentioned about it being dyno'd in "auto"...

I'm no expert at Dyno tests myself and only repeating what I have been told by Hi-Tech Mufflers who clearly stated that the dyno settings are different between a 4WD and a sedan/hatch. If that means that the 4WD might be and should be tested in Auto mode, then it might explain the difference in the results between the Pulsar and the exy. Obviously it has nothing to do with the body and shape of the car being tested emoticon

Re: stainless steel muffler (aftermarket)


Don't forget that the X-Trail has a sophisticated electronically controlled 4WD system so there are bound to be more losses than through a direct drive 2WD car.

Out of interest I will see if I can find out what the difference between at the flywheel and at the road wheels of a Skyline is, as the suspension system is very similar.
