Your B16A dyno results?

[JasonGilholme]

i think your on the right track about different dynos.

and your mrs isn't helping either lol. (thats why hannah never drivers my car lol)

New engine ftw!!!

[redinteg]

ok yesterday i went to a dyno comp at mazfix i ended up quite confused now i know many might think my previous pull of 108.9kw untuned is a bit high.

Many may think this proves it but yesterday my car only pulled 124.2hp or 92kw that is a 17kw drop.

The only difference i made was to take the filter off my injen intake and mount a bellmouth in my bumper

I'm basically putting this down to Different dyno, shouldn't have taken the dyno proven filter off, the car now has 220,000kms and the last and worste my mrs thrashes it when cold.

looks like its time for a new engine or a rebuild but in the mean time can anyone confirm my reason for the loss or add anything interesting

Different dyno, weather, changing the filter and your car may have been dynoed in say 3rd for your 108kw run and 4th in your latest.

could it have anything to do with that they didn't pump the tyres to 40psi like last time.

lol i just went and checked because i didn't see them pump any tyres all day and even thoe the dyno printout said that my tyres had 40psi they are at 30 psi today

[turtleEK1]

I'd defenently put it down to different dynos.

Dynos are not all universal as far as power output goes. They're more of a tool for tuning.

Could also be different atmos temps, pressure, humidity etc. Could be other little variables that could add to the different figure?

Have you noticed any loss of power over time? Maintain the motor frequently?

[ek4-guy]

both runs where in 3rd gear

i have noticed its down on power of late but dint think it was that much

as for maintaining it ive been pretty bad of late because i know a new configeration will be comming soon


just check one left front was 30psi and right is at 26psi i dont think this would have effected anything to much but speaks loads about the dyno guys

yeah but it maybe correct.... does it feel like it's lost power... on an NA you will definately feel 17wkw loss/gain

[ek4-guy]

it does feel like it lost but not 17kw that puts it back to nearly stock, i think in my haste to get a lil extra by taking the filter off i crueled myself


Archie from Mazfix was saying sometimes its better not to take the filter off and when i told him it was a injen cai his response "oh see there you go"

[JasonGilholme]

the dyno runs should have been done in 4th gear.

If the run was done in 3rd there would have needed to be a conversion done on your result to get it to read correctly. If the converson was incorrect then the reading would be off.

[ek4-guy]

it's got on the sheet gear was 3rd i think all the runs were in 3rd

what gear did Mercury run them in?

lol ive lost the Mercury 108.9kw print out just like the power

[SLOWEGG]

Mercury Dyno Day, they used 4th gear.

[JasonGilholme]

it was done in 4th.

Don't know why these other guys did it in 3rd. Although 3rd would have returned a higher reading which is what makes me think theres a mistake in their calculations or their dyno is rooted.

[Limbo]

most likely the Mercury was done in 4th gear that might explain you 17kw loss.

And yes they should be doing it in 4th gear as that is what the general standard is.

In relation to low tyre pressure, as the car gets hotter the tyre pressure will go up and give better readings.
Was it only 1 run?
