Boosted Performance

The V-bands are a bit of a pain because the flex couplers are stiff when new, and ther is always slight warping no matter what you do when welding. I have tried to tack weld the V-bands in 8 places before doing a solid weld, but they still warp ever so slightly. You will never hear an exhaust leak though..because the warping is very minimal, invisible to the naked eye.

After a few heat cycles the manual calls for re-tightening things, because it takes a bit of time for everything to "seat". I am assuming you have some condensation leaking, and that is normail at first. It will go away once you drive the car and park it again...may only be present on cold starts.

The most important things is that there are no leaks before the turbo, and on the downpipe where it clamps on to the turbine housing. This would mess with spool, and the wideband reading. That is why I made the modification to the down pipe, so there is no chance of it leaking at the turbo.

If there is anything else I can do/help with...I am only an email away

Congratulations on a job well done. You're gonna need to get that refund from GTM to keep you in tires!!!

You are local..I think...and with an A/T. Maybe we need to get together in the spring, to see if there is any way I can make the kit work with the A/T transmission.

Unfortunately, I am not local to you and lives in Petawawa,Ontario (military base). I swapped the 6MT in the Z instead of the 7AT when I did the HR heads swap.

I think I got the exhaust leak sorted with the RTV. Had a nasty rattle that I fixed. Now all that's left is a very subtle rattle that I can barely hear at certain times. Can't replicate it while under the car. Doesn't bother me really but I want to track it down eventually.

Put some miles on the car today. Using dash command to get the boost reading and I don't think it's calculating it accurately. It's saying 12 psi without even hitting full throttle. Either way I'm playing it safe until I get the tune on Friday to see how much boost the car is actually making.

Here's a quick vid of a partial throttle pull. I'll do some proper videos after the tune LOVING the car so far!!!

Are you using a boost controller? You won't hit 12 psi if your only using the wastegate springs.

Just running waste gate spring pressure. Should be the 7.25 psi springs but I'm just being cautious until I get the tune. Not going to kill me to wait until Friday

Yeah, you're good to go. Last I heard the base tune was based off of my car when I had Vince at R/T Tuning tune my car. Always a good idea to have it looked at jut to be sure though.

Yeah I'm sure it's fine but just being safe since the tune is only a few days away. It's really hard not to go full throttle though Can't wait to give it the beans and see what it can really do.

I tried DashCommand to read boost also...got crazy numbers :P Don't know why it isn't accurate. Kit sounds good man. Almost makes me want to get my open-pipe external wastegates plumbed into the exhaust. Mine is so loud I can't hear the turbo lol.

I think it sounds perfect with the recirculating waste gates. Perfect blend of turbo, exhaust, BOV noises

So I've been noodling on this and might know why the boost reading is off. Ideally it would calculate boost using the SAE.MAP PID but that's not available on our car. So instead it calculates CALC.MAP using SAE.MAF, SAE.IAT, SAE.RPM, CONST.ENGINE_DISPLACEMENT, and CONST.VOLUMETRIC_EFFICIENCY. Since the SAE parameters are all available, we just have to put in the engine displacement (which is straightforward) and the volumetric efficiency in the vehicle settings. The tricky one is the volumetric efficiency. There are rough calculations you can do if you have your peak torque value. I'll have that after the tune tomorrow. I can calculate it off of my baseline run but that's not accurate with the turbo now installed. I might play with it a little tonight to see if I can dial it in by trial and error.
