    MAF conversion legal for DSP??

    Topic not completely answered on Bf.c. Made me curious.

    C. Carburetors, fuel injection, intercoolers 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. As utilized only on engines originally
    equipped with forced induction, air-to-air heat exchangers (known
    as “intercoolers”), and radiators which are part of air-to-liquid
    charge coolers, must be cooled only by the atmosphere.
    The use of chilled liquids, ice, dry ice, refrigeration systems,
    vaporized compressed gases, etc. is prohibited. 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. Turbochargers may not be added, changed or
    modified. Turbocharger and supercharger systems may only be
    updated/backdated with the accompanying engine unit. No
    changes are allowed to waste gates, pressure sensors or their
    location, and to other turbocharger or supercharger boost limiting
    systems. Any device which is part of the Stock induction system
    and serves to limit or otherwise control boost is required to remain
    in the original configuration unless a change is explicitly
    authorized herein. This restriction does not permit changes to
    blow-off (pop-off) valves. Devices known as “fuel cut defensers”,
    and any modifications which alter or defeat the fuel cutoff when it
    is activated by boost level, are not permitted. Compressor bypass
    valves (CBV’s) may be updated or backdated independently of the
    other components of a turbocharger system.
    D. Air cleaner(s) may be changed or removed, velocity stacks may be
    added.

    Anyone want to confirm Charlie's conclusion?


    I was asking around Bf.c for STX versus DSP, and read conflicting opinions about which would be better......but:
    As far as STX vs. DSP for me.....19# injectors and my new 4.10LSD kinda determine that, unless I want to swap back down the road.....let's see how lonely DSP is locally, I might be the only one out there. Oh well. And tires would cost more down the road if I was looking at changing the car to let me be competitive......

    Maybe I'll eventually come to a point I'll want to backstep to STX, I dunno. But tires, mods, or class don't really matter now, do they? Just thinking ahead.

    I don't think you need to be worry about your class and mods yet. Just go into whatever class your current mods put you, and start from there. You will shortly be able to tell what you really want to do after a few autocrosses.

      The MAF would be legal for DSP, it would not for STX.

      As I said.

        I haven't read it expressly anywhere and I didn't want to incorrectly take anything away from the rules. But I had a couple local guys confirm it. I might have wanted to do something this summer and wanted to be cool for the future.

          Local guy runs DSP with a MAF in the car on an 89 325is, no one's protested him for it. Basically, anything above the head of the engine is unrestricted in SP.

            also does the classification rule still say "all 325 bmw" on the same line? if so a 2.5/24valve is legal in DSP in an e30. It was about 3 years ago have not seen a rule book in a couple years. PM me for cost effective ways to increase DSP performance.

              No, they zipped that one up after the "88-89" Honda Civic Si debacle a few years back.
              FWIW, a non-vanos 24v was the motor. Basically, the wording was done to include the 92 cabrios, but was done poorly enough to state "84-92 3 series".

                alright, cool. I've gathered that a cam, turbo, or swap will land a car in SM. But yeah, any external work seems to be cool. Just wanted to be sure.

                  and
                  5 lug conversions are illegal
                  big brakes are illegal
                  anything inside the engine that the factory manual doesn't aprove are illegal
                  removing too much interior is illegal

                  go to search and you will find a list (outdated now) of Alex Shchipkov's suspension
                  nevermind here

                  Yep, you are right, it is out of date. You probably got it from http://teamsoloracer.com
                  I definitely need to update that list there.

                  If you want to run STS and not have to deal with an open diff get a 3.91 out of iX with viscous diff. I think E30 non M3 can be fairly competitive in STX.

                    I'm looking at an older car classification sheet and it says brake larger than stock are allowed, but the newer rules if my memory is right don't allow for that. I'm in class right now, but I'll check it out when I get back.

                    The true need will probaby be big hoo-hoos or kuhmos as I slowly eventually reach that point. Damn DSP and expensive R compounds......

                      any local racers in ITS ITA? go get thier take offs! good sets from fast teams will have tread left and will cost you about 100 per set or less.

                      now the r compounds are out of the problem area

                      NEXT.....

                        oh yeah. someone gave me a set of r compounds while they were cleaning out their garage. and another guy in the cca races j-stock e30 m3 and usually has a few sets of hoosiers around he would probably sell cheap. 8) (when the time comes.....) awesome.

                        and I'm pretty much going to match most of Alex's mods on that list, aside from the massive wheels and tires, and swaybars (for now).

                        and I think the 3.91 wouldn't be allowed because of the gear ratio changes.

                          Full 05 rules.

                          Diff changes are legal in DSP.

                              Which class are you looking to run Heeter?

                              In ST S/X, diff swaps are not legal, in SP, they are.
