kev what would spool be like on a CDB forged 2.1 with either a gt30 or gt33(billet)

standard heads at the moment

im going down this route v soon and dont really want to sacrifice spool ( i currently have a 321t on there)

cheers

I have aftermarket headers, Kakumei, i believe. OEM might be better, but here is dyno chart about them with VF36, if you are interested to look.
(AVC-R setting is not very good))
5th gear, weather: maybe 5 degrees celsius.

Sorry about offtopic.

Edit. 2.0 engine, AVCS stock setting.

Hi,

we dropped the GT33 billet as it never worked properly on a scoob. :cry:

Gt 30 Billet will work very well on a 2.1, that's what we run on our drag car. :D

it is on E85 though. :thumb:

^^^^Holy bat crap batman^^^

The 30 billet works very well on 2.1, 2.3 etc :)

Thats an impressive figure I was hoping for the right side of 500 with a billet GT30 on my 2.1 v power +30% methanol. Should manage that i would think :)

2.5 forged with a SC46 billet twin-scoll. We got a run on API`s rollers this afternoon.

Sorry its taken so long:rolleyes:

What were the heads and cams?

Cliff,
What's the fuel mix?

STI 8 heads and cams
V-power Shaun. I dont think I will be putting anything else in it..

Cheers Kev what sort of head work was done in the drag car
As I'll be using standar cams for the time being

Steve

:)

Hi,

the heads and cams are spec "C" ones. :thumb:

As I have stated many times before tests show that these are fantastic heads and cams straight out of the box, don't mess with them just fit and map. :D

cheers
Kev

must be amazing on the road, much difference in spool comparing dyno to real world driving?

Are there many results of the GT35R billet on v power?

I know Clive's made 626 but wandering if there are many others?

Mike L did 700bhp on v power

I have some Spec C twin scroll headers for sale in the for sale section, as that seemed a good section to put them in :)

I have a twin scoll sump for sale ;)

stop it :D Need to get it built before I move the goal posts again :p:thumb:

:eek:

Spool on the road is earlier and its prooving to be quite a handful on the road. Goes up hills nicely....:norty:

I had no idea you would be pushing THAT much power Hammer Man! Fair play! Very good result!

Must be handy being so local to APi too :D

How much Simon?!

Dipstick? (Not you; but is one included :D).

Hi,

great result, bet your happy with that. :thumb:

Well done to all involved.

cheers
Kev

That's one helluva linear (smooth) power climb!

Kev,
What lb wheel did you say was in the SC46 TS? ;)

Aren't the figures - BHP - (shall we say) a tad optimistic? :)

Hi,

46 lb Billet wheel, as its more aerodynamic than a standard wheel we know it will shift more air. :thumb:

The figures are higher than I expected but optimistic ? I am ever the optimist. :D

All dynos read differently as you are aware. :norty:

Please take this up with API its not been on my dyno, sure Dave will give you an answer. ;)

cheers
Kev

Never realised just how much the dynos can vary :wonder:

442 bhp @ the wheels on you dyno kev would be just over 550 bhp so why only a small gain to flywheel on api's ?

Cracking result either way,im sure oz is more curious now to see an sc46 ts or the sc42 ts on a 2.0l. :thumb:

How much do a set of used spec c heads go for nowadays

Steve

There like hens teeth pal,the version 10 ones are the shnizel,they have the hottest cams.
