[djbrowney]

whats the spec of the engine ???

[novadose2009]

no its custom made 1 he is currently making

You can go too big & the engine can only consume 'so much' air, so keeping the TB sensible should maintain driveability & engine characteristics especially on small throttle openings.

[novadose2009]

engine spec is

low comp pistons
H rods
ARP bolts
steel head gasket
highlift cams
evo8 turbo
470cc injectors
custom inlet
3 inch straight through exhaust

[djbrowney]

just buy a cav v6 throttle body will be perfect !

what managment is he using ?

[Stuart]

any elaboration on the custom inlet? lol

as craig said though, you can go too big so the engine is consuming max airflow at say 75% throttle opening etc which makes for a dire dire dire drive, trust me!

[novadose2009]

6 inch deep
4 inch wide
20 inch long approx as not built yet

what managment ???

well he can only run vauxhall one then really beacuse it wont pick up the tps, its a lot of ****ing about to get it set up on another. either the cav v6 4 bolt or vectra v6 3 bolt both more than capable they will will do 550bhp all day long !!!
