High boost TVS guys in here please

plus or minus the crazy re-flashed Lingenfelter pump

FYI.....The pump is from Stewart and they are all the "hotrodded" version now. Stewart reprograms the pumps themselves.

In theory the EMP pumps are even better stock now than the old lingenfelter reprogrammed versions. Back when they were shipping programmed at 9 amps lingenfelter was reprogramming them to 19 amps and selling them for a premium. EMP caught on and now ships them programmed at 25 amps from the factory.

How much are they from Stewart now?

Much cheaper through a reseller than directly from EMP / Stewart.

$454.97 from Summit. Seems price came down. Back when I bought mine they were more like $500

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.

Joe, I’m definitely having the flange milled down very soon, just put the car away today from the northern salt fest. I just commend you on your tenacity to find the source of your questions was a design over site, for that I thank you because you saved me from pulling out my remaining hair plugs when our iat2 would have gone up.

No problem, happy to help, I love doing this stuff.

The intent of me posting my findings was not to point a finger or tell people what they should do. I just wanted to show the facts. If people decide to mill the blower, great.....if not that is fine too. To each his own.

Any possibility of modifying an IAT2 sensor or finding an aftermarket replacement so that it'll sit farther into the airstream? Given that it'll take me several hours to remove the blower, several hours to reinstall it, plus whatever a machine shop charges, I'd happily pay a hundred bucks for a sensor that would give accurate IAT2 temps and negate the need for the blower R&R.

You can try but I didn't see a way without doing it "half assed". The sensor has a plastic cage around it so you have to trim that off then you have to figure out how to extend the wire itself, which there is zero slack. I did not find an aftermarket sensor that was for IAT and MAP like ours, maybe you can though.

So the IAT2 sensor does MAP and IAT2?

How would one even start looking for a comparable sensor?

I actually got very close a few weeks ago. I went and purchased the cheapest one I could find on eBay. Extended it, used epoxy and scrap plastic to extend the cage, and tried to install it after letting it cure and grinding down some of the excess epoxy. The one I bought had a slightly thicker o-ring which made it harder to go in. I tried tapping it in at an angle and that caused the epoxy to crack. Nothing fell in and I just put the old sensor back. Here are pics. I was very upset because I didn't realize how annoying it was to get to that sensor with everything together (and with EGR). I'm considering buying a matching OEM one and trying one more time. I only lost about $15 on the last one.

You might be on to something there...

I certainly applaud the effort but I'd also be very cautious going that route. Luckily the epoxy cracked on installation and not later sending debris through the motor. You could be pulling off a lot more than the blower to fix it.

Yeah, I think it was more a result of me tapping on the sensor. The sensor I bought was a much tighter fit with that o-ring than the stock one. I'm thinking about trying again with the exact same one. Now that it is cold IAT2 temps are always well below the threshold, but still would like to get it done before it gets too cold to work on the car.

I’d love a longer sensor option but I would not be comfortable with modding a sensor for the reasons Malcolm posted. My blower is coming off within the next couple of weeks for Justin’s Intercooler mod. I’ll be milling down the boss for the sensor at the same time.

That's a very good point, and something I was thinking about as well.

Screw it, maybe I should just plan to pull the blower again.
