Prosport EGT Gauge Installed

[aaronc7]

***Disclaimer***
Tapping the manifold this way can theoretically mess up your turbo by sending metal shards through it. What I have read and seen myself is though that it works out perfectly safe and fine. If you're unsure, try a google search. If you're still worried, then just take the manifold off already

Let me first say I will be back tomorrow to finish this post. Wanted to get most of it on here while it's on my mind.. but I still need to take pics of the wiring and stuff, and definitely don't feel like going back outside to the car right now, lol.

This was my first time ever tapping and drilling and to my surprise it came out very good. I did practice first before doing the real thing..... meth injected cat!!!



As far as drill bits and taps you'll need.... 11/32" drill bit and 1/8 NPT tap. As you'll see in my pics, before I started really drilling I started a little hold to help guide the big 11/32" bit... started iwth smallest and slowly worked my way up. Then once I was up to the 11/32 I slowly drilled my way in.



1st bit


2nd


I think this is the final bit, didnt take pic of 3rd


You'll wanna use a WD40 during this too... Once I felt like I was close to the breaking the surface, I started the car up (the mani gets hot fast) and drilled the rest of the way. lol one of my intercooler pipes was totally disconnected too (was in the way to drill), but it actually idled okay. It did die once randomly but started right back up.



Drilling complete


I let the mani cool off, put some thick grease (stuff i used for the shifter) on the tap and slowlyyyy (it took forever) tapped it. BTW philly that tool you said I need to get didnt fucking work, asshole. lol but i got somethign figured out.



I spent a good bit of time figuring out how thick the stock mani is based on number of threads, etc and ended up tapping the hole such that the EGT probe sat about this far into the mani so that it would not be sticking way out inside the mani



Also took some measurements on the diameter of the mani at the point I drilled....came out to like 1.5" of open space, I had my probe protrude about 1" into the open space of the mani



Here is how I did the wiring... I used A/C fuse so the gauge would come on in the "ON" position. The actual instructions call for "accessory", but I figured the speedo and tach come on with "ON" might as well make the gauge do that too. If you want to have it come on with accessory, use the RADIO fuse. I used the HORN fuse for constant power.



cruising down the highway.... then 4th gear pull I saw a 1650 EGT!

Ugh, what a long day. But it (I think) was worth it.

You better take nice pictures of my baller-ass wiring job with plentiful amounts of zip-ties

And I present to you, the first VW Speed 3:

[aaronc7]

oh yeah a HUGE thanks goes out to sith for the help!!!!!!!!!!!!! It was a long day

[Sixth Gear]

I do what I can

[aaronc7]

If you need help installing that supercharger just let me know

oh wait...

[Sixth Gear]

Hurr hurr. You so funny.

Don't worry, we'll meet up in a few years with my R32T and see whats what

[phillyb]

lol...the handle?
whatever

[Haltech]

Philly is a fuckin idiot sometimes... he linked you to the tool that holds a DIE, not a tap. The tap requires a T=Handle.

[aaronc7]

I think the NPT taps they had were not for the t handle tools....was WAY to big. I got the biggest t handle and the tap end was still too huge. I ended up using a regular open socket and the drill actually worked too (really slow and carefully) for the beginning of the EGT and the meth nozzle tapping. The drill did not have enough juice for the end of the EGT tapping. That's when I had to break out the guns (lol).

[phillyb]

yes, but first i mentioned a handle. and for the record, i don't read labels, i look at what it's in the package. and a t handle, which is still what aaron got, not the thing i linked, and the thing i linked look a hell of a lot to me.

furthermore, this is why i come with some interesting food after a visit to the grocery store

Yea, kind of reminds me when i needed to wire you car. I asked for a butane soldering iron.. you came back with a torch so i could heat up the soldering iron that had no electricity to plug it in. I can only imagine what you bring home from the grocery store when the girlfriend specifies certain items.

[phillyb]

d00d srsly. i've home with tons of weird shit. or like almost right stuff

[Lex]

Good job. 1650 F EGTs aren't too crazy at the manifold.

[phantom3]

For the love of all that is holy.... Please tell me you did not drill and tap your mani while it was still on the car. That`s a big dumb fucking mistake. From what i can gather you started the car while drilling... wow... I hope your turbo explodes due to your Lazyness. Seriously!... Fuck!...

[phantom3]

Oh and for future reference, a center drill is the proper tool to start a hole with. http://grizzly.com/images/pics/jpeg288/h/h4457.jpg They come in different sizes. But if you wanted to get really anal, you should `spot face`a casting before you center drill it. But most of all YOU REMOVE THE DAMN MANIFOLD FROM THE CAR YOU DUMBASS!

[smakdown61]

While I'm not going to bash you like phantom lol, weren't you worried about metal flakes getting into the manifold (and then turbo) while drilling? Especially when the car was running?

[aaronc7]

I asked around and LOTS of people install and drill this way. It's not ideal, but the point of the engine running is that most if not all of little shards at the end will get blown out of the manifold, through the hole, not into the turbo. Anyone who has actually done it has never have problems... Kinda followed this guide

EVO Motorsports - Evo VIII Performance Upgrades and Accessories - EGT Gauge Install

[bova]

wouldn't they blow from the manifold into the turbo? seems like risky business to me. but i guess it worked so thats good.

Yeah I see what you're saying. I guess if people have done successfully, including yourself without any problems, it can be done.

