Chosing between a non-charge cooled TVS1320 or a non-charge cooled TVS1900 is easy if money is no objection. That TVS1900 will spin a lot slower but still shifts a bigger volume of air, hence keeping it a lot cooler. What do you mean "SSC without TVS1900"; just a remap and a bigger crank pulley (just like the komotec offering)? In such case, I would go for neither.

@nordschleife666 that body line mysteriously disappeared between November 12th and November 13th 😀

if the starter motor wasn't even turning over, then to me that most def sounds like a battery problem. Like I said, the engine MUST fire without the MAF.

Override the valve to keep it open to stay in quiet mode. You need one 12V+ cable and a switch to the solenoid. Job done.

@PJ - the car should start without the MAF connected; but will run rough. From experience I know that running the engine just a few seconds without the MAF (it is quickly clear something is not right) doesn't even throw a code. All should be OK after you plug in the MAF. If there is a persistent code, you can read it and clear. You can also try 5 key on/key off's without starting the engine to see if it clears any non-persistent code. The dash issue shouldn't be related at all. Albeit very strange that it now occurs after your mishap on the MAF. Didn't you have the V1 of the CAI installed? On a non related side note, good to see that air straightener is now part of the V2 design 😉

Will be a blast to drive! And many thanks for the views of SCS/24-7, appreciated.

No critism whatsoever, just want to understand some things and more important for you to to have a super experience. As you are, together with some others on here, pioneering in pushing the 2gr-fe engine further. Just needs to be safe. Please share the SCS/24-7 views. 👍

Thanks for this info. Just don't understand why you would the AFRs to go up after 6.4k. "In the old days" running lambda 0.86 (providing I read your graph ok) on pump gas means an AFR of 12.64:1 at 7k rpm... for me that is close to piston melting territory on any boosted engine and too much out of the "comfort zone" (11.5-12:1 or abouts on a boosted application). Wouldn't say that is a conservative map re. AFR's. But what do I know 😉 I am sure your tuner knows what he's doing and that they checked the exhaust gas temps. Good to read this kind of stuff. Thanks!

What is their take on lambda being upwards of 0.85 at redline and going up from 6.4k onwards? Doesn't that seem a bit lean for a roots type blower application? Just curious to know.

@steveoexige The pipe is perforated so the sound does get absorbed somewhat.

I saw that post on Facebook too.... There is NO packing material in the OEM box; nothing has been burned away 😉

Eltech one is also done in V-shaped carbon upon request. Just see DixieV6 post... Nice detail: the Eltech one is made from an OEM mould...supplied by Dixie to Matteo... Small world.

@Exx so then get the OEM one... your dealer can deliver you one for 2335€, vat included, striker pins included, mesh included. As it's the OEM one, the carbon is diagonal (so no V-shape, but others might correct me as I am not 100% sure). If you take a membership here, there is a discount available. The Deroure one is OEM too. The Komotec one is OEM too as far as I know? That being said, DixieV6 has the Eltech one (=aftermarket), V-shaped carbon and that one looks very nice too. I have the WinAce GRP one (=aftermarket), which I had completely resanded, repainted. Aftermarket all need some fiddling IMHO, but come out real good. Your requirements = get OEM one.

Wow, what makes me then; driving around with straight pipes 😉. If you look for "noise levels", need to also replace the manifolds to real headers.

Yes

@Doug Ashley the only extra step with a valved exhaust is you need to "pull the vacuum tube of your original exhaust and put it back on the aftermarket one". Takes at least an additional 15 seconds 😅...

Looking good underneath!!

I have been thinking about this one. Could be worth checking out the supercharger pressure relief valve/actuator thingy too; just as a thought. It's near the throttle body. Suggest holding the rod to see if it makes any difference in noise (I was thinking in the direction of pressure builts up, gets relieved (too soon) and noise changes, repeat)

@3eighty sorry, I am on BC Forged wheels now, no need for spacers anymore.

@NANO, I think you have that backwards; pops & bangs galore in above setups. (on a side note, don't want to pollute GF's post, but my exhaust goes: long tube headers, decat, and depending on fully controlable valve position: straight pipes (so nothing there to muffle anything 😀) or absorption muffler. So pretty confident that's about as loud as you can go. Oh, and did I say pops & bangs galore AND flames??😀.) Back ontopic. (sry for that) @GFWilliams like the electric vacuum pump idea, but can't you use the vacuum canister that comes with the KT air intake and use it with a normally open solenoid? The time for it to loose vacuum will also be the time for the engine to cool down and in that case it doesn't do the stupid "Rev up on Engine on thing"?

Sry, no idea, would guess around 8-9 mm? For me up to 5mm as non-hubcentric and again starting from 13mm as hub-centric (with lip) spacers are available (out of the top of my head)?

5mm non-hubcentric spacer works without issue. Have run them for over a year. Get longer bolts.

Would suggest to use an automotive stethoscope to try to pinpoint the culprit?

If you use it with the OEM manifolds (with integrated cats) the answer is NO. (but you'll already have 'a decat' pipe in place in that case. It's just the s-pipe that connects the OEM manifolds to the back box) But you want to be running real manifolds, meaning that NO cats are in place IF you use a decat pipe (what's in a word ;-)) then the answer is most definitely YES.

@GFWilliams we might need to enter into a competition.... oh wait, there is nothing restrictive/noise muffling anymore for me to delete from my current exhaust setup 😂 Good to read the 4xx back box and catless "Jim S-bend" (and KT headers, right) work their magic 😉
