Nistune Done! Gotta Love Hypergear Turbos!

also make sure that the wastegate enough pre-load. this can also be a source of sluggish response and it used to pop up from time to time with GCG turbos.

the EBC will probably sort out most of your issues but just another thing to look at if it isn't sorted out.

What do you guys think of the boost curve? Trent recommends the gizmo ebc as a good one for the price($300), would it help keep the boost up in the top end or is the turbo starting to run out off puff?

cheers

got a photo bigger than that?

woops!

A good ebc will get the most out of your turbo by keeping your wastegate shut better than a bleed type boost controller. I don't know if your turbo is running out of puff - what's it supposed to be rated at? Should think you would be able to keep it nearer 16psi a bit longer with an ebc.

I think stao at hypergear mentioned it should be good for up to 270rwkw though i think around 250rwkw in an auto would be realistic. Yeah i think an ebc would be the go...

Yeah even with the stock boost control though it's making somewhere around 14PSI up high. But I guess it could probably do more than that, and down low/midrange it really isn't great.

I've been looking at whether or not I can squeeze a 12"-long core from frozenboost.com into the stock SMIC location. I'm not sure it'll fit though, since the stock SMIC has one front-facing pipe and the frozenboost core has both pipes exiting vertically... I'm not sure there's going to be enough space to make the turn.

Just gotta get around to pulling the whole front bar off to take a look at the SMIC in-situ... too much like hard work atm.

Dave you don't have to touch the front bar - just remove the wheel and undo a few small bolts to peel back the front of the inner guard and all is revealed (maybe a couple underneath as well but just a few minutes work). I swapped out my smic that way.

A decent EBC should be able to turn that bumpy boost curve into any shape you want - and providing you're not just generating pressurised hot air with an ever decreasing CFM rate, flatten out the top end, or even increase the boost there.
