You can smoke even with an 8mm pump with too long duration. If only Giles would tell how much cc his pumps gives as that would give a quantitative number of how super those pumps are or not. 120cc 11mm pump dynoed 204-205whp

2.5" intercooler piping is a bit big. 2" will help with smoke, as the 2.5" would be a race or all high rpm only application. That may help with the smoke early. Especially if you have a bigger than needed IC.

I say something is off as I have a Giles 10mm maxed out and now that I eliminated the boost leak I have 0 smoke and EGT around 700f peak...I did a lot of porting and head work though. I don't think it would make that much difference.

Like Alcaid says... The challenge isn't so much total fuel quantity as it is timing. If you're running a 10mm pump and smaller injectors you can make lots of smoke and high EGTs without making all that much power. It's about getting it in there fast enough that it gets burned while the piston is in the right place.

smaller injectors in an IDI?

On my setup it has an aaz camplate with the 10mm head.

Ah crap. Wasn't paying attention to which forum I was in. A 10mm pump would actually be pretty hot on an IDI.

Are you giving up? In my coutry 1.6 D engines are so cheap I don't really care if my blows up.
As long the turbo survives...
Please report what happened.

I'd be very interested to see what your exhaust manifold pressure is like at 40 PSI though, you're in the danger zone for the exhaust valves not closing.

Says who? What do you think is going to hold the valves open? 40psi on the intake side? Not likely.

40 on the intake side could easily be 60+ exhaust manifold pressure...

I disintegrated a rod bearing completely destroyed it to nothing but  pieces of metal in my oil pan. Bottom end is toast. And I can't afford another rebuild after 1250kms

To much boost I'd say and the bottom end just couldn't handle it. Very sad but nothing I can do now

Hey guys just wanted to put a little update about this. I put an engine in it. Did a little stuff and now I make just about 50psi yes that's right 50psi!!! Hauls pretty good. Egts get high but I just hold it and it keeps pulling
