You are correct.

You are correct.
Yep. This is why when I go E85 I am going to ditch my KC and just go with a trunk mount set up, since keeping close track of IAT2s wont be as important.
Nope. I actually brought this up in the thread back on 9-27 on page 1. E85 use should be no problem being off a few degrees because you'll never come close to pulling timing anyways.
Also, for new vmp owners that under warranty, pretty sure warranty is voided if you mill it. Of course, the warranty is only one year, so many are past it anyways or possibly don't care about it....but some new owners might. That's the reason an extended sensor offering would be really great. Plus you don't cosmetically affect the blower.
I was looking into a longer sensor myself for a while. It would have to be a MAP/IAT sensor combo and have the same calibration. I'm going order a cheap sensor and try modding it to extend the IAT tip.

I suppose for the majority of E85 users they may not care. For someone like myself who's spent a lot time, money and research getting IAT2 temps down it does matter. My car is data logging every time I drive and I spend a fair amount of time reviewing data logs and comparing conditions, driving habits and various pulls and runs. Having accurate data matters to me. BTW it's more than just a few degrees off.
One thing that frustrated me switching from the Whipple to the TVS was how the TVS IAT2 didn't hardly fluctuate compare to the Whipple. It would heat soak and then barely move. Killer chiller on or off, WOT, cruising. This explains why. The sensor is buried in the metal casing and is reflecting the temp of the casing more than the actual IAT2 temps for the most part. At one point I even thought my IAT2 sensor had gone bad due to the results I was getting on the TVS vs the Whipple and I swapped sensors with no change in behavior. You can be sure I'll be machining down the IAT2 mount location on my TVS
I'm also getting mine machined down before the install. This info was a great find for us as far as I'm concerned. My car will be mostly run on e-85 but it will also have a pump gas tune for it, just incase I get caught out and no e-85 is available. I'd like for the tune to be as correct as possible on gas also as it can be.

You are the exception. Most of us don't data log and change things just as a "experiment" like you do.
I can see why some may go and have this done. But for myself, not worth pulling the blower just to do it.
My temps with the tvs blower has been pretty consistent with what the Eaton was. Who knows, maybe it's a tad lower or higher. But I won't lose any sleep over it.
I’ve data logged as well, the Kc works well for the ported eaton keeping the iat2 at 96*. I can’t see putting on a tvs and that number going up. VMP I’m sure isn’t manufacturing these, i Eaton’s made this and now it’s the consumers problem.
You'd be surprised. I ran a very aggressive upper/lower setup on my Eaton and never had an issue with heat but this TVS just runs so much hotter than my Eaton did and my intercooler system is vastly superior now too.

Brady, he is NOT the exception. The majority of Cobra enthusiasts I talk to data log. These guys are constantly modding and seeking ways to improve their cars chasing speed, racing and better ET's. I would say you are the exception because you have said you do not take it to the track, push it hard on the street or do anything besides spirited back country WOT pulls in the cold MN northern air.
When you are "bout that action boss" getting plenty of street and track seat time...this design flaw matters. The rest of us are spending coin trying to improve IAT's with trunk mount tanks, stewart EMP pumps, j2fabrication intercooler mods etc and are seeing big improvements. I would like to see VMP come up with a solution for this, like an extended IAT sensor which would represent additional sales and revenue for them, before I mill down my case and give them a free pass. I'm just surprised this was not corrected with their "Gen 2" revision. I'm still a fan and its a great blower, i just do not have any interest in monitoring the heat of the case when I believed I was monitoring my IAT2's. Sub'n for updates.

Keep the forum updated on how that turns out, great idea and others that don't like that idea of milling will certainly be interested.
I wouldn't advise anyone to hold their breath that vmp is going to "recall" blowers or change the production of the gen 2. This is it. 03/04 cobra owners are lucky they made the blower at all....the market is tiny. Way more money to be made with the 5.0 market. They're not going to recall these and lose a dime. You're stuck with what you have and only option is modify it yourself.
This is the truth. We are lucky that a company decided to manufacture a blower just for us, we are such a small market compared to GT500 and Coyote production. It seems like this is something we will have to tackle as a community.
What's this justin's cooling mod you guys are talking about? I got a pos 2v in a truck, so im opened to anything. I log the hell out of my charge temps. For example, 180° + IAT2's after the 2-3 shift last friday at the track sucks.
I just rather monitor my IC pump via reading my IAT2's on my interceptor but good idea. The light would annoy me unless it's set to only light up when there's no flow.

I don't think he makes anything for the Lightning crowd. You can try and contact him though. J2 Fabrication.

Well I personally still think Malcolm is. He changes more things and does testing than many others I see.
There are plenty of non track tvs guys running e85 on the street solely driving as a weekend cruiser.
I like to know what it is for the termi crowd to see if it's worth it for my truck. I dont need him to make it for me necessarily.
This is the mod:

plus or minus the crazy re-flashed Lingenfelter pump
Thank you. Looks like what i have planned will be superior. (after market intercooler, better whipple midplate and i already have a better than stock IC pump)
You still need air flow with that. So at the track in traffic, i dont see it helping that much.
I would think the Lightning has a little more flexibility due to the in/outlet location compared to the Cobra.
Ya, I thnk that's also the reason you won't see the larger 2650 get offered in the 03/04 platform....the market is 15 yrs old and too small, they've also already sold many 2.3s some people aren't getting rid of, and there's more money to be made elsewhere.
And back to the iat2 sensor issue....they'll never "recall" or change anything....why would they? They'll point to examples like your car running 10.60s @ 133 on 91 pump gas on a 16 degree tune and say "how can there be anything wrong?!?......case dismissed!"
LOL
