I'm still running TSM, so you'd only have to run against qksubi and Larry Capen in BSP.

fng's don't pick a class?

BanSuv, Great plan, :) i'll run in a class alone, (and hopefully win) LoL
do they actually hand out jackets ? or just bragging rights of "i got the jacket" sorta thing?
Course maybe i could talk SilverSTI into doing a Silencer Delete so he ends up in STU as well. :lol:

Hey Brian, Why don't you run STU? I just glanced at the card, but better pax, and you could win a jacket!!!

only if he can beat me and my lousy driving, oh wait he is already beating my times easily ... hmmf. what's that about careful what you wish for ? (he wouldn't even have to mod his intake huh? you can optionally choose to run in higher classes ?) He's a better drive then i am, but i would love the compitition. :P

Actually, TAS has a much better pax than STU. And competition is always good, which is why moving to BSP might be a good call for you stock/near stock STi guys. ;)

would i be Competitive or just be sacraficed in BSP with only my air intake kit ? (guess when i learn how to drive i'de be set) :)

You sure I can run an MBC Kevin?

Edit: I'm asking if an MBC would kick me out of ESP.

Umm ... don't you already have a custom pro-tune? Why do you need an MBC?

No, it wouldn't, but it isn't going to work very well on a Subaru...

If you don't already have a custom tune, buy Scott's ECU with EKUTek licence cheap, and get one. Better than any MBC.

I have a custom tune. MBC's are bad on a stock ECU, but a good MBC should really help my boost response and isn't dangerous with a tuned map. Ed suggested it and assured me there's no need for a retune.

Thanks for the info.

Think of it this way: if you install a MBC and set it to say 15 psi, sure you'll run right up to 15 psi in 1st and 2nd gear as soon as possible, and you'll avoid some of that boost wobble due to the factory EBC, but you're not going to be able to taper boost at high rpms. If you think you can run a stock turbo at 15 psi at 6500 rpm in 4th gear down the backstraight at RFR all day long, I've got a 2.0L shortblock in my garage I'll sell you, 'cause you'll need it. So, you're going to have to set the MBC to say 13 psi. Granted you'll have a nice rock solid 13 psi all day in every gear (well until the weather changes and you're under the hood w/ an allen wrench), but I'd rather have that 15.5 psi when it's safe and the taper to 13 psi on the top end making sure my motor will last.

If MBC's were so great, I'm pretty sure Subaru would have put one on the car to begin with 'cause they're about 1/50th the cost of the EBC.

Now, correct me if I'm wrong, but doesn't an EBC and an MBC bump you into SM? Since the boost is being altered in the ECU tune, isn't that considered modifying the EBC and adding an MBC, therefore putting you into SM?

But I thought there was a rule stipulating that you could have electronic and manual means.

I haven't had time to look at the rules in detail, this was just something I remember hearing.

Think that covers it.

I RTFRB but didn't see anything about IC Hoses. Can anyone drop some knowledge on me please?

You can't do anything between the turbo inlet and the throttle body, except for the IC.. so I dunno actually.

You can touch pretty much anything you bloody want in SP now except the turbo and wastegate. Reread 15.10.c

No. It's really a non-issue for me, nothing other than the longblock is off-limits for NA cars. ;)

I'm just going to RNP this season. Given the fact that I can only race sundays. However this is a good thing, given the fact that I can't be competative I have no reason to swap in another 16 valve, so in goes the AE111's 20 valve.

I reread it again but I still don't know.

C. Induction allowances are as follows:
1. Carburetors, fuel injection, and intake manifolds are unrestricted.
Alternate throttle linkage and connections to facilitate
installation of allowed induction systems are permitted,
but may serve no other purpose. If an induction system item
is allowed to be removed and its original mounting bracket
can be removed by simply unbolting it, the bracket may be removed
as well.
2. Except for standard parts as defined in these rules, the external
use while on course of liquids, ice, dry ice, refrigeration
systems, vaporized compressed gases, etc. to reduce the
temperature of the intake air charge is prohibited. Wrapping
of intakes with liquid-soaked fabric is not permitted.
3. As utilized only on engines originally equipped with forced
induction, induction charge heat exchangers (known as “intercoolers”
or “charge air coolers (CACs)”) are unrestricted in
size and configuration. Air-to-air CACs and radiators for airto-
liquid CACs must be cooled only by the atmosphere, except
for standard parts. Body panels, fascias, or structural members
may not be cut or altered to facilitate CAC installation.
4. Turbochargers and/or superchargers (“forced induction”) may
not be added, changed, or modified. On vehicles originally
equipped with forced induction:
a) No hardware changes or alterations to turbocharger(s) or
supercharger(s), in size or number, are permitted. Turbochargers
or superchargers may be updated/backdated only
in conjunction with the accompanying complete engine
unit.
b) No changes are allowed to waste gate(s) size, number, or
location. No changes are allowed to variable-geometryturbine
(VGT) hardware.
c) No changes are allowed to supercharger drive system
pulleys. Belt tensioners may be added/changed to reduce
belt slip.
d) No changes are permitted to blow-off/pop-off valves.
e) Compressor bypass valves (CBVs) are considered part of
the air intake system, and may be replaced or updated/
backdated independently of the other components of a
forced induction system.
f) Boost regulation systems, either electronic or mechanical,
and electronic fuel cuts referencing boost pressure may be
altered or modified except as prohibited herein. Boost
pressure changes resulting from authorized changes are
permitted.

OMG... If you can change the IC, you can change the hoses....
