I do have one you could borrow but its only 1bar...
I'll connect it to the inlet manifold then, no chance of that exceeding 12psi
Like I said earlier just buy 1m of 52mm bore silicon hose and fit it in place of the intercooler it'll do the job.
I'll get geeking on the bay.
I once had a 3" crack in my Gt Tuning Bread bin intercooler and the T28 blower still made 21psi (manifold) and like I said on a gt thats through a 25mm venturi!
I've got a compressor if you need to do a pressure test just times tight at the moment.
I've got a tac liteweight at work (field compressor I could use) but how did you go about sealing everything? as surely there will be some leakage through the engine?
