Car was a beast and ran mid 11's at 119mph with ease. With the above mods however came issues related to failing catalysts and the weak point of failing Heat Exchangers of which there was one on either side under the supercharger. They are simliar to the left and right side air coolers near the turbos on to of the VR motor. They would fail and leak coolant down onto the cylinders causing fouled plugs and misfires.

What types of impacts on EGT and cooling system concerns are present with the JB1 Piggyback? Seems like many here have been running this set up since last summer which is fine, but what about longer term impacts? It took 20,000 miles before any issues on my Audi but with the turbo's here already spinning at 220k how much more heat is being pushed through adding 3psi?

Sorry to come in so late with basic Q's but I appreciate the feedback as I'd love to up the power in my 2018 Redsport AWD a bit. Especially down low.
Welcome to the VR30 forum!
20k miles on the Audi? Do you beat the heck of that car ?
It will be nice to hear from members here that has 2016-17 VR 3.0
that frequently go to the drag strip using the JB4 or drive aggressively.

BTW, I’m on JB4 luxe AWD +7 psi. I only save the power when I get bullied by a Honda civic with 600 hp window stickers.

Kidding aside , I just need a passing power and probably like to suprise some trucks (FORD V6 TT etc) here in SE WI who simetimes bully most 4 door sedan with wheels..

No, I drove it with spirit and did visit Mid Ohio and the drag strip twice per year but overall EGT's would approach 1,200* + often due to the boost going through her. It's not uncoming that dual pulley or ultracharged units would melt cats within months. Keep in mind 25-27% higher rpms on the blower turned it into a real hair dryer. The car was kept stock until 7,000 miles so when I sold it at 27k just recently it still had the stock cats but was not happy with them.

yeah please do a log for the map 7 on just 93 pump gas, really curious how the car performs, i live in nyc so for me i don't punch it like that every road i take but like someone said to do a pass by. i'm pretty sure i can get away with it now with my mods and cold temperatures but summer time here it gets to 80's 90's

Does anyone where have experience with exhaust cut outs? To bypass the stock muffler? (in conjunction with a aftermarket ** and exhaust...)

I"m curious about any HP gain and reliability.

I like the idea of the car sounding loud at times and then being able to quiet it down when needed.

i think with this engine the exhaust can not get that loud compared to the naturally aspirated. i have some video clips on youtube with an exhaust i currently have on. it's loud around 3000 rpms but after that it's not that loud

https://youtu.be/iH5W-SXcLvw

that's my latest video with take off with mods i have as of now. my brother recorded it but he said it doesn't sound as loud on video, in person it sounds louder

If you wanted more volume, you could snip the resonators off of your Top Speed.

You can hear the turbo's spool quite nicely when you take off.

Really?? I donít know honestly, I thought about it but I donít want a drone either. Is there a video online comparing it??

Just found a 370z video of the top speed exhaust with resonator delete, wow sounds awesome, might consider!!

You're like one of the only ones with this setup on a 3.0T. It should cost about $100 for a muffler shop to cut it, and weld in piping.

I wouldn't use the 370z video as a reference, completely different engine than ours. If you were to delete the resonators, keep them just in case you want to put them back on.

For some weird reason, I like the 3.0t exhaust quietness. I kind of like the sleeper approach. I wish I could tone it down a bit more on WOT! LOL!

I don't have resonators...and I like the sound....I just wish it was louder at WOT as well...

Hence the cut outs. That way I can control it...

I think only you can determine what's best for your driving style.

Map 6 allows you to enter boost by RPM which is good as nissan is already pushing the tiny turbos to its limit on RS models. Hence, tapering off at the high RPM would be a good idea.

Read on stillen blog for more details and spend some time understanding the efficiency island they pictured there:

Good information. So why is it the JB1 is just a flat 3psi bump all the way up and not jistnprogramed to taper off? It would seem best to do that out of the box as i have no interest in toying around with a JB4 and all it can do. Ideally, i want a plug and play solution but not one that is at the top end going to be too high?

I may have an opinion why but I don't speak for Terry or Burger Tuning for that matter. Best to ask Terry himself

Luxe AWD from the stop light- I think this was from stand still to 50 or 60 mph... 93 Octane with E25 fuel.
Map 6. So no matter how high the target boost is the ECu controls the base PSI and also how efficient the tiny turbo build pressure.
I also noticed that my AFR are leaner (low 13’s on the lower RPM) vs when I had just the full Shell 93 Octane. I might change the 1.5k to 2k RPM into 6.0 and 6.5 respectively.

Awgdi....after the shift in that last graph your starting to run a bit rich...how's your timing look?

And to the guy with the s4 (nice car btw) would it matter that for for 3.0 it's a turbo...and therefore they aren't always spinning or putting out less boost? While an SC is always "on"? Truthfully I don't know if Superchargers have any sort of wastegate.

Thanks on the S4 props. She was a blast for sure. I miss the DSG more than the power honestly. In terms of bleeding boost, yes the S/C S4 does bleed boost. Stage 1 there basically holds boost longer and adding a DSG Tune for the transmission speeds up shifts but move the shift points to 7,200rpm like the 6spds. Stage 1 puts the S4 at the performance levels of the RedSport with just a little less MPH in the 1320ft runs. Typically Stage 1 cars run 12.7's at 109-110mph. Stage 2 puts them at 12.2 @ 112-113mph. Dual Pulley typically moves them to mid 11's at 117-119mph but there are various ratios which can do more. All this at on pump 93. On the street they are beasts. In street trim, nothing short of another German car with AWD or a Tesla would move-out any better from a dig. Instant boost and gobs of torque are awesome on a daily.

In terms of mods on my RS400, I"m not concerned about the boost levels down low. Yes, spinning the turbo's faster down low with an extra 3psi will cause more wear over the long-haul, I don't foresee a problem in the first 3yrs or so. It's the boost boost levels up top on the Redsport that I think will matter. Pushing them to 17.5lbs from 5500 to 7000 doesn't seem like much but that's a lot of heat over time that could impact their life and cause issues similar to what happened on my Dual Pulley S4. On the Audi the mods taxed the cooling system just before the intakes thus why the heat ex changers fail and it definitely cooked the cats. The S4 guys are still working on aftermarket heat exchangers that will tolerate the dual pulley set up.

Overall here, I just would feel better knowing the car has more boost down low and not much above stock up-top. Either way, if there's a turbo failure or major issue, the dealer can scan the ECU and see the additional boost thus voiding a warranty but the key is to avoid such repair right? I'm leasing mine, so I need it to last to 36 months at least.

I don't know enough about boost controllers like the JB1 or JB4 but I do know I won't play around with them like many here will, I just want to set them one time and be done. I'll likely pull it off in the winter months when the power isn't even needed. Especially on snowy days like this week is bringing us.

So if you have a JB4 and can monitor IAT isn't that a reflection of the EGT? And as long as your IAT is not increasing substantially over ambient then you are not causing any harm to the cooling and exhaust system?

I'm in OH as well and it's been pretty cold since I've installed the JB4, but I've noticed under normal driving I can be anywhere from 4-12 degrees above ambient temp. It goes up when stopped and down when driving as expected. I haven't seen anything dramatic as far as increase in IAT even after several consecutive 7 psi over stock pulls.

These are just my assumptions, but if someone could chime in with more experience that would be helpful. I guess my main question is when to be concerned about heat or cooling system damage, 15, 20 degrees over ambient?
