Boondockers turbo upgrade

Anyone have any input or experience with this bolt on turbo upgrade? It looks to be about $2,100 and includes new turbo, turbo manifold, clutch, head gasket, and dynojet tuner. It says it comes with 3 tunes. Stock +5hp, dominator +35 hp, and max at +50hp @ 100 oct. Says 187hp on pump dominator tune and 208 on 100oct. I’m curious if that’s whp or crank.

Seems like you make the same numbers with just a stage 2 tune (2016 xpt BMP tune)

Following, I have this Turbo on my car but I'll hold off before giving any of my thoughts....

Regarding their Advertised HP numbers, they are claiming those are WHP NOT Crank... BUT, dyno numbers are no good if you don't know what the actual Delta is and able to compare what that specific dyno shows for a stock car.

Now, on their specific Dyno a 2017 XPT makes If i remember correctly 159whp (right wrong or indifferent that's what it reads) so when a claimed 187whp is an actual gain/delta of 28whp and so on for the other tunes.

Also, regarding the OP's comment about the Head gasket.. The kit does not come with a head gasket, it comes with an exhaust manifold gasket.

Haha ya your right, Manifold gasket, I looked quickly, figured it was head gasket for more boost. Funny how much dynos differ. BMP gets 110whp out of a 16 turbo and 127whp out of a 17 xpt

They just released these kits so it may be a little bit before we see real world numbers. I have a couple buddies installing them on 17xpt's but we're into the cold and rain season here so they probably wont see any action until this spring. For the price this does seem like a hell of a deal. Others big turbo kits (not a upgraded stock turbo) are in the 4-5k range.

I’m erring on the high side of AA’s tunes. If his numbers are close on the dyno that would put me around 165 to 170 rwhp. At 2100 for 39 more HP that would be a significant increase. E85 with a tune and stock turbo should push you close to 200HP. Not sure why they did not go with E85 unless the injectors are not big enough.

17 stock injectors are not big enough for e85. Need at least 850cc for lower power on e85. Stock I believe are 700cc.

I've talked with Mike from AA a few times, I believe his tunes are around +25ish WHP over stock on 91oct.. When I tested an EVO stage 2 on my car with similar claims it made 147whp on the KMS Dyno, right in line with Evos claims. I would say with a 91oct AA tune you're gunna be in that same realm of power

I just looked at AA's site, his Stage 5 tune requires 110oct. to yield about 35-40whp. With that, Yes, you're most likely in the 160-165whp range.

As a reference, my car on a stock turbo and 91oct and a custom Dyno tune by KMS made 160whp and as a comparison bone stock my car made 122whp / on an Evo stage 2 my car made 147 / and KMS custom tune made the 160whp. All of these were on 91oct. pump gas, my big tune made +38whp over stock.

My car was already making the "claimed" +whp gain with the BD turbo upgrade on the stock turbo when tuned correctly.

Not exactly, their 200whp is based on a stock 17 making around 125whp... Showing about a 75whp gain over stock.. The BD kit is 200whp however on their Dyno a stock 17 makes almost 160whp, so its only a 40-45whp gain over stock.

Dyno numbers don't mean much, its about the actual delta/gain from the stock reading to after.

I hate to post on a thread with another vendor in the title, but I'd like to clarify a few things on these turbo setups.

If you are just throwing a bigger wheel into a turbo, you can spin the turbo at less RPM to make the same amount of boost. This is a good thing. Tuning won't be effected enough to change, but you will be able to go higher in boost than before as your turbo will be able to create more air if requested.

If you machine the housing and do a bigger wheel yet, thats the next step. It also allows you to clearance to near factory spec so that if you have a bearing that's not so perfect after some hard miles, you don't start eating into your housing and stopping the turbine from creating boost.... more wiggle room and more room to grab air.

The exhaust side: This is where we see an issue with EGT's skyrocketing with larger tunes as the turbine wheel limits exhaust flow and "stuffs" the motor. Having a higher flow exhaust side on your turbo can really boost your horsepower per octane rating when added with the compressor wheel. Many will say the higher flow exhaust turbine will create more lag. If your compressor wheel is lighter and creates more pressure per RPM, you don't lose anything down low (many times still gain response).

We'll have some information to share in our own post within a few weeks.

This right here, I'm surprised no one else has commented on the EGT's!!!

Again, I'm holding my experiences with this setup to my self right now because I want to hear what others have experienced with it using the BD tunes as well as their own custom tunes.

correct the factory turbo is only good for so much but with less risk of detonation and lower temps you can run more timing. I'm running AA stage 5 and the increase in timing is definitely noticeable to say the least, kinda gives that old feeling of the "powerband" hitting on you're dirtbike when you were a teenager if ya know what I mean :devil
 
#52 ·
Yep and that's what I would expect, essentially you are making similar octane numbers with the 91+meth inj. In theory I should be able to run the AA stage 4/5 on 91 with the correct amounts of meth inj. I haven't tried it with just 91 bc I've been running c12 all the time anyway right now, but I'm not burning through 30 gallons in a weekend. I go out around here and ride all day and maybe burn 5 gals on the trails. I do want to find that right setup for 91 with meth though bc I am planning to make a dune trip next year sometime and it would save me some money and from having to bring a bunch of race gas with me in the toy hauler.

Re: Boondockers Dont buy from them

I would not buy anything from Boondocker I have given them my business several times and I have had to many problems ...they seem nice but when a issue arises and even if they admit it is their fault you will still get screwed!! I am in Idaho and have tried to be loyal but without going into great detail I would steer clear!

I am sorry that you had a difficult experience with them.

I have had quite the opposite experience with Boondocker...without going into details...they made a mistake when they installed their turbo kit on my car...which was catastrophic to my engine....and they completely stood behind their work...replacing my entire motor...making it better than it was originally.

They are the most upstanding bunch of guys I have ever dealt with in the aftermarket industry.

My car now runs flawlessly...and rips!

I highly recommend them!

Curious to see more bolt in turbo swaps... I can say Mike at AA if a great guy and I will do recommend him hands down. And I'm really curious about a turbo he may be coming out with and I may have to jump from my EVO/HCT stage 4R set up... but time will tell.
