Size Does Matter

cool cool. very interesting results but.

[cameron]

The wiggle up top is because of the 4wd.

Wow thats quiet an increase....

Your right about the cams but you have to get the correctly match turbo for the engine's intensions.

I've only ever seen thoes sorts of gains with n2o in place.

Ok so I take it you won't tell us the specifics... but how about something general -

1) These types of gains, or even something "similarly comparable", are they "available" across the board provided you have some sort of hardware under the bonnet?

2) What should people take into consideration when making their "cam selection"?

3) What made you guys change from the old ones?

bout time paul

i dont want to speculate on the specs, so cant u just put us out of our miserie please (or just the big 2, engine capacity and turbo selection, or r u still running what u had planeed originally?)

[T04GTR]

quite clearly youve got a very good bang for buck upgade lol

[180bfj20det]

Man are you sure they just didnt have cam timing wrong with the first setup?

25psi for that much power "drool"....exotic fuel and nice turbo setup.

What times are you looking for?

Nice work...

[T04GTR]

well from thw graph it looks like my badly tuned t04z just DOUBLE THE POWER

[T04GTR]

*plans on checking in later to se cam specs. hmm 2 up and 1 in duration.......

got a pretty go0d idea. il just keep that to my self. hehehehhe.

[Gav]

We have have seen a silimar phenomena when fitting a larger inlet cam.

By going from a 264 to a 272 duration on the inlet and spending more time on the dyno adjusting cam timing, we were able to achieve earlier boost response, significantly better top end AND at a lower boost pressure. Both cams are now 272 STEP 2 HKS items.

Other specs as per the RB26 Turbo Upgrade Sticky

another related weird power issue that i witnessed was with mark jacobson's car at autosalon, on an early run he wasnt making the power he thought the car had, so he played with the cam timing abit and on the next run picked up 200hp

Paul, Stace says hi to you and Sarah

[T04GTR]

i dont want to pull the head off so can jam bigger sticks in there

[shanef]

yes you do, remember u were just itching to get it off

i guess we have to wait til tomorrow for paul to post in here. oh how the wait is going to kill me

P.S i'll have a guess and say there in the vacinity of 10.xx lift and 27x duration, am i right?

[Adriano]

Man thats so much difference it looks like it was done in 2 different gears.

Definately no funny business like that going on...ill make that quite clear.

But yes the result shocked even the builder and tuner.

[r33_racer]

yes indeed...i havent picked my jaw up off the floor yet either lol

Bigger than that

[shanef]

hmm so 11.XX and 28X ? whats the bloody thing like at idle? (dont suppose u just happen to have a vid of it?)

and is it a JUN bottom end?

who said it was my engine...or car ?

while some would have been happy with the original result (BTW this is pump fuel and no NOS) , the end result was achieved due to the effort by the boys at Croydon's. Truely world class...
