That info has already been collected ive been told, so going to call the builder of it and get a copy and also see what he thinks..

Torque compared to other cars make perfect sense your car is laggy compared to like jarons car which makes big torque early your past the big torque area when you hit full boost (same as mine)

I'd love to see the results of that, I'm pretty sure you know I think your inlet manifold is a peice of shit If rigoli can run a 9 on a stock inlet manifold...

find me a fken silicone joiner....

But matt it makes perfect sense, because as soon as boost hits around 1.5 bar it swells up 4x the size, that would prevent the pressure created..
simple...

Have you tried getting a 3" piece of hose to go over the 3&1/8"...I know the lightish blue stuff go gear sells will stretch, but the thermal flex stuff is a lot harded to stretch....might be just what you need tho to stop it swelling tho.

3" - 3&1/8" is a pretty wierd size....I`ve never seen one in any catalogs, its usually 1/4" steps.

Whens it going to the drags ?

Plenty of rexes running 1.8 bar that don't swell the joiners up like that, must be a decent restriction somewhere after that joiner to be causing that to blow up..

you'll be flowing a lot more air at 1.8 bar obviously, which imo points again to a restriction somewhere.

Not only is it swelling, it's actually stretching and pushing the inlet pipe back. I'd definitely be investigating the restriction, rather than trying to fix the swell. It's swelling and stretching for a reason!

Test your stock manifold Tino.

i would be running 4inch fmic piping.... thats bound to fix it

^^^ What he said.

I'd be looking at whats in between that joiner and the cylinder heads, to find your flow restriction..
