Size Does Matter

[Swiper the Fox]

This goes against convential thinking...but...

an incorrectly matched cam and turbo package can make or break a build.

this was a laggy set-up till slightly bigger camshafts were installed

around 300 more KW at 150kph...wow

[r33_racer]

what tha?

you said 300 more rwkws over what it had before the cams? Am i understanding this correctly?

If so...goddamn!

[paulr33]

180rwkw/4wkw

before 5535rpm

after 4392rpm

gtr? gtst? why shoot8 ?

well yeah previously at 150km/h (5357rpm) it was making 150rwkw

now its making at 150km/h (5357rpm) its making 450rwkw

Thats AWKW this a 4 wheel dyno...but yes r33 racer you are understanding correctly. (you can pick your jaw up off the floor now...lol)

Paul its a single retarder DD dyno...it ramps and reads more accurate in shoot8 with big hp cars. we have proven its accuracy to within 1kw at Autosalon (dynolog) on consectutive days.

good stuff, looks good, say hi to sad for us

God dam.

Do you have a link to your engine mods and fuel you run?

What on earth is that cellulite (multiple disgusting dips) on your new power curve?

Paul, Stace says hi to you and Sarah

boost graph anyone ??

[paulr33]

will do, yeah crank it up

[Swiper the Fox]

will do, yeah crank it up

fark nice result! what size cams you using? also whats with the wiggle up at the top end? boost controller not coping?

[StockyMcStock]

that could also be PARTLY due to the RPM at which the run was begun. if you have the car idling in 4th on the dyno and put your foot down to log the run, it will reach full boost sooner than if you start at 3000rpm and put your foot down.

just a thought - the first run starts at 90km/h and the 2nd starts at 60km/h or so.

the cams certainly did make a large difference though, i'm not detracting from the gains which you have found. the difference is quite marked. it is one of those "all or nothing" power curves in which camshaft selection is critical as well.

top stuff.

I want to know :sorcerer:

[StockyMcStock]

could be wheelspin mate.

[r33_racer]

with that much power....what else could it be?

[Swiper the Fox]

I want to know :sorcerer:

this is a thread merely dismissing the myth that larger cams mean laggier engines that make power later in the rev range. Engine details are irrelavant at this stage.

hmmm, interested in these mystery cams is me ehehe.

[T04GTR]

i spose thats abit rude lol

[Swiper the Fox]

hmmm, interested in these mystery cams is me ehehe.

Dave all i can say is one step larger in lift and one step larger in duration (inlet cam was two steps in duration) as they were different but now equal. Cams are off the shelf items of Japanese origin.

shitload more torque.
