Oh hah with your comment I thought you were using something else..

So your only running 10lbs on the turbo. How much would you recommend for me, given the bone stock internals?

I look forward to talking with Hubie to see if we can figure something out..

Thanks to everyone for the help. Again, keep the input coming.

 

give or take 10 lbs yeah... or it could be a 12 lbs spring.. I forget...

it's not boost that hurts the motor.. it's detonation... so if to avoid that with 93 octane you shouldnt boost over 22-24... depending on your IC set up.. you may get away with more.. but just know 22 lbs with the 2871... depending on your base numbers and mods can net you around...250 or so WHP

 

Get the Neo, it has 3 more bands of RPM that you can adjust & its in Colour to boot! I have both the select II and the Neo, now I havent got around to installing the Neo yet still debating if that is ultimately what I will run for tuning.

As for Blow off valves, that is up to you on sound preference, but most of us are running the HKS sequential BOV. Most guys run them on the Scoobies or Evo's. There isnt any tweaking involved, so its an easy plug and play device. It is a slick unit, however It whistles while it works instead of whooshing. I do believe that its the plastic diverter it has over the valve that is causing the higher pitch whistle. I may leave mine off to see, as I have disassembled my to powdercoat.

As for the A/R ratio of the turbine housing(Area to Radius Ratio)Generally the larger the number the higher the flow capability. However .86 would be too big for our small displacement & would recommend the .64. It would have some serious turbo lag. This applies also to the Compressor housing.

Here is a link to a pic showing visually how the A/R ratio is found.

As for the T25 that is the flange size for the inlet of the turbine housing. That is a standard size, so any T25 should fit up to any T25 exhaust manifold. The internal wastegate is exactly that, it is internal to the turbine housing. This keeps the release valve inside the turbine housing making for a much more compact setup. The other option is an external wastegate. This is a bit more complex but in your application and room in the engine bay doesnt warrant the need for this setup.

hope that helps!

 

get the purple fitting.... no more squeek jsut a nice phazing whooshy thing going on... I tried cutting out the other one.. and while it sounded ok.. it's is not nearly as kewl as the purple one...

 

Ok. So I got back from seeing my best friends brand new 997 Carrera and I decided I was going to have a new plan of attack. Another friend of mine is getting a 335i Coupe in a couple of months so I've decided to just do the twincharge the right way.

Up until now I had the fastest car of my group of friends (sad huh lol). I'll let them have their fun but when I go twincharge I want to put bus lengths on the Carrera, and 250whp isn't going to do that for me.

So. Tuls some advice once again. I am going to shoot for 350-375whp so I thought about adding the following to the previous list:

RMW Head
Cams
Pistons
Front Mount Intercooler

Would that get me there?

 

Oh yeah! I do not mean to speak before Tuls, but as long as you engineer this kit correctly of coarse you can reach that goal.

 

Haha thanks for the quick response. Didn't mean to just call out on Tuls' advice, as always, everyones advice/opinions are welcome.

When the time comes I'll probably be working with Jan on putting something together and just source the parts that aren't custom on my own to save a little bit of cash where I can.

I would imagine it would be something like $6,000-$7,000 all-in.

 

its deffinetly possible... having a "strong car" will be needed... and maybe a gt2876 would be better.. but I am not sure....

 

ha ha hey I am not the be all end all... but this is pretty much right on... as long as you are willing to take the time to do it "right" you should be good to go

I still cannot stress enough how much easier it will be to reach this HP with turbo only...

 

Tuls car is a genetic freak....like say Shaquel O'neil style.....

I 2nd his motion of turbo only.....I was only able to get 257 whp at 20 psi, but closer to 300 at 25psi in the twincharge setup....im shooting for 400whp on the turbo only with the new engine i built using the RMW head & CP pistons. Everything else is custom but I am running the GT3071R turbo with water/meth. Tuning is still up in the air, but may try the Hydra if I dont like the way the car runs on the Apexi that I am currently running now...I have most of it done, just need to finish up the engine swap but that will have to wait until I get back from Italy.....

 

Turbo only is just soooo much more expensive, it's something that is CERTAINLY not do-able with my low-level income...

I notice you didn't have a head or pistons on your twincharge setup. I'm hoping the head will allow for the extra flow and ponies needed to net me as close to 350-375whp as possible.

Ultimately I'm just shooting the **** and throwing ideas out there. Obviously I have to work around what I'm willing to spend so I'll have a good long chat with Jan in the next couple of months to figure out a plan of attack for buying everything. I guess it'll likely start with the head, cam, pistons, and a tune. Then add in the injectors, turbo and everything needed to make it work at the end.

 

here is a nice Turbo only project that looks really good, almost like its from the factory!

Chris.

 

Ryans car was great while it lasted.. that monster will be missed dearly. BTW, if you can get the Hydra, I would reccomend it. works wonders on Subaru's, and other applications.. Besides, its the only real true standalone for the Mini...

 

Hey how much was Ryephile putting down?

 

I looked for info on the Hydra but didn't find anything on Alta's website. Any idea as to price? Does it come with any base maps? To my understanding, the stock ECU stays on the car connected to the Hydra in order to send RPM values to the dashboard? Or does the Hydra do that on it's own?

What he said. Never knew how much he was putting down.

 

EDIT: DOH! woops this is Tüls forgot this isn't my computer.... my comp is rendering...

 

I asked about the progress on the Hydra in Alta's Q&A Thread a couple weeks back and this was the response from Alta:

"Yes and No. It is available only for clients with TWURBO sytems. I do still have a few kits available.

But we have a NEW Ecu product the ALTA PnP ECU for the R53 that will be released in the coming days. For a sneak peek at what we did for the R56 owners click here!

Thanks again for asking!"

 

Motec...

and to everyone who's on this standalone kick... just remember.. you dont NEED it... Jan can scale the injectors among anything else in the factory ECU... I am still running the factory ecu... as well as kalbone...

but if you are going to do it... Motec is the way to go

 

Does Jan use the Dimsport Genius for his flashes? Or is there another Dimsport software that works with out cars that I am not aware about?

*EDIT*

Forgot to mention, last night I did some rough calculations and even getting some parts cheaper than MSRP you're looking at about $7,000 NOT including labor and miscellaneous fittings, lines, etc.

At this point, how much more labor and parts are you looking at to do away with the Eaton all-together?

 

uhhh I dunno where but I made a list.... I have spent 7.. so you are right on... but now I am still looking at a few more things.. intake manifold... water pump... more misc stuff.... fuel system.... it adds up... 10 is the minimum I would say you SHOULD spend... do it right...

I think Jan does use Dimsport... but unlike wanna be tuners... he has accually gone into it and gotten serious results... I say that cause he can do things no one else accually can... I always worked around certain things.... where he can just control them directly... I am impressed... and no one else will be doing anything to my car beside Jan... or my self (if I ever get the $ for the stuff)

 

Happens to me too. . . . DOH. . . This is Yucca. . . .