[aaronc7]

everywhere I looked on the web and asked people who have done it...no one has had a single issue. So I saw no reason to make it any harder than it needed to be. and yeah the car is running fine

[Grim]

thats how alot of ppl do it

[fbpem1]

heres the tool that you wanted or rather combination of tools that you wanted fuck a t handle for holding taps i hate them, this is what i use when i need to tap something, sorry for the crap picture still getting used to this new phone..

[skeeter149]

aaron i wish you luck my prosport egt on my nissan started dying after 6 months and was dead at 9. when it started dying it would go to like 200 shoot up to 2200 then either 0 out or max out. then it just would always stay at max. i swore never to go prosport again and so far so good with out em. but again good luck just me wooden nickel of sence.

[08_ms3_gt]

congrats on the install. interesting technique - i understand how other people have done it with success yet am still a bit skeptical.. but if it works, it works.

just for the sake of curiosity - in a case such as this, has anyone considered using a magnet or vacuum source of some sort to complete the tap? maybe there's a tuner shop out there with a 'secret' method. but a rare earth magnet would prolly do the trick if the manifold is cast iron. just leave it attached near the tapping point, then, once the hole is drilled, drag it towards the hole and it should bring the shavings out..?

Haha, that's pretty much what I ended up doing. Look at the bottom of this pic, you can see the combination of misc adapters and I think it was a 3/8" 12 point socket. Worked just fine.

Well, I did see a few posts like this on the interweb before I got the gauge at another forum. I've dealt with prosport before and at least their support is A+. The posts I read online who had the issues, they sent him a new probe ASAP for free. I guess I will cross my fingers but at least I know if I do have issues they will take care of me. on a side note, I really like prosports because they match our interior so well

Oh, I know this method is not the ideal way. But, there was are tons of people who have done it and no issues, so I figured why make it harder than I need to. It's not like I am building an F1 car or something.

[skeeter149]

aaron you are the man and again may it last you many years of good service and accurate readouts

Seriously, stop being a stupid fucking troll. For one, the backpressure when we were drilling (I did the final drill through the last stages) was enough to force quite a bit of exhaust gas back out through the hole and prevent any shavings from going through. And second, who made you the expert on drilling and tapping into the manifold? I would be willing to bet there would be more leftover shavings in the manifold if we had spent the 5 hours fighting to get it out. Also, the way we tapped it, we had quite a bit of grease on the actual tap to prevent any shavings from entering the manifold.

Go back to sucking your donkey dick, asshole.

[phantom3]

It not a matter of building an F1 car... I mean do you really want to risk your turbo or such a little job? It would take an extra hour to remove the manifold and complete the operation with no risk to the turbo. What if it had gone the other way? I'm pretty sure you would be kicking your self saying " Why the fuck did I do that?!? that was stupid!" It's just not a shortcut worth considering IMO. It also would have been easier to tap off of the engine.

Sorry i came down hard. As a machinist i have an extremely high level of anal retentiveness. I get really pissed off when i see half ass work that is easily avoided with a little preparation.

Good luck with the setup.

Sixth Gear - "And second, who made you the expert on drilling and tapping into the manifold? "... Trade school, Provincial Ticket, Red seal, and 8 years of machining experience qualifies me to speak about drilling and taping a casting.

I apologize for not posting my profession in my profile.

I also apologize for coming down excessively hard. But judging by the techniques used to install this probe, No one present was qualified or even experienced enough to do this installation. Anyone with proper experience would have removed the manifold knowing the risk it too great. Don't get me wrong I'm glad that a piece of swarf didn't fuck up aaronc7's turbo. I just fully believe in doing a job correctly. As for being a "Troll" this is the first time on this forum that i have jumped on someone like this.

-David

[aaronc7]

Pretty sure it would be more than an extra hour of work . lol

alright though, fair enough. Im sure i would be pretty pissed at myself if it came out bad... but based on my own research it seemed to be 99.9 percent fine and safe

[phantom3]

I'm not trying to drag this or rub it in but when a drill breaks through the opposing side of a work piece, (in this case the internal passage in the manifold) the swarf is bent away from the hole... even though the exhaust gasses are blowing out the hole there is still are huge risk of swarf passing into the turbo.

[aaronc7]

disclaimer added in first post

[phantom3]

I noticed that.... lol

Thank you

[kopf]

I've seen the diesel powerstroke guys use this method for putting in egt's. Though they recommended the wax for your tap, that tends to catch a lot more than grease it seems

[wassup61]

Aaron, when you get the chance, can you log EGT vs cat temp bank 1 via the DH. Lets see if we can settle this EGT correlation once and for all.

[LBV]

^^ + 100

[aaronc7]

yeah I can do that... i am curious too.

EGTs rise and fall a lot faster than the DH cat temps do. You can do a 4th gear pull and see 1600ish in EGT, then 10 seconds later if you're just coasted you'll be at 1200, with the DH it takes forever for temp to rise or fall comparatively, I guess something to do w/ the algorithm it uses... but yeah I'll check it out

[GQ_WhiteMS3]

probably more likely to do with the dash hawk reading the cat sensor and the cat probably holds heat more.

[aaronc7]

updated first post with how i wired the thing

Have you had a chance to compare aaron? If you can't datalog both at the same time, maybe do a video of the DH and Prosport gauge together?? Thx
