How hot does the intake air get with a rear mount turbo? You would think the intake tube, being as long as it is, and the exhaust gas being as cooled down as it is in the rear that heat would bleed off as much if not more than an intercooler would with a header mounted turbo setup. I get you're probably not using aluminum to prototype the intake tube but that the IAT was still getting too hot is surprising to me.

i cant speak for the camaro but i did a rear mount on my vette and it always had much lower temps than any regular turbo or supercharger setup the tuner had worked with. I wish i could give better insight into the actual temps i just recall them being only slightly over ambient

I hope you prove out more than just it's as cheap as can be, before you start selling these to people. Seen countless guys start up one day, pull the wool over peoples eyes with hopes and dreams and then close shop a year later. Hunter Precision was huge on Camaro5 for a couple years when those cars were new and disappeared as the crap was hitting the fan. Not one of those kits still working on a car today and countless people out $5-6k. STS was around for years but that junk couldn't stand the test of time ether. We've built well over 10,000 turbo kits for use on daily driven cars for over 15yrs. It takes a lot of engineering, experience, testing, integrity and a huge investment to do it really right. I'm just looking out for the community as I've seen so many customers get financially ruined by cheap parts turning their car into a money pit.
Honestly, best of luck to you. You've got heart.

iats were hotter on mine because of my intercooler placement which was a experiment.

It has since been moved up to the front.

As far as who I am don't worry about me bud, I know who I am and what I do and I don't have to run this as my full time day job. If it was my day job I would have released the kit already and douched over people just as you had stated. Instead I have spent all my own money that I make at my day job (welder for a sheet metal company that builds stuff for hospitals, vettes, grocery stores, etc, also a robotics programmer).

I'm just a fabricator and designer that builds whatever he wants however he wants whenever he wants and doesn't care what people think. Infact I really enjoy a challenge so when I'm the only guy who manages to nail down the rear mount turbo (did pretty good so far, some improvements to make yes but pretty happy so far) then I will be even happier because I pulled off something everyone said couldn't be done.

i'd think most places aren't building their own turbos. So, source a good part. So around 1-2k there. The the rest of the 5-6k is the rest of the system (valves and tubing, tune and profit). Since it's remote, there is no expensive vehicle specific header needed. Might not even need an intercooler.

One could easily see being able to swing that without having to source parts that are inferior to the parts sourced for under-hood kits. The savings comes from not having to have vehicle specific parts machined (or cast) for you. With minor changes to the kit and some time on the dyno, the same basic kit could be used without refabrication of expensive vehicle specific parts, further driving down overhead costs.

I dont think you need to dive into refurbs or cheap chinese knockoffs for a rear mount kit to be 2-3k less than an under-hood kit (and significantly less when you add labor).

As far as cheap parts

All I use is name brand and you be the judge if my fabrication skills is "cheap"

I'm generally a custom one off fabricator. If I sell 10 of these a year I will be happy. I don't need to sell 10,000 of them so I can really dedicate my time to having a perfect part everytime.

bits of fab work in the shop and then some of my day job


Its easy to make a quality part, you use quality materials and think about simplicty.

For tubing I use 14 gauge 304 stainless on my y pipe and boost pipe to turbo, all quality vbands not cheap chinese made. We machine all our own parts, that is cnc milled not cheap laser cut. All stainless welds are fully backpurged with 100% beautiful penetration on every single weld.

No cheap nothing there.
Tial bov and wg
Borg Warner turbo s400 series (s300 series for road course cars or people not looking to ever exceed 800whp)
all professional made stainless braided oil to and return lines on turbo

I take great pride in what I do and never let a product out of my shop that I wouldn't personally run on my own car.

Fixturing is king if you want a repeatable part with great quality. I spend 2-3x the time building my fixtures than I do with building my prototype parts. Then I build a entire set out of the fixture and fully confirm everything is 100% good before I ever even say it is ready to go.

Want to source your own parts that's fine by me too. I can build just the plumbing if you think you can get a better deal than me on the parts.

I'm a easy guy to work with, I don't have to hassle nothing, heck if it never sells I really don't care because I'll be having fun with my own and I didn't have to pay some shop 10k for it

I did this for years (15 years) of being a professional automotive fabricator as my day job and I'm done with it being my day job. To many customers that know "how to build a race car, telling me what to do..." Thats fine, go deal with someone else. At this point in my life I build what I like and how I like it and if it goes anywhere I really don't care. The quality is there. As I said I got a day job and I really could care less what people think.

this is an interesting thread. I wish I could skip forward a few months and see some more data.

I have ran a number of turbo set ups from under the hood to low mount to rear mount. I really like the low mount best if they can be fit in that position. it seems like the ideal exhaust routing.

I think turbos are very forgiving as far as the set up goes. yes they will make more power if everything I optimized but even when many things seem wrong they still make a ton of power.

this right here is the winner

everyone knows that log manifolds are the worst for airflow yet there are tons of cars making 1000-2000 hp with them....

You can do a ton of things "wrong" and still make great power with a turbo. I'm just looking for a nice balance of getting things right in a package that is realistic and still able to make power.

Old saying in engineering:

You have 3 things to choose from. Quality, Price, and Production time. You can have only 2 at any one time.

If you want quality and cheap, production will be slow

If you want fast and cheap, quality will be low

If you want it fast and high quality, price will be high...

Not to offend you, or be disrespectful, but I can't help but notice how defensive you are. You spend a lot of time on this thread, stating how much you know, and what you have done in the past, with fabricating, and what not. To be honest, none of that matters to someone who has a pocket full of cash. People who are in the market will naturally assume you know what your doing if your selling a turbo kit that fits their application. I'm not saying that they don't care, or that it's not important to them. Merly that, in this thread, it comes across to me as a little too much.

For me, if I was in the market, and for the others who are in the market for a turbo setup, all I would want to see is numbers, what kind of quality was in the kit, and obviously cost.

People like Hellion, AGP, Whipple, and others, just simply post results. They don't spend too much time bragging on what they know. Especially when it comes to some of the opinions of people like Ted, and Kevin from AGP, those people have a sh!t ton of knowledge, and frankly know more about the topic, than most will ever forget. I appreciate what your doing, and am completely intrigued. I also have a ton of respect for you, for tackling a rear mount setup. In the end your product will sell itself, and word of mouth will spread like wildfire on this forum. You may think who the hell am I and what does my opinion matter, well I guess it really doesn't, I am nobody. Just a person who is on the outside looking in.

I just don't enjoy being told i have a cheap product.

Other than that I'm all open to criticism.

[gippy87]

Back on topic I'd think with that nice big open grill on the camaro the intercooler being placed up front would be a huge help for iat's.

I didn't get the impression that either of them said you had a cheap product.

For the avg guy, ton of money..ton of cost on shop time, no warantee on the powertrain (like an edelbrock or magneson provides) and in my 25 years of watching guys boost, along with 2 gos at it...a host of problems that never ends.

However- You have an awesome build, your skills are downright impressive and you have access to a shop to do this which is a major advantage. If I had access to you direct when I have issues, then this may make sense.

For a guy like me that farms this work out - and you should - and then inevitably adds more expensive parts - because you will - you are a few $1000 from a 2017 ZL1. Pricing came out recently. 650 HP, no fiddling and you are 100% covered.

I just dont get why people spend so much money to try and make something thats already available. If there was a 20 grand difference, then yes...but not in this case. Just an opinion, Im probably in the minority, but thats OK.
