The thread started a while ago and ive been keeping a keen eye on it Basically people are aiming for 230ish rwhp from bolt on mods.

The last post is a guy who has actually got some dyno results (rest of the thread seems a little worthless without) and some other dyno's look like they will be coming up fairly soon.

I posted a few disbelieving comments, as some of them seemed to be in fairy land! But - the VersionJDM chappie seems to have made 24bhp from a few simple mods.

Puzzled how the Spoon pipe seems to have made so much on its own?!

That gain from just a spoon exhaust seems really over the top! The gains after the exhaust seems right but that much from an exhaust?!

 

if dynapacks were are so good.. why do people spend $$$$ on installing much bigger dynos.. my local tuner here has a autodyn (Superflow) which is quite an involved installation.

however when I was in Japan.. both amuse and J's were using dynapacks?

 

I'm not a fan of them, although have limited experience. The best ones around are Dyno Dynamics, they seem to be very accurate.

To be fair though, the guy above did get a stock dyno power figure at what you would expect. A lot of it depends on the RR operator too, but maybe they start to over-read in an exponential fashion!

Thought there would be lots of interest in this

Some more info trickling through...

Interesting...

Good find Mark!

 

230 @ the wheels isn't really that hard. But it's not something you're going to get without some small scale non 'bolt on' work. I mean UK horses too - where you're starting from 190 or so, not the Shetland ponies that appear on so many dyno sheets. You won't see many cars like that at all though... people simply won't pay the sums needed in one shot to do a proper job. I'm not saying it's rediculously expensive either - any people spend much more on modding for far lower gains. But they do it peicemeal... and balk when quoted for a proper job in one to make proper gains. People just prefer slapping parts on one at a time, and hoping the resulting system will be in some way optimal.

Dynopacks are fine for power figures, if they're setup properly. All too often the operators don't know how to set them properly, end up getting the corrections wrong and the figures end up usless. Dynopack's real limitations are to do with the control of the load - they're not much use for mapping aside from WOT.

Dyno Dynmanics stuff is okay, but hardly the best. Then again, the best dyno's, along with the sensor rigs that make then the best, tend to be only in race shops - most of which have zero interest in tuning cars for kids.
