thanks guys, we are hoping for 200 HP at the wheels on 8psi soft tune and 98 pump, ultimately reach 250 HP on E85 with bigger injectors and more boost.
Once we get the engine installed Westi will be fabbing the intercoolers and relevant piping, I'd like to see twin coolers behind the Manxter side pods.
Troys old engine configuration made 248hp atw on 18psi from memory. 2332 with t3/4 turbo, welded volksy heads and unknown cam grind which he got with engine originally from speedway car. Waste gate spring wouldn't hold any more boost and injectors were running 100% duty cycle so needed to be bigger. They were modified rb26 dett skyline injectors. Now with comp eliminators, gt42r and methanol power should be a bit higher lol

Even your memory talks things up!
Better check those numbers before using your memory.
With troy's head flow it would need over 30-intercooled-psi to make 350 at the wheels.
300 is a fair start position if he can keep the flywheel on it.

I said it made 248hp atw not 350 dude. Thats the figures that troy has told me so im guessing he would know lol. could be telling porkies hahaha.As for new combo who knows what it will do? But it definately has to make more than original set up wouldn't you think Dave? Bigger and better heads on methanol with better pipes and manifolds it has to breathe better than what it did have..

thanks mate, always best to double check twice...........not a lot of progress made hopefully will get the copper head gaskets and other goodies from CB before the weekend.
Anyone else have issues with AA cromo flywheel mating to the CB crank?
Those AA flywheels are not very good on the clutch surface. Found it was not very grippy surface and glazed up easily.even when resurfaced. I ended up going back to lightened vw flywheels on anything that made decent power
Cheers Adam
^^ me too, the AA flywheels aren't a patch on old German VW. I know one of Australia's best clutch specialist that has offered to buy any old VW flytwheels to use the clutch surface material in his custom alloy flywheels. It is in his opinion the best material he has ever experienced in his 40+ years of building clutches.
Recently I chucked a new replacement in the bin due to the flywheel mating surface being so poorly finished, it appeared it would have damaged the crank quick smart.
German all the way for me too.

I've run a lightened VW flywheel for years and never ever had a problem. Yanks are very anti lightening flywheels especially when it comes to kombi's. my uncle has lightened a lot of VW flywheels over the years and he loves the quality of the steel they are made of.

will sort out the flywheel issue later, I've just been messing around with setting rocker/valve geometry....I hate doing this,
find full lift 0.383
half it 0.1915
mark half lift
install adjustable pushrod and rockers
set rocker parallel to head, adjuster inline with pushrod, rocker tip 90* to valve stem
I'm close but not perfect, seems rocker stand needs a trim or thinner lash cap
Also got the 0.060" copper head gaskets checked out, now get this rocker geometry right.
