Amazing the difference an auto makes, different turbo, bigger injectors, 3psi more boost

950nm torque

blue line old tune manual

red line new tune auto

average 344hp from 90 to 180kph in top gear

368rwhp 700ft lbs

HOLY SHIT

 

JAW DROPS WELL DONE ROD thats pretty damm cool

onlyyyyy bad thing about dynos is when if you have a different diff or tyres or gearbox can changee the hp a fair bit

That is because the power delivery is different.

 

With dyno's it is the rate that you can turn the tyres, if you have a close ratio box and diff with short tyres then you are able to spin the engine up faster.

 

The tyres with my dyno run were actually taller then the standard 14" tyres so I lost a fraction of power.

 

A dyno isn't exactly the best at showing power though as it is a tuning instrument, there are so many different factors in them that you are better off doing a few runs at the drags and using 1/4 mile converter to get the HP.

 

The dyno that I ran my car on was also supposed to of had read low, I am not too fussed on this as I will take 90hp as a good figure for a FWD auto that has 300'xxxk's.

yeh to many different factors that come into it, first time we went we had 57hp, second time 52.4 but that was with a 3.9 not 4.1 like runnign before and he said diffs are atleast 10hp diff between rations

Also on a different day.

Now there's a quote i wish i could frame.

 

You can claim all the hp in the world, but one full power run at the drags will tell the true story every time.

Done.

 

thankyou sir, now which wall to hang it on :hmm:

Its all about dyno ramp rate, you want it set so the car is accelerating like it does on the road,if it accelerates

faster then it throws up a unaccurate torque measurement which then throws up a different power figure. So if you change

your diff gears or box you have to dyno on a different ramp rate and load it up more. Thats where the shootout mode has its flaws as it locks in a single ramp rate for some motors. Have played with it a bit on mates dyno and you can see how some workshops get there "higher" figures.Thats how DD dynoes work.

 

The Blacktop dyno is still the best!

cheers
