3.3TT Mishimoto's Stinger GT Intercooler Kit R&D Thread

[Slow jams]

@motto hey Nick What’s up any new info? “Cough cough” intercooler

 

[JDM_Man]

Looks like Nick made a new post in the engineering blog. Can be seen below...

Float like a Butterfly, Sting like a Kia? – Performance Intercooler R&D, Part 6 – Blow-Off Valve Adapter


Not much new info on the actual intercooler or piping, but they go into a lot of detail about using a blow off valve vs the OEM diverter valves. Worth a read. But, in my opinion, a waste of time to mess with aftermarket BOV's. Mishi themselves showed that the most popular BOV's that many Stinger enthusiasts are using right now actually are slower than the stock diverter valves. Pretty dang nice to have some actual test results on OEM vs aftermarket BOV's.


@Mishimoto - would it be possible to just buy the new merge pipe complete with the associated couplers?



Edit: I posted the wrong link at first, also added some thoughts.

While they may be faster they are also made of plastic lol. Don't trust plastic diverter valves, HKS are pretty quick same with synchronic bov by synapse which is almost instant. They are both pull type BOV which work better for this.

So is all this blow off valve research really needed?

Plastic = lighter weight. No reports of failure that I've heard of on our engines.

Those other brands may say that they're faster, but the evidence shows that OEM is the quickest for this engine.

The only reason to change to a BOV is for the sound and/or engine bay dress up. Nothing wrong with that! But it's not gonna make your car any faster.


Edit: grammar, clarification.

Hey Guys!

Sorry for the absence there for a bit, but I'm back to give you an update and answer your questions!

So first up, info on the intercooler is coming between today and tomorrow! We have all of the testing results compiled which will be launching as soon as we get a few things wrapped up for the full blog post. I'll make sure to bump this up again with the link.

Second - Yup we launched a post on our BOV adaptor flange along with some testing that we performed with the help from our friends at Tial! Since the Stinger has a build in system for protecting against compressor surge, some of the higher rated BOVs like Tial's Q valve operates on a slight delay, or not at all when tied into that system. We found that using a lower rated BOV or bypassing the solenoid and built in vacuum chamber would help the BOV operate as intended. The stock system is also very quick acting, given its built in system, and being calibrated specifically for this engine, but knowing stock plastic recirculation valves in general there is a risk of leaking down the line (even though that the stock valves on the Stinger are pretty robust), not to mention the added soundtrack that venting to atmosphere provides. For more, make sure that you check out the full post on our Engineering Blog!

Finally just wanted to give @Toddasaurus a shoutout for his insight on this thread over the last couple days!

Thanks again for your patience guys! Make sure that you stay tuned for the data post on our intercooler testing coming VERY soon!

@Mishimoto Is it possible to NOT have a BOV flange on the charge pipe so that one could have one welded onto the cold pipe?

So in the general design of our merger pipe we incorporated the flange for the fitment with stock equipment. As long as as you have a good seal, you can block those off and relocate the BOV easily

Very interesting. I do have a TiAL Q valve on my car for sometime now, and you can barely hear it. Can you please share how to route it directly and bypass the stock system.

Also, for the QRJ, would you mind posting vids on how it sounds and which spring should we go for 1.5 or 3 psi?

@motto Nick your Slippin...
Come on dude post the specs we would greatly appreciated it

....How hard is it to post results

 

[JDM_Man]

Wagner tuning intercooler it is

I feel the same way... Disappointed

 

[JDM_Man]

Strung us along too much sorry @Mishimoto

At this point I have yet to see decent customer service...not a good look...

 

[xot1]

No much consideration for customers.

 

[JDM_Man]

Everyone who would have bought the mishimoto kit is going to buy something else or get a new car by the time this comes out lol...

Have to agree ...Also I find it very strange How a company can’t post spec’s ....It makes me think two things one ...factory is better...two Maybe Company can justify the upgrade?

 

[xot1]

It takes less than 1h to make excel charts, a quick write up and post them. This is a joke.

What’s funny it’s a great car regardless...With a tune it’s a beast Intercooler is nice but... Sometimes you just Gotta know when to let it go
