Angry No boost - learnt my lesson

Well, I have been taking my time rebuilding the engine from ground up & going EFI. Finally gotten everything together and was able to drive the car. Then, I noticed I have no boost. Zero!

After the usual procedure of suspecting my own wiring, ECU, ... I finally taken my "new from another Pelican" intercooler to the radiator shop for a pressure test. And it is leaking in 6 spots !!!

Yes, its been sitting in a box when I bought this supposedly new, never installed intercooler from another Pelican. Yes, I should have pressure tested it the 1st day I got it. But, its supposed to be new (& it did look shinny new).

Oh well, guess I have just learnt a lesson to not trust anybody or anything used/private sale/... And a good, new looking intercooler doesn't mean its good

Sigh...

And sorry for wasting the bandwidth but just wanted to rant.

I would think that even a leaking intercooler would still make some boost. I had a serious air leak (Blown intecooler to pipe seal) and the car still made boost. As it was CIS the mixture was off due to the escaping air.

Well - the shop that did the test said it wouldn't even hold 3-4psi. I confirmed by ducting my turbo directly to the TB with my make-do pipes. I get instant boost to ~.4 bar then my home-made pipe separated. So I know the rest are good.

Its one from GSF - I have received quite a few parts from them and they are all good so I kinda think its not manufacturer defect. Though I didn't pursue that with them due to time constraint - I want and need an intercooler fast so I cant afford the back-&-forth shipping time
