    George did you pancake the pipe going behind the engine? How did you attach the pipes to the compressors? Silicone couplers?

    18wheel is great!

    Front and back are pan caked. Silicon reducer to attach to turbo.

    Pancaking makes sense, you have more room for insulation tape or something in case the tubes are SS. Or for a slim stainless shield in case the tubes are plastic/carbon.

    pancaking doesn't hurt anything in this case as its on the intake side and the main thing is surface area and length of piping

    fwiw, asr told me they dyno'd with the intake tubes completely off (a while back, on their stage 1 gen 1) and it made little to no gain (could be a white lie of some sort, shiv was apparently there, at the dyno session, he maybe able to verify although many on this board do not take his word highly. this was with v3). however, with stage 2, they expect a gain to be had with larger intake connections to the turbos. everyone seems to be showing the front pipe. the front pipe is easy! lots of space, at least compared to the rear. what i and i expect everyone else watching this thread want to see: the rear pipe (positioning behind engine), the connection to the turbos, etc.

    Few believe Shiv, NOONE trusts asr. I won't be surprised when 39 rwhp is gained on an RB car at high boost

    Do you know what they made at ASR back then? 530+ on a dynojet...doesn't that seem like the pipes helped and that ASR went hush hush on it as they were marketing their turbos and not the fact you can pick up a bit of power with the pipes taken off Click here to enlarge

    Can't wait to do these pipes now lol Even Shiv recently said they "may" be worth 10-20whp, hint hint

    it totally makes sense now actually. how did they make that 540whp glory run? 2 carpet dryers blowing air and the intake tubes off i guess, that rear turbo must have been pulling some hot ass air though. shiv maxed at 518, i'm guessing intake on? then his 'hint' would be spot on.

    Yes, but he was on a high reading dyno...that dyno with FBO and ASR turbos baselines at 296-300...mine baselines at 282 for instance...so he's in the 500 range but obviously took advantage of the higher baseline for marketing like any dirty businessman would hehe

    My 135i baselined 295whp on stock boost, but made 424whp on 18.5 psi with stock turbos. My 335i baselined 277whp but made 407whp at 17.5 psi @ 5000 RPM, both STD corrected.

    ambient temp for the 135i pull was 91 degrees, 335i ambient temp was 26 degrees. I'm not sure if that has anything to do with the varying dynojet baselines/peak numbers? Regardless, the delta is what's important; both deltas were right around 130whp.
