Just got done with a board meeting for our racing club. Talked to an engine builder. Mentioned this spacer. They tried it on evo motors on the dyno. Pressurized system made no difference.

 

Looks like this thread is going to save me money, time and no bloody knuckles

 

I went for a test drive and everything runs good, not sure if I can tell a difference. I'll run it for a week and decide.

Very little clearance with the airbox and the firewall. A small frivolous piece on the back driver-side corner of the airbox was nearly touching so I trimmed it off.

One thing to think about if you are using a strut tower brace... it may no longer clear. The NM brace does NOT work with this modification.

 

That's not good, we all know how much our engines moves when running it hard. I think I'll pass on this mod, I just can't because you're going to have clearance issues between the firewall and airbox/manifold.

 

Let me clarify on the clearance; I can still slide my pinkie finger in-between the firewall and airbox so I'd imagine that should be ok.

Truth be told, I really want this mod to work. The quality is there, the little MAF spacer looks good and the claimed dyno numbers are nothing to sneeze at.

No matter how it eventually works out, I enjoyed doing it and learned more about the car.

Pic of it installed. Notice that the intake runners are more visible.

 

will wait for the feedback.

I remember when mine was that clean. That's the day i brought the mini home.

 

.................................................. ....

 

my wallet is ready to buy but want to hear more.

 

I'm trying to get both of my friends dyno readouts for yall, this is a high quality low cost item, and not sure why all this discussion is needed it's not a major modification. I think the cheapest easiest way to add bhp is to change out that turbo exhaust tube which BMW puts a little muffler , swap that out and I think you get 5 bhp instantly. Intake? Better turbo, turbo nanifokd? Intercooler? These where the mods I did that made a huge improvement.

 

i would think my mini dealer is going to give me trouble when i take my r60s for an oil change and inspection? warranty runs out in December and that is when i have to visit them

 

The dealer typically only gives people trouble when something breaks then they could deny the claim. But if your warranty runs out in December then I would wait, Murphy's law and all that.

 

In the butt bob oops I mean by the butt Bob.
I do wonder if forced air induction benefits form the longer intake runner. Change the torque curve but horsepower. We need a dyno run.

 

Mind snapping a pic?
You didn't have one on your car when you posted pictures last week.

Now you've got one, and know you got zero HP from it?
(I assume from your Scangauge? since you didn't dyno)

I smell a troll.

 

I was hoping for some positive results from this mod, but one of my problems is, I'm close to 300hp on my GP and 10hp is not going to be noticeable at all. 10hp might make a difference on a stock Mini. My ported/polished ceramic coated stage 3 exhaust manifold seems to give the car a good punch, the runners are more even, smooth and 5mm bigger each

 

I agree it should be part of the kit. Call me particular, OCD or just plain **** retentive, but IF I install this mod later on I'd have to make a small bracket for that. Otherwise, knowing that support wasn't being used would just bug the ever-lovin hell out of me.

 

So is the consensus that this is not worth the money?

 

sorry it does not ... had my car hooked up to my buddys highend pro scan tool (used in his transmission repair/overhaul shop) ... it showed us both the pedal position and the throttle position ... the scan gauge shows the throttle position NOT the pedal position

the throttle is NOT held wide open ... how ever it is held open more than most cars at idle, about 8-10% seems very engine temp dependant, and apparently the variable valve lift and timing is used to regulate idle speed

we did confirm 17-18% throttle at 70 mph in 4th 5th or 6th gear

also confirmed that flooring the pedal does not result in 100% throttle ... you get 85-90% until the revs are high ... above 5k

we also found that on cruise, the pedal position shows 0% while throttle % varies as the cruise maintains set speed ... again seeing about +/-17% at 70 mph

so more nonsense internet knowledge put to rest

 

what i seem to understand and i am a noob is that if you already have a heavily modified mini you wont notice it but someone with a jb+ cai it would make a difference. its a cheap mod compared to other things like cai's. even if 3-5hp gains i think its worth it, or the engine runs more efficient.

 

Cooler air intake temps would be plenty for me to pick one up. I think I'm going to design a "reverse" manifold spacer/mount...

 

Oh do tell!?

Since mine is mostly stock, after reading and re reading the thread a few times, I figure I will go with it. I can't afford Dyno time (Hey, a man needs his ramen, and his beer) but I'm happy to report from Torque Pro and or the all knowing butt dyno.

 

It is interesting that the throttle apparently does not remain fully open. However, it doesn't change the fact that it is effectively not in use, evident by the lack of vacuum. At least this is the case when not in boost.

Edit: Had another thought. Are you sure that the value you are reading isn't actually the valvetronic "throttle" position? That is, the percentage of valve lift.

 

no ... the vanos reads separate from the throttle

 

VANOS is the timing though, not lift.

In any case, I thought about the issue a bit more and now I'm thinking that the valvetronic might not make a difference with this mod anyway. An engine with a traditional throttle vs. a valvetronic engine probably behaves the same way at WOT because the intake path is fully open. That would mean the intake riser has the same benefit, whatever that is.

 

My spacer is going to make more than 10 hp.
Dyno numbers coming soon after i get the correct nozzles. Center 2 are mock up at the moment.

 

Awesome! Is that a Meth system I see there?
